一种单速三功率档节能型电机在抽油机中的应用

Application of A Single-Speed Three-Power Energy-Saving Motor in Pumping Unit

油田抽油机专用电动机,在同一台电机中根据油量负载大小不同来实现选用三种不同的功率档进行控制使用。介绍采用同一相绕组中根据需要的三档功率进行线圈匝数比的抽头,构成新的大小不等的Y-△接法的计算方法,在三种功率选择控制使用的情况下,确保额定转速、效率、功率因数、力能指标相近的原则,达到方便现场操作、节约能源的目的。

Special motor of oil pumping unit, according to the same motor fuel load to achieve using three different powers. Using the same phase winding of the third gear power needed to tap the coil turns ratio was introduced, Constitute a new Y-A sizes connected in the calculation. In the case of three power options, ensure that the rated speed, efficiency, power factor, power index of similar principles, to facilitate on-site operation, energy savings.
