A kind of anti-bird device used on hanging insulator string

Abstract

The invention discloses a bird-prevention device used on a suspension insulator string. The bird-prevention device comprises a first fixed plate, a second fixed plate, a third fixed plate and a fourthfixed plate, wherein the first fixed plate, the second fixed plate, the third fixed plate and the fourth fixed plate are laminated from top to bottom and are connected to a pull rod of the insulatorstring by four arc clamps and bolts, an upper umbrella cover is fixedly connected onto an outer side edge of the first fixed plate and inclines downwards, a lower umbrella cover is fixedly connected to an outer side edge of the fourth fixed plate and inclines downwards, side edges of the upper umbrella cover and the lower umbrella cover are fixedly connected by an outer arc plate, an upper side cover is fixedly connected with an outer side edge of the second fixed plate and inclines downwards, a lower side cover is fixedly connected with an outer side edge of the third fixed plate and inclinesdownwards, and side edges of the upper side cover and the lower side cover are fixedly connected by an inner arc plate. By arranging the device above the suspension insulator string, the suspension insulator string can be effectively protected, bird guano is prevented from being discharged onto the insulator string, the phenomenon of circuit trip is prevented, and a good application effect is achieved.

Description

technical field [0001] The invention relates to an insulator, in particular to a bird-proof device used on a suspension insulator string, and belongs to the technical field of power transmission line equipment. Background technique [0002] With my country's emphasis on environmental protection, as well as the increase in forest coverage and the number of bird species, the flashover accidents caused by bird damage are on the rise. In actual work, in recent years, the health status of the equipment has been continuously improved through major repairs and technical renovations, and the defects in the stock of equipment have become less and less, but the hidden dangers of defects caused by external factors have become more and more, of which the largest proportion is The defects caused by birds account for more than 80% of the total defects. According to the grading requirements of the defect standard library of power transmission and transformation equipment, the honeycomb on...

Problems solved by technology

After many bird nests were cleared, new bird nests were found during the next on-site work (in some places, new bird nests were built within a month). Repeated processing is a lot of work, wasting manpower and material resources, and has a great impact on the normal operation of the line.

[0003] Birds generally build their nests on the tower above the insulator. When the birds move on the tower, they will discharge the guano on the insulator. Since the guano is a liquid excrement with conductive properties, it will cause damage to the line. tripping problem
