In this paper,we combine the oil field production circumstances and investigate the variable voltage energy-saving control system that the variable voltage trace the changes of the load.Through measuring the change of phase angle between voltage and current to become the controlling signal.We control the flow angle of the crystal thyratron,hence this changes working voltage of the motor.It makes the variable voltage to change according to the changes of the load,to bring about the ideal matching with the load,to attain the objective of saving on electric energy with the low wastage and the high efficiency.
