合成绝缘子表面电压和场强计算
摘要
利用表面电荷法对绝缘子表面的电压分布和场强进行了计算
研究了影响电压分布的某些因素
如均压环、伞裙对电压分布的影响。计算表明
合成绝缘子的电压分布特性与瓷质绝缘子有很大不同
其电压分布非常不均匀
高压端承受了更高的电压。伞裙和均压环均能改善电压、场强分布
但合成绝缘子均压环对电压分布均匀性的改善不如瓷质悬式绝缘子。
Abstract
In this paper
the Surface Charge Simulation Method(SSM)is used to compute the potential distribution and electric field along the surface of composite insulator.Some factors to influence on the potential distribution are studied.The results show that the electric field along com-posite insulator surface is non-uniform severely with the HV terminal bearing more potential stress
quite different from that of porcelain insulator string.The grading ring and skirts can improve the uniformity
but not as good as be used in porcelain insulator string.
