摘　　要：研究分析了线路绝缘子表面有雨滴分布时电场分布情况。利用有限元分析软件Ansoft Maxwell构建了线路绝缘子有限元计算模型。通过对线路绝缘子模型仿真分析,得出了伞裙表面未分布雨滴时,伞裙上表面电场分布情况。接着通过仿真分析得出了不同数量雨滴、不同电导率雨滴以及雨滴间相互作用对伞裙表面电场的影响规律。最后归纳总结,提出相应的优化建议,以提高电力系统运行可靠性。This paper mainly studies the distribution of electric field of line insulator when there is raindrop distribution on sheds surface. The finite element model of line insulators is constructed by using finite element analysis software Ansoft Maxwell. By doing simulation analysis on model of line insulators, the electric field distribution on the surface of the umbrella skirt is gotten when there is no raindrop distribution on sheds surface. Then through simulation analysis, the influence of the number and conductivities of raindrops on insulator sheds surface field is obtained, and the influence of interactions between raindrops can be gotten too. In the end, in order to improve reliability of power system, the reasonable optimization suggestions by summing up the above analysis are given.
