摘　　要：为了研究电爆炸丝长度、根数以及直径对并联电爆炸丝断路开关断流特性的影响,理论分析了并联电爆炸丝断路开关的物理模型,推导了相关设计参数的计算方法,建立了基于时变电阻的仿真模拟模型,并分析了断路时间、断路电流和断流效果等特性的变化规律。结果表明该模型很好地符合实验结果,并能够很精确、便捷、直观地得到电爆炸断路开关断流的一般规律,为设计并联电爆炸丝断路开关的参数选择提供了参考依据。To study the impacts on current breaking characteristics of parallel electro explosive breaker by changing length, diameter and amount, the physical model was analyzed theoretically, and the calculation of the relevant design parameters was derived. The simulation model was established based on time-varying resistance module, the variations of breaking time, current and effect were analyzed. It showed that the simulation fitted the experimental results well, the law of electro explosive breaker could be simulated accurately, easily and intuitively. The study provided a reference for the design of electro explosive breaker.
