五、双绕组电抗分流励磁装置改进接线存在的问题1.改进接线的原因双绕组电抗分流式励磁装置原理接线图如图6(a)所示。这种水轮发电机定子绕组分为主绕组和附加绕组,按图示接法,通过带有可调气隙电抗器接入三相桥式硅整流器整流后,作为发电机的励磁电源。因此,发 Five, double-winding reactance shunt excitation device to improve the existing problems 1. Improve the wiring of the reason Double winding reactive shunt excitation principle wiring diagram shown in Figure 6 (a) below. The stator winding of the hydroelectric generator is divided into main winding and additional winding. According to the diagram connection method, the three-phase bridge silicon rectifier with adjustable air-gap reactor is rectified and used as the excitation power of the generator. So hair
