Title:
AMORPHOUS-ALLOY THREE-DIMENSIONAL WOUND CORE
Document Type and Number:
WIPO Patent Application WO/2023/232081
Kind Code:
A1
Abstract:
The present application relates to an amorphous-alloy three-dimensional wound core, comprising three single-frame iron cores, each of which comprises an inner support and a single-frame substrate, wherein the single-frame substrate is formed by winding an amorphous alloy strip onto the surface of the inner support; the inner support comprises a first support frame and a second support frame, a circumferential outer wall of the first support frame being configured such that the amorphous alloy strip is wound therearound, the second support frame being embedded in the first support frame, and the second support frame having a section thickness greater than that of the first support frame; and the outside of the single-frame substrate is coated with a plurality of adhesive layers, the innermost adhesive layer of the plurality of adhesive layers is coated in regions, and the hardness values of the plurality of adhesive layers can be adjusted according to requirements. In the above solution, the second support frame can support the first support frame, so as to facilitate an improvement in the overall structural strength of the single-frame iron core, thereby ensuring the straightness of a core column and improving the production quality of a transformer; and the surface of the single-frame substrate is coated with the adhesive layers, such that the supporting strength of the single-frame iron core is improved, iron core fragments are prevented from being scattered, and a noise reduction requirement is satisfied.
