Protection system for a turbo machine |
摘要 |
<p>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.</p> |
