本文介绍了法国的一台可调节的两级水泵—水轮机大规模试验的结果。文中分别从机组总体的布置及主要部分(蜗壳、导水机构、转轮)、样机的试验情况、发电运行工况、水泵运行工况、制动水泵的试验、反向水泵旋转试验等方面进行了论述,它为发展大功率的两级可调节的水泵—水轮机、装置运行水头高于1000m的抽水蓄能电站提供了依据。 This article presents the results of a large scale pilot test of an adjustable two-stage pump-turbine in France. This paper respectively from the unit’s overall layout and the main part (volute, water guide mechanism, runner), prototype test conditions, power generation operating conditions, pump operating conditions, brake pump test, reverse pump rotation test and so on It provides the basis for the development of high-power two-stage adjustable pump-turbine and pumped storage power plant with head running above 1000m.
