摘　　要：提出了计算稳态燃弧时SF6灭弧室内的热气流流场情况的新的有限元算法,分析了电弧与气流场的耦合,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. Interaction between arc and flow is discussed in this paper. By studying changes of some main parameters, we tried to describe influences between arc and flow in effect of nozzle cloggng by arc.
