Description

An installation structure of an amorphous alloy transformer

technical field

The invention relates to a transformer, in particular to an installation structure of an amorphous alloy transformer.

Background technique

There are two installation structures for the traditional amorphous alloy transformer body after it enters the oil tank. One is that the body is positioned by several positioning devices at the bottom of the oil tank and is not fixed. Once the coil suddenly short-circuits in this structure, the body will jump with the vibration of the coil in the fuel tank, and the amorphous alloy iron core in the body will inevitably be impacted to generate additional stress, which will produce iron core fragments , the no-load loss will also increase. Another kind of structure is that the clip connected on the body of the device is connected with the tank cover of the fuel tank by a screw rod, and the height of the body of the regulator entering the fuel tank is adjusted by the threads. This structure fixes the body by welding four screws under the cover and the rigid connection of the body. Although the body can be fixed to avoid vibration, but because the thread needs to be adjusted to keep the cover level, the assembly will be time-consuming and the case The accuracy with which the lid remains level is also not high.

Contents of the invention

The purpose of the present invention is to provide a mounting structure for an amorphous alloy transformer, which can reduce the corresponding vibration of the body due to the electrodynamic force generated by the coil when the transformer suddenly short-circuits, and can effectively avoid the vibration of the transformer due to vibration. The additional stresses lead to increased no-load losses and the generation of core fragments.

The technical solution for achieving the above purpose is: an installation structure of an amorphous alloy transformer, including an oil tank of the amorphous alloy transformer and a body of an amorphous alloy transformer placed in the oil tank and including an upper clamp, the oil tank includes cover and case, wherein,

Several fixing plates are uniformly connected to the lower end surface of the box cover;

A number of right-angled bridge plates corresponding to the fixed plate are fixed on the top surface of the upper clamp;

The lower end surface of each of the fixing plates is pressed against the top surface of the upper clip of the body through a first buffer pad, and the side of each of the fixing plates is in contact with the vertical portion of the corresponding bridge plate. A second buffer pad is arranged between them and connected to the bridge plate through a connecting piece.

In the installation structure of the above-mentioned amorphous alloy transformer, the body is placed in the oil tank through a positioning mechanism provided at the bottom of the box.

In the installation structure of the amorphous alloy transformer mentioned above, the first buffer pad and the second buffer pad are an L-shaped integral structure.

The technical scheme of the installation structure of the amorphous alloy transformer provided by the present invention adopts a high-strength fixing plate under the tank cover of the fuel tank to press the upper clip of the device body, and a rubber buffer pad is arranged between the fixing plate and the upper clip. The method can not only adjust the dimensional tolerance produced during the processing and assembly of the fuel tank, but also reduce the corresponding vibration of the transformer body due to the electric force generated by the coil when the transformer suddenly short-circuits through the vibration damping effect of the cushion, and can effectively avoid The additional stress of amorphous alloy transformers due to vibration leads to increased no-load losses and generation of core fragments.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to Fig. 1, the mounting structure of the amorphous alloy transformer of the present invention includes the oil tank of the amorphous alloy transformer and the body of the amorphous alloy transformer, wherein,

The fuel tank includes a tank cover 11 and a box body 12, and the lower end surface of the tank cover 11 is evenly connected with several fixing plates 3;

The amorphous alloy transformer is placed in the oil tank through a positioning mechanism arranged at the bottom of the box body 11;

The body includes an upper clip 5 at the top, and a number of right-angled bridge plates 2 corresponding to the fixed plate 3 are fixed on the top surface of the upper clip 5;

The lower end surface of each fixed plate 3 is pressed against the top surface of the upper clip 5 of the body by a first buffer pad 4, and the side of each fixed plate 3 is arranged between the vertical part of the corresponding bridge plate 2 A second buffer pad 1 is connected to the bridge plate 2 through a connecting piece 6 .

During installation, the first buffer pad 4 is first fixed to the fixing plate 2 on the tank cover 11 and fixed on the top surface of the upper clip 5 by screws 40, and then the body is put into the fuel tank.

Both the first buffer pad 4 and the second buffer pad 1 are made of insulating rubber material and can be made into an L-shaped integral structure.

The installation structure of the amorphous alloy transformer of the present invention is positioned horizontally by the fixed plate 3 connected on the case cover 11 and the bridge plate 2 connected on the upper clamp 5, and the second buffer pad 1 is arranged in the middle to buffer; The fixed plate 3 connected to the tank cover is positioned with the upper clamp 5 on the body, the fixed plate 3 is directly pressed on the upper clamp 5 of the body, the body is tightly pressed into the fuel tank, and the fixed plate 3 The first buffer pad 4 is set between the lower end surface of the upper clamp 5 and the top surface of the upper clamp 5, so that when the transformer suddenly short-circuits, the corresponding vibration of the body due to the electrodynamic force generated by the coil can be reduced, and the amorphous body can be effectively avoided. The extra stress of alloy iron core transformers due to vibration leads to increased no-load loss and generation of iron core fragments. At the same time, it also reduces the assembly time of workers, greatly improves the batch production speed of the same batch of workpieces, and improves work efficiency.
