Spare Parts Supply for SAF Short Network System
The short network is a core component of the power supply system in submerged arc furnaces (SAF). It connects the secondary terminal of the transformer to the electrode copper shoe, undertaking the critical task of transmitting high-current electrical energy into the furnace. The design and manufacturing quality of the short network directly affect the power efficiency, three-phase balance, and operational stability of the SAF.
1. Definition
The short network refers to all conductors from the secondary terminal of the furnace transformer to the electrode copper shoe (heating terminal). It is named for its short transmission distance (typically only a few meters to over ten meters)
2. Specifications and Parameters
| Parameter | Specification Range |
|---|---|
| Cross-section Shape | Circular / Rectangular |
| Rectangular Section Size | Depends on the current level |
| Center Phase Spacing | Around 30mm |
| Outer Phase Spacing | Around 5mm |
| Resistivity | 0.0175 Ω·mm²/m (20℃) |
3. Key Supporting Components
| Component | Description |
|---|---|
| Compensator | Connects transformer to fixed copper tube, absorbs thermal expansion and installation errors; Type A, B, C connectors available |
| Conductive Copper Tube | Fixed section copper tubes, multiple parallel connections, rectangular cross-section reduces reactance |
| Water-Cooled Cable | Connects fixed copper tube to movable furnace copper tube; flexible and bendable to accommodate electrode lifting |
| Cable Management Mechanism | Clamps, fixing grooves, adjustment sleeves, etc., prevent cable tangling and reduce water flow resistance |
| Insulation Clamp | Fixes multiple copper tubes, maintains consistent spacing, prevents short circuits |
| SAF Capacity | Recommended Configuration | Selection Reason |
|---|---|---|
| Small Furnace (<12500kVA) | Circular Cross-Section Copper Tube + Braided Water-Cooled Cable | Lower cost, meets basic requirements |
| Medium Furnace (12500-35000kVA) | Rectangular Cross-Section Copper Tube + Braided/Stranded Cable | Reduces reactance, improves efficiency |
| Large Furnace (35000-81000kVA) | Rectangular Cross-Section Copper Tube + Low Impedance Design + LV Short Network Compensation | Pursues optimal energy saving effect |
| Ultra-Large Furnace (>81000kVA) | Equilateral Triangle Transformer Arrangement + LV Short Network Compensation | Three-phase balance, reduces line losses |
Notes:1. Rectangular cross-section copper tube reduces phase spacing, increases mutual inductance, and lowers reactance; cut-surface adjacent arrangement provides optimal effect
2. Insulation treatment must be enhanced when short network spacing is reduced to prevent short circuit accidents
3. Ensure cooling water flow rate and water quality meet requirements to prevent scaling and blockage
4. Conductive tube temperature inside the furnace is 300-400℃ higher than outside, requiring larger cross-section or enhanced cooling
