摘　　要：采用8节点等参元法,对SF_6断路器灭弧室内断口间的电场进行了详细的计算。在此基础上分别对喷口,最大开距,主触头结构,主、弧触头间结构的配合等参数的改变对断口间电场的影响,进行了讨论。整个计算软件具有通用性强,使用方便,易于处理复杂边界,前处理简单,后处理形象、直观等优点。The electric field between two contacts within the interrupter of SF6 circuit breaker is made in details using a finite element method.On the basis above,influences of the parameter changes in nozzle,maximum openning distance,main contact structure,coordination between main contact and arcing one,et al on the electric field between contacts are discussed.The software has many advantages such as high generality,convenience for use,accessibility to complex boundaries,simple pre-processing and concrete post-processing and so on.
