Description

Technical Field

[0001] The present invention relates to the field of three-dimensional wound iron core transformers, in particular to a three-dimensional wound iron core transformer with a heat dissipation structure. Background Art

[0002] The three-dimensional wound core transformer is a transformer that achieves high efficiency and energy saving through innovative core structure. Its core feature is the use of a three-phase integrated three-dimensional wound core. Compared with the traditional laminated core (three phases stacked separately), it has significant advantages in magnetic circuit design, loss control, noise suppression and other aspects.

[0003] Whether it's a three-dimensional wound core transformer or a traditional transformer, optimizing the transformer's heat dissipation performance can effectively improve its energy efficiency. During operation, transformers generate heat due to core losses (hysteresis loss and eddy current loss) and winding losses (resistance loss). If this heat cannot be dissipated promptly, it will cause the transformer's internal temperature to rise, negatively impacting its energy efficiency, lifespan, and safety.

[0004] However, existing three-dimensional wound iron core transformers rely primarily on externally mounted cooling fins for natural heat dissipation. This significantly reduces heat dissipation efficiency when the three-dimensional wound iron core transformer generates significant heat, particularly during hot summer weather. This also impacts operational safety and can lead to malfunctions and damage, resulting in grid power failure.

[0005] The publication number is CN115910573A, which discloses "a transformer, comprising: a transformer body, a sealing plate, a cover, a fiber optic ultrasonic sensor, a fiber optic lead-out line, a UHF sensor, and a UHF sensor lead-out line; a hand hole is provided on the transformer body; the sealing plate covers the hand hole; the cover body covers the sealing plate and encloses a sealed cavity; the cover body has an opening connected to the sealed cavity; the fiber optic ultrasonic sensor and the UHF sensor are arranged in the sealed cavity; the UHF sensor lead-out line and the fiber optic lead-out line pass through the opening and are connected to the UHF sensor and the fiber optic ultrasonic sensor respectively. It effectively solves the problem that the fiber optic ultrasonic sensor and the UHF sensor need to be implanted inside the transformer in the past, and through the structural combination of the fiber optic ultrasonic sensor and the UHF sensor, it can provide joint detection of two signals, thereby improving the effectiveness and accuracy of partial discharge detection, and solving the problem of laying the UHF sensor lead-out line and the fiber optic lead-out line."

[0006] While the above technical solution improves the effectiveness and accuracy of partial discharge detection and solves the problem of laying out UHF sensor and optical fiber lead wires, it still lacks intelligent detection of the transformer's internal temperature and timely and proactive heat dissipation to improve the stability and lifespan of the three-dimensional wound iron core transformer. Therefore, a breathability testing device and method for sanitary napkin development is proposed. Summary of the Invention

[0027] That is, the upper and lower screw rods 20 are rotated and mounted on the upper and lower mounting seats 19 at one end away from each other, while the upper and lower screw rods 20 are close to each other at one end and do not contact each other.

[0028] Example 2: Figures 1-11 As shown, the present invention discloses a three-dimensional wound core transformer with a heat dissipation structure. Compared with the first embodiment, this embodiment discloses the structure of a driving component.

[0029] The driving assembly includes a sprocket 8, a fixed chain 9, a frequency conversion motor 13, and a sprocket 2 14. The sprocket 1 8 is rotatably mounted on the upper and lower sides of the air pump 6.

The outer meshing sleeve of each sprocket 2 14 is provided with a chain 11, and the chain 11 is meshed with each sprocket 1 8.

[0030] By controlling the operation of the variable frequency motor 13, each sprocket 2 14 can be driven to rotate, so that the chain 11 can drive each sprocket 1 8 to rotate, and the other side of the sprocket 1 8 is engaged with the fixed chain 9 fixedly installed on the inner wall of the tank body 3, which can drive the sprocket 1 8 to move in the tank body 3, so that the air pump 6 slides in the slide rail 5, and the air pump 6 is driven to slide back and forth in the slide rail 5 through the forward and reverse rotation of the variable frequency motor 13.

[0031] A support 12 is provided between adjacent slide rails 5, and the support 12 is connected to the inner wall of the trough body 3. The frequency conversion motor 13 is symmetrically installed on the upper and lower sides of the support 12. Guide frames 10 connected to the inner wall of the trough body 3 are also provided on both sides of the slide rail 5, and a chain 11 is wound around the outside of each guide frame 10.

[0032] The support 12 allows the variable frequency motors 13 on the upper and lower sides to be stably mounted thereon, and the guide frame 10 allows the chain 11 to be stably fitted into the trough body 3 and driven by the sprocket 2 14 to rotate stably in the trough body 3.

[0033] Example 3: Figures 1-11 As shown, the present invention discloses a three-dimensional wound core transformer with a heat dissipation structure. Compared with the second embodiment, this embodiment discloses the structure of a linkage component.

[0034] The linkage assembly includes a dial plate 18, a limiting circular groove 24, a slide 25, a slide cylinder 26, a sleeve 27, a cross key 28, a bracket 31, and a rotating plate 32. The dial plate 18 is connected to the upper and lower sides of each folding plate 16. The limiting circular groove 24 is opened at one end of the upper and lower screw rods 20 close to each other. The slide 25 is opened on the side of the upper and lower screw rods 20 close to each other and passes through the limiting circular groove 24. The slide cylinder 26 is slidably sleeved in the limiting circular groove 24, and the slide cylinder 26 passes through the slide 25 and extends outside the screw rod 20. On the other side, the sleeve 27 is rotatably sleeved on the outside of the extended end of the slide 26 on the outside of the screw rod 20, and the cross key 28 is limited and slidably set in the slide 26, and one end passes through the slide 26 and the limiting circular groove 24 and extends between the upper and lower sides of the screw rod 20 close to each other. The bracket 31 is slidably set in the groove body 3, and a rotating plate 32 is rotatably connected between the bracket 31 and the sleeve 27. The dial plate 18 cooperates and contacts with the bracket 31. A synchronization component is provided on the support 12, and the synchronization component is used to cooperate with the cross key 28 for insertion.

[0035] The synchronization component includes a support plate 33, a rotating drum 34, and a chain 2 35. The support plate 33 is connected to the support 12, and the rotating drum 34 is rotatably connected to the upper and lower sides of the support plate 33. The output end of each variable frequency motor 13 is coaxially sleeved with two sprockets 2 14. The chain 2 35 is respectively engaged and sleeved on the outside of the sprocket 2 14 and the rotating drum 34, and the sprocket 2 14 engaged by the chain 2 35 is different from the sprocket 2 14 sleeved by the chain 1 11. A cross slot 36 is provided on the rotating drum 34 to cooperate with the cross key 28.

[0036] A guide rod 30 is connected to the groove body 3, and both ends of the bracket 31 are slidably sleeved on the outer side of the guide rod 30. The brackets 31 on the upper and lower sides are respectively arranged on the side of the upper and lower slide cylinders 26 away from each other. One end of the cross key 28 is limitedly slidably sleeved in the slide cylinder 26, and the other end slides through to the outside of the slide cylinder 26. A spring 29 is connected between one end of the cross key 28 in the slide cylinder 26 and the inner wall of the slide cylinder 26, so that the bracket 31 can slide more stably in the groove body 3.

[0037] A camera can also be installed outside the three-dimensional wound iron core transformer 1 to monitor the dust thickness on the surface of the heat dissipation fin 4 at all times. When the dust reaches a certain thickness, or it rains, the telescopic member 15 is automatically started to drive the folding plate 16 and the air guide plate 17 to move to the side away from the three-dimensional wound iron core transformer 1, so that a distance is generated between the air guide plate 17 and the heat dissipation fin 4, and as the air guide plate 17 moves away, the folding plate 16 will gradually conflict with the dial plate 18, driving the bracket 31 to move away from the slot body 3, and then pushing the rotating plate 1 32 to rotate, so that the upper and lower side sleeves 27 compete with each other, and then the upper and lower side screw rods 20 approach each other. The slide 26 sliding in the limiting circular groove 24 at one end can approach each other under the drive of the sleeve 27, so that the upper and lower side cross keys 28 approach each other to the rotating cylinder 34 on each side, and are inserted into the cross slot 36 opened on the rotating cylinder 34; When the cross key 28 cannot be directly aligned with the cross slot 36, a spring 29 is connected between one end of the cross key 28 sliding in the slide cylinder 26 and its inner wall, so that the spring 29 can be compressed, and the cross key 28 is retracted to one end inside the slide cylinder 26, and the rotating cylinder 34 is driven by the sprocket 14 to rotate through the chain 35, so that the cross slot 36 can be rotated to align with the cross key 28. Then, under the action of the spring 29, the cross key 28 can be inserted into the cross slot 36, and the rotation of the rotating cylinder 34 drives the screw rod 20 to rotate, so that the screw rod 20 is driven back and forth in forward and reverse directions to drive the threaded collar 21 and the frame 22 threaded thereon to move up and down, thereby realizing that the scraper 23 scrapes and cleans the surface of the heat sink 4, ensuring that the surface of the heat sink 4 is not covered with thick dust, which affects the heat dissipation effect.

[0038] Example 4: Figures 1-11 As shown, the present invention discloses a three-dimensional wound core transformer with a heat dissipation structure. Compared with the third embodiment, this embodiment discloses the structure of a self-cleaning component.

[0039] The self-cleaning assembly includes a sleeve frame 37, a slide 39, and a limit frame 42. The sleeve frame 37 is slidably mounted on the outside of the scraper 23. The slide 39 is slidably arranged on the side of the upper and lower side frames 22 away from each other. A rotating plate 2 41 is rotatably connected between each slide 39 and the sleeve frame 37. The limit frame 42 is installed on the upper and lower end surfaces of the three-dimensional wound iron core transformer 1 and cooperates with the slide 39 to interfere with it.

[0040] The frame 22 is connected to a slide frame 38 , both ends of a slide plate 39 are slidably sleeved on the outside of the slide frame 38 , and a spring 2 40 sleeved on the outside of the slide frame 38 is connected between the slide plate 39 and the frame 22 .

[0041] When the upper and lower frames 22 move away from each other and drive the upper and lower scrapers 23 to move away from each other, the slide plate 39 sliding on the frame 22 will conflict with the limit frame 42 on each side, and push the slide plate 39 to slide toward the frame 22, thereby driving the rotating plate 2 41 to rotate, and pushing the sleeve frame 37 to slide on the surface of each scraper 23, so as to clean the scraper 23 and ensure that the scraper 23 can effectively clean the heat dissipating fin 4 each time it contacts the heat dissipating fin 4, thereby improving the cleaning effect and indirectly improving the heat dissipation effect of the heat dissipating fin 4. The dust after cleaning can also be blown away in time by the air pump 6, and will not gather on or near the surface of the three-dimensional wound iron core transformer 1.

[0042] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
