Steel-making arc furnace transformer
1. Overview of EAF Transformer
The steel-making electric arc furnace transformer is a special transformer designed and manufactured according to the special requirements for the power supply produced by the electric furnace steel-making.
Second, the use of electric arc furnace transformer
Steel-making arc furnace transformers are used for smelting high-quality steel and alloy steel, aluminum silicate refractory fiber.
3. Structural characteristics of the electric arc furnace transformer
In addition to the characteristics of ordinary transformers, arc furnace transformers must also meet the special requirements of steelmaking processes, and have a certain overload capacity and short-circuit mechanical strength. The adjustment method of the arc furnace transformer is divided into two types: on-load voltage regulation and non-excitation voltage regulation. The on-load voltage-regulated arc furnace transformer does not have a series reactor. The structure of the arc furnace transformer without excitation and voltage regulation is divided into two types with series reactor and no series reactor. Both of these structures can change the impedance at very high secondary voltages. The former changes the impedance by the input and removal of series reactors, while the latter changes the impedance by changing the high-voltage winding connection of the arc furnace transformer itself.
