Description

Technical Field

[0001] The utility model relates to a transformer, in particular to a transformer support bar structure. Background Art

[0002] Transformers, as an essential component of power transmission and distribution systems, play a key role in ensuring the stable operation of power grids. To maintain proper functioning of transformers, the heat generated within them must be effectively addressed. Typically, bracing structures are pre-installed during the transformer casting process, allowing for removal after casting to create the necessary heat dissipation channels within the transformer.

[0003] Traditional transformer stay designs typically involve evenly drilling multiple positioning holes in the upper and lower locating rings, and inserting multiple stays into these holes. While this design offers certain conveniences in manufacturing and installation, its main drawback is the small size of the heat dissipation channels formed by the stays, resulting in suboptimal heat dissipation and an inability to effectively dissipate heat from within the transformer.

[0004] Based on this, there is an urgent need for a transformer support structure that can provide a larger heat dissipation channel to enhance the heat dissipation effect of the transformer. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a transformer support bar structure, which can provide a larger heat dissipation channel to enhance the heat dissipation effect of the transformer.

[0006] The basic solution provided by the utility model is: a transformer support structure, comprising an upper positioning ring, a lower positioning ring, and a support assembly arranged between the upper positioning ring and the lower positioning ring; the support assembly comprises a plurality of supports;

[0007] The upper positioning ring and the lower positioning ring are both provided with a plurality of long strip holes for inserting the support bar components.

[0008] The principle and advantage of the utility model are that: in this solution, the upper positioning ring and the lower positioning ring are positioned and fixed by the support rod, and the upper positioning ring and the lower positioning ring are placed in the corresponding transformer casting bucket, and then according to the length of the holes corresponding to the respective elongated holes in the upper positioning ring, the respective stays are inserted into the corresponding elongated holes in sequence to form the corresponding stay assembly, and then casting can be carried out.

[0009] 1. Compared to the traditional design of evenly distributed small holes on the positioning ring for inserting stays, the present invention combines multiple small holes into a long, strip-shaped hole. This allows a single hole to accommodate more stays, connecting the previously independent stays into a single unit and increasing the space occupied by the stays. When the stays are removed after pouring, more ventilation space is left, significantly improving the heat dissipation performance of the transformer.

[0010] 2. The brace assembly of the present invention is composed of multiple braces, and the number of braces can be adjusted according to specific application requirements, thereby giving the brace assembly greater flexibility. This design not only enhances the versatility of the brace assembly and its ability to adapt to various application scenarios, but also effectively reduces production and maintenance costs.

[0011] Furthermore, the struts in the elongated holes are arranged to be unconnected to each other.

[0012] Beneficial effects: In this solution, the unconnected struts can be flexibly adjusted according to actual needs, such as increasing or decreasing the number of struts to adapt to different heat dissipation requirements, thereby improving the versatility and adaptability of the strut structure.

[0013] Since the stays are independent, it is more convenient and quick to maintain or replace them without having to worry about affecting the position or structure of other stays, thus reducing maintenance costs and complexity.

[0014] Furthermore, the struts in the elongated holes are connected in a hinged manner.

[0015] Beneficial effects: In this solution, the hinged connection allows a certain range of motion between the struts, which means that when installing or adjusting the struts, it is easier to adapt to different shape and size requirements, that is, to long strip holes with different curved paths, thereby improving the overall flexibility of the strut structure.

[0016] The stays connected by hinges can better maintain their predetermined positions during the pouring process and are not easily displaced even under the pressure of the pouring material, thereby improving the stability of the stay structure.

[0017] Furthermore, the support bar is provided with a hinge column, and the right side of the support bar is provided with a hinge groove, and the pairing of the hinge column and the hinge groove forms a hinge connection between the support bars.

[0018] Beneficial effects: In this solution, the hinged connection between the struts is achieved by extending the hinged column into the hinged groove. Since the hinged column can rotate in the hinged groove, the struts can adapt to different space requirements during installation. By adjusting the angle of the struts, the struts can be installed in place more easily, and the position of the struts can be adjusted according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a structural diagram of the transformer support structure in Example 1 of the present utility model.

[0020] Figure 2 This is a schematic structural diagram of the support bar assembly in the second embodiment of the present invention. DETAILED DESCRIPTION

[0021] The following is further described in detail through specific implementation methods:

[0022] The symbols in the drawings of the specification include: support bar 1, upper positioning ring 2, long strip hole 3, lower positioning ring 4, hinge column 5, hinge groove 6.

[0023] The embodiment is basically as shown in the attached Figure 1 As shown: A transformer support structure includes an upper positioning ring 2, a lower positioning ring 4, and a support 1 assembly arranged between the upper positioning ring 2 and the lower positioning ring 4; the support 1 assembly includes multiple supports 1; the support 1 is a columnar support 1, and the cross-section of the support 1 is one of a circle, a rectangle, a square, a trapezoid and other polygons. In this embodiment, the cross-section of the support 1 is a rectangle.

[0024] The upper positioning ring 2 and the lower positioning ring 4 are both provided with a plurality of long strip holes 3 for inserting the support bar 1 components.

[0025] The struts 1 in the elongated holes 3 are not connected to each other. In this embodiment, the number of struts 1 that can be inserted into the elongated holes 3 is a positive integer.

[0026] In this embodiment, the entire transformer support bar 1 structure is to be installed in the transformer casting bucket for casting. In order to better fix the upper positioning ring 2 and the lower positioning ring 4 in the casting bucket, mounting holes for the support rod to extend are also opened on the upper positioning ring 2 and the lower positioning ring 4. The upper and lower ends of the support rod are provided with threaded portions that cooperate with the nut threads. By arranging nuts on the upper and lower surfaces of the upper positioning ring 2 and the lower positioning ring 4, the distance between the upper positioning ring 2 and the lower positioning ring 4 is limited.

[0027] First, according to actual needs, several elongated holes 3 are opened at the same position on the upper positioning ring 2 and the lower positioning ring 4. In this embodiment, eight elongated holes 3 are opened, and the corresponding elongated holes 3 have different lengths and are asymmetrical. Of course, in other embodiments, the elongated holes 3 can be the same length and symmetrical, the same length but asymmetrical, or the same length and symmetrical. Then, the support rod is extended into the mounting holes of the upper positioning ring 2 and the lower positioning ring 4, and each elongated hole 3 on the upper positioning ring 2 is aligned with each elongated hole 3 on the lower positioning ring 4.

[0028] The entire structure is then placed into the corresponding transformer casting bucket. The corresponding number of stays 1 can then be sequentially inserted into the respective elongated holes 3 on the upper positioning ring 2, ensuring that the stays 1 completely fill the elongated holes 3. This means that the stays 1 corresponding to the elongated holes 3 are in close contact with each other. Subsequent casting can then proceed. In this embodiment, to facilitate demolding of each stay 1 in the stay 1 assembly after casting, a polyester film coated with a release agent is applied to the inner and outer surfaces of the stay 1 assembly before placement into the transformer casting bucket.

[0029] Example 2

[0030] like Figure 2 As shown, compared with the first embodiment, the difference of this embodiment is that the struts 1 in the elongated holes 3 are connected by hinges. The struts 1 are provided with hinge posts 5, and the right side of the struts 1 is provided with hinge slots 6. The hinge posts 5 and hinge slots 6 are matched to form a hinged connection between the struts 1.

[0031] Compared to the first embodiment, where the struts 1 are individually arranged, this embodiment employs a hinged connection. In this design, the elongated holes 3 in the upper and lower positioning rings 4 can be designed with a curved path. In practice, the hinge post 5 on one strut 1 is inserted into the hinge slot 6 of another strut 1, forming a hinged connection. Because the struts 1 can rotate within a predetermined angle range, when multiple struts 1 are hingedly connected, the entire strut assembly can accommodate elongated holes 3 with varying curved paths.

[0032] In this embodiment, to facilitate the removal of the strut 1 assembly after casting, a support plate is provided at the bottom of the hinge groove 6. A notch corresponding to the height of the support plate is provided at the bottom of the hinge column 5. When the hinge column 5 is fully inserted into the hinge groove 6, the support plate engages with the notch. When it is necessary to remove the strut 1 assembly, it is only necessary to lift a certain strut 1 upward. At this time, the support plate of the hinge groove 6 corresponding to the strut 1 will also lift the strut 1 engaged with its hinge groove 6, thereby lifting the subsequent struts 1 together, thereby achieving simultaneous removal of multiple struts 1, greatly facilitating the demoulding of the strut 1 assembly after casting.

[0033] The above are only embodiments of the present utility model. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date.

Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for technicians in this field, without departing from the structure of the utility model, several variations and improvements can be made, which should also be regarded as the scope of protection of the utility model.
