摘要

笔者选取中国珠江三角洲地区220 kV输电线路上的4个试验点

结合珠三角地区的年降水分布与城市热岛效应等因素

通过分析试验点上绝缘子的盐密（ESDD）和灰密（NSDD）变化来研究珠三角地区不同地形下绝缘子表面积污积累规律。研究表明:绝缘子的ESDD受降雨影响较大而NSDD较小;影响绝缘子积污的主要因素是降雨量和污染源;绝缘子的最大污秽度出现在雨季第1场降雨之前;不同地形下绝缘子表面积污积累规律不同;热岛效应在污秽积累过程中起了重要作用。

Abstract

This article selects four test sites in the Pearl River Delta in China on the electric transmission line of 220 kV

in order to study the rules of insulator contamination accumulation of various landforms in the Pearl River Delta

the change of ESDD and NSDD are analyzed combining the distribution of precipitation and the urban heat island effect.According to the study: ESDD of the insulator is much easier to be affected by the rainfall than NSDD;both the rainfall and pollution source are the key factors of the insulator contamination accumulation;the highest insulator contamination will be appeared before the first rainfall of the rainy season;there are many differences of the insulator contamination accumulation rules in various landforms

the heat island effect make a great influence.
