SCB series dry type transformers refer to transformers in which the core and windings are not immersed in insulating oil. The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50% in short time.
| Model | Rated capacity (KVA) | High Voltage (KV) | Low Voltage (KV) | No-load loss (W) | Load loss (W) | Short circuit impedance (%) |
|---|---|---|---|---|---|---|
| SC(B)10-30 | 30 | 10, 10.5, 11 | 0.4 | 190 | 710 | 4 |
| SC(B)10-100 | 100 | 10, 10.5, 11 | 0.4 | 400 | 1570 | 4 |
| SC(B)10-400 | 400 | 10, 10.5, 11 | 0.4 | 980 | 3990 | 4 |
| SC(B)10-1000 | 1000 | 10, 10.5, 11 | 0.4 | 1770 | 8130 | 6 |
| SC(B)10-2500 | 2500 | 10, 10.5, 11 | 0.4 | 3600 | 17170 | 6 |
1. Iron core: Stacked silicon steel sheets forming the magnetic circuit.
2. Winding: High-voltage and low-voltage windings for energy conversion.
3. Insulating cylinder: Increases electrical insulation between coils.
4. Pads: Support and maintain coil stability and shape.
5. Fasteners: Ensure all parts are securely fixed with anti-loosening performance.
