[0001] The present invention belongs to the technical field of electrical equipment and relates to a gas-insulated switchgear with oil-sealed arc extinguishing form. Background Art

[0002] A gas-insulated switchgear is a high-voltage switchgear that uses compressed gas for insulation. It protects internal components through a sealed design and is suitable for power control in relatively complex environments. Its core features include a modular structure, a high protection level, and a compact volume, enabling it to withstand harsh conditions such as high temperature, sand, and extreme cold.

[0003] The main feature of a gas-insulated switchgear is that electrical equipment such as circuit breakers, disconnectors, and load switches are sealed in a gas tank filled with inert gas. Since the core electrical equipment is sealed, it can reduce the impact of the external environment on the electrical equipment, improve the working stability and service life, and reduce the maintenance cost.

[0028] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Embodiment 1

[0030] As Figures 1 to 5 shown, it includes an air-filled cabinet body 101. Inside the air-filled cabinet body 101, an arc extinguishing tube body 1 is fixedly connected. The inside of the arc extinguishing tube body 1 can be filled with a sufficient amount of oil medium. At the end of the arc extinguishing tube body 1, a sealing cover plate 2 is fixedly connected. In the middle of the sealing cover plate 2, a sliding rod 3 is slidably connected. At the end of the sliding rod 3, a first disc 4 is fixedly connected. Inside the arc extinguishing tube body 1, multiple groups of arc extinguishing gaskets 5 are fixedly connected, which can eliminate the electric arc generated in the middle of the first disc 4. In the middle of the inside of the arc extinguishing tube body 1, a support rod 6 is fixedly connected. At the end of the support rod 6, a second disc 7 is fixedly connected. The first disc 4 and the second disc 7 are separated from each other to perform a power-off process. A rotating groove 8 is formed in the middle of the sliding rod 3, and a cleaning assembly is arranged in the middle of the rotating groove 8, which can clean the impurities accumulated in the middle of the arc extinguishing gaskets 5. A cleaning assembly is arranged at the bottom inside the arc extinguishing tube body 1, which can clean the impurities generated at the bottom of the arc extinguishing tube body 1.

[0031] When performing the power-off process, the sufficient amount of oil medium filled inside the arc extinguishing tube body 1 can be used to eliminate the electric arc. After long-term use, more impurities will be generated in the oil medium in the middle of the arc extinguishing tube body 1. At this time, the cleaning assembly can be used to clean the impurities adhered to the middle of the arc extinguishing gaskets 5, thereby reducing the situation that the accumulation of impurities in the middle of the arc extinguishing gaskets 5 affects the elimination of the electric arc. The cleaning assembly at the bottom inside the arc extinguishing tube body 1 can clean the impurities at the bottom of the arc extinguishing tube body 1 to the outside, thereby reducing the situation that the elimination of the electric arc is affected due to a large amount of impurities contained in the oil medium when using the oil medium to eliminate the electric arc.

[0032] The cleaning assembly includes a collar 9, a connecting rod 10, a cleaning brush 11, a sliding groove 12, and a rotating rod 13. A collar 9 is rotatably connected in the middle of the rotating groove 8, and the collar 9 can rotate in the middle of the rotating groove 8. Multiple groups of connecting rods 10 are fixedly connected in the middle of the collar 9. At the end of the connecting rod 10, a cleaning brush 11 is fixedly connected. The connecting rod 10 can support the cleaning brush 11. The cleaning brush 11 is slidably connected with the arc extinguishing gaskets 5. A sliding groove 12 is formed in the middle of the sliding rod 3, and a transmission assembly is arranged inside the sliding groove 12.

[0033] When it is necessary to clean the impurities stuck in the middle of the arc extinguishing gasket 5, the transmission component can transfer kinetic energy to the rotating groove 8 through the slide groove 12, and then the ring 9 can be rotated in the middle of the rotating groove 8, and then the cleaning brush 11 can be supported by the connecting rod 10 to slide in the middle of the arc extinguishing gasket 5, and then the impurities stuck in the middle of the arc extinguishing gasket 5 can be cleaned by the cleaning brush 11, which can reduce the situation where impurities stuck in the middle of the arc extinguishing gasket 5 affect the elimination of the arc.

[0034] The transmission assembly includes a rotating rod 13, a transmission plate 14, and a twisting knob 15. The rotating rod 13 is rotatably connected inside the slide rod 3. Multiple groups of transmission plates 14 are fixedly connected to the end of the rotating rod 13. The transmission plates 14 are slidably connected to the slide grooves 12. The ends of the transmission plates 14 are fixedly connected to the inner wall of the sleeve 9. The end of the rotating rod 13 away from the transmission plates 14 is fixedly connected to the twisting knob 15. The transmission plates 14 can be rotated by turning the twisting knob 15. The twisting knob 15 is slidably connected to the slide rod 3.

[0035] When it is necessary to use the cleaning brush 11 to clean the impurities stuck in the middle of the arc extinguishing gasket 5, the rotating rod 13 can be rotated by turning the twist 15, and then the ring 9 can be rotated in the middle of the rotating groove 8 through the fixed connection between the transmission plate 14 and the ring 9, so that the cleaning brush 11 can be driven by the connecting rod 10 to slide in the middle of the arc extinguishing gasket 5, and then when there is no need to remove the oil medium inside the arc extinguishing tube body 1, the impurities stuck in the middle of the arc extinguishing gasket 5 can be cleaned, which can reduce the situation where the oil medium contains a large amount of impurities and affects the elimination of the arc.

[0036] The cleaning assembly includes a sweeping rod 22, a cleaning plate 23, a guide hole 24, and a rubber plug 25. The sweeping rod 22 is fixedly connected to the middle part of the support rod 6. The sweeping rod 22 can be driven to rotate inside the arc-extinguishing tube body 1 by rotating the support rod 6. The cleaning plate 23 is fixedly connected to the end of the sweeping rod 22. The cleaning plate 23 is slidably connected to the bottom of the arc-extinguishing tube body 1. The cleaning plate 23 can clean impurities at the bottom of the arc-extinguishing tube body 1. A guide hole 24 is opened at the bottom of the arc-extinguishing tube body 1. Impurities at the bottom of the arc-extinguishing tube body 1 can be cleaned to the outside through the guide hole 24. A rubber plug 25 is slidably connected inside the guide hole 24.

[0037] When the oil medium inside the arc-extinguishing tube body 1 contains a large amount of impurities, the rubber plug 25 can be taken out from the middle of the guide hole 24, and then the support rod 6 can be rotated, so that the cleaning plate 23 at the end of the sweeping rod 22 can clean the impurities accumulated at the bottom of the arc-extinguishing tube body 1, and then the impurities can be cleaned out of the interior of the arc-extinguishing tube body 1 through the guide hole 24, and then when it is necessary to replace the oil medium inside the arc-extinguishing tube body 1, the residual impurities inside the arc-extinguishing tube body 1 can be reduced, and the impact on the arc elimination can be reduced.

[0038] Example 2

[0039] As Figures 3 to 6 shown, a groove 16 is provided in the middle of the first disc 4. A snap ring 17 is fixedly connected to the middle of the groove 16. A spring 19 is fixedly connected inside the snap ring 17. One end of the spring 19 is fixedly connected to a pressing block 20. The pressing block 20 is slidably connected to the snap ring 17. One end of the pressing block 20 is fixedly connected to an elastic piece 21. The elastic piece 21 is slidably connected to the second disc 7.

[0040] When the end of the first disc 4 is in contact with the end of the second disc 7, the elastic piece 21 can be made to contact the end of the second disc 7 first. Then, in the process of the first disc 4 and the second disc 7 approaching each other, the pressing block 20 can squeeze the spring 19, and then the pressing block 20 can slowly enter the inside of the snap ring 17. In the process of the elastic piece 21 contacting the second disc 7, the oil medium between their contact surfaces will be gradually squeezed outwards, so that after the first disc 4 and the second disc 7 are in contact, the situation of poor contact due to a large amount of oil medium in the middle can be reduced.

[0041] A conical pad 26 is fixedly connected to the bottom of the arc extinguishing tube body 1. The oil medium inside the arc extinguishing tube body 1 can slide towards the bottom of the arc extinguishing tube body 1 through the conical pad 26. A plurality of guide grooves 27 are provided in the middle of the conical pad 26. The guide grooves 27 can guide the oil medium in the middle of the conical pad 26. The side of the conical pad 26 is slidably connected to the cleaning plate 23. At this time, the cleaning plate 23 can push and clean the oil medium sliding down from the middle of the conical pad 26.

[0042] When it is necessary to replace the oil medium inside the arc extinguishing tube body 1, through the action of the conical pad 26, the situation that the oil medium inside the arc extinguishing tube body 1 stays in the middle of the arc extinguishing tube body 1 can be reduced. Through the action of the guide grooves 27, the oil medium can flow towards the bottom of the arc extinguishing tube body 1 more quickly. Then, through the rotating action of the cleaning plate 23, the oil medium can be discharged to the outside through the guide holes 24. Therefore, when it is necessary to replace the oil medium inside the arc extinguishing tube body 1, the integrity of the cleaning of the oil medium can be improved, and the situation that the oil medium containing impurities stays inside the arc extinguishing tube body 1 can be reduced.

[0043] Embodiment 3

[0044] As Figure 3 shown, a connecting rod 30 is fixedly connected to the middle of the support rod 6. The rotation of the support rod 6 can drive the connecting rod 30 to rotate. A stirring blade 31 is fixedly connected to the end of the connecting rod 30, which can stir the oil medium inside the arc extinguishing tube body 1. A plurality of round holes 32 are provided in the middle of the stirring blade 31. The oil medium pushed in the middle of the stirring blade 31 can flow through the middle of the round holes 32.

[0045] Through the rotation of the stirring blade 31, the oil medium inside the arc extinguishing tube body 1 can be stirred. Thus, when eliminating the arc, the situation of local overheating of the oil medium can be reduced. Through the function of the round hole 32, when using the stirring blade 31 to stir the oil medium inside the arc extinguishing tube body 1, the thrust in the middle of the stirring blade 31 can be reduced, thereby improving the stirring rate of the oil medium inside the arc extinguishing tube body 1.

[0046] A hollow tube 28 is fixedly connected to the middle of the arc extinguishing gasket 5, which can absorb the heat generated in the middle of the arc extinguishing gasket 5 due to arc elimination. A plurality of heat dissipation fins 29 are fixedly connected to the middle of the arc extinguishing tube body 1. The end of the hollow tube 28 is fixedly connected to the heat dissipation fin 29, and the heat dissipation fin 29 can transfer the heat in the middle of the hollow tube 28 to the outside.

[0047] When using the arc extinguishing gasket 5 to eliminate the arc generated at the end of the first disc 4, the heat generated in the middle of the arc extinguishing gasket 5 can be absorbed through the hollow tube 28, and then the heat can be transferred to the heat dissipation fin 29 through the hollow tube 28, thereby dissipating heat from the arc extinguishing gasket 5 and reducing the situation of overheating of the arc extinguishing gasket 5 during the arc elimination process.

[0048] Embodiment 4

[0049] As Figures 2 to 7 shown, an arc-shaped cavity 33 is opened at the bottom of the support rod 6. A screw rod 34 is rotatably connected to the middle of the arc-shaped cavity 33. A transmission pull rod 35 is fixedly connected to the end of the screw rod 34. A metal rod 36 is fixedly connected to the end of the transmission pull rod 35. A clamping component is arranged in the middle of the metal rod 36.

[0050] When it is necessary to replace the oil medium inside the arc extinguishing tube body 1, the arc extinguishing tube body 1 can be removed from the middle of the metal rod 36. At this time, the metal rod 36 can be rotated, and then through the transmission of the transmission pull rod 35, the screw rod 34 can be rotated in the middle of the support rod 6, and then the support rod 6 can be removed from the end of the metal rod 36. When connecting the metal rod 36 and the support rod 6, the support rod 6 and the metal rod 36 can be fixed through the clamping component.

[0051] A plurality of arc-shaped elastic pieces 37 are fixedly connected to the middle of the metal rod 36. A limiting piece 38 is fixedly connected to the end of the arc-shaped elastic piece 37. The limiting piece 38 is slidably connected to the arc-shaped cavity 33.

[0052] When placing the screw rod 34 inside the support rod 6 for rotation, the limiting piece 38 can be used to contact the bottom of the support rod 6. Then, during the rotation of the screw rod 34, the arc-shaped elastic piece 37 can gradually fit with the inner side wall of the arc-shaped cavity 33, thereby improving the stability of the connection between the metal rod 36 and the support rod 6 and reducing the situation of mutual separation between the support rod 6 and the metal rod 36 during the working process.

[0053] When performing a power-off process, the arc can be eliminated by the sufficient oil medium filled inside the arc extinguishing tube body. After long-term use, more impurities will be generated inside the oil medium in the middle of the arc extinguishing tube body. At this time, the cleaning component can be used to clean the impurities adhered to the middle of the arc extinguishing gasket, thereby reducing the situation where the accumulation of impurities in the middle of the arc extinguishing gasket affects the elimination of the arc. The cleaning component at the inner bottom of the arc extinguishing tube body can clean the impurities at the bottom of the arc extinguishing tube body to the outside, thereby reducing the situation where the elimination of the arc is affected due to a large amount of impurities in the oil medium when using the oil medium to eliminate the arc. When it is necessary to clean the impurities adhered to the middle of the arc extinguishing gasket, the transmission component can transmit kinetic energy to the rotating groove through the sliding groove, and then the collar can rotate in the middle of the rotating groove. Furthermore, through the supporting action of the connecting rod, the cleaning brush can slide in the middle of the arc extinguishing gasket, thereby cleaning the impurities adhered to the middle of the arc extinguishing gasket by the cleaning brush, reducing the situation where the adhesion of impurities in the middle of the arc extinguishing gasket affects the elimination of the arc. When it is necessary to make the cleaning brush clean the impurities adhered to the middle of the arc extinguishing gasket, the rotating rod can be rotated by turning the torsion, and then through the fixed connection between the transmission piece and the collar, the collar can rotate in the middle of the rotating groove, so that the cleaning brush can be driven by the connecting rod to slide in the middle of the arc extinguishing gasket. Furthermore, when it is not necessary to take out the oil medium inside the arc extinguishing tube body, the impurities adhered to the middle of the arc extinguishing gasket can be cleaned, reducing the situation where a large amount of impurities in the oil medium affect the elimination of the arc. When there are more impurities in the oil medium inside the arc extinguishing tube body, the rubber plug can be taken out from the middle of the guide hole, and then the support rod can be rotated. Then, the cleaning plate at the end of the sweeping rod can clean the impurities accumulated at the bottom of the arc extinguishing tube body, and then the impurities can be cleaned out of the inside of the arc extinguishing tube body through the guide hole. Furthermore, when it is necessary to replace the oil medium inside the arc extinguishing tube body, the situation of residual impurities inside the arc extinguishing tube body can be reduced, and further the situation of affecting the arc elimination can be reduced. When the end of the first disc is in contact with the end of the second disc, the elastic piece can be first in contact with the end of the second disc, and then during the process of the first disc and the second disc approaching each other, the pressing block can squeeze the spring, and then the pressing block can slowly enter the inside of the snap ring. During the process of the elastic piece contacting the second disc, the oil medium between their contact surfaces will be gradually squeezed outwards, thereby reducing the situation of poor contact due to a large amount of oil medium in the middle after the first disc and the second disc are in contact. When it is necessary to replace the oil medium inside the arc extinguishing tube body, through the action of the conical pad, the situation where the oil medium inside the arc extinguishing tube body stays in the middle of the arc extinguishing tube body can be reduced. Through the action of the guide groove, the oil medium can flow relatively quickly to the bottom of the arc extinguishing tube body, and then through the rotating action of the cleaning plate, the oil medium can be discharged to the outside through the guide hole. Furthermore, when it is necessary to replace the oil medium inside the arc extinguishing tube body,It can improve the integrity of the cleaning of the oil medium, reduce the situation where the oil medium containing impurities stays inside the arc extinguishing tube body. Through the rotation of the stirring blade, the oil medium inside the arc extinguishing tube body can be agitated. Furthermore, when eliminating the arc, the situation of local overheating of the oil medium can be reduced. Through the function of the round hole, when using the stirring blade to stir the oil medium inside the arc extinguishing tube body, the thrust in the middle of the stirring blade can be reduced, and thus the stirring rate of the oil medium inside the arc extinguishing tube body can be increased. When using the arc extinguishing gasket to eliminate the arc generated at the end of the first disc, the heat generated in the middle of the arc extinguishing gasket can be absorbed through the hollow tube, and then the heat can be transferred to the heat dissipation fins through the hollow tube, thereby dissipating heat from the arc extinguishing gasket and reducing the situation of excessive temperature of the arc extinguishing gasket during the arc elimination process. When it is necessary to replace the oil medium inside the arc extinguishing tube body, the arc extinguishing tube body can be removed from the middle of the metal rod. At this time, the metal rod can be rotated, and through the transmission of the transmission pull rod, the screw can be rotated in the middle of the support rod, and then the support rod can be removed from the end of the metal rod. When connecting the metal rod and the support rod, the support rod and the metal rod can be fixed through the clamping assembly. When placing the screw inside the support rod and rotating it, the limiting piece can be used to contact the bottom of the support rod. Then, during the rotation of the screw, the arc-shaped elastic piece and the inner side wall of the arc-shaped cavity can gradually fit together, thereby improving the stability when connecting the metal rod and the support rod and reducing the situation of separation between the support rod and the metal rod during the working process.,
