51.最大安全电流、最小起爆电流、最低准爆电流如何测定?答:最大安全电流、最小起爆电流、最低准爆电流的数值,由于电雷管的桥丝和引火药的材质、结构不同,变化较大。50微米康铜丝电雷管的最大安全电流为275～450毫安,最低准爆电流为500～700毫安,面镍铬丝电雷管的最大安全电流为130～175毫安,最低准爆电流也较低。出厂的说明书上往往未标明这些数值,因此,掌握它们的测量方
The maximum safe current, the minimum detonation current, the minimum detonation current how to determine? A: The maximum safe current, minimum detonation current, the minimum value of the quasi-detonation current, as a result of electric detonator bridge wire and ignition powder of the material, the structure of different changes Larger. The maximum safety current of the 50 micron constant current electric detonator is 275-450 milliamps and the minimum quasi-explosion current is 500-700 milliamps. The maximum safety current of the nickel-chromium wire electric detonator is 130-175 milliamps and the minimum quasi- Also lower. The factory manual is often not marked on these values, therefore, to master their measuring side
