GE IC3600QOXC3 Overspeed Sensor Card

 

Turbines are designed to operate within a specific rotational speed range. If a turbine exceeds its maximum safe speed, a catastrophic failure can occur. The IC3600QOXC3 acts as a dedicated safety device. It receives signals from magnetic or eddy current speed pickups mounted on the turbine shaft. It then processes these signals to accurately calculate the rotational speed. If the calculated speed exceeds a predefined trip setting, the card sends a signal to the turbine’s trip circuit, which immediately closes the fuel and/or steam valves. This action is designed to be fast and reliable, operating independently of the main control system to ensure a safe shutdown even if the primary controls fail.

الوصف

The GE IC3600QOXC3 is an Overspeed Sensor Card for the GE Speedtronic Mark I and Mark II turbine control systems. Its primary function is to provide an independent, high-speed trip signal to shut down the turbine in the event of an overspeed condition.

Related Components

 

  • Speed Pickups: The card is wired to one or more speed sensors that generate a pulse signal with each revolution of the turbine shaft.
  • Trip Circuit: When the card detects an overspeed condition, it sends a signal to a series of relays that activate the trip circuit, cutting off the fuel or steam supply to the turbine.
  • Trip Relay Cards: The card communicates with other modules, such as trip relay cards, which control the physical actuators that close the fuel valves.
