No-blind-zone bird repellent device and cross arm for pole and tower of high-tension transmission line

Abstract

The invention discloses a no-blind-zone bird repellent device and a cross arm for a pole and tower of a high-tension transmission line, and aims to solve the problem of poor bird repellency of a transmission line. The no-blind-zone bird repellent device can effectively repel birds around the pole and tower of the transmission line, ensures that the birds cannot build nests or defecate within a bird-repellent thorn protection range, prevents the birds from lingering or building nests on the pole and tower of the transmission line, and has a very good bird repellent effect. The technical scheme is that the no-blind-zone bird repellent device comprises a connecting base, wherein a fixed plate is arranged at the top of the connecting base; the top of the fixed plate is connected with a fixed block; the top of the fixed block is connected with a bird repellent thorn group; a pointed thorn group is further arranged at the side part of the fixed block; and anti-blind-zone oblique thorns are arranged at the lower part of the bird repellent thorn group.

Description

technical field [0001] The invention relates to the technical field of protective equipment for high-voltage transmission lines, in particular to a bird-repelling device and a cross-arm without blind areas for high-voltage transmission line poles and towers. Background technique [0002] In recent years, with the improvement of the ecological environment and the enhancement of human awareness of wildlife protection, bird activities have become more frequent. When birds defecate, nest, fly, peck and other activities on the transmission line, the excreted bird droppings form a conductive channel, which may cause the air gap breakdown of the tower, and the insulator may also have flashover and other problems. A large bird will directly cause a short circuit fault, seriously affecting the safe and stable operation of the transmission line. From 2005 to 2014, a total of 1867 trips due to bird damage occurred on 110 (66) kV and above lines of the State Grid Corporation of China, ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a high-voltage transmission line tower without blind zone bird repelling device, which can effectively prevent birds from nesting and excreting on the transmission line, and improve the reliability of transmission line operation. The present invention solves the problem of Eliminate the blind area of ​​bird thorns, make the bird thorns truly realize the anti-bird function, and avoid bird damage accidents on power transmission lines;

The bird-repelling device of the present invention is provided with a bird-repelling thorn group on the top, so that the top forms a bird-proof area; a spike group is arranged on the side, so that the side forms a bird-proof area; an anti-blind area oblique thorn is set at the bottom of the bird-repelling thorn group, so that The lower blind area of ​​the bird-repelling thorn group also has the function of preventing birds; thus, the combination of the bird-repelling thorn group, the sharp thorn group and the oblique thorns in the anti-blind area makes the device have an anti-bird effect in all directions, which solves the problem of the bird thorn blind area. The bird thorn truly realizes the anti-bird function and avoids bird damage accidents on power transmission lines
