Description
ABB SYN5201A-Z,V277 3BHB006714R0277
Technical Specifications:
- Order Code: 3BHB006714R0277.
- Model: SYN5201A-Z,V277.
- Voltage Rating: 277V (indicated by V277).
- Function: Automatic Synchronization and Check.
Functional Features:
- Precision Matching: Monitors voltage magnitude, frequency, and phase angle differences.
- Safe Closure: Issues close command only when all synchronization criteria are met.
- Dead-Bus Detection: Capable of detecting dead bus conditions for automatic transfer schemes.
Application Scenarios:
Critical for generator paralleling, bus-tie synchronization, and automatic transfer switch (ATS) applications in power plants and industrial facilities.
Performance Parameters:
- Accuracy: High-precision measurement of phase angle and frequency slip.
- Speed: Fast processing for timely breaker closure at the optimal moment.
Material Composition:
High-reliability electronic components housed in a robust, EMI-shielded enclosure.
Structural Features:
Standard rack or panel mount form factor with front-panel display and status indicators.
Working Principle:
Continuously compares the incoming source with the running bus, calculating the slip frequency and phase angle. When the predicted zero-crossing aligns with the breaker closing time, it issues the trip/close command.
Installation Requirements:
Connect voltage transformers (VTs) with correct polarity and phase sequence. Ensure proper grounding.
Usage Precautions:
Verify synchronization settings (angle, frequency, voltage tolerances) match system requirements. Never bypass synchronization checks during normal operation.
