How to avoid pollution flashover accidents of insulators is one of the problems to be solved urgently in the current power system. Flashover refers to the destructive discharge of a gas or liquid medium along an insulating surface under high voltage. The types of insulator flashover are mainly pollution flashover, rain flashover, ice flashover, lightning flashover and operational flashover. The pollution flashover is pollution substances with conductive performance accumulated on the surface of the insulator, so that the insulation level of the insulator is greatly reduced after the insulator is affected with damp in humid weather, and flashover accidents occur under normal operation.
