Abstract
The utility model relates to a three-phase and three-column type amorphous alloy iron core, comprising an iron core main body formed by an outer amorphous iron core frame and two adjacent inner amorphous iron core frames positioned in a central hole of the iron core frame, wherein arms at the inner sides of the two inner amorphous iron core frames are adjacent; the arms at the outer sides of the two inner amorphous iron core frames are respectively adjacent to the two arms of the outer amorphous iron core frame; three adjacent arms form three core columns of the iron core main body respectively; the front side surface and the rear side surface of each core column are respectively bonded with a supporting steel plate; the outer sides at the lower parts of all the supporting steel plates on the same front and rear side surfaces are horizontally and fixedly connected with the same C-type supporting steel plate; and the horizontal edge of the C-type supporting steel plate extends outwards. Since a split type support steel plate is adopted, even though the amorphous iron core is used on a large-capacitance transformer, the quality of the supporting steel plate can be easily ensured, and the processing difficulty of the supporting steel plate is greatly reduced. In addition, since the C-type supporting steel plate is arranged, the whole strength of the iron core is further improved.

Described supporting steel plate can be provided with some through holes, can adopt epoxy bond together between described supporting steel plate and the described stem.
The surface that described supporting steel plate and described stem fit can be coated with coating insulation material.
The outside, bottom of described each supporting steel plate on the same forward and backward side can crosswise fixed connect same C type supporting steel plate, and the horizontal edge of described C type supporting steel plate stretches out.
Described each amorphous core frame can be made up of a monomer unshakable in one's determination or a plurality of monomer unshakable in one's determination, when form same amorphous core frame be a plurality of monomer unshakable in one's determination the time, the side of described a plurality of monomers unshakable in one's determination can bond together mutually.
The beneficial effects of the utility model are:
Owing to adopted split type supporting steel plate, the area of monolithic supporting steel plate reduces significantly, the difficulty of processing of supporting steel plate and the difficulty of coating operation have greatly been reduced, improve the utilance of material, reduced waste of material, saved the production cost of supporting steel plate, also improved the evenness of supporting steel plate simultaneously, improved bond effect, especially for high-power transformer for amorphous core, this effect is more obvious.In addition, because the outside, the bottom of the several split type supporting steel plates on the forward and backward same side of main body unshakable in one's determination crosswise fixed connects same C type supporting steel plate, further improved bulk strength unshakable in one's determination.
