Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically a power transformer for use in high-altitude areas. Background Technology

[0002] In high-altitude areas, the air is thin, the air pressure is low, and the temperature difference between day and night is large, which poses a severe challenge to outdoor power transformers. The reduced air density at high altitudes leads to a weakening of convective heat dissipation capacity.

[0003] Under current technology, in order to compensate for the weak convective heat transfer capacity in high-altitude areas, fans are often added to the parts of the transformer that need heat dissipation to enhance the convective heat transfer capacity and improve the heat dissipation effect. However, this method increases the operating cost of the transformer, and because the airflow path is long and tortuous, the improvement effect on heat dissipation is not obvious. At the same time, the operation of the fan also requires frequent maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a power transformer for high-altitude areas, so as to solve the problems of poor heat dissipation and high equipment maintenance requirements in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The power transformer for high-altitude areas includes a base and a refrigerant tank. An iron core is installed on the base, and at least two windings and a shell are installed on the base. The windings are sleeved outside the iron core, and the shell is sleeved around the windings. A heat absorber is provided between the shell and the windings. The refrigerant tank is connected to the heat absorber through a liquid inlet pipe. An exhaust pipe is installed on the heat absorber, and a condensation assembly is connected to the exhaust pipe. The condensation assembly is connected to the refrigerant tank through a liquid return pipe. A detection component for adjusting the working state of the condensation assembly is provided between the condensation assembly and the heat absorber.

[0006] As a preferred technical solution, the condensation assembly includes a return pipe, a collection pipe, a mounting plate, a central pipe, and a condenser pipe;

[0007] The exhaust pipe is equipped with a return pipe, which is connected to the gas collection pipe. The base is equipped with an mounting plate, and a central pipe is mounted on the mounting plate. The central pipe is connected to the gas collection pipe. Several condenser pipes are evenly distributed on both sides of the central pipe, and the condenser pipes are installed at an angle to the central pipe.

[0008] As a preferred technical solution, the condensation assembly also includes a control rod, a plug, a rotating connector, a motor, and an angle sensor;

[0009] A control rod is rotatably installed inside the central tube. Multiple plugs are installed on both sides of the control rod. The distance between adjacent plugs on each side is twice the distance between adjacent condenser tubes on each side. A rotating connector is installed at the bottom of the control rod. An angle sensor is installed on the rotating connector. A motor is installed on the mounting plate. The output shaft of the motor is connected to the rotating connector.

[0010] As a preferred technical solution, the detection component includes a detection box, a temperature sensor, and a probe;

[0011] A detection box is installed at the connection between the gas collecting pipe and the central pipe. A temperature sensor is installed on the detection box, and the probe of the temperature sensor extends into the detection box.

[0012] As a preferred technical solution, the detection assembly further includes a sleeve, a heat-conducting rod, a hot end, a cold end, a lower plate, an upper plate, an instantaneous spring, a locking block, a limiting plate, a sliding groove, an elastic sliding plate, a connecting rod, and a wiping component;

[0013] The mounting box is equipped with a sleeve, inside which is installed a lower plate. An upper plate is slidably installed above the lower plate inside the sleeve, forming a sealed space filled with expanding gas. A heat-conducting rod is installed on the upper plate, penetrating the lower plate. The upper and lower ends of the heat-conducting rod are the hot and cold ends, respectively. Multiple instantaneous springs are evenly installed on the upper plate, connected by locking blocks. A limiting plate is installed on the sleeve, with a sliding groove on it. An elastic sliding plate is slidably installed within the groove. A connecting rod is installed on one side of the cold end of the heat-conducting rod, and a wiping component is installed on the other side of the connecting rod. The wiping component is fitted over the probe.

[0014] As a preferred technical solution, insulation columns are installed on both the cold end and the hot end, an upper insulation ring is installed on the upper part of the sleeve, and a lower insulation ring is installed on the lower part of the sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The heat generated by the transformer is removed through the phase change of the refrigerant. Since the evaporation temperature is basically constant, the temperature of the winding hot spot is kept stable and low, which can improve the cooling effect of the transformer. The steam generated by heat exchange is condensed and then recycled internally, reducing losses and maintenance frequency.

[0019] 2. When using phase change cooling of refrigerant, the characteristic of the boiling point of substances in high-altitude areas is utilized, which effectively reduces the phase change temperature of the refrigerant from liquid to gas, making it easier to remove heat from the windings through phase change, and suitable for use in high-altitude areas.

[0020] 3. This allows the two condenser tubes on the same horizontal plane to work alternately, reducing the risk of thermal fatigue in the condenser tubes, extending their service life, and avoiding frequent maintenance by workers.

[0021] 4. By utilizing the thermal expansion and contraction properties of gases, a heat-conducting rod is driven to wipe the probe, ensuring the accuracy of the detection and the control of the condenser tube's opening status. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-5 As shown, the present invention provides a technical solution for a power transformer for high-altitude areas. The power transformer for high-altitude areas includes a base 1 and a refrigerant tank 5. An iron core 2 is installed on the base 1. At least two windings 3 and a shell 4 are installed on the base 1. The windings 3 are sleeved outside the iron core 2, and the shell 4 is sleeved on the windings 3. A heat absorber 6 is arranged between the shell 4 and the windings 3. The refrigerant tank 5 is connected to the heat absorber 6 through a liquid inlet pipe 7. An exhaust pipe 8 is installed on the heat absorber 6. A condenser assembly 11 is connected to the exhaust pipe 8. The condenser assembly 11 is connected to the refrigerant tank 5 through a liquid return pipe 10. A detection component 12 for adjusting the working state of the condenser assembly 11 is arranged between the condenser assembly 11 and the heat absorber 6.

[0035] When the transformer is in use, the refrigerant in the refrigerant tank 5 is filled into the heat absorber 6 through the liquid delivery pipe 7. The inner wall of the heat absorber 6 is in close contact with the winding 3. When the transformer is working and the winding 3 heats up, the heat is transferred through the heat absorber 6 to raise the temperature of the refrigerant. The refrigerant absorbs heat and evaporates. The gas produced by evaporation enters the condenser assembly 11 through the exhaust pipe 8 and is condensed into liquid. The liquid refrigerant returns to the refrigerant tank 5 through the return pipe 10. The phase change of the refrigerant carries away the heat generated by the transformer. Since the evaporation temperature is basically constant, the hot spot temperature of the winding 3 is kept stable and low, which can improve the cooling effect on the transformer. The steam generated by heat exchange is condensed and then recycled internally, reducing losses and reducing maintenance frequency.

[0036] When using phase change cooling of refrigerant, the characteristic of the boiling point of substances in high-altitude areas is utilized, which effectively reduces the phase change temperature of the refrigerant from liquid to gas, making it easier to remove heat from winding 3 through phase change, and suitable for use in high-altitude areas.

[0037] like Figures 1-6 As shown, the condenser assembly 11 includes a return pipe 1101, a collecting pipe 1102, a mounting plate 1103, a central pipe 1104, and a condenser pipe 1105;

[0038] The exhaust pipe 8 is equipped with a return pipe 1101, which is connected to the gas collection pipe 1102. The base 1 is equipped with a mounting plate 1103, and a central pipe 1104 is installed on the mounting plate 1103. The central pipe 1104 is connected to the gas collection pipe 1102. Several condenser pipes 1105 are evenly distributed on both sides of the central pipe 1104. The condenser pipes 1105 and the central pipe 1104 are installed at an angle.

[0039] After entering the condenser assembly 11, the steam enters the condenser tube 1105 along the central tube 1104 and exchanges heat with the air through the tube wall. The condenser tube 1105 has more sufficient contact with the air, resulting in better heat dissipation. The heat is carried away from the winding 3 and the outer shell 4 by the refrigerant and then exchanged with the air through the condenser tube 1105. This avoids the problem of the air flowing in a tortuous direction in the winding 3, which makes it difficult to improve the heat dissipation effect, and effectively improves the cooling effect of the winding 3.

[0040] Installing the condenser tube 1105 at an angle ensures that the condensed refrigerant can flow out of the condenser tube 1105 in a timely manner for reuse, while avoiding contamination of the condenser tube 1105 and affecting the condensation effect, thus further ensuring the heat dissipation effect on the transformer.

[0041] The condensation assembly 11 also includes a control lever 1106, a plug 1107, a rotating connector 1108, a motor 1109, and an angle sensor 1110;

[0042] A control rod 1106 is rotatably installed inside the central tube 1104. Multiple plugs 1107 are installed on both sides of the control rod 1106. The distance between adjacent plugs 1107 on each side is twice the distance between adjacent condenser tubes 1105 on each side. A rotating connector 1108 is installed at the bottom of the control rod 1106. An angle sensor 1110 is installed on the rotating connector 1108. A motor 1109 is installed on the mounting plate 1103. The output shaft of the motor 1109 is connected to the rotating connector 1108.

[0043] In daily use, the motor 1109 intermittently drives the control lever 1106 to rotate, with each rotation angle being 180 degrees. This allows the two condenser tubes 1105 on the same horizontal plane to work alternately, reducing the risk of thermal fatigue in the condenser tubes 1105, extending their service life, and avoiding frequent maintenance by workers.

[0044] Angle sensor 1110 is linked with motor 1109 for control, which improves the control of condenser tube 1105.

[0045] like Figure 1 and Figures 7-8 As shown, the detection assembly 12 includes a detection box 1201, a temperature sensor 1202, and a probe 1203;

[0046] A detection box 1201 is installed at the connection between the gas collecting pipe 1102 and the central pipe 1104. A temperature sensor 1202 is installed on the detection box 1201, and the probe 1203 of the temperature sensor 1202 extends into the detection box 1201.

[0047] Temperature sensor 1202 is electrically connected to motor 1109. Under normal circumstances, the steam temperature passing through temperature sensor 1202 is near the boiling point of the refrigerant. When the heat generated by the transformer increases and the steam condensation efficiency is insufficient, superheated steam will be generated, and the temperature detected by temperature sensor 1202 will rise. At this time, temperature sensor 1202 will control motor 1109 to drive control lever 1106 to rotate 90 degrees, opening the inlets of all condenser tubes 1105 to work at full load and ensure heat dissipation until the temperature recovers. Then, motor 1109 drives control lever 1106 and plug 1107 to continue to open only one condenser tube 1105 on the same horizontal plane. By regulating the condensation state through the outlet steam temperature, the condensation efficiency can be improved under high load conditions of the transformer, further ensuring the heat dissipation effect of the transformer.

[0048] The detection assembly 12 also includes a sleeve 1204, a heat-conducting rod 1205, a hot end 1206, a cold end 1207, a lower plate 1208, an upper plate 1209, an instantaneous spring 1210, a locking block 1211, a limiting plate 1212, a slide groove 1213, an elastic sliding plate 1214, a connecting rod 1218, and a wiping component 1219;

[0049] The mounting box is equipped with a sleeve 1204, inside which a lower plate 1208 is installed. An upper plate 1209 is slidably installed above the lower plate 1208 within the sleeve 1204, forming a sealed space between the upper plate 1209 and the lower plate 1208. A heat-conducting rod 1205 is installed on the upper plate 1209, penetrating through the lower plate 1208. The upper and lower ends of the heat-conducting rod 1205 are a hot end 1206 and a cold end 1207, respectively. Heat-conducting rods are evenly distributed on the upper plate 1209. There are multiple instantaneous springs 1210, which are connected by a locking block 1211. A limiting plate 1212 is installed on the sleeve 1204. A sliding groove 1213 is provided on the limiting plate 1212. An elastic sliding plate 1214 is slidably installed in the sliding groove 1213. A connecting rod 1218 is installed on one side of the cold end 1207 of the heat-conducting rod 1205. A wiping component 1219 is installed on the other side of the connecting rod 1218. The wiping component 1219 is fitted with the probe 1203.

[0050] The sealed space between the upper plate 1209 and the lower plate 1208 is filled with thermally expanding gas. When hot steam passes through the detection box 1201, the heat-conducting rod 1205 transfers heat to the thermally expanding gas through the hot end 1206, increasing the gas temperature. The expanding gas begins to expand, pushing the upper plate 1209 and the locking block 1211 upwards. Due to the limiting plate 1212, the instantaneous spring 1210 is compressed and stores elastic potential energy. At the same time, the pressure in the sealed space increases until the pushing force of the locking block 1211 on the elastic sliding plate 1214 causes the elastic sliding plate 1214 to slide completely into the slide groove 1213. The elastic potential energy of the instantaneous spring 1210 is released, and the thermally expanding gas in the sealed space expands, causing the upper plate 1209 to drive the heat-conducting rod 1208. 205 moves upward rapidly. At this time, the end of the heat-conducting rod 1205 comes into contact with the air for heat exchange, and begins to reduce the temperature of the thermally expanding gas. The thermally expanding gas contracts, and the pressure in the sealed space decreases. Atmospheric pressure forces the upper plate 1209 to slide downward. The locking block 1211 is locked at the upper end of the limiting block, and the instantaneous spring 1210 extends until the elastic slider slides completely into the slide groove 1213 again. The lower plate 1208 drives the heat-conducting rod 1205 to slide downward rapidly. The up and down sliding of the heat-conducting rod 1205 drives the wiping component 1219 to wipe the probe 1203 through the connecting rod 1218, so as to avoid the formation of a water film at the end of the probe 1203, ensure the accuracy of detection and control of the opening state of the condenser tube 1105, and improve the condensation effect.

[0051] Insulation columns 1215 are installed on both the cold end 1207 and the hot end 1206. An upper insulation ring 1216 is installed on the upper part of the sleeve 1204, and a lower insulation ring 1217 is installed on the lower part of the sleeve 1204.

[0052] When the locking block 1211 is locked below the limiting block, the hot end 1206 is below the lower insulating ring 1217. As the locking block 1211 moves rapidly upward through the limiting plate 1212, the insulating column 1215 of the hot end 1206 contacts the lower insulating ring 1217 to achieve insulation of the hot end 1206, stopping the heat transfer from the hot end 1206 to the thermally expanding gas. When the locking block 1211 is locked above the limiting block, the cold end 1207 is above the upper insulating ring 1216. As the locking block 1211 moves rapidly downward through the limiting plate 1212, the insulating column 1215 of the cold end 1207 contacts the upper insulating ring 1216 to achieve insulation of the hot end 1206, stopping the heat transfer from the cold end 1207 to the thermally expanding gas. This achieves separate control of the heating and cooling of the thermally expanding gas, preventing the state of the thermally expanding gas from becoming stable and causing the heat-conducting rod 1205 to be unable to slide.

[0053] A pump 13 is installed on the refrigerant tank 5, and a flow damper 9 is installed on the upper end of the infusion pipe 7. The flow damper 9 is connected to the output end of the pump 13.

[0054] The flow buffer 9 is equipped with a water level detector, which controls the operation of the pump 13 to ensure that there is always refrigerant in the flow buffer 9. When the refrigerant in the heat absorber 6 evaporates and the remaining amount decreases, the flow buffer 9 will replenish the heat absorber 6 with refrigerant to ensure the heat transfer effect of the transformer.

[0055] The absorber 6 has multiple exhaust pipes 8 installed around its perimeter, and the exhaust pipe 8 on one absorber 6 is connected to the return pipe 1101.

[0056] The multiple exhaust pipes 8 prevent the generation of overheated gas due to untimely steam discharge, thus reducing the heat dissipation effect. The multiple exhaust pipes 8 further improve the heat dissipation effect.

[0057] Working principle of the invention:

[0058] When the transformer is in use, the refrigerant in the refrigerant tank 5 is filled into the heat absorber 6 through the liquid delivery pipe 7. The inner wall of the heat absorber 6 is in close contact with the winding 3. When the transformer is working and the winding 3 heats up, the heat passes through the heat absorber 6, which raises the temperature of the refrigerant. The refrigerant absorbs heat and evaporates. The gas produced by evaporation enters the condenser assembly 11 through the exhaust pipe 8 and is condensed into liquid. The liquid refrigerant returns to the refrigerant tank 5 through the return pipe 10. This technical solution removes the heat generated by the transformer through the phase change of the refrigerant. Since the evaporation temperature is basically constant, the hot spot temperature of the winding 3 is stable and low, which can improve the cooling effect on the transformer. The steam generated by heat exchange is condensed and then recirculated for use, reducing losses and reducing maintenance frequency.

[0059] When using phase change cooling of refrigerant, the characteristic of the boiling point of substances in high-altitude areas is utilized, which effectively reduces the phase change temperature of the refrigerant from liquid to gas, making it easier to remove heat from winding 3 through phase change, and suitable for use in high-altitude areas.

[0060] After entering the condenser assembly 11, the steam enters the condenser tube 1105 along the central tube 1104 and exchanges heat with the air through the tube wall. The condenser tube 1105 has more sufficient contact with the air, resulting in better heat dissipation. The heat is carried away from the winding 3 and the outer shell 4 by the refrigerant, and then exchanged with the air through the condenser tube 1105. This avoids the problem of the air flowing in a tortuous direction in the winding 3, which makes it difficult to improve the heat dissipation effect, and effectively improves the cooling effect of the winding 3.

[0061] Installing the condenser tube 1105 at an angle ensures that the condensed refrigerant can flow out of the condenser tube 1105 in a timely manner for reuse, while avoiding contamination of the condenser tube 1105 and affecting the condensation effect, thus further ensuring the heat dissipation effect on the transformer.

[0062] In daily use, the motor 1109 intermittently drives the control lever 1106 to rotate, with each rotation angle being 180 degrees. This allows the two condenser tubes 1105 on the same horizontal plane to work alternately, reducing the risk of thermal fatigue in the condenser tubes 1105, extending their service life, and avoiding frequent maintenance by workers.

[0063] Temperature sensor 1202 is electrically connected to motor 1109. Under normal circumstances, the steam temperature passing through temperature sensor 1202 is near the boiling point of the refrigerant. When the heat generated by the transformer increases and the steam condensation efficiency is insufficient, superheated steam will be generated, and the temperature detected by temperature sensor 1202 will rise. At this time, temperature sensor 1202 will control motor 1109 to drive control lever 1106 to rotate 90 degrees, opening the inlets of all condenser tubes 1105 to work at full load and ensure heat dissipation until the temperature recovers. Then, motor 1109 drives control lever 1106 and plug 1107 to continue to open only one condenser tube 1105 on the same horizontal plane. By regulating the condensation state through the outlet steam temperature, the condensation efficiency of the transformer can be improved under high load, further ensuring the heat dissipation effect of the transformer.

[0064] The sealed space between the upper plate 1209 and the lower plate 1208 is filled with thermally expanding gas. When hot steam passes through the detection box 1201, the heat-conducting rod 1205 transfers heat to the thermally expanding gas through the hot end 1206, increasing the gas temperature. The expanding gas begins to expand, pushing the upper plate 1209 and the locking block 1211 upwards. Due to the limiting plate 1212, the instantaneous spring 1210 is compressed and stores elastic potential energy. At the same time, the pressure in the sealed space increases until the pushing force of the locking block 1211 on the elastic sliding plate 1214 causes the elastic sliding plate 1214 to slide completely into the slide groove 1213. The elastic potential energy of the instantaneous spring 1210 is released, and the thermally expanding gas in the sealed space expands, causing the upper plate 1209 to drive the heat-conducting rod 1208. 205 moves upward rapidly. At this time, the end of the heat-conducting rod 1205 comes into contact with the air for heat exchange, and begins to reduce the temperature of the thermally expanding gas. The thermally expanding gas contracts, and the pressure in the sealed space decreases. Atmospheric pressure forces the upper plate 1209 to slide downward. The locking block 1211 is locked at the upper end of the limiting block, and the instantaneous spring 1210 extends until the elastic slider slides completely into the slide groove 1213 again. The lower plate 1208 drives the heat-conducting rod 1205 to slide downward rapidly. The up and down sliding of the heat-conducting rod 1205 drives the wiping component 1219 to wipe the probe 1203 through the connecting rod 1218, so as to avoid the formation of a water film at the end of the probe 1203, ensure the accuracy of detection and control of the opening state of the condenser tube 1105, and improve the condensation effect.
