Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer with a lead-out device. Background Art

[0002] In modern power systems, the transformer body is a key device for power transmission and distribution. With the help of the principle of electromagnetic induction, it can efficiently realize the conversion of voltage and current levels between multiple coils, thereby achieving stable transmission of electric energy. The transformer body is widely distributed in various power links and is a core component to ensure stable and reliable power supply.

[0003] A utility model patent with announcement number CN219591216U proposes a transformer with a lead-out device. In the patent, a rainproof top plate is located above the transformer. During maintenance work, the maintenance personnel have limited operating space due to the obstruction of the rainproof top plate. If the operating space is to be increased, the rainproof top plate needs to be disassembled first, which takes a lot of time and affects the maintenance efficiency.

[0004] Electric poles are prone to tilt due to factors such as geological conditions and external forces. Once the electric poles are tilted, when installing the transformer, the contact surface between the clamp and the pole becomes smaller, which will cause the clamping force on the pole to decrease, resulting in poor stability and the risk of shaking during the operation of the transformer.

[0005] At the same time, the installation crossarm of the transformer is fixed in length, and the clamp is installed on the end of the crossarm by bolts. When encountering poles with different spacings during installation, it is inconvenient to quickly adjust the position of the clamp on the crossarm, resulting in low installation efficiency of the transformer.

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 and Fig.13As shown, a transformer with a lead-out device described in the present invention includes a cross arm 1, a transformer body 2 installed on the cross arm 1, a first adjustment structure 3 installed on the cross arm 1, a second adjustment structure 4 installed on the first adjustment structure 3, an inspection structure 5 installed on the transformer body 2, a fixing structure 7 provided on the inspection structure 5, a rainproof top plate 9 installed on the inspection structure 5, and a lead-out structure 6 installed on the rainproof top plate 9; the lead-out structure 6 includes a conductive sleeve 601 installed on the rainproof top plate 9 and a limiting terminal 602 installed in the conductive sleeve 601, a positioning rod 603 is installed on the limiting terminal 602, and a conductive The conductive plug rod 604 is provided with a lightning rod 605, and the conductive sleeve 601 is provided with a grounding wire 606; the maintenance structure 5 comprises a mounting frame 501 installed on the transformer body 2 and four rotating rods 502 installed on the mounting frame 501, the rainproof top plate 9 is fixedly connected to the four rotating rods 502, wherein a fixed shaft 503 is fixedly connected between two of the rotating rods 502, the fixed shaft 503 is rotatably connected to the mounting frame 501, a gear 504 is installed on the fixed shaft 503, a hydraulic rod 507 is installed on the mounting frame 501, the telescopic end of the hydraulic rod 507 is fixedly connected to a connecting rod 506, and a rack 505 is fixedly connected to the connecting rod 506.

[0041] Specifically, Figure 6 , Figure 7 and Fig.12As shown, the fixed structure 7 includes four fixed rods 701 slidably connected to the mounting frame 501 and a connecting block 702 fixedly connected to the bottom of the fixed rod 701, the four fixed rods 701 are respectively engaged with the four rotating rods 502, the connecting block 702 is rotatably connected with a driving shaft 703, four driving blocks 704 are slidably connected in the mounting frame 501, a sliding rod 706 is fixedly connected between every two driving blocks 704, a driving groove 705 is provided on the driving block 704, the driving shaft 703 and the driving groove 705 are rollingly matched, a fixed plate 708 is fixedly connected between two sliding rods 706, one of the sliding rods 706 is fixedly connected with a push rod 707, and the push rod 707 pushes against the connecting rod 506 A second spring 710 is fixedly connected between the fixing rod 701 and the mounting frame 501, and a guide rod 709 is fixedly connected inside the mounting frame 501. The fixing rod 701 is slidably connected to the guide rod 709. When lightning strikes, the lightning is attracted by the lightning rod 605, and the lightning is conducted along the conductive plug rod 604 and the conductive bushing 601 to the grounding wire 606, and finally the lightning is safely led into the ground through the grounding wire 606. The lead-out rotating rod 502 is made of insulating material, which can effectively prevent lightning from being conducted to the transformer body 2, providing reliable lightning protection for the transformer body 2, reducing the risk of damage to the transformer body 2 caused by lightning strikes, and ensuring the stable operation of the power system. When it is necessary to overhaul the bushing and other components above the transformer body 2, The hydraulic rod 507 can be started. When the telescopic end of the hydraulic rod 507 is extended, it drives the connecting rod 506 to move upward. The movement of the connecting rod 506 makes the resisting rod 707 no longer subject to the resisting force. At this time, the fixed rod 701 slides under the action of the second spring 710. When the fixed rod 701 slides, it slides with the guide rod 709. The setting of the guide rod 709 makes the sliding of the fixed rod 701 more stable and smooth. The fixed rod 701 drives the connecting block 702 to move. The movement of the connecting block 702 drives the driving shaft 703 to roll in the driving groove 705, so that the driving block 704 drives the sliding rod 706 to move upward. The sliding rod 706 on one side drives the sliding rod 706 on the other side to move upward synchronously through the fixing plate 708. At the same time, the fixed rod 701 is no longer engaged with the rotating rod 502. The rack 505 is meshed with the gear 504. At this time, the hydraulic rod 507 continues to extend, driving the rack 505 to move upward. The rack 505 drives the gear 504 and the fixed shaft 503 to rotate, so that the fixed shaft 503 drives the rainproof top plate 9 to rotate. After rotating ninety degrees, the rainproof top plate 9 no longer blocks the casing and other components, providing an open operating space for repairing the casing and other components, improving the repair efficiency and reducing the repair time. When the repair is completed, the hydraulic rod 507 is fully retracted to make the four rotating rods 502 remain in a vertical state with the mounting frame 501. At this time, the connecting rod 506 at the telescopic end of the hydraulic rod 507 is allowed to resist the push rod 707 and move downward. The push rod 707 cooperates with the drive block 704 and other components to re-engage the fixed rod 701 with the rotating rod 502.The fixing of the rotating rod 502 is completed. The rotating rod 502 is fixed by the fixing rod 701 to prevent the vibration during the operation of the transformer body 2 from causing the meshing part of the gear 504 to wear more severely, causing the rainproof top plate 9 to loosen and affect its protective performance. The four rotating rods 502 are fixed by the fixing rod 701, which effectively disperses the impact of vibration, avoids the wear of the gear 504, and ensures that the rainproof top plate 9 always remains stable.

[0042] Specifically, Figure 1 , Figure 2 , Fig.10 , Fig.11 , Fig.13 and Fig.14As shown, the first adjustment structure 3 includes four adjustment rods 301 slidably connected to the cross arm 1 and an anti-dropping block 302 fixedly connected to the adjustment rod 301, the anti-dropping block 302 is slidably connected to the cross arm 1, two mounting plates 303 are slidably connected to the cross arm 1, two limit blocks 304 are fixedly connected to the mounting plate 303, a plurality of limit grooves 305 are provided on the adjustment rod 301, the four limit blocks 304 are respectively engaged with the limit grooves 305 on the four adjustment rods 301, a pressing shaft 307 is rotatably connected to the mounting plate 303, a threaded sleeve 308 is fixedly connected to the pressing shaft 307, two threaded columns 309 are fixedly connected to the cross arm 1, and a scale bar 310 is provided on the adjustment rod 301. A first spring 306 is fixedly connected between the mounting plate 303 and the cross arm 1, and the second adjustment structure 4 includes an adjustment shaft 401 rotatably connected to the adjustment rod 301 and an adjustment block 402 fixedly connected to each of the two adjustment shafts 401, a mounting block 403 is installed on the adjustment block 402, and a clamp is installed on the mounting block 403, wherein two of the adjustment shafts 401 are fixedly connected with a worm gear 404, wherein two of the adjustment rods 301 are rotatably connected with a worm 405, and the worm gear 404 is meshed with the worm 405, wherein two of the adjustment shafts 401 are provided with a fixing groove 407, wherein two of the adjustment rods 301 are slidably connected with a fixing block 406, and the two fixing blocks 406 are respectively connected to the two adjustment shafts The fixing groove 407 on 401 is engaged, and the fixing block 406 is threadedly connected with a first screw rod 408, and the first screw rod 408 is rotatably connected to the adjusting rod 301. When the transformer body 2 needs to be installed, the cross arm 1 is first placed between the two poles, and then the pressing shaft 307 is pressed downward, and the pressing shaft 307 moves downward to drive the mounting plate 303 to slide. The sliding of the mounting plate 303 causes the first spring 306 to contract, and at the same time, the mounting plate 303 drives the limiting block 304 to no longer engage with the limiting groove 305. When the pressing shaft 307 moves downward to a certain position, the pressing shaft 307 is driven to rotate with the help of the threaded sleeve 308, so that the threaded sleeve 308 and the threaded column 309 are threadedly matched. At this time, the mounting plate 303 will not be in the first spring 306. When the adjusting rod 301 slides, the anti-dropping block 302 is driven to slide. The anti-dropping block 302 can prevent the adjusting rod 301 from slipping off the cross arm 1, thereby avoiding the dangerous situation of accidental falling during installation or use. During the sliding process, the length of the adjusting rod 301 sliding out of the cross arm 1 can be flexibly controlled according to the actual distance between the two poles. At the same time, by observing the scale bar 310 on the adjusting rod 301, the sliding distance of the adjusting rods 301 on both sides is kept consistent, thereby ensuring the accuracy and balance of the installation. When the adjustment is completed, it is only necessary to make the threaded sleeve 308 no longer threadably cooperate with the threaded column 309, and the mounting plate 303 will be reset under the elastic force of the first spring 306.The limit block 304 is re-engaged with the limit groove 305 to complete the adjustment of the adjustment rod 301. By sliding the adjustment rod 301 and the cross arm 1, it is not only convenient to flexibly adjust the position of the clamp according to the different spacings between the poles to adapt to poles with various spacings, thereby improving the versatility of installation, but also during transportation, the adjustment rod 301 can be retracted into the cross arm 1, reducing the occupied space and facilitating transportation and storage. When the adjustment is completed, the transformer body 2 is installed on the cross arm 1, and then the transformer body 2 and the cross arm 1 are lifted together by the lifting equipment. After lifting to the specified position, carefully observe whether the pole is tilted. If the pole is tilted, the inner six sleeves can be inserted into the hexagonal block on the worm 405, and then the worm 405 can be rotated. When the worm 405 rotates, the worm wheel 404 is driven to rotate, and the rotation of the worm wheel 404 drives the adjustment shaft 401 to rotate, and the rotation of the adjustment shaft 401 changes The angle of the adjusting block 402 is adjusted, and the adjusting block 402 drives the installation block 403 to move, so that the installation block 403 adjusts the angle of the clamp accordingly, so that when the clamp is installed on the inclined electric pole, the clamp can also fit the electric pole tightly, thereby improving the stability of the installation and reducing the risk of the transformer body 2 shaking or loosening due to the inclination of the electric pole. At the same time, when the adjustment is completed, the hexagonal sleeve is inserted into the hexagonal block on the first screw rod 408, and the first screw rod 408 is rotated. When the first screw rod 408 rotates, the fixed block 406 is driven to slide through the thread, so that the fixed block 406 slides to engage with the fixed groove 407 in the adjusting shaft 401. Through the engagement of the fixed block 406 with the adjusting shaft 401, the force borne by the worm wheel 404 and the worm 405 can be effectively shared, so as to avoid the worm wheel 404 and the worm 405 from being aggravated by excessive force for a long time, thereby extending the service life of the transmission components and improving the reliability and stability.

[0043] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the cross arm 1 is provided with a lighting structure 8, and the lighting structure 8 includes a mounting frame 801 mounted on the cross arm 1 and a connecting plate 802 slidably connected to the mounting frame 801, a lighting lamp 803 is fixedly connected to the bottom of the connecting plate 802, a connecting shaft 804 is fixedly connected to the mounting frame 801, a rotating block 805 is rotatably connected to the connecting shaft 804, an iron block 806 is fixedly connected to the rotating block 805, a magnetic block 807 is installed on the connecting plate 802, a connecting frame 808 is installed between every two adjusting rods 301, and a photovoltaic panel 809 is installed on the connecting frame 808. When the installation is completed, the photovoltaic panel 809 can be installed between every two adjusting rods 301 through the connecting frame 808, and the photovoltaic panel 809 can also convert solar energy into The connecting plate 802 is converted into electrical energy to supply power to some electrical equipment of the entire device, and the connecting plate 802 is slid along the installation frame 801. When the connecting plate 802 slides to a certain position, the rotating block 805 drives the iron block 806 to rotate to the front of the magnetic block 807. At this time, the magnetic block 807 generates suction on the iron block 806, thereby improving the stability of the iron block 806 and preventing the rotating block 805 from shaking at will. Moreover, by having the iron block 806 in front of the connecting plate 802, the connecting plate 802 can be prevented from sliding off the installation frame 801, thereby ensuring the safe and stable installation of the lighting lamp 803. By setting the lighting lamp 803 at the bottom of the connecting plate 802, sufficient light source can be provided at night in remote areas to illuminate the surrounding environment. The light shines on the warning sign, which can significantly improve the warning effect and ensure the safety of personnel and the normal operation of equipment.

[0044] When the present invention is in use, when the transformer body 2 needs to be installed, the cross arm 1 is first placed between the two electric poles, and then the pressing shaft 307 is pressed downward. The pressing shaft 307 moves downward to drive the mounting plate 303 to slide. The sliding of the mounting plate 303 causes the first spring 306 to contract. At the same time, the mounting plate 303 drives the limiting block 304 to no longer engage with the limiting groove 305. When the pressing shaft 307 moves downward to a certain position, the pressing shaft 307 is driven to rotate with the help of the threaded sleeve 308, so that the threaded sleeve 308 and the threaded column 309 are threadedly matched. At this time, the mounting plate 303 will not slide upward under the action of the first spring 306, and the adjusting rod 301 and the cross arm 1 can slide relative to each other. When the adjusting rod 301 slides, it drives the anti-dropping block 302 to slide. The setting of the anti-dropping block 302 can prevent the adjusting rod 301 from slipping off the cross arm 1, avoiding the dangerous situation of accidental falling during installation or use. During the sliding process, the length of the adjusting rod 301 sliding out of the cross arm 1 can be flexibly controlled according to the actual distance between the two poles. At the same time, by observing the scale bar 310 on the adjusting rod 301, the sliding distance of the adjusting rods 301 on both sides can be kept consistent, ensuring the accuracy and balance of the installation. When the adjustment is completed, it is only necessary to make the threaded sleeve 308 no longer threaded with the threaded column 309, and the mounting plate 303 will be reset under the elastic force of the first spring 306, so that the limit block 304 is re-engaged with the limit groove 305, thereby completing the adjustment of the adjusting rod 301, and the adjusting rod 301 slides with the cross arm 1. Not only is it convenient to flexibly adjust the position of the clamp according to the different spacings between the poles to adapt to poles of various spacings, thereby improving the versatility of installation, but also during transportation, the adjusting rod 301 can be retracted into the cross arm 1, reducing the occupied space and facilitating transportation and storage. When the adjustment is completed, the transformer body 2 is installed on the cross arm 1, and then the transformer body 2 and the cross arm 1 are lifted together by the lifting equipment. After lifting to the specified position, carefully observe whether the pole is tilted. If the pole is tilted, the inner six sleeves can be inserted into the hexagonal block on the worm 405, and then the worm 405 can be rotated. When the worm 405 rotates, it drives the worm wheel 404 to rotate, and the rotation of the worm wheel 404 drives the adjusting shaft 401 to rotate, and the rotation of the adjusting shaft 401 changes The angle of the adjusting block 402 is driven by the adjusting block 402 to move the mounting block 403, so that the mounting block 403 adjusts the angle of the clamp accordingly, so that when the clamp is installed on a tilted electric pole, the clamp can also fit tightly to the electric pole, thereby improving the stability of the installation and reducing the risk of shaking or loosening of the transformer body 2 due to the tilt of the electric pole. At the same time, when the adjustment is completed, the hexagonal sleeve is inserted into the hexagonal block on the first screw rod 408, and the first screw rod 408 is rotated. When the first screw rod 408 rotates, the fixing block 406 is driven to slide through the thread, so that the fixing block 406 slides to engage with the fixing groove 407 in the adjusting shaft 401. By engaging the fixing block 406 with the adjusting shaft 401, the force borne by the worm wheel 404 and the worm 405 can be effectively shared.It prevents the worm wheel 404 and the worm 405 from being worn out due to long-term excessive force, prolongs the service life of the transmission parts, and improves reliability and stability;

[0045] When the installation is completed, the photovoltaic panel 809 can be installed between every two adjustment rods 301 through the connecting frame 808. The photovoltaic panel 809 can also convert solar energy into electrical energy to power some electrical equipment of the entire device. The connecting plate 802 is slid along the installation frame 801. When the connecting plate 802 slides to a certain position, the iron block 806 is driven to rotate to the front of the magnetic block 807 through the rotating block 805. At this time, the magnetic block 807 generates suction force on the iron block 806, thereby improving the stability of the iron block 806 and preventing the rotating block 805 from shaking at will. Moreover, the iron block 806 is in front of the connecting plate 802, which can prevent the connecting plate 802 from sliding off the installation frame 801, thereby ensuring the safe and stable installation of the lighting lamp 803. By setting the lighting lamp 803 at the bottom of the connecting plate 802, sufficient light source can be provided at night in remote areas to illuminate the surrounding environment. The light shines on the warning sign, which can significantly improve the warning effect and ensure the safety of personnel and the normal operation of equipment.

[0046] When lightning strikes, the lightning is attracted by the lightning rod 605, and the lightning is conducted along the conductive plug rod 604 and the conductive bushing 601 to the grounding wire 606, and finally the lightning is safely led into the ground through the grounding wire 606. The lead-out rotating rod 502 is made of insulating material, which can effectively prevent the lightning from being conducted to the transformer body 2, and provide reliable lightning protection for the transformer body 2, reduce the risk of damage to the transformer body 2 caused by lightning strikes, and ensure the stable operation of the power system. When it is necessary to inspect and repair the bushing and other components above the transformer body 2, the hydraulic rod 507 can be started, and the telescopic end of the hydraulic rod 507 drives the connecting rod when it is extended. 506 moves upward, the movement of the connecting rod 506 makes the resisting rod 707 no longer subject to the resisting force, at this time, the fixed rod 701 slides under the action of the second spring 710, and the fixed rod 701 slides with the guide rod 709 when sliding, and the setting of the guide rod 709 makes the sliding of the fixed rod 701 more stable and smooth, the fixed rod 701 drives the connecting block 702 to move, and the movement of the connecting block 702 drives the driving shaft 703 to roll in the driving groove 705, so that the driving block 704 drives the sliding rod 706 to move upward, and the sliding rod 706 on one side drives the sliding rod 706 on the other side to move upward synchronously through the fixing plate 708, and at the same time The fixed rod 701 is no longer engaged with the rotating rod 502, and the rack 505 is meshed with the gear 504. At this time, the hydraulic rod 507 continues to extend, driving the rack 505 to move upward, and the rack 505 drives the gear 504 and the fixed shaft 503 to rotate, so that the fixed shaft 503 drives the rainproof top plate 9 to rotate. After rotating ninety degrees, the rainproof top plate 9 no longer blocks the casing and other components, providing an open operating space for repairing the casing and other components, improving the repair efficiency and reducing the repair time. When the repair is completed, the hydraulic rod 507 is completely retracted to keep the four rotating rods 502 in a vertical state with the mounting frame 501. At this time, the hydraulic rod 507 is fully retracted to keep the four rotating rods 502 in a vertical state with the mounting frame 501. The connecting rod 506 at the telescopic end of the pressure rod 507 resists the movement of the resisting rod 707 downward, and the resisting rod 707 cooperates with the driving block 704 and other components to re-engage the fixing rod 701 and the rotating rod 502 to complete the fixation of the rotating rod 502. The rotating rod 502 is fixed by the fixing rod 701 to avoid the vibration during the operation of the transformer body 2 causing the meshing part of the gear 504 to be aggravated, resulting in the loosening of the rainproof top plate 9 and affecting its protective performance. The four rotating rods 502 are fixed by the fixing rod 701, which effectively disperses the influence of vibration, avoids the wear of the gear 504, and ensures that the rainproof top plate 9 always remains stable.
