Description

Anti-bird insulator for transformer

Technical Field

The invention relates to the technical field of power insulation equipment, in particular to an anti-bird insulator for a transformer.

Background

The insulator is a supporting component commonly used for an electric power transmission line, especially, a porcelain insulator is usually arranged at the top of a transformer to play an insulating role, the bird damage of the insulator is a great threat to the bird dung flashover caused by bird residence in the working process, if bird dung flashover is caused by bird dung residence, the accidents are increased in recent years, one is the flashover caused by the fact that the bird dung falls on the insulator, the surface of the insulator has obvious bird dung marks, the other is that the bird dung falls along the outer side of the grading ring but close to the grading ring, short circuit discharge between upper and lower fittings is directly caused, and the bird dung marks are not left on the insulator.

Therefore, it is very important to prevent birds from standing on the top of the porcelain insulator for a long time, the top of the existing porcelain insulator is usually in a tip shape, but the tip shape can scratch the claws of the birds when the birds stand for a short time, so that parts of endangered birds are injured or even die, adverse effects are generated on the ecological environment, and certain defects exist because the top of the porcelain insulator is only arranged to be an arc-shaped surface and cannot be used for well driving the birds.
