南雅河三级电站共装三台高落差高转速水轮发电机组,转速为500转/分,落差为260米,容量为4万千瓦。第一台(2号机)己于83年一季度投产发电;第二台(3号机)也于83年底投产发电。这两台机组都采用了天津电传所制造的它励式可控硅自动励磁调节器,它包括两大部份,即发电机部份(也称主机部份)和交流励磁机部份(也称付机部份)。主机为三相全控整流桥,付机为自励恒压系统,采用三相半控整流桥(见图一至三)。对这两台励磁调节器,进行了近一年 Nanya River Power Station installed a total of three high-altitude high-speed hydro-generating sets, speed of 500 rev / min, a drop of 260 meters, a capacity of 40,000 kilowatts. The first unit (Unit 2) was put into operation in the first quarter of 1983 and the second unit (Unit 3) was put into production by the end of 83. These two units are used in Tianjin Telex-made exciter thyristor excitation regulator, which consists of two parts, namely the generator part (also known as the host part) and the AC exciter part Called pay machine part). Host for the three-phase full-controlled rectifier bridge, pay machines for self-excitation constant voltage system, the use of three-phase half-controlled rectifier bridge (see Figure I to III). The two excitation regulators, carried out for nearly a year
