Description

Technical Field

[0001] This utility model relates to the field of high-voltage outdoor disconnect switch technology, specifically a fully enclosed high-voltage outdoor disconnect switch. Background Technology

[0002] High-voltage outdoor disconnect switches are outdoor equipment used in high-voltage power systems. They are mainly used to disconnect or switch lines under voltage and no-load conditions. Their core function is to provide a safe and isolated power supply environment for maintenance personnel. High-voltage disconnect switches are mainly used in the electrical systems of power plants and substations to disconnect or switch lines, thereby isolating voltage and ensuring the safety of high-voltage electrical appliances and equipment during maintenance.

[0003] For example, the fully enclosed outdoor high-voltage disconnect switch disclosed in the authorization announcement number CN221407153U includes a housing, the top of the housing has a square slot, the inner wall of the housing is rotatably connected to an optical shaft, one end of the optical shaft is fixedly connected to a baffle, the inner wall of the housing is snapped with an insulator, the top of the insulator is fixedly connected to two straight plates, and one side of the two straight plates has a circular slot. Although it eliminates the danger of workers having to physically contact the high-voltage disconnect switch through the airbag pushing mechanism and connecting plate, when power needs to be connected, workers only need to manually pull the hook rod, which is engaged with the inner wall of the annular plate. When workers need to disconnect the high-voltage disconnect switch, after maintaining a safe distance from the high-voltage disconnect switch, they connect the inflator and hose, and then inflate the airbag. The airbag then expands, pushing the hook rod away from the annular plate. When the spring is twisted, the connecting plate flips upward, achieving the power disconnection effect. The operation steps are simple, increasing the safety of the high-voltage disconnect switch. However, this does not solve the problem that existing high-voltage outdoor disconnect switches are generally not convenient for controlling the power supply of the switch circuit, making it difficult to easily disconnect unused circuits, affecting the labor intensity of manual workers, the stability of line connections, the practicality of the high-voltage outdoor disconnect switches, and the safety of the high-voltage outdoor disconnect switches during use.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high-voltage outdoor disconnect switch not only realizes the convenient control switch circuit for power supply, but also facilitates the convenient disconnection of unused circuits, reduces manual labor intensity, and increases the stability of line connection, but also improves the practicality of the high-voltage outdoor disconnect switch and the safety of the high-voltage outdoor disconnect switch during use. (1) The partition divides the enclosed box into two chambers, each containing a set of disconnect switches. The second wire body passes through the first sealing ring and connects to the terminal block. The first wire body passes through the second sealing ring and connects to the outlet plate. The first and second sealing rings serve as seals. The first servo motor drives the rotating column to rotate, so that the rotating column rotates to the required angle.

The door 2 is symmetrically installed on the side wall of the enclosed enclosure 1. Two sets of first through holes 3 are provided on the side wall of the enclosed enclosure 1 below the door 2. Two sets of support seats 4 are provided on the side wall of the enclosed enclosure 1 below the first through holes 3. A first servo motor 5 is installed on the side wall of the enclosed enclosure 1 away from the door 2. An observation window 8 is installed on the side wall of the enclosed enclosure 1 above the first servo motor 5. A partition 6 is installed inside the enclosed enclosure 1. A support frame 7 is installed at the bottom of the enclosed enclosure 1. A rotating column 9 is installed at the output end of the first servo motor 5. The rotating column 9 extends through the support frame 7 and is movably connected to its exterior. First insulators 10 are symmetrically installed at the top of the support frame 7. Second insulators 11 are symmetrically installed on the side of the top of the support frame 7 away from the first insulator 10. Two sets of connecting plates 13 are mounted on the surface of the first insulator 10. A rotating shaft 12 is movably mounted on the surface of each connecting plate 13. A connecting plate 14 is mounted on the surface of each rotating shaft 12. A rotating shaft 19 is movably mounted on the side of the connecting plate 14 away from the rotating shaft 12. A terminal plate 15 is mounted on the top of each first insulator 10. A second wire body 31 is mounted on the side wall of each terminal plate 15. The second wire body 31 extends through the first through hole 3 through the closed box 1 to its outside. A third shaft 39 is movably mounted on the top of each terminal plate 15. A rotating frame 16 is mounted on the surface of each third shaft 39. A support shaft 17 is movably mounted inside each rotating frame 16. A moving contact 18 is mounted on the surface of each support shaft 17. The bottom end of each moving contact 18 is movably connected to the connecting plate 14 through the rotating shaft 19. A contact plate 20 is mounted on the top of each rotating frame 16. A wire outlet plate 22 is provided on the outside of each second insulator 11. All surfaces of the outlet plate 22 are equipped with stationary contacts 21, and all surfaces of the outlet plate 22 on one side of the stationary contacts 21 are equipped with contact blocks 27. All side walls of the outlet plate 22 are equipped with first wire bodies 24, and two sets of second through holes 25 are installed on the side walls of the enclosed box 1. The first wire body 24 extends through the second through hole 25 through the closed box 1 to the outside. The first through hole 3 is fitted with a first sealing ring 30. The second wire body 31 is in contact with the first sealing ring 30. The second through hole 25 is fitted with a second sealing ring 32. The first wire body 24 is in contact with the second sealing ring 32. When using a fully enclosed high-voltage outdoor disconnect switch, partition 6 divides the enclosed housing 1 into two chambers, each housing a set of disconnect switches. The second wire body 31 passes through the first sealing ring 30 and connects to the terminal block 15. The first wire body 24 passes through the second sealing ring 32 and connects to the outlet plate 22. The first sealing ring 30 and the second sealing ring 32 serve a sealing function. The operator operates the external control panel and activates the first servo motor 5 via the controller. Supported by the enclosed housing 1, the first servo motor 5 drives the rotating column 9 to rotate to the required angle. The moving connecting plate 13 rotates, and the connecting plate 14 rotates via the rotating shaft 12. Under the limiting support of the support shaft 17, the connecting plate 14 rotates via the rotating shaft 19, so that the moving contact 18 contacts the stationary contact 21 to supply power. At the same time, the moving contact 18 rotates via the support shaft 17 to drive the rotating frame 16 to rotate around the third shaft 39, so that the rotating frame 16 drives the contact plate 20 to contact the contact block 27 to supply power. This realizes the convenient control switch circuit of the high-voltage outdoor disconnect switch to supply power, and improves the safety of the high-voltage outdoor disconnect switch during use. The top of each second insulator 11 is equipped with a second servo motor 26, and the output end of each second servo motor 26 is equipped with a support plate 23. The support plate 23 is connected to the outgoing plate 22. When one group needs to be powered while the other is de-energized, the external control panel is operated to activate the second servo motor 26 of the other group. This causes the second servo motor 26 to rotate to the required angle. Supported by the second insulator 11, the second servo motor 26 drives the support plate 23 to rotate. The support plate 23 then drives the outgoing plate 22, stationary contact 21, and contact block 27 to rotate to a certain angle, causing the stationary contact 21 and contact block 27 to move to one side, away from the contact area. This allows the high-voltage outdoor disconnect switch to conveniently disconnect unused circuits, reducing manual labor intensity and improving the practicality of the high-voltage outdoor disconnect switch. The top of each support base 4 is equipped with a lower buckle 29, and a first shaft 33 is movably installed on one side of each lower buckle 29. An upper buckle 34 is fitted on the surface of each first shaft 33, and a second shaft 37 is movably installed on the other side of each lower buckle 29. The surface of the second shaft 37 is fitted with threaded rods 28, and the side wall of the upper buckle 34 is provided with U-shaped grooves 38. The outside of the upper buckle 34 is provided with pads 36, and the outside of the pads 36 is provided with nuts 35. The nuts 35 are threadedly connected to the threaded rods 28. When it is necessary to fix the second wire body 31 and the first wire body 24, flip the upper buckle 34. With the support of the first shaft 33, the upper buckle 34 rotates around the first shaft 33, so that the upper buckle 34 is locked onto the surface of the lower buckle 29, fixing and limiting the second wire body 31 and the first wire body 24. Rotate the threaded rod 28. With the movable support of the second shaft 37, the threaded rod 28 rotates into the inside of the U-shaped groove 38. Place the pad 36 on top of the U-shaped groove 38 and screw the nut 35 onto the surface of the threaded rod 28. With the threaded connection between the threaded rod 28 and the nut 35, the nut 35 presses the upper buckle 34 and the lower buckle 29 together, realizing convenient fixing of the first wire and the second wire of the high-voltage outdoor disconnect switch, avoiding short circuits when dragged, and increasing the stability of the line connection.

[0018] Working principle: When using a fully enclosed high-voltage outdoor disconnect switch, the partition 6 divides the enclosed housing 1 into two chambers, each housing a set of disconnect switches. The second wire body 31 passes through the first sealing ring 30 and connects to the terminal block 15. The first wire body 24 passes through the second sealing ring 32 and connects to the outlet plate 22. The first sealing ring 30 and the second sealing ring 32 provide a seal. The first servo motor 5 drives the rotating column 9 to rotate to the required angle. The rotating column 9 drives the connecting plate 13 to rotate. 3. The connecting plate 14 is rotated by the rotating shaft 12. Under the limiting support of the support shaft 17, the connecting plate 14 drives the moving contact 18 to rotate via the rotating shaft 19, so that the moving contact 18 contacts the stationary contact 21 to supply power. At the same time, the moving contact 18 drives the rotating frame 16 to rotate around the third shaft 39 via the support shaft 17, so that the rotating frame 16 drives the contact plate 20 to contact the contact block 27 to supply power. When it is necessary to supply power to one group and de-energize the other group, the external control panel is operated to open the other group through the controller. Two servo motors 26 rotate the second servo motor 26 to the required angle. Supported by the second insulator 11, the second servo motor 26 drives the support plate 23 to rotate. The support plate 23 drives the lead plate 22, stationary contact 21, and contact block 27 to rotate a certain angle, causing the stationary contact 21 and contact block 27 to move to one side, away from the contact area. When it is necessary to fix the second wire body 31 and the first wire body 24, the upper buckle 34 is flipped. Supported by the first shaft 33, the upper buckle 34 rotates around the first shaft 33. Rotate the switch so that the upper latch 34 engages with the surface of the lower latch 29, fixing and limiting the second wire body 31 and the first wire body 24. Rotate the threaded rod 28, and under the movable support of the second shaft 37, rotate the threaded rod 28 into the interior of the U-shaped groove 38. Place the pad 36 above the U-shaped groove 38 and screw the nut 35 onto the surface of the threaded rod 28. With the threaded connection between the threaded rod 28 and the nut 35, the nut 35 presses the upper latch 34 and the lower latch 29 together to complete the operation of the high-voltage outdoor disconnect switch.
