A Transformer with Amorphous Alloy Iron Core that Can Eliminate Eddy Current

Abstract

The invention relates to a transformer capable of improving transformer eddy current loss and discloses an amorphous alloy iron core transformer capable of effectively removing eddy current. The amorphous alloy iron core transformer comprises a coil framework wound with a coil winding, an iron core inserted into the coil framework, and a steel plate support used for mounting and supporting of all voltage transformation elements, the iron core is an E-shaped iron core made by amorphous alloy, the axis portion of the coil framework is hollow, a protruding portion of the iron core is inserted into the hollow portion of the coil framework, an aluminum sheet is embedded on the inner side of the steel plate support, and an eddy current opening is arranged at an area, perpendicular to leakage magnetic flux, of the side face of the steel plate support. The amorphous alloy iron core transformer solves the problem that existing transformers are serious in eddy current loss and can remove eddy current loss of a conductive shell and the iron core simultaneously.

Description

technical field [0001] The invention relates to a device for improving the eddy current loss of a transformer, in particular to an amorphous alloy iron core transformer which simultaneously eliminates the eddy current loss of a conductive shell and an iron core. Background technique [0002] A coil is wound outside a conductor, and an alternating current is passed through the coil, so that the coil generates an alternating magnetic field. Since the conductor in the middle of the coil is equivalent to a closed circuit in a circle in the circumferential direction, the magnetic flux in the closed circuit is constantly changing, so an induced electromotive force and an induced current will be generated in the circumferential direction of the conductor, and the direction of the current is along the circumference of the conductor The direction turns in a circle, just like a circle of vortexes. This phenomenon of electromagnetic induction in the whole conductor to generate induced ...
