Abstract

The invention discloses a full coated disk-shaped porcelain (glass) composite shed insulator for a power transmission line, relates to a tension resistance string insulator for the power transmission line, and belongs to the technical field of power equipment. The insulator is provided with a silicon rubber shed, the hydrophobicity is good, the insulator has a hydrophobic mobility, an antifouling performance is improved, cleaning and maintenance are not required, the problem that a porcelain or glass insulator is fragile is solved, a shed interval is increased, performances of resistance to rain flashover, ice flashover, fog flashover and pollution flashover are improved, a shed is provided with a dripping edge, in the raining state, a dry area is effectively increased, and a wet withstand voltage level is improved, besides, a high temperature silicon rubber vulcanization silicon rubber shed is utilized, 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 fully-covered disk-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. Many power system experts, professors from Tsinghua University and many other colleges and universities have invested a lot of research. Experimental research in 2012 proved that thr...
