  • Protection system for turbo machine and power generating equipment
    Patent number: 7322788
    Abstract: A limit switch 6 is placed on an end portion of the trip rod 4, which converts the mechanical deviation of the trip rod 4 into an electrical signal. The electrical signal from the limit switch 6 is transmitted to quick acting solenoid valves placed in a drive unit for a steam valve via a sequence circuit device, and then the steam valve is closed. Accordingly, an equipment structure can be simplified and reliability can be improved as compared to conventional arts.
    Type: Grant
    Filed: June 8, 2006
    Date of Patent: January 29, 2008
    Assignee: Kabushiki Kaisha Toshiba
