摘　　要：为研究不同桥丝火工品静电放电响应的差异,采用高压静电放电模拟装置对两种典型的热桥丝和爆炸桥丝火工品进行了脚-脚电流注入式静电放电,测试获得了两种火工品50%发火电压及其桥丝50%熔断电压值,并对火工品的响应状态进行了理论计算和分析。结果表明:火工品桥丝的响应状态可根据静电放电引起的桥丝温度与其桥丝材料熔点温度值的对比来判定;爆炸桥丝和热桥丝火工品不同的起爆机理是造成其静电响应特性差异的主要原因。The response of hot bridge wire（HBW） and exploding bridge wire（EBW） detonators to high voltage electrostatic discharge（ESD） was studied using a ESD equipment. The 50% melt fracture voltage of bridge wire and the 50% ignition voltage of detonators were got with the experimental circuit parameters of 1 000pF, 1~, and the the response of bridge wire to ESD was analyzed by theoretical calculation. The results show that, the response of bridge wire can be explained by comparing the temperature caused by ESD with the melt temperature of bridge wire. The difference response characteristic of two types of detonators is mainly caused by the different initiation mechanisms.
