Due to the centrifugal force as a result of the shaft rotation speed, the spring is stretched further and further and the weight moves out. The set speed for operating the over speed trip can be adjusted by adding washers below the spring and then adjusting their compression pressure. WebOn older steam turbines the overspeed trip speed sensing and trip initiation was strictly by mechanical and hydraulic means with the key component being the mechanical overspeed trip device. Tripping of the turbine or any pump can lead to increase in the level of the surface condensor and the machine can trip on surface condenser level high. The protection system monitors steam turbine total train parameters and ensures safety and reliability by the following action: Start-up (optional) provides a safe, reliable fully automatic start-up and will shut down the turbine on any abnormality, Trip valve exerciser allows trip valve stem movement to be confirmed during operation without shutdown, Rotor overspeed monitors turbine rotor speed and will shutdown turbine when maximum allowable speed (trip speed) is attained, Excessive process variable signal monitors all train process variables and will shutdown turbine when maximum value is exceeded. #@Bw-O1mv:$hA$w eGkH-$^W_n WebElectronic Overspeed Protection for Gas Turbine Protection upgrade reduces stress on the gas turbine, reduces downtime and improves startup reliability Mechanical overspeed trip mechanisms require periodic overspeed testing that stresses rotating components, extends outages and can cause failed starts with the need for manual resets. Generally fitted on steam turbo alternators or generators, over speed trip prevents the engine from getting damaged because of extremely high speeds.
