抽油机综合节电箱的研制与应用

Development and Application of Electric-Saving-box in Well Pumping Unit

胜利油田应用星一角转换及电容补偿技术，研制出了跟踪抽油机负荷变化的程序控制星一角自动转换节电箱，现场试验证明，该节电箱较好地解决了目前抽油机电机普遍存在的“大马拉小车”问题，取得了良好的节电效果，并已获得推广应用。

A star-to-angle automatic conVerted electric-saving-box (ESB) with the consulled Program Which lOad change in well pumping unit is followed haS been deVeloped by applying s^angle converted ac capacitance compensated technology in Shengli Oilfield. The test on site has proved that the question of 'a small cart is Pulled by a big horse'in the motor of well pumping unit is well resolVed and good electric-saving effectiveness is achieved. The ESB haS been POpularized and applied.
