摘　　要：以双断口断路器模型为研究对象，分别从气流场数值分析和试验角度探讨了不同电弧运动通道结构的影响。提出了一种有利于抑制断路器开断过程电弧重击穿现象的收缩型电弧通道。The effect of running channel on the restriking phenomena of interrupting process incurrent limiting circuit breaker with double-break is investigated.Numerical analysis of fluiddynamics for different configurations of arc running channel shows that in contrast to parallelchannel,the restriking phenomena can be weakened when arc running in shrinkage channeldue to the back flow of hot gas to be restrained.An optoelectronic measuring system is ap-plied to monitor the restriking phenomena in experiment.The testing results also demon-strated that shrinkage channel is of benefit to improve the current limiting performance oflow-voltage circuit breaker。
