12千瓦以下的小水电,称微型水电。微型水电机组有混流式、轴流式和斜击式等几种型式。其中,斜击式的微型水电机组,制造容易,过流量较小的水源也可建站发电,具体结构见图。凡是电网达不到的农村、无电的山区、边疆、海岛和铁路沿线小站等,只要具有一定的水源条件,均可建站。斜击式微型水轮机性能见表1,配套情况见表2,引水压力管径D见表3。 Small hydropower below 12 kilowatts, called micro-hydropower. Micro-hydropower units are mixed flow, axial and oblique type, and several other types. Among them, oblique-type micro-hydroelectric generating units, easy to manufacture, over-flow of water can also be built smaller station, the specific structure shown in the figure. Any rural areas not reached by the power grid, mountainous areas without electricity, small stations along the border areas, islands and railway lines, and so on can all be stationed as long as they have certain water source conditions. Oblique-type mini turbine performance shown in Table 1, supporting the situation in Table 2, diversion pressure diameter D see Table 3.
