摘要

为了研究特高压复合绝缘子在长时间电场作用下的电场分布特性

笔者对特高压复合绝缘子进行有限元建模

并计算沿芯棒的电位分布。以完整细剖分模型的计算结果作为基准

将简化模型的结果与其对比来验证简化模型的有效性。通过比较证明了简化模型可以代替完整模型进行复合绝缘子电位分布的分析且能够在很大程度上减小计算规模

对特高压复合绝缘子的建模分析具有重要参考意义。

Abstract

A finite element model is built for ultra high voltage composite insulator to investigate its electric field distribution under long-term electric field effect.The result of complete and fine meshed model is taken as reference to examine the availability of simplified model.The results show that the simplified model could replace the complete model to analyze electric field distribution of an insulator

and diminish calculation cost greatly.It may be very useful for modeling and analyzing the ultra high voltage composite insulator.
