Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and more specifically, to a transformer structure that is easy to assemble. Furthermore, it also relates to a transformer assembly including the aforementioned easy-to-assemble transformer structure. Background Technology
[0002] With the vigorous promotion of the national strategy for smart grids and energy transformation, the market demand for high-efficiency, energy-saving, and environmentally friendly transformer products is growing rapidly. New energy-grade first-efficiency laminated core transformers, with their high efficiency, low loss, and high reliability, have become the mainstream choice in the market.
[0003] In the prior art, a connection structure between the transformer body and the oil tank of a large-capacity transformer is disclosed. This structure uses angle steel, a fixing plate, and clamps to fix the transformer inside the oil tank, thereby improving the stability of the transformer within the oil tank. However, when using this device, firstly, the angle steel needs to be pre-welded to the inside of the oil tank, and the fixing plate needs to be connected to the clamps. Then, the transformer is hoisted into the oil tank. At this time, the transformer is prone to collision with the angle steel, causing damage.
[0004] In summary, how to solve the technical problem that existing transformers are easily damaged by bumps and knocks when being hoisted into the oil tank is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a transformer structure that is easy to assemble, which can solve the technical problem that existing transformers are easily damaged by bumps and knocks when being hoisted into the oil tank. Another purpose of this utility model is to provide a transformer assembly that includes the above-mentioned transformer structure that is easy to assemble.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A transformer structure that is easy to assemble includes:
[0008] Iron core lamination;
[0009] The clamping assembly includes upper and lower clamps that correspond one-to-one in the vertical direction to clamp and fix the iron core laminations. The upper and lower clamps are vertically connected by at least one first screw.
[0010] Multiple pull screws are vertically inserted between the two ends of the upper clamp and the two ends of the lower clamp, and the two ends of the pull screws are fastened to the upper clamp and the lower clamp respectively by a first nut;
[0011] An angle steel has through holes on its horizontal surface that are adapted to the pull rod, and bolt holes for connecting the oil tank are provided on its vertical surface.
[0012] The second nut is screwed onto the tie rod above the angle steel, and the second nut is used to cooperate with the first nut to clamp the angle steel.
[0013] In one embodiment, the upper clamp includes a high-pressure upper clamp and a low-pressure upper clamp that is horizontally aligned with the high-pressure upper clamp. The lower clamp includes a high-pressure lower clamp located below the high-pressure upper clamp and a low-pressure lower clamp that is horizontally aligned with the high-pressure lower clamp. The low-pressure lower clamp is located below the low-pressure upper clamp. Both ends of the high-pressure upper clamp and both ends of the low-pressure upper clamp are vertically connected by a second screw. Both ends of the high-pressure lower clamp and both ends of the low-pressure lower clamp are vertically connected by the second screw.
[0014] In one embodiment, the outer periphery of the pull screw, the first screw, and the second screw are all fitted with insulating sleeves.
[0015] In one embodiment, the middle portions of the high-pressure upper clamp and the low-pressure upper clamp are aligned with each other and provided with pull straps.
[0016] In one embodiment, the device further includes a pair of fastening plates disposed on the high-pressure upper clamp and the low-pressure upper clamp, wherein the pair of fastening plates are disposed in one-to-one correspondence with the pull strap, and the two ends of the pull strap are respectively disposed on the pair of fastening plates.
[0017] In one embodiment, the fastening plate includes a U-shaped structure, and the two ends of the fastening plate are respectively connected to the high-pressure upper clamp and the low-pressure upper clamp.
[0018] In one embodiment, the two ends of the fastening plate are welded to the corresponding upper clamp.
[0019] In one embodiment, the bottom of the lower clamp is provided with a pad, and a shock-absorbing pad is provided below the pad.
[0020] A transformer assembly comprising the easily assembled transformer structure and oil tank as described in any of the preceding claims.
[0021] In one embodiment, the inner side wall of the short side of the oil tank is provided with a lateral positioning member, the lateral positioning member is detachably connected to the vertical surface of the angle steel of the transformer structure that is easy to assemble, and the inner side wall of the long side of the oil tank is welded with an L-shaped support plate, the horizontal part of the L-shaped support plate is provided with a stud, and the stud is fixedly connected to the mounting hole at the horizontal end of the angle steel.
[0022] When using the easily assembled transformer structure provided by this utility model, firstly, a lower clamp is placed at the bottom of the core laminations, and an upper clamp is placed at the top of the core laminations. The middle parts of the upper and lower clamps are vertically connected by at least one first screw (for example, the first screw is tightened to the upper and lower clamps respectively by nuts). Then, a tie rod is vertically inserted between the two ends of the upper and lower clamps, and the operator rotates and tightens the first nut, thereby tightening the two ends of the tie rod to the upper and lower clamps respectively, completing the assembly of the transformer body. At this point, the transformer body can be hoisted into the oil tank using a hoisting device.
[0023] After the hoisting operation is completed, the angle steel is threaded through the through hole of the tie rod and the angle steel is effectively locked and fixed with the second nut to complete the installation of the angle steel. Then, the lateral positioning component set on the inner side wall of the short side of the oil tank is detachably connected to the vertical surface of the angle steel. For example, the lateral positioning component also has bolt holes. The bolt holes of the lateral positioning component are aligned with the bolt holes of the vertical surface of the angle steel, and then bolts are passed through and tightened to fix the lateral positioning component and the vertical surface of the angle steel, thereby restricting the displacement of the vessel body in the lateral (short side direction).
[0024] Next, the L-shaped support plates and angle steels symmetrically welded to the two inner walls of the long side of the tank are assembled and fixed. For example, each L-shaped support plate has a stud on its horizontal part, and the mounting holes at the horizontal end of the angle steel are simply for the studs of the L-shaped support plate to pass through the mounting holes, and then tightened with washers and nuts, etc., to fix the L-shaped support plate and angle steel vertically, thereby limiting the displacement of the tank body in the longitudinal (long side direction).
[0025] Furthermore, during installation, the transformer body is first hoisted into the oil tank, and then the angle steel is installed on the upper clamp, thus avoiding accidents caused by collisions and damage to the iron core laminations when they are hoisted into the oil tank. In summary, the easily assembled transformer structure provided by this utility model can solve the technical problem of existing transformers being easily damaged by collisions when hoisted into the oil tank.
[0026] In addition, this utility model also provides a transformer assembly including the above-mentioned easily assembled transformer structure. Attached Figure Description

Detailed Implementation
[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] The core of this invention is to provide a transformer structure that is easy to assemble, which solves the technical problem that existing transformers are easily damaged by bumps and knocks when being hoisted into the oil tank. Another core aspect of this invention is to provide a transformer assembly that includes the aforementioned easily assembled transformer structure.
[0038] Please refer to Figures 1 to 3 This specific embodiment provides a transformer structure that is easy to assemble, including:
[0039] Iron core lamination 1;
[0040] The clamping assembly includes an upper clamping member 2 and a lower clamping member 3 that are vertically aligned to clamp and fix the iron core lamination 1. The middle part of the upper clamping member 2 and the middle part of the lower clamping member 3 are vertically connected by at least one first screw 17.
[0041] Pull screw 4 is vertically inserted between the two ends of the upper clamp 2 and the two ends of the lower clamp 3. The two ends of pull screw 4 are fastened to the upper clamp 2 and the lower clamp 3 respectively by the first nut 5.
[0042] Angle steel 6 has a through hole 7 on its horizontal surface that is adapted to the tie rod 4, and a bolt hole 62 on its vertical surface for connecting the oil tank 9.
[0043] The second nut 8 is screwed onto the tie rod 4 above the angle steel 6. The second nut 8 is used to cooperate with the first nut 5 to clamp the angle steel 6.
[0044] It should be noted that by adopting a solution of "using fixed nuts instead of angle steel for fastening," the protruding angle steel was removed during the critical hoisting stage, reducing the width of the unit and increasing the gap between the unit and the inner wall of the oil tank 9. This completely avoids the risk of interference and collision during hoisting, making operation simpler and smoother, significantly improving assembly efficiency, and reducing the risk of product damage. Moreover, the unit structure with the angle steel temporarily removed is more compact, occupying less space when entering the drying chamber, which is conducive to hot air circulation and uniform heating, improving the drying effect and efficiency.
[0045] Furthermore, all improvements in this application are simple additions to the existing structure. The added fixing nuts (first nut 5 and second nut 8) and the lateral positioning parts 15 of the oil tank 9 are standard parts or simple machined parts, which add almost no extra cost, but bring about significant process improvements and quality enhancements, resulting in very significant economic benefits. In actual application, the shape, size, number, material, and specific location of the clamping assembly, the pull screw 4, the first nut 5, the second nut 8, and the angle steel 6 can be determined according to the actual situation and needs.
[0046] When using the easily assembled transformer structure provided by this utility model, firstly, a lower clamp 3 is placed at the bottom of the core lamination 1, and an upper clamp 2 is placed at the top of the core lamination 1. The middle of the upper clamp 2 and the middle of the lower clamp 3 are vertically connected by at least one first screw 17 (for example, the first screw 17 is fastened to the upper clamp 2 and the lower clamp 3 respectively by nuts). Then, a pull screw 4 is vertically inserted between the two ends of the upper clamp 2 and the two ends of the lower clamp 3, and the operator rotates and tightens the first nut 5, thereby fastening the two ends of the pull screw 4 to the upper clamp 2 and the lower clamp 3 respectively. At this time, the transformer body can be hoisted into the oil tank 9 using a hoisting device.
[0047] After the hoisting operation is completed, the through hole 7 of the angle steel 6 is passed through the tie rod 4, and the angle steel 6 is effectively locked and fixed by the second nut 8 to realize the installation operation of the angle steel 6. Then, the lateral positioning component 15 set on the inner side wall of the short side of the oil tank 9 is detachably connected to the vertical surface of the angle steel 6. For example, the lateral positioning component 15 also has bolt holes 62. The bolt holes 62 of the lateral positioning component 15 are aligned with the bolt holes 62 on the vertical surface of the angle steel 6, and then bolts are passed through and tightened to fix the lateral positioning component 15 and the vertical surface of the angle steel 6, thereby restricting the displacement of the body in the lateral (short side direction).
[0048] Next, the L-shaped support plates 16 and angle steel 6, which are symmetrically welded to the two inner sidewalls of the long side of the tank, are assembled and fixed. For example, each L-shaped support plate 16 has a stud 19 on its horizontal part, and the mounting hole 61 at the horizontal end of the angle steel 6 is such that the stud 19 of the L-shaped support plate 16 only needs to be passed through the mounting hole 61, and then tightened and fixed by components such as washers and nuts, so as to fix the L-shaped support plate 16 and angle steel 6 vertically, thereby limiting the displacement of the tank body in the longitudinal (long side direction).
[0049] Moreover, during installation, the iron core lamination 1 is first hoisted into the oil tank 9, and then the angle steel 6 is installed on the upper clamp 2, thereby avoiding the accident of the iron core lamination 1 being easily damaged by collision with the angle steel 6 when it is hoisted in.
[0050] In summary, the easily assembled transformer structure provided by this utility model can solve the technical problem that existing transformers are easily damaged by bumps when being hoisted into the oil tank 9.
[0051] In one embodiment, the upper clamp 2 includes a high-pressure upper clamp and a low-pressure upper clamp that is horizontally aligned with the high-pressure upper clamp. The lower clamp 3 includes a high-pressure lower clamp located below the high-pressure upper clamp and a low-pressure lower clamp that is horizontally aligned with the high-pressure lower clamp. The low-pressure lower clamp is located below the low-pressure upper clamp. Both ends of the high-pressure upper clamp and both ends of the low-pressure upper clamp are vertically connected by a second screw 18. Both ends of the high-pressure lower clamp and both ends of the low-pressure lower clamp are vertically connected by a second screw 18.
[0052] It should be noted that one side of the reactor body is the high-pressure side, and the other side is the low-pressure side. The high-pressure upper clamp, low-pressure upper clamp, high-pressure lower clamp, and low-pressure lower clamp can form a rectangular clamping frame to effectively clamp the core lamination 1. For example, in the axial direction of the core lamination 1, the high-pressure upper clamp, the high-pressure upper clamp, and the low-pressure lower clamp are clamped together by the second screw 18. In the longitudinal direction of the core lamination 1, the high-pressure upper clamp and the high-pressure lower clamp, the low-pressure upper clamp and the low-pressure lower clamp are clamped together by the first screw 17 and the pull screw 4.
[0053] In one embodiment, insulating sleeves 12 are fitted around the outer periphery of the pull screw 4, the first screw 17, and the second screw 18.
[0054] It should be noted that an insulating component is installed between the clamping assembly and the core lamination 1. Furthermore, insulating sleeves 12 can be fitted around the outer periphery of the tie rod 4, the first screw 17, and the second screw 18. This is because the screws and other components are metal and are very close to the ends of the windings and the clamping assembly. Under a high-voltage electric field, there is a high potential difference between the metal tie rod 4 and surrounding components (such as the windings, core, and clamps). After the insulating sleeves 12 are fitted, a robust, thick solid insulating barrier is established between the tie rod 4 and the surrounding high-voltage components. This effectively prevents surface discharge or air breakdown under high electric field conditions, ensuring the electrical safety of the transformer.
[0055] In one embodiment, a pull strap 13 is provided aligned with the middle of the high-voltage upper clamp and the middle of the low-voltage upper clamp. The pull strap 13 is used to fasten the two upper clamps 2 to further improve the stability of the core lamination 1. Of course, the pull strap 13 can also be omitted, in which case two upper clamps 2 arranged in the longitudinal direction can be provided between the two upper clamps 2 arranged in the transverse direction. Alternatively, the pull strap 13 can be a non-elastic rope structure, which has the effect of stable connection and preventing loosening.
[0056] In one embodiment, the device further includes a pair of fastening plates 14 arranged on the high-pressure upper clamp and the low-pressure upper clamp. The pair of fastening plates 14 are arranged in a one-to-one correspondence with the pull strap 13. The two ends of the pull strap 13 are respectively arranged on the pair of fastening plates 14. This arrangement ensures that the device structure is simple and also facilitates the installation of the pull strap 13.
[0057] In one embodiment, the fastening plate 14 includes a U-shaped structure, and the two ends of the fastening plate 14 are respectively connected to the high-pressure upper clamp and the low-pressure upper clamp, so as to simplify the structure of the device, facilitate installation, and improve the stability of the pull strap 13.
[0058] In one embodiment, the two ends of the fastening plate 14 are welded to the corresponding upper clamp 2 to ensure a stable connection between the fastening plate 14 and the upper clamp 2, which facilitates manufacturing and installation.
[0059] In one embodiment, the bottom of the lower clamp 3 is provided with a pad 10, and a shock-absorbing pad 11 is provided below the pad 10 to improve the safety of the iron core lamination 1 when it is placed, and to prevent the lower clamp 3, the pull screw 4 and the iron core lamination 1 from directly contacting the ground. The pad 10 and the shock-absorbing pad 11 help to ensure the safety and stability of the structure.
[0060] In addition to the transformer structure that is easy to assemble as described above, this utility model also provides a transformer assembly that includes the transformer structure that is easy to assemble as disclosed in the above embodiments. The transformer assembly also includes an oil tank 9, and the structure of the other parts of the transformer assembly can be found in the prior art, which will not be described in detail here.
[0061] In one embodiment, such as Figure 5 and Figure 6 As shown, the inner side wall of the short side of the oil tank 9 is provided with a lateral positioning component 15. The lateral positioning component 15 and the vertical surface of the angle steel 6 of the transformer structure that is easy to assemble are detachably connected. The inner side wall of the long side of the oil tank 9 is welded with an L-shaped support plate 16. The horizontal part of the L-shaped support plate 16 is provided with a stud 19. The stud 19 and the mounting hole 61 at the horizontal end of the angle steel 6 are fixedly connected.
[0062] It should be noted that the angle steel 6 is installed by passing through the through hole 7 through the tie rod 4 and effectively locking the angle steel 6 with the second nut 8. Then, the lateral positioning component 15, which is set on the inner side wall of the short side of the oil tank 9, is detachably connected to the vertical surface of the angle steel 6. For example, the lateral positioning component 15 is also provided with bolt holes 62. The bolt holes 62 of the lateral positioning component 15 are aligned with the bolt holes 62 on the vertical surface of the angle steel 6, and then bolts are passed through and tightened to fix the lateral positioning component 15 and the vertical surface of the angle steel 6, thereby restricting the displacement of the device body in the lateral (short side direction).
[0063] Next, the L-shaped support plates 16 and angle steel 6, which are symmetrically welded to the two inner sidewalls of the long side of the tank, are assembled and fixed. For example, each L-shaped support plate 16 has a stud 19 on its horizontal part, and the mounting hole 61 at the horizontal end of the angle steel 6 is such that the stud 19 of the L-shaped support plate 16 only needs to be passed through the mounting hole 61, and then tightened and fixed by components such as washers and nuts, so as to fix the L-shaped support plate 16 and angle steel 6 vertically, thereby limiting the displacement of the tank body in the longitudinal (long side direction).
[0064] Specifically, by assembling and fixing the lateral positioning component 15 welded to the short side of the oil tank 9 and the L-shaped support plate 16 welded to the long side of the oil tank 9 with the angle steel, the upper part of the reactor body is firmly connected to the oil tank 9, forming a strong axial constraint. This effectively prevents the reactor body from moving axially during operation and vibration, and limits the lateral displacement of the reactor body. Compared with traditional bottom positioning, this application can achieve comprehensive and stable "bottom-axial" positioning of the reactor body within the oil tank 9, greatly improving the mechanical stability and vibration resistance of the product.
[0065] To further illustrate the installation method of the transformer assembly provided by this utility model, the following example will be given.
[0066] 1. When assembling the vessel body, do not install the angle steel 6, and tighten the iron core laminations 1 by tightening the first nut 5;
[0067] 2. Place the secured device into a drying oven for drying.
[0068] 3. After drying, the device body is directly hoisted into the oil tank 9. Since there is no protruding angle steel 6, the hoisting is smooth and there is no risk of collision.
[0069] 4. After the core body is in place, install the angle steel 6, washers and second nuts 8 from the outside of the oil tank 9 in sequence to complete the final fixation of the iron core laminations 1.
[0070] 5. Fix the lateral positioning piece 15 on the inner side of the short side of the oil tank 9 to the vertical surface of the angle steel 6, and fix the stud 19 of the L-shaped support plate 16 to the mounting hole 61 at the end of the angle steel 6.
[0071] 6. Check whether the lateral positioning component 15 and the angle steel 6, and the L-shaped support plate 16 and the angle steel 6 are securely fastened. If necessary, make fine adjustments or tighten them to complete the assembly of the transformer components.
[0072] It should be noted that the first nut 5 and the second nut 8 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.
[0073] In addition, it should be noted that the orientation or positional relationship indicated by "vertical", "horizontal", etc. in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Similar or identical parts between embodiments can be referred to interchangeably.
