摘要

不同的地形地貌不仅影响绝缘子的自然积污量

而且对其污秽成分有很大的影响。笔者主要针对处于华南地区公路区和公路农田区的一段220 kV线路的悬式绝缘子

对绝缘子表面污秽进行周期性采样

分析不同地形地貌的污秽度及绝缘子污秽成分

进一步分析不同污秽成分对盐密（ESDD）、灰密（NSDD）的影响

得出公路区和公路农田区的绝缘子积污对输电线路外绝缘影响的结论。结论可作为绝缘子运行维护、选型、设计的参考依据。

Abstract

For a 220 kV transmission line at highway area and highway-farmland area in South China

the contaminations on the hanging type insulators are sampled periodically to understand contamination degrees and compositions at different topographies

and analyze the effects of different contamination compositions on ESDD and NSDD.Conclusion is drawn to offer a reference for operation maintenance

type selection and design of this type of insulators.
