Technical Field

[0001] The utility model belongs to the field of power supply lightning arresters, in particular to a power supply lightning arrester device with multiple safety protection functions. Background Art

[0002] A power surge arrester, also known as a lightning arrester, surge protector, or surge protector, is a multiple safety protection device used to protect electrical equipment from damage caused by lightning overvoltage and overvoltage within the power system.

[0003] In the prior art, in order to ensure the normal operation of the power lightning arrester, it is usually necessary to perform regular maintenance on the power lightning arrester. When it is necessary to inspect the accessories inside the power lightning arrester, the outer shell needs to be removed from the device, but the outer shell and the device are usually connected with screws. Therefore, in the process of disassembling and assembling the outer shell, it is necessary to use suitable screwdrivers and other tools for assistance. Moreover, after the screws are removed, if they are not uniformly stored in time, the screws may be lost due to their small size. If the screws are accidentally lost, it may affect the subsequent connection between the outer shell and the device. For this reason, we provide a power lightning arrester device with multiple safety protection functions to solve the above problems. Utility Model Content
