Abstract

(57) [Abstract] [Purpose] To make it easier to insert the lower part of the transformer into the bottom plate of the transformer tank and to weld the steady rest. [Structure] A bottom plate 4 of a transformer tank 1 is welded to a bottom plate 4 of a frame-like combination of belt-like plates on the outside of the plate 3 and a lower clamp 5 of a transformer contents 2 is inserted to transform the plate. Fix the container 1 and the transformer contents 2. The steady rest 3 has a top portion bent outward and a side extending outside the frame to reinforce the bottom plate.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transformer tank.

[0002]

[Prior Art]

 In the conventional transformer in which the contents of the transformer are mounted in the transformer tank, the steady rest 3 provided on the bottom plate 4 is inserted into the fixing hole 8 formed in the lower clamp 5 as shown in FIG. And the transformer contents 2 are fixed so as not to move. The upper clamp 6 and the transformer tank 1 are fixed to the upper part by bolts. The steady rest 3 is welded to the bottom plate 4, and the welded portion 7 is inside the steady rest 3.

[0003]

[Problems to be solved by the device]

 When mounting the transformer contents 2 in the transformer tank 1, it is difficult to align the bottom plate 4 because the steady rest 3 is not visible from the outside. Further, when the steady rest 3 is welded to the bottom plate 4 of the transformer tank 1, since the fixing hole 8 of the lower clamp 5 contacts the outside of the steady rest 3, the inside of the steady rest 3 is welded. Was difficult. In addition, there is a problem that the bottom plate 4 needs to be thick in order to have a strength capable of withstanding the weight of the transformer contents 2. Therefore, the present invention makes it easy to mount the transformer contents 2 in the transformer tank 1 and facilitates welding of the steady rest 3 and the bottom plate 4.

[0004]

[Means for Solving the Problems]

 According to the first aspect of the invention, a frame body made of a strip plate is welded to the bottom plate as a steady rest for fixing the contents of the transformer to the transformer tank.

According to a second aspect of the invention, in the first aspect of the invention, the sides of the steady rest are extended to the outside of the frame.

According to a third aspect of the invention, in the device of the first or second aspect, the upper portion of the steady rest is bent outward.

[0007]

[Action]

 In the transformer tank according to the first aspect of the present invention, the steady rest can be easily welded to the bottom plate.

In the transformer tank according to the second aspect of the present invention, the bottom plate is reinforced by extending the side of the steady rest outside the frame. Therefore, the thickness of the bottom plate can be reduced, and the weight of the transformer can be reduced.

In the transformer tank according to the third aspect of the invention, the upper portion of the steady rest is bent outward so that the transformer contents can be easily attached to the transformer tank.

[0010]

【Example】

 Fig. 1 shows an example of a transformer in which the contents of the transformer are installed in a transformer tank. A lower clamp 5 is inserted into a steady rest 3 of a frame body composed of a combination of strip-shaped plates provided on a bottom plate 4, and the transformer tank 1 and the transformer contents 2 are fixed so as not to move. As for the upper fixing method, the upper clamp 6 and the transformer tank 1 are fixed by bolts as in the conventional case. Note that the steady rest 3 has a configuration in which the upper portion is bent outward and the sides extend outside the frame. The welded portion between the bottom plate 4 and the steady rest 3 is outside the steady rest 3.

[0011]

[Effect of the device]

 According to the invention of claim 1, since the transformer contents are mounted inside the steady rest frame body, that is, inside, the welded portion is located outside the steady rest, so that workability is improved compared to the conventional welding method. Is improved.

According to the invention of claim 2, since the side plate is extended to the outside of the frame, the strength of the bottom plate can be increased, so that the bottom plate can be made thin and the transformer tank can be made inexpensive. You can

According to the third aspect of the present invention, the upper portion of the steady rest is bent outward, so that the workability is improved when the transformer contents are inserted into the transformer tank.
