To investigate the corona aging characteristics of high-temperature vulcanized silicone rubber under different environmental stresses, this paper simulates a fog-haze environment in the laboratory and establishes a platform for testing corona aging. The silicone rubber samples are subjected to corona discharge under haze, salt fog, and fog-haze environments for different durations. The characteristics of silicone rubber after aging are studied from the surface microstructure. The longer the aging time, the more serious the sample aging, and the pollutants in the environment will gradually adsorb around the aging area while gradually covering the surface of the sample. Different haze conditions have similar effects on the corona aging of silicone rubber, which will cause cracks and particles on the surface of silicone rubber. However, corona aging has different effects on the aging rate of silicone rubber surface under different haze environments. Sodium nitrate salt fog environment and fog-haze environment are relatively fast. The research results can be used to evaluate the haze-prone areas and provide reference for composite insulators in anti-haze and anti-pollution flashover.
