[0002] Three-phase three-column amorphous alloy cores are widely used in power transformers due to their excellent performance. These cores are particularly suitable for making transformers with Yy connection groups (e.g., Yyn0) and Dy connection groups (e.g., Dyn11). Their design makes the transformer's external dimensions more coordinated and aesthetically pleasing, with a small top-view projection area, thus giving it a significant advantage in terms of product structure economy.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Please see Figure 1-6 This utility model provides a three-phase three-column amorphous alloy core assembly structure, including an upper yoke plate 1 and a lower yoke plate 2. Skirt plates 3 are fixed to the sides of both the upper yoke plate 1 and the lower yoke plate 2. A base 4 is fixed to the bottom surface of the lower yoke plate 2. An upper hoop plate 5 is fixed to the upper yoke plate 1 by hexagonal bolts. A lower hoop plate 6 is fixed to the lower yoke plate 2 by hexagonal bolts. A fastening head 7 is fixed to the bottom of the upper hoop plate 5. A fastening groove 8 is provided on the top of the lower hoop plate 6. An upper E-type amorphous alloy core 9 and a lower E-type amorphous alloy core 10 are respectively arranged between the upper yoke plate 1 and the lower yoke plate 2.

[0028] The gap between the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 forms a slot 11, and the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 form a left window 12 and a right window 13. The upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 together form a three-phase three-column amorphous alloy core unit 14. Insert plates 15 are fixed at the bottom of the upper yoke plate 1 and the top of the lower yoke plate 2. By placing the upper E-type amorphous alloy core 9 with its opening facing down and the lower E-type amorphous alloy core 10 with its opening facing up, and then placing the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 alternately one in front of the other, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 can be quickly formed into a three-phase three-column amorphous alloy core unit 14, so that the three-phase three-column amorphous alloy core unit 14 can be wound with coils later.

[0029] Furthermore, the insert plate 15 is adapted to the slot 11. When the insert plate 15 is inserted into the slot 11, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are positioned between two adjacent insert plates 15, so that the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 can be clamped and fixed.

[0030] Furthermore, the upper E-type amorphous alloy core 9 has its opening facing downwards, while the lower E-type amorphous alloy core 10 has its opening facing upwards. Both the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are E-shaped. By having the upper E-type amorphous alloy core 9 facing downwards and the lower E-type amorphous alloy core 10 facing upwards, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 can form a left window 12 and a right window 13, so that the left window 12 and the right window 13 can be used to wind coils.

[0031] Furthermore, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are staggered. When the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are staggered, slots 11 can be formed at the upper and lower ends of the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10, so that each upper E-type amorphous alloy core 9 and each lower E-type amorphous alloy core 10 can be clamped and fixed by two adjacent insert plates 15.

[0032] Furthermore, the left window 12 and the right window 13 are located on the left and right sides of the three-phase three-column amorphous alloy core unit 14, which facilitates the winding of the coil through the left window 12 and the right window 13.

[0033] Furthermore, the fastening head 7 and the fastening groove 8 are fastened together by an internal hex bolt, which makes it easy to fasten the fastening head 7 and the fastening groove 8 together, thereby fastening the upper hoop 5 and the lower hoop 6 together.

[0034] Furthermore, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are located between the skirt plates 3 on the left and right sides, which facilitates the left and right fastening of the three-phase three-column amorphous alloy core unit 14 through the skirt plates 3 on the left and right sides.

[0035] Furthermore, the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are located between the upper hoop plate 5 and the lower hoop plate 6 on the front and rear sides, which facilitates the front-to-back fastening connection of the three-phase three-column amorphous alloy core unit 14 through the upper hoop plate 5 and the lower hoop plate 6 on the front and rear sides.

[0036] In use, the upper E-type amorphous alloy core 9 is positioned with its opening facing down, and the lower E-type amorphous alloy core 10 is positioned with its opening facing up. The upper and lower E-type amorphous alloy cores 9 and 10 are then placed alternately, one in front of the other, so that they are tightly pressed together. At this point, slots 11 are formed at the top and bottom of both the upper and lower E-type amorphous alloy cores 9 and 10. The alternating placement of the upper and lower E-type amorphous alloy cores 9 and 10 creates slots 11. The upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 together form a three-phase three-column amorphous alloy core unit 14. The upper yoke 1 is placed above the three-phase three-column amorphous alloy core unit 14, and the lower yoke 2 is placed below the three-phase three-column amorphous alloy core unit 14. The insert plate 15 is then inserted into the slot 11, so that the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 are respectively located between two adjacent insert plates 15. Therefore, the upper yoke 1, through the upper insert plate 15, can connect the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10. The top of the amorphous alloy core 10 is fastened, and the lower yoke 2, through the insert plate 15 below, can fasten the bottom ends of the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10. Thus, the insert plate 15 can quickly and tightly connect the upper E-type amorphous alloy core 9 and the lower E-type amorphous alloy core 10 to form a three-phase three-column amorphous alloy core unit 14. Then, the upper yoke 1 is fastened to the upper hoop plate 5 by hexagonal socket head cap screws, and the lower yoke 2 is fastened to the lower hoop plate 6 by hexagonal socket head cap screws. Finally, the fastening head 7 is fastened to the fastening groove by hexagonal socket head cap screws. 8. Tightening: The upper yoke plate 1 and the lower yoke plate 2 can be used to fasten the three-phase three-column amorphous alloy iron core unit 14 vertically. The skirt plates 3 on the left and right sides can be used to fasten the three-phase three-column amorphous alloy iron core unit 14 horizontally. The upper hoop plate 5 and the lower hoop plate 6 in the front and back directions can be used to fasten the three-phase three-column amorphous alloy iron core unit 14 in the front and back directions. Thus, the three-phase three-column amorphous alloy iron core unit 14 composed of the upper E-type amorphous alloy iron core 9 and the lower E-type amorphous alloy iron core 10 can be connected more stably.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
