Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a voltage transformation system and a transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In the prior art, due to the large size of the transformer, the transformer and the oil storage cabinet are made into separate types, which can be easily transported. Specifically, holes are opened on the inner surface of the transformer cover to weld fixing bolts, which can ensure the strength of the welding (due to the large mass of the oil storage cabinet, the fixing bolts directly welded on the outer surface of the cover are not strong enough and are easy to break). The disadvantage is that there is a risk of oil leakage from the cover. If the inner surface of the cover is not welded well, it will cause oil leakage from the cover. Utility Model Content

[0003] The purpose of the utility model is to provide a voltage conversion system and a transformer to solve the above problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] In a first aspect, the utility model provides a transformer, including a transformer body, an oil storage cabinet and a fixing structure;

[0006] The transformer body has a box cover for connecting to the oil conservator, and the oil conservator is provided with cabinet feet for connecting to the box cover, and the cabinet feet are connected to the box cover through a fixed structure;

[0007] The fixing structure includes a base and a fixing member. The base has two opposite outer surfaces, one of which is connected to the box cover, and the other is connected to the cabinet foot through the fixing member. Accordingly, the fixing member passes through the cabinet foot and then connects to the base.

[0008] In a possible design, the base has a basic shape and thickness, a connection hole is provided on the top surface of the block structure, and the fixing piece is constructed as a fixing rod detachably arranged on the connection hole.

[0009] In a possible design, the base is made of flat steel or channel steel, and the fixing members are made of fixing bolts. Accordingly, screw holes adapted to the fixing bolts are provided on the flat steel.

[0010] In a possible design, a plurality of cabinet feet are provided, and a plurality of fixing structures are provided and are arranged one-to-one corresponding to the cabinet feet.

[0011] In a possible design, a delivery pipe is provided between the transformer body and the oil conservator.

[0012] In a second aspect, the utility model provides a voltage transformation system, including the transformer.

[0013] Beneficial effects:

[0014] The transformer body and the oil conservator are connected through a fixed structure. The base is fixed on the cover of the transformer body, which can not only be used to connect the oil conservator, but also strengthen the overall strength of the cover. The thickness of the cover can be appropriately reduced, reducing costs. The connection and fixation are achieved through the penetrating fixings, and there is no need to open holes on the cover for welding, which not only avoids the risk of oil leakage, but also reduces the requirements for welding quality, making it more convenient to use and more practical.

[0019] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0020] Example:

[0021] like Figure 1 and Figure 2 As shown, a transformer comprises a transformer body 1, an oil storage cabinet 2 and a fixing structure 3;

[0022] The transformer body 1 has a box cover 4 for connecting to the oil storage cabinet 2. The oil storage cabinet 2 is provided with a cabinet foot 5 for connecting to the box cover 4. The cabinet foot 5 is connected to the box cover 4 through a fixing structure 3.

[0023] The fixing structure 3 includes a base 301 and a fixing member 302 . The base 301 has two opposite outer surfaces, one of which is connected to the box cover 4 , and the other is connected to the cabinet foot 5 through the fixing member 302 . Accordingly, the fixing member 302 passes through the cabinet foot 5 and then connects to the base 301 .

[0024] Since the prior art has the risk of oil leakage, the transformer does not consider the technical solution of opening a hole in the box cover 4 to avoid the potential risk of oil leakage. Specifically, the transformer body 1 and the oil storage cabinet 2 are connected through the fixing structure 3, and the base 301 is fixed on the box cover 4 of the transformer body 1, which can not only be used to connect the oil storage cabinet 2, but also strengthen the overall strength of the box cover 4. The thickness of the box cover 4 can be appropriately reduced, reducing the cost. The cabinet foot 5 is placed on the base 301, and the connection and fixation are achieved through the fixed parts 302. Based on this, there is no need to open holes on the box cover 4 for welding, which not only avoids the risk of oil leakage, but also reduces the requirements for welding quality, making it more convenient to use and more practical.

[0025] It is easy to understand that the oil conservator 2 is provided with a plurality of cabinet feet 5, and correspondingly, the fixing structure 3 is provided with a plurality of cabinet feet 5 and is arranged one-to-one with the cabinet feet 5, that is, each cabinet foot 5 is connected through the fixing structure 3 to ensure the connection between each cabinet foot 5 and the box cover 4, so that the connection between the transformer body 1 and the oil conservator 2 is more stable.

[0026] In this embodiment, the base 301 has a basic shape and thickness, a connection hole is provided on the top surface of the block structure, and the fixing member 302 is configured as a fixing rod detachably provided on the connection hole. Based on the above design scheme, theoretically, the base 301 can be configured in any suitable shape. Considering the convenience of processing, the base 301 is preferably configured as a cube, or the base 301 is selected from any suitable commercially available component. The fixing member 302 is preferably a detachable component such as a bolt or a screw, and the specific type can be determined according to actual use requirements.

[0027] In a possible implementation, the base 301 is made of flat steel or channel steel, and the fixing member 302 is made of fixing bolts. Accordingly, the flat steel is provided with screw holes adapted for the fixing bolts. Based on the above design scheme, the flat steel refers to a steel material with a width of 12-300 mm, a thickness of 3-60 mm, a rectangular cross section and slightly blunt edges. The flat steel can be a finished steel material, which can be cut according to the size of the cabinet foot 5. The channel steel is a long steel strip with a groove-shaped cross section, which can be cut according to the size of the cabinet foot 5, and the cost of using the channel steel is lower than that of the flat steel. The fixing bolts can not only achieve connection and fixation, but also have detachable properties to facilitate subsequent separation.

[0028] In this embodiment, there are a plurality of cabinet feet 5, and a plurality of fixed structures 3 are provided and arranged one-to-one corresponding to the cabinet feet 5. It is easy to understand that the number of cabinet feet 5 of the oil conservator 2 of different types of transformers is different, and the corresponding number of fixed structures 3 can be selected according to the specific number of cabinet feet 5.

[0029] In this embodiment, a delivery pipe is provided between the transformer body 1 and the oil storage cabinet 2. Based on the above design, the oil is delivered through the delivery pipe, providing an energy source for the operation of the transformer body 1. Figure 1 As shown, the conveying pipe is preferably designed as a curved pipe.

[0030] This embodiment introduces a transformer system based on the transformer, and the transformer system includes the transformer. Based on the above design scheme, the transformer system can include any suitable functional module to achieve the corresponding function. Accordingly, the functional module can select any suitable commercially available equipment. The transformer has a wide range of uses and good practicality.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
