Abstract

The invention discloses a lightning arrester grounding device convenient to maintain. The grounding device comprises a grounding rod, and the lower end of the grounding rod is welded with an insulatedcase. The grounding rod and the case are buried in the ground together; a scraper ring is arranged on the portion, buried in the ground, of the grounding rod around a shaft, a cylindrical box is welded to the box wall of the top of the case, the box wall of the upper portion of the cylindrical box penetrates through the box wall of the case to make contact with the bottom end of the grounding rod, and a piston plate is connected to the inner wall of the cylindrical box in a sealed and sliding mode. Evaporated liquid on the piston plate in the device is heated and vaporized to push the pressing plate to slide downwards to drive a threaded shaft disc to rotate; due to the fact that the disc is provided with the groove and the protruding block, when the lower end of the thick rod and the lower end of the thin rod make contact with the groove and the protruding block, the whole thick rod and the whole thin rod vibrate, the scraper ring is driven to vibrate to scrape off an oxide layer onthe grounding rod, and the grounding device has the self-maintenance function.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a grounding device for a lightning arrester which is convenient for maintenance. Background technique [0002] For the current lightning arrester grounding device, a fixed metal rod is generally used, generally made of copper rod, iron rod or alloy rod, which is directly inserted into the ground, and its upper end is connected to the lightning arrester. Due to the harsh underground environment, it is easy to oxidize the surface of the grounding rod and increase the grounding resistance. If this problem is not dealt with in time, the arrester will not be able to protect the electrical equipment normally when a lightning strike occurs. After oxidation, it must be pulled out for repair, or directly replaced with a new grounding rod, and the maintenance cost is high. [0003] Although some existing lightning arrester grounding devices have oxide layer removal funct...
