Abstract
Description
Technical Field
[0001] The utility model relates to the field of dry-type transformers, and particularly relates to a base of a dry-type transformer. Background Technique
[0002] A dry-type transformer, as a common type of transformer in the power system, has a core working principle similar to that of an oil-immersed transformer, both based on the electromagnetic induction principle to achieve voltage level conversion. However, there are significant differences in their cooling and insulation methods.
[0003] In the design of dry-type transformers, the base part often faces some challenges. Specifically, the base is composed of multiple side bars and transverse frames. Although this structure has its unique features, it brings many inconveniences during the installation process. Installers need to install and fix these components one by one, resulting in a cumbersome and time-consuming installation process, thereby prolonging the project cycle and increasing labor costs.
[0004] In addition, when multiple dry-type transformers need to be spliced and used, the design problem of the base is particularly prominent. Since each component is installed independently, it is difficult to achieve precise alignment, which may lead to uneven gaps between transformers, affecting the overall aesthetics and stability. At the same time, the complex base structure may also affect the overall operation efficiency of the transformer. Especially during the splicing process, if the alignment is improper, it may lead to loose connections, thereby affecting its normal operation.
[0005] The complex base structure brings great difficulties to daily maintenance and repair. When the transformer needs to be replaced or maintained, the entire base may need to be disassembled, which undoubtedly increases the maintenance cost and time cost. There are many deficiencies in the design of the dry-type transformer base, and it needs to be further optimized and improved to improve its installation efficiency, stability, and maintainability. Content of the Utility Model
[0006] The main purpose of the utility model is to provide a base of a dry-type transformer, which can effectively solve the problems put forward in the background technique.
[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0008] A base of a dry-type transformer includes a top frame, a transformer main body, and side frames. The top frame and side frames are distributed at the upper end and side walls of the transformer main body. The transformer main body is fixed to the top frame through bolts, nuts, and anti-slip gaskets.
[0009] A first modular base, a docking base, and a second modular base are sequentially arranged at the lower end of the transformer main body from left to right. Side mounting blocks are provided on the side walls of the first modular base, the docking base, and the second modular base. The side mounting blocks are connected to the side frames through bolts to achieve lateral installation.
[0010] A plurality of transverse bases are provided at the lower ends of the first modular base, the docking base, and the second modular base, and protruding mounting blocks adapted to the modular base and the docking base are provided at the upper ends of the transverse bases. Circular holes on the protruding mounting blocks are aligned with the mounting hole positions opened on the modular base and the docking base, and bolts are inserted into the mounting hole positions to fix the transverse base to the modular base and the docking base;
[0011] The transverse base at the lower end of the docking base is fixed to the transverse base at the lower end of the modular base through fastening screws and fastening nuts, and rapid assembly and splicing of a plurality of transformer bodies are realized through the modular base, the docking base, and the transverse base.
[0012] In a further preferred solution, rubber strips are provided between the first modular base, the second modular base, and the docking base. The first modular base and the second modular base are welded and fixed to the side mounting blocks, and screw holes are provided on the side mounting blocks;
[0013] In a further preferred solution, the protruding mounting blocks are welded to the transverse bases, the cross-section of the protruding mounting blocks is designed in a "U" shape, and rubber gaskets are provided at the contact ends of the protruding mounting blocks with the first modular base, the second modular base, and the docking base;
[0014] In a further preferred solution, protruding mounting blocks are installed at both the inner and outer ends of the first modular base, the second modular base, and the docking base, and the protruding mounting blocks are symmetrically arranged on the transverse bases;
[0015] In a further preferred solution, the transverse bases are perpendicular to the first modular base, the second modular base, and the docking base;
[0016] In a further preferred solution, a plurality of circular holes are provided at both ends of the transverse base. A plurality of fastening screws pass through two transverse bases at the lower end of the docking base, and fastening nuts and anti-slip gaskets are sleeved on the fastening screws to fix the docking base to the modular base.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] In the utility model, the modular design enables each component to be quickly combined together, greatly shortening the assembly time. Each modular base and docking base can be prefabricated and quickly spliced on site, improving the installation efficiency. This design can realize the assembly of a plurality of dry-type transformers. Through the ingenious design of the docking base and the transverse base, a plurality of transformer bodies can be stably connected together, facilitating the construction of a large-scale power system.
[0019] The modular base and the side frame are closely fitted, and the tight fixation by bolts, nuts and anti-slip gaskets ensures the stability of the entire transformer base and avoids vibrations during operation. Embedding rubber strips between the bases can effectively reduce the noise and vibration generated during the operation of the transformer and improve the operation quality of the equipment.
[0020] The vertical design of the transverse base and the modular base not only enhances the stability of the base but also improves its load-bearing capacity. The modular design also makes future maintenance work more convenient. Each module can be disassembled and replaced separately, reducing the maintenance cost. The symmetric design of the protruding mounting blocks and the round hole design at both ends of the transverse base ensure the balance and stability of the entire base structure.

Detailed Implementation Manner
[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.
[0027] As Figure 1 - Figure 4 shown, an innovative design of the dry-type transformer base structure includes three core components: the top frame 1, the transformer main body 2 and the side frame 3. The top frame 1 is stably placed on the top of the transformer main body 2, and the side frame 3 is cleverly surrounded by its side wall. The tight cooperation between the two through bolts, nuts and anti-slip gaskets ensures the stability and safety of the structure.
[0028] At the bottom of the transformer main body 2, we have carefully arranged the first modular base 4, the docking base 6, and the second modular base 5. These three are arranged in sequence from left to right, forming the modular foundation of the base. On the side walls of each modular base, side mounting blocks 7 are cleverly set. These side mounting blocks 7 are tightly connected to the side frame 3 through bolts, thus achieving the lateral stable installation of the base.
[0029] To further enhance the structural stability, we have designed multiple transverse bases 8 at the lower ends of the modular base and the docking base 6. At the upper ends of these transverse bases 8, prominent mounting blocks 9 that are perfectly adapted to the modular base and the docking base 6 are specially configured. The round holes on the prominent mounting blocks 9 are precisely aligned with the mounting hole positions 10 on the modular base and the docking base 6. Through the insertion and tightening of bolts, the tight fixation of the transverse base 8 with the modular base and the docking base 6 is achieved.
[0030] The transverse base 8 at the lower end of the docking base 6 is also tightly connected to the transverse base 8 at the lower end of the modular base through the ingenious combination of a fastening screw 11 and a fastening nut 12. This design greatly improves the overall stability of the base and also makes it possible for the rapid assembly and splicing of multiple transformer main bodies 2.
[0031] In addition, we have also cleverly embedded rubber strips between the first modular base 4, the second modular base 5, and the docking base 6 to reduce vibration and noise. At the same time, both the first modular base 4 and the second modular base 5 are tightly connected to the side mounting blocks 7 by welding, ensuring the firmness and reliability of the connection. The screw holes opened on the side mounting blocks 7 facilitate the subsequent bolt installation.
[0032] The design of the prominent mounting blocks 9 is also ingenious. Its cross-section is designed in a "U" shape, which is not only beautiful and generous, but also rubber gaskets are provided at the contact ends with the modular base and the docking base 6, further improving the sealing and stability of the connection. These prominent mounting blocks 9 are symmetrically arranged on the transverse base 8, ensuring the balance and stability of the base structure.
[0033] Finally, the design that the transverse base 8 is perpendicular to the modular base and the docking base 6 not only improves the load-bearing capacity of the base, but also makes the entire base structure more compact and stable. The multiple round holes opened at both ends of the transverse base 8 facilitate the passing through and tightening of the fastening screw 11. Multiple fastening screws 11 pass through the two transverse bases 8 at the lower end of the docking base 6, and through the cooperation of the fastening nut 12 and the anti-slip gasket, the firm fixation of the docking base 6 and the modular base is achieved.
[0034] Assembly process: Ensure that all components (top frame 1, transformer body 2, side frames 3, first modular base 4, docking base 6, second modular base 5, side mounting blocks 7, transverse base 8, protruding mounting blocks 9, fastening screws 11, fastening nuts 12, anti-slip gaskets, etc.) are complete and undamaged.
[0035] Arrange the first modular base 4, docking base 6, and second modular base 5 in order from left to right, ensuring there is enough clearance between them for subsequent installation. Weld the side mounting blocks 7 to the side walls of each modular base, ensuring firm welding and accurate positioning.
[0036] Install the transverse base 8 at the lower ends of the modular base and docking base 6. Ensure that the protruding mounting blocks 9 of the transverse base 8 are aligned with the mounting holes 10 of the modular base and docking base 6. Pass bolts through the round holes of the protruding mounting blocks 9 and the mounting holes 10 on the modular base and docking base 6, and tighten the bolts to firmly fix the transverse base 8 to the modular base and docking base 6. Connect the side frames 3 tightly to the side mounting blocks 7 with bolts and nuts, ensuring that the side frames 3 firmly surround the side walls of the transformer body 2.
[0037] Place the transformer body 2 on the modular base, ensuring it fits tightly with the base. Steadily place the top frame 1 on the top of the transformer body 2 and ensure the top frame 1 is stable through appropriate fixing methods (such as bolts).
[0038] Use the fastening screws 11 and fastening nuts 12 to tightly connect the transverse base 8 at the lower end of the docking base 6 to the transverse base 8 at the lower end of the modular base, ensuring the overall stability of the base. Check whether all bolts and nuts are tightened and make adjustments if necessary.
[0039] Insert rubber strips between the first modular base 4, second modular base 5, and docking base 6 to reduce vibration and noise. Carefully check the stability of the entire base structure, the tightness of the connections, and the integrity of each component. Ensure that all installation steps have been completed and meet the design requirements. The assembly process of the dry-type transformer base is completed. This assembly process fully considers the stability, safety, and maintainability of the structure, ensuring the safe and stable operation of the transformer.
[0040] The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts, and equipment all adopt conventional models in the existing technology, and the circuit connections adopt conventional connection methods in the existing technology, which will not be elaborated here.
[0041] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
