Arc Furnace Transformer Overview

Steelmaking arc furnace transformer is a special transformer designed and manufactured according to the special requirements of power supply for electric furnace steelmaking.

Electric arc furnace transformer use

Used for smelting high-quality steel and alloy steel, aluminum silicate refractory fiber.

Structural characteristics of electric arc furnace transformer

In addition to the characteristics of ordinary transformers, arc furnace transformers must also meet the special requirements of the steelmaking process, with certain overload capacity and mechanical strength against short circuits. The adjustment methods of the arc furnace transformer are divided into on-load voltage regulation and non-excitation voltage regulation . The on-load regulated arc furnace transformer does not have a series reactor. The structure of the arc furnace transformer without excitation voltage regulation is divided into two types with and without series reactors. Both of these structures can change the impedance at the highest secondary voltage. The former changes the impedance by switching on and off the series reactor, while the latter changes the impedance by changing the high voltage winding connection method of the arc furnace transformer.
