摘要

绝缘子表面积污状况与污区划分及外绝缘的选择密切相关

是外绝缘的基础性工作之一。为此

文中选取10支深圳地区岭深线路交流500 k V复合绝缘子并对其积污特性展开研究。对测试结果进行方差分析发现

岭深线不同地形条件绝缘子整体积污状况接近

而同一支绝缘子不同部位表面积污状况存在差异

表现为:靠近绝缘子串两端的伞裙单元盐密值较大;绝缘子伞裙上表面积污重于下表面。上述测试结果表明复合绝缘子表面积污存在不均匀性

在进行复合绝缘子人工污秽试验时

应充分考虑复合绝缘子的积污特点。

Abstract

Pollution severity on insulator surface is related to the pollution areas classified and the determination of the insulation level

which is one of the basic problems for external insulation.This paper selects 10 composite insulators on 500 k V Ling-Shen AC transmission line in Shenzhen and investigates the natural contamination characteristics of insulators.The results of variance analysis show that the amount of pollution in different areas are close

however the pollution distribution along the string is uneven.The ESDD is higher at both the end of insulator and the pollution of the upper surface is more serious than lower surface on the insulator itself.This paper presents the non-uniform characteristics of contamination distribution

which should be taken into consideration in artificial pollution test.
