一种能防误起爆的井用起爆装置
摘要：
本实用新型涉及一种能防误起爆的井用起爆装置，220V交流电分两路接入直流电源U1，直流电源U1分三路：一路依次接指针电压表U2、起爆继电器U3、双向指针电流表U4、极性切换继电器U5、断路开关U6、短路开关U7、连接器U8；一路依次接钥匙开关U9、电缆极性选择开关U10、正电起爆开关U11、负电起爆开关U12；一路接入调压旋钮U13。起爆继电器U3分接正、负电起爆开关U11、U12。处理器U14分接电缆极性选择开关U10、正、负电起爆开关U11、U12。本实用新型每个电缆极性选择开关对应井下雷管极性状态指示，正负电起爆按钮独立设置，起爆安全性高；能解决误操作、误动作、线缆残留高电压误起爆射孔。
摘要（英）：

The utility model relates to a can prevent detonating initiating device for well of mistake, 220V alternating current divide two the way to insert DC power supply U1, and DC power supply U1 divides the three routes: meet pointer voltmeter U2, detonating relay U3, two -way pointer ampere meter U4, polarity transfer relay U5, cutoff switch U6, short circuiting switch U7, connector U8 all the way in proper order, meet key switch U9, cable polarity select switch U10, positive electric initiating switch U11, the detonating switch U12 of negative electricity all the way in proper order, insert voltage regulation knob U13 all the way. Detonating relay U3 shunting just, the detonating switch U11 of negative electricity, U12. Treater U14 tapping cable polarity select switch U10, just, the detonating switch U11 of negative electricity, U12. The utility model discloses every cable polarity select switch corresponds detonator polarity condition indication in the pit, positive and negative electric initiating button independent setting, and detonating security is high, maloperation, malfunction, cable can be solved and the detonating perforation of high voltage mistake is remained.
