基于Ansoft的冰凌分布对绝缘子周边电场的影响研究

主要研究分析了线路绝缘子表面有冰凌分布时周边电场分布情况。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,得出了绝缘子表面没有冰凌存在时周边电场的分布情况。接着通过仿真分析得出了冰凌的分布量、长度以及直径对绝缘子周边电场的影响规律。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。

The Influence Of Distribution Of Ice On The Surrounding Electric Field Of Insulator Based On Ansoft

This paper mainly studies theelectric field distribution on the surroundingof insulatorwhen there is ice on sheds surface.Thefinite element analysis software Ansoft Maxwell is used to construct the finite element model of line insulators.We get electric field distribution on the surrounding of insulator when there is no ice distribution through doing simulation analysis on model of line insulators.And then,we get the influence of the number, length and diame-ter of ice on the surrounding electric field of insulator through simulation analysis.Finally, in order to improve relia-bility of power system, we make reasonable optimization suggestions by summing up the above analysis.
