Abstract

PURPOSE: To reduce the housing time of the content of a transformer in the tank of the transformer and prevent the content from colliding with and being damaged by the tank at the time of housing the content in the tank and, at the same time, to reduce the size of the tank. CONSTITUTION: Rails 7 are provided on the internal side face of a tank 1 and guides 8 which can be put on the rails 7 are provided on the surfaces of upper clamps 5 and lower clamps 6 for the content 2 of a transformer are provided. The content 2 of the transformer is housed in the tank 1 by putting the guides 8 on the rails 7 and sliding the guides 8 on the rails 7. The guides 8 of the upper clamps 5 and the guides 8 are internally threaded so that they can be fixed to the tails 7 on the tank 1 side with bolts 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transformer, and more particularly to the structure of a transformer tank and a transformer contents.

[0002]

2. Description of the Related Art FIG. 2 (a) shows the state of contents stored in a conventional transformer tank. Attach the wire rope 4 to the hanging ear 3 provided on the upper clamp 5 of the transformer contents 2, lift the transformer contents 2 with a crane, and displace the transformer contents 2 such as rotation and lateral shaking provided in the tank 1. The lower steady rest 11 for prevention fits the steady rest of the lower clamp 6, and the upper steady rest 1 provided in the upper clamp 5
The contents of the transformer 2 are slowly lowered to the bottom of the tank 1 and stored while visually confirming that 0 matches the steady rest of the tank 1. Fig. 2 (b) shows the contents 2 of the transformer.
2 is a plan view showing a state in which the tank is stored in the tank 1.
By fixing with, the contents of the transformer are prevented from rotating, swaying, and shifting in the vertical direction.

[0003]

However, in the above-described conventional structure, when the transformer contents 2 are lowered into the tank 1 from the state where the transformer contents 2 are lifted by the wire rope 4,
Transformer contents 2 shake and collide with tank 1, resulting in transformer contents 2
May be damaged. In addition, since the positioning of the lower steady rest 11 and the upper steady rest 10 for preventing the displacement of the transformer contents 2 and the storage of the transformer contents 2 are visually confirmed, the transformer contents 2 are extended to the bottom of the tank 1. It takes time to store. The size of the tank 1 must also be set in consideration of the fluctuation caused by lifting the transformer contents 2. Therefore, in the present invention, when the transformer contents 2 are stored in the tank 1, the shaking is prevented, and the transformer contents 2 are not damaged.
The objective is to provide a structure that can be reliably stored in a short time and to reduce the tank size.

[0004]

In order to achieve the above-mentioned object, the present invention provides a rail on the inner surface of the tank facing from the upper part to the lower part, and a guide which fits on the rail is provided on the inner side while sliding. It is characterized by having a structure for storing. Further, as a prevention of the displacement of the contents, a screw hole is provided in the guide on the upper side of the contents, and the guide is fixed to the inner rail of the tank.

[0005]

With this structure, when the contents are stored in the tank, if the rails on the inner side of the tank are aligned with the guides on the contents side, the guides will slide naturally along the rails. Unlike the case of being guided and visually positioned and stored, the contents do not collide with the tank. Further, since the guide serves as the lower steady, the lower steady is not necessary, and the upper steady of the inner side guide and the rail are provided with screw holes and fixed to the inner rail of the tank to serve as the upper steady. Furthermore, since the above structure prevents the fluctuation, it is possible to reduce the margin of the tank size in consideration of the fluctuation.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of the implementation of the present invention. FIG.
In (a), the contents of the transformer are first stored in the transformer tank in the same manner as the conventional method.
To lift. Then, on the inner surface of the tank 1, a rail 7 having a rectangular cross section made of a metal material and a guide 8 having a shape fitting with the rail 7 made of the metal material on the surface of the lower clamp 6 of the transformer contents 2 are fitted. Lower the contents of the transformer 2 into the tank 1. When a guide 8 having a shape fitting with the rail 7 made of a metal material on the surface of the upper clamp 5 of the transformer contents 2 approaches the rail 7 on the inner surface of the tank 1,
With the rail 7 and the guide 8 put together, the transformer contents 2 are lowered to the bottom of the tank 1 and housed. further,
The structure is such that the screw holes of the guide 8 of the upper clamp 5 of the transformer contents 2 are aligned with the screw holes of the rail 7, and the rail 7 and the guide 8 on the inner surface of the tank 1 are fixed with bolts 9.

[0007]

As described above, according to the present invention, the following effects can be obtained in storing the contents in the transformer tank. (1) Conventionally, it took time to store the contents of the transformer while visually aligning the contents of the transformer with the position of the lower steady rest and the position of the upper steady rest, but in the present invention, the lower steady rest is unnecessary, and the upper steady rest Since it can also be used as a guide, visual positioning is not required to store the contents in the tank, and the storage is structured by sliding the rail on the inner surface of the tank and the guide on the content side, shortening the storage time Can be achieved. (2) When storing the contents of a transformer in the tank, the rails on the inner surface of the tank and the guides on the contents side guide it to the bottom of the tank. , The contents will not shake, and damage to the contents due to collision with the tank surface can be prevented. (3) Since the structure of the above (2) can prevent the fluctuation of the contents, it is possible to reduce the margin of the tank size in consideration of the fluctuation and reduce the size of the tank.
