Distribution box It is mainly installed outdoors. But in the process of use, why does it have the phenomenon of leakage? Let me give you a brief explanation today!
This phenomenon occurs, mainly because the ground wire is not connected well or is not grounded.
Secondly, if the equipment on it is found to be aging, there will also be leakage.
Faced with this situation, it is necessary to check whether the wire is not connected properly or the wire is aging.
In daily life, if it has leakage, then it is necessary to find out the reason.
Correct line configuration scheme skills can save time and lines, which requires us to master certain techniques and skills. Follow these tips to wire for best results. Necessary safety measures should be taken when arranging power distribution equipment. If there is a bare charged body with a dangerous potential, it should be covered or placed out of the reach of people.
1. Address selection. The location of the low-voltage power distribution room should be close to the load center, set in a place with less dust, less corrosive medium, dryness and slight vibration, and appropriate room for development should be reserved;
2, the layout of power distribution equipment. The layout of the power distribution equipment in the low-voltage power distribution room must follow the principles of safety, reliability, applicability and economy, and should be convenient for installation, operation, handling, maintenance, testing and monitoring. Appropriate distances and passage exits must be reserved for high-voltage electrical equipment and low-voltage electrical equipment in the same room, as well as power distribution cabinets arranged in rows. Necessary safety measures should be taken when arranging power distribution equipment. Bare live objects with dangerous potential should be shielded or placed out of reach of people. Barriers can be used for protection when it is difficult to use shields and covers
3. The layout of the distribution line should meet the conditions: conform to the characteristics of the site environment; conform to the characteristics of the building; the degree of accessibility between people and the wiring; the electromechanical stress that may occur due to short circuits; the wiring may be during installation or in operation. Other stresses experienced and the self-weight of the wire.
Fourth, the layout of the distribution line should avoid the influence of the external environment: the influence of the thermal effect of the external heat source should be avoided; the damage caused by the intrusion of water or the entry of the group objects should be prevented during use; the external mechanical Influence caused by sexual damage; In places with a lot of dust, the influence caused by dust gathering on the wiring should be avoided; The damage caused by strong solar radiation should be avoided.
Distribution box composition is mainly divided into two parts. One complete set of components, i.e. power distribution box shell and its related accessories. Two electrical components and related accessories, i.e. air switches and their required accessories.
The cabinet is composed of the following parts.
I. Circuit breaker: both switches, is the main components of the distribution cabinet, commonly used air switch. Leakage switch. Double power automatic transfer switch.
1. Air switch.
A. The concept of air switch.
Air switch is also known as the air circuit breaker, in the circuit for connecting, breaking and carrying the rated operating current and short circuit, overload and other fault currents, and can be in the line and load overload, short circuit, under voltage, etc., quickly break the circuit, for reliable protection. The design of dynamic and static contacts and contact bars of circuit breakers are various, but the main purpose is to improve the breaking capacity of circuit breakers. At present, the use of certain contact structure to limit the peak short-circuit current limit principle when breaking, to improve the breaking capacity of the circuit breaker has an obvious effect, and is widely used.
B. Working principle of air switch.
Automatic air switch, also known as a low-voltage circuit breaker, can be used to turn on and break the load circuit, and can also be used to control infrequently starting motors. Its function is equivalent to the sum of some or all of the functions of the gate switch, over-current relay, loss-of-voltage relay, thermal relay and leakage protector and other electrical appliances, and is an important protection appliance in the low-voltage distribution network.
Automatic air switch has a variety of protection functions (overload, short circuit, under voltage protection, etc.), adjustable action value, high breaking capacity, easy operation, safety and other advantages, so it is now widely used.
2. Leakage protection switch.
A. Leakage protection switch concept.
Both with leakage protection function, people touching the charged body will trip to ensure personal safety, is the main function of the leakage protector; electricity-using equipment if the insulation is not good leakage to the shell, the leakage protector will also trip to avoid human touch electrocution. It also has the function of current flow interruption, overload protection and short circuit protection.
B. The working principle of the leakage protection switch.
The working principle diagram of the earth leakage protector. LH in the figure is a zero sequence current transformer, which consists of a core made of PoMo alloy, and a secondary coil wound on a circular core to form the detection element. The phase and neutral wires of the power supply pass through the circular hole and become the primary coil of the zero-sequence transformer. The rear line of the transformer is the protection range.
C. The role of the leakage protection switch:
1, when the electrical equipment or line leakage or grounding fault, can cut off the power supply before the person has touched. 2, when the human body touches an electrically charged object, can cut off the power supply within 011s, thereby reducing the degree of injury to the human body from the current. 3, can prevent fire accidents caused by electrical leakage.
3. Double power automatic transfer switch.
A. The concept of dual power automatic transfer switch:
Dual power automatic transfer switch for power two-choice automatic switching system, after the first road failure dual power automatic transfer switch automatically switch to the second road to the load power supply, the second road failure then dual power automatic transfer switch automatically switch to the first road to the load power supply. Suitable for UPS-UPS, UPS-generator, UPS-utility, utility-utility and any two-way power conversion.
II. SPD
A. The concept of surge protector.
Surge protector, also known as lightning protection, is a variety of electronic equipment, instruments, communication lines to provide safety protection of electronic devices. When the electrical circuit or communication lines because of external interference suddenly produce spikes in current or voltage, surge protector can be shunted in a very short period of time to avoid damage to other equipment in the circuit
B. Surge basic knowledge:
The main function of a surge protector system is to protect electronic equipment from damage caused by "surges". So, if you want to know what a surge protector does, you need to understand two questions: What are surges? Why do electronic devices need their protection?
A surge, also called a surge, is, as the name implies, a momentary overvoltage that exceeds the normal operating voltage. Essentially, a surge is a violent pulse that occurs in just a few millionths of a second. Possible causes of surges are: heavy equipment, short circuits, power switching, or large engines.
A surge or transient voltage is a voltage that substantially exceeds its rated level during the flow of electrical energy. In the United States, the standard voltage for wiring in the average home and office environment is 120 volts. If the voltage exceeds 120 volts, problems can arise and surge protectors help prevent that problem from damaging computers.
C. The role of surge protectors.
The first line of defense should be connected to the user power supply system inlet line between each phase and the earth's high-capacity power supply surge protector. General requirements of the level of power protection device with 100KA / phase above the maximum impact capacity, the required limit voltage should be less than 2800 V. We call CLASS I level power surge protector (referred to as SPD). These power supply surge protectors are designed to withstand the high currents and high energy surge energy absorption of lightning and induced lightning strikes, which can divert large amounts of surge current to earth. They only provide limiting voltage (the maximum voltage that appears on the line when the inrush current flows through the SPD becomes the limiting voltage) as a medium level of protection, because CLASS I protectors are mainly for the absorption of large surge currents. They alone cannot fully protect sensitive power equipment inside the power supply system.
The second line of defense should be installed in the power supply to the important or sensitive power supply equipment at the branch distribution equipment of the power supply anti-surge protector. These SPDs provide better absorption of the residual surge energy that passes through the surge dischargers at the customer's power supply entrance and provide excellent suppression of transient overvoltages. The use of the power supply surge protector requires the maximum impact capacity of 40KA / phase or more, the required limit voltage should be less than 2000V. we call CLASS II power supply surge protector. The general user power supply system for the second level of protection can be achieved by the operation of power equipment requirements.
The last line of defense can be used in the internal power supply part of the power equipment with a built-in power supply anti-surge protector to completely eliminate small transient transient overvoltage purposes. The use of power supply anti-surge protector required for the maximum impact capacity of 20KA / phase or some lower, the required limit voltage should be less than 1800V. For some particularly important or sensitive electronic equipment, with the third level of protection is necessary. It also protects the power equipment from transient overvoltages generated within the system.

When the distribution box is running, it is inevitable that there will be failures. For some common faults, some improvements can be made to the distribution box.
1. If the power distribution platform on the column is added, when making the shell of the distribution box, a stainless steel plate with a thickness of 2mm can be selected, and the size of the distribution box shall be appropriately enlarged in proportion to increase the distance between the outgoing lines of each branch, the outgoing line and the box. The electrical safety distance of the housing. This is conducive to the operation and maintenance of agricultural electricians and the replacement of fused parts, and it can also dissipate heat.
2. Selection of residual current action protector. Products that meet the GB6829 standard and have been certified by the China Electrical Product Certification Committee must be selected. A power-saving and low-sensitivity time-delay protector similar to the LJM (J) series can be selected.
3. A protection circuit is used to prevent the occurrence of external circuit failures powered by the distribution box. Choose an intelligent phase loss protector with a smaller volume, such as the DA88CM-II motor phase loss protection module, which is installed in the distribution box to prevent the motor from burning out due to low-voltage phase loss operation.
4. Selection of fuses. The rated current of the total overcurrent protection fuse on the low-voltage side of the distribution transformer should be greater than the rated current of the low-voltage side of the distribution transformer. Generally, 1.5 times the rated current is taken. The rated current of the melt should be determined according to the allowable overload multiple of the transformer and the characteristics of the fuse.
5. Improve the wiring method of the low-voltage capacitor bank of the original distribution box, and change its installation position from the top of the AC contactor to the connection between the low-voltage incoming line of the distribution box and the meter.

When the air switch is a three-phase switch, to figure out whether the incoming line is a three-phase circuit. If it is determined to be two-phase, it should be zero wire to zero wire, ground wire to the shell, fire wire casually connected to a can.

Before the intelligent building project, accurate understanding of the basic concepts of weak electrical engineering, system integration and intelligent building, especially for the use of what means of system integration is necessary to do a good job of intelligent building.
With intelligent building characteristics of the project, in recent years, many building construction projects in the range of investment, the trend is growing year by year. But in these construction projects, some of them can not be called intelligent building engineering, at best, is only a simple system integration project with BA performance, and intelligent building is still far from. There are also construction projects proposed to do weak electrical system engineering, and system integration, intelligent building link. But how to contact? The builder can not get a practical and feasible technical planning program, by the integrator there to do the leading opinion. Some buildings have a large area and form a related building group, with a strong integrated function, should have intelligent building features of the project, but often can not afford to invest, just do a few relatively independent weak electrical engineering to cope. The lack of the composition of a complete integrated network management system, to the future scientific management of the building property and the waste of resources brings great regret. Some builders, after examining the relevant projects and listening to some hype of the integrator, feel that the intelligent building is very good and do not hesitate to invest in this area. However, after a period of use, it is felt that the project does not play a good benefit, on the contrary, sometimes it becomes a burden for managers. Problems such as these. Investors and users are confused. What is weak power engineering? What is system integration? What is an intelligent building? Is system integration an intelligent building? How to define the above project. How to grasp the right amount of investment in construction, and in the future use of the process to ensure that the weak electrical subsystems and intelligent management of the building to achieve the purpose of the original expected, both for the investor and the user is very important.
Intelligent engineering and weak electrical system engineering, has been in some major construction projects with the building structure, mechanical and electrical equipment installation, interior and exterior decoration works as equally important unit project. However, due to the late start of intelligent engineering relative to other traditional construction projects, it belongs to the sunrise industry. At the same time involving the construction, information, public security, fire, telecommunications, radio and television departments in the above-mentioned engineering interface content of mutual cross difficult to coordinate, so negligible engineering standardization of the comprehensive specific operation of the standard and other phenomena. In addition, in the field of design, because there is no basis for the design of the project fee and fee collection standards, but the intelligent technology content of such a project by the building electrical engineering design fee, so the rate is very low, coupled with many design institutes also lack of intelligent building system integration designers. Therefore, most of the domestic Class A building design institutes are generally not active in the design of intelligent building engineering. This absence of design is often replaced by the integrator. Integrators to obtain the contracting status of the project, often free design for the construction side, while the integrators regardless of design experience and coordination of professional drawings and drawings between the depth of vertical and horizontal quality can not be compared with the formal design institute, resulting in the general low quality of design drawings phenomenon. This practice of putting the cart before the horse is very much affecting the development of intelligent building engineering. So in the acceptance of the above project, it is not difficult to find in the acceptance process of the overall traditional construction projects, intelligent engineering and weak electrical engineering but has become a weak point in the acceptance, or even a blank point. This is obviously at a disadvantage in terms of contractual interest maintenance for the construction party. Especially for the future use of the aspects of a very bad impact. There are many reasons for this problem, but one thing is undeniable, that is, in the preliminary work of the project, there is no accurate positioning of the above-mentioned projects, whether the construction of several separate weak electrical engineering? Also when the construction of systems integration containing intelligent features of the project. Therefore, a more accurate understanding and clear understanding of the difference between the above-mentioned projects and the basic concept is very necessary.
A. Weak electrical engineering is the basic unit of various building construction projects, has become an indispensable construction sub-projects in various construction projects. Both the current residential community construction, its weak electrical engineering construction has also been greatly improved, for example, from the original cable TV, broadband network construction to the development of the community's closed-circuit television monitoring, building access control, three meters far copy and scientific property management, etc.. With the rise of green building, it is possible that the combination of household appliances integration and home information network switches, servers will form a real intelligent building residential community and show great humanization, science and environmental protection. And the weak electrical engineering associated with it is essential. Especially in some large public buildings, the types of weak electrical systems are more extensive. It can be said that when making investment in weak electricity engineering projects, according to their own needs, they can disregard system integration and projects with intelligent architectural features, but when carrying out the content of system integration and intelligent building engineering, they must have the physical form of each weak electronic system engineering, because weak electricity engineering provides technical products, which are provided to the building and normally play an embodied technical function. For example, in the construction of closed-circuit television monitoring project, eventually can be in the monitoring room and sub-control room in a timely manner to obtain the site of the monitoring images and alarm signals, and in the hard disk recorder has a certain video retention time records, which will achieve the practical purpose. Such project cost is small compared with the overall construction cost, and easy to build. As for whether another information platform for BMS integration, that is a different story. If it is only for the realization of a certain function, and considering the limit of investment and the maintenance level of property management staff, you can temporarily do not blindly do a large system integration. There are relatively independent weak electrical engineering in itself with the integration conditions can achieve the proper function. Both the building has a large centralized air conditioning, do not worry about whether there is no BMS integration system will have a negative impact on the normal use of air conditioning equipment and other building equipment, these are two different concepts.
Second, the system integration is not a specific technical product, but only a technical means. For example, in a building, if there are many weak electronic systems and large centralized air conditioning, large public area lighting projects, mechanical and electrical equipment, water supply and drainage and other construction projects, and the system between the building equipment management and maintenance and information sharing needs are increasingly obvious, which should be connected through a new technical means to these relatively independent weak electronic systems and air conditioning, mechanical and electrical, lighting and other systems This will fundamentally change the traditional management model and realize the modular management of the system, which must involve many different manufacturers, different equipment components, and different software configurations, in order to make these products and technologies to achieve unity and coordination, that is, mutual matching, interconnection and interoperability, so as to achieve the integrated system of comprehensive and efficient management and system-related automation and information data collection and processing functions. In order to make these products achieve unified and coordinated technology, i.e., match each other, achieve interconnection and interoperability, so as to achieve comprehensive and efficient management of the integrated system, as well as the automation of the system and the collection and processing of information and data. This is obviously more complicated than doing several separate weak electrical projects. Because system integration requires related network technology, database technology, middleware technology base and other conditions, whether it can achieve the information sharing between each heterogeneous system is related to the success or failure of system integration.
BA, BMS and IBMS are the main system integration modes adopted in different types of buildings in recent years, which are also the integration means adopted according to the functions of buildings and the needs of users.
1, BA is a more common chiller, ventilation, power distribution, elevators and other equipment as the main mode of integration, usually referred to as "building automation" is mostly for the BA of this integration method. Of course, the comprehensive security project (SA) and fire engineering (FA) which is also relatively independent of the system integration, if the 3A integrated together through the information network platform, usually called BAS can also be called BMS integration. These two technical means of the way is basically the same, whether BA, or SA, FA which are relatively closed system, they are mostly developed by the manufacturers of the company's special network bus, does not have openness, so the system integration capacity is limited, and maintenance, upgrade costs are also very high, so that the BA as a platform for system integration is not the real sense of intelligent buildings. At present, such system integration is also very common in most construction projects. 2, BMS is mainly BA as the core through the second level of the information network platform and through information communication, protocol conversion and control module will be the subsystem operation data through the building's internal LAN in the form of a browser on the central monitoring computer to achieve the monitoring and management of the entire building operations, due to the necessary database and applications it can provide a complete operating interface, so that it can achieve the The system integration of mechanical and electrical equipment, security equipment, fire equipment, etc. to implement a unified monitoring and control, (commonly known as 3A) this model is relatively simple to achieve, the cost is low, the system can be well linked, is currently the system integration of the application of a more integrated mode. It has significant advantages in terms of safety, economy, reliability and interconnectivity, and it has a positive role in strengthening the unified property management report statistics, energy management, statistical decision-making, coordination of different professional management work information interchange between the subsystems. But there are shortcomings, if the building automatic control system failure downtime, BMS system is also paralyzed, losing the ability to work normally, and can not manage and monitor the rest of the subsystems still working normally, so the daily maintenance of building equipment management is very important.
2, IBMS is based on BAS further with the communication network system, information network system to achieve a higher level of building integrated management system. If BMS is built on the basis of 3A integration, then IBMS is another higher level of system integration built on top of 5A integration. (commonly known as integrated building) This type of integration generally consists of three parts: an integrated monitoring platform with Web functions, a monitoring server and a protocol conversion gateway. And it is also a powerful development platform can be established relatively fixed and more complex application system, can be integrated with the enterprise's resource planning system ERP application system to complete the integration of management and control work. IBMS is more prominent in the management of the function, that is, how the comprehensive realization of optimal control and management, energy saving, energy efficiency, comfort, environmental security such a purpose, so to speak To judge whether a building has the characteristics of an intelligent building, it depends on whether it has the system integration of IBMS. This is a very important condition for determination. Another important premise is that while doing this project well, do not neglect the simultaneous construction of information technology projects. A successful IBMS system integration will be able to play a significant economic advantage in many management aspects, which of course has a lot to do with the high quality of technology of the users.
After understanding the basic concept of system integration, it is not difficult to understand the intelligent building. Because the establishment of intelligent building model itself is to be realized through the means of system integration, through the optimization of multiple objectives; multi-disciplinary synthesis, multi-factor relevance, and ultimately to provide a high degree of shared information resources, improve efficiency, ensure the safety of building use, save management costs to achieve short-term investment, long-term benefits of such a comprehensive goal. The condition of intelligent building is based on system integration, but it cannot be completely equated with system integration, and there are still differences between them. As reflecting the comprehensive and extensive scientific characteristics of its intelligent building. There are many key work must be done carefully, for example, first of all, the function of the building and management mode to systematically analyze, to carry out a lot of investigation and demand analysis work, and sometimes also in the original integrated software based on the need to highlight the focus on property management, and then the secondary development of software, through a lot of careful work will eventually mature software applications and orderly realization of the subsystems of centralized monitoring It is also important to control and manage the subsystems. It should be said that the benefits of a good intelligent building is self-evident. But the construction side is easy to ignore the above-mentioned must do a lot of work, always like to copy the same type of project as well as by the views of the integrator sway.
Undeniably, in recent years, many large and medium-sized intelligent building projects, more or less also took some detours, often in the weak electrical engineering and intelligent construction, the lack of in-depth planning and demonstration work, not only wasted investment, but also make the system does not work as it should, and finally become a failure of the "look" project. Therefore, there is no shortage of cases of system integration and intelligent building failure.
In the current vigorously advocate green building, advocate saving society under such an environment, the different levels of future intelligent building construction content will be very natural to implement in the building construction projects, and thus will dilute the hype of intelligent building. And gradually towards rational investment and more tend to standardize the above project.
