Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a distribution transformer based on power grid environment adaptive and intelligent monitoring technology. Background Technology

[0002] Transformers, as core equipment for voltage transformation in power systems, are widely used in various transmission lines. Among them, oil-immersed transformers are commonly used due to their suitability for outdoor operation. These transformers typically rely on oil for insulation and heat dissipation, and enhance the heat dissipation effect through numerous heat sinks on their surface. However, the existing heat dissipation structure of oil-immersed transformers has significant limitations: when the wind direction is perpendicular or nearly perpendicular to the heat sinks, the heat sinks in the middle position easily form dead airflow angles, resulting in a significant decrease in heat dissipation efficiency.

[0003] A search revealed a Chinese patent application (application number 202411338662.X) disclosing an adaptive distribution transformer for active distribution networks. This transformer features a rotating assembly on one side of a wind deflector. This assembly includes a rotating seat rotatably mounted on a heat sink, with a rotating rod fixedly connected to the top of the seat. The rotating rod is connected to a pulley drive assembly. Driving the rotating rod via the pulley drive assembly rotates the wind deflector to the side of the heat sink, creating a container with only a top opening to receive rainwater discharged from a rainwater conveying assembly. This allows the rainwater to remain on the heat sink surface for a period, resulting in better heat dissipation. However, the inventors found that in actual water cooling processes, the cooling water needs to be gradually stored from the bottom to the top to achieve uniform heat dissipation, leading to cooling delays and excessive temperature differences between the top and bottom. Long-term use may damage the heat sink, making it difficult to meet the demands for efficient and rapid heat dissipation. Therefore, this paper proposes a distribution transformer based on adaptive power grid environment and intelligent monitoring technology. Summary of the Invention

Each mechanism includes a partition and a gravity-type conductive component. The partition has a water leakage hole. Multiple partitions divide the water-cooling frame into water-storing cooling chambers connected in series. The water-storing cooling chambers achieve sequential connection from top to bottom after storing a preset amount of cooling water by the pressure generated by the water volume in the chamber on the gravity-type conductive component.

[0010] Preferably, the gravity-type conductive element includes:

[0011] An movable panel is positioned above the corresponding partition.

[0012] The second connecting rod is connected to the lower end face of the movable plate;

[0013] A spring is connected between the partition and the movable plate;

[0014] The piston is fixed to the bottom end of the second connecting rod. In the natural state of the spring, the piston is in the state of sealing the leakage hole.

[0015] Preferably, it also includes a follow-up stamping component, one end of which is connected to the air guide plate and the other end extends into the water storage cooling chamber. When the air guide plate deflects, the follow-up stamping component squeezes the movable plate and impacts the cooling water.

[0016] Preferably, the follow-up stamping assembly includes:

[0017] The connecting strip has one end fixed to the air guide plate and the other end has a guide groove.

[0018] A pressure block is provided inside the water storage cooling chamber, and a first connecting rod that penetrates the water cooling frame is connected to the pressure block. The outer end of the first connecting rod penetrates the guide groove, and baffles are fixed on both sides of the first connecting rod outside the connecting rod and on both sides of the connecting strip.

[0019] Preferably, the side of the pressure block facing the movable plate is provided with a pressing slope, and the upper end surface of the movable plate is provided with a pressure-receiving slope.

[0020] Preferably, the deflection component includes:

[0021] A telescopic component, the output end of which is connected to a rack;

[0022] Multiple follower components are provided, and each heat sink has a follower component rotatably mounted on its upper end. The follower component includes a gear that meshes with a rack.

[0023] Preferably, the follower further includes a cylinder and a mounting rod, the mounting rod is fixed on the heat sink, the cylinder is rotatably mounted on the top of the mounting rod, the gear is fixed on the top of the cylinder, and a fixing rod connects the outer wall of the cylinder and the air guide plate.

[0024] Preferably, the deflection assembly further includes multiple L-shaped guide plates, each L-shaped guide plate having a guide groove for sliding the rack, a limiting guide groove on the upper end face of the guide groove, and a limiting guide bar on the upper end face of the rack.

[0025] Preferably, the water supply component includes:

[0026] The water tank is fixed to the top of the transformer body;

[0027] A water outlet pipe is connected to the bottom of the water tank, and an electrically controlled valve is installed on the water outlet pipe;

[0029] Preferably, a water supply hopper is connected to the top of the water tank, a filter screen is installed inside the water supply hopper, and an overflow pipe is connected to the upper end of the side wall of the water tank.

[0030] The technical solution provided by this invention may include the following beneficial effects:

[0031] 1. In the water-cooling unit of the present invention, the adaptive water guiding mechanism divides the water-cooling frame into upper and lower series water storage and cooling chambers through a partition. The cooling water is guided from top to bottom by gravity-type conductive components. Compared with the traditional bottom water storage mode, this design can make the cooling water partially and quickly remain in each chamber and form a stepped heat exchange, reduce the temperature difference between the upper and lower ends, avoid damage to the heat sink, and enhance the water flow turbulence effect to improve the heat exchange efficiency.

[0032] 2. In this invention, when the follow-up stamping component deflects with the air guide plate, it can squeeze the movable plate and impact the cooling water. On the one hand, it increases the water flow turbulence to enhance heat exchange, and on the other hand, it reduces the adhesion of scale on the outer wall of the heat sink and extends the service life of the equipment. In addition, the angle adjustment of the air guide plate and the linkage with the water cooling system realize the intelligent coordination of air cooling and water cooling, further improving the heat dissipation performance.

[0033] 3. In this invention, the deflection component drives the air guide plate to adjust its angle synchronously, and in conjunction with wind direction and wind force sensors, it achieves dynamic adaptation to different wind directions. This can guide more airflow to the heat sink area, avoid the heat dissipation dead angle caused by wind direction issues in traditional structures, and significantly improve the air cooling effect.

[0034] 4. In this invention, the L-shaped guide plate in the deflection assembly guides and limits the rack, and the gear meshing transmission of the follower ensures that the angle adjustment of the air guide plate is accurate and stable; the spring and piston of the adaptive water guiding mechanism cooperate to ensure that the cooling water is guided sequentially according to the preset amount, thereby improving the overall reliability of the equipment operation.

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention. Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0056] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] Example 1:

[0058] See Figures 1-11As shown, this invention proposes a distribution transformer based on power grid environment adaptive and intelligent monitoring technology, including a transformer body 1. A temperature sensor is embedded inside the transformer body 1 to monitor the internal temperature of the transformer body 1 in real time. It also includes a controller (not shown) for controlling the operation of various electrical appliances. The temperature sensor uses high-precision, high-sensitivity components, enabling it to accurately capture temperature changes inside the transformer body 1 in real time. This real-time temperature data is continuously transmitted to the controller, providing an accurate basis for subsequent heat dissipation control. Several heat sinks 2 are fixed to the outer wall of the transformer body 1. An air guide plate 3 is installed on the outer side of the heat sink 2. The air guide plate 3 consists of deflector plates on both sides and in the middle. The inclined plates facilitate the effective conduction of airflow in the environment, guiding more airflow to the vicinity of the heat sink 2. The deflector plate in the middle is arc-shaped, which can reduce energy loss during air conduction and allow airflow to flow more smoothly over the heat sink 2, thereby carrying away more heat. It also includes a deflection component 4, a water cooling unit, a water supply component 5, and an adaptive water guiding mechanism 8. The deflection component 4 is connected to all air guide plates 3 on the same side and is used to drive the air guide plates 3 on the same side to simultaneously achieve angle deflection, so as to cope with the guidance of airflow in more directions. The wind system can be equipped with wind direction and wind force sensors. These sensors monitor external wind environment parameters in real time and transmit the data to the controller. Based on this data, the controller sends control commands to the deflection component 4 to drive the wind guide plate 3 to adjust its angle, thereby coping with and guiding wind from more directions. The water-cooling unit consists of several water-cooling frames 6. Each heat sink 2 has a water-cooling frame 6 attached to its outer surface. A sealing strip can be installed on the side of the water-cooling frame 6 that is attached to the heat sink 2 to achieve a seal. The water supply component 5 is installed on the transformer body 1. When the temperature sensor detects a value exceeding a preset threshold, the water supply component 5... Cooling water is supplied to each water-cooled frame 6. The flow of cooling water carries away a large amount of heat from the heat sink 2, achieving rapid cooling. Several sets of adaptive water guiding mechanisms 8 are evenly distributed in each water-cooled frame 6. Each set of adaptive water guiding mechanisms 8 includes a partition 81 and a gravity-type conductive component. A water leakage hole 82 is opened on the partition 81. Multiple partitions 81 divide the water-cooled frame 6 into upper and lower connected water storage cooling chambers. The water storage cooling chambers are connected sequentially from top to bottom after storing a preset amount of cooling water by the pressure generated by the water volume in the chamber on the gravity-type conductive component. This allows water to be stored sequentially from the top for cooling during water cooling.

[0059] Among them, see Figures 1-5As shown, the water supply assembly 5 includes a water tank 51, an outlet pipe 53, and a main water supply pipe 55. The water tank 51 is fixed to the top of the transformer body 1. A water replenishment hopper 52 is connected to the top of the water tank 51. When it rains, rainwater can be collected through the water replenishment hopper 52 to automatically replenish water into the water tank 51. In addition, when there is no rain for a long time, water can be replenished into the water tank 51 through the water replenishment hopper 52 during regular inspections. A filter screen is installed inside the water replenishment hopper 52 to prevent fallen branches and leaves and other debris from entering the water tank 51, thus avoiding blockage of the water pipe. An overflow pipe is connected to the upper side wall of the water tank 51. When the water tank 51 is full, rainwater can be discharged from the overflow pipe, reducing turbulence. The water outlet pipe 53 is connected to the bottom of the water tank 51, and an electric control valve 54 is installed on the water outlet pipe 53. The electric control valve 54 is electrically connected to the controller. The main water supply pipe 55 is connected to the bottom of the water outlet pipe 53, and multiple vertical water supply branch pipes 56 are connected to the main water supply pipe 55. Each water supply branch pipe 56 corresponds to a water-cooled frame 6. When the temperature sensor detects that the temperature exceeds the set threshold, traditional air cooling is insufficient. The temperature sensor immediately feeds the information back to the controller, and the controller controls the electric control valve 54 to open, so that the water in the water tank 51 can flow through the water outlet pipe 53 to the main water supply pipe 55, and then be sent into the corresponding water-cooled frame 6 through the water supply branch pipes 56 for water cooling.

[0060] The outer corner of the water-cooled frame 6 can be rounded to facilitate airflow and reduce wind obstruction.

[0061] See Figures 8-11As shown, the gravity-type conductive component includes a movable plate 83, a second connecting rod 84, and a piston 86. The movable plate 83 is positioned above the corresponding partition 81. The second connecting rod 84 is connected to the lower end face of the movable plate 83. A spring 85 is connected between the partition 81 and the movable plate 83. At least two springs 85 are provided. When two springs 85 are provided, they are located on both sides of the second connecting rod 84 to evenly support the movable plate 83. The piston 86 is fixed to the bottom end of the second connecting rod 84. When the springs 85 are in their natural state... In this state, piston 86 is in the state of blocking the water leakage hole 82. As the water volume in the water storage cooling chamber increases, it will press down piston 86 and movable plate 83. When the downward pressure of the water is greater than the friction between piston 86 and water leakage hole 82 and the elastic deformation force of spring 85, piston 86 will move down and disengage from water leakage hole 82, so that cooling water can enter the next water storage cooling chamber. This cycle continues, and water storage and conduction cooling can be achieved from top to bottom during the dynamic flow of cooling water, compared to water storage and cooling from the bottom. As the water volume in the water storage cooling chamber gradually increases, the gravity generated by the water will continuously act on the piston 86 and the movable plate 83, forming downward pressure. As the water volume continues to accumulate, this downward pressure gradually increases. In the initial stage when the water volume is small, the downward pressure is less than the sum of the friction force and the elastic force of the spring 85. The piston 86 will seal the drain hole 82 to ensure that the current water storage cooling chamber is in a closed water storage state, which can accommodate a certain amount of cooling water and perform upper-layer cooling. However, as the water volume continues to increase, the downward pressure continues to increase. After exceeding the sum of the friction force and the elastic force of the spring 85, the piston 86 will overcome the resistance and move downward, breaking away from the sealed state with the drain hole 82. The drain hole 82 is opened, and the cooling water in the current water storage cooling chamber will flow into the next water storage cooling chamber through the drain hole 82. The cooling water entering the next water storage cooling chamber will repeat the above process.

[0062] This design allows cooling water to partially store and conduct cooling water sequentially from top to bottom within each water storage and cooling chamber during dynamic flow. Compared to the traditional method of storing and cooling water slowly from the bottom up, this design offers the following advantages:

[0063] The sequentially connected cavities from top to bottom form a segmented cooling system, with each water-storage cooling cavity functioning fully in sequence. The cooling water continuously exchanges heat with the cavities as it flows, which not only improves the overall utilization rate of the cooling system but also makes the cooling effect more uniform and stable, effectively enhancing the efficiency and reliability of the entire cooling process. In contrast, when water is stored at the bottom and then upwards, all cavities are eventually filled with water before the overall heat dissipation occurs, lacking this stepped heat exchange mechanism and resulting in weaker heat exchange intensity.

[0064] Secondly, after the heat sink 2 absorbs heat, the surrounding water will decrease in density due to the increase in temperature and naturally flow upward (thermal convection phenomenon). The downward flow of cooling water complements the upward flow of thermal convection: the low-temperature water in the upper part replenishes downward, while the hot water in the lower part moves upward due to thermal convection, forming a circulation and accelerating the transfer of heat from the heat sink to the water body.

[0065] In addition, when water is stored from top to bottom, as the water flows downward, air bubbles (air dissolved in the water) can gradually be discharged upward with the water flow, reducing the probability of air bubbles remaining on the outer wall of the heat sink 2 (air bubbles will hinder the contact between water and heat sink 2, reducing heat dissipation efficiency); if water is stored from bottom to top, air bubbles may be pressed onto the heat sink 2 by the upward flowing water, making it difficult to discharge, resulting in poor heat dissipation in local areas and affecting the overall heat dissipation uniformity.

[0066] Additionally, it should be noted that the selection of spring 85 and piston 86 should be such that when the water storage chamber is filled with 1 / 3 to 1 / 2 of the water, piston 86 can move down to release the seal on the water leakage hole 82. Compared to gradually storing water from the bottom (which takes a long time from bottom to top, resulting in a large temperature difference between the top and bottom, which will damage the heat sink 2), the cooling effect is better (storing water from top to bottom in sections, and the water volume does not need to be full, which shortens the time for the cooling water to flow from top to bottom, and the cooling water flows continuously from top to bottom, which can play the role of impact water, increase the turbulence of the water flow in the water storage chamber, and further improve the cooling effect of the heat sink 2).

[0067] See Figures 2-4 as well as Figures 6-7 As shown, the deflection component 4 includes:

[0068] Telescopic component 41, which can be an electric telescopic rod, has a rack 42 connected to its output end;

[0069] Multiple follower elements 43 are provided, and each heat sink 2 is rotatably provided with a follower element 43 at its upper end. The follower element 43 includes a gear 433, which is meshed with a rack 42.

[0070] Among them, participants Figure 7As shown, the follower 43 also includes a cylinder 431 and a mounting rod 432. The mounting rod 432 is fixed on the heat sink 2, and the cylinder 431 is rotatably mounted on the top of the mounting rod 432. Specifically, the top of the mounting rod 432 can be connected to the cylinder 431 through a bearing. The gear 433 is fixed on the top of the cylinder 431. A fixed rod is connected between the outer wall of the cylinder 431 and the air guide plate 3. When the telescopic component 41 is activated, the rack 42 can be moved by the telescopic component 41. During the movement of the rack 42, multiple gears 433 meshing with it can be driven to rotate, thereby driving the cylinder 431 to rotate, which in turn causes the air guide plate 3 to deflect to adjust the air guiding direction in order to meet the air cooling needs under various wind directions.

[0071] Among them, a rotating mounting rod 432 can also be fixedly connected to the lower end of the heat sink 2. The bottom end of the mounting rod 432 is rotatably connected to the cylinder 431. A fixing rod is also connected between the outer wall of the cylinder 431 and the air guide plate 3 to restrict the air guide plate 3 from the bottom end and ensure the stability of the air guide plate 3 when it deflects.

[0072] In addition, the deflection assembly 4 also includes multiple L-shaped guide plates 44, which can be made of high-strength alloy material. The upper end of the L-shaped guide plate 44 can be fixed on the water tank 51 or the outer wall of the transformer body 1. A guide groove for the rack 42 to slide is opened on the horizontal section of the L-shaped guide plate 44. A limiting guide groove is provided on the upper end face of the guide groove. A limiting guide bar is provided on the upper end face of the rack 42. When the rack 42 moves, the rack 42 moves along the guide groove, and the limiting guide bar moves along the limiting guide bar, which can effectively guide the movement of the rack 42 and prevent the rack 42 from tilting.

[0073] Based on the above, in actual use, when the temperature of the transformer body 1 does not exceed the set threshold, the heat sink 2 can be used for heat dissipation. In order to deal with the problem of different wind directions, the deflection component 4 and the air guide plate 3 can be used together to deflect the air guide plate 3 at a certain angle, so as to deliver more air to the heat sink 2.

[0074] When the temperature sensor detects that the temperature exceeds the set threshold, natural wind combined with heat sink 2 is insufficient to meet the heat dissipation requirements. At this time, the controller controls the water supply component 5 to add cooling water to the water-cooled frame 6. The cooling water is stored and cooled in a certain amount from top to bottom, which can effectively increase the residence time of the cooling water on the heat sink 2 and increase the heat dissipation effect. When the temperature sensor detects that the temperature does not exceed the set threshold, the controller can cut off the water supply component 5 to avoid wasting water resources. Thus, it is possible to realize the switching of adaptive cooling mode based on intelligent temperature monitoring.

[0075] Example 2:

[0076] See Figure 6 as well as Figures 8-11As shown, this embodiment is an extension of the first embodiment. The distribution transformer based on the power grid environment adaptive and intelligent monitoring technology also includes a follow-up stamping component 7. One end of the follow-up stamping component 7 is connected to the air guide plate 3, and the other end of the follow-up stamping component 7 extends into the water storage cooling chamber. When the air guide plate 3 deflects, the follow-up stamping component 7 squeezes the movable plate 83 and impacts the cooling water, and the impact direction is directly opposite to the outer wall of the heat sink 2.

[0077] The follow-up stamping assembly 7 includes:

[0078] A connecting strip 71 is provided, one end of which is fixed to the air guide plate 3, and a guide groove 74 is provided on the other end of the connecting strip 71. The guide groove 74 is provided along the length of the connecting strip 71.

[0079] The pressure block 72 is located inside the water storage cooling chamber, and a first connecting rod 73 that penetrates the water-cooling frame 6 is connected to the pressure block 72. A sealing ring is provided at the position where the first connecting rod 73 penetrates the water-cooling frame 6 to ensure that the first connecting rod 73 can be extended and retracted while preventing water leakage. The outer end of the first connecting rod 73 penetrates the guide groove 74. Baffles 75 are fixed on both sides of the first connecting rod 73 and on both sides of the connecting strip 71. The baffles 75 restrict the first connecting rod 73 from detaching from the connecting strip 71. The side of the pressure block 72 facing the movable plate 83 is provided with a pressing slope, and the upper end surface of the movable plate 83 is provided with a pressure-bearing slope.

[0080] As described above, when using the water-cooled frame 6 to store water for water cooling, the telescopic component 41 can be controlled to periodically extend and retract, thereby directly driving the air guide plate 3 to periodically deflect back and forth. The air guide plate 3 can form regular airflow disturbances in the heat dissipation space. Secondly, within one cycle, the connecting bar 71 will squeeze the first connecting rod 73 with the baffle 75, so that the pressure block 72 with the pressure slope will squeeze the movable plate 83 with the pressure slope, so that the piston 86 will move down and up, playing a role in turbulence. At the same time, the pressure block 72 will also impact the cooling water in the water storage cooling chamber during the movement, which can effectively Increasing the turbulence of the cooling water allows the cooling water away from the outer wall of the heat sink 2 to flow towards the heat sink 2 more quickly and in greater quantities, greatly improving the heat exchange efficiency between the cooling water and the heat sink 2 and significantly enhancing the cooling effect. On the other hand, the impacted cooling water continuously impacts the outer wall of the heat sink 2 during its flow. This continuous impact can effectively reduce the adhesion of scale on the outer wall of the heat sink 2, because the formation of scale will hinder heat transfer. In this way, the accumulation rate of scale can be slowed down, ensuring that the heat sink 2 maintains good heat dissipation performance for a long time, extending the service life of the entire cooling system and reducing maintenance costs.
