[0002] As a crucial piece of equipment in the power system, the transformer's main function is to change AC voltage to meet different electricity demands. In the process of power transmission and distribution, the transformer plays an indispensable role, effectively reducing energy loss during transmission and improving power supply efficiency. A transformer mainly consists of an iron core, coils, and a casing.

[0003] Most existing transformer casings use traditional fixed connection methods, such as bolt fastening and welding. Although this connection method can ensure the stability and sealing of the casing, it requires a lot of time and effort to disassemble the casing when maintaining the iron core and coil inside the transformer, which cannot meet the usage requirements. Therefore, we propose a transformer that facilitates the maintenance of the iron core and coil. Utility Model Content

It has the advantage of being easy to maintain the core and coils, and solves the problem that most existing transformer shells adopt traditional fixed connection methods, such as bolt fastening and welding. Although this connection method can ensure the stability and sealing of the shell, it requires a lot of time and effort to disassemble the shell when maintaining the core and coils inside the transformer, which cannot meet the usage requirements.

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 or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a transformer that facilitates the maintenance of the core and coils, including a lower shell 1, an upper shell 2 on the top of the lower shell 1, hollow blocks 3 fixedly connected to both sides of the upper shell 2, a rotating shaft 4 movably connected to one side of the hollow blocks 3, a driving gear 5 fixedly connected to the surface of the rotating shaft 4, a driven gear 6 meshing with the rear side of the driving gear 5, a connecting shaft 7 fixedly connected to the inner cavity of the driven gear 6, a connecting frame 8 fixedly connected to the bottom of both the rotating shaft 4 and the connecting shaft 7, a fixing plate 10 provided on the other side of the connecting frame 8, one side of the fixing plate 10 fixedly connected to the lower shell 1, a shell 11 fixedly connected to both sides of the lower shell 1, a spring 12 fixedly connected to the bottom of the inner cavity of the shell 11, and a connecting... A pin 14 is fixedly connected to the top of the connecting plate 13. The top of the pin 14 passes through the connecting frame 8 and the fixing plate 10 and extends to the top of the fixing plate 10. A crossbar 15 is fixedly connected to the surface of the pin 14. One side of the rotating shaft 4 and the connecting shaft 7 are movably connected to the hollow block 3 through bearings. A handle is fixedly connected to the top of the rotating shaft 4. A connecting pin is fixedly connected to the top of the lower shell 1, and the surface of the connecting pin is inserted into the upper shell 2. A round hole is opened on the top of the shell 11, and the inner cavity of the round hole is slidably connected to the pin 14. A sealing gasket is provided on the top of the lower shell 1. Heat dissipation fins are fixedly connected to the front and back of the lower shell 1 and the upper shell 2. A magnetic block 9 is in contact with one side of the connecting frame 8, and the top of the magnetic block 9 is fixedly connected to the hollow block 3.

[0025] The specific function of this technical solution is as follows: When maintenance is required, the horizontal bar 15 is moved downwards, which causes the pin 14 to move away from the connecting frame 8. Then, the rotating shaft 4 is rotated, which drives the driving gear 5 to rotate. The driving gear 5 drives the driven gear 6 to rotate, which drives the connecting shaft 7 to rotate. This causes the connecting frame 8 to rotate, moving it away from the fixed plate 10. Then, the upper shell 2 can be moved upwards, separating it from the lower shell 1, and maintenance work can then be performed.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, the bottom of the lower shell 1 is provided with a base plate 16, and the four corners of the top of the base plate 16 are fixedly connected with fixing seats 17.

An elastic telescopic rod 21 is fixedly connected to one side of the card seat 22. A connecting seat 20 is fixedly connected to one side of the elastic telescopic rod 21. The top of the connecting seat 20 is fixedly connected to the lower shell 1.

[0028] The specific function of this technical solution is as follows: During installation, the elastic telescopic rod 21 is retracted, and then the fixed seat 17 and the rectangular block 18 are connected by the bolt 19. Then the elastic telescopic rod 21 is loosened, and the elastic telescopic rod 21 drives the card seat 22 to move, so that the card seat 22 is inserted into the bolt 19, which can limit the bolt 19 and prevent the bolt 19 from loosening, thus making the operation stable.

[0029] Working principle: When maintenance is required, move the crossbar 15 downwards. The crossbar 15 drives the pin 14 to move away from the connecting frame 8. Then rotate the rotating shaft 4. The rotating shaft 4 drives the driving gear 5 to rotate. The driving gear 5 drives the driven gear 6 to rotate. The driven gear 6 drives the connecting shaft 7 to rotate, which in turn drives the connecting frame 8 to rotate away from the fixed plate 10. Then the upper shell 2 can be moved upwards to separate the upper shell 2 from the lower shell 1, and then maintenance work can be carried out.

[0030] During installation, the elastic telescopic rod 21 is retracted, and then the fixed seat 17 and the rectangular block 18 are connected by the bolt 19. Then the elastic telescopic rod 21 is loosened, and the elastic telescopic rod 21 drives the card seat 22 to move, so that the card seat 22 is inserted into the bolt 19, which can limit the bolt 19 and prevent the bolt 19 from loosening, thus ensuring stability during operation.
