10kV/35kV Electric Furnace Transformer

Overview

Electric furnace transformers are  mainly  used  in  resistance furnaces  and  salt  bath furnaces for  heat treatment of mechanical parts, powder metallurgy sintering, nonferrou  metal smelting, etc. , and can  also  be  used  as  power  transformers  for  steel    making  electric  arc  furnaces. The  capacity  of  electric  furnace  transformers  is  configured  according  to  the  size  of  the  electric  arc furnace  and the smelting  process. It  meets  the  requirements  of  the  smelting  process  by  means  of  voltage  regulation.

There  are  two  types  of  voltage   regulation:on-load  voltage   regulation  and   non-excitation  voltage   regulation. Large-scale electric  furnace  transformers  with  on-load  voltage  regulation  do  not  have  series  reactors, and  small  and  medium-sized electric furnace  transformers without  excitation  voltage  regulation  can  be  divided  into  two  types  with  series  reactors  and those without  reactors. The  former  relies  on  the  input  and  removal  of  the  series  reactor  to  change  the  impedance. The  latter changes  the winding  impedance  by  changing  the  connection  method  of  the  high-voltage  winding  of  the  furnace  transformer itself.

Electric furnace transformers are specialized transformers designed based on the working principles, load characteristics, and operating features of various electric furnaces. Specifically, they include transformers for various AC electric furnaces such as steelmaking electric arc furnaces, ladle refining furnaces, electroslag furnaces, submerged arc furnaces, and power frequency furnaces, as well as transformers for DC electric furnaces such as medium-frequency induction furnaces, silicon carbide furnaces, and graphitization furnaces.

Industrial electric furnace transformers are mainly divided into three categories: resistance furnace transformers, electric arc furnace transformers, and induction furnace transformers.
