Description

Technical Field

[0001] The present invention relates to the technical field of voltage transformers, and specifically to a voltage transformer with a fast heat dissipation function. Background Art

[0002] As a key measurement device in the power system, the long-term operation stability of the voltage transformer directly affects the monitoring accuracy of the power grid. With the advancement of the construction of smart grids, the problem of temperature rise of traditional voltage transformers under high-load conditions has become increasingly prominent.

[0003] There is a disclosed heat dissipation type voltage transformer in the prior art (Patent No.: CN201711387585.7), which dissipates heat through a fan, cannot achieve fast heat dissipation, and the use environment is restricted and cannot be used in complex environments such as outdoors. Therefore, the existing voltage transformers mainly have the following problems: (1) cannot achieve fast heat dissipation, (2) the local temperature of the transformer is too high, and the transformer cannot be evenly cooled. Summary of the Invention

[0004] The purpose of the present invention is to provide a voltage transformer with a fast heat dissipation function to solve the problems proposed in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A voltage transformer with a fast heat dissipation function, including an insulating housing, a transformer body is arranged inside the insulating housing, an isolation cover is arranged outside the transformer body, a cooling plate is installed above the isolation cover, a refrigeration plate is installed inside the cooling plate, the cooling plate is sequentially connected with an output pipe, an intermediate pipe and an input pipe, the intermediate pipe is connected with a scroll tube, a collection plate is installed below the isolation cover, a temperature measurement plate is installed inside the collection plate, and shock-absorbing springs are installed at the four corners of the insulating housing.

[0006] The insulating housing is provided with a liquid injection port, an air inlet and a liquid discharge port. The air inlet and the liquid discharge port are located on both sides of the liquid injection port. A storage tank is installed on one side of the transformer body, and the storage tank is installed on the insulating housing. The inlet of the storage tank is connected with the liquid injection port through a pipeline, and the outlet of the storage tank is connected with the input pipe through a pipeline. A coolant is arranged inside the storage tank. The input pipe is connected in series with a delivery pump, and the delivery pump transports the coolant in the storage tank into the input pipe, so that the coolant flows at a high speed in the input pipe. The storage tank stores and buffers the coolant to avoid excessive impact of the coolant and affect the normal operation of the transformer body.

[0007] The input pipe, the intermediate pipe, the output pipe and the vortex pipe are all arranged on the insulating housing. The diameter of the intermediate pipe is smaller than that of the input pipe and the output pipe. An electromagnetic valve and a flow meter are installed in the output pipe, and the electromagnetic valve and the flow meter in the output pipe are electrically connected to the control system. The vortex pipe is connected to the air inlet through a pipeline. The vortex pipe is distributed in a planar thread. A plurality of filter plates are rotatably arranged on the inner wall of the vortex pipe in sequence through torsion springs. Filter meshes are arranged on the plurality of filter plates, and the diameters of the plurality of filter meshes gradually decrease in sequence; When the vortex pipe performs dust removal work, air and dust are inhaled from one end of the vortex pipe. After passing through the vortex pipe and a plurality of filter meshes for dust removal, the air is discharged from the other end of the vortex pipe and collides with the coolant at high speed to form water mist, so as to quickly dissipate heat from the transformer body through the aerosol; When the vortex pipe is cleaned, the coolant is transported into the input pipe through the coolant transport system and the transport pump. The control system simultaneously closes the electromagnetic valve in the output pipe. The coolant enters the storage tank through the liquid injection port. The transport pump works intermittently to extract the coolant in the storage tank into the input pipe, so that the coolant enters the input pipe intermittently, forming an impact of the coolant, so as to clean the filter mesh through the intermittent coolant; The intermittently moving coolant enters the vortex pipe through the input pipe and the intermediate pipe. Since a large amount of dust is deposited on the filter mesh, the resistance of the coolant passing through the filter mesh is relatively large. The coolant will push the filter plate and the filter mesh to flip a certain angle. While the filter plate flips, the torsion spring is compressed. The filter plate flips a certain angle and impacts on the vortex pipe; afterwards, the dust on the filter mesh becomes less after being washed by the coolant, and the resistance of the coolant passing through the filter mesh becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate and the filter mesh to flip a certain angle in the reverse direction, and reversely pushes the filter plate to impact on the vortex pipe again. Through the intermittent movement of the coolant, multiple impacts of the filter plate are realized, and the dust on the filter mesh is impacted and dropped. After the coolant washes a plurality of filter meshes at the same time, the washed coolant is discharged from the vortex pipe into the air inlet and discharged from the air inlet of the voltage transformer, realizing the cleaning process of the plurality of filter meshes.

[0008] The cooling plate and the collection plate are both installed on the insulating housing. A plurality of cooling channels and a plurality of collection channels are respectively arranged in the cooling plate and the collection plate. A plurality of spraying ports and a plurality of collection ports are respectively arranged on the opposite sides of the cooling plate and the collection plate. The plurality of spraying ports and collection ports face the transformer body. One ends of the plurality of cooling channels are all communicated with the output pipe, and the other ends of the plurality of cooling channels are respectively communicated with the plurality of spraying ports. One ends of the plurality of collection channels are all communicated with the plurality of collection ports, and the other ends of the plurality of collection channels are communicated with the drain port through a pipeline. The liquid injection port and the drain port are both connected to the coolant transport system. A flow control valve and a flow meter are installed in each of the plurality of cooling channels, and the flow control valve and the flow meter in the cooling channels are both electrically connected to the control system; A plurality of the refrigeration plates are provided, and the plurality of refrigeration plates are sequentially arranged in the cooling flow channel.

[0009] A collection cylinder is arranged on the upper side of the collection plate. The collection cylinder is in close contact with the inner wall of the insulating housing. A plurality of temperature measurement plates are provided, and the plurality of temperature measurement plates are sequentially arranged in a plurality of collection flow channels.

[0010] The plurality of spraying ports and the plurality of collection ports are opposite to each other. The control system adjusts the opening degree of the flow control valves in the plurality of cooling flow channels according to the temperature data detected by the plurality of temperature measurement plates.

[0011] A plurality of displacement sensors are arranged on the insulating housing. The displacement sensors are used to detect the displacement of the insulating housing. Spiral grooves are arranged at the four corners of the insulating housing. Lifting shafts are threadedly connected in the spiral grooves. The lifting shafts and the spiral grooves form a threaded seal. The upper ends of the lifting shafts penetrate through the insulating housing and are provided with handwheels. Scales are arranged on the handwheels. The lower ends of the lifting shafts are connected with shock-absorbing springs. The shock-absorbing springs are located in the spiral grooves. Contact plates are rotatably arranged at the lower ends of the shock-absorbing springs. Telescopic shafts are connected between the contact plates and the lifting shafts. The telescopic shafts are of a telescopic structure. The contact plates are in contact with the ground.

[0012] The damping effect of the voltage transformer is designed to be adjustable to face different usage scenarios. The staff rotates the handwheel to the set scale. The handwheel drives the lifting shaft to rotate. The lifting shaft drives the shock-absorbing spring to rotate. While the shock-absorbing spring rotates, it moves downward in the spiral groove. At this time, the number of turns of the shock-absorbing spring between the bottom of the insulating housing and the contact plate increases, and the damping effect becomes stronger.

[0013] Connection plates and two semiconductors are arranged on both the temperature measurement plates and the refrigeration plates. The connection plates are made of metal. The materials of the two semiconductors are different. One ends of the two semiconductors are both connected to the connection plates. The two semiconductors are electrically connected to the control system through wires; The connection plates and the two semiconductors on the temperature measurement plates are the hot ends of the Seebeck effect. The connection plates and the two semiconductors on the refrigeration plates are the refrigeration ends of the Peltier effect.

[0014] The isolation cover is made of a heat-conducting material. The isolation cover conducts the heat of the transformer body outward to facilitate the rapid heat dissipation of the transformer body.

[0015] A window is arranged on the insulating housing. The window is made of a transparent material.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Increase the cooling area by means of aerosol coolant to achieve rapid cooling. Air is successively sucked into the middle pipe through the vortex tube. After being sucked through the middle pipe, the air collides with the high-speed coolant to form an aerosol, and then is transported to the cooling flow channel through the output pipe; the control system cools the aerosol coolant in the cooling flow channel through the refrigeration end, so that the aerosol coolant is cooled to the set temperature. The cooled aerosol coolant is sprayed on the isolation cover from multiple spray ports. The aerosol coolant increases the contact area with the isolation cover, improves the cooling effect, and enables the rapid heat dissipation of the transformer body.

[0017] 2. Detect the coolant temperature at different positions of the transformer body, and then adjust the coolant flow rate to avoid local overheating of the transformer body. When the control system obtains the temperatures of the coolant in multiple collection flow channels, the control system adjusts the opening degree of the flow control valve in the cooling flow channel according to the temperatures of the coolant in the multiple collection flow channels; when the temperature in the collection flow channel is higher than the set temperature, the control system increases the opening degree of the flow control valve in the cooling flow channel directly above the collection flow channel, so that the coolant flow rate in the cooling flow channel directly above the collection flow channel becomes larger, so as to uniformly cool the isolation cover and the transformer body, avoid the problem of local overheating of the isolation cover and the transformer body, achieve targeted cooling of the isolation cover and the transformer body, and improve the cooling effect; afterwards, the control system processes the current generated by the Seebeck effect through voltage transformation and rectification, etc., and uses it for the cooling of the refrigeration plate. While realizing detection, the energy consumption of the voltage transformer can be reduced.

[0018] 3. Clean the filter screen to ensure the filtering effect of the filter screen. The intermittently moving coolant enters the vortex tube through the input pipe and the middle pipe. Due to a large amount of dust deposited on the filter screen, the resistance of the coolant passing through the filter screen is relatively large. The coolant will push the filter plate and the filter screen to turn a certain angle. While the filter plate turns, the torsion spring is compressed. The filter plate turns a certain angle and impacts on the vortex tube; afterwards, the dust on the filter screen is washed away by the coolant and becomes less, and the resistance of the coolant passing through the filter screen becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate and the filter screen to turn a certain angle in the reverse direction, and reversely pushes the filter plate to impact on the vortex tube again. Through the intermittent movement of the coolant, multiple impacts of the filter plate are realized, and the dust on the filter screen is knocked down. After the coolant flushes multiple filter screens at the same time, the flushed coolant is discharged from the vortex tube into the air inlet and discharged from the air inlet of the voltage transformer, realizing the cleaning treatment of multiple filter screens.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Embodiment: As Figures 1-9 shown, the present invention provides a technical solution of a voltage transformer with a fast heat dissipation function, including an insulating housing 11, a transformer body 12 is arranged inside the insulating housing 11, an isolation cover 13 is arranged outside the transformer body 12, the isolation cover 13 is made of a heat-conducting material, and the isolation cover 13 conducts the heat of the transformer body 12 outwards to facilitate the fast heat dissipation of the transformer body 12. A cooling plate 2 is installed above the isolation cover 13, a refrigeration plate 201 is installed inside the cooling plate 2, the cooling plate 2 is sequentially connected with an output pipe 21, an intermediate pipe 22 and an input pipe 23, the intermediate pipe 22 is connected with a vortex tube 24, a collection plate 3 is installed below the isolation cover 13, a temperature-measuring plate 31 is installed inside the collection plate 3, shock-absorbing springs 14 are installed at the four corners of the insulating housing 11, and a window 1 is arranged on the insulating housing 11, and the window 1 is made of a transparent material.

[0023] The insulating housing 11 is provided with a liquid injection port 111, an air inlet 112 and a liquid discharge port 113. The air inlet 112 and the liquid discharge port 113 are located on both sides of the liquid injection port 111. On one side of the transformer core body 12, a storage tank 15 is installed. The storage tank 15 is installed on the insulating housing 11. The inlet of the storage tank 15 is connected to the liquid injection port 111 through a pipeline, and the outlet of the storage tank 15 is connected to the input pipe 23 through a pipeline. A coolant is provided in the storage tank 15. A delivery pump (not shown in the figure) is connected in series to the input pipe 23. The delivery pump delivers the coolant in the storage tank 15 into the input pipe 23, so that the coolant flows at a high speed in the input pipe 23. The storage tank 15 stores and buffers the coolant, avoiding excessive impact of the coolant and affecting the normal operation of the transformer core body 12.

[0024] The input pipe 23, the intermediate pipe 22, the output pipe 21 and the vortex tube 24 are all arranged on the insulating housing 11. The diameter of the intermediate pipe 22 is smaller than the diameters of the input pipe 23 and the output pipe 21. An electromagnetic valve and a flowmeter are installed in the output pipe 21. The electromagnetic valve and the flowmeter in the output pipe 21 are electrically connected to the control system. The vortex tube 24 is connected to the air inlet 112 through a pipeline. The vortex tube 24 is distributed in a planar spiral. A plurality of filter plates 241 are sequentially rotatably arranged on the inner wall of the vortex tube 24 through torsion springs. Filter meshes 242 are arranged on the plurality of filter plates 241. The diameters of the plurality of filter meshes 242 gradually decrease in sequence; When the vortex tube 24 performs dust removal, air and dust are inhaled through one end of the vortex tube 24. After being dust-removed by the vortex tube 24 and the plurality of filter meshes 242, the air is discharged from the other end of the vortex tube 24 and collides with the coolant at a high speed to form water mist, so as to quickly dissipate heat from the transformer core body 12 through the water mist; When the vortex tube 24 is cleaned, the coolant is delivered into the input pipe 23 through the coolant delivery system and the delivery pump. The control system simultaneously closes the electromagnetic valve in the output pipe 21. The coolant enters the storage tank 15 through the liquid injection port 111. The delivery pump works intermittently, extracting the coolant in the storage tank 15 into the input pipe 23, so that the coolant intermittently enters the input pipe 23, forming an impact of the coolant, so as to clean the filter mesh 242 through the intermittent coolant; The intermittently moving coolant enters the vortex tube 24 through the input pipe 23 and the intermediate pipe 22. Since a large amount of dust is deposited on the filter screen 242, the resistance of the coolant passing through the filter screen 242 is relatively large. The coolant will push the filter plate 241 and the filter screen 242 to flip by a certain angle. While the filter plate 241 flips, it compresses the torsion spring. The filter plate 241 flips by a certain angle and impacts on the vortex tube 24. After that, the dust on the filter screen 242 is washed away by the coolant and becomes less, and the resistance of the coolant passing through the filter screen 242 becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate 241 and the filter screen 242 to flip in the reverse direction by a certain angle, and reversely pushes the filter plate 241 to impact on the vortex tube 24 again. Through the multiple impacts of the intermittently moving coolant on the filter plate 241, the dust on the filter screen 242 is impacted and dropped. After the coolant flushes multiple groups of filter screens 242 at the same time, the flushed coolant is discharged from the vortex tube 24 into the air inlet 112 and discharged from the air inlet 112 to the potential transformer, realizing the cleaning treatment of multiple groups of filter screens 242.

[0025] The cooling plate 2 and the collecting plate 3 are both installed on the insulating housing 11. Multiple groups of cooling channels and multiple groups of collecting channels are respectively arranged in the cooling plate 2 and the collecting plate 3. Multiple groups of spraying ports 202 and multiple groups of collecting ports 203 are respectively arranged on the opposite sides of the cooling plate 2 and the collecting plate 3. The multiple groups of spraying ports 202 and the collecting ports 203 are facing the transformer body 12. One ends of the multiple groups of cooling channels are all connected to the output pipe 21, and the other ends of the multiple groups of cooling channels are respectively connected to the multiple groups of spraying ports 202. One ends of the multiple groups of collecting channels are all connected to the multiple groups of collecting ports 203, and the other ends of the multiple groups of collecting channels are connected to the drain port 113 through pipes. The injection port 111 and the drain port 113 are both connected to the coolant delivery system. Flow control valves and flow meters are installed in the multiple groups of cooling channels, and the flow control valves and flow meters in the cooling channels are electrically connected to the control system; Multiple groups of refrigeration plates 201 are provided, and the multiple groups of refrigeration plates 201 are sequentially arranged in the cooling channels; A collecting cylinder 301 is arranged on the upper side of the collecting plate 3, and the collecting cylinder 301 is closely attached to the inner wall of the insulating housing 11; Multiple groups of temperature measuring plates 31 are provided, and the multiple groups of temperature measuring plates 31 are sequentially arranged in the multiple groups of collecting channels; The multiple groups of spraying ports 202 and the multiple groups of collecting ports 203 are facing each other. The control system adjusts the opening degree of the flow control valves in the multiple groups of cooling channels according to the temperature data detected by the multiple groups of temperature measuring plates 31.

[0026] A plurality of displacement sensors are provided on the insulating housing 11. The displacement sensors are used to detect the displacement of the insulating housing 11. There are spiral grooves at the four corners of the insulating housing 11. A lifting shaft 16 is threadedly connected in the spiral grooves. The lifting shaft 16 and the spiral grooves form a threaded seal. The upper end of the lifting shaft 16 passes through the insulating housing 11 and is provided with a handwheel 161. A scale is provided on the handwheel 161. The lower end of the lifting shaft 16 is connected to a shock-absorbing spring 14. The shock-absorbing spring 14 is located in the spiral groove. A contact plate 17 is rotatably provided at the lower end of the shock-absorbing spring 14. A telescopic shaft (not shown in the figure) is connected between the contact plate 17 and the lifting shaft 16. The telescopic shaft is a telescopic structure. The contact plate 17 is in contact with the ground.

[0027] The damping effect of the voltage transformer is designed to be adjustable to face different usage scenarios. The staff rotates the handwheel 161 to the set scale. The handwheel 161 drives the lifting shaft 16 to rotate. The lifting shaft 16 drives the shock-absorbing spring 14 to rotate. While the shock-absorbing spring 14 rotates, it moves downward in the spiral groove. At this time, the number of turns of the shock-absorbing spring 14 between the bottom of the insulating housing 11 and the contact plate 17 increases, and the damping effect becomes stronger.

[0028] Both the temperature measuring plate 31 and the refrigerating plate 201 are provided with connecting plates and two kinds of semiconductors. The connecting plates are made of metal. The materials of the two kinds of semiconductors are different. One end of each of the two kinds of semiconductors is connected to the connecting plate. The two kinds of semiconductors are electrically connected to the control system through wires; the connecting plate and the two kinds of semiconductors on the temperature measuring plate 31 are the hot ends of the Seebeck effect, and the connecting plate and the two kinds of semiconductors on the refrigerating plate 201 are the refrigerating ends of the Peltier effect.

[0029] Working principle: When the transformer body 12 is working, the control system controls the working of the delivery pump, opens the solenoid valve in the output pipe 21, and the coolant delivery system works. The coolant delivery system delivers the coolant to the storage tank 15 through the pipeline and the liquid injection port 111, and then extracts the coolant in the storage tank 15 to the input pipe 23 through the delivery pump. The coolant flows in the input pipe 23, the intermediate pipe 22, and the output pipe 21 in sequence. Since the diameter of the intermediate pipe 22 is smaller than the diameters of the input pipe 23 and the output pipe 21, under the action of the Venturi effect, a negative pressure will be generated in the intermediate pipe 22, enabling external air to enter the vortex tube 24 through the air inlet 112. The dust passes through multiple groups of filter meshes 242 in the vortex tube 24 in sequence. The multiple groups of filter meshes 242 filter the dust. Moreover, the vortex tube 24 is distributed in a planar thread. The dust and air continuously flow in the vortex tube 24. Since the dust and air have different inertial forces, the dust impacts on the inner wall of the vortex tube 24 and loses its power, and the dust then deposits in the vortex tube 24. The air passes through the vortex tube 24 and is inhaled into the intermediate pipe 22 in sequence. The air is inhaled through the intermediate pipe 22 and impacts with the high-speed coolant to form an aerosol, and then is delivered to the cooling flow channel through the output pipe 21.

[0030] When the aerosol coolant is delivered to the cooling channel through the output pipe 21, the flow meter in the output pipe 21 feeds back the flow data to the control system, and the control system connects the two semiconductors on the multiple groups of refrigeration plates 201 to the circuit. The connecting plates and the two semiconductors on the multiple groups of refrigeration plates 201 are the cooling ends of the Peltier effect, and the heating end of the Peltier effect is not explained. The control system cools the aerosol coolant in the cooling channel through the cooling end to cool the aerosol coolant to the set temperature. The cooled aerosol coolant is sprayed onto the isolation cover 13 from the multiple groups of spray ports 202. The aerosol coolant increases the contact area with the isolation cover 13, thereby improving the cooling effect and allowing the transformer body 12 to dissipate heat quickly.

[0031] When the aerosol coolant is sprayed on the isolation cover 13, the control system connects the connecting plates and two semiconductors on the multiple groups of temperature measuring plates 31 to the circuit according to the data of the flow meter in the output pipe 21. The connecting plates and two semiconductors on the temperature measuring plates 31 are the hot ends of the Seebeck effect, and the cold ends are not explained. The coolant takes away the heat of the isolation cover 13, so that the temperature of the mutual inductor body 12 is reduced. After heat exchange, the coolant is collected and converged downward by the collecting tube 301. The coolant after heat exchange enters the multiple groups of collecting flow channels and contacts the multiple groups of temperature measuring plates 31. At this time, the hot end temperature is higher than the cold end. The Seebeck effect generates current between the hot end and the cold end and transmits it to the control system. The control system detects the size of the generated current, and then obtains the temperature of the coolant after heat exchange in the multiple groups of collecting flow channels.

[0032] After the control system obtains the temperature of the coolant in multiple groups of collecting channels, the control system adjusts the opening degree of the flow control valve in the cooling channel according to the temperature of the coolant in the multiple groups of collecting channels; when the temperature in the collecting channel is higher than the set temperature, the control system increases the opening degree of the flow control valve in the cooling channel directly above the collecting channel, so that the coolant flow in the cooling channel directly above the collecting channel becomes larger, so that the isolation cover 13 and the transformer body 12 are evenly cooled, avoiding the problem of local overheating of the isolation cover 13 and the transformer body 12, so as to achieve targeted cooling of the isolation cover 13 and the transformer body 12 and improve the cooling effect; thereafter, the control system uses the current generated by the Seebeck effect for cooling the refrigeration plate 201 after being processed by voltage transformation and rectification, so as to achieve detection while reducing the energy consumption of the voltage transformer.

[0033] After passing through the multiple collection channels, the coolant returns to the coolant delivery system through the drain port 113 . The coolant delivery system processes the coolant and reuses it.
