摘　　要：针对混合式直流断路器在短路电流上升沿就开始分断动作的特性,展开短路电流预期峰值以及时间常数对断路器分断过程的影响的分析及仿真试验。通过理论计算以及搭建仿真模型,得出在不同短路电流和时间常数情况下断路器的各项工作指标的变化。according to the characteristics of hybrid DC circuit breaker( starting to act in sections at the rising edge of short-circuit current), the influences of expected peak value of short circuit current and time constant on the breaking process of circuit breaker are analyzed and simulated. Through theoretical calculation and simulation tests, the changes of various working indexes of the circuit breaker under different short circuit current and time constant are obtained.
