摘　　要：本文提出一种双断点限流断路器开断特性计算的数值方法，并把建立电弧数学模型作为重点，利用这种方法不但可以模拟断路器的开断特性，预测它的限流性能，并可以通过计算机的动画技术显示整个开断过程。文中还介绍了这种模拟技术在断路器设计和试验中的应用，并把计算结果与试验结果进行了对比。Computer simulation technique for current limiting circuit breaker with double-breaker is proposed in this paper, in which the emphasis setting up the model of moving arc is placed. It can not only simulate the interrupting characteristics of circuit breaker, but ala can display the moving image of the whole breaking process. The applications of simulating technology in the design and experiment are introduced. Finally, the calculating results are compared with experimental results.
