Anti-lightning Ability Of Coaxial Arrester

Sep 08, 2017




The coaxial arrester has a 10A current capacity. Its ability to prevent lightning strikes, high-frequency characteristics of good, lightning surge voltage relief is fast, is the common cable monitoring system, cable TV network security of effective protection devices, Coaxial Lightning Arrestor suitable for all two-way coaxial cable network online use.

The coaxial arrester is used to protect all kinds of electrical equipment in power system from Lightning Over-voltage, over-voltage, and transient over-voltage shocks. The type of coaxial arrester mainly includes protection clearance, valve type coaxial arrester and zinc oxide coaxial arrester. Coaxial Lightning Arrestor Protection gap is mainly used to limit atmospheric overvoltage, generally used in distribution systems, lines and substations to protect the line. Valve coaxial arrester and zinc oxide coaxial arrester for substation and power plant protection, in the 500KV and the following systems are mainly used to limit atmospheric overvoltage, in ultra-high pressure systems will also be used to limit the internal over-voltage or the back-up protection of the internal over-voltage.

Coaxial arrester performance Characteristics:

1, the impact of the number of shocks, determine the service life of the coaxial arrester, Coaxial Lightning Arrestor gas discharge tube after a period of time after the performance will not drop, unless the leak. To detect its good or bad, you can use a tunable high-voltage DC power test, or coaxial arrester tester.

2, reaction time, determine whether the coaxial arrester can be timely response, rapid release.

3. Insertion loss refers to the influence of coaxial arrester on the line, basically from these three indicators to judge good or bad, arrester and protected electrical equipment is a parallel relationship, Coaxial Lightning Arrestor if the arrester depends on the electrical equipment very near (set electrical distance l=0), then lightning when the voltage on the electrical equipment equals the residual voltage arrester, that is, u equipment = u residual-avoid, Coaxial Lightning Arrestor residual pressure lower u equipment charged lower, the more secure.

Coaxial arrester function and performance characteristics of the first for everyone to introduce here, read the above content, presumably to your help is not small, Coaxial Lightning Arrestor if there is nothing to understand the problem, can enter our official website for viewing.
