Embodiment 1

[0032] use Figure 1~6 , to illustrate Embodiment 1 of the present invention. exist figure 1 , figure 2 The body structure of the transformer of Example 1 is described in . figure 1 is the front view, figure 2 is a side view. The body structure of the transformer of the present invention includes an iron core 100 , a coil 200 , an upper fastening metal part 300 , a lower fastening metal part 400 , an iron core fixing metal part 500 , a fastening metal part tightening bolt 600 , and a base 700 . The iron core fixing metal fitting 500 is a cylindrical member having a quadrangular cross-section surrounding the laminated iron core 100 and is disposed so as to pass through the coil 200 . In addition, the iron core 100 arranged in the iron core fixing metal fitting 500 is fixed by tightening the upper fastening metal fitting 300 and the lower fastening metal fitting 400 with the fastening metal fitting tightening bolt 600 . Furthermore, the core fixing metal fitting 500 is f...

Embodiment 2

[0051] Figure 7 A front view of the iron core 100 in the second embodiment of the present invention is shown. with the first embodiment Figure 3d Similarly, two core laminates such as core materials 107 and 108 , 101 and 102 , and 104 and 105 are arranged side by side, and a first laminate block and a second laminate block are laminated. The difference from the first embodiment is that the material widths of the core materials 107 and 108 are different from each other. Similarly, 101 and 102, 104 and 105 also have different material widths. In the central core part of the three-legged core legs, laminated blocks of the core material 110 having a small material width and laminated blocks of the core material 111 having a large material width are arranged side by side, and they are similar to those of the first embodiment. The examples are similarly stacked with right and left reversed for each stacked block. In the case of the second embodiment, the core material 111 havi...

Embodiment 3

[0057] Figure 8 A front view of the iron core 100 in the third embodiment of the present invention is shown. with the first embodiment Figure 3d and the second embodiment Figure 7 Similarly, two core laminates such as core materials 107 and 108 , 101 and 102 , and 104 and 105 are arranged side by side, and a first laminate block and a second laminate block are laminated. In this embodiment, the core materials 110 and 111 constituting the central core leg have the same width, while the core materials 107 and 108 constituting the outer core legs, the core material 101 and the Reference numeral 102 designates different core widths from each other. The central core leg is composed of two types of wide cores constituting the outer core leg. Iron core foot is big. Since the core leg in the center is sandwiched between the core legs and the coil 200 on both sides, it is easy to trap heat, but it is difficult to cool down compared to the core legs on both sides. When the iron...

Abstract

It is difficult to easily manufacture a large-capacity transformer with a laminated core structure using an amorphous alloy material. It is characterized in that it includes: a laminated iron core, which is formed by arranging a plurality of laminated iron core blocks formed by laminating iron core materials in a direction different from the lamination direction; and a first frame body along the outer periphery of the laminated iron core ; and a spacer plate arranged between a plurality of laminated iron core blocks.

Description

technical field [0001] The present invention relates to a laminated core structure and a transformer including the laminated core structure. Background technique [0002] The core structure of a transformer is roughly divided into a wound core and a laminated core. Wound cores are mainly used in distribution transformers, and stacked cores are used in small transformers for power electronics or large-capacity transformers with larger capacity than distribution transformers. The core materials of transformers include silicon steel plates and amorphous alloys. An amorphous transformer using an amorphous alloy as a core material has lower no-load loss than a silicon steel plate transformer using a silicon steel plate as a core material, and is known as a transformer with high energy consumption efficiency. [0003] In recent years, large-capacity transformers using amorphous alloys with good energy consumption efficiency have been desired. However, conventionally, it has been...
