Description

A noise-reducing dry-type transformer Technical Field

[0001] This invention relates to the technical field of dry-type transformers, and in particular to a noise-reducing dry-type transformer. Background Technology

[0002] A dry-type transformer is a type of transformer in which neither the core nor the windings are immersed in an insulating liquid (such as transformer oil). It primarily relies on air, resin, or other solid materials as the insulating medium. Its core characteristic is that it does not require oil cooling, thus offering advantages such as fire resistance, explosion protection, and environmental friendliness, and is widely used in locations with high safety requirements.

[0003] In the existing technology, dry-type transformers are equipped with soundproof enclosures and soundproof panels. The soundproof panels inside the soundproof enclosure can block the transmission of noise and reduce noise along the noise propagation path generated by the transformer body, thereby effectively reducing the transmission of noise and thus reducing the impact on the daily lives of surrounding residents.

[0004] However, in actual use, it is necessary to cover the transformer with a soundproof cover and soundproof board, and then fix the soundproof cover and soundproof board. This is not only more troublesome to operate, but also reduces the installation efficiency of the pole transformer. In addition, it is inconvenient to transport due to its large overall space occupation. Therefore, there are areas for improvement. Summary of the Invention

[0038] The second flipping structure includes a second fixing plate 24 connected to the two end corners of the vertical plate 3. The two second fixing plates 24 rotate through the second rotating rod 25. The top plate 26 is fixedly sleeved on the second rotating rod 25. A second groove 46 is opened in the middle of the side of the top plate 26 near the second rotating rod 25. A first driving structure is provided between the second rotating rod 25 and the T-shaped plate 7.

[0039] The first driving structure includes a second gear 27 fixedly sleeved on the middle of the second rotating rod 25, a first vertical groove 29 opened on the vertical plate 3, a lifting block 30 slidably arranged in the first vertical groove 29, a pull plate 31 installed on the lifting block 30, a pull groove 33 opened on the pull plate 31, a first driving plate 28 connected to the middle of the upper part of the lifting block 30, the second gear 27 sleeved on the middle of the second rotating rod 25, teeth provided on the first driving plate 28 that mesh with the second gear 27, and a pull rod 32 connected to the middle of the T-shaped plate 7, one end of the pull rod 32 being movably inserted into the pull groove 33;

[0040] The third flipping structure includes a third fixing plate 34 connected to two corners on one side of the top plate 26. The two third fixing plates 34 rotate through a third rotating rod 35. A flipping plate 36 is fixedly sleeved on the third rotating rod 35. A second driving structure is provided between the flipping plate 36 and the vertical plate 3. A splicing groove is provided on the flipping plate 36.

[0041] The second driving structure includes a second vertical groove 39 formed on the top plate 26, a second driving plate 40 slidably disposed in the second vertical groove 39, a first groove 37 formed in the middle of one side of the flip plate 36, a third gear 38 fixedly sleeved on the middle of the third rotating rod 35, teeth on the flip plate 36 that mesh with the third gear 38, two fixed plates 42 fixedly disposed on the vertical plate 3, a through hole for the second rotating rod 25 to move through the center of the fixed plate 42, an L-shaped rod 41 connected to one end of the second driving plate 40, a first arc groove 43 formed on the fixed plate 42, and a first arc groove 43 formed on the fixed plate 42. There is a connecting groove 44 that connects to the first arc-shaped groove 43. A second arc-shaped groove 45 that connects to one end of the connecting groove 44 is opened on the fixed plate 42. One end of the L-shaped rod 41 is movably inserted into the first arc-shaped groove 43. When performing noise reduction work on the transformer body 2, the motor 12 on the fixed base 11 is started to drive the two screws 13 to rotate. The two moving blocks 15 move synchronously in opposite directions on the two rotating screws 13, thereby driving the T-shaped plate 7 to move. Through the connecting plate 8, the two moving plates 5 move synchronously in opposite directions. During the movement of the T-shaped plate 7, one end of the pull rod 32 moves on the pull plate. The upper sliding plate 31 slides in the upper sliding groove 33. Using the pressure of one end of the sliding rod 32 against the groove wall of the sliding groove 33, the lifting block 30 and the sliding plate 31 move downwards in the first vertical groove 29. This, through the first driving plate 28 and the second gear 27, drives the second rotating rod 25 to rotate, thereby rotating the top plate 26 on the vertical plate 3. During the rotation of the top plate 26, one end of the L-shaped rod 41 slides from the first arc-shaped groove 43 and the connecting groove 44 to the second arc-shaped groove 45. Thus, the L-shaped rod 41 pulls the second driving plate 40 to slide in the second vertical groove 39. Through the third gear 38, the top plate 26 rotates and flips. In the process of rotating plate 36, the moving plate 5 drives the side plate 4 to move to the two sides of the vertical plate 3, and the first insert rod 19 slides in the first driving groove 20, driving the insert plate 18 to move in the slot 17. Through the L-shaped strip 21 and the first gear 22, the side plate 4 is automatically rotated and pressed against the fixed edge 23. Then the flipped top plate 26 drives the splicing groove on the flipped plate 36 to the splicing strip on the side plate 4. In this way, the unfolded vertical plate 3, side plate 4, top plate 26 and flipped plate 36 are used to cover the outside of the transformer body 2 to play a role in noise reduction. The structure is simple and the function is practical.

[0042] Referring to Figure 1, the heat dissipation structure includes an air outlet slot in the middle of the base 1, and air inlet slots 47 on both the front and rear sides of the base 1. Fans are installed in both the air outlet slots and the air inlet slots 47. Dustproof nets 10 are installed on the walls of both the air inlet slots 47 and the air outlet slots. When the transformer body 2 is working, the fans are turned on. The rotation of the fan in the air inlet slot 47 draws in outside air, and the rotation of the fan in the air outlet slot dissipates heat. In this way, the flow of air can better dissipate the heat generated by the transformer body 2 during operation, resulting in a higher heat dissipation effect.

[0043] Referring to Figures 1-3, the installation structure includes a mounting groove 48 formed on the rear edge of the base 1. A mounting plate 49 is movably inserted into the mounting groove 48. The mounting plate 49 is fixedly set under the base plate 16. Slots 50 are formed on both the left and right ends of the mounting plate 49. Inner grooves 52 are formed on both the left and right sides of the mounting groove 48 within the base 1. A locking rod 53 is movably inserted into the inner groove 52. A pull ring 55 is installed at one end of the locking rod 53 extending out of the base 1. A locking plate 51 is provided at the other end of the locking rod 53. One end of the locking plate 51 is movably inserted into the slot 50. The locking plate 51 movably passes through the groove wall of the inner groove 52. A spring 54 is fitted onto the base 53. The two ends of the spring 54 are connected to the retaining plate 51 and one end of the groove wall of the inner groove 52, respectively. When the mounting plate 49 is inserted into the mounting groove 48 on the base 1, the two ends of the mounting plate 49 first press against the inclined surface of one end of the retaining plate 51, pushing the retaining plate 51 to move and causing the spring 54 to deform. When the mounting plate 49 is fully inserted into the mounting groove 48, under the elastic force of the spring 54, the retaining plate 51 is pushed into the retaining groove 50 on the mounting plate 49. In this way, the vertical plate 3 can be installed on the base 1. The operation is simple and convenient, and it is also easy to disassemble and reuse.

[0044] The implementation principle of a noise-reducing dry-type transformer according to an embodiment of the present invention is as follows: When reducing noise on the transformer body 2 during operation on the base 1, when the mounting plate 49 is inserted into the mounting groove 48 on the base 1, the two ends of the mounting plate 49 first press against the inclined surface of one end of the clamping plate 51, pushing the clamping plate 51 to move and causing the spring 54 to deform. When the mounting plate 49 is fully inserted into the mounting groove 48, under the elastic force of the spring 54, the clamping plate 51 is pushed into the clamping groove 50 on the mounting plate 49. The vertical plate on the base 1... 3. Install the device, then start the motor 12 on the fixed base 11 to drive the two screws 13 to rotate. The two moving blocks 15 move synchronously in opposite directions on the two rotating screws 13, thereby driving the T-shaped plate 7 to move. Through the connecting plate 8, the two moving plates 5 move synchronously in opposite directions. During the movement of the T-shaped plate 7, one end of the pull rod 32 slides in the pull groove 33 on the pull plate 31. By using the pressure of one end of the pull rod 32 against the groove wall of the pull groove 33, the lifting block 30 and the pull plate 3 are pulled. 1. The entire assembly moves downward in the first vertical groove 29, driving the second rotating rod 25 to rotate via the first driving plate 28 and the second gear 27, thereby rotating the top plate 26 on the vertical plate 3. During the rotation of the top plate 26, one end of the L-shaped rod 41 slides from the first arc-shaped groove 43 and the connecting groove 44 to the second arc-shaped groove 45. In this way, the L-shaped rod 41 pulls the second driving plate 40 to slide in the second vertical groove 39, and via the third gear 38, the flip plate 36 rotates on the top plate 26. During this process, the moving plate 5 drives the side... Plate 4 moves to the two sides of the vertical plate 3 and slides in the first drive groove 20 using the first insert rod 19, causing the insert plate 18 to move in the slot 17. Through the L-shaped strip 21 and the first gear 22, the side plate 4 is automatically rotated and pressed against the fixed edge 23. Then, the flipped top plate 26 drives the splicing groove on the flipped plate 36 to the splicing strip on the side plate 4. In this way, the unfolded vertical plate 3, side plate 4, top plate 26 and flipped plate 36 are used to cover the outside of the transformer body 2 to achieve the effect of noise reduction.

[0045] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
