Abstract
Gas insulated switchgear(GIS)circuit breakers are widely used in extra-high or ultra-high voltage power grids due to such advantages as low cost,easy installation,and good seismic performance.Aiming at an accident of internal breakdown and discharge in a 750 kV GIS circuit breaker,from the aspects of on-site inspection,equipment disassembly inspection,electrical,thermal,and mechanical simulation analysis,the root cause of internal discharge in the circuit breaker was analyzed.The corresponding measures were proposed.关键词
