Background

The transformer substation framework is a supporting structure of a transformer substation inlet wire, a transformer substation outlet wire and an internal lead, and is an important line pivot structure of the transformer substation.

The support structure of the circuit pole tower is favored by birds, becomes a place for birds to rest and stays, and causes great harm to circuit operation. Birds nest, spawn and hatch on the towers and run with branches and straws, so that the objects are easy to fall between the cross arms and the wires, and line faults are caused.

Meanwhile, when the feces of birds are blown to the wires by wind and accumulated on the umbrella skirt or the cross arm of the insulator, pollution flashover, air gap discharge, breakdown or short-circuit to ground accidents of the insulator can be caused.

In order to reduce the threat of birds to lines, the current common bird prevention measures of the transformer substation comprise bird prevention covers, bird thorns, high-frequency sound wave bird prevention devices and the like, however, the bird prevention modes have various advantages and of course have various disadvantages.

The bird prevention cover can prevent damage of bird droppings to the insulator, and the bird thorn type bird prevention cover is adopted in the Chinese patent application No. CN201320255859.8, and the bird thorn is added on the bird prevention cover, so that the bird prevention function is increased on the basis that the bird prevention cover originally blocks the droppings. However, bird scaring thorns tend to cause insufficient air gap to the wires and, according to practice, birds are very adaptable, and after a period of time of bird scaring thorns, some bird nests can be built directly on bird scaring thorns, which in turn can prevent maintenance personnel from working online.
