Main function and characteristic:
Electric furnace transformers are transformers which supply power to the electric furnaces. It can drop high
voltage to the working voltage the electric furnaces need.
There are many kinds of electric furnaces,so there are many kinds of electric furnace transformers cooperating
with them.Now,our company manufactures following electric furnace transformers:electric furnace transformers
used in steelelectric furnaces(including on-laod,no-load and enclosed reactor) ; mineral hot furnace
transformers used to smelt kinds of iron alloys,hydrosilicons,carbides,etc(single phase,three phases on-load
and no-load tap changer).They are low loss and energy-saving products.Cooling methods are self-cooling,
forced oil water cooling,etc.It can be designed specially according with customers' requirements.
The model of the electric furnace transformer is expressed as follows:
The meaning of model:
H--Steelmaking arc furnace,HJ--ladle furnace,HZ--electro-slag furnace,HC--calcium carbide furnace,HK--
mineral hot furnace,HG--line frequency induction furnace;
Number of phase:D--single phase,S--three phase;
Types of cooling device :ONAN,wind cooling F,water cooling S.
The methods of oil circulation:natural circulation,forced oilcirculation P.
Tap changer:off-circuit tap changer,OLTC Z.
Enclosed attached device:changing leakage flux,enclosed reactor K.
