BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary stowage induction device having a quake-resistant structure.

[0002]

2. Description of the Related Art There are dry type transformers, reactors, and the like as a board-incorporated static induction device, and conventional seismic structures thereof are shown in FIGS. In the figure, a stationary induction device body, for example, a three-phase transformer body 1 is shown as a rectangular box board 2
It is stored in.

The transformer body 1 is fixed on a transformer sub-base 3. The transformer sub-base 3 is, for example, I
It is configured by assembling shaped steel materials in a grid pattern, and between the transformer sub-base 3 and the transformer main body 1, from the four corners of the transformer sub-base 3 to the upper yoke iron core tightening of the transformer main body 1. Main support members 5 are provided so as to be coupled to the front and rear surfaces of both left and right ends of the fitting (upper clamp) 4, respectively.

In addition, in the illustrated example, since the transformer main body 1 is large, the interphase support member 6 is provided at the interphase position of the winding 1a of the transformer main body 1 from the transformer sub-base 3 as described above. It is provided so as to be connected to the upper yoke iron core fastener 4 of the transformer body 1. Further, a lateral support member 7 is provided so as to be coupled between the left and right sides of the main support member 5. The transformer sub-base 3 is fixed on the transformer-embedded base 9 which is embedded in the foundation portion 8 in advance by concrete or the like. Thus, the rigidity of the transformer main body 1 alone is increased, Seismic strength is secured.

On the other hand, the board 2 includes a reinforcing frame 10 as a top plate,
The side plates are reinforced. In addition, the board 2 is fixed on the board dedicated embedding base 11 which is installed in advance in the foundation portion 8 with concrete or the like, and thus the board 2 alone has increased rigidity, and the necessary seismic strength is secured. There is.

[0006]

As described above, in the conventional one, the seismic strength of the transformer body 1 is secured by the transformer body 1 alone, and the seismic strength of the panel 2 is secured by the panel 2 alone. There is. Therefore, the seismic structure is the transformer body 1 and the board 2
Was required for each and was complicated.

Further, since the transformer embedded base 9 and the panel embedded base 11 are separate structures, separate work is required to carry them in and install them, which requires a long construction period. . Furthermore, since the seismic structure and the base are required separately, the cost is high.

The present invention has been made in view of the above-mentioned circumstances, and therefore an object thereof is a board storage type static induction capable of simplifying the earthquake-resistant structure, shortening the construction period, and reducing the cost. To provide the equipment.

[0011]

According to this, since the board is fixed to the base and is supported by the supporting member via the inner reinforcing body, a large rigidity is secured. Then, the stationary induction device body is fixed to the base and is coupled to the inner reinforcing body so that it can be supported by the board through the inner reinforcing body, thereby ensuring a large rigidity. Thus, without applying a seismic structure to the stationary induction device body,
It is possible to secure the necessary seismic strength of the board and stationary induction device body. Also in this case, by fixing the stationary induction device body and the board on a common base, separate dedicated bases are not required for their installation.
