[0002] Outdoor high-voltage vacuum circuit breakers are high-voltage switchgear used in power systems, particularly in outdoor environments. They are primarily used to interrupt and close load currents, no-load currents, and short-circuit currents in high-voltage circuits, ensuring safe and stable operation of the power system. Using vacuum as the arc-extinguishing medium, these circuit breakers offer advantages such as strong arc-extinguishing capability and a long electrical life. They are widely used in power plants, substations, and distribution systems in industrial and mining enterprises.

[0003] In the prior art, when installing a bushing insulator, workers generally use screws to install the bushing insulator on the base. However, since outdoor high-voltage vacuum circuit breakers are installed outdoors, the screws will corrode and rust over time.

[0013] Furthermore, the fixing mechanism includes a telescopic frame, the lower surface of the inner wall of the telescopic frame is fixedly connected to a limit spring, the upper surface of the inner wall of the telescopic frame is fixedly connected to a reset telescopic rod, and the surface of the reset telescopic rod is fixedly connected to an extrusion plate.

[0014] Furthermore, the end of the telescopic frame is fixedly connected to both sides of the movable plate, the end of the limit spring away from the telescopic frame is fixedly connected to both sides of the base, the two ends of the elastic plate are fixedly connected to the surface of the extrusion plate, and the number of the reinforcement rings is two, and the two reinforcement rings are symmetrically arranged with the sleeve insulator as the center.

[0015] Furthermore, the quick-release mechanism includes a groove box, the inner wall of the groove box is slidably connected to a slider, the surface of the slider is rotatably connected to a push plate, the end of the push plate away from the slider is rotatably connected to a press plate, the bottom of the press plate is fixedly connected to a supporting elastic rod, the surface of the clamping ring is fixedly connected to a telescopic elastic rod, the inner wall of the telescopic frame is fixedly connected to a driven rod, and the end of the driven rod away from the telescopic frame is fixedly connected to a slot column.

[0017] The present invention has the following beneficial effects:

[0018] The present invention provides an installation mechanism. First, the first or second sleeve insulator is placed on the inner wall of the installation sleeve so that the installation ring contacts the surface of the stress ring. Then, the first sleeve insulator is pressed to move downward, and the installation ring is driven to move downward so that the end of the first sleeve insulator passes through the installation hole and the downward pressure hole and extends to the same level as the fixing ring. At this time, the installation ring squeezes the stress ring and moves downward. When the stress ring is squeezed, the stress elastic rod is squeezed downward, causing the stress elastic rod to contract downward. When the stress ring moves downward, it drives the support The lifting plate moves downward, and the supporting lifting plate pushes the slide to slide downward on the inner wall of the groove frame. When the slide slides, it pushes the installation rod to move in the direction of approaching each other. When the installation rod moves, it pushes the movable plate to slide in the direction of approaching each other on the surface of the groove frame. When the movable plate slides, it drives the fixing ring to move in the direction of approaching each other, thereby contacting and fixing the end of the sleeve insulator one, effectively fixing the end of the sleeve insulator one through the movable plate, thereby achieving the effect of quick installation, thereby replacing the tedious steps of screw installation and improving the efficiency of installation.

[0019] The present invention is provided with a fixing mechanism. When the movable plate slides, the telescopic frame is driven to retract in the direction of approaching each other. When the telescopic frame retracts, the limit spring is squeezed. When the limit spring is squeezed, the telescopic frame is retracted in the direction of approaching each other. When the telescopic frame is retracted into place, the telescopic frame is limited, thereby preventing the telescopic frame from contacting the base. When the telescopic frame retracts, the reset telescopic rod is pushed to retract in the direction of approaching each other. When the reset telescopic rod is squeezed, the extrusion plate products are driven to move in the direction of approaching each other, and the extrusion plate is squeezed against the elastic plate. When the elastic plate is squeezed, the middle part is bent. When the middle part of the elastic plate is bent, the buffer elastic rod is pushed to move in the direction of approaching each other. When the buffer elastic rod moves, the reinforcement ring is pushed to move in the direction of approaching each other and contact the surface of the sleeve insulator 1, thereby fixing the sleeve insulator 1. When the reinforcement ring contacts the surface of the sleeve insulator 1, it remains stationary, and the elastic plate continues to push the buffer elastic rod to retract in the direction of approaching each other, thereby strengthening the supporting force of the reinforcement ring. The sleeve insulator 1 is effectively reinforced by the reinforcement ring, making the sleeve insulator 1 more stable during use.

[0020] The present invention provides a quick-release mechanism. When the telescopic frame moves, it pushes the driven rod to move in the direction of approaching each other. At the same time, the driven rod pushes the slot column to move in the direction of approaching each other. During the movement of the slot column, it contacts the surface of the clamping ring and squeezes the clamping ring. When the clamping ring is squeezed, it moves in the direction of moving away from each other and pushes the telescopic elastic rod to shrink in the direction of moving away from each other. When the clamping ring moves, it pulls the connecting rod to move in the direction of moving away from each other. At the same time, the connecting rod drives the driven plate to move in the direction of moving away from each other. When the driven plate moves, it will bring When the movable slider slides on the inner wall of the groove box in the direction away from each other, the slider pulls the push plate to move in the direction away from each other. When the push plate moves, it pulls the press plate downward, and at the same time, the press plate squeezes the supporting elastic rod to make the supporting elastic rod shrink downward. When the slot on the surface of the slot column moves to the same level as the snap ring, the snap ring will contact the inner wall of the slot through the elastic force of the telescopic elastic rod, thereby limiting the slot column. When the slot column is limited, the driven rod will also remain stationary through the limit. Since the installation mechanism and the fixing mechanism are linked, the fixing mechanism is fixed. The telescopic frame and the driven rod in the mechanism are in a fixed relationship. When the driven rod remains stationary, the fixing mechanism and the mounting mechanism will also remain stationary, thereby achieving the effect of quickly installing and limiting the first bushing insulator. When the first bushing insulator needs to be replaced, the staff only needs to press the pressing plate to move downward and retract the supporting elastic rod downward, and at the same time, the push plate will push the slider to slide in the inner wall of the groove box in the direction away from each other. When the slider slides, it will drive the driven plate to move in the direction away from each other, and the driven plate will drive the connecting rod to move in the direction away from each other. When the connecting rod moves, it will drive the clamping ring to move in the direction away from each other. At this time, the clamping ring is separated from the slot, and the telescopic frame will be reset in the direction away from each other by the limit spring. At this time, the telescopic frame will pull the driven rod to reset in the direction away from each other, and the driven rod will pull the slot column to reset in the direction away from each other, and the fixing mechanism and the mounting mechanism will be reset at the same time, thereby ejecting the first bushing insulator, so that the first bushing insulator can be replaced, effectively making the first bushing insulator quickly disassembled, thereby improving the efficiency of replacing the first bushing insulator or the second bushing insulator.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The mounting mechanism 10 includes a groove frame 17. A movable plate 18 is slidably connected to the surface of the groove frame 17. When the mounting rod 16 moves, the movable plate 18 is pushed to slide on the surface of the groove frame 17 in a direction toward each other. A fixing ring 19 is fixedly connected to the surface of the movable plate 18. When the movable plate 18 slides, the fixing ring 19 is driven to move in a direction toward each other, thereby contacting and fixing the end of the bushing insulator 2;

[0039] The fixing mechanism 30 includes an elastic plate 35, and the extrusion plate 34 is used to squeeze the elastic plate 35. When the elastic plate 35 is squeezed, the middle portion thereof bends. A buffer elastic rod 36 is fixedly connected to the surface of the elastic plate 35. When the middle portion of the elastic plate 35 bends, the buffer elastic rod 36 is pushed toward each other. A reinforcement ring 37 is fixedly connected to the end of the buffer elastic rod 36 away from the elastic plate 35. When the buffer elastic rod 36 moves, the reinforcement ring 37 is pushed toward each other and contacts the surface of the bushing insulator 2, thereby fixing the bushing insulator 2.

[0040] The quick release mechanism 50 includes a driven plate 56, and the end of the driven plate 56 is fixedly connected to a connecting rod 57. At the same time, the connecting rod 57 drives the driven plate 56 to move in a direction away from each other. The end of the connecting rod 57 is fixedly connected to a retaining ring 58. When the retaining ring 58 moves, it pulls the connecting rod 57 to move in a direction away from each other.

[0041] One end of the lever 3 away from the bushing insulator 1 2 contacts the inner wall of the main contact 5. A mounting hole is provided on the surface of the base 1. Three bushing insulators 1 2 and three bushing insulators 2 4 are provided. The three bushing insulators 1 2 and three bushing insulators 2 4 are distributed above the base 1.

[0042] When the load ring 13 is pressed, the load ring 13 is pressed downwardly, and the load ring 13 is moved downwardly.

[0043] A pressing hole is provided at the bottom of the inner wall of the mounting sleeve 11. First, place the sleeve insulator 12 or the sleeve insulator 24 on the inner wall of the mounting sleeve 11 so that the mounting ring 6 contacts the surface of the force ring 13. Then, press the sleeve insulator 12 to move the sleeve insulator 12 downward, and drive the mounting ring 6 to move downward, so that the end of the sleeve insulator 12 passes through the mounting hole and the pressing hole, and extends to the same level as the fixing ring 19. The bottom of the mounting sleeve 11 is fixedly connected to the surface of the base 1, the bottom of the mounting ring 6 contacts the surface of the force ring 13, the surface of the slide 15 is slidably connected to the inner wall of the groove frame 17, and the end of the mounting rod 16 away from the slide 15 is rotatably connected to the surface of the movable plate 18. When the slide 15 slides, it pushes the mounting rod 16 to move in a direction close to each other.

[0044] The fixing mechanism 30 includes a telescopic frame 31, and the lower surface of the inner wall of the telescopic frame 31 is fixedly connected to the limit spring 32. When the telescopic frame 31 contracts, the limit spring 32 will be squeezed. When the limit spring 32 is squeezed, it will contract in the direction of approaching each other, and when it is contracted into place, the telescopic frame 31 will be limited, thereby preventing the telescopic frame 31 from contacting the base 1. The upper surface of the inner wall of the telescopic frame 31 is fixedly connected to a reset telescopic rod 33. When the telescopic frame 31 contracts, the reset telescopic rod 33 will be pushed to contract in the direction of approaching each other. The surface of the reset telescopic rod 33 is fixedly connected to an extrusion plate 34. When the reset telescopic rod 33 is compressed, it will drive the extrusion plate 34 to move in the direction of approaching each other, effectively reinforcing the sleeve insulator 2 through the reinforcement ring 37, making the sleeve insulator 2 more stable when in use.

[0045] The ends of the telescopic frame 31 are fixedly connected to the two sides of the movable plate 18. When the movable plate 18 slides, the telescopic frame 31 will be driven to shrink in the direction of approaching each other. The end of the limit spring 32 away from the telescopic frame 31 is fixedly connected to the two sides of the base 1. The two ends of the elastic plate 35 are fixedly connected to the surface of the extrusion plate 34, and this elastic plate 35 will continue to push the buffer elastic rod 36 to shrink in the direction of approaching each other, thereby strengthening the supporting force of the reinforcement ring 37. There are two reinforcement rings 37, and the two reinforcement rings 37 are symmetrically arranged with the sleeve insulator 2 as the center. When the reinforcement ring 37 contacts the surface of the sleeve insulator 2, it will remain motionless.

[0046] The quick-release mechanism 50 includes a groove box 51, and the inner wall of the groove box 51 is slidably connected to a slider 52. When the driven plate 56 moves, it drives the slider 52 to slide on the inner wall of the groove box 51 in the direction of moving away from each other. The surface of the slider 52 is rotatably connected to the push plate 53. At this time, the slider 52 pulls the push plate 53 to move in the direction of moving away from each other. The end of the push plate 53 away from the slider 52 is rotatably connected to the pressing plate 54. The bottom of the pressing plate 54 is fixedly connected to the supporting elastic rod 55. At the same time, the pressing plate 54 squeezes the supporting elastic rod 55 to shrink the supporting elastic rod 55 downward. The surface of the snap ring 58 is fixedly connected to the telescopic elastic rod 59. When the groove on the surface of the groove column 61 moves to the same level as the snap ring 58, the snap ring 58 will contact the inner wall of the groove through the elastic force of the telescopic elastic rod 59. At this time, the snap ring 58 is separated from the groove. The telescopic frame 31 will be reset in the direction of moving away from each other through the limit spring 32. At this time, the telescopic frame 31 will pull the driven rod 60 to reset in the direction of moving away from each other. At the same time, the driven rod 60 will pull the slot column 61 to reset in the direction of moving away from each other, and the fixing mechanism 30 and the mounting mechanism 10 will be reset at the same time, thereby ejecting the sleeve insulator 2, so that the sleeve insulator 2 can be replaced, and the telescopic elastic rod 59 is pushed to shrink in the direction of moving away from each other. The inner wall of the telescopic frame 31 is fixedly connected to the driven rod 60. When the telescopic frame 31 moves, the driven rod 60 will be pushed to move in the direction of moving closer to each other. The end of the driven rod 60 away from the telescopic frame 31 is fixedly connected to the slot column 61, which can effectively quickly disassemble the sleeve insulator 2, thereby improving the efficiency of replacing the sleeve insulator 2 or the sleeve insulator 2 4.

[0047] When the push plate 53 moves, the push plate 54 is pulled downward, and the driven plate 56 is fixedly connected to the bottom of the slider 52 at one end away from the connecting rod 57. The driven plate 56 drives the connecting rod 57 to move in the direction away from each other. When the connecting rod 57 moves, the snap ring 58 is driven to move in the direction away from each other. The end of the telescopic elastic rod 59 away from the snap ring 58 is fixedly connected to the inner wall of the groove box 51. During the movement of the slot column 61, it contacts the surface of the snap ring 58 and squeezes the snap ring 58. When the snap ring 58 is squeezed, it moves in the direction away from each other. The bottom of the groove box 51 is fixedly connected to the surface of the base 1. When the sleeve insulator 2 needs to be replaced, the staff only needs to press the press plate 54 to move downward and move the supporting elastic rod 55 When the slider 52 slides, it drives the driven plate 56 to move in the direction away from each other, and the driven rod 60 approaches one end of the slot column 61. At the same time, the driven rod 60 pushes the slot column 61 to move in the direction of approaching each other, thereby limiting the slot column 61. When the slot column 61 is limited, the driven rod 60 will also remain stationary through the limit. Since the installation mechanism 10 and the fixing mechanism 30 are in a linkage relationship, and the telescopic frame 31 in the fixing mechanism 30 and the driven rod 60 are in a fixed relationship, when the driven rod 60 remains stationary, the fixing mechanism 30 and the installation mechanism 10 will also remain stationary, thereby achieving the effect of quickly installing and limiting the bushing insulator 2, and the surface of the groove box 51 is fixedly connected to the end of the slot column 61.

[0048] When in use, first place the sleeve insulator 12 or the sleeve insulator 24 on the inner wall of the installation sleeve 11, so that the installation ring 6 contacts the surface of the force ring 13, and then press the sleeve insulator 12 to move the sleeve insulator 12 downward, and drive the installation ring 6 to move downward, so that the end of the sleeve insulator 12 passes through the installation hole and the downward pressure hole, and extends to the same level as the fixing ring 19. At this time, the installation ring 6 will squeeze the force ring 13 to move downward. When the force ring 13 is squeezed, it will squeeze the force elastic rod 12 downward, causing the force elastic rod 12 to shrink downward. When the force ring 13 moves downward, it will drive the support lifting plate 14 to move downward, and the support lifting plate 14 will push the slide 15 to slide downward on the inner wall of the groove frame 17. When the slide 15 slides, The mounting rod 16 is pushed to move in the direction of approaching each other. When the mounting rod 16 moves, the movable plate 18 is pushed to slide on the surface of the groove frame 17 in the direction of approaching each other. When the movable plate 18 slides, the fixing ring 19 is driven to move in the direction of approaching each other, thereby contacting and fixing the end of the bushing insulator 2. When the movable plate 18 slides, the telescopic frame 31 is driven to retract in the direction of approaching each other. When the telescopic frame 31 retracts, the limit spring 32 is squeezed. When the limit spring 32 is squeezed, it retracts in the direction of approaching each other, and when it retracts into place, the telescopic frame 31 is limited, thereby preventing the telescopic frame 31 from contacting the base 1. When the telescopic frame 31 retracts, the reset telescopic rod 33 is pushed to retract in the direction of approaching each other. When the reset telescopic When the shrink rod 33 is compressed, it will drive the extrusion plate 34 to move in the direction of approaching each other, and make the extrusion plate 34 squeeze the elastic plate 35. When the elastic plate 35 is squeezed, the middle part will bend. When the middle part of the elastic plate 35 bends, it will push the buffer elastic rod 36 to move in the direction of approaching each other. When the buffer elastic rod 36 moves, it will push the reinforcement ring 37 to move in the direction of approaching each other and contact the surface of the sleeve insulator 2, thereby fixing the sleeve insulator 2. When the reinforcement ring 37 contacts the surface of the sleeve insulator 2, it will remain stationary, and this elastic plate 35 will continue to push the buffer elastic rod 36 to shrink in the direction of approaching each other, thereby strengthening the supporting force of the reinforcement ring 37. When the telescopic frame 31 moves, it will push the driven rod 60 When the clamping ring 58 is squeezed, it will move in the direction of moving away from each other and push the telescopic elastic rod 59 to shrink in the direction of moving away from each other. When the clamping ring 58 moves, it will pull the connecting rod 57 to move in the direction of moving away from each other. At the same time, the connecting rod 57 will drive the driven plate 56 to move in the direction of moving away from each other. When the driven plate 56 moves, it will drive the slider 52 to slide on the inner wall of the groove box 51 in the direction of moving away from each other. At this time, the slider 52 pulls the push plate 53 to move in the direction of moving away from each other. When the push plate 53 moves, it will pull the press plate 54 to move downward.At the same time, the pressing plate 54 will squeeze the supporting elastic rod 55, causing the supporting elastic rod 55 to retract downward. When the groove on the surface of the slot column 61 moves to the same level as the snap ring 58, the snap ring 58 will use the elastic force of the telescopic elastic rod 59 to make the snap ring 58 contact the inner wall of the groove, thereby limiting the slot column 61. When the slot column 61 is limited, the driven rod 60 will also remain stationary through the limit. Since the installation mechanism 10 and the fixing mechanism 30 are in a linkage relationship, and the telescopic frame 31 in the fixing mechanism 30 and the driven rod 60 are in a fixed relationship, when the driven rod 60 remains stationary, the fixing mechanism 30 and the installation mechanism 10 will also remain stationary, thereby achieving the effect of quickly installing and limiting the sleeve insulator 2. When the sleeve insulator 2 needs to be replaced, the staff only needs to press the pressing plate 54 downward The movement causes the supporting elastic rod 55 to contract downward, and at the same time, the push plate 53 pushes the slider 52 to slide away from each other on the inner wall of the groove box 51. When the slider 52 slides, it drives the driven plate 56 to move away from each other. The driven plate 56 drives the connecting rod 57 to move away from each other. When the connecting rod 57 moves, it drives the snap ring 58 to move away from each other. At this time, the snap ring 58 separates from the slot, and the telescopic frame 31 is reset in the direction of separation by the limit spring 32. At this time, the telescopic frame 31 pulls the driven rod 60 to reset in the direction of separation. At the same time, the driven rod 60 pulls the slot column 61 to reset in the direction of separation. The fixing mechanism 30 and the installation mechanism 10 are reset at the same time, thereby ejecting the sleeve insulator 2, so that the sleeve insulator 2 can be replaced.
