Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical equipment, and in particular to SF6 gas insulated ring main unit. Background Art
[0002] SF6 gas insulated ring main unit is widely used in power systems, especially in urban power grid transformation and distribution network construction. In actual application, the electrical components inside the ring main unit will generate a lot of heat during long-term operation, which will cause the internal temperature of the equipment to rise. In addition, the gas insulated ring main unit is sealed, so the internal heat is more difficult to dissipate, thus affecting the normal working performance and service life of the equipment.
[0003] At present, in order to reduce the temperature inside the ring network cabinet, air cooling or water cooling is usually used. Air cooling achieves the purpose of cooling by installing a fan to speed up the air flow speed on the surface of the ring network cabinet, while water cooling achieves the cooling effect by installing a water cooling pipe outside the ring network cabinet and taking away the heat through circulating water.
[0004] Regarding the above-mentioned related technologies, it is difficult for a single air cooling or water cooling method to achieve an ideal cooling effect. More importantly, the traditional method lacks a stable temperature monitoring and control mechanism. When the temperature of the ring network cabinet rises rapidly, it cannot respond quickly and effectively, causing the equipment to continue to run for too long in a high temperature environment, aggravating the loss of the equipment. After the temperature drops, the cooling device cannot be quickly turned off, resulting in continuous waste of cooling resources, resulting in ineffective consumption of energy and failure to achieve efficient use of resources. Summary of the invention
[0005] In order to improve the cooling effect of the gas insulated ring main unit while saving resources and improving the cooling efficiency, the present application provides an SF6 gas insulated ring main unit.
[0006] The SF6 gas insulated ring main unit provided in this application adopts the following technical solution: SF6 gas insulated ring main unit, including: A cooling box, wherein a door is hingedly connected to one side wall of the cooling box; A ring main unit, wherein the ring main unit is arranged in the inner cavity of the cooling box; A water cooling component, the water cooling component is installed on the cooling box, and the water cooling component is used to reduce the temperature of the ring network cabinet; An air cooling component, the air cooling component is installed in the cooling box, the air cooling component is connected to the water cooling component, and the air cooling component is used to reduce the temperature of the ring network cabinet; A moving part, the moving part is installed in the cooling box, the moving part is connected to the air cooling component, and the moving part is used to move the air cooling component; A regulating component, the regulating component includes a control component and an adjusting component, the control component and the adjusting component are both installed in the cooling box, the control component is connected to the ring network cabinet, the adjusting component is connected to the water cooling component, and the regulating component is used to regulate the operating state of the water cooling component.
[0007] By adopting the above technical solution, the water cooling component and the air cooling component are combined to form a composite cooling system. The water cooling has a high heat capacity and a stable cooling effect, and can continuously absorb a large amount of heat emitted by the ring network cabinet. The air cooling component can enhance the flow of air and promote the rapid dissipation of heat. The two work together to effectively reduce the temperature of the ring network cabinet. At the same time, the moving parts drive the air cooling component to move in the cooling box during the water cooling process, further enhancing the cooling effect. The control component can monitor and control the operating status of the water cooling component in real time, ensuring that the cooling measures are quickly started when the temperature rises and stopped in time after the temperature drops, avoiding ineffective consumption of energy, achieving efficient utilization of resources, and reducing the operating cost of the ring network cabinet.
[0008] Optionally, the control element includes: An air bag, wherein the air bag is fixedly installed in the ring main unit and an air outlet is provided on the air bag; A telescopic rod, wherein the telescopic rod is rotatably mounted outside the ring main unit, a rodless cavity of the telescopic rod is communicated with the air outlet, and a movable end of the telescopic rod is connected with the adjusting member; A return spring, the return spring being installed in the rod cavity of the telescopic rod and being wound around the telescopic rod; A switch is fixedly installed in the rodless cavity of the telescopic rod, the switch is connected to the water cooling component, and the switch is used to control the operating state of the water cooling component.
[0009] By adopting the above technical solution, the control component utilizes the thermal expansion and contraction characteristics of gas to sense the temperature changes inside the ring network cabinet, and drives the movement of the telescopic rod through the thermal expansion and contraction of the airbag. As the temperature inside the ring network cabinet increases, the volume of the airbag increases, pushing the telescopic rod outward, thereby triggering the switch and driving the adjustment component at the same time to start the water cooling component to achieve timely cooling.
[0010] When the temperature drops to a safe range, the volume of the airbag decreases, the telescopic rod retracts under the action of the reset spring, the switch is turned off and the state of the adjustment part is controlled, so that the water cooling component stops running, reducing unnecessary energy consumption. No complex electronic sensors and control systems are required, which improves the stability and reliability of the system and reduces the risk of control failure caused by electronic component failure. The control component not only ensures the safe and stable operation of the ring network cabinet, but also minimizes the operating cost and resource consumption.
[0011] Optionally, the adjusting member includes: A blocking plate, the blocking plate is mounted on the water cooling assembly, the blocking plate is provided with a mounting groove, and the blocking plate is provided with a first flow opening; A rotating disk, the rotating disk is rotatably mounted in the mounting groove, and a second flow port is opened on the rotating disk; A connecting rod, two ends of which are respectively hinged to the movable end of the telescopic rod and the center of the rotating disk.
[0012] By adopting the above technical solution, when the temperature change in the ring network cabinet causes the volume of the airbag to change, the telescopic rod will be extended and retracted accordingly, driving the rotating disk to rotate. By rotating the rotating disk in the sealing disk installation groove, the relative position change of the second flow port and the first flow port is used to achieve dynamic adjustment of the flow rate of the coolant, thereby achieving adjustment of the cooling speed of the water cooling component. This design not only improves the response speed of the cooling process, but also can flexibly adjust the cooling intensity according to the actual temperature change of the ring network cabinet, avoiding the hysteresis and resource waste problems of traditional cooling methods, and achieving efficient use of resources.

[0014] By adopting the above technical solution, the coolant in the water tank is driven by the circulating pump to flow through the condenser. The circulating pump can be started or stopped as needed through electrical connection with the switch. The condenser coil is arranged on the outer wall of the ring network cabinet, which can fully absorb the heat generated by the ring network cabinet, thereby realizing effective water cooling. The condenser ensures that the coolant is always in a low temperature state during the circulation process, which can effectively improve the heat dissipation efficiency of the ring network cabinet.

[0016] By adopting the above technical solution, the air cooling component and the water cooling component are tightly combined, and the first wheel shell is connected to the condenser, so that the coolant in the condenser can drive the first impeller to rotate. The first impeller enables the liquid flow in the condenser to be effectively converted into mechanical energy, thereby driving the rotating rod and the fan blades to move, forcing air flow, further enhancing the heat dissipation effect of the ring network cabinet, and effectively reducing the temperature inside the ring network cabinet.

[0018] By adopting the above technical solution, the second wheel shell can make the coolant in the condenser tube drive the second impeller to rotate, and then drive the reciprocating screw to rotate, so that the slider makes reciprocating linear motion along the reciprocating screw, driving the air-cooled component to move, thereby increasing the coverage range of the air-cooled component, achieving effective heat dissipation of different areas of the ring network cabinet, enhancing the heat dissipation effect, and realizing the synergistic effect of air cooling and water cooling, further improving the cooling efficiency and resource utilization.
[0019] Optionally, the airbag is filled with a gas with a large thermal expansion coefficient.

[0023] Optionally, the condenser is evenly wound in an S shape on the outer wall of the ring network cabinet.
[0024] By adopting the above technical solution, the condenser is evenly wound in an S shape on the outer wall of the ring network cabinet, which can significantly increase the contact area between the condenser and the ring network cabinet, thereby improving the cooling efficiency, ensuring that the internal temperature of the ring network cabinet is effectively controlled, and extending the service life of the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0031] The following is combined with Figure 1-6 This application is described in further detail.
[0032] The embodiment of the present application discloses an SF6 gas insulated ring main unit.
[0033] Reference Figure 1, the SF6 gas insulated ring network cabinet comprises a cooling box 1, a ring network cabinet 2, a water cooling component 3, an air cooling component 4, a moving part 5, and a regulating component 6. A box door 11 is hinged on one side wall of the cooling box 1, the ring network cabinet 2 is arranged in the inner cavity of the cooling box 1, the water cooling component 3 is installed on the cooling box 1, and the water cooling component 3 is used to reduce the temperature of the ring network cabinet 2; the air cooling component 4 is installed in the cooling box 1, the air cooling component 4 is connected to the water cooling component 3, and the air cooling component 4 is used to reduce the temperature of the ring network cabinet 2; the moving part 5 is installed in the cooling box 1, the moving part 5 is connected to the air cooling component 4, and the moving part 5 is used to move the air cooling component 4, and the regulating component 6 comprises a control part 61 and an adjusting part 62, both of which are installed in the cooling box 1, the control part 61 is connected to the ring network cabinet 2, the adjusting part 62 is connected to the water cooling component 3, and the regulating component 6 is used to regulate the operating state of the water cooling component 3.
[0034] When the ring main unit starts running, the electrical components inside it will gradually generate heat. At this time, the control component 61 installed in the ring main unit 2 monitors the temperature inside the ring main unit 2 by sensing temperature changes. When the temperature reaches outside the normal range, the control component 61 and the adjustment component 62 jointly drive the water cooling component 3 to start working, and perform heat exchange with the surface of the ring main unit 2, thereby reducing the temperature inside the ring main unit 2.
[0035] When the water cooling component 3 is working, it drives the air cooling component 4 to start working, and the water cooling component 3 drives the moving part 5 to work at the same time, and the moving part 5 makes the air cooling component 4 move in the cooling box 1 to speed up the air flow in the cooling box 1. The two work together to reduce the temperature in the ring network cabinet 2, so that the temperature in the ring network cabinet 2 is maintained within a reasonable operating temperature range.
[0036] Reference Figure 2 and Figure 5 The water cooling assembly 3 includes a water tank 31, a circulation pump 32, a condenser 33 and a condenser 34. The water tank 31 is arranged on the top of the ring network cabinet 2, and a water inlet and a water outlet are provided on the water tank 31. The circulation pump 32 is fixedly installed in the water tank 31. One end of the condenser 33 passes through the water outlet and is connected to the circulation pump 32. The condenser 33 is filled with cooling liquid. The condenser 33 is evenly arranged on the outer wall of the ring network cabinet 2 in an S shape. One end of the condenser 33 away from the circulation pump 32 is connected to the water inlet. The condenser 34 is fixedly installed on the cooling box 1. The condenser 33 is connected and arranged on the condenser 34. The condenser 34 is used to cool the cooling liquid in the condenser 33. The use of the condenser 34 in this embodiment is a prior art and will not be described in detail here.
[0037] As the ring main unit continues to operate, the heat generated by its internal electrical components gradually increases. As the temperature of the ring main unit 2 continues to rise, the circulation pump 32 is started under the action of the control component 61, so that the coolant flows in the condenser tube 33 and exchanges heat with the outer wall of the ring main unit 2. Since the condenser tube 33 is evenly coiled in an S shape, the contact area between it and the outer wall of the ring main unit 2 is large, and it can more fully absorb the heat emitted by the ring main unit 2. After the coolant absorbs the heat, the temperature rises, and the coolant enters the condenser 34 with the absorbed heat. The cooled coolant flows back to the water tank 31 through the water inlet, and then is drawn by the circulation pump 32 again to enter the next round of cooling cycle, continuously cooling the ring main unit 2 to cope with the continuous increase in the temperature of the ring main unit 2.
[0038] Reference Figure 2 and Figure 3 The control part 61 includes an airbag 611, a telescopic rod 612, a reset spring 613 and a switch 614. The airbag 611 is fixedly mounted on the inner wall of the ring network cabinet 2. The airbag 611 is filled with a gas with a large thermal expansion coefficient and stable chemical properties at high temperatures. This embodiment does not specifically limit the gas to be filled. An air outlet is provided on the airbag 611. The telescopic rod 612 is rotatably mounted on the outer wall of the ring network cabinet 2. A small hole is provided at the corresponding part of the side wall of the ring network cabinet 2. The rodless cavity of the telescopic rod 612 is connected to the air outlet through the small hole. The small hole of the ring network cabinet 2 has a sealing measure. The specific sealing method is not specifically limited in this embodiment, so that the insulating gas in the ring network cabinet 2 cannot leak out through the small hole.
[0039] The movable end of the telescopic rod 612 is connected to the adjusting member 62, the reset spring 613 is installed in the rod cavity of the telescopic rod 612, the reset spring 613 is wound around the movable rod of the telescopic rod 612, the switch 614 is embedded in the rodless cavity of the telescopic rod 612, the switch 614 is electrically connected to the circulating pump 32, and the switch 614 is used to control the operating state of the circulating pump 32.
[0040] Reference Figure 4 The adjusting member 62 includes a blocking plate 621, a rotating plate 622 and a connecting rod 623. The blocking plate 621 is fixedly mounted on the side wall of the water tank 31 and is a side provided with the telescopic rod 612. The blocking plate 621 is a circular plate body. A first flow port 6211 is provided on the blocking plate 621, so that the first flow port 6211 is connected with the water outlet. One end of the condenser pipe 33 away from the circulation pump 32 is fixedly connected to the first flow port 6211 of the blocking plate 621. A circular mounting groove is provided in the blocking plate 621. The rotating plate 622 is rotatably mounted in the mounting groove. A second flow port 6221 is provided on the rotating plate 622. By rotating the rotating plate 622, the first flow port 6211 can be connected with the second flow port 6221. The two ends of the connecting rod 623 are respectively hinged to the movable end of the telescopic rod 612 and the center of the rotating plate 622.
[0041] After the ring main unit 2 is started and begins to operate normally, the electrical components in the ring main unit 2 are in normal working condition, the heat generated has not caused a significant change in the internal temperature of the ring main unit 2, and the gas state in the airbag 611 is relatively stable.
[0042] As the running time of the ring main unit 2 increases, the electrical components inside the ring main unit 2 continue to generate heat. When the temperature inside the ring main unit 2 gradually increases, the gas in the airbag 611 expands due to the heat. Due to the thermal expansion and contraction characteristics of the gas, the expanded gas in the airbag 611 will pass through the air outlet and enter the rodless cavity of the telescopic rod 612. The gas pressure entering the rodless cavity of the telescopic rod 612 will push the movable end of the telescopic rod 612 to extend. At this time, the return spring 613 in the rod cavity is compressed. During the movement of the rodless cavity, the switch 614 in the rodless cavity is turned on to start the water pump. At the same time, the extension action of the movable end of the telescopic rod 612 is transmitted to the rotating disk 622 through the connecting rod 623, so that the rotating disk 622 starts to rotate in the mounting groove of the blocking disk 621.
[0043] As the rotating disk 622 rotates, the relative positions of the second flow port 6221 on the rotating disk 622 and the first flow port 6211 on the sealing disk 621 change. When the temperature rises, the overlapping area of the second flow port 6221 and the first flow port 6211 gradually increases, thereby increasing the flow rate of the coolant in the condenser tube 33 and accelerating the heat exchange speed between the ring network cabinet 2 and the condensate.
[0044] When the temperature of the ring network cabinet 2 gradually decreases, the gas in the airbag 611 begins to shrink. At this time, the compressed return spring 613 will release its elastic potential energy, pushing the movable end of the telescopic rod 612 to retract, so that the telescopic rod 612 begins to return to its initial state. The telescopic rod 612 drives the rotating disk 622 to rotate in the opposite direction through the connecting rod 623. The overlapping area of the second flow port 6221 on the rotating disk 622 and the first flow port 6211 on the blocking disk 621 gradually decreases, thereby reducing the flow rate of the coolant in the condenser 33. When the first flow port 6211 and the second flow port 6221 are completely misaligned, the telescopic rod 612 retracts and the switch 614 is closed at the same time, the circulating pump 32 stops working, and the water cooling stops, so as to avoid the water cooling component 3 still running at a higher flow rate when the temperature of the ring network cabinet 2 has dropped, thereby wasting energy.
[0045] Reference Figure 2 and Figure 6The air cooling assembly 4 includes a first wheel shell 41, a first impeller 42, a rotating rod 43 and a fan blade 44. The first wheel shell 41 is arranged in the cooling box 1. The first wheel shell 41 is cylindrical and has a cavity inside. The first wheel shell 41 is connected with the condenser 33. The connection point of the condenser 33 and the first wheel shell 41 deviates from the center of the first wheel shell 41. The condenser 33 at the connection point with the first wheel shell 41 is made of a bellows. The first impeller 42 is rotatably installed in the first wheel shell 41. The outer edge of the first impeller 42 abuts against the inner wall of the first wheel shell 41, so that when the coolant flows, the first impeller 42 rotates in the first wheel shell 41. The rotating rod 43 is arranged horizontally, and one end of the rotating rod 43 is fixedly installed at the center of the first impeller 42. There are four fan blades 44, and the four fan blades 44 are fixedly installed at one end of the rotating rod 43 away from the first impeller 42. The four fan blades 44 are evenly arranged around the axis of the rotating rod 43.
[0046] During the operation of the ring main unit 2, when the water cooling component 3 is in operation, the coolant in the condenser 33 circulates and flows into the first wheel shell 41. The flow of the coolant impacts the first impeller 42. Since the outer edge of the first impeller 42 abuts against the inner wall of the first wheel shell 41, the first impeller 42 starts to rotate in the first wheel shell 41. The first impeller 42 drives the rotating rod 43 to rotate together, and the four blades 44 at the other end of the rotating rod 43 also start to rotate.
[0047] When the temperature inside the ring network cabinet 2 increases, the coolant flow rate increases, which increases the impact force on the first impeller 42 and increases the rotation speed. The rotating rod 43 drives the fan blades 44 to rotate at a faster speed, generating a stronger airflow. When the temperature inside the ring network cabinet 2 decreases, the water cooling component 3 will adjust the operating state accordingly, the coolant flow rate decreases, and the impact force of the coolant flowing into the first wheel shell 41 on the first impeller 42 is reduced. The rotation speed of the first impeller 42 decreases accordingly, and the rotation speed of the fan blades 44 driven by the rotating rod 43 also slows down. While meeting the basic heat dissipation requirements of the ring network cabinet 2, unnecessary energy consumption is avoided, thereby achieving the purpose of energy saving.
[0048] Reference Figure 2 and Figure 6The movable member 5 includes a second wheel shell 51, a second impeller 52, a reciprocating screw 53 and a slider 54. The second wheel shell 51 is fixedly mounted on the top of the inner wall of the cooling box 1, the second wheel shell 51 is connected with the condenser 33, and the connection between the condenser 33 and the second wheel shell 51 deviates from the center of the second wheel shell 51. The second impeller 52 is rotatably mounted in the second wheel shell 51, and the outer edge of the second impeller 52 abuts against the inner wall of the second wheel shell 51, so that when the coolant flows, the second impeller 52 rotates in the second wheel shell 51. The second impeller 52 has the same structure as the first impeller 42, and the reciprocating screw 53 is rotatably mounted in the cooling box 1. The reciprocating screw 53 is vertically arranged, one end of the reciprocating screw 53 is coaxial and fixedly mounted on the second impeller 52, and the other end of the impeller is rotatably mounted on the cooling box 1. The slider 54 is threadedly connected to the reciprocating screw 53, and the first wheel shell 41 is fixedly mounted on the slider 54, and one side of the slider 54 abuts against the inner wall of the cooling box 1.
[0049] Similar to the air-cooling component 4, during the operation of the ring network cabinet 2, when the water-cooling component 3 is in operation, the coolant in the condenser 33 circulates and flows into the second wheel shell 51. The coolant flow impacts the second impeller 52, causing it to rotate in the second wheel shell 51. The rotation of the second impeller 52 drives the reciprocating screw 53 to rotate, causing the slider 54 to move up and down, thereby driving the air-cooling component 4 to move up and down, so that the air-cooling component 4 can cool down evenly.
[0050] As the temperature in the ring network cabinet 2 increases, under the action of the regulating component 6, the flow rate and flow velocity of the coolant in the condenser 33 increase, and the impact force of the coolant flowing into the second wheel shell 51 on the second impeller 52 increases. The second impeller 52 drives the reciprocating screw 53 to rotate faster, thereby driving the air cooling component 4 to move faster, and the air flow in the cooling box 1 is accelerated, thereby improving the heat dissipation efficiency and effectively avoiding local overheating from causing damage to the equipment.
[0051] The implementation principle of the SF6 gas insulated ring main unit of the embodiment of the present application is as follows: during the operation of the ring main unit 2, the electrical components generate heat, causing the temperature inside the box to rise. The temperature change is sensed by the control component 61. When the temperature rises, the gas in the airbag 611 expands, and the pressure in the rodless cavity of the telescopic rod 612 increases through the air outlet, pushing the movable end of the telescopic rod 612 to extend, and at the same time the reset spring 613 is compressed, and the movable end of the telescopic rod 612 drives the rotating disk 622 in the adjusting component 62 to rotate through the connecting rod 623, so that the overlapping area of the first flow port 6211 of the blocking disk 621 and the second flow port 6221 of the rotating disk 622 changes, thereby controlling the coolant flow of the water cooling component 3. When the pressure in the rodless cavity of the telescopic rod 612 reaches the triggering threshold of the switch 614, the switch 614 controls the circulating pump 32 to strengthen the water cooling circulation.
[0052] In the water-cooling component 3, the circulating pump 32 works in the water tank 31, driving the coolant from the water outlet through the condenser 33 to absorb the heat of the ring network cabinet 2, dissipating the heat through the condenser 34, and then returning to the water tank 31 from the water inlet. The condenser 33 is connected to the first wheel shell 41 of the air-cooling component 4. The coolant flows and impacts the first impeller 42 in the first wheel shell 41, driving the rotating rod 43 and the fan blades 44 to rotate, thereby producing an air-cooling effect.
[0053] The second wheel housing 51 of the moving part 5 is also connected to the condenser 33. The coolant drives the second impeller 52 to rotate, driving the reciprocating screw 53 to move the slider 54, and then driving the air cooling component 4 to move. When the temperature rises, the air cooling component 4 moves faster to strengthen the heat dissipation; when the temperature drops, the components are adjusted to reduce the cooling intensity, so as to achieve effective resource utilization and precise temperature control.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
