摘　　要：楚雄换流站开始孤岛调试第四阶段补充实验,当操作到试验项目1的联网转孤岛(16.20_S12)中的第12步:将极Ⅰ高端换流变分接头控制模式由定角度模式改为Udi0模式后极Ⅰ低端阀厅F5避雷器动作,导致的极Ⅰ双阀组闭锁。此次闭锁主要是由于极Ⅰ低端阀厅F5避雷器故障引起的,在以往高压直流输电工程中较为少见,文章将故障分析、处理过程作了总结。The decoupled （island） mode debugging test of Chuxiong Converter Station was began stage 4 - additional test, ＂networking -mode turn to decoupled -mode test＂ Step 12 （16.20_S12） ： pole -I tapped control mode turned fixed -mode to Udi0 mode, pole - I low valve hall F5 arrester malfunction, then pole - I lock. The lock was mainly caused by the pole - 1 low valve hall F5 arrester fault, and it was rare in high -voltage direct current transmission project in the past. So the paper summarized the fault analysis and treating processes.
