An anti-rat and snake device for distribution lines

Abstract

The invention discloses a rat and snake prevention device for a power distribution line. The device comprises an upper insulating cover and a lower insulating cover, wherein the upper insulating covercomprises an upper insulating shell and an upper insulating tube, and openings are respectively formed in the lower end, the left end and the right end of the upper insulating shell; the upper insulating tube is arranged horizontally, and the left end of the upper insulating tube is connected with the opening in the right end of the upper insulating shell; the lower insulating cover comprises a lower insulating cylinder with upper and lower end openings and an insulating shed fixed at the bottom of the lower insulating cylinder; the upper end opening of the lower insulating cylinder is connected with the lower end opening of the upper insulating shell. According to the rat and snake prevention device for the power distribution line, the exposed part of a rod tool can be subjected to fullinsulating treatment effectively and comprehensively, and accordingly, external force damage caused by rats, snakes and the like is prevented fundamentally.

Description

technical field [0001] The invention relates to a rat snake prevention device for distribution lines. Background technique [0002] External force damage to distribution lines at home and abroad has always been an unsolved problem for many years. Among them, a large part of the external failure is caused by the short circuit of the line caused by the climbing of rats and snakes. With the increase in the number of breakage accidents and the expansion of the scope of influence, the breakout problem of distribution lines has attracted enough attention. [0003] For transmission and distribution lines, anti-rodent snakes are currently traditional protective measures, mainly anti-snake thorns and bird repellent devices, and there is no effective solution for anti-rats. As the protection of the green environment is strengthened, the probability of rat snakes appearing will increase. The general anti-snake device mainly relies on anti-snake thorns to prevent snakes from climbing...

AI Technical Summary

Problems solved by technology

Therefore, the anti-snake stabbing device has not fundamentally solved the problem of external breakage caused by the climbing of rat snakes, and there are great difficulties in designing insulation measures for the exposed part of the pole knife head. The key components of the pole knife installed on the line must "guarantee the conductive element There are reliable ground insulation, support insulators that can withstand the operating force of conductive elements and various external forces", but the insulation distance of the exposed part of the current pole cutter head is only 170mm, which is obviously lower than the 200mm dry arc distance. Affect the normal operation of the line, but as long as there is a little foreign matter (such as rat snakes, branches, etc.), it is easy to cause the insulation distance to shorten, resulting in insulator flashover and tripping of the line. The seat is rotated to open and close, and the conductive contact part can be fixed. It is the best solution to design a personalized insulating cover to cover and insulate the conductive exposed parts such as the pole knife.
