Description

Technical Field

[0001] This invention relates to the field of power transformer technology, specifically a power transformer with convenient heat dissipation. Background Technology

[0002] A power transformer is a static electrical device primarily used to transform an alternating current (AC) voltage (or current) of a certain value into one or more voltages (or currents) of different values ​​but with the same frequency. The basic working principle of a power transformer is based on electromagnetic induction, using an iron core and windings to achieve voltage and current transformation. A transformer consists of a primary coil, a secondary coil, and an iron core, utilizing the principle of electromagnetic induction to transfer electrical energy from the primary side to the secondary side. The transformer's turns ratio (the ratio of the voltage or current on the primary side to the voltage or current on the secondary side) is equal to the turns ratio; by changing the number of turns in the windings, voltage transformation can be achieved.

[0003] Some outdoor power transformers are widely used in urban power distribution, rural power grids, industrial and mining enterprises and other places that require power conversion. Although most power transformers have a conversion efficiency of over 99%, there are still some small losses, such as copper loss, core loss, hysteresis and eddy current loss. During operation, current passes through the transformer windings and generates an alternating electromagnetic field in the transformer. During this process, the windings and core will generate heat. These losses will cause the internal temperature of the transformer to rise.

[0004] The conventional heat dissipation method is oil-air natural cooling. When the temperature is high, the oil volume inside the power transformer increases and rises to the top of the oil tank, entering the heat sink around the transformer. By increasing the contact area with the air, natural air cooling is achieved. The cooled oil then flows back into the transformer. However, this heat dissipation method can only solve conventional heat dissipation requirements. In continuous high-temperature weather, the power load increases sharply, which can cause the power transformer to operate under overload. The temperature of the power transformer is very high and it is difficult to cool it down to the limit quickly, which may cause the transformer to be damaged due to overheating. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a power transformer with convenient heat dissipation. By driving the mechanism to move on a circular track, it not only achieves air cooling of the power transformer, but also enables water cooling by controlling the flow of water through the docking parts. It has two heat dissipation modes: single air cooling and combined air and water cooling. It can adjust to a suitable heat dissipation mode according to the temperature changes of the power transformer, which is highly targeted and has a good heat dissipation effect, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A power transformer with convenient heat dissipation includes a base, a water storage tank installed on the top outer wall of the base, and a transformer body fixedly connected to the bottom inner wall of the water storage tank by bolts. A ring track is fixedly connected to the top outer wall of the transformer body by screws, and a drive mechanism is provided on the outer wall of the ring track. A wind-cooling mechanism for ventilating and dissipating heat from the transformer body is provided on the top outer wall of the drive mechanism, and a water-cooling mechanism for water-cooling heat dissipation from the transformer body is provided on the top of the base. A connecting piece for controlling water flow is provided between the wind-cooling mechanism and the water-cooling mechanism. The water-cooling mechanism surrounds the top of the transformer body.

[0008] By driving the mechanism to move on the circular track, not only is air cooling of the power transformer achieved, but water cooling can also be achieved by controlling the flow of water through the docking parts. It has two heat dissipation modes: single air cooling and combined air cooling and water cooling. It can adjust to the appropriate heat dissipation mode according to the temperature changes of the power transformer, which is highly targeted and has a good heat dissipation effect.

[0009] The water cooling mechanism includes a filter assembly, a water pump, a water supply pipe, a ring water pipe, branch water pipes, T-shaped water pipes, spray nozzles, and a water receiving assembly. The filter assembly is installed on one side of the water storage tank, the water pump is installed at one end of the filter assembly, the water supply pipe is fixedly connected to the inner wall of the water pump outlet, the ring water pipe is located at the top of the water storage tank and is fixedly connected to the outer wall of one end of the water supply pipe, the branch water pipe is welded to the inner outer wall of the water supply pipe, the T-shaped water pipe is located at one end of the branch water pipe, and the spray nozzles are evenly distributed on the bottom outer wall of the T-shaped water pipe. The water receiving assembly is welded between the branch water pipe and the T-shaped water pipe. The branch water pipe includes multiple pipes that are evenly distributed around the top of the transformer body.

[0010] As a further embodiment of the present invention, the driving mechanism includes a mounting plate, a front drive wheel, a front auxiliary wheel, a servo motor, a pulley pair, and a rear auxiliary wheel. The mounting plate is disposed on the top of the annular track, and the front drive wheel and the front auxiliary wheel are rotatably connected to one side of the bottom outer wall of the mounting plate. The servo motor is fixedly connected to the bottom outer wall of the mounting plate by screws. The pulley pair is installed between the output shaft of the servo motor and the shaft of the front drive wheel. The rear auxiliary wheel is rotatably connected to the other side of the bottom outer wall of the mounting plate. The outer circumference inner wall and the inner side inner wall of the annular track are respectively provided with an outer ring groove and an inner ring groove. The front drive wheel and the front auxiliary wheel are slidably connected to the inner wall of the outer ring groove, and the rear auxiliary wheel is slidably connected to the inner wall of the inner ring groove.

[0011] Under the mutual influence of the water cooling mechanism and the connecting parts, once the temperature of the power transformer is too high, the connecting parts are moved by the drive mechanism. The electric push rod inside the connecting parts can push the conical push block upward. The conical push block pushes the pin upward, which controls the water-blocking column to move upward and the spring to compress. The water receiving component can be in a clear state. The water pump can deliver the purified water in the water storage tank to the spray head at the bottom of the T-shaped water pipe, thereby achieving the effect of directional water cooling. Compared with single air cooling, it can further accelerate the heat dissipation of oil temperature and further improve the heat dissipation effect of the power transformer. The oil temperature can be quickly cooled down to the limit value to avoid the problem of overheating and damage to the transformer.

[0012] As a further embodiment of the present invention, the air-cooling mechanism includes a mounting bracket welded to the top outer wall of the mounting plate, a fan fixedly connected to the inner wall of the mounting bracket by screws, and a wind-gathering shroud fixedly connected to the outer wall of one side of the mounting plate by screws. The fan includes two fans that are horizontally distributed on the inner wall of the mounting bracket, and the air outlet direction of the fans is towards the wind-gathering shroud side.

[0013] The servo motor drives the front drive wheel to rotate, which controls the entire mounting plate to slide along the track. After the temperature sensor moves to detect the high temperature position of the power transformer, the fan can blow cold air directly onto the heat dissipation plate of the power transformer under the action of the air shroud, which has the effect of rapid air cooling. Compared with traditional natural cooling, it can accelerate the heat dissipation of oil temperature and meet the daily heat dissipation requirements.

[0014] As a further embodiment of the present invention, the filtration assembly includes a filter frame, an external threaded ring, an internal threaded cover, and a filter element. The filter frame is installed on one side of the water storage tank and is interconnected with the water storage tank. The external threaded ring is disposed on the outer wall of one side of the filter frame, and the internal threaded cover is screwed onto the outer wall of the external threaded ring. The filter element is installed on the inner wall of the internal threaded cover, and the filter screen side of the filter element is disposed inside the filter frame. The filtration direction of the filter element is from the outside to the inside. During the water pumping process, the water inside the water storage tank first flows to the filter element, which purifies the water by filtering out particulate impurities. This prevents impurities from flowing with the water into the spray head and causing blockage, effectively improving the service life of the water-cooled equipment.

[0015] As a further embodiment of the present invention, the water receiving assembly includes a vertical pipe, a water-blocking column, a pin, and a spring. The vertical pipe is welded between the branch water pipe and the T-shaped water pipe. The water-blocking column is slidably connected to the inner wall of the vertical pipe. The pin is welded to the bottom outer wall of the water-blocking column and slidably connected to the inner wall of the vertical pipe. One end of the spring is fixedly connected to the top inner wall of the vertical pipe, and the other end is fixedly connected to the bottom inner wall of the water-blocking column. The length of the water-blocking column is longer than the inner diameter of both the branch water pipe and the T-shaped water pipe. Under normal conditions, the water-blocking column is pushed downwards by the spring, thus controlling its position below the vertical pipe to block the water passage between the branch water pipe and the T-shaped water pipe, preventing fluid flow. When the pin moves upwards, the water-blocking column also moves upwards, compressing the spring. At this time, the water passage between the branch water pipe and the T-shaped water pipe is unobstructed, allowing water in the reservoir to flow towards the spray head.

[0016] As a further embodiment of the present invention, the connecting component includes an electric push rod fixedly connected to the top outer wall of the mounting bracket by screws, a connecting plate mounted on the piston rod of the electric push rod, and a conical push block fixedly connected to the top outer wall of the connecting plate by screws. The top outer wall of the conical push block has a ball groove, and the arc surface of the bottom of the push pin is in close contact with the inner wall of the ball groove. The electric push rod can push the connecting plate upwards, thereby controlling the conical push block to push the push pin, thus facilitating unobstructed water flow in the water receiving assembly.

[0017] As a further embodiment of the present invention, a second servo motor is fixedly connected to the bottom of one side of the outer wall of the wind-collecting hood by screws, and the output shaft of the second servo motor is fixedly connected to a lead screw via a coupling. A lifting plate is screwed onto the outer wall of the lead screw, and adjacent thermometers are fixedly connected to the top outer wall of the lifting plate by screws. A guide rod is fixedly connected to the other side of the outer wall of the wind-collecting hood, and one end of the lifting plate is slidably connected to the outer wall of the guide rod. By rotating the lead screw driven by the second servo motor, the lifting plate can be raised and lowered, thereby moving the thermometers. The thermometers can be used to detect the surface temperature of the transformer body in real time.

[0018] As a further embodiment of the present invention, a sunshade is installed on one side of the top outer wall of the base, and servo motor one, servo motor two, fan, electric actuator, and water pump are all located inside the sunshade. The sunshade serves to provide shade for the servo motor one, servo motor two, fan, electric actuator, and water pump.

[0019] As a further embodiment of the present invention, symmetrically distributed upper supports are welded to one side of the outer wall of the annular water pipe, with one end of the upper supports welded to the top outer wall of the sunshade. Symmetrically distributed lower supports are welded to the other side of the outer wall of the annular water pipe, with one end of the lower supports fixedly connected to the top outer wall of the base. Since the annular water pipe is an important water supply component, the lower and upper supports can provide support for the annular water pipe, enabling it to be stably installed on top of the transformer body.

[0020] As a further embodiment of the invention, a ventilation mesh is installed on the side of the mounting bracket away from the wind concentrator, and the fan is positioned between the ventilation mesh and the wind concentrator. The ventilation mesh is used to block large solid floating objects, preventing impurities from affecting the normal operation of the fan.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The power transformer of the present invention, which facilitates heat dissipation, moves on a circular track through a drive mechanism. It not only achieves air cooling of the power transformer, but also controls the flow of water through the docking parts, thereby achieving water cooling. It has two heat dissipation modes: single air cooling and combined air cooling and water cooling. It can adjust to the appropriate heat dissipation mode according to the temperature change of the power transformer, which is highly targeted and has a good heat dissipation effect.

[0023] 2. The power transformer of the present invention with convenient heat dissipation has a drive mechanism in which a servo motor drives the front drive wheel to rotate, which can control the entire mounting plate to slide along the track. After the temperature measuring instrument moves to detect the high temperature position of the power transformer, the fan can blow cold air directly onto the heat dissipation plate of the power transformer under the action of the wind shroud, which has the effect of rapid air cooling. Compared with traditional natural cooling, it can accelerate the heat dissipation of oil temperature and meet the daily heat dissipation requirements.

[0024] 3. The power transformer of the present invention, which facilitates heat dissipation, allows for the following process: under the interaction of the water cooling mechanism and the connecting parts, if the temperature of the power transformer becomes too high, the driving mechanism moves the connecting parts. The electric push rod inside the connecting parts can push the conical push block upwards. The conical push block pushes the pin upwards, which controls the water-blocking column to move upwards and compresses the spring. The water receiving component can then be in a clear state. The water pump can deliver the purified water from the water storage tank to the spray head at the bottom of the T-shaped water pipe, thereby achieving the effect of directional water cooling. Compared with single air cooling, this method can further accelerate oil temperature dissipation and further improve the heat dissipation effect of the power transformer. The oil temperature can be quickly cooled down to a limited value, avoiding the problem of overheating and damage to the transformer. Attached Figure Description

Detailed Implementation

[0036] Please see Figures 1-4 In this embodiment of the invention, a power transformer with convenient heat dissipation includes a base 1. A water storage tank 2 is installed on the top outer wall of the base 1, and a transformer body 3 is fixedly connected to the bottom inner wall of the water storage tank 2 by bolts. A ring track 4 is fixedly connected to the top outer wall of the transformer body 3 by screws, and a drive mechanism 5 is provided on the outer wall of the ring track 4. A wind-cooling mechanism 6 for ventilating and dissipating heat from the transformer body 3 is provided on the top outer wall of the drive mechanism 5, and a water-cooling mechanism 7 for water-cooling heat dissipation from the transformer body 3 is provided on the top of the base 1. A connecting piece 8 for controlling water flow is provided between the wind-cooling mechanism 6 and the water-cooling mechanism 7. The water-cooling mechanism 7 surrounds the top of the transformer body 3.

[0037] By moving the drive mechanism 5 on the circular track 4, not only is air cooling of the power transformer achieved, but the water flow can also be controlled by the docking part 8 to achieve water cooling. It has two heat dissipation modes: single air cooling and air cooling combined with water cooling. It can adjust to the appropriate heat dissipation mode according to the temperature change of the power transformer, which is highly targeted and has a good heat dissipation effect.

[0038] Please see Figures 6-8In this embodiment of the invention, the water cooling mechanism 7 includes a filter assembly 71, a water pump 72, a water supply pipe 73, an annular water pipe 74, a branch water pipe 75, a T-shaped water pipe 76, a spray nozzle 77, and a water receiving assembly 78. The filter assembly 71 is installed on one side of the water storage tank 2, the water pump 72 is installed at one end of the filter assembly 71, the water supply pipe 73 is fixedly connected to the inner wall of the outlet of the water pump 72, the annular water pipe 74 is located at the top of the water storage tank 2 and is fixedly connected to the outer wall of one end of the water supply pipe 73, the branch water pipe 75 is welded to the inner outer wall of the water supply pipe 73, the T-shaped water pipe 76 is located at one end of the branch water pipe 75, and the spray nozzles 77 are evenly distributed on the bottom outer wall of the T-shaped water pipe 76. The water receiving assembly 78 is welded between the branch water pipe 75 and the T-shaped water pipe 76. The branch water pipe 75 includes multiple pipes that are evenly distributed around the top of the transformer body 3.

[0039] Under the mutual influence of the water cooling mechanism 7 and the docking part 8, once the temperature of the power transformer is too high, the driving mechanism 5 drives the docking part 8 to move. The electric push rod 81 inside the docking part 8 can push the conical push block 83 upward. The conical push block 83 pushes the push pin 783 upward, which can control the water blocking column 782 to move upward and the spring 784 to compress. The water receiving component 78 can be in a clear state. The water pump 72 can transport the purified water inside the water storage tank 2 to the spray head 77 at the bottom of the T-shaped water pipe 76, thereby achieving the effect of directional water cooling. Compared with single air cooling, it can further accelerate the heat dissipation of oil temperature and further improve the heat dissipation effect of the power transformer. The oil temperature can be quickly cooled down to the limit value to avoid the problem of overheating and damage to the transformer.

[0040] Please see Figures 4-5 In this embodiment of the invention, the driving mechanism 5 includes a mounting plate 51, a front drive wheel 52, a front auxiliary wheel 53, a servo motor 54, a pulley pair 55, and a rear auxiliary wheel 56. The mounting plate 51 is disposed on the top of the annular track 4, and the front drive wheel 52 and the front auxiliary wheel 53 are rotatably connected to one side of the bottom outer wall of the mounting plate 51. The servo motor 54 is fixedly connected to the bottom outer wall of the mounting plate 51 by screws. The pulley pair 55 is installed between the output shaft of the servo motor 54 and the shaft of the front drive wheel 52. The rear auxiliary wheel 56 is rotatably connected to the other side of the bottom outer wall of the mounting plate 51. The outer circumferential inner wall and the inner side inner wall of the annular track 4 are respectively provided with an outer ring groove and an inner ring groove. The front drive wheel 52 and the front auxiliary wheel 53 are slidably connected to the inner wall of the outer ring groove, and the rear auxiliary wheel 56 is slidably connected to the inner wall of the inner ring groove.

[0041] Please see Figures 4-5In this embodiment of the invention, the air-cooling mechanism 6 includes a mounting bracket 61 welded to the top outer wall of the mounting plate 51, a fan 62 fixedly connected to the inner wall of the mounting bracket 61 by screws, and a wind-gathering shroud 63 fixedly connected to the outer wall of one side of the mounting plate 51 by screws. The fan 62 includes two fans that are horizontally distributed on the inner wall of the mounting bracket 61, and the air outlet direction of the fan 62 is towards the wind-gathering shroud 63.

[0042] In the drive mechanism 5, the servo motor 54 drives the front drive wheel 52 to rotate, which can control the entire mounting plate 51 to slide along the circular track 4. After the temperature measuring instrument 12 moves to detect the high temperature position of the power transformer, under the action of the wind shroud 63, the fan 62 can blow cold air directly onto the heat dissipation plate of the power transformer, which has the effect of rapid air cooling. Compared with traditional natural cooling, it can accelerate the heat dissipation of oil temperature and meet the daily heat dissipation requirements.

[0043] Please see Figure 7 In this embodiment of the invention, the filter assembly 71 includes a filter frame 711, an external threaded ring 712, an internal threaded cover 713, and a filter element 714. The filter frame 711 is installed on one side of the water storage tank 2 and is interconnected with the water storage tank 2. The external threaded ring 712 is disposed on the outer wall of one side of the filter frame 711. The internal threaded cover 713 is screwed onto the outer wall of the external threaded ring 712. The filter element 714 is installed on the inner wall of the internal threaded cover 713, and the filter screen side of the filter element 714 is disposed inside the filter frame 711. The filtration direction of the filter element 714 is from the outside to the inside.

[0044] During the water pumping process, the water inside the water storage tank 2 will first flow to the filter element 714. The filter element 714 plays the role of purifying water quality and can filter particulate impurities in the water, preventing impurities from flowing with the water flow into the spray head 77 and causing the spray head 77 to become clogged. This can effectively improve the service life of the water-cooled equipment.

[0045] Please see Figures 9-10 In this embodiment of the invention, the water receiving assembly 78 includes a vertical pipe 781, a water-blocking column 782, a pin 783, and a spring 784. The vertical pipe 781 is welded between the branch water pipe 75 and the T-shaped water pipe 76. The water-blocking column 782 is slidably connected to the inner wall of the vertical pipe 781. The pin 783 is welded to the bottom outer wall of the water-blocking column 782 and slidably connected to the inner wall of the vertical pipe 781. One end of the spring 784 is fixedly connected to the top inner wall of the vertical pipe 781, and the other end of the spring 784 is fixedly connected to the bottom inner wall of the water-blocking column 782. The length of the water-blocking column 782 is longer than the inner diameter of the branch water pipe 75 and the T-shaped water pipe 76.

[0046] Under normal conditions, the water-blocking column 782 is pushed downward by the spring 784, thereby controlling the water-blocking column 782 to be located below the vertical pipe 781 to block the water passage between the branch water pipe 75 and the T-shaped water pipe 76, preventing fluid from passing through. When the ejector pin 783 moves upward, the water-blocking column 782 also moves upward, and the spring 784 is compressed. At this time, the water passage between the branch water pipe 75 and the T-shaped water pipe 76 is unobstructed, and the water in the water storage tank 2 can flow to the spray head 77 side.

[0047] Please see Figures 8-9 In this embodiment of the invention, the docking component 8 includes an electric push rod 81 fixedly connected to the top outer wall of the mounting bracket 61 by screws, a connecting plate 82 mounted on the piston rod of the electric push rod 81, and a conical push block 83 fixedly connected to the top outer wall of the connecting plate 82 by screws. The top outer wall of the conical push block 83 is provided with a ball groove, and the arc surface of the bottom of the push pin 783 is in close contact with the inner wall of the ball groove.

[0048] The electric push rod 81 can push the connecting plate 82 upward, thereby controlling the conical push block 83 to push the push pin 783, thus facilitating the smooth flow of water in the water receiving component 78.

[0049] Please see Figure 5 In this embodiment of the invention, a servo motor 2 9 is fixedly connected to the bottom of one side of the outer wall of the wind-gathering hood 63 by screws, and the output shaft of the servo motor 2 9 is fixedly connected to a lead screw 10 by a coupling. A lifting plate 11 is screwed onto the outer wall of the lead screw 10, and adjacent temperature measuring instruments 12 are fixedly connected to the top outer wall of the lifting plate 11 by screws. A guide rod 13 is fixedly connected to the other side of the outer wall of the wind-gathering hood 63, and one end of the lifting plate 11 is slidably connected to the outer wall of the guide rod 13.

[0050] The servo motor 29 drives the lead screw 10 to rotate, which controls the lifting plate 11 to rise and fall, thereby driving the temperature measuring instrument 12 to move. The temperature measuring instrument 12 can detect the surface temperature of the transformer body 3 in real time.

[0051] Please see Figure 2 In this embodiment of the invention, a sunshade 14 is installed on one side of the top outer wall of the base 1, and the servo motor 54, servo motor 9, fan 62, electric push rod 81 and water pump 72 are all located inside the sunshade 14.

[0052] The sunshade 14 serves to provide shade for equipment such as servo motor 1 54, servo motor 2 9, fan 62, electric actuator 81, and water pump 72.

[0053] Please see Figures 2-3In this embodiment of the invention, an upper support 15 is symmetrically distributed on one side of the outer wall of the annular water pipe 74, and one end of the upper support 15 is welded to the top outer wall of the sunshade 14. A lower support 16 is symmetrically distributed on the other side of the outer wall of the annular water pipe 74, and one end of the lower support 16 is fixedly connected to the top outer wall of the base 1.

[0054] Since the annular water pipe 74 is an important water supply component, the lower support 16 and the upper support 15 can provide support for the annular water pipe 74, so that the annular water pipe 74 can be stably installed on the top of the transformer body 3.

[0055] Please see Figures 4-5 In this embodiment of the invention, a ventilation net is installed on the side of the mounting bracket 61 away from the wind concentrator 63, and a fan 62 is disposed between the ventilation net and the wind concentrator 63.

[0056] The ventilation screen is used to block large solid floating objects and prevent impurities from affecting the normal operation of the fan 62.

[0057] The working principle of this invention is as follows: The transformer body 3 is installed above the water storage tank 2, and a ring track 4 is installed around the top of the water storage tank 2. Under normal circumstances, the electrical equipment is installed inside the sunshade 14. When the electrical load of the transformer body 3 increases, causing the temperature to rise, the servo motor 1 54 can drive the front drive wheel 52 to rotate, thereby controlling the mounting plate 51 to rotate around the center of the ring track 4. At this time, the servo motor 2 9 can drive the lead screw 10 to rotate, which can control the temperature measuring instrument 12 to rise and fall. The temperature measuring instrument 12 can detect the surface temperature of the transformer body 3 in real time. After determining the high temperature position of the transformer body 3, the fan 62 can blow cold air directly onto the heat dissipation plate of the power transformer to complete the first-level air cooling effect.

[0058] In hot weather, when the temperature measuring instrument 12 detects that the surface temperature of the transformer body 3 is too high, on the one hand, the fan 62 blows air to cool it down, and on the other hand, the electric push rod 81 pushes the connecting plate 82 upward to control the conical push block 83 to push the pin 783. At this time, the water blocking column 782 moves upward and the spring 784 is compressed. The vertical pipe 781 changes from the original blocked state to the unblocked state. After the water in the water storage tank 2 is purified by the filter element 714, the water pump 72 can deliver the water to the spray head 77 at the bottom of the T-shaped water pipe 76. The spray head 77 sprays cold water downward to achieve water cooling of the transformer body 3, thus completing the two-stage heat dissipation mode of combining air cooling and water cooling.
