Abstract

The utility model relates to an electric and power device provided with an outer insulating layer, in particular to an electric and power device with a silicon-fluorine rubber-PRTV outer insulating layer. The outer surface of the electric and power device before leaving the factory or after installation adopts room temperature vulcanized silicon-fluorine rubber-PRTV outer insulating layer which is processed and formed by spray painting, brushing or dip coating methods. The utility model has superior hydrophobic nature, high dielectric strength, high insulating property, anti-ultraviolet performance, anti-erosion property, long service life, and improved anti-contaminant flashover ability.

Description

Electric, power equipment that external insulation organises

(1), technical field

The utility model relates to a kind of electric, power equipment that external insulation layer is arranged, and electric, the power equipment of fluosilicic rubber-PRTV external insulation layer particularly arranged.

(2), background technology

Present electric, power equipment are that insulating material is made with porcelain, glass, fiberglass mostly, because under certain external condition as humidity, dirt etc., these materials present very strong hydrophily, so greatly reduce the external insulation ability, cause easily taking place pollution flashover accident.

(3), summary of the invention

In order to overcome the shortcoming of prior art, electric, power equipment that the utility model provides a kind of external insulation to organise, it not only has good hydrophobicity, the dielectric strength height, insulation property height, and UV resistant, anti-erosion, long service life has improved its anti-pollution flashover ability greatly.

The technical scheme in the invention for solving the technical problem is: the room temperature vulcanization add-on type fluosilicic rubber-PRTV external insulation layer that adopts spraying, brushing or dip-coating method to be processed to form on the outer surface of electric, the power equipment behind dispatch from the factory preceding or the installation and operation.

Described electric, power equipment can be high-tension insulator, low tension insulator, suspension insulator, pin insulator, dish formula insulator, post insulator, cross arm insulator, straight excellent insulator, bushing, circuit breaker, instrument transformer, coupling capacitor, trap, the reactor made from porcelain, glass, fiberglass or plastics, and rated voltage is 1～750kV.

The utility model is compared with the external insulation of prior art has following advantage: 1, good hydrophobicity and fast, balanced, migration of hydrophobicity enduringly, the resistant lightning is pressed and is improved more than the twice; 2, dielectric strength is up to 30MV/m, and electric erosion resistance reaches the TMA4.5 level, arc resistant, and anti-flammability reaches the FV-0 level; 3, mechanical strength height, adhesive force is good, acid and alkali resistance, salt and chemical mediator corrosion, oil resistance is good; 4, UV resistant, ozone, the opposing environmental attack, non-scale does not ftracture, and reaches useful life more than 20 years; 5, surface energy is low, and from clean good, conventional maintenance is exempted from cleaning in the phase, satisfy electric, power equipment is antifouling, the needs of moistureproof, insulation technology.
