The protection process of the customized lightning arrester

The customized lightning arrester is a very common equipment component in the power system. It is installed between the incoming and outgoing wires and the ground wire to play the role of overvoltage protection. Therefore, the customized lightning arrester is also called "overvoltage protector". The damage caused by the impact of overvoltage plays a key role.
When the customized lightning arrester is used at different voltage levels, the size is different, but the composition structure is basically the same. It is composed of silica gel group sleeve, metal terminal, ZnO valve plate, polymer filling material, epoxy mandrel, hanging ring, epoxy glass steel cylinder and plated Composed of copper flanges.
The protection process of the customized lightning arrester:
The main element for protection in the arrester structure is the zinc oxide valve plate, which has good volt-ampere characteristics. It is in a high-resistance state during normal operation. When there is an impact voltage intrusion, the current flowing through the valve plate increases rapidly, forming In the open state, the overvoltage is released, and then the zinc oxide valve returns to the high resistance state to maintain the normal operation of the power system.
The main factors affecting the customized lightning arrester:
1. The rationality of the overall structure of the customized lightning arrester;
2. Volt-ampere characteristics and aging resistance characteristics of zinc oxide valves;
3. The sealing performance of the customized lightning arrester.
