Resistance furnace transformer
Electric resistance furnace and salt bath furnace for heating, heat treatment of mechanical parts, powder metallurgy sintering, non-ferrous metal smelting, etc. Because the resistance of the heater is too small, or the resistance of the heater changes too much during the heating process, a resistance furnace transformer needs to be equipped between the furnace and the power grid to reduce and adjust the input voltage of the furnace.

The resistance furnace transformer and salt bath furnace transformer with small capacity and low voltage are mostly dry-type transformers, with a box shell and natural cooling; Resistance furnace transformers with medium capacity (hundreds to thousands of volt amperes) are mostly oil immersed self cooling transformers; Large capacity is forced oil circulating water-cooled transformer.


Electric arc furnace transformer
A Special transformer used to supply power to electric arc furnaces for iron and steel smelting. Large capacity, complex structure and high technical requirements. Its secondary side voltage is low, generally from tens of volts to hundreds of volts, and it is required to be adjustable in a large range; The secondary side current often reaches thousands to tens of thousands of amperes. In addition, in iron and steel smelting, large power is required during the melting period, and the transformer is required to have 20% overload capacity within 2 hours. In the process of steelmaking, electrode short circuit is easily caused by the collapse of furnace charge, so the primary side of the electric arc furnace transformer should be connected to the current limiting reactor in series or have a large impedance to limit the short circuit current.

Special transformer for intermediate frequency furnace
The special transformer for medium frequency furnace produced by the company is applicable to medium frequency electric furnace below 30 tons. The rated voltage at the primary side can be divided into 10KV or 35KV. The rated voltage of the secondary side can be divided into: 400V, 600V, 660V, 690V, 700V, 720V, 750V, 800V, 850V, 900V, 950V, 1000V, 1050V, 1100V, 1250V, etc. Rectification mode can be divided into 6 pulse, 12 pulse, 24 pulse or more. The current popular rectifier string, inverter string, rectifier parallel, etc
