Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a compact transformer based on a smart grid. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Existing compact transformers have poor buffering capacity, which cannot prevent damage when the equipment is hit, and poor heat dissipation capacity, which cannot send cold air from the outside into the equipment for cooling. In the invention patent with publication number CN114709043A, a compact transformer including an outer casing is disclosed, which achieves the purpose of improving buffering capacity, preventing damage when the equipment is hit, and improving heat dissipation capacity, which can send cold air from the outside into the equipment for cooling.

[0003] Although this device has the advantages mentioned above, it still has the following drawbacks in practical use: 1) The device uses a highly complex structure, such as an elastic arc plate for protection, which results in high actual manufacturing and replacement costs, making the equipment difficult to produce and costly to use. 2) The device uses the deformation of the elastic arc plate for buffering, which makes it easy for foreign objects to get stuck and affect the actual use effect. In addition, there are protective gaps between the elastic arc plates, resulting in poor actual protection effect.

[0004] Therefore, it is necessary to address the problems that still exist in the existing devices. Summary of the Invention

It solves the problems of high production difficulty and high operating costs in compact transformers, where the external elastic arc plate deformation is used to achieve a buffering effect.

[0010] Preferably, a discharge unit is provided on the outside of the conduit. The discharge unit includes a discharge port, which is located at the bottom inside the solid box and is in a through state. A filter barrel is fixedly connected inside the discharge port, and a support column is provided on the outside of the filter barrel. One end of the support column is fixedly connected to the bottom of the outer surface of the solid box.

[0011] Preferably, a rotating ring is rotatably connected inside the feed inlet, and a retaining ring is rotatably connected to the outer surface of the rotating ring.

[0014] Beneficial effects This invention provides a compact transformer based on a smart grid. Compared with existing technologies, it has the following advantages: (1) By setting up a protective mechanism, the bolts are connected to the two outer screw holes and the slide groove, so that the shell can be fixed outside the slide frame and the slide frame can be slidably installed outside the fixed frame. The shell can be slid by the slide frame, which can buffer the impact from the outside. At the same time, the shell is integrally formed and completely covers one side of the outside of the fixed box, which reduces the manufacturing difficulty and cost, increases the protection range, avoids the problem of protection leakage area, and avoids the problem of being stuck by foreign objects by the overall sliding, thus avoiding the problem of affecting the protection effect.

[0015] (2) By setting up a dehumidification component, the air drawn in through the air hole, solid groove and rubber tube can be blown into the solid box through the sliding hole to dissipate heat on the transformer body. At the same time, the cone can increase the air flow pressure, so that the air pushes the sliding plate from the sliding hole into the solid box and causes the shielding sliding sleeve to unfold. This can increase the adsorption range and allow air to flow into the solid box through the gap of the sliding sleeve. At the same time, the sliding plate slides back into the sliding hole to compress the sliding sleeve, so that the water vapor adsorbed by the sliding sleeve condenses and is discharged through the guide tube, thereby avoiding the problem of external water vapor damaging the transformer body.

[0016] (3) By setting up a discharge unit, the air after heat exchange and the condensate guided by the flow are discharged to the outside of the solid frame through the material port. Through contact with the rotary blade, the rotary blade can rotate around the rotating ring and drive the abutment to rotate. The abutment moves the spring plate to deform, so that the solid column transmits the vibration to the filter barrel. This can prevent external dust and impurities from adhering to the outside of the filter barrel and affecting the air flow and heat dissipation effect inside the solid box.

[0017] (4) By setting up a buffer component, when an external object hits the casing, the casing pushes the slide frame to slide along the fixed frame. At the same time, the slide frame pushes the slide rod to slide along through the action of the screw sleeve and the fixed plate, so that the slider follows the slide. The movement of the slider compresses the output end of the spring rod through the action of the rotating frame, thereby buffering the external impact force through the elastic force of the spring rod. This can not only prevent the fixed box from being hit and affecting the use of the transformer body, but also reduce the damage to the casing through buffering, thereby extending the service life of the casing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6 This invention provides a technical solution: a compact transformer based on a smart grid. The system includes a transformer body 1, with an external protective mechanism. This mechanism includes a fixed housing 2, which is fitted over the transformer body 1. The fixed housing 2 has a through-hole 3, allowing outside air to flow into it for heat dissipation from the transformer body 1. Condensation from the top of the sliding hole 3 is channeled through a funnel (not shown in the diagram). A fixed frame 5 is fixedly connected to the outer surface of the fixed housing 2, providing support, guiding movement, and sealing. The interior of the fixed frame 5 is connected to the interior of the sliding hole 3. A sliding frame 6 with a perforated outer surface is slidably connected to the outer surface of the fixed frame 5. The perforated design of the sliding frame 6 reduces its own weight, thereby reducing contact wear with the fixed frame 5. A skin 8 is provided on the outer surface of the sliding frame 6. The skin 8 is made of a material with high hardness, pressure resistance, wear resistance, and corrosion resistance. It can be integrally formed by stamping, thereby reducing production difficulty and usage costs. The body of the skin 8 has through-holes 9, which act as filter holes, facilitating air flow and filtering external impurities. A fixed groove 10 is fixedly connected to the perforated part of the sliding frame 6. The solid groove 10 serves to connect and guide the flow. Its interior is connected to the interior of the air hole 9. One side of the solid groove 10 has an inner chamfer 11, which is flush with the interior of the lowest air hole 9. This flushness prevents external liquid water from contacting the interior of the solid groove 10, thus avoiding bacterial growth and corrosion of the outer casing 8. A solid pipe 12 runs through the interior of the solid groove 10, serving the same function. The outer surface of the solid pipe 12 is fixedly connected to the body of the sliding frame 6, and one end of the solid pipe 12 is connected to a rubber tube 1. 3. The rubber tube 13 is made of rubber material. One end of the rubber tube 13 is flattened and can be seen to open under air pressure, so that outside air can flow into the solid box 2 to dissipate heat from the transformer body 1. After the air flows, the flattened end of the rubber tube 13 can close, which can avoid the problem of reverse air flow. The solid frame 5 has a through groove 14, which is connected to one end of the rubber tube 13. When the casing 8 is fixed to the solid frame 5, outside air can be blown into the solid box 2 through the through groove 14. One end of the rubber tube 13 is connected to the inside of the sliding frame 6 through the through groove 14.

[0022] The outer surfaces of the casing 8, the sliding frame 6, and the fixed frame 5 are provided with screw holes 15. Bolts 16 are threaded into the screw holes 15. The bolts 16 can be threaded into the three screw holes 15 to complete the fixed installation of the casing 8, the sliding frame 6, and the fixed frame 5. The outer surface of the fixed frame 5 is provided with a sliding groove 17. The inner width of the sliding groove 17 is adapted to the outer diameter of one end of the bolt 16, which can guide and limit the movement of the casing 8 and the sliding frame 6. The inside of the sliding groove 17 is connected to the inside of the inner screw hole 15. The sliding groove 17 and the screw hole 15 are located on the outer side of the fixed frame 5 so that the casing 8 can be covered when sliding, thereby preventing impurities from entering the inside of the sliding groove 17. One end of the bolt 16 is slidably connected to the inside of the sliding groove 17.

[0023] The interior of the sliding hole 3 is equipped with a dehumidification component 4, which includes a fixed ring 41. The fixed ring 41 serves as a fixed support, and its outer surface is fixedly connected to the interior of the sliding hole 3. A sliding sleeve 42 is fixedly connected to the outer surface of the fixed ring 41. The sliding sleeve 42 is made of woven fiber with good adsorption properties and is folded inside the sliding hole 3. A sponge pad can be placed inside the sliding sleeve 42 to further enhance the adsorption effect of water vapor. A sliding plate 43 is fixedly connected to the outer surface of the sliding sleeve 42. The sliding plate 43 serves as a seal, sliding guide, and dehydration device. The outer surface of the sliding plate 43 is slidably connected to both the sliding hole 3 and the interior of the fixed box 2.

[0024] The sliding hole 3 is internally connected to a conduit 44, which guides the condensate to the outside of the solid box 2 in an orderly manner, thus preventing the condensate from damaging the transformer body 1. One end of the conduit 44 is fixedly connected to the solid box 2 and extends into the solid box 2. A cone shroud 46 is fixedly connected to the outer surface of the solid ring 41. The cone shroud 46 guides and pressurizes the flowing air and also guides the condensate. The sliding sleeve 42 is slidably fitted on the outside of the cone shroud 46. A pin 47 is slidably connected to the solid ring 41. The pin 47 guides and limits the movement of the slide plate 43. The outer surface of the pin 47 is slidably connected to the solid frame 5, the sliding hole 3, and the inside of the solid box 2. One end of the pin 47 is fixedly connected to the outer surface of the slide plate 43. As a preferred embodiment, a compression spring is fitted on the outside of the pin 47. The two ends of the compression spring are fixedly connected to the outer surface of the pin 47 and the outer surface of the solid ring 41, respectively. The spring force allows the slide plate 43 to slide and reset.

[0025] The outside of the conduit 44 is provided with a discharge unit 45, which includes a discharge port 451. The discharge port 451 is located at the bottom inside the solid box 2 and is in a through state. It can facilitate the discharge of air and condensate, and prevent external impurities from entering the solid box 2. It can also achieve natural heat dissipation when stationary. A filter barrel 452 is fixedly connected inside the discharge port 451. The filter holes of the filter barrel 452 can facilitate air flow and prevent external impurities from entering the solid box 2 and causing damage to the transformer body 1. A support column 453 is provided outside the filter barrel 452. The support column 453 serves to elevate the filter barrel 452, which can facilitate the discharge of air and condensate and prevent the filter barrel 452 from bearing the weight. One end of the support column 453 is fixedly connected to the bottom of the outer surface of the solid box 2.

[0026] The feed inlet 451 is internally connected to a rotating ring 454, which serves to connect, fix, and guide movement. The outer surface of the rotating ring 454 is embedded with a rotating retaining ring 455, which serves to connect, support, and limit movement. The outer surface of the retaining ring 455 is fixedly connected to the inside of the feed inlet 451. The inner ring of the rotating ring 454 is fixedly connected to a swirl vane 456, which rotates by contacting condensate and flowing air. The filter barrel 452 is internally fixedly connected to a fixed column 457, which serves to fix and support. The outer surface of the fixed column 457 is fixedly connected to a spring plate 458, which is made of a material with high hardness, good toughness, pressure resistance, wear resistance, corrosion resistance, and fatigue resistance. It generates vibration through its own deformation. The outer surface of the swirl vane 456 is fixedly connected to a stop post 459, which is made of a material with high hardness, pressure resistance, wear resistance, and corrosion resistance. The outer surface of the stop post 459 abuts against the outer surface of the spring plate 458.

[0027] A buffer assembly 7 is provided on the outside of the sliding frame 6. The buffer assembly 7 includes a sliding rod 71, which serves as a sliding guide and connection. The outer surface of the sliding rod 71 is slidably connected to the inside of the fixed frame 5. One end of the sliding rod 71 is slidably connected to the body of the fixed box 2 and extends into the inside of the fixed box 2. A slider 72 is fixedly connected to one end of the sliding rod 71. The slider 72 serves as a connection and support. A spring rod 73 is provided on the outside of the slider 72. The spring rod 73 is made of fatigue-resistant material and can buffer and dampen the impact force of external impact through elasticity. Both ends of the spring rod 73 are rotatably connected to a rotating frame 74, which serves as a connection and support. The outer surface of one rotating frame 74 is fixedly connected to the outer surface of the slider 72, and the outer surface of the other rotating frame 74 is fixedly connected to a bracket 75, which serves as a fixed support. The outer surface of the bracket 75 is fixedly connected to the inside of the fixed box 2 and the outer surface of the transformer body 1.

[0028] The other end of the slide rod 71 is threadedly connected to a threaded sleeve 76. The threaded sleeve 76 is threadedly connected to the end of the slide rod 71, which facilitates quick assembly and disassembly. A fixed plate 77 is rotatably connected through the outer surface of the threaded sleeve 76. The fixed plate 77 serves as a fixed support and is provided with an axial limiting measure (not shown in the figure) for its connection with the threaded sleeve 76. As a preferred method, one end of the pin 47 can be fixedly connected to the fixed plate 77 or threadedly connected through the threaded sleeve 76. The outer surface of the fixed plate 77 is fixedly connected to the interior of the slide frame 6 and abuts against the outer surface of the fixed frame 5.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: First, the transformer body 1 is fixedly installed on the bracket 75 inside the fixed box 2 using the mounting fastener. Then, the sliding frame 6 is slidably fitted onto the fixed frame 5 on the outside and top of the fixed box 2. Next, the casing 8 is slidably fitted onto the outside of the sliding frame 6. Then, the screw holes 15 of the casing 8, the sliding frame 6, and the fixed frame 5 are aligned inside and outside. Then, the bolts 16 are inserted into the three screw holes 15 to complete the fixed installation of the sliding frame 6 and the casing 8. Next, the fixed box 2 is installed on the work position using the support column 453. Then, the bolts 16 are screwed outward so that one end of the bolt 16 is smoothly inside the sliding groove 17. When an external object impacts the transformer body 1 at its working position, the casing 8 contacts it through a large contact area. The impact force then pushes the sliding frame 6 along the fixed frame 5 towards the fixed box 2. During this process, one end of the bolt 16 slides synchronously inside the sliding groove 17, guiding and limiting the movement of the casing 8. Simultaneously, through the action of the fixed plate 77 and the screw sleeve 76, the sliding rod 71 drives the slider 72 to slide. The movement of the slider 72 compresses the output end of the spring rod 73 through the action of the rotating frame 74. The elastic force of the spring rod 73 buffers the impact force. Simultaneously, the movement of the casing 8 compresses the air between the fixed frame 5 and the sliding frame 6 into the interior of the fixed box 2 through the sliding hole 3. The transformer body 1 is cooled by airflow. When the sliding frame 6 drives the casing 8 to reset, the external air pressure is greater than the internal air pressure of the fixed frame 5. The outside air is blown into the rubber tube 13 through the air hole 9, the fixed groove 10, and the fixed tube 12. The air pressure then opens the flat end of the rubber tube 13, allowing air to enter the interior of the sliding frame 6 and the fixed frame 5. After the air pressure is balanced, one end of the rubber tube 13 is reshaped and becomes a flat closed state. This prevents air leakage when the casing 8 compresses air into the solid box 2. When the sliding frame 6 and the casing 8 are completely fixed to the fixed frame 5, one end of the rubber tube 13 blows air directly into the interior of the fixed frame 5 through the connecting groove 14, and then blows it into the interior of the solid box 2 through the sliding hole 3. When air flows into the sliding hole 3, it is further pressurized by the solid ring 41 and the cone cover 46 and blows directly into the sliding sleeve 42 and the sliding plate 43, causing the sliding plate 43 to slide into the solid box 2. The spring is compressed by the pin 47, or the pin 47 is fixed to the solid plate 77 and slides synchronously with the sliding frame 6 to push the sliding plate 43 into the solid box 2. When the sliding plate 43 is pushed, the folded sliding sleeve 42 unfolds, thereby adsorbing the water vapor mixed in the air through contact with the air. The dry air is blown into the solid box 2 through the fiber gaps of the sliding sleeve 42 and dissipates heat to the transformer body 1 through the flow. When the sliding plate 43 returns to its original position and slides into the sliding hole 3, it compresses the sliding sleeve 42, causing the adsorbed water vapor to become condensate. The condensate is discharged through the cone cover 46 and the conduit 44. Condensate is discharged to the outside of the solid box 2 through the feed port 451 and the filter holes of the filter barrel 452 via the guide and flowing air. The two, through contact with the rotary vane 456, drive the rotary vane 456 and the rotating ring 454 to rotate around the retaining ring 455. At the same time, the rotary vane 456 drives the abutment column 459 to rotate synchronously. The rotation of the abutment column 459 abuts against the spring plate 458, causing the spring plate 458 to deform and generate vibration. The solid column 457 then transmits the vibration to the filter barrel 452. The vibration of the filter barrel 452 causes the impurities attached to the surface to fall off, thereby avoiding the impurities from covering and affecting the smoothness of the filter holes. The flow of air and condensate can also wash away the impurities.
