Ⅰ. Mga Pangangailangan ng Scenario at Teknikal na Hamon
- Katugma sa Grid: Ang industriyal na grid ng Mehiko ay nag-ooperate sa 480V/60Hz (3-phase), habang ang inilahok na kagamitan (halimbawa, Italian baking lines) nangangailangan ng 380V/50Hz, na nagdudulot ng dual voltage at frequency mismatches.
- Reliabilidad ng Kagamitan: Ang mahigpit na kapaligiran ng bakeshop (hanggang 45°C, 70% humidity) nangangailangan ng ANSI-compliant distribution transformers na may kakayahan ng high-temperature resistance at moisture-proof upang maiwasan ang insulation failure at downtime.
- Enerhiya Efficiency: Ang mga production lines ay kasama ang maraming mataas na lakas na motors (≥75kW per unit), na kinakailangan ng reduced no-load losses sa distribution transformers upang minimisuhin ang pangkalahatang enerhiya consumption.
Ⅱ. Solusyon ng Rockwell's ANSI-Compliant Dry-type Distribution Transformer
Paggamit ng Core Equipment
Modelo: SCB13 three-phase dry-type distribution transformer (UL 5085-1 certified, aligned with ANSI safety standards).
Teknikal na Parameters:
- Rated Capacity: 800kVA (1.23x redundancy para sa 650kW total load).
- Voltage Conversion: 480V±10% → 380V±2% (dynamic voltage stabilization).
- Frequency Compatibility: 50/60Hz auto-switching (wide-frequency magnetic core).
- Insulation Class: H-grade (180°C tolerance, 3000V/min withstand test).
- Protection Rating: IP54 (dust/waterproof for workshop conditions).
Mga Key Technical Features
1. Mataas na Epektibong Conversion
- AMorphous alloy core reduces no-load losses by 35% (≤0.15% vs. traditional silicon steel).
- 12% mas malaking copper winding cross-section ensures ≥98.5% full-load efficiency.
2. Adaptability sa Kapaligiran
- Epoxy resin vacuum casting (72-hour salt spray test) protects ANSI-compliant distribution transformers from moisture.
- Forced-air cooling enables continuous operation at 55°C ambient temperature.
3. Smart Monitoring
- ±1°C accuracy thermal sensors monitor winding hotspots.
- Modbus RTU integration with SCADA enables predictive maintenance.
