摘要

±660 kV银东直流线路电压等级是中国乃至世界上新的直流输电电压等级

在中国乃至世界范围内尚属建设与运行先例。自2010年投运以来银东直流线路累计发生5次因线路异常放电导致的降压运行

其中以1894号耐张塔的异常放电问题最为典型。文中基于银东直流1894号塔现场异常放电现象

对其进行分析研究。同时结合该塔的污秽度研究

综合考虑其地理位置及环境因素

对该塔的异常放电原因进行分析研究。在此基础上

提出应对1894号塔乃至整个银东直流线路异常放电现象的对策。

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.
