Description

[Detailed Description of the Invention] This invention relates to a stationary induction device, and specifically includes an outer box for storing the device body, a hanging handle for hoisting the device body, and a top surface of the replacement box. This relates to stationary induction equipment, such as transformers, that is equipped with a top plate that closes.

A transformer will be explained below as an example.

Conventionally, this type of transformer is shown in Fig. 1, 8+! There were those shown in Figure 1 and Figure 3. In the figure, / is the main body of the transformer, and a foot plate is attached to the lower part of the main body of the transformer.
The foot plate 2 is provided with a hole 3 as shown in FIG.

G is an outer box that houses the transformer main body L, and the bottom plate G alc of the outer box G is fixed with a clasp 5 as shown in Figure 3, and the clasp S
By passing through the hole 3 of the foot bolt, the transformer body l
The positional relationship between the box and the outer box is regulated. On the top plate of 6#'i, 7 rungs with holes 7 are formed, and the tap changer is mounted so as to be suspended, and it is fixed to the outer box with #10 connections. Ru. A lifting hand // for hoisting the transformer body l is fixed at the upper end of the transformer body l. 1 is a connecting metal fitting for connecting the transformer main body l to the top @A via the hanging handle ll; The end is fixed to the top plate 6 by POL)/fK. lS is hole 7
1A is a connection lead that connects the transformer main body 1 and the tap changer 1, and 17 is an insulating oil sealed inside the outer box q.

Inserting the main body l of the transformer constructed as described above into the outer box q, as shown in Fig. q, places a top plate A on the top of the main body of the transformer and connects it with a connecting fitting 12. Then, attach the tap cutter to the top plate 6, connect it to the main body of the transformer with the connecting lead 16, attach 7 g of rope to the hanger from the hole in the 7 lunge, and lift it up. <<[Insert.

At this time, position 1 = so that the stopper S is engaged with the hole 3 of the leg lock.
Perform the matching. The reason for attaching the top plate A to the transformer body l and inserting it into the outer box II K4A is to connect the tap changer 9 attached to the top plate T and the main body l with the connection lead lI-. This is because it is impossible to do this after inserting it into the outer box.

As mentioned above, after inserting the transformer body into the outer box IK,
In order to correct the height dimension with the outer box q and the positional relationship dimension between the outer box q and the top plate 6, connect the connecting fitting 12 from the hole 7 of the 7 flange g. , Loosen /4' to remove the tori,
Arrange the Ounuki 6 so that it is in the correct position relative to the outer box. At this time, the positional relationship between the hanging handle 11 and the top plate 2 deviates from the original position before insertion of the outer box, so the connection fitting 12 is connected to the position 1)/7. I
After adjusting the position of the through hole (not shown) of II, etc., I added a little salt 9. After attaching the connecting fitting 12, I attached the 7/1 to the flange, and then welded and fixed the top plate and the outer box q using I/O.

Conventional transformers were constructed as described above, so there was no need for connecting fittings, and the main body of the transformer was attached to the outer box.
Bolt after inserting K/? , Loosen /u and connect the connecting fittings /2
You have to remove it and then process the connecting fitting 12 9
Since this method does not require a large number of steps, it requires a large number of man-hours to manufacture, which has the drawback of increasing the number of manufacturing days and costs. Also, with the top &A closed fy on the outer box q, Holt/3. It also had the disadvantage that the electrical reliability of the transformer r and main body l was lowered because abrasion powder of gold and paint generated when attaching and detaching the /4< was dropped. Furthermore, I=Jh between the transformer main body l and the top plate 6 is determined by the holt /3. The space required for attaching and detaching the transformer is larger, which increases the amount of insulating oil sealed in the outer box, increasing costs, and also has the drawback of increasing the size of the transformer. Ta.

This invention eliminates the drawbacks of the conventional ones as described above! i,
It was made to remove the hanger from the upper part of the device, and the hanging handle was passed through the top plate, and a cap was attached to the large plate to cover the hanging handle that protruded beyond the top plate. In particular, the purpose of the present invention is to provide a silent guide slowing device that is easy to manufacture, requires less manufacturing man-hours, is not cheap, and has high quality reliability.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Fig. 3, the difference from the conventional one is that a hole -0 is provided in the top plate 19, the hanging handle 1/ is passed through the hole O, and the part where the hanging handle // protrudes from the top plate /9 is The cap is covered with 2/, and the top plate of the hanging hand//? It is located at the point where one deposit 22 is placed on the lower side of . That is, the hanging hand attached to the upper part of the transformer main body l passes through a hole θ provided in the top plate 19 and projects from the top surface of the top plate 19. Also, the size of the hole O is the hanging hand/
The outer box and top plate should be made larger than the cross section of L. K is designed to absorb dimensional errors between the transformer body and the transformer body. This is fixed to the hanger // with a support, and is positioned slightly lower than the top plate 19.

For covering the part of the hanging hand // that protrudes beyond the top plate 19, one is on the left side of the hanging hand ii, and the other is on the left side of the hanging hand ii.
I! ll is in contact with the right side of the other hanging hand ll, and the top plate 1
9 is fixed with welding bolt 3. Other parts that are the same as those in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted.

Due to the above structure, in order to insert the main body of the transformer into the outer box, as shown in Fig. , and also the L-shaped metal and the T-shaped handle/
Attach it to / so that the top plate /q can be raised. Like this, the main body and top plate of a Ki pressure device? In the combined state, the rope 15 is attached to the hanging hand /1, and the main body / is inserted into the lifting outer box q.

At this time, alignment is performed so that the stopper 5 passes through the hole 3 of the leg λ.゛Also, before removing the rope/g, remove the L-shaped fitting 2q from the hanger //, and after adjusting the dimensions of the top plate/9 to the outer box q, remove the rope/g. This work involves removing the L-shaped metal fittings and removing the top plate. The connection with the hanger +l/ is released, and the hole 20 made in the top plate /9 to allow the hanger /l to pass through is made larger than the hanger //, so the main body of the transformer / is removed. Even when it is aligned with the clasp plate fixed to the bottom plate &a of the box q, the top plate/9 height can be easily finely adjusted to match the outer box height. After completing the alignment of the top plate 19 to the outer box q in this way, place one cap λ/ on the left side of the hanging handle l/.
The other one is tgINed to the top plate 19 by welding 3 so as to contact the left side surface of the hanging handle l/.

As described above, according to the present invention, the hanger 1/ attached to the upper part of the main body l of the transformer is passed through the top plate 19, and the cap collar is attached to cover the part protruding from the top plate 9. Since the main body of the transformer is fixed to the top plate 19 by contacting the hanger //, the main body of the transformer is firmly held on the top plate 19 via the hanger // and the cap 21 against the movement during transportation. This makes it possible to omit the conventional connecting metal fittings, which reduces costs.In addition, the connecting metal fittings can be connected to the hanger and the top plate with bolts, and the dimensions of the transformer can be adjusted after inserting the contents of the transformer into the outer box. This eliminates the process of removing and reprocessing the connecting metal fittings and then reattaching them to the top plate and hanger, which shortens the production time and prevents metal and paint particles from falling. Therefore, it has the advantage of improving the electrical reliability of the transformer.

Furthermore, since there is no need to tighten bolts or attach ropes inside the top plate, it is possible to reduce the distance between the IMj between the top plate and the transformer body to the minimum necessary, which was previously required for this purpose. This makes it possible to save on insulating oil,
It also has the advantage that the transformer can be made into a small shaft, and its moving bed is very large.
