在水电站轴流转桨式水轮发电机组的运行过程中,曾屡次发生随转动部分抬车而造成转轮叶片和其他部件损坏的事故。卡霍夫卡水电站的548—800型转桨式水轮机就曾在1956年发生过这样一次极为严重的事故。该电站在机组甩负荷时,转轮的三个叶片和一部分导叶被损坏,顶盖被冲掉,造成了淹没厂房的威胁。针对逆水流方向的力作用下所造成的转轮叶片损坏的
During the operation of Kaplan hydroelectric generating units in hydroelectric stations, accidental damage to the runner blades and other components caused by the rotation of some of the lift trucks has occurred repeatedly. An extremely serious accident occurred in 1956 in the 548-800 Kaplan Turbines at the Kakhhovka Hydropower Station. When the unit was subjected to load rejection, the three blades of the runner and a portion of the vanes were damaged and the top cover was washed away, threatening to inundate the plant. Against the direction of the water flow caused by the role of the rotor blades damaged
