摘　　要：运用四边形八结点等参元有限元法对两种不同结构的SF_6断路器灭弧室内的静电场进行了数值计算。通过对100％开距时数值结果的分析,讨论了SF_6断路器灭弧室结构对电场分布的影响,分析了两种结构的优劣并提出了对其中一种结构的改进方案。The electric fields in the arc-extinguishing chambers of the puffer SF6 circuit breakers were calculated using a quardrangle 8-nodded isoparametric Finite Element Method. The influences of the arc chamber structrue on electric field were discussed by analyzing the numerical results of 100% gap distance. Two different arc chamber structrues were compared,one of them was modified to overcome its shortcomings.
