摘　　要：本文提出了计算稳态燃弧时ＳＦ６灭弧室内的热气流流场的新的有限元算法，并用此方法计算了灭弧室内电弧与气流的耦合流场，通过主要参数变化情况的分析，说明了电弧阻塞效应对电弧与气流相互作用产生的影响。A new finite element method has been provided for calculating hot gas flow field during current arcing period in arc chamber of SF6 Breaker. Interacting between arc and flow are discussed numerically in this paper. By studying changes of some main parametrs, we tried to describe influences between arc and flow in effect of nozzle clogging by arc.
