对于200米以上的水头来讲,萨彦舒申斯克水电站的水轮发电机组,无论在量或是尺寸方面都是世界上最大的。由于进行了大量的综合性科研和结构试验工作,该电站已取得了水头达230米的水轮机转轮的新系列,提高了过流量,有较好的气蚀性能以及很高的效率。混流式水轮机:型号PO230/833—677,转轮直径6.77米,由苏联列宁格勒金属工厂制造。设计水头194米,出力65万千瓦,流量358立米/秒。在水头为212～220米范围内,水轮机限制出力为73.5万千瓦。在水库蓄水期,水轮机可以
For a head of more than 200 meters, the turbine generator set at the Sakyan Shushenskaya hydropower station is the largest in terms of quantity or size. Thanks to a large amount of comprehensive research and structural tests carried out, the plant has achieved a new series of turbine runners up to 230 meters in height, improved over-flow, better cavitation performance and high efficiency. Francis turbine: Model PO230 / 833-677, rotor diameter of 6.77 meters, manufactured by the Soviet Union Leningrad metal factory. 194 meters head design, output 650,000 kilowatts, flow 358 cubic meters / second. In the head of 212 ~ 220 meters range, the hydraulic turbine output limit of 735,000 kilowatts. In the reservoir storage period, the turbine can
