摘　　要：通过实验,研究了充电电压、爆炸箔尺寸、绝缘膜覆盖情况等因素对微型爆炸箔电爆炸特性的影响。结果表明,当回路参数一定时,爆炸箔的爆炸时间主要由充电电压和爆炸箔的横截面积决定,充电电压越高或者爆炸箔的横截面积越小,爆炸时间越短;而爆炸箔长度以及绝缘膜覆盖情况对爆炸箔爆炸时间的影响较小。此外,实验还给出了微型铜箔横截面积为100~600μm^2时的电压起爆阈值,能够为以微型爆炸箔作为导通元件的平面介质开关的优化设计提供参考。The influence of the input voltage,size of the exploding foil,and the covering material on the exploding characteristics of the micro-size exploding foil were investigated by our experiment.The results show that the exploding time span is mainly determined by the input voltage and the cross section of the exploding foil and,in addition,neither the length nor the covering material of the exploding foil have any significant effect on its exploding characteristics.The exploding time span tends to get shorter with the increasing of the input voltage and the decreasing of the cross section area.Besides,the threshold curves of the electric-explosion of the micro-copper foil with certain circuit parameters are obtained from the experiment,which can provide valuable information on the optimization of the design of the micro-exploding foil.
