摘要
以某地区11个变电站35 kV、110 kV和500 kV支柱绝缘子为研究对象,对其表面积污进行了现场测试,根据测试结果定义了6种不均匀系数k,系统分析其高压组、接地端与中部、上表面与下表面、灰密和盐密的不均匀积污特性,得到该地区支柱绝缘子的污秽度和不均匀度数值的频数分布。
In this paper,the surface contamination of 35 kV,110 kV and 500 kV post insulators in 11 substations in an area is tested in the field.Six kinds of non-uniform coefficients K are defined according to the test results.The non-uniform contamination characteristics of high-voltage terminal,grounding terminal and middle,upper and lower surfaces,NSDD and ESDD are analyzed.The frequency distribution of contamination and non-uniformity values of post insulators in the area is obtained.
