Abstract

PURPOSE: To shorten a length of time required for closing the guide vane, by providing a driving mechanism for suppressing an opening operation command from a speed detector during a closing operation of the guide vane and making the closing operation continued of the guide vane.
CONSTITUTION: When a load is cut off during a water-wheel generating operation, with a guide vane closing command outputted and the guide vane closing, a rotational speed, lowering below the specified value, causes a speed detector to output an opening command of the guide vane. Therefore, at the same time of the load cut off from the water-wheel, until a position switch 27, for setting near to no- load opening degree, operates, with a load limiting device motor 12 driven to rotate a handle 11 in the closing direction, a valve 15 is lifted upward with a point 0 being the supporting point, to drain a pressurized oil through a tube F with a main valve 13 depressed down, and a piston 26 is shifted to the right side by a pressurized oil from a tube E, to close the guide vane. Accordingly, the guide vane continues a closing operation till a rotation of the motor 12 is stopped.
