Bird-proof needle plate for transmission line

Abstract

The invention discloses a bird preventing needle plate of an electric transmission line. The bird preventing needle plate comprises a lower-layer insulation plate and an upper-layer insulation layer stacked mutually and fixedly connected with each other, wherein a plurality of bird preventing needles are vertically arranged on the board of the lower-layer insulation plate; U-shaped stop bases are fixed on the board of the upper-layer insulation plate; the opening directions of the U-shaped stop bases are perpendicular to the length directions of the bird preventing needles. The bird preventing needle plate of the invention is mounted above an insulator, uses the sharpness and coverage area of the bird preventing needles to force birds to not stop or even nest in the dangerous positions of towers to achieve the bird expelling purpose, and can be operated for a long time; an insulation base avoids possible short-circuit hidden dangers when dropping.

Description

[0001] Technical field: [0002] The invention relates to a bird-proof pin plate for power transmission lines. [0003] Background technique: [0004] The towers of transmission lines are tall and stable, and many birds like to build nests and breed on them. Bird nests are often built in dangerous positions such as the suspension points of the tower insulator strings and the oblique intersections above the jumpers. When the following three situations occur, it will cause a line trip accident: (1) The nesting materials such as branches and iron wires sag or fall, and the insulator strings are short-circuited, and such faults are not easy to find; (2) Birds perched on the top of the tower Such feces fall to pollute the insulators, reduce the insulation level of the line, and accumulate to a certain extent to cause flashover, or short-circuit all or part of the insulators instantly when the feces fall. The frequency of such accidents is the highest; Take up the activity and sprea...

Problems solved by technology

Powered by solar energy, once it senses the approach of birds, it will emit a warning sound to stimulate the birds to achieve the purpose of repelling birds. However, after using it for a period of time, the birds gradually get used to the warning sound, and it loses its effect

In addition, increasing the insulator umbrella group, manually climbing poles to remove bird nests, etc. are also anti-bird measures. Although the above-mentioned methods have their own characteristics and have played a certain role, they all have certain drawbacks and cannot effectively prevent them. The occurrence of bird damage
