Bird repellent device for high-tension transmission line

Abstract

The invention discloses a bird repellent device for a high-tension transmission line. The device is arranged above an insulator chain, wherein the insulator chain is suspended at the position of a cross arm of a pole tower. The device comprises a bird repellent plate, wherein the bird repellent plate comprises a base plate and a metal net located on the base plate, the metal net comprises a main ground wire connecting wire, a main high-tension connecting wire, multiple ground wire sections and multiple high-tension sections, the ground wire sections and the high-tension sections are arranged alternately at intervals, one end of each ground wire section is connected with the main ground wire connecting wire, and one end of each high-tension wire section is connected with the main high-tension connecting wire. According to the device, the insulator distribution potential difference bird repellent method is adopted, birds can be hit by high-tension electricity after falling onto the bird repellent plate, and after multiple times of electric shock, conditioned reflex can occur on the birds to make the birds fear the bird repellent device.

Description

technical field [0001] The invention relates to the field of bird repelling for power transmission lines, in particular to a bird repelling device. Background technique [0002] Transmission lines have been running in the wild for a long time, and the line towers are favored by birds, and they have become places for birds to rest and stay, which has caused great harm to the line operation. Birds build nests, lay eggs, hatch on poles and towers, and move around with branches and straws in their mouths. It is very easy for these objects to fall between the cross arm and the wire, causing line failure. At the same time, when bird feces are blown to the wire by the wind and accumulate on the shed or cross arm of the insulator, it will cause pollution flashover of the insulator, air gap discharge, breakdown or short circuit to ground.

AI Technical Summary

Problems solved by technology

Birds build nests, lay eggs, hatch on poles and towers, and move around with branches and straws in their mouths. It is very easy for these objects to fall between the cross arm and the wire, causing line failure

At the same time, when bird feces are blown to the conductor by the wind and accumulate on the shed or cross arm of the insulator, it will cause pollution flashover of the insulator, air gap discharge, breakdown or short circuit to ground accidents

[0003] In order to reduce the threat of birds to the line, the current common bird-proof measures include bird-proof covers, bird-proof thorns, high-frequency sound-wave bird-proof devices, etc., but the effect is not particularly ideal

The anti-bird cover can prevent the damage of bird droppings to the insulator, but it is affected by the wind, has poor stability and is easy to fall off; the anti-bird thorn can prevent birds from staying on the tower, but its protection range is small. If the thorn is too long, it will easily cause damage to the wire. The air gap is not enough, which will hinder the online operation of the maintenance personnel, and it is inconvenient to install; the high-frequency sound wave anti-bird device cannot drive away all the birds due to the strong directionality and fast attenuation of the ultrasonic wave itself, and the large difference in the induction of different birds. Birds, the ultrasonic waves emitted worsen the living environment of birds, causing harm to birds, and its anti-bird effect is not good
