摘要
660kV银东直流线路电压等级是我国乃至世界上新的直流输电电压等级,在我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五次因线路异常放电导致的降压运行,其中以#1894耐张塔的异常放电问题最为典型。本文基于银东直流#1894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塔乃至整个银东直流线路异常放电现象的对策。
The voltage level of±660kV Yin-dong HVDC transmission line is a new DC transmission voltage level in China and even in the world.After Yin-dong transmission line was put into operation since 2010,abnormal discharges occurred at least five times which accordingly resulting in the reduced voltage operation of the line.The abnormal discharge phenomenon of#1894 transmission tower was the most typical one.In this paper,the abnormal discharge phenomena of#1894 tower in the Yin-dong transmission line was studied.Effect of the local environment and pollution degree on discharge was analyzed.On this basis,the countermeasures of the abnormal discharge were proposed for the#1894 tower,even for the whole Yin-dong transmission line.
