Abstract
The utility model provides a kind of antifouling flash insulator, comprises insulator body, is located at the coating of insulator surface, it is characterized in that: insulator surface coating is aqueous polyurethane coating.Its technical scheme is through silane coupler modified aqueous polyurethane coating at glass insulator surface-coated one deck.There is good filming performance, stronger covering power and firm, reliable adhesive property and hardness, insulator is made to have excellent mechanical performance, weather resistance, water resistance, resistance to chemical corrosion, effectively can improve the hydrophobicity performance of insulator surface, reduce filthy deposition, reduce pollution flashover odds, ensure electric power netting safe running.
Description
Technical field
the utility model relates to a kind of antifouling flash insulator, belongs to electrical equipment technical field.
Background technology
Insulator, in the power distribution equipment of power plant and transformer station, is used for supporting and fixing current－carrying conductor, and makes insulating between phase and phase and between phase and ground of current－carrying conductor.Therefore, require that insulator should have enough dielectric strengths and mechanical strength, and can safe operation under rugged environment is as high temperature, humidity, many dust, dirt.Usually, the insulator of on-line operation is in atmospheric environment mostly, surface can deposit one deck dunghill gradually, when running into wet weather, solable matter in dunghill can water-soluble and formed conduction moisture film, so just have leakage current to flow through along insulator surface, the size of current flow through depends primarily on degree of fouling and damp degree.When dirty and make moist more serious time, local arc can progressively develop, and when meeting or exceeding critical condition, electric arc can run through the two poles of the earth, formed pollution flashover, be called for short pollution flashover.Once insulator produces pollution flashover, serious threat can be brought to the safe operation of electric power system.At present, the precautionary measures for insulator contamination mainly contain: increasing insulator creepage distance, enforced insulator surface hydrophobic performance, human at periodic intervals clean, and the subject matter that these measures exist has: 1. the problem that fundamentally can not solve dunghill deposition; 2. cost is higher.Adopt the way of coating silicon rubber to insulator surface in prior art, but silicon rubber is elastic material, easy attract dust, and when the insulation property reduction of insulator, people usually can not Timeliness coverage, easily causes major accident under severe conditions.
Summary of the invention
For overcoming prior art above shortcomings, the utility model provides a kind of antifouling flash insulator with excellent water resistance, weatherability, resistance to chemical corrosion.
The utility model realizes the technical scheme that above-mentioned purpose adopts: a kind of antifouling flash insulator, comprises insulator body, is located at the coating on insulator body surface, it is characterized in that: the coating of insulator surface is aqueous polyurethane coating.
Described aqueous polyurethane coating thickness is 5 ~ 20 μm.
Described aqueous polyurethane coating applies completely along outer surface of insulator and inner surface.
Described aqueous polyurethane is commercial through silane coupler modified aqueous polyurethane.
The beneficial effects of the utility model are: adopt such scheme, namely after outer surface of insulator and inner surface apply aqueous polyurethane completely, because having good filming performance, stronger covering power and firm, reliable adhesive property and hardness, insulator is made to have excellent mechanical performance, weather resistance, water resistance, resistance to chemical corrosion, effectively can improve the hydrophobicity performance of insulator surface, reduce filthy deposition, reduce pollution flashover odds, ensure electric power netting safe running.
