[0002] In the power system, oil-immersed transformers are key equipment, and their operating status directly affects the stability and security of the entire power grid.

[0003] In existing related technologies, during the operation of oil-immersed transformers, dust, stains and moisture often accumulate on their surfaces due to factors such as environmental humidity, temperature changes and their own heat dissipation.

[0037] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0038] An active moisture-proof oil-immersed transformer according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figures 1 to 12As shown, an embodiment of the present invention provides an active moisture-proof oil-immersed transformer, comprising: a fixed protective assembly 8, comprising a compacting plate 9, a bidirectional motor 10 and a reciprocating insulating dust removal plate 13, the bidirectional motor 10 being arranged at the bottom of the compacting plate 9, a mounting frame 11 being provided on the left and right sides of the bidirectional motor 10, a through slot being provided inside the mounting frame 11 on each side, a moving block 14 being provided inside the through slot, the reciprocating insulating dust removal plate 13 being provided at the bottom of the moving block 14, an oil-immersed transformer body 35 being provided below the reciprocating insulating dust removal plate 13, a driving rod 12 being provided at the working ends on both sides of the bidirectional motor 10, one end of each driving rod 12 being respectively passed through the outer wall of the mounting frame 11 and connected to the moving block 14;

[0040] A delivery pipe 33 is provided on both sides of the top surface of the oil-immersed transformer body 35. An active dehumidification airflow guide assembly 1 is provided inside the delivery pipe 33. The active dehumidification airflow guide assembly 1 includes a guide rod 3, a guide sleeve shaft 4, a guide blade 5 and a cooling rod 7. The guide sleeve shaft 4 is sleeved on the outer wall of the guide rod 3, the guide blade 5 is provided on the outside of the guide sleeve shaft 4, and the cooling rod 7 is provided inside the guide sleeve shaft 4.

[0041] In a specific application of the embodiment of the present invention, the fixed protective assembly 8 consists of a compacting plate 9, a bidirectional motor 1, a mounting frame 11, a moving block 14, and a reciprocating insulating dust removal plate 13. The bidirectional motor 1 is mounted on the bottom of the compacting plate 9. The mounting frames 11 on the left and right sides are each provided with a through slot, in which a slidable moving block 14 is provided. The two working ends of the bidirectional motor 1 are respectively connected to two driving rods 12, which pass through the outer wall of the mounting frame 11 and are connected to the moving block 14. When the bidirectional motor 1 is started, the driving rod 12 drives the moving block 14 to move back and forth in the through slot, thereby driving the reciprocating insulating dust removal plate 13 to perform a reciprocating dust removal action above the oil-immersed transformer body 35, effectively removing dust and impurities from the top surface of the transformer and keeping the transformer surface clean.

[0042] The active dehumidification airflow guide assembly 1 is disposed within the delivery pipes 33 on both sides of the top surface of the oil-immersed transformer body 35. The active dehumidification airflow guide assembly 1 comprises a guide rod 3, a guide sleeve 4, guide vanes 5, and a cooling rod 7. The guide sleeve 4 is sleeved on the outer wall of the guide rod 3 and can rotate freely along the guide rod 3. The guide vanes 5 are fixed to the outside of the guide sleeve 4. When airflow is generated inside the transformer, the guide vanes 5 can guide the airflow in a specific direction, enhancing the dehumidification effect of the airflow. Simultaneously, the cooling rod 7 is disposed within the guide sleeve 4. By absorbing and dispersing the heat generated during transformer operation, it further reduces the temperature and humidity inside the transformer, achieving the purpose of active dehumidification.

[0043] When the oil-immersed transformer begins operation, the bidirectional motor 1 of the fixed protection assembly 8 starts first, driving the reciprocating insulating dust removal plate 13 to perform a reciprocating dust removal operation above the transformer body. Subsequently, the active dehumidification airflow guide assembly 1 begins to operate. The guide blades 5 rotate under the influence of the airflow, guiding the airflow in a specific direction. At the same time, the cooling rod 7 absorbs and disperses the heat inside the transformer. Through the coordinated operation of the fixed protection assembly and the active dehumidification airflow guide assembly, the oil-immersed transformer can effectively reduce the internal humidity and temperature, maintaining the transformer's stable operation.

[0044] In a possible embodiment, the active moisture-proof oil-immersed transformer further includes: a working box 18, a limiting groove 26 is opened inside the working box 18, and there are two groups of limiting grooves 26. An electric propeller 30 is provided inside the two groups of limiting grooves 26. The working end of the electric propeller 30 is provided with a connecting rod 31, and the other end of the connecting rod 31 is provided with a bearing frame 29. The four corners of the bottom surface of the working box 18 are respectively provided with support columns 20, and the bottoms of the four support columns 20 are provided with wear-resistant pads 21, and the bottoms of the wear-resistant pads 21 are provided with anti-slip grooves.

[0045] The oil-immersed transformer body 35 is arranged inside the two sets of supporting frames 29. The outer wall of the supporting frame 29 is provided with an electric retractor 27. The working end of the electric retractor 27 is provided with an L-shaped control rod 28. The output end of the L-shaped control rod 28 is provided on the outer wall of the compacting plate 9. The fixed protective assembly 8 is provided above the oil-immersed transformer body 35.

[0046] In a specific application of the embodiment of the present invention, a limiting slot 26 is provided inside the working box 18 for installing and fixing the electric propeller 30. The electric propeller 30 pushes the supporting frame 29 to move within the limiting slot 26 through the connecting rod 31 connected to its working end. The supporting frame 29 is used to support the oil-immersed transformer body 35 to ensure its stable placement. At the same time, the outer wall of the supporting frame 29 is provided with an electric telescoping device 27. The working end of the electric telescoping device 27 is connected to an L-shaped control rod 28. The output end of the L-shaped control rod 28 is provided on the outer wall of the compaction plate 9. Through the telescopic action of the electric telescoping device 27, the position of the compaction plate 9 can be flexibly adjusted, thereby achieving stable compaction and protection of the oil-immersed transformer body 35. Support columns 20 are provided at the four corners of the bottom surface of the working box 18. The bottom of the support column 20 is provided with a wear-resistant pad 21. The bottom of the wear-resistant pad 21 is also provided with anti-slip grooves to enhance the friction between the transformer and the ground and prevent the transformer from sliding or tilting during operation.

[0047] For active moisture protection, the oil-immersed transformer is also equipped with a fixed protective assembly 8, located above the oil-immersed transformer body 35. This assembly, through its internal bidirectional motor 10 and reciprocating insulating dust removal plates 13, actively removes moisture and dust from the transformer's interior. Furthermore, delivery pipes 33 are located on both sides of the top surface of the oil-immersed transformer body 35. Within these pipes 33 is an active moisture-removing airflow guide assembly 1, which guides airflow and further reduces humidity within the transformer.

[0048] When the oil-immersed transformer starts working, the electric propeller 30 is first used to push the supporting frame 29 and the oil-immersed transformer body 35 to the specified position. Then, the electric telescoping device 27 is started, and the position of the compacting plate 9 is adjusted by the L-shaped control rod 28 to firmly compact the transformer body. At this time, the fixed protection component 8 starts working, and the reciprocating insulating dust removal plate 13 is driven by the bidirectional motor 10 to perform reciprocating dust removal. At the same time, the active dehumidification airflow guide component 1 guides the airflow to realize the active moisture-proof function of the transformer. Finally, the transformer body starts to operate normally, and the support column 20 and the wear-resistant pad 21 provide firm support to ensure that the transformer can still operate efficiently and stably in a complex environment.

[0049] In one embodiment, filter plates 2 are respectively provided at both ends of the guide rod 3, a first damping rod 6 is provided on the outer wall of the guide sleeve 4, the other end of the first damping rod 6 is provided on the outer wall of the filter plate 2, the inner wall of the guide sleeve 4 is attached to the outer wall of the guide rod 3, the moving block 14 is provided inside the mounting frame 11, the driving rod 12 passes through the outer wall of the mounting frame 11 and is connected to the moving block 14, a second damping rod 15 is provided on the other side of the outer wall of the moving block 14, and buffer rods 17 are respectively provided at both ends of the bottom of the compacting plate 9, and a buffer plate 16 is provided at the bottom of the buffer rod 17.

[0050] In specific applications of this embodiment of the present invention, filter plates 2 are provided at each end of the guide rod 3. These filter plates 2 effectively prevent external impurities and moisture from entering the transformer interior. The outer wall of the guide rod 3 closely fits the inner wall of the guide sleeve 4, allowing the guide sleeve 4 to freely rotate on the guide rod 3 while simultaneously driving the guide vanes 5 on its outer side to guide the airflow. To increase the stability of the guide sleeve 4 during rotation, a first damping rod 6 is positioned between the outer wall of the guide sleeve 4 and the outer wall of the filter plates 2. The first damping rod 6 provides appropriate resistance to prevent the guide sleeve 4 from shaking or deflecting during rotation, thereby ensuring the accuracy and stability of the airflow guidance.

[0051] Inside the mounting frame 11, the moving block 14 is used to connect the drive rod 12 and the reciprocating insulating dust removal plate 13. The drive rod 12 passes through the outer wall of the mounting frame 11 and is connected to the moving block 14. When the bidirectional motor 10 is started, the drive rod 12 will drive the moving block 14 to move back and forth in the mounting frame 11, thereby driving the reciprocating insulating dust removal plate 13 to perform dust removal. In order to increase the stability of the moving block 14 during movement, a second damping rod 15 is provided on the other side of the outer wall of the moving block 14, forming a damping connection with the inner wall of the mounting frame 11. At the bottom of the compacting plate 9, the buffer rod 17 is connected to the buffer plate 16. When the transformer is subjected to external shock or vibration, the buffer rod 17 and the buffer plate 16 can jointly absorb and disperse these impact forces, thereby protecting the components inside the transformer from damage. At the same time, the setting of the buffer rod 17 and the buffer plate 16 can also increase the overall stability and durability of the transformer.

[0052] When an oil-immersed transformer begins operation, filter plate 2 first blocks external impurities and moisture from entering the transformer. Subsequently, bidirectional motor 10 activates, driving drive rod 12 and movable block 14 to reciprocate within mounting frame 11, thereby driving reciprocating insulating dust removal plate 13 to remove dust. Simultaneously, guide sleeve 4 rotates freely on guide rod 3, actively removing moisture by directing airflow through guide vanes 5. During transformer operation, buffer rod 17 and buffer plate 16 continuously absorb and disperse external impact forces, protecting the transformer's internal components from damage.

[0053] In one possible embodiment, a hydraulic cylinder 22 is provided at the top of the inner wall of the working box 18, a telescopic rod 23 is provided at the output end of the hydraulic cylinder 22, a limit plate 24 is provided at the bottom of the telescopic rod 23, an explosion-proof protective plate 25 is provided inside the limit plate 24, the limit plate 24 is provided above the oil-immersed transformer body 35, a dehumidification airflow pump 32 is provided at the bottom of the working box 18, one end of the delivery pipe 33 is provided at the output end of the dehumidification airflow pump 32, and the other end of the delivery pipe 33 is provided with a spray head 34, and the spray head 34 is provided above the oil-immersed transformer body 35.

[0054] In a specific application of this embodiment of the present invention, a hydraulic cylinder 22 is mounted on the top of the inner wall of the working box 18. The output end of the hydraulic cylinder 22 is connected to a telescopic rod 23. A limit plate 24 is fixed to the bottom of the telescopic rod 23 to control the spatial position above the oil-immersed transformer body 35. An explosion-proof shield 25 is embedded within the limit plate 24. In the event of a fault or abnormality within the transformer, the explosion-proof shield 25 effectively prevents explosion fragments or high-temperature gases from causing damage to the surrounding environment and personnel. The limit plate 24 also stabilizes the transformer body, preventing it from shaking during operation.

[0055] A dehumidifying airflow pump 32 is installed at the bottom of the working box 18, which is connected to a spray head 34 through a delivery pipe 33. The spray head 34 is located above the oil-immersed transformer body 35 and is used to evenly spray the dehumidifying airflow on the surface of the transformer body and the surrounding space. It can quickly reduce the humidity level inside the transformer and prevent insulation performance degradation or short-circuit failures caused by moisture. When the transformer is running, the hydraulic cylinder 22 drives the telescopic rod 23 to drive the limit plate 24 and the explosion-proof protective plate 25 to descend to the preset position to stabilize the transformer body. At the same time, the dehumidifying airflow pump 32 is started and the dry airflow is delivered to the spray head 34 through the delivery pipe 33. The spray head 34 sprays the airflow evenly on the transformer body and the surrounding space, forming a protective layer that effectively prevents external moisture from invading. As the transformer continues to operate, the dehumidifying airflow pumping system circulates continuously to ensure that the inside of the transformer always remains dry.

[0056] The hydraulic cylinder 22 is activated, driving the telescopic rod 23 to lower the limit plate 24 and the explosion-proof shield 25 to a position above the oil-immersed transformer body 35. Then, the dehumidification airflow pump 32 is activated to deliver the dry airflow to the spray head 34 through the delivery pipe 33. The spray head 34 evenly sprays the airflow on the transformer body and the surrounding space, forming a protective layer and reducing the humidity level.

[0057] During stable transformer operation, the dehumidifying airflow pumping system operates continuously, spraying dry air onto the transformer and surrounding area, ensuring the transformer interior remains dry. Simultaneously, the hydraulic cylinder 22 and telescopic rod 23 maintain the retaining plate 24 and explosion-proof shield 25 in their preset positions, providing stable support and protection for the transformer. When the transformer requires maintenance, the dehumidifying airflow pump 32 is first shut down, halting the airflow. The hydraulic cylinder 22 is then activated, driving the telescopic rod 23 to raise the retaining plate 24 and explosion-proof shield 25 away from the transformer, facilitating subsequent maintenance work.

[0058] In one possible embodiment, a control panel 19 is provided on the outside of the working box 18, and the control panel 19 is electrically controlled and connected to the bidirectional motor 10, the hydraulic cylinder 22, the limit plate 24, the electric telescopic device 27, the electric propeller 30 and the dehumidification airflow pump 32 through conductive lines.

[0059] In the specific application of the embodiment of the present invention, the bidirectional motor 10, hydraulic cylinder 22, limit plate 24, electric telescopic device 27, electric propeller 30 and dehumidification airflow pump 32 used in this device are all mature existing technologies. The working principles of the bidirectional motor 10, hydraulic cylinder 22, limit plate 24, electric telescopic device 27, electric propeller 30 and dehumidification airflow pump 32 are also well known to people in this technical field and will not be described in detail here.
