输电线路积污的化学成分分析

线路绝缘子表面积污的化学成分关系到污闪的发生。而线行在不同地带,积污条件和积污的化学成分不同,污闪发生概率有较大差异。这里对广州供电局高压架空输电线路7个监测点的绝缘子积污的化学成分分析,作为判定不同地带的等值盐密一个补充依据。

Chemical composition Analysis of Transmission Line Pollution

The chemical composition of pollution depositing on the surface of the power transmission line insulators have a direct influence on the occurrence of pollution flashover.Different terrains along the corridor of power lines will have different pollution depositing conditions,result different chemical compositions of deposited pollution and hence result different flashover probabilities.Here quantitative chemical analysis has been made with pollution examples gathered from 7 pollution monitoring points of HV over-head power lines of Guangzhou Power Supply Bureau.The data obtained are taken as basic back ground for determining the equivalent salt densities of relevant areas.
