6. Selection Recommendations
- Voltage/Current Needs: Match the 4.5 kV/3,500 A rating to system requirements; smaller applications may use ABB’s 5SHY25xx series.
- Environment: Ensure compliance with temperature (-40°C to +125°C) and altitude (up to 2,000 m) in the target installation.
- Scalability: Use stackable modules for systems exceeding 5 MW to maintain redundancy and simplify maintenance.
7. Precautions
- Installation: Torque mounting bolts to 15 N·m (avoid over-tightening to prevent mechanical stress).
- Cooling: Ensure adequate heat dissipation (recommended airflow: 5 m/s) for continuous operation at full load.
- Voltage Protection: Use snubber circuits (RC networks) to suppress voltage spikes and extend module lifespan.
- Storage: Store in dry conditions (≤30% humidity) and avoid exposure to direct sunlight or corrosive gases.
