In order to study the natural contamination chemical composition of line insulator in Guangzhou area, natural contamination measurement sites were established, natural contamination was collected, and its chemical composition was measured. According to analyzing the content of natural contamination chemical composition, the heterogeneity of chemical composition between upper surface and under surface,...
Rainfall causes decrease of contamination of insulators, which is closely related with the electrical performance of outdoor insulators of high voltage transmission lines, because it reduces the risk of pollution flashover. To study the washing effect of rainfall on contamination of porcelain and glass insulators, an artificial rainfall experiment platform has been designed, fabricated and tested...
The continued dry weather usually caused the increasing risk of flashover of the transmission line insulators. But there is still a lack of effective means to deal with this specific risk, because the rule of pollutant accumulation is still not fairly known. This paper pointed that the global climate changes in the characteristics of abnormal in recent years. And based on that, the limitations of...
This paper mostly study a 220 KV suspension insulator string in the highway district and the highway-farmland district of South China, through periodic sampling of insulator surface dirt, analyzing contamination degree and contamination components on insulators of different topography, taking further analysis of impacts of different contamination components on ESDD, NSDD, and finally draw the conclusion...
