Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, and in particular to a pad for a dry-type transformer. Background Technology

[0002] As society becomes increasingly industrialized and people's living standards improve, the demand for electricity is also growing. This necessitates a large number of transformers to address power supply issues. Dry-type transformers are widely used in high-rise buildings, airports, railways, rail transit, docks, and CNC machinery equipment, thus improving people's living standards. Spacers are insulating components in dry-type transformers that bear, compress, and position the voltage coil assembly (which includes the high-voltage coil, low-voltage coil, and insulating cylinder).

[0003] Patent document CN211879201U discloses a pad for a dry-type transformer, including a body. At least one raised ring is provided on the side of the body, with the raised rings spaced apart from top to bottom. A U-shaped groove with an opening facing downwards is provided on the lower side of the body. The body is made of insulating material. When the pad is installed between the clamps and the coil housing of the dry-type transformer, the creepage distance of the coil terminals is increased by the raised ring portion of the pad, thus extending the creepage distance of the coil terminals. This reduces the phenomenon of transformer coil burnout, reduces transformer damage, and lowers costs. Moreover, compared to increasing the height of the pad, this application does not require increasing the height; only the raised rings need to be added, which also saves costs.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing pads are not convenient to adjust according to dry-type transformers of different widths, and the height is not convenient to adjust. Therefore, a pad for dry-type transformers is designed to provide another technical solution to the above technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a pad for dry-type transformers to address the above-mentioned technical problems, which is that existing pads are not convenient to adjust according to dry-type transformers of different widths, and are also inconvenient to adjust in height.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A pad for a dry-type transformer includes a first pad, with clamps slidably connected to both ends of the top of the first pad. Anti-shifting components for limiting the clamps are installed on both sides of the first pad. A third pad is slidably connected to the bottom of the first pad. The anti-shifting components include anti-shifting blocks and fastening bolts. Sliding grooves are provided inside both sides of the first pad at positions corresponding to the clamps. Anti-shifting blocks are provided on both sides of the first pad at positions corresponding to the clamps. The anti-shifting blocks are slidably connected to the first pad. Fastening bolts are detachably connected inside the anti-shifting blocks. The tail end of the fastening bolt passes through the sliding groove and is threadedly connected to the clamp.

[0008] In a preferred embodiment of the pad block for a dry-type transformer provided by this utility model, a second pad is further provided between the first pad and the third pad.

[0009] In a preferred embodiment of the pad block for a dry-type transformer provided by this utility model, first protrusions are evenly distributed and fixed at the bottom of the first pad and the second pad, and second protrusions are evenly distributed and fixed at the top of the second pad and the third pad, with the first protrusions and the second protrusions being fixed alternately.

[0010] In a preferred embodiment of the pad block for a dry-type transformer provided by this utility model, positioning grooves are evenly distributed inside the first pad plate and at the top and bottom of the sliding groove, and the anti-displacement block is slidably connected to the first pad plate through the positioning grooves.

[0011] In a preferred embodiment of the pad block for a dry-type transformer provided by this utility model, a positioning mechanism for connection is installed between the two ends of the first pad and the second pad, and between the two ends of the second pad and the third pad. The positioning mechanism includes an assembly plate, an assembly column, and a positioning bolt. The top and bottom of the assembly plate are fixed with assembly columns, and the positioning bolts are slidably connected inside the assembly columns. One of the assembly columns has a pressing slope on the top of the end away from the assembly plate.

[0012] In a preferred embodiment of the pad block for a dry-type transformer provided by this utility model, assembly cavities are provided inside the bottom ends of the first and second pads, and inside the top ends of the second and third pads. Each assembly cavity includes a first assembly groove, a second assembly groove, a third assembly groove, and a fourth assembly groove. A third assembly groove is provided inside the first, second, and third pads, and the third assembly groove is slidably connected to the assembly plate. A first assembly groove and a second assembly groove are respectively provided inside the first, second, and third pads at both ends of the clamping plate. The first assembly groove is slidably connected to the assembly column, and the second assembly groove is slidably connected to the assembly column. A fourth assembly groove is provided inside the first, second, and third pads at positions corresponding to the first and second assembly grooves, and the fourth assembly groove is slidably connected to the assembly plate.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Reference Figures 1-7 A pad for a dry-type transformer includes a first pad 1. Both ends of the top of the first pad 1 are slidably connected to clamps 4, so that the distance can be adjusted by bringing the two clamps 4 closer to each other, thereby allowing dry-type transformers of different widths to be assembled on the top of the first pad 1 between the two clamps 4. Anti-movement components for limiting the clamps 4 are installed on both sides of the first pad 1. A third pad 3 is slidably connected to the bottom of the first pad 1, so that the bottom of the first pad 1 can be supported by the third pad 3.

[0032] In this embodiment, the dry-type transformer is an existing device, and its specific model is not set, as long as its width is within the maximum dimension between the two clamping plates 4.

[0033] Preferably, a cushioning pad, such as a sponge or other elastic material coated with an insulating material, can be fixed between the two clamps 4.

[0034] Preferably, a second pad 2 is provided between the first pad 1 and the third pad 3, so that different numbers of second pads 2 can be added as needed to adjust the top height of the first pad 1.

[0035] Preferably, the bottom of the first pad 1 and the second pad 2 are both evenly fixed with first protrusions 9, and the top of the second pad 2 and the third pad 3 are both evenly fixed with second protrusions 10. The first protrusions 9 and the second protrusions 10 are fixed in an alternating manner, so that when the third pad 3 is assembled at the bottom of the first pad 1, the first pad 1 and the third pad 3 can only be separated by lifting and lowering due to the alternation of the first protrusions 9 and the second protrusions 10. Similarly, the assembly between the first pad 1 and the second pad 2, and between the second pad 2 and the third pad 3, is also achieved by sliding the corresponding first protrusions 9 and the second protrusions 10 together, and can only be separated by lifting and lowering.

[0036] The anti-shifting assembly includes anti-shifting blocks 7 and fastening bolts 8. Sliding grooves 5 are provided on both sides of the first pad 1 at positions corresponding to the clamping plate 4, with the top of the sliding grooves 5 being lower than the top plane of the first pad 1. The two sliding grooves 5 are symmetrically provided at the same end. Anti-shifting blocks 7 are provided on both sides of the first pad 1 at positions corresponding to the clamping plate 4. The anti-shifting blocks 7 are concave in shape and are slidably connected to the first pad 1. Fastening bolts 8 are detachably connected inside the anti-shifting blocks 7. Specifically, the fastening bolts 8 are slidably connected inside the anti-shifting blocks 7, allowing the fastening bolts 8 to slide into and out of the anti-shifting blocks 7. The tail end of the fastening bolts 8 passes through the sliding grooves 5 and is threadedly connected to the clamping plate 4. When the anti-shifting blocks 7 are located inside the first pad 1, the fastening bolts 8 and the threaded connection between the fastening bolts 8 and the clamping plate 4 position the clamping plate 4 inside the first pad 1.

[0037] Preferably, the first pad 1 has positioning grooves 6 evenly distributed inside the sliding groove 5 at the top and bottom. The anti-displacement block 7 is slidably connected to the first pad 1 through the positioning grooves 6, so that the anti-displacement block 7 can be positioned by translation through the positioning grooves 6.

[0038] Positioning mechanisms 11 for connection are installed between the two ends of the first pad 1 and the second pad 2, and between the two ends of the second pad 2 and the third pad 3. The positioning mechanism 11 includes an assembly plate 16, an assembly column 17, and a positioning bolt 18. The assembly column 17 is fixed at the top and bottom of the assembly plate 16. The positioning bolt 18 is slidably connected inside the assembly column 17, so that the positioning bolt 18 can pass through the assembly column 17 and be threadedly connected to the corresponding first pad 1, second pad 2, or third pad 3 to fix the position of the assembly column 17. One of the assembly columns 17 has a pressing slope 19 on the top of the end away from the assembly plate 16. This allows the other assembly column 17 to be located inside the first pad 1, or to enter the second pad 2 or third pad 3, through the pressing slope 19 on one of the assembly columns 17, so that when the other assembly column 17 is inside the first pad 1, or when the other assembly column 17 enters the second pad 2 or third pad 3, it can be pressed quickly into place and positioned through the pressing slope 19 on the other assembly column 17.

[0039] Assembly cavities are provided inside the bottom ends of the first pad 1 and the second pad 2, and inside the top ends of the second pad 2 and the third pad 3. Each assembly cavity includes a first assembly groove 12, a second assembly groove 13, a third assembly groove 14, and a fourth assembly groove 15. A third assembly groove 14 is provided inside the first pad 1, the second pad 2, and the third pad 3, and is slidably connected to the assembly plate 16. The first assembly groove 12 and the second assembly groove 13 are respectively provided inside the first pad 1, the second pad 2, and the third pad 3 at both ends of the clamping plate 4. The first assembly groove 12 and the assembly column 17 are slidably connected, as are the second assembly groove 13 and the assembly column 17, so that the first assembly groove 12 and the second assembly groove 13 are both connected through the third assembly groove 14. The first pad 1, the second pad 2 and the third pad 3 are each provided with a fourth assembly groove 15 at a position corresponding to the first assembly groove 12 and the second assembly groove 13. The fourth assembly groove 15 is slidably connected to the assembly plate 16, so that the assembly plate 16 can move from the inside of the third assembly groove 14 to the inside of the fourth assembly groove 15 after rotation.

[0040] In this embodiment, the second pad 2 can be one or more, or zero.

[0041] In this embodiment, the two ends of the third pad 3 can also be fixed with ear plates with through holes for fixing to the ground by bolts.

[0042] The usage process of the pad block for a dry-type transformer provided by this utility model is as follows: During use, select different numbers of second pads 2 according to the required height of the dry-type transformer. Then, assemble the second pads 2 onto the top of the third pad 3 through the cooperation of the corresponding first protrusion 9 and second protrusion 10. Then, assemble the first pad 1 onto the top of the second pad 2 through the cooperation of the corresponding first protrusion 9 and second protrusion 10. At this time, rotate the positioning bolt 18 in the positioning mechanism 11, so that the positioning bolt 18 extends after rotating through the threaded connection with the first pad 1 or the second pad 2, thereby allowing the mounting column 17 to slide away from the corresponding first pad 1 or second pad 2 on the outside of the positioning bolt 18. Then, the positioning bolt 17... Positioning mechanism 11 rotates 90 degrees around positioning bolt 18, so that assembly plate 16 is located inside the fourth assembly groove 15. At the same time, the remaining assembly pillars 17 of the first pad 1 enter the corresponding second pad 2, and the remaining assembly pillars 17 of the second pad 2 enter the corresponding third pad 3. With the assistance of the pressing inclined surface 19, positioning bolt 18 is rotated in the opposite direction, so that the fixing of positioning bolt 18 presses the outer assembly pillars 17 back into the first pad 1 or the second pad 2, so that assembly plate 16 is completely located inside the fourth assembly groove 15. At this time, the first pad 1 cannot be dislodged from the top of the second pad 2 by rising, and the third pad 3 cannot be dislodged from the bottom of the second pad 2 by falling.

[0043] Then, the dry-type transformer is placed between the two clamping plates 4 on the top of the first pad 1. At this time, the clamping plates 4 are slid to make contact with the outside of the dry-type transformer. Then, the anti-shifting block 7 is moved closer to the first pad 1 by sliding on the outside of the fastening bolt 8, so that the anti-shifting block 7 enters the corresponding positioning groove 6. Then, the fastening bolt 8 is rotated to limit the anti-shifting block 7. At this time, the clamping plate 4 cannot be moved.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
