Abstract

The invention provides an amorphous alloy transformer and a preparation method of an amorphous alloy strip. The amorphous alloy transformer comprises an amorphous alloy core and a coil, wherein the amorphous alloy core comprises a three-phase core, a single-phase core cover and a yoke; a stereoscopic triangle core structure is adopted by the three-phase core, the three-phase core comprises three single-phase cores and the single-phase cores are seamlessly connected; each single-phase core comprises a single-phase core limb and a yoke; each single-phase core limb and the corresponding yoke are connected end to end to form a closed rectangular frame and are isosceles trapezoids; each single-phase core limb is formed by superposing amorphous alloy strip post sheets; each yoke is formed by superposing amorphous alloy strip yoke sheets; and lateral extension cords of the amorphous alloy strip post sheets and the amorphous alloy strip yoke sheets all pass through the rectangular centers of the single-phase cores. Compared with the prior art, the amorphous alloy strip prepared by the preparation method of the amorphous alloy strip has the advantages that the saturation magnetization intensity, the rectangle ratio, the coercivity, the magnetic flux and the saturation magnetostriction are improved, and meanwhile, the core loss is reduced.

Description

technical field [0001] The invention relates to the technical field of amorphous alloy transformers, in particular to an amorphous alloy transformer and a preparation method for an amorphous alloy strip. Background technique [0002] To reduce the loss of the transformer and improve the efficiency of the transformer is to reduce the no-load loss and load loss of the transformer. The no-load loss in the transformer loss, that is, the iron loss, mainly occurs in the transformer core laminations, mainly due to the loss caused by the alternating magnetic field lines passing through the iron core to generate hysteresis and eddy current, while the load loss is mainly caused by the transformer winding Produced by the wire material in the coil. Mainly through the core structure, the development of iron core materials and the development of the manufacturing process technology of the amorphous alloy strip core, the production process of the iron core and the manufacturing technology...
