Surge Protector and Lightning Box Installation Site Application

Posted on

According to the national standard GB50057-10, we know that the power surge protector/lightning protection box is to be protected in three levels, and the magnitude of the flow capacity is reduced step by step, that is, the first level is about the second level. Double the level, the second level is about twice the level of the third, then the inside of the power supply lightning protection box and surge protector, belong to the power supply lightning protection series, what kind of difference? Why do you need to install boxes in some places, and only install modules in some places?

First of all, we must know the structure of the lightning protection box and module. In fact, the real core is still inside the lightning protection module. There are core components, varistors or discharge tubes. Therefore, many of our distribution cabinets are equipped with The lightning protection module can also play a role in lightning protection. However, compared with the lightning protection box, both have their own advantages and disadvantages.
The protection function of the lightning protection box is more complete than that of the lightning protection module. In addition to the installation module, the lightning protection box has multiple protection functions such as an open circuit breaker and a circuit board. If the module is not connected properly or There is no problem whatsoever. The open circuit can also protect it. The components of the circuit board can also be protected again, so the safety factor is much better.
Secondly, the module is inside the box. In the event of a spark or a direct fire, the box also has the function of preventing the small fire from spreading out. Mars comes out and burns next to the flammable stuff. This can easily cause fire. Therefore, the box is There is something that the module does not have here.
Third, the lightning protection box has many extension functions. For example, he can carry the function of a counter. The module has no place to install a counter. The box can be further attached to increase the counter to see the number of lightning strikes at any time, and many places, such as The use of explosion-proof boxes in chemical establishments and hostile environments can only use lightning protection boxes, confined spaces, and the appearance of sparks in lightning protection. It can ignite the gas and cause explosions and fires. Therefore, the box has one more advantage in terms of additional functions.
Fourth, the lightning protection boxes are usually made of stainless steel or iron sheet. The boxes can be protected to the inside modules, air breakers and all wires, and the components are not affected by the influence of moisture on their lightning protection life. If the lightning protection devices are damp, not only Thunder does not work well, and it is also prone to safety incidents.
Fifth, the lightning protection box has been formed, and it is also very convenient to install. Just play a few holes, hit a few screws and hang it on the wall, then you can connect the circuit, and the module must also use 35MM galvanized rails to install the module. On the guide rails, install the guide rails in the distribution cabinet.
Sixth, if there is no space reserved in many power distribution cabinets, and the lightning protection modules are not installed, they are generally equipped with lightning protection boxes outside the distribution cabinet. It is safe. If the modules are installed, it is not only unsightly but also very Easily affected by the external environment affect the quality.
So since the lightning protection box has so many advantages, why should we use any module and use the box directly? In fact, the module is still a little small advantage. First of all, in terms of price, the module is much cheaper than the box. After all, above the manufacturing cost, the manufacturing process has to be much smaller. Then, if there is enough space in the distribution cabinet and it is not easy to pull the outside line, it still uses the lightning protection module and is directly installed in the distribution cabinet. The distribution cabinet does not need to punch and pull out the cable, it will not affect the appearance, so many people still like the module.
Well, this is the difference between the lightning protection box and the lightning protection module. I hope everyone can read it and use it reasonably later. When using the lightning protection box, do not use the module to save money. If it is, then it will be based on savings, and the use of modules will do no harm.
