一、概述混流武水轮机单机容量四十年代初才突破10万千瓦,达到这一水平差不多化了近一个世纪。至五十年代末单机容量已超过20万千瓦。六十年代开始由于科学技术的迅速发展,混流式水轮机的单机容量有飞速的发展。1967年苏联在克拉斯诺雅尔斯克投产了第一台50万千瓦的机组(水轮机的出力为50.8万千瓦)。 I. Overview The unit capacity of Francis Wupower turbines exceeded 100 thousand kilowatts at the beginning of 1940s, reaching almost the same level for nearly a century. By the end of the fifties, stand-alone capacity had exceeded 200,000 kilowatts. Since the 1960s, with the rapid development of science and technology, the stand-alone capacity of Francis turbines has been rapidly developing. In 1967 the Soviet Union put into operation the first 500,000-kilowatt unit in Krasnoyarsk (the output of the hydro-turbine was 508,000 kilowatts).
