Abstract

Abstract: The related situations of two times abnormal tripping incidents of 220kV high voltage switch in Changzhou Hydropower Station were introduced. The reasons of abnormal tripping were analyzed. The technical measures and management measures for effectively preventing the abnormal tripping of 220kV high voltage switch were put forward, which ensures that the high voltage switch operates safely and reliably after it was put into operation.

Key words: hydropower station, high voltage switch, trip, analysis
