Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a transformer potting and hoisting assembly and a transformer with the assembly. Background Art
[0002] Potting a transformer involves completely immersing the magnetic core and coils inside the transformer in asphalt or epoxy resin, forming a solid, impermeable protective layer. This effectively isolates the transformer from the effects of oxygen, moisture, and impurities in the environment, significantly improving its electrical performance.
[0003] The surface of the transformer after potting is relatively flat. For large transformers weighing several tons (refer to transformers with a capacity of 1600kVA), it is difficult to lift and move them. Utility Model Content
[0004] One of the purposes of the utility model is to solve the problem in the prior art that after potting, the surface of a large transformer is flat and difficult to lift and move.
[0005] A second object of the present utility model is to provide a transformer.
[0006] In order to achieve one of the above-mentioned purposes, the present invention adopts the following technical solution: a transformer potting and lifting assembly, comprising a vertical pole, a potting disk provided in the extension direction of the pole body of the vertical pole, the potting disk being larger than the vertical pole, the potting disk being a resistance structure extending around the vertical pole, the potting disk being provided with a through hole, the through hole penetrating the upper and lower end surfaces of the potting disk.
[0007] The head end of the vertical pole is connected to a tension head, the size of the tension head is larger than the vertical pole, and the tension head is a resistance structure extending around the vertical pole.
[0008] The above-mentioned transformer potting hoist assembly is used in transformer potting solutions. Therefore, when potting a transformer, the vertical rod is extended into the hollow area of the transformer body, exposing the tension head on the inner rod to the outside of the transformer body. The potting plate is then positioned within the hollow area of the transformer body. Epoxy resin is then potted into the transformer body. The flowing epoxy resin enters the hollow area of the transformer body and accumulates along the through-holes of the potting plate from the bottom of the transformer body until the entire hollow area of the transformer body is filled.
[0009] Finally, when the potting is completed and the epoxy resin forms a fixed layer, the vertical pole, potting disk and transformer body form a whole. At this time, the crane hook can be used to hook the tension head or the tension head can be tied with a rope to lift the vertical pole and then lift the transformer body.
[0010] The beneficial effects of the utility model are:
[0011] Before potting, a potting tray is placed into the hollow area of the transformer body using a vertical rod. During potting, the flowing epoxy resin is diverted through the through-holes of the potting tray. Once potting is complete and the epoxy resin forms a fixed layer, the vertical rod, potting tray, and transformer body form a single integrated structure. At this point, a tension head on the vertical rod head, exposed outside the transformer body, allows for lifting, lifting the vertical rod and transformer body together. This solves the existing problem of large transformers having a flat surface after potting, making it difficult to lift and move.
[0012] Furthermore, in an embodiment of the present invention, the vertical rod is a stainless steel screw rod, the potting plate is provided with a threaded hole, the through holes are distributed around the threaded hole, and the potting plate is threadedly connected to the vertical rod through the threaded hole.
[0013] Furthermore, in an embodiment of the present invention, the potting tray is a flat cylinder.
[0014] Furthermore, in an embodiment of the present invention, the vertical rod is arranged at the center of the potting tray.
[0015] Furthermore, in an embodiment of the present invention, the potting tray is made of epoxy resin, and there are three potting trays, which are spaced apart and arranged on the vertical pole.
[0016] Furthermore, in an embodiment of the present invention, the tension head is a flat cylinder, and the diameter of the tension head is smaller than the diameter of the potting disk.
[0017] In order to achieve the second of the above-mentioned purposes, the present invention adopts the following technical solution: a transformer, which has a transformer body and a transformer potting and lifting assembly as described in one of the above-mentioned invention purposes, the transformer body includes an annular magnetic core and a coil, and the coil is inserted into the annular magnetic core to form a turn-by-turn structure.
[0018] The vertical pole in the transformer potting and lifting assembly extends into the hollow area of the annular magnetic core, the tension head on the vertical pole is exposed outside the annular magnetic core, the potting disk is located in the hollow area of the annular magnetic core, and a gap is retained between the potting disk, the annular magnetic core and the coil.
[0019] Epoxy resin is potted between the coils, between the coils and the annular core, and between the potting disk, the annular core, and the coils, so that the pole, potting disk, annular core, and coils form a single unit. At this point, the pole head, exposed outside the transformer body, can be used to lift the pole and the transformer together, resolving the problem in existing technologies where large transformers, after potting, have a flat surface and are difficult to lift and move.
[0020] Furthermore, in an embodiment of the present invention, the transformer body also includes a support frame, which is arranged between the coil and the annular magnetic core, and the coil is embedded in the groove of the support frame to separate the coils from each other and the coil from the annular magnetic core.
[0021] Furthermore, in an embodiment of the present invention, the transformer body further includes a support base, the support base supports the annular magnetic core, and the support base separates the bottom portion of the annular magnetic core from the coil.
[0022] Furthermore, in an embodiment of the present invention, the transformer body further includes an isolation plate, and the isolation plate is installed on the top of the annular magnetic core so that the top of the annular magnetic core is separated from the coil.
[0023] Furthermore, in an embodiment of the present invention, the support seat and the isolation plate are both made of epoxy resin. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] It should be noted that the drawings in the specification are the contents of the specification. The structural shapes, connection relationships, coordination relationships, and positional relationships that can be obtained without any doubt in the drawings in the specification should be understood as the contents of the specification.
[0038] A transformer potting and lifting assembly, such as Figure 1 、 Figure 2 As shown, it includes a vertical pole 10, and a potting disk 11 is set in the extension direction of the rod body of the vertical pole 10. The potting disk 11 is larger than the vertical pole 10. The potting disk 11 is a resistance structure extending from the vertical pole 10 to the surrounding area. The potting disk 11 is provided with a through hole 12, and the through hole 12 passes through the upper and lower end surfaces of the potting disk 11.
[0039] The head end of the vertical pole 10 is connected to the tension head 13. The tension head 13 is larger than the vertical pole 10. The tension head 13 is a resistance structure extending from the vertical pole 10 to the surrounding area.
[0040] The above transformer potting hoisting components are used in the transformer potting treatment solution. Therefore, when the transformer needs to be potted, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the vertical rod 10 can be extended into the hollow area of the transformer body 20, so that the tension head 13 on the inner rod is exposed outside the transformer body 20, and the potting plate 11 is located in the hollow area of the transformer body 20. Epoxy resin is then potted into the transformer body 20. The flowing epoxy resin will enter the hollow area of the transformer body 20 and accumulate from the bottom of the transformer body 20 along the through-hole 12 of the potting plate 11 until the entire hollow area of the transformer body 20 is filled.
[0041] Finally, when potting is completed, as Figure 2 、 Figure 4 As shown, after the epoxy resin forms a fixed layer, the vertical pole 10, the potting plate 11 and the transformer body 20 form a whole. At this time, the tension head 13 can be hooked with a crane hook or tied with a pull rope to lift the vertical pole 10 and then lift the transformer body 20.
[0042] The advantage of the present invention lies in that, before potting, the potting tray 11 is placed into the hollow area of the transformer body 20 using the vertical pole 10. During potting, the flowing epoxy resin is avoided through the through holes 12 of the potting tray 11. After potting is completed and the epoxy resin forms a fixed layer, the vertical pole 10, potting tray 11 and transformer body 20 form a single integrated structure. At this point, the tension head 13 on the top of the vertical pole 10, which is exposed outside the transformer body 20, can be used to perform a lifting operation, thereby lifting the vertical pole 10 and transformer body 20 together. This solves the problem in the prior art that large transformers have a flat surface after potting, making it difficult to lift and move.
[0043] Specifically, if Figure 2 As shown, the vertical rod 10 is a stainless steel screw, the potting plate 11 is provided with a threaded hole, and the through holes 12 are distributed around the threaded hole. The potting plate 11 is threadedly connected to the vertical rod 10 through the threaded hole.
[0044] More specifically, if Figure 2 As shown, the potting tray 11 is a flat cylinder.
[0045] More specifically, if Figure 2 As shown, the vertical rod 10 is arranged at the center of the potting tray 11.
[0046] Specifically, if Figure 2 As shown, the potting disks 11 are made of epoxy resin, and there are three potting disks 11 , which are spaced apart and arranged on the vertical pole 10 .
[0047] More specifically, if Figure 2 As shown, the tension head 13 is a flat cylinder, and the diameter of the tension head 13 is smaller than the diameter of the potting disk 11 .
[0048] Example 2:
[0049] A transformer, such as Figures 1 to 3 As shown, the transformer has a transformer body 20 and the transformer potting and hoisting assembly in the above embodiment 1. The transformer body 20 includes a ring-shaped magnetic core 21 and a coil 22. The coil 22 is inserted into the ring-shaped magnetic core 21 to form a turn-by-turn structure.
[0050] The vertical pole 10 in the transformer potting and lifting assembly extends into the hollow area of the annular magnetic core 21, the tension head 13 on the vertical pole 10 is exposed outside the annular magnetic core 21, the potting disk 11 is located in the hollow area of the annular magnetic core 21, and a gap is retained between the potting disk 11 and the annular magnetic core 21 and the coil 22.
[0051] Epoxy resin is potted between coils 22, between coils 22 and toroidal core 21, and between potting disk 11, toroidal core 21, and coils 22, so that the vertical rod 10, potting disk 11, toroidal core 21, and coils 22 form a single unit. At this point, the tension head 13 on the top of the vertical rod 10, exposed outside the transformer body 20, can be used to lift the vertical rod 10 and the transformer body 20 together, solving the problem in the prior art of large transformers with flat surfaces after potting, making them difficult to lift and move.
[0052] Specifically, the transformer body 20 further includes a support frame 23 , which is disposed between the coil 22 and the annular core 21 . The coil 22 is embedded in a groove of the support frame 23 to separate the coils 22 from each other and from the annular core 21 .
[0053] Specifically, the transformer body 20 further includes a support base 30 , which supports the annular magnetic core 21 . The support base 30 separates the bottom portion of the annular magnetic core 21 from the coil 22 .
[0054] More specifically, the transformer body 20 further includes an isolation plate 40 . The isolation plate 40 is installed on the top of the annular core 21 , so that the top of the annular core 21 is separated from the coil 22 .
[0055] More specifically, the support base 30 and the isolation plate 40 are both made of epoxy resin.
[0056] Although the above describes the illustrative specific embodiments of the present invention so that technicians in this technical field can understand the present invention, the present invention is not limited to the scope of the specific embodiments. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present invention defined and determined by the attached claims, all utility model creations using the concept of the present invention are protected.
