Analysis of Heavy Breakdown of 500 kV Circuit Breaker in Converter Station
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.
