摘　　要：提出了一种分析发生在压气式断路器开断过程中灭弧室中气体流动的计算模型。并用一种新的差分法即改进型ＦＬＩＣ法编制程序计算了５５０ｋＶ 双断口压气式ＳＦ６ 断路器在空载及负载工况下灭弧室内的气体流动， 通过对比分析，A model to analyze the gas flow in the arc quenching chamber of the puff type SF 6 gas circuit breaker during short current interruption has been presented,and a calculating program has been built employing the modified fluid in cell method(FLIC).The gas flow field in the chamber of a puff type double breaker 550kV SF 6 gas circuit breaker during both loading and non loading interruption has been calculated using above program.By contrasting the calculating results,the effects of the arc on gas flow in the chamber have been analyzed.
