Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer used in a high-voltage power grid. Background Art

[0002] Transformers, as crucial electrical equipment in high-voltage power grids, undertake the critical tasks of changing voltage levels and transmitting and distributing electrical energy. However, current transformer wiring still relies on manual tools such as screwdrivers and wrenches to tighten and remove screws. Workers need to use tools to tighten nuts or bolts to secure cables and terminal blocks. During new equipment installations or high-voltage power grid expansions, operators must mechanically tighten hundreds of terminal blocks one by one. Wiring a single transformer can take hours, and this primitive operation method can extend the high-voltage power grid construction cycle.

[0003] To this end, a transformer for a high-voltage power grid is proposed. Summary of the Invention

[0004] The object of the present invention is to provide a transformer for a high voltage power grid to solve the problems raised in the above background technology.

[0006] Furthermore, a stabilizing component is also provided, which includes a carrying plate, and the supporting plate is symmetrically fixedly connected to two carrying plates in the middle of one side away from the terminal post, each carrying plate is provided with a guide groove 2, and a slider is slidably connected inside the two guide grooves 2, and the top of the two sliders is fixedly connected to a connecting column, and the top of the two connecting columns is fixedly connected to a rubber arc block, and a three-section telescopic rod is fixedly connected between the sides close to the two connecting columns, and the three-section telescopic rod includes two telescopic shafts and a fixed shaft, the two telescopic shafts are slidably connected to the fixed shaft, and the two telescopic shafts are respectively fixedly connected to the two connecting columns, and a gear is connected to the bottom of the two carrying plates for common rotation, and an upper gear rod is fixedly connected to the side of the top pressure plate close to the carrying plate, and a lower gear rod is slidably connected to the supporting plate, and one end of the lower gear rod close to the three-section telescopic rod is fixedly connected to the fixed shaft of the three-section telescopic rod, and the lower gear rod and the upper gear rod are both meshed with the gear.

[0007] Furthermore, the top end of the guide shaft passes through the bottom pressure plate, and the two ends of the spring are fixedly connected to the bottom surface of the bottom pressure plate and the adjacent bottom end of the guide shaft respectively.

[0008] Furthermore, the top pressure plate is made of rubber material.

[0009] Furthermore, four guide shafts are slidably connected to the bottom pressure plate, and the top ends of the four guide shafts are fixedly connected to a top pressure plate.

[0010] Furthermore, the rubber arc block is provided with an anti-slip texture.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Operators can quickly install and remove cables and transformers by simply pressing the slot plate. Compared with traditional tool-based tightening and removal, this can significantly reduce the time required to connect and disconnect cables and terminal blocks, shortening the time required for wiring installation. This can speed up the wiring progress of the entire power grid when installing new transformers or expanding high-voltage power grids.

[0013] By using two rubber arc blocks to clamp the cable and apply pressure toward the terminal during cable installation, the conductive contact between the cable and the bottom pressure plate can be made closer, effectively preventing loose connections caused by vibration, thermal expansion and contraction, etc., ensuring that the cable and the terminal always maintain a good electrical connection during transformer operation, reducing faults caused by poor contact;

[0014] The cable is clamped and limited by two rubber arc blocks, making the conductive contact between the cable and the terminal closer. The close contact increases the contact area for current transmission, thereby reducing contact resistance, reducing energy loss during power transmission, improving power transmission efficiency, reducing heat generation at the connection part, and ensuring the stable operation of the high-voltage power grid system;

[0015] When removing the cable from the terminal, the two rubber arc blocks pull the cable a distance away from the terminal. At the same time, the two rubber arc blocks move away from each other until they no longer interfere with the cable, quickly separating the conductive contact between the cable and the terminal. During transformer operation, the connection between the bare wire end of the cable and the bottom pressure plate may become slightly adhered due to heat or other reasons. In this case, there is no need to manually pull the cable from the bottom pressure plate, which greatly saves disassembly time and improves the convenience of connecting and removing the wiring.

[0016] The spring, three-section telescopic rod, gear and other structures are located inside the insulating sleeve and will not stick to the insulating sealing filler of the sealing sleeve, which can reduce the difficulty of cleaning during disassembly and shorten the time required for line replacement.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention provides the following embodiments:

[0033] Example 1: Please refer to Figures 1 to 6 As shown, a transformer for a high-voltage power grid includes a transformer 11 and multiple high-voltage bushings 12 and multiple low-voltage bushings 13. The multiple high-voltage bushings 12 and multiple low-voltage bushings 13 are all installed on the top of the transformer 11. A terminal 14 is installed on the top of each high-voltage bushing 12 and low-voltage bushing 13. The terminal 14 is used to connect to a cable 15.

[0034] The cable 15 is divided into two parts during installation, one of which is a bare wire end connected to the terminal 14 without the protective shell, and the other is a shelled end other than the bare wire end.

[0035] During the wiring process, the wiring process of the high-voltage bushing 12 and the low-voltage bushing 13 is the same.

[0036] The terminal 14 is provided with a quick-release assembly, which includes a terminal plate 21. The terminal plate 21 is mounted on the terminal 14 by bolts and nuts. The terminal plate 21 is fixedly connected to a bottom pressure plate 22 at one end away from the terminal 14. A plurality of guide shafts 23 are slidably connected to the bottom pressure plate 22. The top ends of the guide shafts 23 pass through the bottom pressure plate 22. The top ends of the plurality of guide shafts 23 are fixedly connected to a top pressure plate 24. A spring 25 is provided on each of the plurality of guide shafts 23. The two ends of the spring 25 are respectively fixedly connected to the bottom surface of the bottom pressure plate 22 and the bottom end of the adjacent guide shaft 23. The top of the top pressure plate 24 close to the terminal plate 21 is fixedly connected to a slot plate 26. A guide groove 27 is provided on the side of the slot plate 26 close to the terminal block 21, and a sliding column 28 is slidably connected inside the guide groove 27. An end of the sliding column 28 away from the guide groove 27 is fixedly connected to an elastic rod 29. A support block 210 is fixedly connected to the top of the terminal block 21 close to the top pressure plate 24. The top of the support block 210 is rotatably connected to a rotating shaft 211. A torsion spring 212 is sleeved on the rotating shaft 211. The two ends of the torsion spring 212 are respectively fixedly connected to the support block 210 and the rotating shaft 211. The bottom end of the elastic rod 29 is fixedly connected to the end of the rotating shaft 211 close to the slot plate 26. An insulating sleeve is sleeved on the outside of each high-voltage bushing 12 and the low-voltage bushing 13.

[0037] Among them: reference Figure 2 、 Figure 3 and Figure 7 As shown, the middle portions of the bottom pressing plate 22 and the top pressing plate 24 are both configured to be relatively arched, and their function is to match the circular shape of the bare wire end of the cable 15 .

[0038] Specifically: There is no restriction on the size of the arch of the bottom pressure plate 22 and the top pressure plate 24, that is, it is determined according to the size of the bare wire end of the cable 15 to be connected, ensuring that the bottom pressure plate 22 and the top pressure plate 24 can fit and contact with the bare wire end of the cable 15, that is, ensuring that the quick-release and quick-install components can adapt to cables 15 of different sizes and high and low voltage ends.

[0039] A support plate 31 is fixedly connected to the bottom of the bottom pressure plate 22 away from the terminal 14 , and the bottom end of the support plate 31 is detachably connected to the top of the transformer 11 by bolts.

[0040] Among them: the top pressure plate 24 is set to rubber material, the bottom pressure plate 22 is set to metal material, the bottom pressure plate 22 is conductive with the terminal 14 through the terminal plate 21, that is, when the bare wire end of the cable 15 is in contact with the top surface of the bottom pressure plate 22, the bottom pressure plate 22 is used as the conductive part.

[0041] Among them: reference Figure 6 As shown, and Figure 6For position reference, the guide groove 1 27 is divided into: V-shaped groove a at the top middle position, oblique groove 1 b at the top left, oblique groove 2 c at the bottom left, groove point d at the bottom middle position, oblique groove 3 e at the bottom right, and oblique groove 4 f at the top right;

[0042] Specifically, there is a height difference inside the inclined groove 2 c, that is, the depth of the inclined groove 2 c is greater at the end close to the inclined groove 1 b, and the depth of the inclined groove 2 c is smaller at the end close to the groove point d. The function is that when the sliding post 28 slides to the groove point d, it can only slide along the inclined groove 3 e.

[0043] Among them: the elastic rod 29 is set to a hard rubber material, and the top end of the elastic rod 29 can be slightly tilted and deformed toward the side close to the terminal 14 compared to the bottom end. Under the elastic reset action of the elastic rod 29, it is ensured that the limiting slide column 28 always rests inside the guide groove 27.

[0044] Among them: reference Figure 4 、 Figure 6 As shown, the torsion spring 212 is in a state of contraction under force, so the rotating shaft 211 drives the sliding column 28 through the elastic rod 29 to have a tendency to deflect toward the side close to the inclined groove b.

[0045] It should be noted that: in actual use, if Figure 1 As shown, the transformer 11 is provided with a plurality of insulating sleeves (for the convenience of showing the structure in the figure, only Figure 1 (Partially shown in the figure), multiple insulating bushings are respectively sleeved on the multiple high-voltage bushings 12 and the multiple low-voltage bushings 13, as well as the outside of the quick-release and quick-install components provided on the high-voltage bushings 12 and the low-voltage bushings 13, and the shell end portion of the cable 15 can be sleeved therein, providing insulation treatment for the normal operation of the high-voltage bushings 12, the low-voltage bushings 13 and the quick-release and quick-install components thereon, thereby preventing the external environment such as rain, snow, and impurities from affecting the operation of the transformer 11.

[0046] It should be noted that the insulating sleeve is made up of two symmetrical side tubes, and there is a groove for accommodating insulating sealing fillers at the annular seam joint of the two side tubes. In actual use, the operator only needs to seal and fill the grooves at the annular seam joint of the insulating sleeve and the connection between the insulating sleeve and the shell end of the cable 15, and the insulating sleeve and the transformer 11. It is not necessary to fill the entire cavity of the insulating sleeve to avoid the spring 25, the three-section telescopic rod 37, the gear 38 and other structures located in the insulating sleeve cavity from being stuck with fillers and difficult to clean.

[0047] When the quick-release assembly is used, there are two stages of use. The first stage is when the cable 15 is already connected to the terminal 14. At this time, maintenance operations need to be performed on the transformer 11 or the cable 15, and the connection between the cable 15 and the terminal 14 needs to be released.

[0048] At this time, the quick-release and quick-install components are as follows Figures 1 to 6 The usage state is specifically as follows: the top pressure plate 24 and the bottom pressure plate 22 are in contact with each other, the groove plate 26 cooperates with the limiting slide 28 to limit the position of the top pressure plate 24, and the rubber material of the top pressure plate 24 is squeezed to produce elastic deformation, the bare wire end of the cable 15 is clamped by the top pressure plate 24 and the bottom pressure plate 22, the spring 25 is in a stretched state, and the slide 28 is located in the V-shaped groove a inside the guide groove 1 27.

[0049] At this time, the operator presses the slot plate 26 downward, so that the slot plate 26 further squeezes the top pressure plate 24 downward, causing the top pressure plate 24 to continue to deform downward, that is, at this time the slot plate 26 moves downward, and under the deflection provided by the torsion spring 212, the slide column 28 slides from the V-shaped groove a of the guide groove 1 27 into the inclined groove 1 b. At this time, under the action of multiple springs 25, the guide shaft 23 is pushed to slide upward on the bottom pressure plate 22, and at the same time, multiple guide shafts 23 drive the top pressure plate 24 to move upward synchronously. At this time, the top pressure plate 24 is no longer in contact with the bottom pressure plate 22, and no longer clamps the bare wire end of the cable 15. When the slide column 28 slides to the groove point d inside the guide groove 1 27, the top pressure plate 24 no longer moves upward, and the operator can remove the cable 15 from the bottom pressure plate 22 at this time, and the quick disconnection operation of the cable 15 is completed.

[0050] The second stage of use is to connect the cable 15 to the terminal 14. At this time, the state of the quick-release assembly is the same as the state of the first stage. Specifically, the multiple springs 25 do not produce elastic deformation, and the sliding column 28 is located at the groove point d in the guide groove 27.

[0051] At this time, the operator places the bare wire end of the cable 15 on the arch of the bottom pressure plate 22, and makes the bare wire end of the cable 15 fit the bottom pressure plate 22. After completion, the operator presses the slot plate 26 downward. Due to the height difference of the inclined slot 2 c of the guide slot 1 27, the slide column 28 can only move upward along the inclined slot 3 e in the guide slot 1 27. As the slot plate 26 moves downward, the slot plate 26 synchronously drives the top pressure plate 24 to move toward the bottom pressure plate 22. At the same time, multiple springs 25 are driven downward by multiple guide shafts 23 to stretch. When the slide column 28 slides to the guide slot When the bottom of the V-groove a 27 is reached, the top pressure plate 24 and the opposite surface of the bottom pressure plate 22 are in contact, and the operator no longer presses the groove plate 26. At this time, the top pressure plate 24 is limited by the sliding column 28 and the V-groove a and cannot move upward. Specifically, the quick-release and quick-install assembly runs to the initial state of the first use stage. At this time, the bare wire end of the cable 15 is clamped and limited by the top pressure plate 24 and the bottom pressure plate 22. At the same time, the bare wire end of the cable 15 is connected to the terminal 14 through the bottom pressure plate 22 and the terminal board 21 for electrical conduction. At this time, the quick wiring installation operation of the cable 15 is completed.

[0052] During the operation of the above quick-release and quick-install components:

[0053] The operator can quickly install and remove the cable 15 and the transformer 11 by simply pressing the slot plate 26. Compared with the traditional method of tightening and removing using tools, the time for connecting and disconnecting the cable 15 and the terminal 14 can be greatly reduced, shortening the time required for wiring installation. This can speed up the wiring progress of the entire power grid when a new transformer 11 is installed or the high-voltage power grid is expanded.

[0054] Example 2: During the connection between the cable 15 and the terminal 14, long-term operation of the transformer 11 or external vibration, thermal expansion and contraction, etc. may cause the connection between the terminal 14 and the cable 15 to become loose, resulting in poor contact or looseness.

[0055] like Figure 2 、 Figure 3 、 Figure 5 and Figures 7 to 10 As shown, in order to solve the above problem, a stable component is provided, which includes two bearing plates 32, and the two bearing plates 32 are symmetrically fixedly connected to the middle of the side of the support plate 31 away from the terminal 14. A guide groove 2 33 is provided on each of the two bearing plates 32, and a slider 34 is slidably connected inside each of the two guide grooves 2 33. The top of each of the two sliders 34 is fixedly connected to a connecting column 35, and the top of each of the two connecting columns 35 is fixedly connected to a rubber arc block 36. A three-section fixed connection is fixedly connected between the two connecting columns 35 on the side close to each other. The telescopic rod 37 includes two telescopic shafts and a fixed shaft. The two telescopic shafts are slidably connected to the fixed shaft, and the two telescopic shafts are respectively fixedly connected to the two connecting columns 35. The bottoms of the two supporting plates 32 are connected to a gear 38 that rotates together. The top pressure plate 24 is fixedly connected to the side close to the supporting plate 32 with an upper gear rod 39. The upper gear rod 39 extends downward away from the end of the top pressure plate 24. The support plate 31 is slidably connected to a lower gear rod 310. The end of the lower gear rod 310 close to the three-section telescopic rod 37 is fixedly connected to the fixed shaft of the three-section telescopic rod 37.

[0056] Among them: reference Figure 8 As shown, the second guide groove 33 is divided into a horizontal groove parallel to the bare wire end of the cable 15 and an inclined groove inclined toward the side away from the cable 15. Specifically, the horizontal groove is close to the support plate 31, and the inclined groove is away from the support plate 31.

[0057] Among them: reference Figure 8 As shown, the inner annular surface of the rubber arc block 36 is provided with anti-slip texture.

[0058] Among them: the upper gear rod 39 is engaged with the gear 38, and the upper gear rod 39 is engaged with the side of the gear 38 close to the support plate 31; the lower gear rod 310 is engaged with the gear 38, and the lower gear rod 310 is engaged with the top of the gear 38, and the lower gear rod 310 is staggered with the upper gear rod 39.

[0059] When the stabilizing assembly is in use, it is divided into two stages of use. The first stage of use is when the cable 15 is installed on the terminal 14, that is, when the top pressure plate 24 moves toward the bottom pressure plate 22. At this time, the initial state of the stabilizing assembly is: the two sliders 34 are located at the end of the second guide groove 33 on the same side away from the support plate 31, the two rubber arc blocks 36 do not interfere with the shell end of the cable 15, and the two telescopic axes of the three-section telescopic rod 37 extend from the fixed axis to both sides.

[0060] At this time, as the top pressure plate 24 moves downward, the top pressure plate 24 drives the upper gear rod 39 to move downward synchronously. In the process of the upper gear rod 39 moving downward, the upper gear rod 39 engages and drives the gear 38 to rotate. While the gear 38 rotates, it drives the lower gear rod 310 to move toward the support plate 31. While the lower gear rod 310 moves, it drives the fixed axis of the three-section telescopic rod 37 to move toward the support plate 31. Then, the three-section telescopic rod 37 drives the slider 34 and the rubber arc block 36 to move synchronously toward the support plate 31 through the connecting columns 35 at both ends. At this time, the two telescopic axes of the three-section telescopic rod 37 are When the slider 34 slides in the guide groove 2 33 to the end of the inclined groove close to the support plate 31, the two rubber arc blocks 36 contact and clamp the shell end of the cable 15. When the slider 34 slides in the guide groove 2 33 to the horizontal groove, the two rubber arc blocks 36 no longer squeeze the shell end of the cable 15. The top pressure plate 24 fits with the bottom pressure plate 22 and the quick disassembly assembly completes the installation of the cable 15. Then, the position of the upper gear rod 39 is fixed, that is, the state in which the two rubber arc blocks 36 clamp the cable 15 and apply pressure toward the terminal 14 is fixed.

[0061] The second stage of use is when the cable 15 needs to be removed from the terminal 14, that is, when the top pressure plate 24 moves away from the bottom pressure plate 22. At this time, the upper gear rod 39 drives the gear 38 to rotate in the opposite direction, and the gear 38 engages to drive the lower gear rod 310 to move in the direction away from the support plate 31, and then the slider 34 gradually slides inside the second guide groove 33 to the end of the inclined groove away from the support plate 31. In this process, when the slider 34 slides in the opposite direction in the horizontal groove of the second guide groove 33, the two rubber arc blocks 36 maintain clamping pressure on the cable 15 and pull the cable 15 a distance away from the terminal 14. When the slider 34 slides in the opposite direction in the inclined groove of the second guide groove 33, the two rubber arc blocks 36 move away from each other so that they no longer interfere with the cable 15.

[0062] During the operation of the above stable components:

[0063] By using two rubber arc blocks 36 to clamp the cable 15 and apply pressure toward the terminal 14 while the cable 15 is installed, the conductive contact between the cable 15 and the bottom pressure plate 22 can be made tighter, effectively preventing the connection from loosening due to factors such as vibration, thermal expansion and contraction, ensuring that the cable 15 and the terminal 14 always maintain a good electrical connection during the operation of the transformer 11, and reducing faults caused by poor contact.

[0064] At the same time, the cable 15 is clamped and limited by the two rubber arc blocks 36, so that the conductive contact between the cable 15 and the terminal 14 is closer. The close contact increases the contact area for current transmission, thereby reducing contact resistance, reducing energy loss during power transmission, improving power transmission efficiency, reducing heat generation at the connection part, and ensuring the stable operation of the high-voltage power grid system.

[0065] At the same time, during the process of removing the cable 15 from the terminal 14, the two rubber arc blocks 36 pull the cable 15 a distance away from the terminal 14. At the same time, the two rubber arc blocks 36 move away from each other until they do not interfere with the cable 15, so that the conductive contact between the cable 15 and the terminal 14 can be quickly separated. During the operation of the transformer 11, the connection between the bare wire end of the cable 15 and the bottom pressure plate 22 may be slightly adhered due to heat or other reasons. At this time, there is no need to manually pull the cable 15 out of the bottom pressure plate 22, which greatly saves disassembly time and improves the convenience of connecting and removing the wiring.
