Embodiment 1

[0017] The invention discloses a semi-covered disk-shaped porcelain (glass) composite shed insulator for power transmission lines, which is composed of a steel cap, a porcelain insulator, a silicon rubber composite shed, and a steel foot. The steel cap is located on the upper part of the center of the porcelain insulator, and the silicone rubber composite shed is tightly fitted on the porcelain insulator shed. The edge of the silicone rubber shed is 10-30 mm higher than the porcelain insulator shed. The silicone rubber shed forms an effective water-repellent The pitch is 200-420mm, accounting for 40%-90% of the creepage distance of the original porcelain insulator, and the steel foot is located below the center of the porcelain insulator. Porcelain insulators are composed of adhesives with high strength and excellent insulation properties. Its composite shed is made of high-quality silicone rubber compound and vulcanized in a mold under high temperature and high pressure; the ...

Abstract

The invention relates to a half coated disk-shaped porcelain (glass) composite shed insulator for a power transmission line and belongs to the technical field of power equipment. The insulator comprises a steel cap, a porcelain insulator, a silicon rubber composite shed and steel legs. Creepage distance of hydrophobicity is increased, and the problem that a porcelain or glass insulator is fragile is solved. A shed interval of the porcelain or glass insulator is improved, an electro erosion of a high electric field area on the end portion of the porcelain or glass insulator to a composite material, a steel horn and the steel cap is prevented, and a lightning resistant performance is improved. A dry area is effectively increased, and a wet withstand voltage level is improved. The problems that the room temperature vulcanized silicon rubber (RTV) coating painted on a tension resistance porcelain (glass) insulator is prone to fall off and the service life is short are solved, and the construction safety potential risks are prevented.

Description

technical field [0001] The invention discloses a semi-covered disc-shaped porcelain (glass) composite shed insulator for power transmission lines, relates to an insulator for tension strings for power transmission lines, and belongs to the technical field of electric equipment. Background technique [0002] Composite insulators have been rapidly popularized in power grids since around 1997 due to their light weight, high pollution and humidity resistance, and maintenance-free characteristics. However, other types of insulators (porcelain, glass insulators, etc.) coexist in the same line, which cannot completely solve the problems of line cleaning and pollution flashover. At present, spraying RTV or PRTV is mostly used, which has a short service life and cannot fundamentally solve the problem. Experts from China Electric Power Research Institute, professors from Tsinghua University and many other colleges and universities have invested a lot of research. Experimental resear...
