Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a lightning arrester which is convenient to install. Background Art

[0002] Lightning arresters are also known as lightning protectors, surge protectors, surge protectors and overvoltage protectors. They mainly include power lightning arresters and signal lightning arresters. They use modern electrical and other technologies to prevent damage to equipment struck by lightning. They are used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time, and often also limit the current amplitude.

[0003] As shown in the announcement number CN 211930234 U, a lightning arrester that is easy to install is disclosed, including a lightning arrester body and a base plate. A plurality of inclined grooves are arranged inside the base plate, and the plurality of inclined grooves are parallel to each other. A transverse groove connected to the inclined groove is arranged at the bottom of the base plate, and a pushing cylinder is arranged at one end of the transverse groove. The device does not have a simple press-type disassembly mechanism, and the lightning arrester cannot be separated from the chassis column by light manual pressing. When the lightning arrester is damaged, cumbersome replacement is required, which is time-consuming and labor-intensive. At the same time, there is no accompanying positioning and supporting mechanism, which greatly reduces the overall safety and stability of the device. This makes the lightning arrester likely to fall down when subjected to external forces, and the practical value is not high. Utility Model Content
