Description

Technical Field

[0001] This utility model relates to the field of transformer beam positioning technology, specifically an energy-saving transformer beam positioning device. Background Technology

[0002] The transformer top beam positioning device is a key component ensuring precise connection between the transformer body and the tank cover, improving overall stability and energy efficiency. It ensures that the top beam and tank cover are not misaligned laterally or axially, preventing increased leakage flux and localized overheating due to installation errors, thereby reducing no-load losses. Medium and large oil-immersed power transformers are among the main equipment in power systems. In recent years, the transformer market has become increasingly competitive, making cost reduction and material consumption an inevitable trend, and optimizing the internal structure of transformers imperative.

[0003] In existing technologies, such as the crossbeam positioning seat for a transformer core clamp disclosed in publication number CN207441431U, there is a positioning plate a, and a positioning plate b is integrally connected to the center of the positioning plate a. The positioning plate b is a cylindrical structure with through holes forming a groove structure. The groove structure formed by the through holes in the positioning plate b collects metal foreign objects generated by friction between the pressure pins and the seat holes, preventing them from falling onto the core surface and effectively controlling the potential hazards caused by metal foreign objects in the transformer.

[0004] The existing device forms a groove structure through the through hole on the positioning plate b, which collects the metal foreign objects generated by the friction between the pressure pin and the seat hole in the groove, making it less likely to fall onto the iron core surface. However, it is inconvenient to position it according to the opening size and flange size on the transformer tank cover during use. When installing and disassembling the transformer, it cannot guarantee the fixation and positioning of the transformer body and the tank. Utility Model Content

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0024] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides an energy-saving transformer upper beam positioning device, including: a device frame 1, a reinforcing plate 2, and fixing bolts 3; the reinforcing plate 2 is fixed below both ends of the device frame 1, and the fixing bolts 3 are disposed on the upper surface of the device frame 1 and threadedly connected to the reinforcing plate 2, and also includes: The device includes a positioning component, an auxiliary component, and a reinforcing component. The positioning component is located at the upper end of the device frame 1, the auxiliary component is located at the lower end of the device frame 1, and the reinforcing component is located at both ends of the auxiliary component.

[0025] Specifically, the positioning components include: upper beam positioning component 4, upper beam positioning cover 41, positioning rod 42, limiting ring 43, limiting groove 44, threaded hole 45 and limiting bolt 46. The upper beam positioning component 4 is welded and fixed to the upper end of the device frame 1. The upper beam positioning cover 41 is placed on the upper surface of the upper beam positioning component 4. The lower end of the upper beam positioning cover 41 is welded with a positioning rod 42. The outside of the positioning rod 42 is provided with a limiting ring 43 that is fixedly connected to the upper beam positioning cover 41.

[0026] Furthermore, the upper beam positioning cover 41 is installed on the upper beam positioning component 4. The limiting ring 43 and the limiting groove 44 can play an auxiliary positioning role, so that the positioning rod 42 at the lower end of the upper beam positioning component 4 is inserted into the positioning hole 54 in the limiting pad 53.

[0027] Specifically, the lower end of the limiting ring 43 is connected to a limiting groove 44 opened on the upper beam positioning member 4, the outer wall of the upper beam positioning member 4 is provided with a threaded hole 45, and the upper surface of the upper beam positioning cover 41 is installed with a limiting bolt 46, and the limiting bolt 46 and the threaded hole 45 are threadedly connected.

[0028] Furthermore, by tightening the limiting bolt 46, the limiting bolt 46 is connected to the threaded hole 45, thereby fixing the upper beam positioning cover 41. Then, putty is placed into the device to fill it. After the putty has cured, the transformer tank is connected and fixed to the transformer body to form a whole.

[0029] In use, the device frame 1 is installed. First, the upper beam positioning cover 41 is installed on the upper beam positioning component 4. The limiting ring 43 and the limiting groove 44 can play an auxiliary positioning role, so that the positioning rod 42 at the lower end of the upper beam positioning component 4 is inserted into the positioning hole 54 in the limiting pad 53. By tightening the limiting bolt 46, the limiting bolt 46 is connected to the threaded hole 45, thereby fixing the upper beam positioning cover 41. Then, putty is put into the device and filled in. After the putty cures, the transformer tank is connected and fixed to the transformer body to form a whole, ensuring the integration of the transformer. The reinforcing plate 2 and fixing bolt 3 can enhance the strength of the device. This device connects and fixes the transformer tank to the transformer body together, so that the transformer will not be displaced due to vibration during transportation, and the height of the transformer tank is reduced to save the amount of oil in the transformer. When the transformer is disassembled later, it is not necessary to disassemble this device in advance to meet the disassembly and assembly of the transformer.

[0030] In summary, when using this energy-saving transformer upper beam positioning device, the positioning rod 42 at the lower end of the upper beam positioning component 4 is inserted into the positioning hole 54 in the limiting pad 53. By tightening the limiting bolt 46, the limiting bolt 46 is connected to the threaded hole 45, thereby fixing the upper beam positioning cover 41. Then, putty is put into the device to fill it. After the putty cures, the transformer tank is connected and fixed to the transformer body to form an integral unit, ensuring the integration of the transformer.

[0035] Furthermore, tighten the fixing screws 63 on the side plate 62 to connect and fix the side plate 62 to the upper beam 5 of the transformer.

[0036] In use, the transformer upper beam 5 is assembled onto the transformer, and then the seamless tube 51 is welded to the transformer upper beam 5 using welding equipment. Then, the limiting pad 53 is placed into the seamless tube 51. The strength of the seamless tube 51 is enhanced by the reinforcing rib 52. The fixing screws 63 on the side plate 62 are tightened by using tools through the mounting holes 61 on the fixing strip 6, thereby connecting and fixing the side plate 62 to the transformer upper beam 5.
