[0030] Embodiment three: See also Figure 9-10On the basis of the first and second embodiments, the heat dissipation mechanism 4 further comprises a heat dissipation groove, the heat dissipation grooves are both provided on both sides of the shell 1, a rectangular shell 46 is fixedly connected in the heat dissipation groove, a condensation plate 43 is fixedly connected in the rectangular shell 46, a supply fan 47 is fixedly connected on the side of the condensation plate 43 away from the transformer body 5, an output shaft is fixedly connected to the inner circle of the supply fan 47, a second motor 44 is fixedly connected on the side of the output shaft away from the condensation plate 43, and the second motor 44 is arranged at the center of the rectangular shell 46.

[0031] Furthermore, a connecting frame 45 is fixedly connected to the surface of the second motor 44, and the connecting frame 45 is fixedly connected to the rectangular shell 46. The connecting frame 45 is rotatably connected to the surface of the output shaft.

[0032] Furthermore, a groove is provided on the surface of the rectangular shell 46, and a first dustproof net 42 is inserted into the groove.

Under the action of the first dustproof net 42, external dust can be prevented from entering and affecting the use of the transformer body 5.

[0033] Furthermore, a number of condensation plates 43 are arranged, and the condensation plates 43 are evenly spaced. When air passes through the condensation plates 43 , it is converted into cold air. At this time, the cold air fills around the transformer body 5 and can dissipate heat for the transformer body 5 .

[0034] In actual operation, when this device is used, first of all, in the entire transformer installation system, there is a set of ingeniously designed structures to ensure the convenient installation and removal process of the transformer body 5. First, we focus on the installation link. Through a specially designed mechanical device, the transformer body 5 is carefully placed on the top of the support seat 23. This support seat 23 is carefully built. It has sufficient strength and stability to withstand the weight of the transformer body 5. In this process, the rollers 21 located at the bottom of the support seat 23 begin to play a key role. The rollers 21 are placed in the slide rails 22 inside the installation shell 25. These rollers 21 are well-made, with a smooth surface and hard material, and can slide smoothly inside the slide rails 22; When the roller 21 starts to slide inside the slide rail 22, the whole device is like starting a precise mechanical dance. The roller 21 moves slowly along the slide rail 22. Each rolling brings the whole device one step closer to the goal of installation completion. When the roller 21 slides to a pre-set specific position, an important step starts - starting the first motor 206. As a power source, the first motor 206 has stable and efficient performance. After starting, it can drive the flat gear 204 to rotate. This flat gear 204 is one of the core components of the entire transmission link. Its gear teeth are precisely processed and maintain a perfect mutual meshing state with the toothed plates 202 on both sides; When the flat gear 204 starts to rotate, the precise fit between its gear teeth and the toothed plate 202 demonstrates the charm of mechanical transmission. Due to this close meshing relationship, the rotational motion of the flat gear 204 can be quickly converted into the linear motion of the toothed plate 202, driving the toothed plates 202 on both sides to move in directions away from each other. At this time, the carefully designed limiters 205 on both sides begin to play a role. These limiters 205 are perfectly matched with the surface design of the roller 21. When the toothed plate 202 moves into place, they are closely fitted with the surface of the roller 21. This fit is not a simple contact, but a precise limit mechanism, which can effectively limit the roller 21 and ensure that the roller 21 will not be displaced unnecessarily in the subsequent process, thereby ensuring the stability of the entire device. At the same time, when the roller 21 slides inside the slide rail 22, there are other parts working together, among which the T-plate can be accurately inserted into the inside of the T-shell. The design of this T-shaped structure increases the stability and guidance of the connection. In addition, in this process, the limit rod 33 can also be accurately inserted into the limit groove opened inside the support plate 34. The size and shape of the limit rod 33 are completely matched with the limit groove. This precise matching ensures the firmness of the connection. Then, by threading the locking nut to the surface of the limit rod 33, this series of operations is like adding a solid "safety lock" to the entire installation process, which can fix the transformer body 5 in all directions. In this fixed state, even if the transformer body 5 is affected by various external factors during operation, such as slight vibration, there will be no random deviation, thereby ensuring the normal operation of the transformer; It can be seen from the above detailed installation principle that when the transformer body 5 needs to be disassembled, it is only necessary to follow the reverse steps. This design that is easy to install and disassemble greatly facilitates maintenance personnel to inspect and repair the transformer body 5 when it is damaged. The maintenance personnel can quickly remove the transformer from the installation position and send it to a special maintenance area for inspection and repair, which effectively shortens the maintenance time and reduces the power outage time caused by transformer failure. In addition to the convenient installation and disassembly functions, this transformer system also has an excellent heat dissipation design to cope with the overheating problem that may occur when the transformer body 5 works for a long time. When the transformer body 5 inside the housing 1 runs for a long time and its own heat gradually increases, the heat dissipation mechanism starts to start. Among them, the second motor 44 plays an important role. The second motor 44 also has reliable performance. After starting, it can drive the supply fan 47 to rotate. The blades of the supply fan 47 are scientifically designed and can generate stable and strong airflow during the rotation process. Under the rotation of the supply fan 47, the external air is continuously introduced. The air must first pass through the first dustproof net 42, which is a very critical component. The first dustproof net 42 has a fine mesh structure, which can effectively block dust particles in the external air. If these dust enter the inside of the shell 1, they may adhere to the surface or internal components of the transformer body 5, thereby affecting the normal use of the transformer body 5, such as reducing the heat dissipation efficiency and causing electrical failures. When the air after the dustproof treatment enters the inside of the shell 1, it will continue to flow. When the air passes through the condensation plate 43, a wonderful physical change occurs. The condensation plate 43 uses special materials and designs, which can quickly reduce the temperature of the air and convert the air itself into cold air. These cold airs quickly diffuse inside the shell 1 and fill around the transformer body 5, just like putting on a "cool coat" for the transformer body 5. They can effectively absorb the heat emitted by the transformer body 5, thereby efficiently dissipating the heat of the transformer body 5. Through this heat dissipation method, the transformer body 5 itself is prevented from malfunctioning due to excessive heat, which greatly improves the service life of the transformer body 5 and ensures the stable operation of the power system.
