Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transformers, and in particular to a distribution transformer based on power grid environment self-adaptation and intelligent monitoring technology. Background Art
[0002] Transformers, the core equipment for voltage conversion in power systems, are widely used in various transmission lines. Oil-immersed transformers are particularly popular due to their adaptability to outdoor operation. These transformers typically rely on oil for insulation and heat dissipation, enhanced by a large number of heat sinks on their surfaces. However, the heat dissipation structure of existing oil-immersed transformers has significant limitations: when the wind direction is perpendicular or near perpendicular to the heat sinks, the middle heat sinks easily form dead zones for air flow, significantly reducing heat dissipation efficiency.
[0003] After searching, a Chinese patent with application number 202411338662.X discloses an adaptive distribution transformer for active power distribution networks, wherein a rotating assembly is provided on one side of the air guide plate, and the rotating assembly includes a rotating seat rotatably arranged on the heat sink, a rotating rod is fixedly connected to the top of the rotating seat, and the rotating rod is connected to a pulley drive assembly. The pulley drive assembly drives the rotating rod to rotate, which can drive the air guide plate to rotate to the side of the heat sink, so that the air guide plate and the corresponding heat sink form a container with only a top opening for receiving rainwater discharged by the rainwater conveying assembly, so that the rainwater can stay on the surface of the heat sink for a period of time, achieving a better heat dissipation effect. However, the inventor found that in the actual water cooling process of this technology, the cooling water needs to be gradually stored from the bottom to the top to achieve uniform heat dissipation.

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary persons in this field without making creative work are within the scope of protection of the present invention. The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described here. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to be able to fully convey the scope of the present invention to those skilled in the art.
[0024] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0025] Example 1: See Figures 1-11As shown, the present invention proposes a distribution transformer based on grid environment adaptation and intelligent monitoring technology, including a transformer body 1, a temperature sensor embedded in the transformer body 1 to monitor the internal temperature of the transformer body 1 in real time, and a controller (not shown) for controlling the operation of various electrical appliances. The temperature sensor uses high-precision and high-sensitivity components to capture the temperature changes inside the transformer body 1 in real time and accurately. These real-time temperature data will be continuously transmitted to the controller to provide an accurate basis for subsequent heat dissipation regulation. The outer wall of the shell of the transformer body 1 is fixed with a number of heat sinks 2, each of which is fixed with a plurality of heat sinks 2. The outer side of the heat sink 2 is provided with a wind guide plate 3, which is composed of two side and middle deflection plates. The inclined plate facilitates the effective conduction of wind in the environment and guides more airflow to the vicinity of the heat sink 2. The middle deflection plate adopts an arc setting, which can reduce the energy loss of wind in the conduction process, allowing the airflow to flow more smoothly through the heat sink 2, thereby taking away more heat. It also includes a deflection component 4, a water cooling unit, a water supply component 5 and an adaptive water guide mechanism 8. The deflection component 4 is connected to all the wind guide plates 3 on the same side, and is used to drive the wind guide plates 3 on the same side to synchronously achieve angular deflection, so as to achieve the purpose of guiding more directions. Wind, specifically, can be equipped with wind direction and wind force sensors, these sensors will monitor the external wind environment parameters in real time, and transmit the data to the controller. Based on these data, the controller sends a control instruction to the deflection component 4, drives the wind guide plate 3 to adjust the angle, so as to cope with and guide the wind in more directions. The water cooling unit is composed of a number of water cooling frames 6. The outer surface of each heat sink 2 is fitted with a water cooling frame 6. The side of the water cooling frame 6 that fits the heat sink 2 can be provided with a sealing strip to achieve sealing. The water supply component 5 is provided on the transformer body 1. When the temperature sensor detection value exceeds the preset threshold, the water supply component 5 is used to cool the transformer. Cooling water is supplied to each water-cooled frame 6, and a large amount of heat on the heat sink 2 is taken away by the flow of cooling water, thereby achieving rapid cooling. Several groups of adaptive water guide mechanisms 8 are evenly distributed in each water-cooled frame 6, and each group of adaptive water guide mechanisms 8 includes a partition 81 and a gravity-type conducting member. A water leakage hole 82 is opened on the partition 81. The multiple partitions 81 divide the water-cooled frame 6 into water storage and cooling chambers connected in series in the upper and lower parts. The water storage and cooling chambers generate pressure on the gravity-type conducting member through the water volume in the chamber, so that the water storage and cooling chambers from top to bottom are sequentially connected after storing a preset amount of cooling water, so that water can be stored in sequence from the upper end for cooling during water cooling.
[0026] Among them, see Figure 1-Figure 5As shown, the water supply assembly 5 includes a water tank 51, a water outlet pipe 53 and a water supply pipe 55. The water tank 51 is fixed to the top of the transformer body 1. The top of the water tank 51 is connected to a water supply bucket 52. When it rains, rainwater can be received through the water supply bucket 52 to automatically replenish water into the water tank 51. In addition, when it does not rain for a long time, the staff can replenish water into the water tank 51 through the water supply bucket 52 during regular inspections. A filter is installed in the water supply bucket 52. The filter can prevent fallen branches and leaves and other garbage from entering the water tank 51 to avoid clogging the water pipe. An overflow pipe is connected to the upper end of the side wall of the water tank 51. After the water in the water tank 51 is full, excess rainwater can be discharged from the overflow pipe to reduce the occurrence of turbulence. The water outlet pipe 53 is connected to the bottom end 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 water supply pipe 55 is connected to the bottom end of the water outlet pipe 53, and a plurality of vertical water supply branches 56 are connected to the water supply pipe 55. Each water supply branch 56 corresponds to a water cooling frame 6. When the temperature sensor senses that the temperature exceeds the set threshold, traditional air cooling cannot meet the needs. The temperature sensor immediately feeds back the information 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 water supply pipe 55, and then is sent to the corresponding water cooling frame 6 through the water supply branch 56 for water cooling.
[0027] The corners of the outer wall of the water-cooling frame 6 may be arc-shaped, which is beneficial for guiding the wind and reducing wind obstruction.
[0028] See Figures 8-11As shown, the gravity-type conducting member includes a movable plate 83, a second connecting rod 84 and a piston 86. The movable plate 83 is arranged above the corresponding partition 81. The second connecting rod 84 is connected to the lower end surface of the movable plate 83. A spring 85 is connected between the partition 81 and the movable plate 83. There are at least two springs 85. When two springs are provided, the two springs 85 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 spring 85 is in the natural state, the piston 86 is fixed to the bottom end of the second connecting rod 84. In this state, the piston 86 is in a state of blocking the water leakage hole 82. When the amount of water in the water storage and cooling chamber increases, the piston 86 and the movable plate 83 will be pressed down. When the downward pressure of the water is greater than the friction between the piston 86 and the water leakage hole 82 and the elastic deformation force of the spring 85, the piston 86 will move down and away from the water leakage hole 82 to allow the cooling water to enter the next water storage and cooling chamber. This cycle can realize water storage and conduction cooling from top to bottom in the dynamic flow of cooling water, compared with water storage and cooling from the bottom. When the amount of water in the water storage and cooling chamber gradually increases, the gravity generated by the water body will continue to act on the piston 86 and the movable plate 83, forming a downward pressure. As the amount of water continues to accumulate, this downward pressure gradually increases. In the initial stage with less water, 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 leakage hole 82, ensuring that the current water storage and cooling chamber is in a closed water storage state, which can accommodate a certain amount of cooling water and perform upper cooling. When the amount of water 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 fit with the leakage hole 82. The leakage hole 82 is opened, and the cooling water in the current water storage and cooling chamber will flow into the next water storage and cooling chamber through the leakage hole 82. The cooling water entering the next water storage and cooling chamber will repeat the above process.
[0029] This design allows the cooling water to be partially stored and cooled in each water storage and cooling chamber from top to bottom during the dynamic flow process. Compared with the traditional method of slowly storing water and cooling from the bottom to the top, it has the following advantages: The cavities that are connected in sequence from top to bottom can form segmented cooling. Each water storage cooling cavity can fully play its role in sequence, and the cooling water continuously exchanges heat with the cavity during the flow, which not only improves the overall utilization rate of the cooling system, but also makes the cooling effect more uniform and stable, effectively improving the efficiency and reliability of the entire cooling process; in contrast, when water is stored from the lower end upward, all cavities are finally filled with water before the overall heat is dissipated. Lacking this step-by-step heat exchange mechanism, the heat exchange intensity is weak.
[0030] 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 cooling water flow direction from top to bottom complements the upward flow of thermal convection: the low-temperature water at the top is replenished downward, and the hot water at the bottom moves upward due to thermal convection, forming a cycle and accelerating the transfer of heat from the heat sink to the water body.
[0031] In addition, when water is stored from top to bottom, as the water flows downward, bubbles (air dissolved in the water) can be gradually discharged upward with the water flow, reducing the probability of bubbles being retained on the outer wall of the heat sink 2 (bubbles will hinder the contact between water and the heat sink 2, reducing the heat dissipation efficiency); if water is stored from the bottom to the top, the bubbles may be pressed on 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.
[0032] In addition, it should be noted that the selection of the spring 85 and the piston 86 needs to meet the requirement that when 1 / 3-1 / 2 of the water is stored in the water storage and cooling chamber, the piston 86 can move downward to release the blockage of the water leakage hole 82. Compared with gradually storing water from the bottom end (the water storage time from the bottom end to the top end is long, which makes the heat dissipation temperature difference between the upper and lower ends too large, and time will cause damage to the heat sink 2, and the cooling effect is better), the cooling effect is better (water is stored in sections from the top end to the bottom, and the water storage volume does not need to be full, so that the time for cooling water from the top end to the bottom end is shorter, and the cooling water continuously flows down from the top end, which can play the role of impacting water, increase the turbulence of the water flow in the water storage and cooling chamber, and further improve the cooling effect of the heat sink 2).
[0033] See Figure 2-Figure 4 as well as Figure 6-Figure 7 As shown, the deflection assembly 4 includes: The telescopic member 41 may be an electric telescopic rod, and the output end of the telescopic member 41 is connected to a rack 42; A plurality of followers 43 are provided, and a follower 43 is rotatably provided on the upper end of each heat sink 2 . The follower 43 includes a gear 433 , and the gear 433 is meshedly connected to the rack 42 .
[0034] Among them, participation Figure 7 As 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, and the gear 433 is fixed to the top of the cylinder 431. A fixing rod is connected between the outer wall of the cylinder 431 and the wind guide plate 3. When the telescopic member 41 is started, the telescopic member 41 can be used to move the rack 42. During the movement of the rack 42, it can drive multiple gears 433 engaged with it to transmit, thereby driving the cylinder 431 to rotate, thereby causing the wind guide plate 3 to deflect to adjust the wind guide direction to meet the air cooling needs under various wind directions.
[0035] Among them, a rotatable mounting rod 432 can also be fixedly connected to the lower end of the heat sink 2, and the bottom end of the mounting rod 432 is rotatably connected to the cylinder 431. A fixed rod is also connected between the outer wall of the cylinder 431 and the air guide plate 3 to limit the air guide plate 3 from the bottom end to ensure the stability of the air guide plate 3 when it is deflected.
[0036] In addition, the deflection assembly 4 also includes a plurality of 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 sliding the rack 42 is provided on the horizontal section of the L-shaped guide plate 44, and a limiting guide groove is provided on the upper end surface of the guide groove. A limiting guide bar is provided on the upper end surface 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 skewing.
[0037] As described 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. To cope with the problem of different wind directions, the deflection component 4 and the wind guide plate 3 cooperate to achieve a certain angle of deflection of the wind guide plate 3, thereby directing more air to the heat sink 2. When the temperature sensor senses that the temperature exceeds the set threshold, it is difficult to meet the heat dissipation needs through natural wind and the heat sink 2. At this time, the controller controls the water supply component 5 to add cooling water to the water cooling 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 in the heat sink 2 to increase the heat dissipation effect. When the temperature sensor senses that the temperature exceeds the set threshold, the controller can cut off the water supply of the water supply component 5 to avoid waste of water resources, thereby realizing intelligent monitoring of temperature and switching of adaptive cooling methods.
[0038] Example 2: See Figure 6 as well as Figures 8-11 As shown, this embodiment is extended on the basis of the first embodiment. The distribution transformer based on the grid environment adaptation and intelligent monitoring technology also includes a follower stamping component 7. One end of the follower stamping component 7 is connected to the wind guide plate 3, and the other end of the follower stamping component 7 extends into the water storage cooling cavity. When the wind guide plate 3 is deflected, the follower stamping component 7 squeezes the movable plate 83 and impacts the cooling water, and the impact direction is facing the outer wall of the heat sink 2.
[0039] Among them, the follower punching assembly 7 includes: A connecting strip 71, one end of which is fixed to the air guide plate 3, and a guide groove 74 is formed on the other end of the connecting strip 71, and the guide groove 74 is formed along the length direction of the connecting strip 71; The pressing block 72 is arranged in the water storage cooling chamber, and is connected to the first connecting rod 73 that passes through the water cooling frame 6. A sealing ring is provided at the position where the first connecting rod 73 passes through the water cooling frame 6 to ensure that the first connecting rod 73 can be telescopically moved while avoiding water leakage. The outer end of the first connecting rod 73 passes through the guide groove 74, and baffles 75 are fixed on the outside of the first connecting rod 73 and on both sides of the connecting bar 71. The baffles 75 limit the first connecting rod 73 from separating from the connecting bar 71. The pressing block 72 is provided with an extrusion inclined surface on the side facing the movable plate 83, and the upper end surface of the movable plate 83 is provided with a pressure inclined surface.
[0040] Through the above, when the water-cooling frame 6 is used to store water for water cooling, the telescopic member 41 can be synchronously controlled to perform periodic expansion and contraction, thereby directly driving the air guide plate 3 to deflect back and forth periodically. The air guide plate 3 can form a regular airflow disturbance in the heat dissipation space. Secondly, in one cycle, the connecting strip 71 will squeeze the first connecting rod 73 provided with the baffle 75, so as to use the pressing block 72 provided with the extrusion slope to squeeze the movable plate 83 provided with the pressure slope, so that the piston 86 moves down and up, playing the role of disturbing the flow. At the same time, the pressing block 72 will also impact the cooling water in the water storage cooling chamber during the movement. On the one hand, it can effectively Increasing the turbulence of the cooling water allows the cooling water that is away from the outer wall of the heat sink 2 to flow toward 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 will continuously impact the outer wall of the heat sink 2 during the flow process. 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, and 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.
