Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and more specifically, to an axially split filter winding rectifier transformer. Background Technology
[0002] A rectifier transformer is a power transformer used in rectifier equipment. The characteristic of rectifier equipment is that it takes AC input as the primary side and outputs DC after passing through rectifier elements. Converter technology encompasses three operating modes: rectification, inversion, and frequency conversion, with rectification being the most widely used. The transformer used as the power supply for a rectifier device is called a rectifier transformer. Most industrial rectified DC power supplies are obtained from the AC power grid through rectifier transformers and rectifier equipment.
[0003] Currently, some existing axially split filter winding rectifier transformers generate a certain amount of heat during operation. This heat is difficult to dissipate, and if it accumulates, it will damage the transformer and shorten its service life. To address this, we propose an axially split filter winding rectifier transformer. Utility Model Content
[0004] The purpose of this invention is to provide an axially split filter winding rectifier transformer to solve the problems mentioned in the background art.
[0005] Currently, some existing axially split filter winding rectifier transformers generate a certain amount of heat during operation. This heat is difficult to dissipate, and if it accumulates, it will damage the transformer, thereby shortening its service life.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An axially split filter winding rectifier transformer includes a housing with a door rotatably connected inside. A transformer body is fixedly installed inside the housing. A rotating shaft is rotatably connected inside the housing and above the transformer body. A rotating plate is sleeved on the outside of the rotating shaft and fixedly connected to the rotating shaft. A sliding groove is formed inside the rotating plate, and an air supply pipe is slidably connected inside the sliding groove. A blower pipe is fixedly connected to the outside of the air supply pipe near the transformer body and communicates with the air supply pipe. A groove is formed inside the housing, and the air supply pipe passes through the sliding groove and extends into the groove, slidably connected to the groove.
[0008] Preferably, the groove has a rectangular structure, and the outer wall of the air supply pipe fits into the inner wall of the groove.
[0009] Preferably, a limiting groove is provided inside the rotating plate and on both sides of the air supply pipe, and a limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the air supply pipe.
[0010] Preferably, both the limiting groove and the limiting block have rectangular cross-sections, and the outer sidewall of the limiting block fits against the inner sidewall of the limiting groove.
[0011] Preferably, a mounting plate is fixedly connected to the top of the housing, a cooler is fixedly connected to the top of the mounting plate, a flexible hose is provided between the cooler and the air supply pipe, one end of the flexible hose is fixedly connected to the air supply pipe, and the other end of the flexible hose is fixedly connected to a rotary joint, which is fixedly connected to the air outlet of the cooler.
[0012] Preferably, a motor is fixedly connected to the top of the mounting plate, the output shaft of the motor vertically penetrates the mounting plate and extends to the inner side of the mounting plate, the output shaft of the motor is rotatably connected to the mounting plate, a first gear is fixedly connected to the output end of the motor, a second gear is sleeved on the outside of the rotating shaft, the second gear is fixedly connected to the rotating shaft, and the second gear meshes with the first gear.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The air cooler delivers cool air through a flexible hose into the air supply duct. The cool air is then sprayed out from a blower pipe on one side of the air supply duct, spraying onto the transformer body to cool it down. Simultaneously, the motor starts, and the motor drives the rotating shaft and rotating plate through the first and second gears. The rotating plate drives the air supply duct to rotate. Due to the confinement of the groove, the air supply duct rotates around the transformer body. Moreover, the groove has a rectangular structure, which adapts to the transformer body, ensuring that the air supply duct always maintains the same distance from the transformer body. Whether on the side or at the corner, this ensures a cooling effect and prevents the heat generated during the transformer's operation from damaging the transformer body, thus ensuring the transformer's service life.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 An axially split filter winding rectifier transformer includes a housing 1, a door 2 rotatably connected inside the housing 1, a transformer body 3 fixedly installed inside the housing 1, a rotating shaft 4 rotatably connected inside the housing 1 and above the transformer body 3, a rotating plate 5 sleeved on the outside of the rotating shaft 4, the rotating plate 5 being fixedly connected to the rotating shaft 4, a sliding groove 6 opened inside the rotating plate 5, an air supply pipe 7 slidably connected inside the sliding groove 6, and a blower pipe 8 fixedly connected to the outside of the air supply pipe 7 near the transformer body 3, multiple blower pipes 8 are arranged vertically, the blower pipes 8 are connected to the air supply pipe 7, a groove 9 opened inside the housing 1, the air supply pipe 7 passes through the sliding groove 6 and extends into the groove 9, the air supply pipe 7 is slidably connected to the groove 9, when the rotating plate 5 rotates, it will drive the air supply pipe 7 to slide in the groove 9, so that the air supply pipe 7 rotates around the transformer body 3, and cold air is sprayed onto the transformer body 3 through the blower pipe 8 on the air supply pipe 7 to achieve the purpose of cooling the transformer body 3.
[0022] Furthermore, the groove 9 has a rectangular structure, and the outer wall of the air supply pipe 7 fits into the inner wall of the groove 9. When the rotating plate 5 rotates, it will drive the air supply pipe 7 to rotate around the transformer body 3. Since the rectangular groove 9 is compatible with the transformer body 3, the air supply pipe 7 can always maintain the same distance from the transformer body 3, whether on the side or at the corner, to ensure the cooling effect.
[0023] Furthermore, a limiting groove 10 is provided inside the rotating plate 5 and on both sides of the air supply pipe 7. A limiting block 11 is slidably connected inside the limiting groove 10. The limiting block 11 is fixedly connected to the air supply pipe 7. The limiting groove 10 and the limiting block 11 limit the air supply pipe 7 and the slide 6, preventing the air supply pipe 7 from coming out of the slide 6. Under the action of the limiting groove 10 and the limiting block 11, the air supply pipe 7 will only move in a straight line within the slide 6.
[0024] Furthermore, both the limiting groove 10 and the limiting block 11 have rectangular cross-sections. The outer wall of the limiting block 11 fits against the inner wall of the limiting groove 10. The rectangular cross-section allows the limiting block 11 to slide back and forth in a straight line within the limiting groove 10 without rotation, thus preventing the air supply pipe 7 from deflecting towards the transformer body 3 or away from the transformer body 3.
[0025] Furthermore, a mounting plate 12 is fixedly connected to the top of the housing 1, and a cooler 13 is fixedly connected to the top of the mounting plate 12. A flexible hose 14 is provided between the cooler 13 and the air supply pipe 7. One end of the flexible hose 14 is fixedly connected to the air supply pipe 7, and the other end of the flexible hose 14 is fixedly connected to a rotary joint 15. The rotary joint 15 is fixedly connected to the air outlet of the cooler 13. The flexible hose 14 passes through the interior of the rotating shaft 4 and the rotating plate 5, connecting the cooler 13 and the air supply pipe 7. Since the rotating shaft 4 needs to rotate, a rotary joint 15 is provided between the air outlet of the cooler 13 and the flexible hose 14 to ensure that the cool air is delivered normally without causing the flexible hose 14 to twist or become entangled.
[0026] Furthermore, a motor 16 is fixedly connected to the top of the mounting plate 12. The output shaft of the motor 16 vertically passes through the mounting plate 12 and extends to the inner side of the mounting plate 12. The output shaft of the motor 16 is rotatably connected to the mounting plate 12. A first gear 17 is fixedly connected to the output end of the motor 16. A second gear 18 is sleeved on the outside of the rotating shaft 4. The second gear 18 is fixedly connected to the rotating shaft 4 and meshes with the first gear 17. The motor 16 directly drives the first gear 17 to rotate. The first gear 17 drives the rotating shaft 4 to rotate through the second gear 18. The rotating shaft 4 drives the rotating plate 5 to rotate. Finally, the rotating plate 5 drives the air supply pipe 7 and the air blowing pipe 8 to rotate around the transformer body 3. The cold air blown out by the air blowing pipe 8 cools the transformer body 3.
[0027] The steps for using this utility model are as follows: When using this axially split filter winding rectifier transformer, start the cooling fan 13. The cooling fan 13 delivers cold air to the air supply pipe 7 through the telescopic hose 14. Then, the cold air is sprayed out from the blower pipe 8 on one side of the air supply pipe 7. The cold air is sprayed onto the transformer body 3 to achieve the purpose of cooling the transformer body 3. At the same time, start the motor 16. The motor 16 drives the first gear 17 to rotate. The first gear 17 drives the rotating shaft 4 to rotate through the second gear 18. The rotating shaft 4 drives the rotating plate 5 to rotate. The rotating plate 5 drives the air supply pipe 7 to rotate. Due to the restriction of the groove 9, the air supply pipe 7 will rotate around the transformer body 3. Moreover, the groove 9 is a rectangular structure, which makes the groove 9 fit the transformer body 3. This ensures that the air supply pipe 7 can always maintain the same distance from the transformer body 3. Whether on the side or at the corner, the cooling effect can be ensured, preventing the heat generated by the transformer body 3 during operation from damaging the transformer body 3 and ensuring the service life of the transformer body 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
