对调压式抽油机节能控制器的新认识

调压式抽油机节能控制器是采用双向反并联可控硅进行控制的三相交流调压技术，通过检测电机电压与电流之间的相位差变化作为控制信号，控制晶闸管的导通角，从而改变电机的工作电压，使电机在空载或轻载时的工作电压低于额定电压运行，从而达到节能的目的。该节能器因其节能效果好，保护功能多，对电网污染小，受到现场人员的青睐。

The New Recognize for Voltage-adjusting Pump Unit Energy-saving Controller

Phase angle between voltage and current change bychange of load in motor is used on pumping unit. Thephase angle tells the level of motor power factor. Voltage-adjusting Pump Unit Energy- saving Controller adoptstriphase alternating current voltage -adjusting technologycontrolled by bilateral anti-parallel silicon control tocontrol angle of flow of silicon control with thecontrolling sigh of the change of phase angle betweenvoltage and current to change working voltage of motor.It makes working voltage of motor smaller than ratedvoltage to have energy- saving effect when there is noload or light. The motors are in good graces of oil fieldby good energy-saving effect and multi-protect and smaller harmonic wave pollute.
