摘要
基于开发的三维有限元仿真软件计算了 SF6 罐式高压断路器灭弧室内的三维电场 ,得到灭弧室内的电场强度分布 ,发现喷口对灭弧室中电场分布的影响较大 ,它的存在使触头附近电场及其变化增大 。
Software technology is studied and a finite element software is developed in this paper. The three dimension electric field of tank type circuit breaker is computed by this software. The distribution of electric field intensity is obtained and the effects of nozzle are analyzed emphatically.
