摘　　要：采用高压静电放电模拟试验系统,在250kV,1000pF,1Ω的条件下,对某爆炸桥丝火工品脚-脚和脚-壳两种静电放电方式下的响应特性进行了试验研究。结果表明,脚-脚方式静电放电条件下,火工品桥丝随加载电压的升高出现熔融、断裂以及爆炸等反应,其50%概率断裂电压为56.33kV,但桥丝爆炸并未引起火工品发火。在脚-壳方式静电放电条件下,火工品典型的响应特性为电极塞和壳体发生分离。分析认为,爆炸桥丝火工品高压静电放电响应特性与静电放电的能量分布、火工品的结构组成及其起爆机理等有关。The response of exploding bridgewire detonators with two different（pin-pin and pin-shell）discharge types to high voltage electrostatic discharge（ESD）was studied using a high voltage ESD test system at the circuit parameters of 250 kV,1000 pF,1Ω.Results show that melting,fracture or explosion（without ignition）of bridgewire detonators can be observed when ESD was applied to pin-pin discharge.The 50% broken voltage of bridge wire is 56.33 kV.The typical response of detonators to ESD is electrode plug breaking away from shell when ESD applied to pin-shell.The response characteristic of detonator to high voltage ESD is found to be ralated with the ESD energy distribution,the structure and the ignition mechanism of detonator.
