| Abstract: | This paper introduces corona electric field is produced by spininess-pin-to-flat electrode model,under the lab condition,with simulated high-altitude region low air pressure,and silicone rubber composite insulator samples are aginged.This paper focuses on effect of corona discharge on surface hydrophobicity of silicone rubber insulator under reduced pressures.The results obtained reveal that under different regions,the corona degradation of composite insulator is accelerated with reducing the pressure.The l... |
