摘要/Abstract

摘要： 为提高爆炸箔起爆器的能量利用率，本文对其主要影响因素之一爆炸箔桥箔进行了研究，测定了3种不同形状爆炸箔桥箔的爆发电流，并对起爆炸药HNS-IV进行了飞片感度试验。试验结果表明圆形桥箔的爆发电流密度最大，起爆HNS-IV的50%起爆电压最低，爆炸箔起爆器(EFI)选用圆形爆炸箔桥箔可以进一步提高能量利用率，降低发火能量。

Abstract: In order to improve availability of the energy in exploding foil initiator(EFI), the exploding foil bridge shape, which is main influence factor on it, was studied. The burst currents of three kinds of bridge foils with different shapes were measured, and the sensitivity of initiation charge made from hexanitrostilbene-IV (HNS-IV) was tested by slappers. The tested results show that, for the rouna shape bridge foil, the burst current density is maximum, the initiating voltage at 50 % firing probabili?ty of HNS-IV is minimum, the availability of energy is improved further and the iirmg energy is re?duced .

Key words: electrical engineering , exploding foil , bridge foil , burst current density , flyer velocity
