Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to an outdoor transformer with a lightning protection structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers can be classified according to their application as follows: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, angle transformers, high-current transformers, and excitation transformers.

[0003] Chinese Patent Publication No. CN 113363055 A discloses an outdoor rainproof and lightning-proof transformer. Through the installation of a baffle, the transformer body can directly dissipate heat through rainwater in rainy weather. Therefore, the baffle automatically seals the gaps between the heat sink fins, preventing rainwater mixed with dust and other impurities from falling onto the fins and causing poor heat dissipation. In sunny weather, as the water in the tank evaporates, the baffle automatically retracts and unfolds the heat sink fins, ensuring the heat sink fins effectively dissipate heat from the transformer body. The above-mentioned existing technical solution has the following shortcomings: the technical solution uses a rainproof pad to achieve the purpose of protecting the transformer from rain, but its coverage area for rainwater is limited during use, and the protection effect is low, leaving room for optimization.

[0004] Chinese Patent Publication No. CN 110491629 A discloses a rainproof transformer. This rainproof transformer uses a fixed base on the top of a support plate to fix a support column, which in turn fixes the rainproof top. The rainproof top effectively diverts rainwater, preventing it from accumulating on the top. A support rod on one side of the support plate supports a baffle to prevent rainwater from flowing into the heat dissipation holes and affecting the operation of the internal transformer, thus achieving rain protection. The existing technical solution has the following shortcomings: While the existing solution uses an externally added integral shell structure to achieve rain protection, resulting in a large rain-blocking area and good rain-blocking effect, the overall cost is high, it occupies a large area, and transportation is very inconvenient, leaving room for optimization. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor transformer with a lightning protection structure to solve the problem of limited rain protection effect for transformers mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an outdoor transformer with a lightning protection structure, comprising a column and a transformer body, wherein columns are fixed at the four corners of the top of the transformer body;

[0007] A top plate is fixed between the top ends of the columns, and a rainproof mechanism is provided on the outer side of the top plate. The rainproof mechanism includes a receiving groove, which is located inside the top plate. A second rotating shaft is rotatably connected inside the receiving groove, and a second gear is fixed to the outer side of the second rotating shaft. A servo motor is fixed to the bottom end of the top plate via a bracket, and the output shaft of the servo motor is connected to the second rotating shaft. First rotating shafts are rotatably connected to both sides inside the receiving groove, and first gears are fixed to the outer side of each first rotating shaft. The first gears mesh with the second gears. The bottom ends of the first rotating shafts extend to the outer side of the top plate and are rotatably connected to the top end of the columns. Pull ropes are wound around the outer side of each first rotating shaft. The bottom of the top plate... A shielding curtain is fixed at one end, and a positioning frame is fixed at the bottom end of the shielding curtain. A bottom curtain is fixed at the bottom end of the positioning frame, and iron plates are fixed at both ends of the inner side of the bottom curtain. A fixing seat is fixed at both ends of both sides of the transformer body, and an electromagnet is fixed at the top of each fixing seat. Two sets of extension blocks are fixed inside the positioning frame, and a guide block is fixed inside each extension block. The top of each guide block is connected to the bottom end of a pull rope. Guide rails are fixed on both sides of the transformer body, and guide grooves are provided inside each guide rail. Each guide groove is connected to a guide block. A pressure sensor is fixed at the bottom end of the guide groove. A rain sensor is fixed at the top end of the top plate, and a microcontroller is fixed at the bottom end of the top plate.

[0008] Preferably, the top of the interior of the blind curtain is uniformly fixed with positioning strips, and four sets of positioning strips are provided.

[0009] Preferably, ventilation openings are evenly arranged on both sides inside the curtain, and rain guards are fixed on the curtain on one side of the ventilation opening, and the cross-section of the rain guards is inclined.

[0010] Preferably, the width of the guide block matches the width of the guide groove, and both the guide block and the guide groove have convex cross-sections.

[0011] Preferably, the output terminals of the rain sensor and the pressure sensor are electrically connected to the input terminal of the microcontroller via wires, and the output terminal of the microcontroller is electrically connected to the output terminals of the electromagnet and the servo motor via wires respectively.

[0012] Preferably, a crossbar is fixed between the columns, and a guide seat is fixed on the outside of the crossbar, with a guide wheel rotatably connected inside the guide seat.

[0013] Preferably, the guide wheel has a groove inside, and the groove is connected to the pull rope.

[0014] Preferably, a lightning protection mechanism is provided at the top of the top plate, and the lightning protection mechanism includes a lightning protection network. The lightning protection network is fixed at the top of the top plate, and a lightning rod is fixed at the top of the lightning protection network. Grounding components are fixed on both sides of the lightning protection network, and four sets of insulating fixing blocks are fixed at the bottom of the lightning protection network, and the insulating fixing blocks are all connected to the top of the top plate.

[0015] Preferably, insulating support rods are fixed on both sides of the top of the lightning protection network, and insulating fixing sleeves are fixed on the top of the insulating support rods, and the insulating fixing sleeves are all sleeved on the outside of the lightning rod.

[0016] Preferably, the insulating support rod is connected to the lightning protection network by a second insulating bolt, and the insulating fixing sleeves are connected to each other by a first insulating bolt.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the outdoor transformer with lightning protection structure is equipped with a rainproof mechanism, which can expand the rainproof range and enhance the use effect while ensuring air circulation and heat dissipation. By being equipped with a lightning protection mechanism, it can achieve the purpose of limiting and protecting the lightning rod and reduce the impact of external weather on it.

[0018] A rainproof mechanism is installed on the outside of the transformer body. During operation, in rainy weather, the microcontroller controls the servo motor to start, which drives the second shaft and the second gear to rotate. This meshing action drives the first shaft, connected to the first gear, to rotate, thus releasing the pull ropes. The pull ropes on both sides move downwards, and their bottoms are fixed to the extension block and positioning frame. This allows the rainproof curtain to lower synchronously, achieving the purpose of protecting the transformer body from rain. Furthermore, the extension block creates a certain heat dissipation gap between the rainproof curtain and the transformer body. Combined with the rainproof eaves and vents, this allows for air circulation. The airflow is improved to prevent the curtain from sticking to the outside of the transformer body due to wind, thus affecting its heat dissipation. At the same time, during the synchronous downward movement of the guide block, it comes into contact with the pressure sensor and transmits the information to the microcontroller. This energizes the electromagnet, and during the descent of the curtain, the bottom curtain expands outward under the action of the inclined surface of the fixing seat. Under the action of magnetism, the bottom curtain is attracted and fixed to the outside of the fixing seat, so that the bottom curtain is in an inclined state, that is, the bottom is in a limited opening state that is not affected by rain and wind. This ensures airflow and heat dissipation, while expanding the rain-blocking range and enhancing practicality and flexibility.

[0019] A lightning protection mechanism is installed at the top of the top plate. During use, the lightning rod, lightning protection network and grounding components are installed to effectively improve the lightning protection effect of the transformer body. At the same time, the installation of insulating support rod, insulating fixing sleeve, first insulating bolt and second insulating bolt can achieve the purpose of reinforcing and limiting the lightning rod. That is, in windy weather, it can reduce the impact on the lightning rod and ensure the effectiveness of the lightning rod. Attached Figure Description

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.

[0031] Please see Figures 1-8 The present invention provides the following technical solution:

[0032] Example 1

[0033] To address the limited rain-blocking effect of existing technologies, the following solution is disclosed, specifically as follows: Figures 1-8As shown, the outdoor transformer with lightning protection structure provided in this application includes columns 5 and a transformer body 7. Columns 5 are fixed at the four corners of the top of the transformer body 7. A crossbar 11 is fixed between the columns 5, and a guide seat 12 is fixed to the outside of the crossbar 11. A guide wheel 13 is rotatably connected inside the guide seat 12. A wire groove is provided inside the guide wheel 13, and the wire groove is connected to a pull rope 210. A top plate 1 is fixed between the tops of the columns 5, and a rainproof mechanism 2 is provided on the outside of the top plate 1. The rainproof mechanism 2 includes a receiving groove 208, which is located inside the top plate 1. A second rotating shaft 214 is rotatably connected inside the receiving groove 208, and the second rotating shaft 214 is rotatably connected to the outside of the second rotating shaft 214. A second gear 213 is fixed to the side. A servo motor 212 is fixed to the bottom end of the top plate 1 via a bracket, and the output shaft of the servo motor 212 is connected to the second rotating shaft 214. First rotating shafts 209 are rotatably connected to both sides inside the receiving groove 208, and first gears 211 are fixed to the outer sides of each first rotating shaft 209. The first gears 211 mesh with the second gear 213. The bottom ends of the first rotating shafts 209 extend to the outer side of the top plate 1 and are rotatably connected to the top of the column 5. Pull ropes 210 are wound around the outer sides of each first rotating shaft 209. A blind curtain 201 is fixed to the bottom end of the top plate 1. Positioning strips 202 are evenly fixed to the top of the inside of the blind curtain 201, and the positioning strips 202 are provided with… Four sets of ventilation openings 215 are evenly arranged on both sides of the interior of the shielding curtain 201. A rain shield 203 is fixed to each shielding curtain 201 on one side of the ventilation opening 215. The cross-section of the rain shield 203 is inclined. A positioning frame 204 is fixed to the bottom of the shielding curtain 201. A bottom curtain 205 is fixed to the bottom of the positioning frame 204. Iron plates 216 are fixed to both ends of the inner side of the bottom curtain 205. Fixing seats 207 are fixed to both ends of both sides of the transformer body 7. Electromagnets 206 are fixed to the top of each fixing seat 207. Two sets of extension blocks 217 are fixed to the inner side of the positioning frame 204. Guide blocks 218 are fixed inside each extension block 217. The width of the guide block 218 is... The width of the groove 9 is matched. The cross-section of both the guide block 218 and the guide groove 9 is convex. The top of the guide block 218 is connected to the bottom of the pull rope 210. The two sides of the transformer body 7 are fixed with guide rails 6, and the guide rails 6 are all provided with guide grooves 9. The guide grooves 9 are all connected to the guide block 218. The bottom of the guide groove 9 is fixed with a pressure sensor 10. The top of the top plate 1 is fixed with a rain sensor 3. The output ends of the rain sensor 3 and the pressure sensor 10 are electrically connected to the input end of the microcontroller 8 through wires. The output end of the microcontroller 8 is electrically connected to the output ends of the electromagnet 206 and the servo motor 212 through wires respectively. The bottom of the top plate 1 is fixed with a microcontroller 8.

[0034] In this embodiment, during use, the microcontroller 8 controls the servo motor 212 to start on rainy days. This motor drives the second shaft 214 and the second gear 213 to rotate. In this meshing action, the first shaft 209, connected to the first gear 211, rotates, thus releasing the pull rope 210. This causes the pull ropes on both sides to move downwards, allowing the rain curtain 201 to be lowered simultaneously, achieving the purpose of protecting the transformer body 7 from rain. Furthermore, the extension block 217 creates a certain heat dissipation gap between the rain curtain 201 and the transformer body 7. Combined with the rain shield 203 and the vent 215, this allows for air circulation, thereby preventing rain damage caused by rain. The wind force causes it to adhere to the outside of the transformer body 7, affecting its heat dissipation. At the same time, during the synchronous downward movement of the guide block 218, it comes into contact with the pressure sensor 10 and transmits the information to the microcontroller 8, which energizes the electromagnet 206. During the descent of the curtain 201, the bottom curtain 205 expands outward under the action of the inclined surface of the fixing seat 207, and under the action of magnetism, the bottom curtain 205 is attracted and fixed to the outside of the fixing seat 207, so that the bottom curtain 205 is in an inclined state, that is, the bottom is in a limited opening state that is not affected by rain and wind, thereby ensuring air circulation and heat dissipation, while expanding the rain-blocking range and enhancing practicality and flexibility.

[0035] Example 2

[0036] This embodiment differs from Embodiment 1 in that by setting up the lightning protection mechanism 4, it can improve the lightning protection effect while simultaneously achieving the purpose of limiting and protecting the lightning protection components. Specifically, as shown below... Figure 1 and Figure 7 As shown, a lightning protection mechanism 4 is provided at the top of the top plate 1, and the lightning protection mechanism 4 includes a lightning protection net 401. The lightning protection net 401 is fixed to the top of the top plate 1. A lightning rod 403 is fixed at the top of the lightning protection net 401. Grounding components 408 are fixed on both sides of the lightning protection net 401. Four sets of insulating fixing blocks 407 are fixed at the bottom of the lightning protection net 401, and the insulating fixing blocks 407 are all connected to the top of the top plate 1. Insulating support rods 402 are fixed on both sides of the top of the lightning protection net 401, and insulating fixing sleeves 404 are fixed at the top of the insulating support rods 402.

The insulating support rods 402 are connected to the lightning protection net 401 by second insulating bolts 406. The insulating fixing sleeves 404 are connected to each other by first insulating bolts 405.

[0037] In this embodiment, by setting up a lightning rod 403, a lightning protection network 401, and a grounding component 408, the lightning protection effect of the transformer body 7 can be effectively improved. At the same time, by setting up an insulating support rod 402, an insulating fixing sleeve 404, a first insulating bolt 405, and a second insulating bolt 406, the lightning rod 403 can be reinforced and limited. That is, in windy weather, the impact on the lightning rod 403 can be reduced, ensuring the effectiveness of the lightning rod 403.
