Induction Furnace Rectifier Transformer for Copper Melting 1000kVA 10kv 0.66kv

Rectifier transformers face high operating currents combined with a huge amount of harmonic content due to the distrorted waveform caused by the semiconductor converters connected to the transformer. Typical applications are for : DC arc furnaces,electrolysis,scrap melting furnaces,aluminum smelter,graphitising furnaces.traction substatios, metal refining and inverters for variable speed drives.

 

Several solutions can be provided according to the rectifier features and the end -user need, Rectifier transformer is often coupled with components as regulating transformers(or autotransformers), saturable reactors and interphase transformers. All these components maybe assembled in one or in separate tanks.
