The difference between electric furnace transformer and ordinary transformer

Electric Furnace Transformer
Resistance furnace and salt bath furnace used for heating, heat treatment, powder metallurgy sintering, non-ferrous metal smelting, etc. of Machine element. Due to the small resistance of the heating element or the significant change in resistance during the heating process, a resistance furnace transformer needs to be installed between the furnace and the power grid to reduce and adjust the input voltage of the electric furnace.
Small capacity, low voltage resistance furnace transformers and salt bath furnace transformers are mostly dry type transformers with box shells and natural cooling; Resistance furnace transformers with medium capacity (hundreds to thousands of VA) are mostly oil immersed self cooling transformers; The large capacity is a forced oil circulation water-cooled transformer.

Ordinary transformer

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It can be divided into: power transformer and Special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, Pressure regulator, Mine transformer, audio frequency transformer, intermediate frequency transformer, high-frequency transformer, impulse transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.) according to the purpose. The Electronic symbol often uses T as the beginning of the number. Example: T01, T201, etc.
