一种对工业杂散电流、静电、射频电以及对机械冲击、摩擦高温作用均能起到安全保障的新型雷管——BJ—2型抗电抗冲击工业电雷管最近由北京矿冶研究总院与国营9104厂、北京门头沟电爆技术研究所研制成功。将工频220、380伏交流电源以及各种直流电源接人该雷管引出脚线,均不能使其引爆;将具有上千伏电压的普通电容式起爆器对该雷管脚线放电,也不能使其引爆。对该雷管进行抗冲击试验表明, A new type of detonator for industrial stray current, static electricity, radio frequency electricity, as well as for mechanical impact and frictional high temperature protection - BJ-2 anti-shock industrial electric detonator recently was co-sponsored by Beijing Research Institute of Mining and Metallurgy State-owned factory 9104, Mentougou Beijing blast explosion technology research institute successfully developed. The power frequency of 220,380 volts AC power supply and a variety of DC power supply access to the detonator pin-out, can not make it detonate; will have a kilovolt voltage on the ordinary capacitor initiator detonator pin discharge, nor Make it detonate. Impact test on the detonator shows that,
