Furnace Transformer with Oil Immersed Series Reactor

Series Reactor 

Brief Introduction:

  Series reactor normally used in transmission line to limit current, and for electric

 furnace to limit current and stabilizing electric arc. It can be made in air core type or silicon core type.

  Here we mean core type series reactor.

  

  Advantage to air type:

1. Long life as transformer 
2. Less work of maintenance 
3. Less environment pollution without EMD and no oxen resin
4. Less area or space
5. Less losses.

Main function and features

Furnace transformers are separated with normal power transformer with its characteristic of massive secondary currents which are the main products of VILLE Electric with many advantages both on quality and price. As an example a 30MVA unit at 150V would result in a secondary current of 115 kilo ampere. For these high secondary currents special bushings are required to be connected to the bus-bars. These bushings are specified with very specific arrangements to suit the bus-bar arrangement and cooling system. Furnace bus-bar are mostly water-cooled. The cooler are either of the oil forced (OFAF) or Oil forced water OFWF).


VILLE electric is renowned and appreciated by its reliable products performance and integrated services.

Application:

Arc furnaces are used in steel industry for smelting scrap iron and for refining steel.  Other application areas are :

1)    Smelting glass and ceramics

2)    Manufacturing or refining many other materials etc. ferrochromium, ferromanganese, different abrasive materials (oxides and nitrides), semiconducting base materials, nanopowders etc.

3)    Electric arc furnace (EAF) transformers are required for many different furnace processes and applications . they are built for :

a , Steel furnaces, mainly long arc

b, Landle furnaces

c, ferro-alloy furnace and similar with short or submerged are

d,Smelting of other materials
