Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a power transformer with a protection component. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer). Transformers are often provided with heat dissipation fins for heat dissipation. The existing patent application with application number CN202220721969.8 proposes an explosion-proof power transformer. The heat dissipation fins used for heat dissipation lack protective components, which makes the heat dissipation fins on the transformer easily bumped, squeezed and deformed during the installation and transportation of the transformer, and the heat dissipation effect of the deformed heat dissipation fins will deteriorate, which will eventually reduce the heat dissipation efficiency of the transformer. Therefore, a power transformer with a protective component is needed. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a power transformer with a protective component includes a transformer body 1, a plurality of heat sinks 2 are installed on the outer wall of the transformer body 1, and the transformer body 1 and the plurality of heat sinks 2 installed on the outer wall are fixedly connected.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, two U-shaped brackets 3 are fixedly installed on the outer wall of the transformer body 1, and a through hole 6 is opened on the U-shaped bracket 3, and the through hole 6 passes through the U-shaped bracket 3 from top to bottom. An adjustment structure 4 is rotatably installed on the U-shaped bracket 3, and the adjustment structure 4 is composed of a base rod 7, a threaded rod 8 and a baffle 9. There are two threaded rods 8 and they are fixedly installed at the upper and lower ends of the base rod 7, respectively, and there are two baffles 9 and they are fixedly installed at one end of the two threaded rods 8, respectively. The base rod 7 on the adjustment structure 4 is located in the U-shaped bracket 3, and the threaded rod 8 is rotatably installed in the through hole 6. The two baffles 9 are respectively located in On the upper and lower sides of the U-shaped bracket 3, two protective structures 5 are symmetrically and movably sleeved on the transformer body 1. The protective structures 5 are simultaneously mounted on the two threaded rods 8 on the two adjustment structures 4. The protective structure 5 is composed of a rectangular frame 10, a connecting plate 12, and a supporting heat sink 13. There are several connecting plates 12 and they are all fixedly mounted on one end of the rectangular frame 10. There are several supporting heat sinks 13 and they are symmetrically and fixedly mounted on both ends of the connecting plate 12. The supporting heat sink 13 is in contact with the transformer body 1 at the same time. The supporting heat sink 13 can be inserted into two adjacent heat sinks at the same time. The rectangular frame 10 on the protective structure 5 is movably mounted on the transformer body 1, and the two rectangular frames 10 on the two protective structures 5 are respectively located on the upper and lower sides of the heat sink 2. Two threaded holes 11 are provided on the rectangular frame 10, and the rectangular frame 10 is installed on the threaded rod 8 through the threaded holes 11. By setting the U-shaped bracket 3, the adjustment structure 4 and the protective structure 5, when transporting and installing the transformer body 1, the protective structure 5 can be moved by rotating the adjustment structure 4, so that the supporting heat sink 13 on the protective structure 5 is inserted between the two adjacent heat sinks 2, thereby supporting the heat sink 2, and finally reducing the probability of the heat sink 2 being collided, squeezed and deformed during the installation and transportation of the transformer body 1, thereby ensuring that the heat sink 2 and the transformer body 1 have a good heat dissipation effect. At the same time, since the supporting heat sink 13 on the protective structure 5 is in contact with the transformer body 1, the transformer body 1 can also transfer heat to the protective structure 5 when it is working, and then the existence of the protective structure 5 can also accelerate the heat dissipation of the transformer body 1, and finally improve the heat dissipation efficiency of the transformer body 1.

[0022] It should be noted that the utility model is a power transformer with a protective component. During use, when the transformer body 1 needs to be installed and transported, the support heat sink 13 on the protective structure 5 can be inserted between two adjacent heat sinks 2, so as to provide support for the heat sink 2, thereby reducing the probability of deformation of the heat sink 2 due to collision and extrusion. The method for inserting the support heat sink 13 between two adjacent heat sinks 2 is to simply rotate the adjustment structure 4. As the adjustment structure 4 rotates, the two protective structures 5 move on the threaded rod 8, so that the two protective structures 5 are close to each other, and finally until the support heat sink 13 is completely inserted between the two adjacent heat sinks 2; when the transformer body 1 is in use, the support heat sink 13 on the protective structure 5 can be removed from between the two adjacent heat sinks 2, and a certain distance is left between the protective structure 5 and the heat sink 2. At this time, when the transformer body 1 is working, it can conduct heat to the support heat sink 13 on the protective structure 5, and then the protective structure 5 can assist in accelerating the heat dissipation of the transformer body 1, and finally improve the heat dissipation efficiency of the transformer body 1.
