Description

Technical Field

[0001] This utility model relates to the field of combined transformers, specifically a combined transformer that is easy to maintain. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components include a primary coil, a secondary coil, and an iron core. Transformers play a crucial role in power systems and are widely used in power plants, transmission lines, substations, and various electronic devices. A transformer is a static electrical device that converts alternating current of one voltage level into alternating current of another voltage level at the same frequency through electromagnetic induction between coils. Transformers can increase or decrease the voltage of an input circuit, and are called step-up transformers and step-down transformers, respectively. While changing the voltage, the transformer also changes the current accordingly to meet the load requirements. An easy-to-maintain modular transformer ensures its reliability in power systems through its modular design, ease of operation, and safety protection advantages.

[0003] According to Chinese Patent Publication No. CN217847617U, a combined transformer, belonging to the field of transformers, includes a transformer housing and a top cover disposed on the top of the transformer housing. The inner wall of the top cover is spaced apart from the top of the transformer housing for heat dissipation. The outer wall of the transformer housing is also provided with a protective baffle to block rainwater and sand. This utility model's combined transformer, by spaced apart the inner wall of the top cover from the top of the transformer housing, essentially raises the entire top cover, thereby achieving heat dissipation. The protective baffle provides a certain degree of protection against wind, sand, and moisture without affecting ventilation, improving the working environment of the electronic components on the low-voltage side of the combined transformer and thus extending its service life.

[0004] In the above scheme, the inner wall of the top cover is spaced apart from the top of the transformer box to facilitate heat dissipation; the outer wall of the transformer box is also equipped with a protective baffle to block rainwater and sand. This results in the following disadvantages: when the existing combined transformer needs maintenance, the staff directly open the outer protective door. If it rains heavily at this time, rainwater can easily enter the combined transformer and cause electric shock, which increases the difficulty of maintenance, reduces maintenance efficiency, and reduces practicality. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-maintain modular transformer to solve the problem that when maintenance is required, workers directly open the outer protective door of the existing modular transformer, and if it rains heavily at this time, rainwater can easily enter the modular transformer and cause electric shock.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an easy-to-maintain modular transformer, including a housing, a support plate fixedly connected to one side of the housing, a first motor fixedly connected to one side of the support plate, a protective component to prevent rainwater from entering the first motor, a thickened plate installed on the housing, a rotating component to move the transformer on the thickened plate, the protective component including a rotating shaft, the rotating shaft fixedly connected to the output end of the first motor, a first bevel gear fixedly connected to the outer wall of the rotating shaft, a second bevel gear provided on the first bevel gear, the first bevel gear meshing with the second bevel gear, a threaded rod fixedly connected to one side of the second bevel gear, a side plate threadedly connected to the threaded rod, a fixed plate rotatably connected to one end of the threaded rod, the fixed plate fixedly connected to the housing, a third bevel gear fixedly connected to one end of the rotating shaft, a fourth bevel gear provided on the third bevel gear, the third bevel gear meshing with the fourth bevel gear.

[0007] Preferably, a connecting plate is installed on the outer shell, a connecting rod is rotatably connected to the connecting plate, a baffle is fixedly connected to the outer wall of the connecting rod, a rotating plate is fixedly connected to one end of the connecting rod, a fixed rod is slidably connected to the rotating plate, and a circular groove is formed on the outer shell.

[0008] Preferably, the rotating assembly includes a sliding plate slidably connected to a thickened plate, a transformer fixedly connected to the top surface of the sliding plate, a groove formed on the outer casing, a toothed plate slidably connected to the groove, a gear provided on the toothed plate, the gear meshing with the toothed plate, a second motor mounted on the outer casing, a rotating rod fixedly connected to the output end of the second motor, the outer wall of the rotating rod fixedly connected to the gear, an L-shaped plate fixedly connected to one end of the rotating rod, an extension plate fixedly connected to one side of the toothed plate, and the extension plate fixedly connected to the sliding plate.

[0009] Preferably, a buffer column is fixedly connected to the bottom surface of the outer shell, and a groove is provided on the outer shell.

[0010] Preferably, a sensor is fixedly connected inside the housing, and multiple conversion circuits are installed on the sensor.

[0011] Preferably, the transformer is equipped with a voltage regulator, and the outer surface of the voltage regulator is coated with insulating varnish.

[0012] Compared with existing technologies, the easily maintained combined transformer that adopts the above technical solution has the following advantages:

[0013] I. During use, when staff maintain or repair the combined transformer, the first motor is started to drive the rotating shaft to rotate. Then, the rotating shaft drives the first and third bevel gears to rotate. At this time, the first bevel gear drives the second bevel gear, which is meshed with the gear, to rotate. Then, the third bevel gear drives the fourth bevel gear to rotate. At this time, the second and fourth bevel gears drive the threaded rod to rotate. Then, the threaded side plate on the threaded rod begins to move outward in the groove. When the side plate moves to the fixed plate, it stops moving. Then, the rotating plate is rotated to drive the connecting rod to rotate. At this time, the connecting rod drives the baffle to move upward. When the baffle moves to the groove and is horizontally aligned, the rotating plate is stopped rotating. Then, the fixed rod slidably connected on the rotating plate is inserted into the circular groove opened on the outer shell to fix the baffle. This solves the problem that rainwater can easily enter the interior when maintaining the combined transformer. It protects the combined transformer from rainwater damage, effectively blocks rainwater, keeps the inside of the transformer dry, reduces the impact of external environmental factors on the operation of the transformer, enhances equipment safety, reduces maintenance difficulty, and improves maintenance efficiency.

[0014] Second, during use, when staff perform maintenance or repair on the combined transformer, the second motor is started. The second motor then drives the rotating rod to rotate, which in turn drives the gear to rotate. The gear then drives the toothed plate to move outward on the slide groove. The toothed plate then drives the extension plate to move outward, and the extension plate then drives the sliding plate to move outward. The sliding plate then moves the transformer outward, which solves the problem of the combined transformer being difficult to repair inside the casing. This facilitates the maintenance and repair of the combined transformer, thereby improving maintenance efficiency, practicality, flexibility, and safety. Attached Figure Description

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, an easy-to-maintain modular transformer includes a housing 1. A support plate 3 is fixedly connected to one side of the housing 1, and a first motor 4 is fixedly connected to one side of the support plate 3. The first motor 4 is equipped with a protective component to prevent rainwater from entering. A thickened plate 19 is installed on the housing 1, and a rotating component that can move the transformer is provided on the thickened plate 19. The protective component includes a rotating shaft 9, which is fixedly connected to the output end of the first motor 4. A first bevel gear 5 is fixedly connected to the outer wall of the rotating shaft 9, and a second bevel gear 6 is provided on the first bevel gear 5. The first bevel gear 5 and the second bevel gear 6 mesh with each other. One side of the second bevel gear 6... A threaded rod 7 is fixedly connected, and a side plate 18 is threadedly connected to the threaded rod 7. A fixed plate 8 is rotatably connected to one end of the threaded rod 7. The fixed plate 8 is fixedly connected to the outer shell 1. A third bevel gear 10 is fixedly connected to one end of the rotating shaft 9. A fourth bevel gear 11 is provided on the third bevel gear 10. The third bevel gear 10 and the fourth bevel gear 11 mesh. A connecting plate 12 is installed on the outer shell 1. A connecting rod 13 is rotatably connected to the connecting plate 12. A baffle 17 is fixedly connected to the outer wall of the connecting rod 13. A rotating plate 14 is fixedly connected to one end of the connecting rod 13. A fixed rod 15 is slidably connected to the rotating plate 14. A circular groove 16 is provided on the outer shell 1.

[0025] During use, when staff perform maintenance or repair on the combined transformer, the first motor 4 is started, driving the rotating shaft 9 to rotate. The rotating shaft 9 then drives the first bevel gear 5 and the third bevel gear 10 to rotate. At this time, the first bevel gear 5 drives the meshing second bevel gear 6 to rotate, and the third bevel gear 10 drives the fourth bevel gear 11 to rotate. The second bevel gear 6 and the fourth bevel gear 11 then drive the threaded rod 7 to rotate. The threaded side plate 18 on the threaded rod 7 then begins to move outward within the groove 2. The side plate 18 stops moving when it reaches the fixed plate 8, and then the transformer rotates... Plate 14 drives connecting rod 13 to rotate. At this time, connecting rod 13 drives baffle 17 to move upward. Then, baffle 17 moves to the groove 2 and stops rotating. Then, fixed rod 15, which is slidably connected on rotating plate 14, is inserted into the circular groove 16 opened on outer shell 1 to fix baffle 17. This solves the problem that rainwater can easily enter the interior when maintaining combined transformers. It protects the combined transformer from rainwater damage, effectively blocks rainwater, keeps the inside of the transformer dry, reduces the impact of external environmental factors on transformer operation, enhances equipment safety, reduces maintenance difficulty, and improves maintenance efficiency.

[0026] like Figures 1-7 As shown, the rotating assembly includes a slide plate 20, which is slidably connected to a thickened plate 19. A transformer 21 is fixedly connected to the top surface of the slide plate 20. A groove 22 is provided on the outer shell 1, and a toothed plate 23 is slidably connected to the groove 22.

A second motor 25 is installed on the outer shell 1, and a rotating rod 26 is fixedly connected to the output end of the second motor 25. The outer wall of the rotating rod 26 is fixedly connected to the gear 24. An L-shaped plate is fixedly connected to one end of the rotating rod 26. An extension plate 27 is fixedly connected to one side of the toothed plate 23, and the extension plate 27 is fixedly connected to the slide plate 20.

[0027] During use, when staff perform maintenance or repair on the combined transformer, the second motor 25 is started. The second motor 25 then drives the rotating rod 26 to rotate. At this time, the rotating rod 26 drives the gear 24 to rotate, and the gear 24 drives the toothed plate 23 to move outward on the slide groove 22. Then, the toothed plate 23 drives the extension plate 27 to move outward, and the extension plate 27 drives the slide plate 20 to move outward. At this time, the slide plate 20 drives the transformer 21 to move outward. This solves the problem that it is not easy to repair the combined transformer inside the outer casing 1, making it easier to maintain and repair the combined transformer, thereby improving maintenance efficiency, practicality and flexibility, and safety.
