下卡马和契博克萨雷水电站水力设备的选择,首先是要求确定其装置方式有根本差别的最有效的机组型式——竖轴或横轴灯泡式机组。由于在大型竖轴转叶式水轮发电机组方面具有很多制造和运行经验,使得在设计和研究工作方面不需开支大笔补充费用,就能在短期间内制造和安装已经全面检验的竖轴机组。采用大直径和大容量的横轴灯泡式机组也是合理的,因为采用这种机组有可能缩短混凝
The choice of hydraulic equipment for the Kama and Chiboksare hydro-power stations starts with the first requirement to identify the most efficient type of unit - a vertical or horizontal axis light bulb unit, that has fundamental differences in the way it is installed. Due to the many manufacturing and operating experience in large vertical-axis vane-type hydrogenerator sets, the fully justified vertical axis can be manufactured and installed in a short period of time without significant expense in design and research work unit. The use of large diameter and large capacity horizontal axis bulb-type unit is also reasonable, because the use of such a unit may shorten the coagulation
