Description

Antifouling insulator suitable for long rainy season area

Technical Field

The invention relates to the field of insulators, in particular to an antifouling insulator suitable for long rainy season areas.

Background

The insulator is a special insulating control and can play an important role in an overhead transmission line. Early-year insulators are mostly used for telegraph poles, and a plurality of disc-shaped insulators are hung at one end of a high-voltage wire connecting tower which is gradually developed, are used for increasing creepage distance and are usually made of glass or ceramics, namely insulators. The insulator should not fail due to various electromechanical stresses caused by changes in environmental and electrical loading conditions, otherwise the insulator will not function significantly and will compromise the service and operational life of the entire line.

Insulator fouling can cause flashover and power failure. Various countries adopt different methods for sweeping sewage, including brushing and flushing. The main flushing methods include a hand-held spray gun method, helicopter water spraying, robot remote control spray gun and fixed water gun flushing. The cleaning method has the advantages that the insulator is cleaned in an insulating and maintaining and electrified mode, various comprehensive pollutants such as static electricity, dust, oil stain, salt, carbon stain, acid and alkali gas, charged particles and the like can be rapidly and thoroughly removed, and corrosion of the insulating layer is reduced. And protecting the anti-pollution flashover layer. After the serious pollutants on the insulator of the power transmission and transformation equipment are cleaned in time, the large-area sudden power failure accident caused by pollution flashover and fog flashover can be prevented.

The existing insulator cleaning method needs to waste a large amount of manpower resources for cleaning on the spot, and also needs cleaning personnel to have enough corresponding professional knowledge, so that accidents are avoided in the process of cleaning the insulator in a charged manner, and the cost for cleaning the insulator is further increased.
