座9,9が取付けられている。(Prior Art) As a transformer installed in a building, its capacity tends to increase due to automation of air-conditioning equipment, lighting equipment, other equipment, and installation of various office equipment. High-pressure and large-capacity ones have been used. On the other hand, it is desired to reduce the installation area in order to facilitate the loading of transformers and effectively utilize the floor space of the building. For this reason, conventionally, it is considered that a plurality of small-capacity wound core type transformers are stacked and used instead of installing one large-capacity transformer. This is shown in FIGS. 8 to 11. That is, the wound iron core type transformer 1 is composed of a transformer main body 2 including a wound iron core 2a and a coil 2b, and a support frame 3 supporting the transformer main body 2. The support frame 3 includes a lower frame 4 having a U-shaped cross section, side frames 5 and 5 extending upward from both ends of the lower frame 4, and side frames 5 and 5 thereof.
The upper frame 6 is hung between the upper ends of the upper frame 6 and the nut 8 is screwed between the side frames 5 and 5 and the upper frame 6 to the bolt 7 penetrating the insertion holes 5a and 6a. Are linked together. Fixing seats 9, 9 are attached to both ends of the bottom of the support frame 3.
而して、この変圧器1の上部にこの変圧器1よりも小
容量の上段の変圧器を段積みする場合には、その上段の
変圧器支持枠の左右の長さ寸法は変圧器1の上部枠6の
長さ寸法より充分に小であるので、そのまま上段の変圧
器を上部枠6の上面部に載置して固定することができ
る。Therefore, when stacking an upper-stage transformer having a smaller capacity than this transformer 1 on the upper part of this transformer 1, the left and right length dimensions of the upper-stage transformer support frame are the same as those of the transformer 1. Since it is sufficiently smaller than the length of the upper frame 6, the upper transformer can be mounted and fixed on the upper surface of the upper frame 6 as it is.
しかしながら、上記変圧器1の上部にこの変圧器1と
同一容量,同一構成の上段の変圧器を段積みする場合に
は、上段の変圧器の支持枠の左右の長さ寸法は変圧器1
のそれと同等であるので、このままでは固定用座(固定

側部枠5,5の上端部に夫々嵌合固着し、これらの取付部1
0a,10aに上段の変圧器の固定用座(固定用座9,9に相
当)を固着するようにしている。However, when stacking an upper-stage transformer having the same capacity and the same structure as the transformer 1 on the upper part of the transformer 1, the left and right length dimensions of the support frame of the upper-stage transformer are the same as those of the transformer 1.
Since it is equivalent to that of the above, the fixing seat (corresponding to the fixing seat 9, 9) cannot be placed on the upper surface portion of the upper frame 6 as it is. Therefore, in such a case, as shown in FIG. 11, the connecting members 10 and 10 composed of the horizontal mounting portion 10a and the vertical piece portion 10b attached to the lower surface portion of the mounting portion 10a are attached to the support frame 3 The side frames 5, 5 of the
The fixing seats (corresponding to the fixing seats 9 and 9) of the upper transformer are fixed to 0a and 10a.

あり、コスト高になるという問題点がある。(Problems to be Solved by the Invention) In the above-mentioned configuration, when a transformer having the same capacity as the lower transformer 1 is stacked, the side frame of the support frame 3 is used.
Since the connecting members 10, 10 must be fitted and fixed to the upper ends of the 5, 5, respectively, the number of parts increases and the number of assembling steps also increases. Also, when stacking transformers having a smaller capacity than the lower transformer 1, the weight of the upper transformer will be applied to the upper frame 6, and as shown in FIG. Since a remarkably large concentrated stress σ1 is generated at the contact point of the insertion hole 6a with the bolt 7, it is necessary to increase the wall thickness of the upper frame 6 or increase the number of bolts 7, resulting in high cost. There is a problem.

とで受けるので、集中応力を小になし得る。(Operation) According to the wound core type transformer of the present invention, the upper frame member is coupled to the upper ends of the pair of side frame members so as to be addressed from the outside. The length dimension can be arbitrarily set without being restricted by the left and right length dimensions of the bottom frame member, that is, the left and right spacing dimensions of the pair of side frame members, and therefore, another transformer is stacked in particular. In this case, since it can be placed on the upper frame member that is addressed from the outside between the upper ends of the pair of side frame members, no dedicated parts such as a connecting member are required. Further, since the weight of the upper transformer is received by the rectangular fitting hole formed in one of the upper frame member and the side frame member and the rectangular fitting protrusion provided in the other, , The concentrated stress can be reduced.

鉄心形変圧器23が構成される。Now, the rectangular fitting protrusions 21, 21 are attached to the side surface of each upper frame member 16 by welding, and the upper frame member 16 is applied from the outside between the upper ends of the side frame members 14, 14. At this time, it is fitted into the rectangular fitting hole 22 formed in the upper end of the side frame member 14. A wound core transformer 23 is composed of the transformer main body 11, the lower frame member 13, the pair of side frame members 14, 14 and the pair of upper frame members 16, 16.

Two fixing seats 15 for each of the upper transformers 23 on the upper surface of the 16, 16
Then, a nut (not shown) is screwed onto the fixing bolt 24 inserted through the hole 15a and the outer hole 20.
尚、変圧器23にこれよりも小容量の変圧器を段積みす

及び嵌合孔22の数を増加させる必要がなく、コスト高に
なることを防止できる。According to the above-mentioned example, the following effects are produced. That is, since the pair of upper frame members 16, 16 are arranged so as to be addressed from the outside between the upper ends of the pair of side frame members 14, 14, the left and right length dimensions of each upper frame member 16 are the bottom. It can be arbitrarily set without being restricted by the left and right length dimensions of the frame member 13, that is, the left and right spacing dimensions of the pair of side frame members 14, 14. Therefore, it is possible to stack the upper transformers 23 on the upper surface portions of the upper frame members 16 and 16, and it is possible to prevent an increase in the number of parts and the number of assembling steps unlike the conventional case in which the dedicated connecting member 10 is required. In this case, the weight of the upper transformer 23 is received at the lower contact portion between the fitting protrusion 21 of the upper frame member 16 and the fitting hole 22 of the side frame member 14 (see FIG. 6). ), Since these are rectangular, the lower contact portion becomes linear and the concentrated stress σ2 becomes extremely small, so the thickness of the side frame member 14 and the upper frame member 16 is increased. No need, and the mating protrusion 21
Also, it is not necessary to increase the number of fitting holes 22, and it is possible to prevent the cost from increasing.

応力は小になる利点がある。By the way, in the case where the two transformers 23, 23 are hoisted in a stacked state, the total weight is, contrary to FIG. 6, the fitting projection 21 of the upper frame member 16 and the side frame. The upper contact portion of the member 14 with the fitting hole 22 receives the upper contact portion. However, since they are also not rectangular, there is an advantage that the upper contact portion is linear and the concentrated stress is small.

要旨を逸脱しない範囲で種々の変形が可能である。The present invention is not limited to the embodiment described above and shown in the drawings. For example, the upper frame member 16 is provided with the fitting protrusion 21 and the side frame member 14 is formed with the fitting hole 22. However, the side frame member 14 may be provided with a fitting protrusion to form the fitting hole in the upper frame member 16, and the pair of upper frame members 1 may be provided.
6, 16 are arranged between the upper end portions of the pair of side frame members 14, 14, but instead of this, the upper frame member having a U-shaped cross section may be straddled from above the pair of side frame members 14, 14. May be installed in the
Various modifications are possible without departing from the gist.
