The contamination of DC silicone rubber insulator has an important influence on its insulation performance and service life, and the adverse effects of swelling effect under the insulation cleaning agent is the key issue to be solved. The volatilization rate of two kinds of electrified cleaning agent, the swelling and hydrophobicity of silicone rubber before and after cleaning by different cleaning agents were studied, and the corresponding mechanism was discussed. The results show that the volatilization rates of No.1 (fast volatilization) and No.2 (slow volatilization) electrified cleaning agents at 25℃ are 1 095.78 g/(h·m2) and 108.01 g/(h·m2), respectively. The swelling index of silicone rubber increases with the increase of time, it reaches saturation after 10 h, and the swelling index of the saturated silicone rubber are 55% and 130%, respectively. The hydrophobicity of silicone rubber is weakened by No.1 cleaning agent, and the contact angle decreases by 14% after soaking for 10 min. The hydrophobicity of silicone rubber is enhanced by No.2 cleaning agent, and the contact angle increases by 6% after soaking for the same time. Therefore, the cleaning agent with excellent volatility can reduce the adverse effect of swelling on the silicone rubber insulators, and can provide basis and reference for the electrified cleaning of silicone rubber insulation equipment.
