Embodiment Construction

[0029] See Figure 4- Image 6 As shown, first, the relationship between the particle size of the experimental filler and the leakage current. Suspend the ceramic insulator in the salt spray test chamber and apply 10KV (400V / cm) energy. The salt spray comes from vaporized salt water, and its conductivity is 250μS / cm. The leakage current is monitored by the data collection system.

[0030] refer to Figure 5 As shown, it is a diagram of the variation of the ceramic surface leakage and the particle size of the three-water bauxite filler. The insulator is suspended on the surface of the ceramic insulator coating by passing through the above-mentioned 400V / cm under the filler with different average sizes varying from 1-13μm. The relationship between the time required for leakage current to occur and the average particle size of the bauxite trihydrate filler;

[0031] The particle size of SU-101 is 4.5μm, and its leakage time will occur within 100 hours;

[0032] The particle siz...

Abstract

A high-voltage insulating composite paint for the high-voltage (69 KV or more) insulator is prepared from polydimethyl siloxane, dried trihydrated alumina, dye cream, filler, organosilicon cross-linking agent, adhesion promoter, condensating catalyst and dried hydrocarbon solvent. It can suppress electric leakage and spark.

Description

technical field [0001] The present invention relates to a composition of high-voltage insulator coating and its preparation method and application. It uses a room-temperature-hardening type organopolysiloxane rubber composition, and carries out cross-linking reaction at normal room temperature. Form a protective layer on the surface of the object, which can improve its electrical properties. Background technique [0002] As we all know, traditional high-voltage insulators are generally made of porcelain and glass, and porcelain and glass are easy to produce any shape of the appearance of the insulator. Electrical stress and leakage can have a long service life, but if it is polluted, in order to prevent excessive leakage, it is necessary to clean or coat a layer of silicon-like compound frequently, so insulator pollution has become a power The main obstacle to continuous supply. In terms of glass and ceramic insulators, they are often used in power systems. When wet weather...
