How To Be Called A High-quality Surge Protector, These 3 Points Must Be Met
At present, a large number of people think that surge protectors are just switching components, and often ignore their functions. When buying them, they often buy them wherever they are cheap. However, you should know that there are major mysteries behind this small component. After reading this chapter, you will understand.
According to relevant statistics, fires caused by electrical reasons in my country are ranked first, accounting for about 26.6% of the total number of fire accidents. Here are some cases:
1. On July 3, 2014, the SPD of the new office building distribution box in Wangcheng, Hunan caught fire.
2. In February 2012, the surge protection device of four communication base stations in Xi'an caught fire, and the claim was more than 6 million yuan.
So the small surge protective device in the distribution box actually has an irreplaceable role!
So what kind of surge protector is good? Only those that meet the following 3 requirements are high-quality surge protectors!
1. When the surge protector is aging, the internal mechanism can be tripped in time (SPD does not catch fire), and it will not trip during lightning strikes (lightning protection is continuously effective).
2. The internal process is rigorous and can work continuously and stably in any harsh working environment.
3. The product consistency should be good! In the same set of products, the indicators of each P surge are consistent (such as the up/uc/in/imax parameter values of the MOV chip).
The consistency of point 3 is especially important! Assuming a 4P surge protector, where the UC value of 1P is much lower than that of the other 3P, then when the lightning current comes, it will be hit harder, and it will bear most of the overvoltage every time, causing it to deteriorate rapidly, and the product will be out of service in a short period of time. On the contrary, if the parameters of 4P are consistent, then when the lightning current comes, everyone will benefit equally, so the product will have a longer service life and more stable performance!
