Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to an outdoor lightning protection transformer. Background Technology

[0002] A transformer is a static electrical device that converts electrical energy based on the principle of electromagnetic induction. It is mainly used in AC circuits for voltage level transformation, current regulation, and impedance matching. Its core structure consists of an iron core and windings. The primary winding, connected to the input power supply, generates an alternating magnetic field, while the secondary winding induces an electromotive force through magnetic coupling, thus transferring energy. Depending on the turns ratio, transformers can step up or step down voltage to meet the needs of various scenarios, including power transmission, industrial power consumption, and power supply for electronic equipment. Modern transformers use high-permeability silicon steel laminated cores to reduce eddy current losses, and the windings use copper or aluminum wires. They are also equipped with insulating oil, radiators, and other devices to ensure safe operation. In power systems, transformers play a crucial role, stepping up voltage to reduce line losses during long-distance transmission and stepping down voltage to the appropriate level for the user in the distribution stage.

[0003] During thunderstorms, if transformers cannot dissipate internal heat in time, the operating temperature of the equipment may continue to rise, leading to a series of safety hazards. Since lightning activity may be accompanied by grid voltage fluctuations or transient overvoltages, the transformer load current increases, which intensifies winding and core losses and generates more heat. If the cooling system (such as oil circulation, cooling fans, etc.) becomes less efficient due to high ambient humidity, poor ventilation, or rainwater intrusion, the heat accumulation will accelerate the aging of the insulating oil, reduce its dielectric strength and cooling performance, and in severe cases may cause partial discharge or insulation breakdown. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: an outdoor lightning protection transformer, including a protection box and a base fixedly connected to the lower surface of the protection box. By setting the base, the protection box can be conveniently installed in a designated location. Lightning protection mechanisms are used to guide lightning strikes through the power transmission line into the ground. The main function of these mechanisms is to effectively protect transformers from damage caused by lightning overvoltages, ensuring the safe and stable operation of the power system. In thunderstorms, lightning may enter the transformer through the transmission line, causing insulation breakdown, equipment damage, or even power outages. Lightning protection mechanisms can limit lightning overvoltages to a safe range, quickly discharge lightning current, reduce the overvoltage amplitude, and prevent dangerous high potentials from being generated on the equipment by lightning current. The rotating mechanism is used to convert wind power into power. By setting the rotating mechanism, natural wind can be used to generate a rotation effect in the inner cavity of the protective box during thunderstorms, thereby driving the heat dissipation mechanism to start working. The heat dissipation mechanism is used to dissipate the heat generated by the transformer during operation. By setting up the heat dissipation mechanism, when the rotating mechanism rotates due to natural wind, the mineral oil stored in the inner cavity of the protection box is agitated.

[0014] This invention provides an outdoor lightning protection transformer. It has the following beneficial effects: I. This outdoor lightning protection transformer, by setting up a lightning protection mechanism, mainly serves to effectively protect the transformer from damage caused by lightning overvoltage, ensuring the safe and stable operation of the power system. In thunderstorms, lightning may enter the transformer through the transmission line, causing insulation breakdown, equipment damage, or even power outages.

[0016] Third, this outdoor lightning protection transformer, by setting up a heat dissipation mechanism, can agitate the mineral oil stored in the inner cavity of the protection box when the rotating mechanism rotates due to natural wind. In the process of the mineral oil flowing in the inner cavity of the protection box, the heat generated by the transformer operation is carried away, thereby completing the heat dissipation work.

[0017] IV. This outdoor lightning protection transformer, by setting threaded columns with spiral grooves on the outer surface, can generate mineral oil flow in the inner cavity of the protection box when the rotating rod drives the threaded columns to rotate. By setting metal heat dissipation pipes, the heat inside the mineral oil can be quickly dissipated by taking advantage of the fast heat conduction of metal.

[0018] V. This outdoor lightning protection transformer utilizes a nickel-titanium alloy spring. Taking advantage of its properties, when lightning strikes, the nickel-titanium alloy spring generates heat due to the current, causing it to return to its original shape and extend. By incorporating a first spring, the circuit remains connected even when the sliding terminal moves up and down. Furthermore, the nickel-titanium alloy spring can monitor the temperature of the outer surface of the protection box, and will deform even when the temperature of the protection box casing is too high.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] like Figures 1-11 As shown, the present invention provides a technical solution: an outdoor lightning protection transformer, including a protection box 2 and a base 1 fixedly connected to the lower surface of the protection box 2. By setting the base 1, the protection box 2 can be conveniently installed in a designated position. Lightning protection mechanism 5 is used to guide lightning from the penetrating device to the ground. By setting up lightning protection mechanism 5, the main function is to effectively protect the transformer from damage caused by lightning overvoltage and ensure the safe and stable operation of the power system. In thunderstorms, the generated lightning may enter the transformer through the transmission line, causing insulation breakdown, equipment damage, or even power outages. Lightning protection mechanism 5 can limit the lightning overvoltage to a safe range, quickly discharge the lightning current, reduce the overvoltage amplitude, and prevent the lightning current from generating dangerous high potentials on the equipment. Rotating mechanism 6 is used to convert wind power into power. By setting rotating mechanism 6, natural wind can be used to generate a rotation effect in the inner cavity of the protective box 2 during thunderstorms, thereby driving the heat dissipation mechanism 7 to start working. The heat dissipation mechanism 7 is used to dissipate the heat generated by the transformer during operation. By setting the heat dissipation mechanism 7, when the rotating mechanism 6 rotates due to natural wind, the mineral oil stored in the inner cavity of the protection box 2 is stirred, and the mineral oil carries away the heat generated by the transformer during the flow of the mineral oil in the inner cavity of the protection box 2, thereby completing the heat dissipation work. The lightning protection mechanism 5 is fixedly connected to the outer side of the protection box 2, the rotating mechanism 6 is located directly above the protection box 2, and the heat dissipation mechanism 7 is located in the inner cavity of the protection box 2. The heat dissipation mechanism 7 includes a side plate 71, which is symmetrically fixedly connected to the opening on the outer side of the protective box 2. A rolling bearing 75 is fixedly connected to the inner surface of the side plate 71, and a rotating rod 76 is fixedly connected to the inner ring of the rolling bearing 75. A threaded column 78 is fixedly connected to the end of the rotating rod 76. A metal heat dissipation pipe 74 penetrates the outer surface of the side plate 71. By setting the side plate 71, the opening on the outer side of the protective box 2 can be sealed, thereby preventing the mineral oil in the inner cavity of the protective box 2 from leaking. By setting the rolling bearing 75, the rotating rod 76 can rotate more stably. By setting the threaded column 78, the outer surface of which has a spiral groove, the threaded column 78 can generate mineral oil flow in the inner cavity of the protective box 2 when the rotating rod 76 drives the threaded column 78 to rotate. By setting the metal heat dissipation pipe 74, the heat inside the mineral oil can be quickly dissipated by utilizing the fast thermal conductivity of metal.

[0023] A fixing frame 8 is fixedly connected to the bottom surface of the inner cavity of the protective box 2. A winding coil 9 is fixedly connected to the upper surface of the fixing frame 8. A connecting rod 10 is provided on the upper surface of the winding coil 9. There are four connecting rods 10, and the four connecting rods 10 are evenly distributed. The top of the connecting rod 10 is fixedly connected to a high voltage output terminal 11 and a low voltage output terminal 12, respectively. By setting the fixing frame 8, the winding coil 9 can be supported, so that the winding coil 9 can be fixed in the middle of the inner cavity of the protective box 2, thereby allowing the mineral oil to fully contact the winding coil 9. By setting the connecting rod 10, the high voltage output terminal 11 and the low voltage output terminal 12 can be connected to the winding coil 9.

[0024] The lightning protection mechanism 5 includes a fixing plate 51, which is fixedly connected to the outer side of the protection box 2. A track box 52 is fixedly connected to the outer surface of the fixing plate 51, and a support plate 55 is fixedly connected to the outer surface of the track box 52. A surge arrester 56 is fixedly connected to the end of the support plate 55. A first terminal block 53 is fixedly connected to the outer surface of the fixing plate 51, and a grounding wire 54 is connected to the lower surface of the first terminal block 53. By setting the support plate 55, the surge arrester 56 can be supported, thereby placing the surge arrester 56 at the lowest position of the transformer. The track box 52 is positioned at a high point, ensuring that when lightning strikes, it first contacts the surge arrester 56. By installing the surge arrester 56, the lightning current can be quickly discharged, reducing the overvoltage amplitude. The first terminal block 53 and grounding wire 54 ensure that the lightning current is smoothly conducted to the ground, preventing dangerous high potentials from being generated on the equipment. A second terminal block 58 is fixedly connected to the upper surface of the track box 52, and a wire 57 is fixedly connected to the upper surface of the second terminal block 58. The top end of the wire 57 is connected to the surge arrester 56. A sliding connection is established within the inner cavity of the track box 52. A sliding terminal 510 is connected, with a nickel-titanium alloy spring 59 fixedly connected to its top end. The top end of the nickel-titanium alloy spring 59 is fixedly connected to the output end of a second terminal block 58. A first spring 511 is fixedly connected to the bottom end of the sliding terminal 510, and the bottom end of the first spring 511 is fixedly connected to the upper surface of a first terminal block 53. By setting the second terminal block 58 and the wire 57, the current attracted by the surge arrester 56 can be transferred to the inside of the nickel-titanium alloy spring 59, and then through the sliding terminal 510 and the first spring 51... The current is transmitted to the first terminal block 53 and finally flows into the ground through the grounding wire 54. By setting a nickel-titanium alloy spring 59, its characteristics can be utilized. When lightning strikes, the nickel-titanium alloy spring 59 will generate heat due to the current, and then return to its original shape and stretch. By setting a first spring 511, the circuit can still be kept connected when the sliding terminal 510 moves up and down. In addition, the nickel-titanium alloy spring 59 can monitor the temperature of the outer surface of the protection box 2. When the temperature of the outer shell of the protection box 2 is too high, it will still deform.

[0025] A sliding bracket 512 is fixedly connected to the upper surface of the sliding terminal 510. A baffle plate 513 is fixedly connected to the top of the sliding bracket 512. A soft pad 514 is fixedly connected to the outer surface of the baffle plate 513. A limit ring 3 is fixedly connected to the opening of the protective box 2. A top cover 4 is fixedly connected to the outer surfaces of the high-voltage output terminal 11 and the low-voltage output terminal 12. The rotating mechanism 6 includes a rotating ring 61, which is rotatably connected between the limit ring 3 and the top cover 4. By setting the baffle plate 513 and the soft pad 514, the rotating mechanism 6 can be blocked when the nickel-titanium alloy spring 59 is not deformed, thus preventing the rotating mechanism 6 from rotating. However, when the nickel-titanium alloy spring 59 deforms... When the time comes, the barrier plate 513 and the soft pad 514 move downwards, thus no longer blocking the rotating mechanism 6. By setting the limiting ring 3 and the top cover 4, the rotating ring 61 can be limited, so that the rotating ring 61 can generate stable rotation between them. The outer surface of the rotating ring 61 is fixedly connected with a fan plate 63. There are several fan plates 63, and the several fan plates 63 are evenly distributed. The fan plates 63 are pressed and adapted to the outer surface of the soft pad 514. The inner ring of the rotating ring 61 is fixedly connected with a toothed ring 62. By setting the fan plates 63, when encountering natural wind, the fan plates 63 can be pushed, thereby causing the rotating ring 61 to rotate between the limiting ring 3 and the top cover 4, and thus causing the toothed ring 62 to rotate.

[0026] A gear 77 is fixedly connected to the top of the rotating rod 76. The gear 77 meshes with the gear ring 62. Several metal heat dissipation pipes 74 are evenly distributed. A flow guide box 73 is fixedly connected to the inner surface of the side plate 71. By setting the gear 77, when the gear ring 62 rotates with the rotating ring 61, the gear ring 62 meshes with the gear 77, thereby causing the gear 77 to drive the rotating rod 76 to rotate. By setting the flow guide box 73, the mineral oil flowing downwards in the inner cavity of the protective box 2 can be guided, allowing the mineral oil to enter the inner cavity of the metal heat dissipation pipe 74 through the bottom of the flow guide box 73, and then flow from the bottom to the top of the metal heat dissipation pipe 74, ultimately returning to its original state. The fluid flows into the inner cavity of the protective box 2. An arc-shaped box 72 extends through the outer side of the side plate 71. A first track groove 79 is fixedly connected to the inner wall of the arc-shaped box 72. A sliding sleeve 710 is slidably connected to the inner cavity of the first track groove 79. A second spring 711 is fixedly connected to the upper surface of the sliding sleeve 710. The top end of the second spring 711 is fixedly connected to the top surface of the inner cavity of the arc-shaped box 72. By setting the first track groove 79, the sliding sleeve 710 can be limited, allowing it to move vertically up and down within the inner cavity of the first track groove 79. By setting the second spring 711, after the first sliding sleeve 710 has moved downwards to the bottom and is no longer subjected to downward pressure, the second spring 711 can then... Pulling 710 causes the sliding sleeve 710 to return to its original position. A limiting tube 712 is fixedly connected to the inner cavity of the sliding sleeve 710. A limiting block 713 is fixedly connected to the end of the limiting tube 712. A rotating sleeve 714 is rotatably connected to the outer surface of the limiting block 713. The rotating sleeve 714 is frictionally fitted with the groove of the threaded post 78. A first strong magnet 715 is slidably connected to the inner cavity of the limiting tube 712. A third spring 716 is fixedly connected to the end of the first strong magnet 715. The end of the third spring 716 is fixedly connected to the surface of the limiting block 713. By setting the limiting tube 712, the first strong magnet 715 can be limited, creating a distance between the first strong magnet 715 and the sliding sleeve 710. The change occurs when the sliding sleeve 710 continues to move downwards and disengages from the first track groove 79, causing the sliding sleeve 710 and the limiting tube 712 to move laterally. This prevents the sliding sleeve 710 and the rotating sleeve 714 from contacting the groove of the threaded column 78. Then, under the elastic potential energy of the second spring 711, the sliding sleeve 710 moves upwards. By setting a limiting block 713, the rotating sleeve 714 can be limited, causing it to rotate on the outer surface of the limiting block 713. When the threaded column 78 rotates, the rotating sleeve 714 is subjected to a downward compressive force. The outer surface of the arc-shaped box 72 is fixedly connected to a second track groove 717, and a second strong magnet 718 is slidably connected to the inner cavity of the second track groove 717.The second strong magnet 718 attracts the first strong magnet 715. A scraper 719 is fixedly connected to the outer surface of the second strong magnet 718. The scraper 719 is frictionally adapted to the outer surface of the metal heat sink 74. By setting a second track groove 717, the second strong magnet 718 can be limited, allowing it to move vertically up and down within the inner cavity of the second track groove 717. By setting the first strong magnet 715 and the second strong magnet 718, the up and down movement of the first strong magnet 715 drives the second strong magnet 718 to move up and down as well. By setting the scraper 719, the up and down movement of the second strong magnet 718 allows the scraper 719 to remove dust or dirt adhering to the outer surface of the metal heat sink 74, thereby ensuring that the metal heat sink 74 is in contact with cold air and achieving an increased heat dissipation effect.

[0027] Working principle: During thunderstorms, when lightning approaches the transformer, it is attracted by the surge arrester 56 and flows through the conductor 57 and the second terminal block 58 to the nickel-titanium alloy spring 59. The lightning then flows through the sliding terminal 510 to the first spring 511, and finally through the first terminal block 53 and the grounding wire 54 to the ground, thus protecting the transformer. When high-voltage current flows, the temperature of the nickel-titanium alloy spring 59 rises, causing it to deform and elongate. When 9 extends, the sliding terminal 510 moves downward within the inner cavity of the track box 52, thereby removing the obstruction between the baffle plate 513 and the pad 514. Under the influence of natural wind, the wind blows onto the outer surface of the fan plate 63, causing it to be compressed. This causes the rotating ring 61 to drive the gear ring 62 to rotate between the limiting ring 3 and the top cover 4. When the gear ring 62 rotates, it meshes with the gear 77, causing the rotating rod 76 to drive the threaded column 78 to rotate. When the threaded column 78 rotates, it causes the inner cavity of the protective box 2 to... The mineral oil flows downwards and enters the inner cavity of the guide box 73, thus allowing the mineral oil to flow from the bottom to the top of the metal heat sink 74. When the metal heat sink 74 comes into contact with the air, it dissipates the heat in the mineral oil into the air, thereby lowering the temperature of the mineral oil. During the rotation of the threaded column 78, the rotating sleeve 714 contacts the groove of the threaded column 78, causing the sliding sleeve 710 to move downwards in the inner cavity of the first track groove 79. When the first strong magnet 715 moves downwards, it drives the second strong magnet 718 to produce... The sliding sleeve 710 moves downward, eventually causing the scraper 719 to scrape away the dust or dirt attached to the outer surface of the metal heat sink 74, thereby ensuring that the metal heat sink 74 is in contact with the cold air and achieving the effect of increasing heat dissipation. Then, as the sliding sleeve 710 continues to move downward and disengages from the first track groove 79, the sliding sleeve 710 and the limiting tube 712 move laterally, thereby causing the sliding sleeve 710 and the rotating sleeve 714 to no longer contact the groove of the threaded column 78. Then, under the action of the elastic potential energy of the second spring 711, the sliding sleeve 710 moves upward.
