Abstract

The invention belongs to the technical field of power equipment, in particular to a high-voltage anti-pollution flashover anti-vacuum flashover insulator and a preparation method thereof. The insulator comprises a fluorinated polymer matrix, oxide particles uniformly dispersed in the fluorinated polymer matrix and a photocatalyst film uniformly covering the surface of the fluorinated polymer matrix, wherein holes are uniformly dispersed in the surface of the fluorinated polymer matrix, the holes are formed by removing oxide particles on the surface of the fluorinated polymer matrix through corrosion by adopting an inorganic acid chemical corrosion method, the material of the oxide particles is an oxide which is easily dissolved in an inorganic acid, and the photocatalyst film is a TiO2-SiO2 composite photocatalyst film. The holes which are evenly distributed are manufactured in the surface of the fluorinated polymer insulator, the surface breakdown voltage of the insulator is improved,the vacuum flashover phenomenon is reduced, the photocatalyst film covers the fluorinated polymer insulator, the purposes of reducing the pollution degree and pollution speed of the insulator and prolonging the service life of the insulator are achieved, and the anti-pollution flashover performance of the insulator is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a high-voltage anti-pollution flashover vacuum flashover insulator and a preparation method thereof. Background technique [0002] Insulators are important external insulation equipment for high-voltage transmission lines and substations. If the insulator is used outdoors for a long time, a large amount of solid, liquid and gaseous pollutant particles will inevitably be deposited on its surface. It is greatly reduced. Under the action of overvoltage, partial arc discharge occurs, and then pollution flashover occurs, resulting in accidents such as tripping and power failure, and its economic loss is very alarming. The traditional method of preventing pollution flashover is to install RTV (PRTV) coating on the outer layer of insulators. RTV coating is a solid coating with excellent performance, and RTV coating has good hydrophobic migration performance...
