摘要
阐述220kV双母双分段接线方式中的某一条母线停役,更换压变同时修理母线刀闸,发现电压切换回路异常,造成停役母线后台显示电压仍然存在,探讨电压切换回路异常的风险隐患。
This paper expounds the shutdown of a certain busbar in the 220kV double busbar and double segmented connection method,where the voltage transformer is replaced and the busbar knife switch is repaired.It is found that the voltage switching circuit is abnormal,causing the voltage displayed in the background of the shutdown busbar to still exist.It explores the risks and hidden dangers of abnormal voltage switching circuit.
