Induction Furnace
Induction Furnace
Voltamp Transformers Private Limited offers Induction Furnace. Induction Furnace has coil constructed from heavy copper tubing. It is designed and tuned to the inverter circuit, which applies a medium frequency (generally 500 Hz or 1000 Hz) voltage to the Induction coil. The magnetic field produced by the induction coil induces eddy currents in the charge and heats it. Medium frequency is necessary to enhance the rate of heat generation.
The inverter circuit requires for its operation a D.C. Voltage that is obtained by converting available three phase A.C. Voltage. Transformers, which are used, for transforming available three phase A.C. voltage to required voltage for converter circuit of the Induction Furnace are referred to as Induction Furnace Transformers. Thus they are essentially Rectifier/ Converter Duty Transformers.
Depending on the rating of the rectifier transformers, input voltage is derived from standard three phase AC distribution voltages like 433 V, 3.3 kV, 6.6 kV, 11 kV, 22 kV, 33 kV etc. These become the primary (or line side) voltage of the transformer. Secondary (or cell side) voltage can be between 400 to 1000 V decided by the required D.C. output Voltage.
