摘要

不同污染源影响绝缘子积污量

对污秽的理化性质也有较大影响。文中选取江苏盐城各县市不同污染源附近的6个绝缘子悬挂点

通过取样分析悬挂点绝缘子的等值附盐密度（ESDD）和等值附灰密度（NSDD）及其污秽可溶物、不溶物中阴阳离子体积分数和上、下表面污秽颗粒粒径的变化

研究分析了不同污染源附近绝缘子自然积污规律。结果表明:连续积污两年后

各污染源附近绝缘子下表面的盐密和灰密高于上表面;水泥厂、热电厂、镍厂和工业园区附近绝缘子的污秽度要大于农田公路区和化肥厂

平均灰盐比以水泥厂附近绝缘子3.28为最高

化工园区1.75为最低;不同污染源绝缘子表面污秽物的理化性质存在很大差异。建议外绝缘设计及线路运行维护中充分考虑上述积污特点。

Abstract

In order to study the contamination accumulation rules of insulators around different pollutant sources

the author selects six test sites near different pollutant sources in Yancheng city

Jiangsu province

the variation of ESDD and NSDD

and the

icon content and particle size distribution are analyzed.The results are as follows:after a2-year pollution period

the upper-surface ESDD and NSDD of insulators around different pollutant sources are higher than those on under-surface;The filth of insulators at cement plant

coal-fired plant

nickel plant and industrial park is higher than that at fertilizer plant and highway-farmland area. The average ratio of ESDD to NSDD of cement plant insulators is up to 3.28

which of chemical industrial park is lowest to 1.75;The physical and chemical properties of dust on insulators have big difference between diverse pollutant sources. It is recommended that these features of pollution deposit should be adequately considered in outdoor insulation designing and operation maintenance.
