Description

Technical Field

[0001] This invention relates to transformer cabinets, and more specifically to a plate for assembling into a transformer cabinet. Background Technology

[0002] A transformer is a static electrical device that converts a given alternating voltage (current) into one or more different voltages (currents) with the same frequency. Transformers must be used in a transformer cabinet; in other words, the transformer must be housed in an enclosed cabinet for isolation and protection.

[0003] In existing technology, transformer cabinets mainly consist of a metal frame and wall panels fixed to the various sides of the metal frame. The manufacturing process involves first assembling a frame using a number of profiles, and then welding the wall panels to the six sides of the frame. The technical problems with this frame structure are: 1. Although the metal frame assembled from profiles has good structural strength, the profiles are relatively expensive, resulting in high cost and poor economic efficiency for the transformer cabinet. 2. The manufacturing process is complex and assembly is cumbersome. Summary of the Invention

[0007] Preferably, the bending structure includes a first bending segment, a second bending segment, a third bending segment, a fourth bending segment, and a fifth bending segment formed by connecting bending lines, wherein the bending angle between the second bending segment and the third bending segment is 180°, and the assembly step is formed by overlapping the second bending segment and the third bending segment, and the assembly step is parallel to the plate.

[0008] The reinforcing tube is formed by the first bending section, the third bending section, the fourth bending section, and the plate; the fifth bending section is welded and fixed to the inner side of the plate.

[0009] Preferably, the bending structure includes a sixth bending segment, a seventh bending segment, an eighth bending segment, a ninth bending segment, and a tenth bending segment formed by connecting bending lines, wherein the bending angle between the eighth bending segment and the ninth bending segment is 180°, and the assembly step is formed by overlapping the eighth bending segment and the ninth bending segment, and the assembly step is perpendicular to the plate.

[0010] The reinforcing tube is formed by the sixth bend, the seventh bend, the ninth bend, and the plate; the tenth bend is welded and fixed to the inner side of the plate.

[0011] Preferably, the assembly step has first connecting holes distributed on it.

[0012] The second objective of this invention is to provide a transformer cabinet, including a front side plate, a rear side plate, a left side plate, a right side plate, a top plate, and a base. The key point is that each of the front side plate, rear side plate, left side plate, right side plate, and top plate includes several of the aforementioned plates. The front side plate and the left side plate, the front side plate and the right side plate, the rear side plate and the left side plate, the rear side plate and the right side plate, the top plate and the front side plate, the top plate and the rear side plate, the top plate and the left side plate, and the top plate and the right side plate are all connected by bolts at the assembly step position.

[0013] Preferably, the front side plate, rear side plate, left side plate, right side plate, and top plate are provided with flange structures at the positions corresponding to the assembly steps. The flange structure includes a first flange and a second flange that are bent vertically in sequence. The second flange has second connecting holes distributed on it, and the second flange is fixedly connected to the assembly step by bolts.

[0014] Preferably, the base includes four sets of rectangularly distributed side beam components. The side beam components have an "L" shaped cross-section and are provided with a support platform and a first connecting plate that are bent in sequence at their upper ends. The first connecting plate extends upward, and the lower inner sides of the front side plate, rear side plate, left side plate, and right side plate are fixed to the first connecting plate by bolts.

[0015] Preferably, a perforated plate is installed inside the base formed by the four sets of side beam components.

[0016] A third objective of this invention is to provide a method for manufacturing a transformer cabinet, the method comprising the following steps:

Compared with traditional transformer cabinets, this cabinet eliminates the need for a profile frame, resulting in advantages such as low cost and simple manufacturing process.

[0026] 3. The production of the entire transformer cabinet only requires sheet metal as raw material, which is inexpensive and economical. Attached Figure Description

[0036] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0037] Example 1

[0038] like Figure 3 As shown, a plate 1 has a bent structure 1a integrally formed at its end using a bending process, combined with an attached... Figure 1 As can be seen, the bending structure 1a forms a reinforcing tube 1a1 and an assembly step 1a2. The reinforcing tube 1a1 is constructed as a rectangular hollow structure and is formed on the inner side of the end of the plate 1. The assembly step 1a2 extends outward from one side of the reinforcing tube 1a1. The assembly step 1a2 has first connecting holes 1b distributed on it, which are used for mounting bolts.

[0039] The above-mentioned plate 1 is used in transformer cabinets and can be directly used as the wall panel for each side, combined with the attached... Figure 4 As can be seen, the reinforcing tube 1a1 of the bent structure 1a can form a support column at the edge position, ensuring that the transformer cabinet has sufficient structural strength. The assembly step 1a2 allows adjacent plates to support each other and be securely connected. In this way, the entire transformer cabinet can be assembled directly using multiple plates 1. Compared with traditional transformer cabinets, it eliminates the need for a metal frame and has the advantages of low cost and simple process.

[0040] This embodiment provides two application methods for the bending structure 1a, as follows:

[0041] Application Method 1: Please refer to Figure 1 The bending structure 1a includes a first bending segment a, a second bending segment b, a third bending segment c, a fourth bending segment d, and a fifth bending segment e formed by bending along a line. The bending angle between the second bending segment b and the third bending segment c is 180°. The assembly step 1a2 is formed by overlapping the second bending segment b and the third bending segment c. The assembly step 1a2 protrudes outward and is parallel to the plate 1. (See attached diagram.) Figure 5 It can be seen that the bending structure 1a of this structural form can realize the expansion of the plate 1 and increase the area of ​​a single wall panel of the transformer cabinet. Specifically, one plate 1 overlaps the assembly step 1a2 of another plate 1, and the expansion connection can be achieved by bolts 5.

[0042] In this application, the reinforcing tube 1a1 is formed by the first bent section a, the third bent section c, the fourth bent section d, and the plate 1. The fifth bent section e is welded and fixed to the inner side of the plate 1.

[0043] Application Method Two: Please refer to Figure 2The bending structure 1a includes a sixth bending segment f, a seventh bending segment g, an eighth bending segment h, a ninth bending segment i, and a tenth bending segment j, formed by bending along a line. The bending angle between the eighth bending segment h and the ninth bending segment i is 180°. The assembly step 1a2 is formed by overlapping the eighth bending segment h and the ninth bending segment i. The assembly step 1a2 protrudes downward and is perpendicular to the plate 1. (See attached...) Figure 4 It can be seen that the bending structure 1a of this type of structure can be used for fastening between adjacent wall panels of the transformer cabinet. Specifically, the upper end of the right side plate D of the transformer cabinet is attached to the mounting step 1a2 of the top plate E, and then the connection can be fixed by bolts 5.

[0044] In this application, the reinforcing tube 1a1 is formed by the sixth bend segment f, the seventh bend segment g, the ninth bend segment i, and the plate 1. The tenth bend segment j is welded and fixed to the inner side of the plate 1.

[0045] Example 2

[0046] like Figure 6 and 7 As shown, a transformer cabinet includes a front panel A, a rear panel B, a left panel C, a right panel D, a top panel E, and a base F. Depending on the actual size of the cabinet, the front panel A, rear panel B, left panel C, right panel D, and top panel E are each composed of a number of panels 1. The front panel A and left panel C, the front panel A and right panel D, the rear panel B and left panel C, the rear panel B and right panel D, the top panel E and front panel A, the top panel E and rear panel B, the top panel E and left panel C, and the top panel E and right panel D are all connected by bolts at the mounting step 1a2.

[0047] For ease of installation, the front side panel A, rear side panel B, left side panel C, right side panel D, and top panel E are provided with flange structures 2 at the positions corresponding to the mounting steps 1a2. This embodiment uses the connection between the right side panel D and the top panel E as an example to illustrate the flange structure 2. Please refer to the attached document. Figure 4 As shown, the flange structure 2 includes a first flange 2a and a second flange 2b that are bent vertically in sequence. The second flange 2b has second connecting holes 2c. During assembly, bolts 5 are passed through the first connecting holes 1b of the assembly step 1a2 and the second connecting holes 2c of the second flange 2b to achieve a tight connection between the right side panel D and the top panel E. Furthermore, this assembly method allows the bolt shank to be hidden between the second flange 2b and the panel 1, preventing the bolt from being exposed outside the cabinet and resulting in a better appearance.

[0048] Please refer to Figure 8 In this embodiment, the base F of the transformer cabinet includes four sets of side beam components 3, which form a rectangular base frame. A perforated plate 4 is installed inside the rectangular base frame. Combined with... Figure 9As can be seen, the cross-section of the side beam component 3 is "L" shaped. The upper end of the "L" shape is provided with a support platform 3a and a first connecting plate 3b formed by sequential bending. The first connecting plate 3b extends upward, and the lower ends of the front side plate A, rear side plate B, left side plate C, and right side plate D are fixed to the first connecting plate 3b by bolts. To facilitate the connection between adjacent sets of side beam components 3, a third flange 3c is provided at the end of the side beam component 3.

[0049] Example 3

[0050] A method for manufacturing a transformer cabinet includes the following steps:

[0051] S1, Cutting: Based on the required number and size of the front panel A, rear panel B, left panel C, right panel D, and top panel E, cut the materials into several pieces.

[0052] S2, punching: First, calculate the distribution positions of the first connecting hole 1b and the second connecting hole 2c on the sheet metal, and then punch the holes on the punch press;

[0053] S3, bending: The sheet metal is bent on the bending machine according to the preset bending line, so that the corresponding end of the sheet metal forms a bending structure 1a;

[0054] S4. According to the preset dimensions, assemble the various panels into the required front panel A, rear panel B, left panel C, right panel D, and top panel E.

[0055] S5, four sets of side beam components 3 are manufactured using a bending process, and then the four sets of side beam components 3 are assembled into a base F;

[0056] S6, the front side plate A, rear side plate B, left side plate C, right side plate D, top plate E obtained in step S4 and the base F obtained in step S5 are connected by bolts to form a transformer cabinet.

[0057] Manufacturing transformer cabinets using the above method requires only sheet metal as raw material, resulting in lower costs and better economic efficiency compared to using profiles. It also offers advantages such as simpler processes and easier assembly. Furthermore, although the transformer cabinet does not use profiles as a frame, the reinforcing tube 1a1, bent at the end of the sheet metal 1, still ensures excellent structural strength and high practical value.

[0058] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
