what are the types of lightning arrester?

There are multiple classification methods for lightning arresters,

It can be divided into AC surge arrester and DC surge arrester according to the voltage type of the power grid. According to different protection objects of DC surge arresters in converter stations, they are divided into surge arresters for DC side protection, surge arresters for AC side protection, surge arresters for flat wave reactor protection, surge arresters for bridge valve protection, etc.

According to different uses of lightning arresters, it can be divided into power station type arresters, distribution type arresters and special purpose arresters (such as surge arresters for compensation capacitor banks, etc.).

what are the types of lightning arrester

According to the different working conditions of the arrester, it can be divided into normal use condition type arrester, high prototype arrester, pollution-resistant arrester, tropical arrester and so on.

According to the material of the arrester shell, it can be divided into ceramic arrester, silicone arrester and iron arrester. According to the working principle of the arrester, it can be divided into protective gap, tube-type arrester, valve-type arrester (including ordinary valve-type arrester and magnetic blowing valve-type arrester) and metal oxide arrester (zinc oxide arrester). Protective gaps and tube-type arresters are mainly used to limit lightning overvoltage, and are generally used for the protection of the incoming line section of power distribution systems and substations. Valve-type arresters and zinc oxide arresters can be used for overvoltage protection in power plants and substations. Among them, ordinary valve-type arresters are mainly used to limit lightning overvoltage. To limit internal overvoltage.
