Failure Analysis And Simulation Of800kV Can-type Breaker’s Insulated Rod

A study about several800KV can-type breaker that work in NingXia EHV have done in this paper. Analysis about insulated rod electric field intensity distribution of different type and a800kV can-type breaker simulation is taken. Electrical properties and structural features research is taken to analyze fault situation through actual operating conditions recent years. Calculation about variation of insulated rod electric field intensity distribution considerate the influence. The influence when insulated rod is broken is analyzed through simulation. Grasp the stress conditions in fact through a strain signal test in the process that when insulated tension pole being operated, and provide datasheet for insulated tension pole failure experiment through the stress simulation. And the analysis and calculation work as a theoretical basis to optimize design of800kV can-type breaker to ensure safe operation. And this could be a reference for all the application of800kV can-type breaker.
