Reactance connecting device for transformer in electric arc furnace, has induction coil and standalone load switch for adjusting reactance of induction coil under load, where induction coil is provided with multiple tapping points
The device has an induction coil (1) and a standalone load switch (2) for adjusting the reactance of the induction coil under load. The induction coil is designed as a standalone heat insulated air-dielectric induction coil. The induction coil is provided with multiple tapping points (4), at which a winding of the induction coil is attached. The switch includes a set of input contacts (8), an output contact (10) and a switching unit (9) connecting one of the input contacts to the output contact. An independent claim is also included for a transformer including an additional device for adjusting the reactance.
