摘要

经过对两次污闪和雾闪现象的直观对比

分析了长时间浓雾天气条件下绝缘子的飞弧桥接现象

指出防污型绝缘子因其电压分布的不均匀和伞裙间的距离过小以及合成绝缘子在长时间浓雾天气条件下憎水性的丧失

是造成雾闪和湿闪的主要原因

并提出了具体建议。

Abstract

Based on the two incidents of the pollution flashover and the fog flashover

the "interlinking phenomenon" of insulator flashover in the envioronment of long term dense fog is analysed. Conclusion is obtained that the non uniform voltage distribution

the shorter shed space of insulator and the loss of hydrophobicity of the insulator are the main reasons leading to fog flashover and humidity flashover.
