Description

[Detailed Description of the Invention] This invention relates to an improvement of a cable storage box, ie, an elephant, provided at the input and/or output side of electrical equipment such as transformers and reactors.

In FIG. 1 showing a conventional electric device with an elephant, 1 is an electric device such as a transformer or a reactor, 2 is a bushing that is an input/output terminal of the electric device 1, 3 is a cable, 4 is an elephant, and 5 is a bushing that is an input/output terminal of the electric device 1.
is the foundation bolt, and 6 is the bit. The installation work for an electrical device having such a configuration is performed in the following order: first, the electrical device 1 is installed at a predetermined position, then the elephant 4 is attached, and then electrical connections are made. As shown in detail in FIG. 2, the elephant main body 4a is formed into a rectangular tube shape bent at right angles at the middle portion, and has flanges 4b and 4c provided at both ends.
and a flange 4d provided on the side wall of the elephant main body 4a, and an opening formed in the flange 4d is closed by a cover 4g. The elephant main body 4a is fixed in a predetermined position by a foundation bolt 5 passing through a mounting hole 4f formed in a flange 4c formed at one end, and the other end of the elephant main body 4a is fixed using the flange 4b. This is done by connecting it to the electrical equipment 1 side. Further, the cable 3 is drawn into the elephant main body 4a using the opening opened in the flange 4d by removing the cover 4g, connected to the electrical equipment 1 side with the bushing 2, and fixed to a predetermined position with the cable support 4e. held in position. After these operations are completed, flange 4
Cover 4g is attached to d.

In such a conventional elephant 4, when performing relocation work such as replacing the electrical equipment 1 with a spare machine, the bushing 2 attached to the electrical equipment 1 is
is inserted into the horizontal part of the elephant main body 4a, it is impossible to relocate it simply by separating the flange 4b from the electrical equipment 1, and it is necessary to pull out the foundation bolts 5 and remove the entire elephant main body 4a. However, the disadvantage was that it required an increase in man-hours and an extension of the construction period.

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional method.The Elephant main body can be divided into two parts, a vertical part and a horizontal part. The purpose is to provide an elephant that can be relocated.

An embodiment of this invention will be described below with reference to the drawings. In Figure 3, 1 is an electric device, 2 is a bushing, 3 is a cable, 4 is an elephant body, and 5
is the foundation bolt and 6 is the bit. This configuration is
Except for the structure of the elephant body, it is the same as that shown in FIG. 1, so corresponding parts are designated by the same reference numerals and their explanation will be omitted.

As shown in detail in FIG. 4, the elephant body 4 has a horizontal portion 4a having a flange 4b at one end.
and a vertical portion 4 which also has a flange 4c at one end.
a', and these horizontal parts 4a and vertical parts 4
At the other end of a', flanges 4h and 4i are provided, respectively, which extend along planes that are inclined away from the electrical equipment 1 as they go upward. When these flanges 4h and 4i are connected to each other in a predetermined relationship, the main bodies 4a and 4a' are
The same middle part as shown in FIG. 1 is formed into a square tube shape bent at right angles, but flanges 4h and 4
If i are separated from each other, the horizontal part 4a becomes the vertical part 4
It can be removed from a′. Further, a bushing 2 attached to the electrical device 1 is housed in the horizontal portion 4a.

In addition, cable support 4e foundation bolt mounting hole 4f
The cover 4g is the same as that shown in FIG.

The elephant constructed in this way can be divided into two parts by removing the bolts connecting the flanges 4h and 4i and disconnecting the bushing 2 and cable 3, leaving the vertical part 4a' fixed. , the electric device 1 and the horizontal portion 4a fixed thereto can be moved upward or sideways together with the bushing 2. Therefore, the electrical equipment 1 can be easily installed by attaching the horizontal part 4a to the spare electrical equipment 1, placing it in a predetermined position, and connecting the horizontal part 4a and the vertical part 4a' again with the flanges 4h and 4i. It is possible to make an exchange.

Furthermore, even when newly installing the electrical equipment 1, it can be done after the vertical portion 4a' of the elephant main body 4 has been installed in advance, so that workability is significantly improved.

In addition, when relocating, please remove the bushing 2 and cable 3.
As in the conventional case, the cable side bracket (not shown) fixed to the cable support 4e is removed by removing the cover 4g.

Further, in the above embodiment, the horizontal part 4a and the vertical part 4
Although the case is shown in which a rectangular cylinder is used as a', it goes without saying that a cylinder of any other shape such as a circle can be used.

As described above, according to this invention, the Elephant main body is divided into two parts, and these two parts are removably connected with flanges, making it easy to install electrical equipment and replace with spare parts. can be easily carried out, and the efficiency of this work can be greatly improved.
