青桐电站因上游水库扩容,来水量增加,决定对1号机组实施更新改造,在不改变原来引水管道的前提下将机组出力由1510kW提高到2200kW。应用现代设计技术,设计电站专用水轮机,适当提高新转轮的过水能力,采用多种新技术,新材料和新工艺使机组效率比原机组高,耗水量却比原机组少。表1个。 Qingtong power station due to the expansion of upstream reservoirs, water increased, the decision to Unit 1 to implement the renovation, without changing the original diversion pipeline under the premise of the unit output increased from 1510kW to 2200kW. The application of modern design technology, the design of power plant dedicated turbine, appropriate to improve the new runner water capacity, the use of a variety of new technologies, new materials and new technology to make the unit more efficient than the original unit, water consumption is less than the original unit.
