1 工程概况南湾水电站工程建于1958年,坝后式电站,原装有4台1360kW水轮发电机组,采用PO-K-3-BM-126型水轮机配TS-252/30-20型发电机,设计水头20m。1984年更新改造了控制保护装置,采用集控式晶体管逻辑控制和晶体管保护。1992年对3、4号机组进行了更新增容改造,采取H1260-LJ-126型水轮机配SF1600-20/2600型发电机,单机增容至1600kW,设计水头21.2m。发电机开关为SN10少油断路器,高压设备布置于主厂房发电机层,两台主变分别为SJ-3200/38.5和S7-
1 Project Overview Nanwan Hydropower Station project was built in 1958, dam-type power plant, the original 4 sets of 1360kW hydro-generator sets, the use of PO-K-3-BM-126 turbine with TS-252 / 30-20 generator , Design head 20m. Updated in 1984, the control and protection devices, the use of centralized control transistor logic control and transistor protection. In 1992, Unit 3 and Unit 4 were retrofitted and rebuilt. The turbine of Model H1260-LJ-126 was equipped with SF1600-20 / 2600 generator. The unit capacity was increased to 1600 kW and the head was designed to be 21.2 m. Generator switch SN10 less oil circuit breakers, high-voltage equipment arranged in the main plant generator layer, two main transformer respectively SJ-3200 / 38.5 and S7-
