Description

Technical Field

[0001] This invention relates to the technical field of outdoor power transformers, and in particular to an outdoor power transformer with lightning protection components. Background Technology

[0002] Outdoor power transformers are electrical equipment specifically designed for outdoor power supply systems. They are mainly used to convert high-voltage electrical energy into low-voltage electrical energy to achieve the transmission and distribution of electrical energy. The prior art patent number CN113782322B discloses an outdoor lightning protection power transformer, which can maximize the protection of the lightning rod from breaking due to strong winds during thunderstorms and ensure its own functional effect. However, when transformers are used outdoors, the large temperature difference between day and night causes condensation to easily form on the inner wall of the transformer body. This condensation flows directly down to the seals, aging them and shortening their lifespan. Furthermore, the heat dissipation fins on the sides of the transformer body are evenly spaced, making it difficult for external airflow to reach the fins in the middle, thus affecting the heat dissipation quality. Also, since the transformer is installed outdoors, falling objects from above can damage it. Therefore, there are areas for improvement. Summary of the Invention

[0003] To address the problems mentioned in the background section, the present invention provides an outdoor power transformer with lightning protection components.

[0004] The present invention provides an outdoor power transformer with lightning protection components, which adopts the following technical solution: An outdoor power transformer with lightning protection components, comprising: The transformer body has heat dissipation fins on its side. An air-guiding structure is provided in the heat dissipation fins to guide airflow to the heat dissipation fins for heat dissipation. An internal condensate drainage structure is installed inside the transformer body to guide the condensate flow from the inner wall of the transformer body. A protective structure is installed on the transformer body to provide shielding and protection above the transformer body; A lifting structure is installed on the transformer body to raise and lower the protective structure; A flipping structure is installed on the lifting structure, which works in conjunction with the lifting structure to lift, flip, and store the protective structure. A rotating positioning structure is installed on the protective structure to splice and protect the rotating protective structure. A pulling structure is located between the lifting structure and the air-expelling structure. During lifting, the pulling structure automatically pulls the air-expelling structure out from the heat dissipation fins.

[0005] As one embodiment, the air-expelling structure includes: Multiple air-guiding plates inserted into the heat dissipation fins; The length of each group of multiple air-guiding plates gradually increases from both sides to the middle.

[0006] As one implementation, the protective structure includes: A flip-up plate is installed at the corner of the side of the transformer body; A protective plate is installed at one end of the flip plate.

[0007] As one embodiment, the lifting structure includes: The guide plates are fastened to the side corners of the transformer body by bolts; A screw is rotatably connected between the inner walls of the upper and lower ends of the guide plate. A guide groove is opened on the guide plate, and a lifting seat is slidably arranged in the guide groove. A threaded groove is opened on the lifting seat for the screw to pass through. The motor is mounted at the bottom of the guide plate, and the top of the motor output shaft is connected to the screw.

[0008] As one embodiment, the flipping structure includes: Rotate the flip shaft that passes through the lifting seat, and one end of the flip plate is fixedly sleeved on the flip shaft; A gear is fixedly sleeved at one end of the flipping shaft, and a U-shaped strip is provided on the guide plate. The gear and the teeth on the U-shaped strip are meshed and connected.

[0009] As one embodiment, the rotary positioning structure includes: Rotate the rotating rod that passes through the other end of the flip plate; one end of the rotating rod is fastened to the protective plate by screws. The other end of the rotating rod is movably inserted into a square rod, the end face of which is square. A fixing strip is installed at the bottom of the rotating rod, and positioning rods are connected to both ends of the fixing strip. Four positioning slots are provided on the flip plate in a circular and equally angular arrangement. A spring is fitted onto the square rod, and a fixing bar and a rotating rod are respectively connected to the two ends of the spring.

[0010] As one embodiment, the pulling structure includes: A sliding groove is formed on the outer side of the transformer body, a slider is slidably arranged in the sliding groove, a lifting plate is arranged on the slider, and the lifting plate is installed at the bottom end of the air duct. A pull bar is connected to one side of the lifting seat, and one end of the pull bar extends to the bottom of the lifting plate. The lifting plate moves through the groove opened on the heat dissipation fins.

[0011] As one embodiment, the internal condensate drainage structure includes: A current-draining plate installed on the upper part of the inner wall of the transformer body, the current-draining plate being in the shape of an inverted "V"; There are four sets of guide plates on the inner wall of the transformer body. The guide plates are V-shaped and the top of the guide plates is inclined downward towards the inner wall of the transformer body. Each guide plate has a guide groove in the middle, and the multiple guide plates in each set are equally spaced. A water collection frame is installed along the inner edge of the lower part of the transformer body. A drain pipe is connected to the water collection frame, and a one-way valve is installed on the drain pipe.

[0012] In summary, the present invention has the following beneficial technical effects: This invention, by setting an internal condensate drainage structure, guides the condensate generated on the inner wall of the transformer body to drain out of the transformer in environments with large day-night temperature differences, thus preventing the condensate from directly penetrating the seals and shortening the service life of the internal seals of the transformer body. This invention incorporates a protective structure, a lifting structure, a flipping structure, and a rotation positioning structure. The lifting and flipping structures automatically lift and flip the protective structure to a position directly above the transformer body. The rotation positioning structure then rotates and splices the four protective plates of the protective structure together for positioning. This allows the spliced ​​protective plates to provide protection above the transformer body. During transformer transport, the protective structure can be moved from above the transformer body to the side of the transformer body, facilitating the transport of the transformer body. This invention utilizes an air-guiding structure and a pulling structure. When the lifting structure raises the protective structure, the pulling structure automatically moves the air-guiding structure out from inside the heat dissipation fins. This allows for better airflow to be directed to each heat dissipation fin to dissipate heat and improve the heat dissipation quality. Attached Figure Description

[0015] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0016] This invention discloses an outdoor power transformer with lightning protection components. (Refer to...) Figures 1-9 An outdoor power transformer with lightning protection components includes: a transformer body 1, with heat dissipation fins 2 on the side of the transformer body 1; an air-guiding structure disposed in the heat dissipation fins 2 to guide airflow to the heat dissipation fins 2 for heat dissipation; an internal condensate drainage structure disposed inside the transformer body 1 to guide condensate from the inner wall of the transformer body 1; a protective structure disposed on the transformer body 1 to provide shielding protection above the transformer body 1; a lifting structure disposed on the transformer body 1 to lift and lower the protective structure; a flipping structure disposed on the lifting structure to cooperate with the lifting structure to lift, flip, and store the protective structure; a rotation positioning structure disposed on the protective structure to splice and protect the rotated protective structure; and a pulling structure disposed between the lifting structure and the air-guiding structure to automatically pull the air-guiding structure out from the heat dissipation fins 2 during lifting and lowering.

[0017] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 The air-guiding structure includes: multiple air-guiding plates 22 inserted into the heat dissipation fins 2; the length of each group of multiple air-guiding plates 22 gradually increases from both sides to the middle; the protective structure includes: a flip-up plate 6 set at the side corner of the transformer body 1; a protective plate 7 is set at one end of the flip-up plate 6; The lifting structure includes: a guide plate 9 fastened to the side corner of the transformer body 1 by bolts; a screw 10 rotatably connected between the inner walls of the upper and lower ends of the guide plate 9; a guide groove 12 is opened on the guide plate 9; a lifting seat 11 is slidably arranged in the guide groove 12; a threaded groove is opened on the lifting seat 11 for the screw 10 to pass through; a motor 8 is installed at the bottom of the guide plate 9; and the top end of the output shaft of the motor 8 is connected to the screw 10. The flipping structure includes: a flipping shaft 13 that rotates through the lifting seat 11; one end of the flipping plate 6 is fixedly sleeved on the flipping shaft 13; a gear 15 is fixedly sleeved on one end of the flipping shaft 13; a U-shaped strip 16 is provided on the guide plate 9; and the gear 15 and the teeth on the U-shaped strip 16 are meshed and connected. The rotary positioning structure includes: a rotating rod 17 that rotates through the other end of the flip plate 6, one end of which is fastened to the protective plate 7 by screws; the other end of the rotating rod 17 is movably inserted into a square rod, the end face of which is square; a fixing strip 18 is installed at the bottom of the rotating rod 17, and positioning rods 20 are connected to both ends of the fixing strip 18; four positioning slots 21 are provided on the flip plate 6 in a circular and equidistant manner; a spring 19 is sleeved on the square rod, and the two ends of the spring 19 are respectively connected to the fixing strip 18 and the rotating rod 17. The pulling structure includes: a slide groove on the outer side of the transformer body 1, a slider 24 slidingly disposed in the slide groove, a lifting plate 23 disposed on the slider 24, and the lifting plate 23 being installed at the bottom of the air duct 22; a pulling strip 26 is connected to one side of the lifting seat 11, one end of the pulling strip 26 extends to the bottom of the lifting plate 23, and the lifting plate 23 moves through the groove 25 on the heat dissipation fin 2. After the transformer body 1 is installed, when protection is needed above the transformer body 1, the motor 8 on the guide plate 9 is started to drive the screw 10 to rotate. The lifting seat 11 moves upward on the rotating screw 10. The guide groove 12 guides the lifting seat 11. During the upward movement of the lifting seat 11, the rolling of the gear 15 on the U-shaped bar 16 drives the flipping shaft 13 and the flipping plate 6 to rotate as a whole. The flipping plate 6 flips to the vertical upward position, lifting the protective plate 7. When the protective plate 7 moves to the protective position, the fixing bar 18 is used to pull one end of the positioning rod 20 out of the positioning groove 21, stretching the spring 19 and releasing the positioning of the rotating rod 17 on the flipping plate 6. Then, with the rotating rod 17 as the axis, Rotate the protective plate 7 so that the four protective plates 7 are flipped and spliced ​​together above the transformer body 1, providing protection above the transformer body 1. Then, loosen the fixing strip 18 and use the elastic force of the spring 19 to pull one end of the fixing strip 18 and the other end of the positioning rod 20 back into the corresponding positioning slot 21 to position the spliced ​​protective plate 7. At the same time, the lifting seat 11 moves upward, which drives the pulling strip 26 to move upward. The pulling strip 26 pulls the lifting plate 23 to move upward, removing the air guide plate 22 from the heat dissipation fin 2. In this way, the removed air guide plate 22 guides the airflow to each heat dissipation fin 2 to better remove the heat from the heat dissipation fin 2 and improve the heat dissipation quality of the transformer body 1.

[0018] See Figure 7 and Figure 8 The internal condensate diversion structure includes: a diversion plate 5 installed on the upper part of the inner wall of the transformer body 1, the diversion plate 5 being inverted "V" shape; four sets of diversion plates 3 on the inner wall of the transformer body 1, the diversion plates 3 being in "V" shape, the top of the diversion plates 3 being inclined downward towards the side closer to the inner wall of the transformer body 1, and a diversion groove 4 being opened in the middle of each diversion plate 3, with equal spacing between each set of multiple diversion plates 3; A water collection frame 14 is installed along the inner edge of the lower part of the transformer body 1. A drain pipe is connected to the water collection frame 14, and a one-way valve is installed on the drain pipe. In environments with large day and night temperatures, the condensate on the inner wall of the transformer body 1 is guided by the diversion plate 5 to the guide plate 3. The condensate on the inner side wall of the transformer body 1 is guided by the guide plate 3 and the guide groove 4 to the water collection frame 14, and then discharged from the transformer body 1 through the drain pipe on the water collection frame 14. This avoids the condensate from submerging the seals of the transformer body 1, which would lead to aging of the seals and a shortened service life.

[0019] The implementation principle of an outdoor power transformer with lightning protection components according to an embodiment of the present invention is as follows: After the transformer body 1 is installed, when protection is needed above the transformer body 1, the motor 8 on the guide plate 9 is started to drive the screw 10 to rotate. The lifting seat 11 moves upward on the rotating screw 10. The guide groove 12 guides the lifting seat 11. During the upward movement of the lifting seat 11, the rolling of the gear 15 on the U-shaped strip 16 drives the flipping shaft 13 and the flipping plate 6 to rotate as a whole. The flipping plate 6 flips to a vertically upward state, lifting the protective plate 7. When the protective plate 7 moves to the protective position, the fixing strip 18 is used to pull one end of the positioning rod 20 out of the positioning groove 21, stretching the spring 19 and releasing the positioning of the rotating rod 17 on the flipping plate 6. Then, the protective plate 7 is rotated around the rotating rod 17 as the axis, so that the four protective plates 7 are flipped and spliced ​​together above the transformer body 1, providing protection above the transformer body 1. After loosening the fixing strip 18, the spring force of the spring 19 is used to pull one end of the fixing strip 18, the positioning rod 20, back into the corresponding positioning groove 21 to position the spliced ​​protective plate 7. At the same time, the lifting seat 11 moves upward, which drives the pulling strip 26 to move upward. The pulling strip 26 pulls the lifting plate 23 to move upward, removing the air guide plate 22 from the heat dissipation fin 2. In this way, the removed air guide plate 22 guides the airflow to each heat dissipation fin 2 to better remove the heat from the heat dissipation fin 2, improving the heat dissipation quality of the transformer body 1. In environments with large day and night temperatures, the condensate on the inner wall of the transformer body 1 is guided by the diversion plate 5 to the guide plate 3. The condensate on the inner side wall of the transformer body 1 is guided by the guide plate 3 and the guide groove 4 to the water collection frame 14, and discharged from the transformer body 1 by the drain pipe on the water collection frame 14. This avoids the condensate from submerging the seals of the transformer body 1, which would cause the seals to age and shorten their service life.

[0020] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
