摘　　要：介绍了一起换流站500kV交流滤波器断路器分闸时重击穿故障,通过解体检查、化学分析、电场仿真等手段进行原因分析,可知断口内固体微粒引起电场畸变,造成重击穿。In this paper,the heavy breakdown fault of a 500 kV AC filter breaker in a converter station is introduced.The fault was analyzed by means of disassembly inspection,chemical analysis and electric field simulation.The solid particles in the fracture caused electric field distortion and caused rebreakdown.

关 键 词：500KV断路器 固体微粒 电场畸变 重击穿
