【摘要】 为研究不同桥丝式火工品静电安全性的差异,采用静电放电模拟装置分别对两种典型的热桥丝式和爆炸桥丝式火工品进行了静电安全性试验,测试获得了1000p F,1?静电放电条件下两种火工品50%发火电压及其桥丝50%熔断的电压值,并通过理论计算对试验中桥丝的响应状态进行了分析。结果表明,从静电放电导致的桥丝温升和其熔点温度值对比来分析桥丝的响应状态是可行的;EBW-1爆炸桥丝式火工品桥丝熔断不一定会引起其发火,而HBW-1热桥丝式火工品桥丝未熔断也能导致其发火,两种火工品不同的起爆机理是造成上述静电安全性差异的主要原因。更多还原

【Abstract】 The electrostatic safety of hot bridge wire(HBW) and exploding bridge wire(EBW) detonators 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 1000 p F,1Ω, and the the response of bridge wire to ESD was analysed 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 of electrostatic safety of two types of detonators is mainly caused by the different initiation mechanisms.更多还原
