1T induction melting furnace transformer selection method
The electrical part of 1T induction melting furnace includes: power rectifier transformer (optional), intermediate frequency power cabinet, compensation capacitor bank.
1. Power rectifier transformer selection method :
The power rectifier transformer is used to reduce the 1OKV high voltage of the power grid to a voltage suitable for the intermediate frequency power supply. The IF equipment uses a dedicated rectifier transformer, and the oil is immersed in the self-cooling mode.
2. Parameters of the rectifier transformer:
Electric furnace capacity (t) | IF power (KW) | Transformer capacity (KVA) | Voltage combination | Connection group label |
Impedance voltage (%) | |
Primary side (KV) | Secondary side (V) | |||||
1 | 1000 | 1250 | 10 | 380 | Y, d11 | 6-8 |
Note: There should be no load regulating switch on the high voltage side of the transformer, and the voltage is adjusted in the third gear of -5%, 0, +5%.
