重工业粉尘污秽地区常用绝缘子闪络特性的试验研究

Experimental Study on Flashover Characteristic of Insulator in Dust Contamination Region with Heavy Industry

在对辽宁省重度粉尘污秽分布进行调研分析的基础上,对几类主要粉尘污秽进行了成分分析。并在试验站大雾室内对辽宁省常用的双伞型瓷绝缘子和玻璃深棱型绝缘子进行了不同粉尘污秽条件下的污闪试验,对2种绝缘子在重度污秽区域防污闪特性进行了试验研究,给出了对此类地区绝缘子类型选择的参考建议。

In this paper, component analysis is carried out for the main dust contamination based on the research study about the dis- tribution of the dust contamination in Liaoning province. Under the different conditions, pollution flashover test is carried out by using porcelain insulator and glass insulator in fog environment of lab, tlashover characteristic is analyzed. This paper is to provide a refer- ence for type selection of insulator in this region.
