うことにより水車の速度が設定値に保持されるよ
う制御する調速機において、水車の入口管に設け
た水圧検出器と、負荷しや断時及び非常停止時に
ガイドベーンを急閉鎖する際、前記水圧検出器が
検出する入口管の水圧が規定の最大水圧になる迄
はガイドベーンを大きな閉鎖速度で駆動するとと
もに最大水圧に達した後はこの最大水圧を越えな
いよう小さな閉鎖速度で駆動する制御手段とを有
することを特徴とする水圧検出制御調速機。 In the governor, which controls the speed of the water turbine to be maintained at a set value by opening and closing the guide vanes using a servo motor, there is a water pressure detector installed in the inlet pipe of the water turbine, and a water pressure detector installed in the inlet pipe of the water turbine, and in the event of load loss or emergency stop. When closing the guide vane suddenly, the guide vane is driven at a high closing speed until the water pressure in the inlet pipe detected by the water pressure detector reaches the specified maximum water pressure, and once the maximum water pressure is reached, the guide vane is driven at a high closing speed. 1. A water pressure detection control speed governor, characterized in that it has a control means for driving at a small closing speed.
