摘要
Abstract
An internal discharge fault occurred in an 800 kV gas-insulated switchgear(GIS)circuit breaker at a con-verter station.To identify the discharge path and root cause,comprehensive investigations were carried out,including disassembly inspection,electric field simulation,and insulation operating rod simulation tests.The results indicate that the fault was caused by partial discharge induced by a foreign object inside the enclosure,which led to local electric field distortion.Corresponding mitigation measures are proposed to prevent the recurrence of similar discharge failures,providing a reference for the safe operation and maintenance of GIS equipment.关键词
