广州换流站高压直流设备防污闪措施探讨

Study on Pollution Flashover Prevention for HVDC Equipment at Guangzhou Converter Station

统计分析了广州换流站高压直流设备的污闪放电情况 ,对比分析了目前几种可能的防污闪措施 ,并根据站内高压直流设备的实际运行情况及所处区域的盐密变化情况 ,对广州换流站防污闪措施提出了几点建议。

Flashover phenomena of support insulators and bushings due to contamination at Guangzhou Converter Station are studied. Comparing the advantages and disadvantages of several flashover preventive measures currently available, and according to the practical operation property of equipment at Guangzhou Converter station as well as the pollution index map of this region and the ESDD levels of different type of insulators, several suggestions to prevent pollution flashover at Guangzhou Station are put forward in this paper.
