Overview
The WESTINGHOUSE 7379A62 is a legacy PC Control Circuit Board designed for turbine-generator control systems. It performs real-time processing of critical signals for turbine speed, load control, and protection. The board interfaces directly with high-speed sensors and QRT (Quadrature Resistance Transducer) inputs, which provide precise shaft speed and position feedback essential for synchronous generator operation.
Its reliability and industrial-grade design make it indispensable for continuous 24/7 operation in power plants, ensuring safe and stable electrical generation.
Technical Data
| Parameter | Specification |
|---|---|
| Part Number | 7379A62 |
| Component Type | PC Control Circuit Board / QRT Input Board |
| Operating Temperature | 0°C to +70°C |
Typical Applications
-
Steam and Gas Turbine Control: Manages electro-hydraulic valves for precise turbine speed and output regulation.
-
Generator Protection: Processes high-speed sensor data (speed, vibration, temperature) to detect unsafe conditions and initiate protective trips.
-
Load Management: Adjusts turbine output to match grid demand, maintaining stable frequency and voltage.
-
Synchronization: Ensures the generator is properly synchronized with the electrical grid before connection.
The board is critical for maintaining reliable operation of legacy turbine control systems, avoiding unscheduled downtime, and protecting costly plant assets.
FAQ
Q1: What does "QRT Input" mean for this board?
A1: QRT refers to Quadrature Resistance Transducer, a sensor that provides high-resolution shaft speed and position feedback. The 7379A62 processes these signals to maintain precise turbine speed regulation and protection logic.
Q2: Why is this legacy board still needed?
A2: Full control system upgrades are expensive and time-consuming. Using a replacement 7379A62 allows plants to maintain existing infrastructure safely and cost-effectively without major downtime.
Q3: What protection features are integrated?
A3: While protection logic is distributed, the board provides the high-speed processing and signal interface necessary for overspeed trips, fault monitoring, and noise filtering to prevent spurious shutdowns.
