污秽表面放电污秽表面放电pollutionsurfacedischarge介质表面沾染污秽时所引起的沿面放电。简称污闪。固体介质表面沾染污秽又同时变潮后，污秽层中所含的可溶性盐类和酸、碱等溶于水膜，形成离子电导，使污秽表面通过较大泄漏电流；沿面闪络电压显著降低，严重时能降低到清洁表面闪络电压的10％以下。雾、露、细雨和溶雪天气时，绝缘子甚至会在工作电压下闪络，严重影响电力系统的安全运行。因此，污闪已成为高压和超高压电工设备选择外绝缘水平的主要依据。防止污闪和提高污闪电压的措施有：①定期清扫和用水冲洗绝缘子和绝缘套管。②改进绝缘子结构使刮风、下雨时能自行清扫。③增大泄漏距离，选取合理的泄漏比矩(每千伏工作线电压需要的泄漏距离)。④给绝缘表面上半导体釉或涂硅油等憎水材料。⑤尽量使高压输电线路避开污秽区，避免在污秽区建高压变电所。600千伏交流电压下陶瓷支架发生火花放电
