[0010] Furthermore, the multiple supporting beams include a transformer middle beam disposed between the inner beam of the transformer and the outer beam of the second transformer, with both ends of the transformer middle beam connected to the main beam of the first transformer and the main beam of the second transformer, respectively.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] According to an embodiment of this utility model, a transformer base is provided; please refer to [link / reference]. Figures 1 to 5 The transformer base includes: a transformer main beam, comprising a first transformer main beam 1 and a second transformer main beam 2 arranged opposite to each other; a transformer outer beam, comprising a first transformer outer beam 3 and a second transformer outer beam 4 arranged opposite to each other; a support beam, comprising multiple support beams for supporting electrical components inside the transformer; and a first connector 5, comprising a first connecting plate 51 and a second connecting plate 52 connected to each other, the extension directions of the first connecting plate 51 and the second connecting plate 52 being perpendicular to each other, and both the first connecting plate 51 and the second connecting plate 52 having multiple connecting holes for accommodating fasteners; wherein, the first transformer main beam 1, the first transformer outer beam 3, the second transformer main beam 2, and the second transformer outer beam 4 are connected end to end by the first connector 5 to form the transformer base body, the transformer base body containing multiple support beams, and the multiple support beams being detachably connected to the transformer base body by the first connector 5.

[0028] By using the first connector 5, the connecting hole on the first connector 5 can accommodate fasteners. The fasteners are passed through the connecting hole on the first connector 5 and the connecting hole on the beam body respectively, and then the fasteners are tightened with nuts to complete the assembly of the two beam bodies. This allows the beam bodies to be connected and disassembled quickly and conveniently, improving the flexibility and efficiency of the assembly. At the same time, the first connector 5 has a certain degree of versatility, which improves the utilization rate of the connectors.

[0029] By employing a first connector 5 between the main body of the transformer base and each of the multiple supporting beams, the first connector 5 can be connected to two adjacent beams respectively by screws. The two adjacent beams can be detachably connected through the first connector 5, avoiding the use of welding to fix the first connector 5 to the beams or to assemble and connect the two adjacent beams. The entire assembly process of the transformer base does not require welding, eliminating the need for welders, reducing the requirements for the assembly process, and reducing labor and time costs. In subsequent use, if maintenance, repair, or replacement of parts is required for the transformer base, disassembly and replacement can be carried out quickly, reducing maintenance time and costs, and solving the technical problem of low assembly efficiency of transformer bases in related technologies.

[0030] In the transformer base of this embodiment, see Figure 1 The system includes multiple supporting beams: a lower switch beam 61, which is spaced apart from the outer beam 3 of the first transformer, with both ends connected to the main beam 1 of the first transformer and the main beam 2 of the second transformer, respectively; and an inner transformer beam 62, which is positioned between the lower switch beam 61 and the outer transformer beam, with both ends connected to the main beam 1 of the first transformer and the main beam 2 of the second transformer, respectively. By providing the lower switch beam 61 and the inner transformer beam 62, the system further supports the transformer base within its main body, increasing the structural strength of the transformer base.

[0031] In the transformer base of this embodiment, see Figure 1 A middle beam assembly 63 is provided between the outer beam 3 of the first transformer and the lower beam 61 of the switch, and between the lower beam 61 of the switch and the inner beam 62 of the transformer. The middle beam assembly 63 includes multiple middle beams, and the extension direction of the multiple middle beams is parallel to that of the main beam 1 of the first transformer or the main beam 2 of the second transformer. By providing the middle beam assembly 63, more electrical components can be supported.

[0032] In the transformer base of this embodiment, see Figure 1The central beam assembly 63 includes, arranged sequentially along the direction away from the main beam 1 of the first transformer: a low-voltage central beam 631, on which a low-voltage cabinet is supported; a partition central beam 632; and a high-voltage central beam 633, on which a high-voltage cabinet is supported. This divides the transformer interior into a high-voltage cabinet side and a low-voltage cabinet side, respectively supporting the high-voltage and low-voltage cabinets.

[0033] It is understandable that the transformer is internally divided into a high-voltage cabinet side and a low-voltage cabinet side. The first transformer main beam 1 is close to the low-voltage cabinet side, so the first transformer main beam 1 is the low-voltage side beam. The second transformer main beam 2 is close to the high-voltage cabinet side, so the second transformer main beam 2 is the high-voltage side beam.

[0034] Specifically, a low-voltage intermediate beam 631, a partition intermediate beam 632, and a high-voltage intermediate beam 633 are installed between the outer beam 3 of the first transformer and the lower beam 61 of the switch, and between the lower beam 61 of the switch and the inner beam 62 of the transformer.

[0035] In the transformer base of this embodiment, see Figure 1 The system includes multiple supporting beams, including a transformer middle beam 64 positioned between the inner transformer beam 62 and the outer transformer beam 4. The two ends of the transformer middle beam 64 are connected to the first transformer main beam 1 and the second transformer main beam 2, respectively. By incorporating the transformer middle beam 64, the support strength of the base is further increased, allowing for the placement of heavier cabinets in this area.

[0036] In the transformer base of this embodiment, see Figure 1 Short beam assemblies 65 are provided between the inner beam 62 and the middle beam 64 of the transformer, and between the middle beam 64 and the outer beam 4 of the second transformer. Each short beam assembly 65 includes multiple short beams, and the extension direction of each short beam is parallel to either the first main beam 1 or the second main beam 2 of the transformer. This increases the contact area with electrical components and further increases the support strength of the base.

[0037] In the transformer base of this embodiment, see Figure 1 The transformer base includes a plate assembly, which comprises multiple plates 7. Each plate 7 is installed within a placement groove formed by multiple supporting beams. This placement groove, formed by the supporting beams and with the plate 7 installed within it, serves to prevent dust accumulation inside the transformer.

[0038] Preferably, the mounting plate 7 is located on the side of the placement groove closest to the ground. The installation height of the mounting plate 7 in the placement groove can also be adjusted according to the layout of the electrical components.

[0039] In the transformer base of this embodiment, see Figure 4The supporting beam includes: a main beam body, which includes a first mounting plate 611, a second mounting plate 612, and a third mounting plate 613 connected end to end in sequence, with the second mounting plate 612 perpendicular to the first mounting plate 611 and the third mounting plate 613 respectively; and a fourth mounting plate 614 and a fifth mounting plate 615 spaced apart, with the extension directions of the fourth mounting plate 614 and the fifth mounting plate 615 parallel to the second mounting plate 612 respectively. The fourth mounting plate 614 is connected to the end of the first mounting plate 611 away from the second mounting plate 612, and the fifth mounting plate 615 is connected to the end of the third mounting plate 613 away from the second mounting plate 612.

[0040] Specifically, the first mounting plate 611, the second mounting plate 612, the third mounting plate 613, the fourth mounting plate 614, and the fifth mounting plate 615 on the supporting beam are all formed by bending steel plates. In contrast, traditional bases generally use channel steel as the beam. Compared with traditional bases, using steel plates to form the beam can save raw material costs and reduce the overall thickness of the transformer base.

[0041] In some embodiments, not only do the multiple supporting beams adopt the bending structure described above, but the first transformer main beam 1, the first transformer outer beam 3, the second transformer main beam 2, and the second transformer outer beam 4 can also be made using the bending structure described above.

[0042] In the transformer base of this embodiment, see Figure 4 The paving board 7 includes a paving board body 71 and baffles 72 connected to each other. The extension direction of the baffles 72 is perpendicular to the paving board body 71. There are multiple baffles 72, which are spaced apart circumferentially along the paving board body 71. A first through hole 721 is formed on the baffle 72, and a second through hole 616 is formed on the first mounting plate 611 and / or the fifth mounting plate 615. The first through hole 721 and the second through hole 616 are connected by fasteners. In this way, by setting the baffles 72 and the first through hole 721, the installation of the paving board 7 can be easily completed.

[0043] In some embodiments, the installation height of the paving plate 7 can be adjusted according to actual needs. For example, a second through hole 616 can be opened in the fourth mounting plate 614 to connect the paving plate 7 to the fourth mounting plate 614.

[0044] In some embodiments, the first through hole 721 is an elongated hole, which facilitates the positioning and installation of the finished paving 7.

[0045] In the transformer base of this embodiment, see Figure 5The first connecting member 5 includes a support plate 53, which includes a first connecting edge connected to the first connecting plate 51 and a second connecting edge connected to the second connecting plate 52. The extending directions of the first connecting edge and the second connecting edge are perpendicular to each other. By providing the support plate 53, the structural strength of the support plate 53 is increased.

[0046] In some embodiments, the transformer base includes a low-voltage cabinet U-plate 81 for supporting the low-voltage cabinet body, and the two ends of the low-voltage cabinet U-plate 81 are respectively connected to the first transformer main beam 1 and the low-voltage intermediate beam 631.

[0047] In some embodiments, the transformer base includes a low-voltage cable support assembly 82 for supporting low-voltage cables. The low-voltage cable support assembly 82 includes a low-voltage cable beam 821 and a low-voltage cable clamp 822 mounted on the low-voltage cable beam 821. The two ends of the low-voltage cable beam 821 are respectively connected to two low-voltage cabinet U-plates 81. A low-voltage cabinet cable outlet plate 823 for cable outlet is installed on the low-voltage cabinet plate located below the low-voltage cable support assembly 82.

[0048] In some embodiments, the transformer base includes a manhole 83 mounted on a lowering deck for workers to pass through.

[0049] In some embodiments, the transformer base includes four lifting shafts 84, which are retractable and disposed at the four corners of the transformer base. The lifting shafts 84 are four in number. When the transformer is being lifted, the lifting shafts 84 are pulled out and after use, they are pushed back into the base.

[0050] In some embodiments, the first transformer main beam 1 and the second transformer main beam 2 or the first transformer outer beam 3 and the second transformer outer beam 4 are provided with pull-out holes for the hoisting shaft 84 to pass through.

[0051] In some embodiments, the transformer base includes a transformer plate 85 for mounting transformers, the transformer plate 85 being detachably mounted on the partition beam 632 and the high-voltage beam 633.

[0052] In some embodiments, the transformer base also includes a high-voltage cable support assembly plate 86 disposed at the high-voltage cabinet for supporting high-voltage cables.

[0053] In some embodiments, the transformer base includes a grounding plate 87 for supporting a grounding wire. Two grounding plates 87 are included and are mounted on the first transformer main beam 1 and the second transformer main beam 2.

[0054] In some embodiments, the transformer base includes a surge arrester base plate 88 for mounting surge arresters, with both ends of the surge arrester base plate 88 connected to a partition beam 632 and a high-voltage beam 633, respectively.
