Abstract

PURPOSE: To quickly stop a water wheel generator in the trouble of a control hydraulic system and prevent an accident, by detecting the disappearance of oil pressure from the hydraulic system and shutting off a servomotor.
CONSTITUTION: When pressure oil or oil pressure in a tank 3 disappears or abnormally decreases due to the trouble of the control hydraulic system, an oil detector 7 or an oil pressure detector 8 detects the disappearance or the abnormal decrease to actuate a protector 9. Emergency shut-off valves 10, 11 for an input and an output outlet passages of opening and closing oil for the servomotor 5 are closed by the output of the protector 9. At the same time, an emergency pump 12 is started to transfer the pressure oil of the cylinder of the servomotor 5 from the open side to the closed one in the direction of the arrow in Fig. to shut off the servomotor. A guide vane control mechanism 6 is thus actuated in a feed water control direction to quickly stop a water wheel.
