Features :

The electricity and control system by ZPEC can be used for 3000 to 9000 meters rigs VFD and SCR systems for client option.

The SCR drive system can be used for controlling SCR element rectifying the constant voltage and frequency AC power into continuous adjustable SCR power which makes it possible to control the drawworks of drilling rig mud pump rotary table or the speed and torque of top drive and it can realize stepless speed regulation and meets the drive requirement.

Full numerical VFD is adopted to realize 4-frame control and non-polar smooth regulation. Combined with the advanced VFD and conventional pneumatic control and hydraulic disc braking they are conformed to PLC so as to make the control performance at the state-of-the-art level.
