Description
Woodward 8440-1706
Technical Specifications:
- Brand: Woodward
- Model: 8440-1706
- Product Type: Digital Synchronizer Module
- Dimensions: 144 mm × 72 mm × 122 mm
- Weight: Minimum 800 g (approx. 1.76 lbs)
Functional Features:
- Advanced Synchronization: Offers operators the choice of voltage matching, phase matching, or slip frequency synchronization during generator paralleling.
- Load and Power Management: Features real power control, true RMS power calculation, soft unload functionality, and adjustable power factor control.
- Operational Flexibility: Equipped with isolated operation control and dead bus operation features to ensure seamless grid integration.
- Local Diagnostics: Includes an integrated two-line LCD display for real-time system diagnostics, parameter adjustment, and alarm information.
Application Scenarios:
Widely deployed in power generation plants, marine propulsion systems, and industrial facilities requiring precise paralleling and load sharing of multiple generators.
Performance Parameters:
- Protection Level: IP42 (front panel) and IP24 (rear panel).
- Operating Temperature: -40°C to 70°C (with 95% humidity tolerance at 38°C).
- Storage Temperature: -55°C to 105°C.
Material Composition:
Housed in a rugged, industrial-grade enclosure designed to withstand severe electromagnetic interference, mechanical vibrations, and extreme temperature fluctuations.
Structural Features:
Standard industrial module form factor featuring a front-panel LCD interface, tactile navigation keys, and secure backplane connectors for reliable signal transmission.
Working Principle:
Continuously monitors the voltage, frequency, and phase angle of the incoming generator and the active bus. It calculates the precise closing time for the circuit breaker to achieve zero-crossing synchronization, preventing mechanical stress and electrical transients.
Installation Requirements:
Must be securely mounted in a standard control cabinet or rack. Requires proper grounding and adequate ventilation to maintain optimal operating temperatures.
Usage Precautions:
Ensure all synchronization parameters (slip frequency, voltage differential, phase angle) are correctly configured for the specific generator set. Regularly verify sensor inputs to prevent false synchronization.
