Furnace Transformer BY Jindal Transformers

Furnace Transformer

The Induction Furnace features a coil made of heavy copper tubing, designed to work with an inverter circuit that applies medium-frequency voltage (typically 500 Hz or 1000 Hz) to generate heat through induced eddy currents in the charge. The inverter requires DC voltage, obtained by converting three-phase AC voltage using specialized transformers known as Induction Furnace Transformers. These transformers must endure high electrical, thermal, and mechanical stress due to frequent short circuits during the melting process. Unlike conventional transformers, furnace transformers are designed to handle high currents and frequent short circuits, ensuring reliable and efficient operation in demanding environments.

Induction Furnace Transformers are specially engineered to support high-performance melting operations in induction furnace systems. These systems utilize coils made of heavy copper tubing, powered by medium-frequency inverter circuits (typically 500 Hz or 1000 Hz) to generate heat through induced eddy currents in the charge.

To power the inverter, three-phase AC is converted into DC using dedicated furnace transformers. Unlike conventional transformers, Induction Furnace Transformers are designed to withstand extreme electrical, thermal, and mechanical stresses caused by frequent short circuits and heavy load fluctuations during the melting process. Their robust construction ensures reliable, efficient, and continuous operation in demanding industrial environments.
