料として注目されている。N1, etc.) and semimetallic elements (B, 'CX5t, etc.), and has excellent magnetic properties with significantly lower iron loss and excitation current than conventional silicon value plates, making it an advantageous iron core. It is attracting attention as a material.
しかるに、非晶質磁性合金薄帯は、超急冷法によって製
造するために、その厚さは10oμ以下が普通である。However, since the amorphous magnetic alloy ribbon is manufactured by an ultra-quenching method, its thickness is usually 10 μm or less.

磁性材の優れた磁気特性を維持したまま鉄心を組立てる
ことが困難であるという問題がある。For this reason, when a wound core is constructed using an amorphous magnetic alloy ribbon, there is a problem in that since the ribbon is very thin, the core has low rigidity and easily loses its shape. Furthermore, when a compressive load is applied to the amorphous magnetic alloy ribbon in the thickness direction, the iron loss, which is an important factor in magnetic properties, increases by about 5 inches. Even when a wound core is manufactured from an amorphous magnetic alloy ribbon, windings are attached to the wound core in the same way as in the past, so the load is applied to the wound core as a compressive load. In other words, in the structure of the transformer contents in a conventional wound core type transformer, the self weight of the winding and the load of the winding are applied, so the iron loss of the amorphous magnetic alloy ribbon that makes up the wound core increases, and the There is a problem in that it is difficult to assemble an iron core while maintaining the excellent magnetic properties of the crystalline magnetic material.

Further, the lower end of the first portion 13a projects downward (from the lower surface of the lower silicate portion 11d of the wound core 1). This reinforcing part 12 is the leg part 1 of the wound core 11.
The legs 11b are disposed opposite to both sides of the leg 1a.
The reinforcing members 12 are arranged facing each other on both sides of the reinforcing members 12, and are fixed by binding the joints 11m and 11bK with tape such as glass fiber tape. In the figure, reference numeral 16 denotes a pair of upper fasteners provided on both sides of the upper silicate part 11c of the wound core 11. As shown in FIG. The upper silicate part 11 has a part that abuts along the horizontal direction and a part that covers the upper part.
It has a long length. On the lower side of the upper fastener 16, a silicate support part 17 is formed along the horizontal direction, which contacts the lower side of the upper silicate part 11c of the wound core 11, that is, the side surface of the core window. Note that boss holes 16a are formed at both ends of the upper fastener 16, respectively. The upper fasteners 16 are disposed on both sides of the upper silicate part 11c, and both ends of each upper fastener 16 extending from both ends of the upper silicate part 11e and facing each other are connected to a delt 18 and a nut 19. The tightening is fixed. Therefore, the upper fastener 16 tightens and fixes the upper silicate part 11'c from both sides. Note that a groove 15 is provided at the upper end of the first portion 13a of the presser part 13.
Is the upper fastener 16? It engages with the slot 16a. 20 in the diagram

It protrudes downward from the bottom surface and is fixed to the bottom wall of the transformer tank (not shown). Note that the reinforcing member 12O leg holding part 13 and the lower fastener 20 protrude downward from the lower iron part fed of the wound core 11 to hold the wound core 11, so that the wound core 11 has a gap from the bottom wall of the transformer tank. and are held at a distance.

11a。Therefore, in the inside of the transformer, the reinforcing member 12 is attached to the wound core 1, and the reinforcing member 12 and the upper fastener 16
and a lower fastener 20 are mechanically coupled. The pressing portion 13 of each reinforcing member 12 is the leg portion 11a of the wound core 11.
11bを囲んで側方から押えているので、脚部IVIL

るので、巻鉄心11をいわば首吊シ状態で保持できる。Since the winding support part 14 of the reinforcing member 12 supports the winding 21 from below, the structure is such that the load of the winding 21 attached to the legs 11a and llb is not applied to the legs 11a and llb of the wound core 11. There is. In addition, the silica support portion 1 of the upper fastener 16
7 abuts and supports the upper silicate portion 11c of the wound core 11 from below, and the reinforcing member 12 holds the upper fastener 16, so that the wound core 11 can be held in a so-called hanging state.

Then, the reinforcing member 12 and the lower clamping tool 2 are attached so that the wound core 11 is held in a state where the lower surface of the lower opening part lid is spaced apart from the bottom wall of the transformer tank with a spacing.
The connection dimension relationship with 0 is set. In this way, the core 11 can be held in a hanging shape.
