Description:

Furnace transformer is power transformer which is used on industry furnace smelting, it’s a special transformer which is designed according to work principle, lead character and operation characteristic. It contains steel-making arc furnace transformer ladle refining furnace transformer, electro slag furnace transformer, submerged arc furnace transformer(ferroalloy furnace, calcium carbide furnace, phosphorus furnace and so on).all kinds of transformers which are use on alternative current furnace such as power frequency induction furnace transformer.

It has more stringent requirements in electric, magnetic, thermal, mechanical and other aspects compared with other transformers, and has to comply with the operation process of various furnace transformers and load characteristics, so that it can meet users, and facilitate energy-saving emission reduction and other conditions.

There are many kinds of furnace transformers. The company mainly produce the following products:

Features:

1.Wide range of voltage-regulate. Secondary voltage of differential voltage levels meets the arc furnace steel-making process requirements.

2.High-voltage has no restriction of switching insulation level, and it (e.g. 110kV) can be reduced to low-voltage directly, eliminating the intermediate substation and saving more than 30% invested.

3.Easy to choose suitable voltage-level load tap changer, economic and safe.

4.It can be accessed compensation capacitor in order to improve network power factor.

5.The main transformer works in constant flux density. Make full use of materials and have a good conservation.

6.Using the same reverse-phase parallel, electric (or magnetic) shielding, transposed conductors and so on to reduce losses and improve efficiency.

7.A separate voltage coil is used so that ampere-turn balance is good, coupled with cylinder pressure nail structure, its ability to withstand short-circuit is also increased and has high reliability.

8.Using third breaking off instead of primary breaking off so that it can be achieved with low price and high life of low-voltage circuit breakers instead of high price and low life of high-voltage circuit breaks.
