Suppression Measures of Insulator Flashover Caused by Haze Flashover

Fog haze weather frequently appears in recent years. Fog haze not only makes the travel inconvenient, also has a harmful effect on body. Fog haze brings serious security hidden danger to the power grid safety and power equipment operation. The lightest situation is shortening the time of saturated salt density, and pollution accident is the heaviest situation caused power equipment. The concept of haze flashover, haze and PM2.5 is explained, and the harm and source of haze are expounded. At the same time, the mechanism of haze flashover and the measures to restrain haze flashover are discussed. It is pointed out that the best method to prevent haze flashover is dry ice cleaning, and dry ice cleaning is the implementation technology to ensure the safe operation of power equipment in the future, which has a wide application prospect.
