Problems solved by technology
[0003] The three-dimensional wound iron core of amorphous alloy has the advantages of reasonable structure, good resistance to sudden short circuit, and low manufacturing cost. However, due to the influence of the characteristics of the amorphous material strip itself, it has the disadvantage of being sensitive to stress.

Abstract
The invention discloses an amorphous alloy three-dimensional roll core and a single frame thereof. The single frame comprises a single frame base body, and the single frame base body is formed by rolling of an amorphous alloy material strip around a central line. The single frame also comprises an elastic glue layer; the elastic glue layer comprises multiple glue areas; the glue areas are arrangedin a mutual spaced mode; and the coverage area of the elastic glue layer is no smaller than 40% of the surface area of the single frame base body. Thus, during a subsequent process of joining and assembling the single frames to the three-dimensional roll core, the external stress of the single frame base body is buffered, the sensitivity of the three-dimensional roll core to the stress can thus be reduced, and the magnetic performance of the three-dimensional roll core is enhanced.
Description
technical field [0001] The invention relates to the technical field of iron cores of transformers, in particular to an amorphous alloy three-dimensional wound iron core and a single frame thereof. Background technique [0002] The three-dimensional wound iron core of amorphous alloy is a typical iron core for making a transformer, including multiple (generally three) single frames arranged vertically around it. The vertical frame edge of each single frame is attached to the vertical frame edge of each single frame to form a stem for winding wires. [0003] The three-dimensional wound iron core of amorphous alloy has the advantages of reasonable structure, good resistance to sudden short circuit, and low manufacturing cost. However, due to the influence of the characteristics of the amorphous material strip itself, it has the disadvantage of being sensitive to stress. [0004] At present, how to reduce the stress sensitivity of the amorphous three-dimensional wound core has ...
