摘要

复合绝缘子外形及结构特点使得其电位分布不均匀

两端金具附近电场强度较大

容易发生电晕放电

对绝缘子安全运行带来危害。为改善绝缘子电场及电位分布

基于有限元电场计算

以220 k V复合绝缘子为研究对象

考虑在高压端和低压端金具串联玻璃或瓷绝缘子的几种情况

分别建立三维仿真计算模型。研究结果表明:串联绝缘子后

复合绝缘子承担电压降低

整体电位及电场分布得到改善

并消除了金具附近的场强畸变。以控制220 k V复合绝缘子表面最大场强在4.5 k V/cm以下为目标

采取在低压端串联3片绝缘子或高压端串联2片的方式

均可以满足要求。

Abstract

The shape and structure of composite insulator makes its potential non-uniform. The value of electric field in the area which locates near both ends of fittings of the insulator is very high; as a result

corona discharge occurs very easily

doing harm to its safe operation. In order to improve the electric and potential distribution of insulator

based on the finite element calculation

the present paper takes 220 k V composite insulator as the research object

in series glass or porcelain insulator with the both ends of fittings of the insulator respectively

establishing three-dimensional simulation model. The results show that after connecting insulator the voltage of the composite insulator is reduced and its overall potential and electric distribution is improved

besides

field distortion near the fittings is eliminated. Aiming to control the maximum field on the surface of 220 k V composite insulator below 4.5 k V/cm

3 pieces of insulators can be in series with the low-voltage fitting or 2 pieces of insulators with the high-voltage fitting.
