研究了特定点火装置在充电电压为2000V和2500V条件下不同截面积桥箔的爆发电流、爆炸时间,预估了飞片的最大击靶速度。通过研究得到了与特定点火装置相匹配的桥箔截面积和该截面下爆炸箔起爆HNS-Ⅳ时的50%发火电压。研究结果可对冲击片雷管发火能量的优化设计提供一定的技术支持。
The ignition current and explosion time of bridge foil with different cross sections under the condition of 2000V and 2500V are studied in this paper. The maximum target flying speed of flyer is estimated. Through the research, the cross-sectional area of the bridge foil matching with the specific ignition device and the 50% firing voltage of the HNS-IV detonated by the explosion foil under the cross section were obtained. The research results can provide some technical support for the optimization design of the ignition energy of the impulse detonator.
