Abstract

The invention discloses a superhydrophobic coating, an anti-pollution-flashover superhydrophobic insulator and a preparation technique thereof. The superhydrophobic coating comprises a finishing coat arranged on the external surface of the insulator and the superhydrophobic coating arranged on the finishing coat. The finishing coat is prepared from a surface modification solution which is composed of a surface modifier propyltrimethoxy silane and ethanol in a mass ratio of 1:(5-20), and the superhydrophobic coating is prepared from a nano silicon dioxide superhydrophobic paint. The anti-pollution-flashover superhydrophobic insulator comprises an insulator body and the superhydrophobic coating applied to the external surface of the insulator body. By setting the reaction temperature in the finishing coat application process and the pressure, angle and other parameters in the superhydrophobic coating spraying process, the obtained anti-pollution-flashover superhydrophobic insulator has the advantages of long service life, high aging resistance and excellent hydrophobicity, can effectively reduce the filth accumulation volume on the insulator surface under haze and heavy dirt conditions, has higher pollution flashover resistance, and ensures the long-term reliability of the electric system external insulation.

Description

technical field [0001] The invention relates to the technical field of high-voltage external insulation, in particular to a superhydrophobic coating used for insulators in haze weather, an anti-pollution flashover superhydrophobic insulator and a preparation process thereof. Background technique [0002] With the rapid development of industry and urban population in our country, the problem of air pollution is becoming more and more serious. In recent years, smog weather has appeared on a large scale in my country. The air pollution caused by smog has brought many hazards to people's production and life, and it has also brought adverse effects on the power system. Pollution flashover accidents caused by smog weather have occurred frequently, reducing the The operation reliability of the power grid is easy to cause large-scale power outages. Therefore, there is an urgent need to study the anti-pollution flashover problem of power systems in haze weather. [0003] Smog contai...
