4000 ~ 9000 m dc control system is an important component of the electric drill.The system includes the diesel generator control unit, dc drive control unit, the driller operation control unit, the electromagnetic brake control unit and five parts such as ac motor control center.The system will be 600 v ac voltage rectifier into 0 ~ 750 v adjustable dc voltage, dc motor stepless speed drive.Through the logic control of dc contactor, switch to different assignment relationship.High production efficiency, stable work, good dynamic performance, load balancing, easy operation, the display is complete, perfect safety protection function.  
3000 ~ 12000 m ac variable frequency control system of the diesel generator control unit and the ac motor control center part and 4000 ~ 9000 m dc control system is basically the same.In the main motor drive and control part adopts the advanced digital variable frequency speed regulation technology and dc chopper technology, make the speed of the motor performance more superior, system control more convenient;And within the scope of speed control can provide high power factor, thus effectively improving the use of the diesel generator power, has obvious energy saving effect.Driven by ac frequency conversion of the 12000 m rig123.net' target='_blank'>drilling rig is currently one of the world's most advanced drill.
