TECHNICAL FIELD

[0001] The present application relates to the field of three-dimensional winding core transformer, and particularly relates to a three-dimensional winding core transformer with a heat dissipation structure. BACKGROUND

[0002] The three-dimensional winding core transformer is a kind of transformer which realizes high efficiency and energy saving through innovation of core structure, and the core feature is that a three-phase integrated three-dimensional winding core is adopted, which has significant advantages in magnetic circuit design, loss control, noise suppression and the like compared with a traditional lamination core (three-phase separate lamination).

[0003] No matter the three-dimensional winding core transformer or the traditional transformer, optimizing the heat dissipation performance of the transformer can effectively improve the energy efficiency. During operation of the transformer, heat is generated due to core loss (magnetic hysteresis loss and eddy current loss) and winding loss (resistance loss), and if the heat cannot be dissipated in time, the internal temperature of the transformer will rise, which will have a negative impact on the energy efficiency, service life and safety of the transformer.

[0004] However, the heat dissipation of the existing three-dimensional winding core transformer mainly relies on the natural heat dissipation of the externally installed heat dissipation fins, and when the three-dimensional winding core transformer generates a large amount of heat, especially in high-temperature weather in summer, the heat dissipation efficiency will be seriously reduced, and at the same time, the use safety will also be affected. Easy to failure, damage and cause the failure of power supply of the power grid.

The problem that the optical fiber ultrasonic sensor and the very high frequency sensor need to be implanted in the transformer is effectively solved, and through the combination of the optical fiber ultrasonic sensor and the very high frequency sensor in structure, joint detection of two kinds of signals can be provided, the effectiveness and accuracy of partial discharge detection are improved, and the laying problem of the very high frequency sensor lead-out wire and the optical fiber lead-out wire is solved.

Figures 1-11 ​The application discloses a three-dimensional roll core transformer with a heat dissipation structure.

[0051] The linkage assembly comprises a push plate 18, a limiting circular groove 24, a sliding channel 25, a sliding cylinder 26, a sleeve base 27, a cross-shaped key 28, a support 31 and a rotating plate one 32, the push plate 18 is connected to the upper and lower sides of each folding plate 16, the limiting circular groove 24 is arranged at the end, where the upper and lower sides of the lead screw 20 are close to each other, the sliding channel 25 is arranged on the side surface of the end, where the upper and lower sides of the lead screw 20 are close to each other, and penetrates through the limiting circular groove 24, the sliding cylinder 26 is slidably sleeved in the limiting circular groove 24, and the sliding cylinder 26 extends outside the lead screw 20 through the sliding channel 25, the sleeve base 27 is rotatably sleeved outside the extension end of the sliding cylinder 26 outside the lead screw 20, the cross-shaped key 28 is slidably arranged in the sliding cylinder 26, and one end of the cross-shaped key 28 extends between the ends, where the upper and lower sides of the lead screw 20 are close to each other, through the sliding cylinder 26 and the limiting circular groove 24, the support 31 is slidably arranged in the groove body 3, and the rotating plate one 32 is rotatably connected between the support 31 and the sleeve base 27, the push plate 18 is in abutment with the support 31, the support 12 is provided with a synchronous assembly, and the synchronous assembly is used for being inserted in cooperation with the cross-shaped key 28.

[0052] The synchronous assembly comprises a support plate 33, a rotating cylinder 34 and a chain two 35, the support plate 33 is connected to the support 12, the rotating cylinder 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 chain wheels two 14, the chain two 35 is sleeved on the outside of the chain wheel two 14 and the rotating cylinder 34 respectively, and the chain wheel two 14 sleeved by the chain two 35 is different from the chain wheel two 14 sleeved by the chain one 11, and the rotating cylinder 34 is provided with a cross-shaped slot 36, which is used for being inserted in cooperation with the cross-shaped key 28.

[0053] The groove body 3 is connected with a guide rod 30, the two ends of the support 31 are slidably sleeved on the outer side surface of the guide rod 30, the upper and lower supports 31 are arranged on the sides, where the upper and lower sliding cylinders 26 are away from each other, one end of the cross-shaped key 28 is slidably sleeved in the sliding cylinder 26, and the other end is slidably penetrated out of the sliding cylinder 26, and the one end of the cross-shaped key 28 in the sliding cylinder 26 is connected with the inner wall of the sliding cylinder 26 through a spring one 29, so that the support 31 can slide more stably in the groove body 3.

[0054] A camera can also be installed on the outside of the three-dimensional wound core transformer 1 to monitor the thickness of dust on the surface of the heat dissipation fins 4 at all times. When the dust reaches a certain thickness, or on a rainy day, the telescopic component 15 will be automatically activated to drive the folding plate 16 and the air guide plate 17 to move away from the three-dimensional wound core transformer 1. This will create a gap between the air guide plate 17 and the heat dissipation fins 4. As the air guide plate 17 moves away, the folding plate 16 will gradually come into contact with the lever plate 18, causing the bracket 31 to move away from the slot 3. This will then push the rotating plate 32 to rotate, causing the upper and lower sleeves 27 to compete with each other. As a result, the upper and lower screws 20 will move closer to each other. The sliding cylinder 26 that slides in the limiting circular groove 24 at one end can move closer to each other under the action of the sleeve 27. This will cause the upper and lower cross key 28 to move closer to each other to the rotating cylinder 34 on their respective sides and be inserted into the cross slot 36 opened on the rotating cylinder 34.

[0055] When the cross key 28 and the cross slot 36 cannot be directly aligned and inserted, a spring 29 is connected between the sliding end of the cross key 28 inside the slide cylinder 26 and its inner wall. This spring 29 can be compressed, causing the cross key 28 to retract into one end of the slide cylinder 26. The rotating cylinder 34 is driven to rotate by the sprocket 14 via the chain 35, allowing the cross slot 36 to rotate until it is aligned 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. The rotation of the rotating cylinder 34 drives the lead screw 20 to rotate, achieving reciprocating forward and reverse rotation of the lead screw 20. This drives the threaded collar 21 and the frame 22 on the lead screw 20 to move up and down, thereby enabling the scraper 23 to scrape and clean the surface of the heat dissipation fins 4, ensuring that the surface of the heat dissipation fins 4 is not covered with a thick layer of dust, which would affect the heat dissipation effect.

[0056] Example 4: Figures 1-11 As shown, the present invention discloses a three-dimensional wound core transformer with a heat dissipation structure. Compared with Embodiment 3, this embodiment discloses the structure of a self-cleaning component.

[0057] The self-cleaning component includes a frame 37, a slide plate 39, and a limiting bracket 42. The frame 37 is slidably fitted on the outside of the scraper 23. The slide plate 39 is slidably set on the upper and lower frame bodies 22, which are far apart from each other. Each slide plate 39 is rotatably connected to the frame 37 by a rotating plate 41. The limiting bracket 42 is installed on the upper and lower end faces of the three-dimensional wound iron core transformer 1 and cooperates with the slide plate 39 to abut.

[0058] A slide bar frame 38 is connected to the frame 22. Both ends of the slide plate 39 are slidably sleeved on the outside of the slide bar frame 38. A spring 40 sleeved on the outside of the slide bar frame 38 connects the slide plate 39 and the frame 22.

[0059] When the upper and lower frame bodies 22 are moved away from each other and drive the upper and lower scraping plates 23 to move away from each other, the sliding plate 39 slidingly arranged on the frame body 22 will be in contact with the limiting frame 42 on the respective side, and push the sliding plate 39 to slide towards the frame body 22, thereby driving the rotating plate 41 to rotate, pushing the sleeve frame 37 to slide on the surface of each scraping plate 23, realizing the cleaning of the scraping plate 23, ensuring that the scraping plate 23 can effectively clean the heat dissipation fins 4 when it contacts the heat dissipation fins 4 each time, thereby improving the cleaning effect and indirectly improving the heat dissipation effect of the heat dissipation fins 4, and the dust cleaned can be blown away in time by the air pump 6 and will not accumulate on the surface or near the surface of the three-dimensional roll core transformer 1.

[0060] According to the disclosure and teaching of the above description, those skilled in the art of the present application can also make changes and modifications to the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should fall within the protection scope of the claims of the present application.
