摘要

基于复合绝缘子的污闪理论

通过两种简化的硅橡胶平板模型

应用电场有限元计算软件ElecNet分别模拟了复合绝缘子护套表面和伞裙表面水滴的电场特性

着重研究比较了水滴的体积、接触角、形状等参数对水滴表面电场的影响

分析了两种模型中影响水滴表面电场强度的主要因素

并计算了复合绝缘子表面附着水滴时的电场

得出复合绝缘子伞裙上下表面以及护套表面附着的分离水滴使电场大大增强的结论。

Abstract

The electric field characteristics of water droplets on surfaces of sheath and shed of polymer insulators are studied by means of two simplified flat silicone rubber sheet models.This study adopts both the pollution flashover mechanism of polymer insulator and the electric field computation software ElecNet.Effects of volume

contact angle

shape

and other parameters of water droplet on electric field are compared

and the main factors are obtained.The electric field distributions on polymer insulators with discrete water are also analyzed.
