| Abstract: | A pumped storage power station 500 kV GIS disconnection and tested the risk of Switching overvoltage,in this paper,the causes of the disconnection switching overvoltage was analyzed,adopting measures such as changing disconnection and contact breaker structure to reduce the possibility of switching overvoltage,introduces the disconnection the transformation process and matters needing attention,after the completion of the disconnection and the running in good condition,can provide reference for other similar equipment operations. |
