Description

Technical Field

[0001] This utility model relates to the field of transformer design technology, specifically to a power transformer. Background Technology

[0002] The transformer casing is an important component for protecting the transformer. Therefore, the choice of the transformer casing directly affects the transformer's heat dissipation performance, mechanical strength, and protection capability. In order to ensure the heat dissipation of the transformer, the transformer casing is usually equipped with several sets of heat dissipation fins to ensure the transformer's heat dissipation function.

[0003] For example, in the patent document with application number 202421087287.1, an anti-theft power transformer is disclosed, and specifically a design that can judge the performance of the transformer by the condition of the colored lights is disclosed.

[0004] In the above technical solution, the installation of the transformer needs to avoid the location of the transformer heat sink fins and directly hoist the transformer. Under this method, the transformer is very prone to tilting. During installation, it needs to be leveled to ensure that the force of each bolt of the transformer is balanced. The leveling is relatively complicated, making the transformer installation more difficult. Utility Model Content

[0005] The technical problem solved by this utility model is to solve the problem that it is difficult to level transformers in the prior art.

[0006] This utility model can be achieved through the following technical solution: a power transformer, including a transformer body, heat dissipation fins are arranged around the transformer body, a fixed mounting base is fixed on the side of the transformer body, and an extension support for protecting the heat dissipation fins is arranged outside the fixed mounting base, and a number of fin heat dissipation holes are evenly arranged on the extension support.

[0007] A further technical improvement of this utility model is that it also includes a protective housing for supporting and limiting the transformer body, and the protective housing can be detachably installed on the mounting bracket.

[0008] A further technical improvement of this utility model is that the protective shell can be detachably installed on the slide bar, and the mounting bracket has a mounting groove, which is slidably connected to the slide bar.

[0009] A further technical improvement of this utility model is that: a mounting ear plate is fixedly installed on the side of the protective shell, and the mounting ear plate is installed and limited in the mounting groove by mounting bolts.

[0010] A further technical improvement of this utility model is that an internal buffer base for protecting the bottom of the transformer body is fixed inside the protective shell, and the internal buffer base is made of rubber.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This application provides a transformer body with heat dissipation fins around its perimeter and an extension support base fixedly installed on the outside of the heat dissipation fins. The extension support base has several sets of heat dissipation holes evenly distributed on it. In use, the extension support base can protect the heat dissipation fins. During use, the transformer body can be placed inside the protective housing, and the mounting bracket can be directly leveled. During the leveling process, the extension support base can also ensure that the transformer body will not be damaged, thereby ensuring the rapid leveling of the transformer body and solving the problem of difficult transformer leveling in the prior art.

[0013] 2. This application utilizes an internal buffer base to protect the bottom of the transformer body, thereby ensuring the bottom of the transformer body and preventing large deformations caused by vibration during movement. In addition, after the mounting bracket is leveled, the transformer body is removed from the protective shell and placed on the leveled mounting bracket, which facilitates stable installation of the transformer body.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-4 As shown, a power transformer includes a transformer body 1. Several sets of heat dissipation fins are evenly arranged around the transformer body 1 to dissipate heat. To protect the heat dissipation fins, extension support seats 4 are fixedly installed around the transformer body 1. These extension support seats 4 are fixedly mounted on a fixed mounting base 2, which is fixedly mounted on the side of the transformer body 1. The extension support seats 4 have evenly spaced fin ventilation holes 3 for engaging with the heat dissipation fins, ensuring their heat dissipation function. In use, the heat dissipation fins are protected by the extension support seats 4. When the transformer body 1 is moved, the extension support seats 4 protect the heat dissipation fins, ensuring their integrity during transport and preventing significant impacts, thus allowing the transformer body 1 to quickly reach its installation position.

[0022] As a further embodiment of this application, it also includes a mounting bracket 5, on which a protective housing 8 for protecting the transformer body 1 is provided. The protective housing 8 is selected according to the size of the transformer body 1. In use, the transformer body 1 is placed inside the protective housing 8, and then the longitudinal height of the mounting bracket 5 is adjusted. During this process, the extended support 4 on the side of the transformer body 1 is restricted on the protective housing 8 to protect the heat dissipation fins. That is, the mounting bracket 5 may vibrate when it moves longitudinally, thereby protecting the heat dissipation fins and ensuring the integrity of the heat dissipation fins.

[0023] Specifically, a mounting groove 10 is provided on the mounting bracket 5, and a sliding strip is slidably installed inside the mounting groove 10. The sliding strip and the protective housing 8 are detachably connected by bolts, thereby enabling the replacement of the protective housing 8 and the adjustment of the position of the protective housing 8 on the mounting bracket 5 according to the transformer body 1 of different sizes, so as to ensure applicability to transformer body 1 with different requirements.

[0024] During installation, in order to ensure the stability of the protective housing 8, several sets of fixing slots are correspondingly opened on the mounting slot 10. Mounting ear plates 7 are fixedly installed on the side of the protective housing 8. The mounting ear plates 7 and the fixing slots are fixedly connected by mounting bolts to limit the position of the protective housing 8 and the mounting slot 10, so as to ensure the stability of the transformer body 1 inside the protective housing 8 when the longitudinal height of the mounting bracket 5 is adjusted.

[0025] An internal buffer base 6 is fixedly installed at the bottom of the protective housing 8. The internal buffer base 6 is used to protect the bottom of the transformer body 1, that is, to prevent the support frame at the bottom of the transformer body 1 from undergoing large deformation, thereby ensuring that the transformer body 1 will not undergo large deformation during the transfer process and ensuring the appearance of the transformer body 1 remains intact.

[0026] When the mounting bracket 5 is moved to the installation position of the transformer body 1, the transformer body 1 is taken out from the inside of the protective housing 8. That is, in this application, the transformer body 1 is taken out from the inside of the protective housing 8 by the hoisting assembly. Then, the position of the protective housing 8 in the mounting groove 10 is adjusted, and the transformer body 1 is placed directly on the mounting bracket 5 to facilitate the subsequent installation of the transformer body 1.

[0027] Therefore, in this application, the hoisting assembly includes a traction rope 9, with a hook fixed at the end of the traction rope 9. A hoisting bracket 11 is fixed on the mounting bracket 5, and a hoisting platform 12 is fixed at the end of the hoisting bracket 11. A hoisting motor 13 is fixedly installed inside the hoisting platform 12. A hoisting roller 14 is provided at the output end of the hoisting motor 13. The hoisting roller 14 is used to realize the winding function of the traction rope 9. In use, the hook is hung on the extension support 4, and then the hoisting motor 13 is started to control the rotation of the hoisting roller 14, thereby realizing the winding function of the traction rope 9, pulling the transformer body 1 out from the protective shell 8. Then the position of the protective shell 8 is adjusted, and the transformer body 1 is placed directly on the mounting bracket 5.

[0028] As a further embodiment of this application, the hoisting bracket 11 is replaced with a hoisting telescopic rod 15, which can control the height of the hoisting platform 12, thereby further controlling the height of the transformer body 1, making it easier to transfer the transformer body 1 to the mounting bracket 5.

[0029] In use, the transformer body 1 is first placed on the protective housing 8. Then, the height of the mounting bracket 5 is adjusted to facilitate the removal of the transformer body 1 from the inside of the protective housing 8 when it is moved to the installation height. During this process, the hook is hung on the extension support 4. Then, the starting of the hoisting motor 13 controls the rotation of the hoisting roller 14, thereby realizing the winding function of the traction rope 9 and pulling the transformer body 1 out from the inside of the protective housing 8. Then, the position of the protective housing 8 is adjusted, and the transformer body 1 is placed directly on the mounting bracket 5 for easy installation of the transformer body 1.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
