拔贡水电站改扩建工程水轮机的性能和结构特点

摘要

拔贡水电站改扩建工程安装2台10.5 MW灯泡贯流式水轮发电机组，转轮直径3.75 m。文中介绍机组的技术参数及结构特点，为小型灯泡贯流式水轮发电机组的设计、制造、安装积累了一定的经验，起到一定的参考借鉴作用。%The extension project of Bagong hydropower station installs two bulb tubular hydro-generating units with single capacity of 10.5MW and the runner diameter of 3.75m. The experiences on determining the unit technical pa-rameters and structural characteristics can be referenced by the design, manufacture and installation of small bulb hydro-generating units.
