Abstract
PURPOSE: To reduce the shock given to an electric power system for releasing greatly by introducing compressed air into a runner chamber to lower the level of water and releasing a generatormotor from the electric power system.
CONSTITUTION: For stopping the operation of a water wheel pump, at first, a guide vane 6 is perfectly closed, and compressed air is supplied from a feed valve 9 for lowering the level of water in a draft tube 4. By this lowering, a runner 1 is exposed above water to be brought to a racing state, and the input to a generatormotor 3 is greatly reduced. This situation is detected by a draft-pipe water level detector 11 for releasing the generatormotor 3, and the shock given to an electric system for releasing is reduced greatly. In this construction, these devices are protected from the shortening of lives caused by the ordinary stopping of the operation of the pump.
