鸭河口水库第二水电站属坝后式电站,因原设备设计制造缺陷较多,使发电机定子铁芯松动变形严重,定转子温升过高,线圈绝缘老化严重。1996年对2号机更新转子励磁绕组,在不更换水轮机和其它设备的情况下,单机可增容200kW~400kW,共投资73.5万元。两年内可收回投资,经济效益显著。图1幅。表2个。
The second hydropower station of Duhekoukou Reservoir is a post-dam hydropower plant. Due to the large number of design and manufacturing defects of the original equipment, the stator iron core of the generator is loosely deformed and deformed. The temperature rise of the stator is too high, and the aging of the coil insulation is serious. In 1996, the No. 2 machine renewed the rotor excitation winding. Without changing the turbine and other equipment, the capacity of single machine can be increased 200kW ~ 400kW, a total investment of 735,000 yuan. Two years to recover the investment, significant economic benefits. Figure 1 picture. Table 2.
