Steel Shell Induction Melting Furnace

Electrical parts of the equipment include rectification transformer, low-voltage switch cabinet, intermediate frequency power cabinet, flat wave reactor, and compensation capacitor bank and water tank.

This equipment uses special-purpose rectification transformer, which transforms 35KV or the 10KV high voltage of the electrical network to 950V, which is suitable for the solid power.

There is a no-load manual changer at the high voltage side of transformer, output voltage can be adjusted at-5%, 0, +5%. It is used tosuit the deviation of grid. In order to ensure the safety of silicon-controlled rectifier and avoid impact on the grid, this transformer request the big short circuit resistance value 10%, simultaneously adds the shielding layer between the original and vice-coils. There are a gas relay and the oil thermometer on the power transformer, its output is chain-reacted with high-voltage switch cabinet, when there appears the gas alarm or higer oil temperature, it will automaticlly turn off the power.

Cooling of the Transformer uses the oil bath self-cooling.
