Description

Technical Field

[0001] The invention belongs to the technical field of transformers, in particular to an intelligent temperature-controlled dry-type transformer. Background Art

[0002] As the name suggests, a dry-type transformer is a transformer that does not need to be immersed in insulating oil to dissipate heat. Dry-type transformers usually use natural air cooling or forced air cooling. Dry-type transformers with heavier loads will use forced air cooling. Forced air cooling uses a fan to drive air flow, and the air takes away the heat of the dry-type transformer to keep it at a stable operating temperature.

[0003] A patent application with an existing authorization announcement number CN220774087U discloses a dry-type transformer. By arranging multiple elastic support rods between the dry-type transformer body and the transformer shell, the vibration generated during the operation of the dry-type transformer body is dispersed to the transformer shell, thereby reducing the amplitude of the vibration during the operation of the dry-type transformer body.

[0004] When the above technical solution is in use, the heat of the transformer is taken away by extracting air. However, the contact area between the metal shell of the transformer and the air is small, and the heat that can be taken away during the air flow is also small. When the transformer is running under high load, a large amount of heat will be generated. At this time, the air cannot take away the heat of the metal shell of the transformer in time, causing the transformer to be in a high temperature state, affecting the stability of the transformer.

[0005] To this end, the present invention provides an intelligent temperature-controlled dry-type transformer. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 3As shown, an intelligent temperature-controlled dry-type transformer described in an embodiment of the present invention includes a transformer box 1, a dry-type transformer main body 4 is installed inside the transformer box 1, temperature measuring probes 11 are arranged on both sides of the dry-type transformer main body 4, and the temperature measuring probes 11 are installed at the bottom end of the transformer box 1, and air outlet hoods 12 are fixed on both sides of the transformer box 1, and a heat dissipation fan 5 is installed inside the air outlet hood 12, and a plurality of heat conducting plates 8 are arranged on both sides of the dry-type transformer main body 4; three groups of heat conducting plates 8 are arranged, and the side of each group of heat conducting plates 8 away from the dry-type transformer main body 4 is fixedly connected by a support rod 81, and a support shell 82 is arranged below the support rod 81, and the bottom end of the support rod 81 is fixed with a slider 811, and the slider 811 is slidably connected to the inside of the support shell 82, and a guide rod 822 is fixed inside the support shell 82, and the guide rod 822 runs through the interior of the slider 811, and a spring 821 is sleeved on the outside of the guide rod 822. A movable groove 83 is provided at the top and bottom of the heat conducting sheet 8, and a plurality of heat sinks 831 are hinged at equal intervals inside the movable groove 83. A metal elastic sheet 832 is fixed to one end of the heat sink 831 rotating shaft close to the dry-type transformer body 4, and a cavity for the movement of the metal elastic sheet 832 is provided inside the heat conducting sheet 8. A pull plate 833 is fixed to the other end of the rotating shaft of the heat sink 831. A movable frame 84 is provided on both sides of the dry-type transformer body 4, and a plurality of steel ropes 841 are fixed between the two movable frames 84. The steel ropes 841 are fixedly connected to the top of the pull plate 833. A winding device 85 is installed at one end of the transformer box 1 close to the water pump 22, and a traction rope 842 is fixed to the side of the movable frame 84 away from the steel rope 841, and the other end of the traction rope 842 is wound around the outside of the winding wheel of the winding device 85.

[0038] During the use of the dry-type transformer, the current passing through the inside will generate a large amount of heat due to the resistance of the components inside the transformer. When the heat rises, the internal resistance of the transformer will increase, resulting in a lower efficiency of the transformer in processing current. At the same time, there are safety hazards. Therefore, it is necessary to control the temperature of the transformer during use. Before the dry-type transformer main body 4 is installed, it is necessary to push the heat conductive sheet 8 to both sides. At this time, the heat conductive sheet 8 drives the slider 811 to slide inside the support shell 82 through the support rod 81. At the same time, the slider 811 squeezes the spring 821. Then the dry-type transformer main body 4 is installed inside the transformer box 1. After installation, the elastic force of the spring 821 pushes the slider 811 to slide in the opposite direction. At this time, the support rod 81 drives the heat conductive sheet 8 to stick close to the dry-type transformer. The temperature probe 11 monitors the temperature inside the transformer box 1 in real time on the surface of the main body 4, and dissipates heat through temperature control. When the temperature is high, the heat dissipation fan 5 is started to exhaust air to the outside of the transformer box 1. At this time, the heat dissipation fan 5 draws the air inside the transformer box 1 and discharges it to the outside through the air outlet hood 12. The heat on the surface of the dry-type transformer main body 4 will be taken away during the air flow inside the transformer box 1. At this time, the dry-type transformer main body 4 will transfer the heat to the heat conductive sheet 8. The metal shell on the surface of the dry-type transformer main body 4 can be used for heat conduction. The metal shell of the dry-type transformer main body 4 transfers the heat to the surface of the heat conductive sheet 8. At this time, the airflow for heat dissipation inside the transformer box 1 will contact the surface of the heat conductive sheet 8. At this time, the heat conductive sheet 8 can increase the heat dissipation between the dry-type transformer main body 4 and The area of ​​airflow contact can enhance the heat dissipation effect. During use, the temperature of the dry-type transformer body 4 is in a high state, and the heat on the surface of the heat conductive sheet 8 will not be dissipated in time. At this time, it is necessary to increase the contact area between the heat conductive sheet 8 and the airflow, and start the winding device 85 to wind up the traction rope 842. At this time, the traction rope 842 pulls the moving frame 84 to move. During the movement, the moving frame 84 pulls the steel rope 841, and the steel rope 841 pulls the pull plate 833. At this time, the pull plate 833 drives the heat dissipation sheet 831 to flip. At this time, the heat dissipation sheet 831 will flip 45° from the inside of the movable groove 83. At this time, the heat dissipation sheet 831 can increase the contact area between the heat conductive sheet 8 and the airflow, which can further enhance the heat dissipation effect of the dry-type transformer body 4. At the same time, the metal elastic sheet 832 will be in the heat dissipation The heat sheet 831 automatically deforms when it flips. When the dry-type transformer body 4 is within the normal temperature range, the winding device 85 is started to unwind the traction rope 842. At this time, the elastic force of the metal elastic sheet 832 will drive the heat sink 831 to flip in the opposite direction. At this time, the heat sink 831 is retracted into the inside of the movable groove 83, and the pull plate 833 will also flip to the original position for the next use. The heat dissipation area of ​​the heat conductive sheet 8 can be automatically adjusted according to the temperature of the dry-type transformer body 4. The transformer box 1 and the dry-type transformer body 4 are in a separated state. The sunlight shines on the transformer box 1 to block the sunlight, and at the same time, the heat of the transformer box 1 will not be directly conducted to the inside of the dry-type transformer body 4, which can reduce the heat inside the dry-type transformer body 4 and keep the dry-type transformer body 4 in a stable state.

[0039] like Figures 1 to 3 As shown, dustproof plates 121 are provided on both sides of the transformer box 1 near the air outlet hood 12, the top of the dustproof plates 121 are hinged to the side wall of the transformer box 1, and the dustproof plates 121 form a flip structure at the outlet of the air outlet hood 12;

[0040] When air flows into the air outlet hood 12, the external air may contain impurities and other objects. The impurities enter the transformer box 1 and accumulate, and may come into contact with the dry-type transformer body 4 in hot weather and cause a fire. In order to prevent the impurities from accumulating inside the transformer box 1 and on the surface of the dry-type transformer body 4, it is necessary to filter out the impurities. Therefore, a dustproof plate 121 is provided at the air outlet position of the air outlet hood 12. Because two heat dissipation fans 5 are provided, when one heat dissipation fan 5 draws air to the outside of the transformer box 1, the dustproof plate 121 at the opposite position can filter out impurities from the air entering the air outlet hood 12. When the dustproof plate 121 is used for a long time, the inside will be blocked due to the accumulation of impurities. At this time, the speed of the heat dissipation fan 5 remains unchanged, but the power of the heat dissipation fan 5 will gradually increase. When the power When the abnormal value range is reached, it can be detected that the dustproof plate 121 is in a blocked state, so the running cooling fan 5 is turned off, and the cooling fan 5 at the same end as the blocked dustproof plate 121 is started. The cooling fan 5 is turned on with the highest power and the speed is also at the highest. At this time, the cooling fan 5 blows towards the blocked dustproof plate 121, and the dustproof plate 121 is blown and flipped. After flipping, the cooling fan 5 is turned off. At this time, the dustproof plate 121 returns to its original position due to gravity, and at the same time, the dustproof plate 121 collides with the outer wall of the transformer box body 1. The vibration generated by the collision can vibrate the impurities inside and on the surface of the dustproof plate 121. By reciprocating for multiple times, the inside of the dustproof plate 121 can be cleaned more cleanly. Two cooling fans 5 with different blowing directions are set at both ends. When the dustproof plate 121 at one end is blocked and heat dissipation is urgently needed, the other end can be enabled for heat dissipation.

[0041] like Figures 1 to 4 As shown, a water tank 2 is fixed on the top of the transformer box 1, and clean water is filled in the water tank 2. Heat pipes 21 are fixed on both sides of the bottom of the water tank 2, and the heat pipes 21 are fixedly connected to the inner wall of the transformer box 1. A heat sink 23 is installed inside one of the air outlet covers 12, and the other end of the heat pipe 21 is connected to both sides of the heat sink 23. A water pump 22 is installed at the end of one of the heat sinks 23, and a water inlet 24 is opened at the top of the water tank 2.

[0042] When the transformer box 1 is used in hot weather, the outside of the transformer box 1 will be exposed to sunlight. At this time, the transformer box 1 will generate a lot of heat. The accumulation of heat will continue to heat the air inside the transformer box 1, causing the temperature inside the dry-type transformer body 4 to rise. Therefore, it is necessary to cool the transformer box 1, start the water pump 22 to extract water from the heat pipe 21, and the water flows from the inside of the water tank 2 to the inside of the heat pipe 21. The transformer box 1 conducts heat to the heat pipe 21, and the water flowing inside the heat pipe 21 can take away the heat from the heat pipe 21. Then, the water flowing through the heat pipe 21 enters the interior of the heat sink 23, and the heat sink 23 dissipates the heat in the water to the outside. At this time, the heat dissipation by the heat dissipation fan 5 can take away the heat on the surface of the heat sink 23. Then, the water after the heat is dissipated passes through the heat pipe 21 on the other side, and the heat pipe 21 takes away the heat on the other side through the water flow. Finally, the water flows back to the inside of the water tank 2. At this time, the water temperature inside the water tank 2 increases, and at the same time, the water evaporates through the water inlet 24 to dissipate heat. This cycle can make it easier to cool the inner surface of the transformer box 1.

[0043] like Figures 1 to 6 As shown, two symmetrical sunshades 3 are arranged above the water tank 2, and both ends of the sunshades 3 are rotatably connected to support plates 32, and the bottom ends of the support plates 32 are fixedly connected to the water tank 2;

[0044] When used outdoors, the sunshade 3 can shield the top of the transformer box 1 and the water tank 2, reduce the sunlight exposure to the transformer box 1 and the water tank 2, and reduce the overall temperature of the transformer box 1.

[0045] like Figures 1 to 7 As shown, a support frame 6 is provided inside the water tank 2, and floating blocks 64 are fixed at both ends of the bottom of the support frame 6, and lifting columns 33 are fixed on both sides of the top of the support frame 6, and the top of the lifting column 33 is movably connected to the bottom end of the sun visor 3, and a sliding column 331 is fixed to the top of the lifting column 33, and a guide shell 34 is fixed to the bottom end of the sun visor 3, and the guide shell 34 is located above the lifting column 33, and the sliding column 331 is slidably connected to the inside of the guide shell 34;

[0046] During use, the floating block 64 will float on the water surface inside the water tank 2. As the water level changes, the floating block 64 will drive the support frame 6 to rise and fall inside the water tank 2. During the rise and fall, the support frame 6 will push the sun visor 3 to flip through the lifting column 33. The lifting column 33 can drive the sun visor 3 to flip through the sliding column 331 inside the guide shell 34.

[0047] When the water source inside the water tank 2 is sufficient, the support frame 6 is at the highest point inside the transformer box 1 due to the buoyancy of the floating block 64. At this time, the support frame 6 pushes the lifting column 33 to move upward and drives the sunshade 3 to flip upward. At this time, the sunshade 3 is Figure 5In the flipped V-shaped state, the sunshade 3 can guide a large part of the rainwater to the two sides of the transformer box 1 on rainy days;

[0048] When part of the water source in the water tank 2 is consumed, the floating block 64 will move downward with the water level. At this time, the support frame 6 drives the sunshade 3 to flip downward through the lifting column 33. However, due to the friction between the sunshades 3, they will be in a parallel state. At this time, the sunshade 3 is Figure 4 state;

[0049] When the water source in the water tank 2 is consumed to a lower state, the float 64 drives the support frame 6 to descend to the lowest position in the water tank 2. At this time, the support frame 6 pulls the sun visor 3 to flip through the lifting column 33. At this time, the sun visor 3 is in a Figure 6 In the middle V-shaped state, the sun visor 3 can guide rainwater to the top of the water inlet 24 on rainy days, so that the rainwater can enter the interior of the water tank 2 to replenish the water source.

[0050] like Figures 1 to 8 As shown, a plurality of mesh belts 61 are arranged at equal intervals inside the support frame 6, and a flip plate 62 is arranged on one side of the mesh belt 61. The flip plate 62 is used to fill the gap between two adjacent mesh belts 61, and the flip plate 62 located at the end is used to fill the gap between the mesh belt 61 and the inner side of the support frame 6;

[0051] In daily use, external objects may enter the interior of the water tank 2 from the water inlet 24. At this time, the mesh belt 61 and the flip plate 62 can filter out the external objects inside the support frame 6. The objects can be taken out during the maintenance process by the staff, which can prevent the pipe opening inside the water tank 2 from being blocked.

[0052] like Figures 1 to 8 As shown, the flip plate 62 is rotatably connected to the support frame 6, a lower limit block 623 is provided below the flip plate 62 away from the rotating shaft, and an upper limit block 622 is provided above the flip plate 62 away from the rotating shaft. The upper limit block 622 and the lower limit block 623 are both fixedly connected to the support frame 6, and a floating ball 621 is fixed to the middle of the bottom end of the flip plate 62, and the height of the bottom end of the floating ball 621 is flush with the height of the bottom end of the floating block 64;

[0053] When the water source in the water tank 2 is stored for a long time, algae are easy to grow. When the sun visors 3 are parallel to each other, the water barrier strips 31 will accumulate rainwater on the top of the sun visors 3. When the rainwater accumulates more and its weight is greater than the force of the sun visors 3 to fix the sun visors 3, the sun visors 3 will quickly flip over. Figure 6At this time, the water on the top of the sun visor 3 flows into the inside of the water tank 2 through the water inlet 24, and at the same time, the support frame 6 is pushed downward by the lifting column 33 when the sun visor 3 flips quickly. At this time, the support frame 6 drives the mesh belt 61 and the flip plate 62 downward, and the float 621 is pushed by the water surface to drive the flip plate 62 to flip. After the flip plate 62 flips, the water on the water surface surges from the gap between the flip plate 62 and the mesh belt 61 to the top of the mesh belt 61. At this time, the algae on the water surface are also placed above the mesh belt 61 with the water flow, and then the flip plate 62 is reset. At the same time, the upper limit block 622 and the lower limit block 623 can limit the flip plate 62, so that the algae can be collected to prevent the algae from clogging the pipe mouth.

[0054] like Figures 1 to 8 As shown, support shafts 611 are provided at both ends of the mesh belt 61, connecting shafts 612 are fixed between adjacent support shafts 611, and the support shafts 611 are rotatably connected to the support frame 6 through connecting blocks. A motor 613 is installed on one side of the support frame 6, and the motor 613 is fixedly connected to the ends of the adjacent support shafts 611. A cleaning push plate 63 is provided above the mesh belt 61, and the cleaning push plate 63 is fixedly connected to the inner side of the support frame 6.

[0055] After the mesh belt 61 filters the algae in the water, the algae will attach to the top of the mesh belt 61, but the attachment position will be blocked and cannot be filtered in subsequent use, so the motor 613 is turned on at a fixed time, and the rotation of the motor 613 drives the support shaft 611 to rotate. When the support shaft 611 rotates, it drives the mesh belt 61 to roll. When the mesh belt 61 rolls, it can drive the algae to move from the top of the mesh belt 61 toward the cleaning push plate 63. At this time, the cleaning push plate 63 can scrape off the algae on the top of the mesh belt 61 to prevent the algae from affecting the filtration of the water source by the mesh belt 61.

[0056] like Figures 1 to 10 As shown, a slag discharge pipe 7 is arranged above the mesh belt 61, and the slag discharge pipe 7 is fixed inside the water tank 2. A plurality of slag suction pipes 71 are arranged at the bottom end of the slag discharge pipe 7, and the position of the slag suction pipe 71 matches the mesh belt 61. A high-speed fan 73 is installed at one end of the slag discharge pipe 7, and a button 72 is fixed on one side of the bottom end of the slag discharge pipe 7, and the button 72 is located above the side of the support frame 6. A plurality of cutters are arranged inside the cleaning push plate 63, and a baffle plate 74 is arranged at one end of the slag discharge pipe 7 away from the high-speed fan 73. A connecting rod 741 is hinged at the top of the baffle plate 74, and the other end of the connecting rod 741 is fixedly connected to the slag discharge pipe 7, a connecting block is fixed at the top of the connecting rod 741, and a connecting block is also fixed at the top of the baffle plate 74, and a spring piece 742 is fixed between the connecting block of the baffle plate 74 and the connecting rod 741.

[0057] When the cleaning push plate 63 scrapes the algae on the top of the mesh belt 61, the cutter inside the cleaning push plate 63 will cut the algae into multiple small pieces of algae. When the water level inside the water tank 2 is high, the support frame 6 will rise accordingly. When the support frame 6 rises to a certain height, the button 72 will be pressed. At this time, the slag suction pipe 71 is above the cleaning push plate 63. At this time, the high-speed fan 73 starts to blow air into the slag discharge pipe 7. After the air circulates inside the slag discharge pipe 7, negative pressure will be generated inside the slag suction pipe 71. The slag suction pipe 71 will inhale air above the cleaning push plate 63. At this time, the algae Small pieces of algae will be sucked into the interior of the slag discharge pipe 7 along with the air, and at the same time, as the air is discharged to the outside, the algae inside the support frame 6 can be cleaned. When the slag discharge pipe 7 discharges small pieces of algae, the small pieces of algae will be sprayed out. If there are pedestrians or other objects nearby, they may cause damage. Therefore, when the slag discharge pipe 7 sprays out small pieces of algae, the baffle plate 74 will block them. When the baffle plate 74 is hit, it flips and drives the spring piece 742 to bend. The spring piece 742 can buffer the baffle plate 74, so that the small pieces of algae can fall downward, preventing the small pieces of algae from affecting the outside world.

[0058] like Figures 11 to 13 As shown, the two air outlet hoods 12 are both provided with guide plates 86 on one side close to the dry-type transformer body 4, the top and bottom ends of the guide plates 86 are both rotatably connected with support arms 861, the support arms 861 are fixedly connected to the air outlet hood 12, the top and bottom ends of the rotating shafts of the guide plates 86 are both fixed with rotating arms, a tension spring 862 is fixed between the rotating arms at the top ends, a pull rope 863 is fixed between the rotating arms at the bottom ends, the pull rope 863 passes through the guide hole of the lower support arm 861, and the end of 83 close to the winding device 85 side away from the guide plate 86 is fixedly connected to the traction rope 842, and the end of 83 away from the winding device 85 is fixedly connected to the moving frame 84 away from the winding device 85 side;

[0059] When the air outlet hood 12 inputs air flow into the transformer box body 1, the air flow will be directly blown to the outside of the dry-type transformer body 4. However, the area of ​​the dry-type transformer body 4 that can contact the air flow is small. Therefore, when the heat dissipation demand is high, the winding device 85 will wind up the traction rope 842. At this time, the traction rope 842 will drive the pull rope 863, and the pull rope 863 will pull the rotating arm of the guide plate 86. At this time, the two guide plates 86 will flip over. When flipping, the tension spring 862 will be pulled by the rotating arm at the top of the guide plate 86. At this time, the air flow input by the air outlet hood 12 will be dispersed to the positions of the heat conducting plates 8 on both sides through the guide plates 86. At this time, the heat conducting plates 8 can be directly in contact with the air flow, and the heat dissipation effect will be better. The states of the guide plates 86 on both sides are in opposite states. When the guide plate 86 at one end flips, the guide plate 86 at the other end returns to the initial state, which is more convenient for synchronous adjustment with the direction of air inlet and outlet of the two air outlet hoods 12.
