摘要
分析了舟山直流输电工程宁波换流站换流阀避雷器损坏的事故原因 ,对于 1 3年运行中首次发现的逆变器某个阀不导通产生严重过电压的问题有了较深刻的认识 。
The failure cause of MOA at converter valves at Ningbo converter station of Zhoushan DC transmission project was analysed A deeper knowledge about severe overvoltage stress caused by first discovered refusal of a converter valve to breakdown A countermeasure form such a incident is presented
