Description

[Detailed Description of the Invention] The present invention relates to an electrical equipment tank.
For example, in ground-mounted capacitor equipment in which multiple large capacitors are placed close to each other as a group, they are placed in a temporary position using a retcher, roller puller, etc., and then finely adjusted using a slide jack. After that, the official installation will be carried out. Such fine adjustments need to be made in the X and Y axis directions, but
The capacitor tank is provided with only two jack stands on two opposing sides, and on each side.
Hereinafter, FIG. 1 is a drawing for explaining the arrangement and installation of a plurality of conventional large capacitors, and FIG. 2 shows a slide jack used for movement.

A slide jack S has a fixed base 1 having a length L, a sliding support base 2, and a shaft fixed on both sides of the fixed base 1,
It consists of a feed shaft 3 (not shown) that is screwed into the lower surface of the sliding support 2, and on the sliding support 2 there is a jack consisting of a load receiver 4 that moves up and down by hydraulic pressure and a hydraulic cylinder 5. 6 is fixed. Jyatsuki 6
By rotating the feed shaft 3, the fixed base 1
slide on top.

Reference numerals 11, 12, and 13 each indicate a capacitor tank, and the figure shows the state after installation.

Each of the capacitor tanks 11, 12, and 13 has two jack stands 14 on two opposing side walls.

Before the capacitor tank is set in such an installation position, the movement direction of the slide jack S is set parallel to the X-axis direction under the four jack stands 14 of the capacitor tank, and the tank is pushed up by the jack 6. The feed shaft 3 of each slide jack S is rotated in a predetermined direction, and the capacitor tank moves in the X-axis direction.
If a slide jack S is installed in the Y-axis direction under the tank and the tank is pushed up by the jack 6, the feed shaft 3 is rotated, and then, for example, a capacitor tank 1
2. In this case, however, there is no problem if the predetermined installation interval G between the two tanks is greater than the length L of the fixed base 1 of the slide jack S. However, if the length L of the fixed base 1 is greater than the installation interval G, it becomes impossible to perform work within the above-mentioned interval due to the mechanism for rotating the feed shaft 3. However, the slide jack is a tool that can be moved easily and reliably, and this invention improves the support part that is provided on the side wall of the electric equipment tank and supports the load of the electric equipment so that such a commercially available slide jack can be used even with an interval narrower than the length of the slide jack as described above. Figure 3 shows a top view of an example in which multiple capacitor tanks according to this invention are arranged. In the figure, each capacitor tank 21, 2
2, 23, the side wall 25 has a lower part
A support portion 26 is formed to support the load of the capacitor. The support portion 26 is, for example, a capacitor tank 21.
At least two of the support members are provided on each side wall 25, and more are provided depending on the load support. In the figure, eight support members are provided on the four side walls 25. A jack support base, which will be described later, is fixedly supported on the support member 26 as is, or is removably attached thereto.

If the support parts 26 are provided at eight locations in this way, for example, the capacitor tank 23 can be moved in the X-axis direction as described above, and the movement in the Y-axis direction can be moved even if it is predetermined. Even if the gap G′ between the capacitor tanks is smaller than the length L of the slide jack S, the capacitor tank 2
2 and the side wall 25 where the capacitor tank 23 faces each other.
side wall perpendicular to , that is, side wall 2 parallel to the Y axis
Slide jacks S are installed in the direction parallel to the Y-axis under the jack supports 27 supported by the four support parts 26 at 5, and the tank is pushed up with jacks 6 and the feed shaft 3 is rotated. For example, the capacitor 23 can be moved to a predetermined distance G'. FIG. 4A shows the jack support 2 on the support part 26.
7 is an example in which it is fixed and attached. The jack support base 27 connects the rib 28 on the side wall 25 to the support part 26.
It is fixed as The jack support stand 27 consists of a bottom plate 29 that receives pushing up force and a U-shaped side plate 30 that reinforces the bottom plate 29.
0 and the rib 28 are attached by welding.

FIG. 4B shows an example in which a jack support part 27' is attached to the support part 26 as described later. The figure is a view of the support base 27' attached to the support part 26, viewed from the side. A reinforcing plate 32 is welded across both edges of an I-shaped rib 31 protruding from the side wall 25, and a hole 33 is drilled through the two reinforcing plates 32 and the rib 31 on the lower end side to form a supporting portion 26. is formed. On the other hand, a stopper rod 3 is placed between the non-right-angled tops of the two right-angled triangular side plates 34.
5, and a bottom plate 36 was fixed to the lower side of the right-angled top by welding or the like, and this assembled jack support stand 27' was placed over the reinforcing plate 32, and a hole was made at the top of the remaining triangular side plate 34. Hole and the reinforcement plate 3
2 and the hole 33 passing through the rib 31 and fasten with the insertion pin 24, the jack support 27' is held against the upward force from the direction of the bottom plate 36, with the retaining rod 35 in contact with the rib 31. will be formed. This jack support base 27' is attached to the insertion pin 2.
4, it can be removed and attached freely.

If the jack support stand 27' shown in Fig. 4B is used, this jack support stand can be finally removed on the surface where the capacitor tanks face each other and are close to each other, so it is very convenient when further narrowing the gap. .

The capacitor tank has been explained above, but it is clear that the present invention can also be applied to other oil-filled electrical equipment such as transformers and series reactors, and by improving the tanks of these electrical equipment, the installation work time can be shortened.
