自然污秽直流线路支柱绝缘子的实验室试验

open access: yesDianci bileiqi, 1989
曾在美国西勒弥直流换流站自然污秽条件下运行的支柱绝缘子在日本高压试验室作了试验.在雾室中试验了2只400kV支柱绝缘子(高4600mm,由4节高1150mm、平均直径225mm的绝缘子组成,总爬电距离12800mm)和1只500kV支柱绝缘子(高4600mm,由2节高2300mm绝缘子组成,平均直径313mm,总爬电距离1600mm).太平洋直流输电1970年以±400kV投入运行,1985年电压升高到±500kV.运行期间发现了直流绝缘的污秽闪络.在电源±750kV输出电容1 ...
