Abstract
PURPOSE: To strengthen the explosion-proof function of a turbine by constituting a controller for the turbine such that an output of a rotation identifier for the turbine is converted into an electric signal and a final opening instruction is issued from an electricity to air converter depending on the outputs of the rotation identifier and an opening instruction signal arithmetic unit for a steam regulator valve.
CONSTITUTION: If the rotational frequency N of a turbine is changed, the back pressure P of a rotational frequency identifier 5 is also changed. This pressure is introduced into an air to electricity converter 8 and then is compared at an arithmetic unit 10 with a signal representative of a predetermined rotational frequency determined by a rotational frequency setting means 9 to provide an opening instruction electric signal which is converted into an air signal at an electricity to air converter 11. This air signal is applied to an air motor 13 by way of a magnet valve 24 and a compensator 12 to control a steam regulator valve 2. In case of a trouble in the electric circuit, the magnet valve 24 is closed to confine air between the magnet valve 24 and the air motor 13 and is locked to such position whereby runaway of the turbine 1 can be prevented.
