換装置。 In a steam turbine in which a high pressure steam line is connected to the turbine high pressure section via a main steam control valve, an intermediate pressure steam line is connected to the turbine intermediate port, and a condensing device is connected to the turbine low pressure section, the high pressure section When the steam turbine is in a mode in which it is operated with high-pressure steam from the high-pressure steam boiler, the line is installed in the superheat prevention line connected between the high-pressure steam boiler and the high-pressure steam boiler. A steam turbine operation mode switching device comprising a switching valve with an electromagnetic valve that opens fully when the steam control valve is fully closed and switches the steam turbine to a mode in which the steam turbine is operated with intermediate pressure steam.
