摘要
Abstract
The voltage level of:±660 kV Yin-Dong HVDC transmission line reaches a new record in China and even in the world.Since Yin-Dong transmission line was put into operation in 2010,at least five voltage-reduction oper ations have occurred due to abnormal discharges,of which the abnormal discharge on the No.1894 tower was the most typical.In this paper,the abnormal discharge phenomenon of the No.1894 tower in the Yin-dong transmission line is analyzed.Considering its local environment and pollution degree,the causes of the abnormal discharge is investigated.Further,countermeasures against this kind of abnormal discharge are offered for the whole Yin-Dong transmission line.关键词
