Abstract

The invention relates to an amorphous alloy delta transformer core. The amorphous alloy delta transformer core is formed by vertically butting three identical core columns with upper and lower yokes, wherein the core columns are formed by winding amorphous alloy strips, and the cross section of each core column is circular; and the upper and lower yokes are identical triangular frames formed by winding amorphous alloy strips equal in width. A transformer manufactured from the amorphous alloy delta transformer core has the advantages of small iron loss, low noise, less material consumption, good short circuit impact property and the like.

Description

technical field

[0001] The invention relates to a transformer iron core, in particular to an amorphous alloy triangular transformer iron core. Background technique

[0002] Existing three-phase amorphous alloy transformer iron cores all adopt four-frame and five-column structures or three-frame and three-column structures, and the cross-section of the iron core columns is rectangular. In order to fit the transformer coil, each layer of the iron yoke at one end of the single-frame iron core needs to be disconnected to form an oblique seam. When assembling the coil, each layer of the iron yoke is opened one by one at the disconnection, and the coil is fitted on the iron core column. Then close them one by one, and glue the seams with special glue.

[0003] This iron core structure has many disadvantages. First, the rectangular cross-section of the iron core post consumes 11.4% more copper than the circular cross-section under the same number of coil turns; secondly, because o...

Embodiment Construction

[0009] As shown in the figure: the amorphous alloy triangular transformer core includes an iron core column, an upper iron yoke 4 located at the upper end of the iron core column and a lower iron yoke 5 located at the lower end of the iron core column, and the iron core column is made of the same It is composed of independent first iron core column 1, second iron core column 2 and third iron core column 3. Each iron core column has the same height and is formed by winding two or more amorphous alloy strips. Composed of cylindrical butt joints, each iron core column has a circular through hole in the center; the upper iron yoke 4 and the lower iron yoke 5 are the same, and are respectively wound by continuous amorphous alloy strips of equal width A triangular frame, the central holes of the upper iron yoke 4 and the lower iron yoke 5 are equilateral triangles, and the outer edges of the upper iron yoke 4 and the lower iron yoke 5 are equilateral triangles with rounded corners; t...
