Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, specifically to an operating mechanism for a disconnecting switch and a disconnecting switch. Background Technology

[0002] Disconnect switches are crucial switching devices in power systems, primarily used to open and close circuits under no-load current conditions. This isolates high-voltage busbars, electrical equipment, and lines, providing a visible disconnect point for maintenance personnel and ensuring operational safety. In substations, especially open-type outdoor substations, double-pole or triple-pole disconnect switches are widely used due to their simple structure and high reliability. Existing disconnect switches typically design the opening / closing mechanism and the grounding mechanism as two completely independent systems, each equipped with its own drive source, transmission chain, and actuators. This not only increases the overall size and weight of the equipment, raising manufacturing costs, but also occupies valuable outdoor installation space. Furthermore, in some outdoor substations with limited installation space, the grounding connection rod needs to complete a transition from an inclined to a vertical position within a confined space to achieve reliable contact with the grounding rod. Moreover, the grounding drive mechanism often uses a simple direct push-pull method, which struggles to provide sufficient travel and contact pressure within limited space, resulting in excessively high grounding circuit resistance and affecting the reliability of grounding protection. Summary of the Invention

[0003] The purpose of this invention is to provide an operating mechanism and a disconnecting switch for a disconnecting switch, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an operating mechanism for a disconnecting switch, comprising: Multiple support crossbars; Rotary support insulators 1 and 2 are placed at both ends of the support crossbar. The bottoms of two adjacent support insulators 2 are connected by transmission rod 4. The bottoms of support insulators 1 and 2 are connected diagonally by transmission rod 2. A switch 1 is fixedly connected to the top of support insulator 1. A switch 2 that cooperates with switch 1 is fixedly connected to the top of support insulator 2. A grounding rod is fixedly connected to the top of both support insulators 1 and 2. An operating component is located below the support crossbar. The operating component includes a drive tube for driving the opening and closing of the circuit breaker and grounding, and a turntable wheel. A drive unit is provided below the turntable wheel for driving the turntable wheel to rise, fall and rotate.

[0005] Preferably, the bottom of the support crossbar is fixedly connected to a mounting base rod, the end of the mounting base rod is fixedly connected to a support plate, the middle of the support plate is rotatably connected to a rotating shaft one, a rotating shaft two and a rotating shaft three, the rotating shaft three is fixedly connected to the bottom of the post insulator two, and one end of the switch one is fixedly connected to a limiting piece that cooperates with the end of the switch two.

[0006] Preferably, the two ends of the supporting crossbar are rotatably connected to a grounding rotating rod one and a grounding rotating rod two, and the outer sides of the grounding rotating rod one and the grounding rotating rod two are fixedly connected to a grounding connecting rod that cooperates with the grounding rod.

[0007] Preferably, a crank is fixedly connected to the top of the rotating shaft, a transmission rod is rotatably connected to the top of the crank, a connecting rod is rotatably connected to the end of the transmission rod, and the connecting rod is fixedly connected to the grounding rotating rod, which is used to drive the grounding rotating rod to adjust its elevation angle when the rotating shaft rotates horizontally.

[0008] Preferably, a crank is fixedly connected to the top of the second rotating shaft, a transmission rod is rotatably connected to the top of the crank, a connecting rod is rotatably connected to one end of the transmission rod, and the connecting rod is fixedly connected to the grounded rotating rod, which is used to drive the grounded rotating rod to adjust its elevation angle when the second rotating shaft rotates horizontally.

[0009] Preferably, a transmission box is provided below the mounting base rod, and the first, second and third rotating shafts are all rotatably connected to the transmission box, with a drive tube fixedly connected to the middle of each of the first, second and third rotating shafts.

[0010] Preferably, the bottom of the first, second, and third rotating shafts are all fixedly connected to a rotating disk, and multiple lifting slide rods are vertically slidably connected to the outer side of the rotating disk. A spring is sleeved on the outer side of the lifting slide rod to drive the lifting slide rod to move downward. The middle of the actuating wheel has multiple notches that cooperate with the lifting slide rods.

[0011] Preferably, the drive unit includes a linear module fixed inside the transmission box. A support frame is fixedly mounted on the moving slide of the linear module. A geared motor is fixedly mounted on the outer side of the support frame. A drive shaft is provided in the middle of the support frame.

[0012] A disconnect switch includes the operating mechanism described above.

[0013] Compared with existing technologies, the advantages of this invention are: Diagonal linkage between post insulator one and post insulator two is achieved through transmission rod two. The double-stage linkage synchronous structure ensures that all switch one and switch two can complete opening and closing actions strictly synchronously on multiple support crossbars arranged over a long distance, eliminating the risk of three-phase imbalance or arcing caused by asynchronous actions in multi-break operations, and improving the stability and electrical life of the high-voltage disconnector. Manual and electric switching is achieved through the drive tube and drive unit, allowing for selection of the appropriate operating mode in different environments. A linear module is responsible for station selection, and the repulsive force between the electromagnet and permanent magnet, combined with spring two, achieves automatic lifting and disengagement of the actuating wheel. A geared motor provides precise rotational drive. This simplifies the mechanism's complexity. During the actuating wheel's ascent, the lifting slide is compressed and retracted; only when the notch and slide are precisely aligned does it spring into engagement under spring force, achieving reliable engagement without requiring extremely high positioning accuracy. After operation, the electromagnet is de-energized, and the actuating wheel automatically descends and disengages under spring force, avoiding wear caused by long-term engagement.

[0016] 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.

[0017] Please see Figures 1-6 The present invention provides a technical solution: an operating mechanism for a disconnecting switch, comprising: multiple supporting crossbars 2; rotatably mounted post insulators 3 and 6 at both ends of the supporting crossbars 2, with the bottoms of two adjacent post insulators 6 connected by a transmission rod 33, so that while one post insulator 6 is driven to rotate, the transmission rod 33 drives the other post insulators 6 to rotate synchronously, and the bottoms of post insulators 3 and 6 are diagonally connected by a transmission rod 16, through the transmission of the transmission rod 16. The counterclockwise rotation of post insulator 26 causes post insulator 13 to rotate counterclockwise, thereby closing the circuit breaker 27 and the circuit breaker 14. The top of post insulator 13 is fixedly connected to the circuit breaker 14, and the top of post insulator 26 is fixedly connected to the circuit breaker 27 that cooperates with the circuit breaker 14. The tops of post insulator 13 and post insulator 26 are both fixedly connected to the grounding rod 8. When the circuit breaker 14 and the circuit breaker 27 are aligned, the grounding rod 8 is misaligned with the grounding structure. When the circuit breaker 14 and the circuit breaker 27 are separated, the grounding rod 8 is aligned with the grounding structure. The operating assembly is located below the support crossbar 2. The operating assembly includes a drive tube 29 for driving the opening and closing of the circuit breaker and grounding, and a turntable 23. A drive unit is provided below the turntable 23 for driving the turntable 23 to rise, fall and rotate.

[0018] It should be noted that in this embodiment, a PLC controller and an operation panel are provided. The bottoms of two adjacent post insulators 2 and 6 are connected by a transmission rod 4 and 33. When one of the post insulators 2 and 6 is driven to rotate, the transmission rod 4 and 33 transmit the power to the other post insulators 2 and 6, thereby realizing the synchronous rotation of multiple post insulators 2 and 6. The post insulators 1 and 3 located on the same support crossbar 2 are connected diagonally at their bottoms by a transmission rod 2 and 16. This transmission rod 2 and 16 constitute the motion link between the two, so that their rotations maintain a linkage relationship. The switch 1 and switch 2 and 7 cooperate to form the on / off node of the main conductive circuit. A fixed grounding structure is also provided above the support crossbar 2. The grounding rod 8 rotates synchronously with the insulator, and its trajectory determines whether it contacts the grounding structure. The operating component is located below the support crossbar 2 and includes a drive tube 29 and a toggle wheel 23. A drive unit is located below the actuating wheel 23, which drives the actuating wheel 23 to perform lifting and rotating movements, thereby controlling the movement of the post insulator 26, the grounding rotating rod 19, and the grounding rotating rod 219. The drive unit controls the actuating wheel 23 to move to a designated position, then rises and rotates. The rotation of the actuating wheel 23 drives the rod corresponding to the post insulator 26 to rotate, acting on one of the post insulators 26, causing it to rotate counterclockwise around its axis. Since the bottom of the post insulator 26 is connected to the transmission rod 433, this rotation is transmitted to the adjacent post insulator 26 through the transmission rod 433, achieving synchronous counterclockwise rotation of all post insulators 26. Simultaneously, since the post insulator 13 and post insulator 26 are diagonally connected by the transmission rod 216, the counterclockwise rotation of post insulator 26 pulls post insulator 13 through the transmission rod 216, causing post insulator 13 to also rotate counterclockwise synchronously. As the post insulators 1-3 and 2-6 rotate, the top switch 1-4 and switch 2-7 gradually approach and eventually engage. In this state, because the grounding rod 8 rotates with the insulators to a specific angle, the grounding rod 8 is in a misaligned and separated state from the preset grounding structure, ensuring that the grounding circuit is disconnected when the main circuit is conducting, thus guaranteeing electrical safety. When the circuit is open, the drive unit controls the actuating wheel 23 to move to the designated position. The actuating wheel 23 drives the transmission structure corresponding to the post insulator 2-6 to move in the opposite direction, driving the post insulator 2-6 to rotate clockwise. Similarly, through the transmission action of the transmission rod 4-33 and the transmission rod 2-16, all post insulators 1-3 and 2-6 rotate clockwise synchronously. The top switch 1-4 and switch 2-7 gradually separate, cutting off the main circuit current. When grounding, based on the open state, the drive unit drives the grounding rotating rod 1-9 or the grounding rotating rod 2-19 to rotate, and the grounding connecting rod 32 rotates to the position corresponding to the grounding rod 8 and makes contact with it. At this time, by connecting the grounding rod 8 to the grounding structure, the voltage on the line side is forcibly grounded, the residual charge is released, and a safe working environment is provided for maintenance personnel.

[0019] In one embodiment, a mounting base rod 1 is fixedly connected to the bottom of the supporting crossbar 2, and a support plate is fixedly connected to the end of the mounting base rod 1. A rotating shaft 13, a rotating shaft 14, and a rotating shaft 15 are rotatably connected to the middle of the support plate. The rotating shaft 15 is fixedly connected to the bottom of the post insulator 6. A limiting piece 5 that mates with the end of the switch 7 is fixedly connected to one end of the switch 4. Grounding rotating rod 19 and grounding rotating rod 29 are rotatably connected to both ends of the supporting crossbar 2. Grounding connecting rods 32 that mate with the grounding rod 8 are fixedly connected to the outer sides of both grounding rotating rod 19 and grounding rotating rod 29. The top of the rotating shaft 13 is fixedly connected to the grounding rod 8. A crank 12 is connected to the top of the crank 12, and a transmission rod 11 is rotatably connected to the top of the transmission rod 11. A connecting rod 10 is rotatably connected to the end of the transmission rod 11. The connecting rod 10 is fixedly connected to the grounding rotating rod 9. It is used to drive the grounding rotating rod 9 to adjust its elevation angle when the shaft 13 rotates horizontally. A crank 12 is fixedly connected to the top of the shaft 14, and a transmission rod 17 is rotatably connected to the top of the crank 12. A connecting rod 18 is rotatably connected to one end of the transmission rod 17. The connecting rod 18 is fixedly connected to the grounding rotating rod 19. It is used to drive the grounding rotating rod 19 to adjust its elevation angle when the shaft 14 rotates horizontally.

[0020] It should be noted that in this embodiment, the rotating shaft 15 drives the rotation of the post insulator 6, and the bottoms of two adjacent post insulators 6 are connected by the transmission rod 33. When one post insulator 6 is driven to rotate, the transmission rod 33 transmits the power to the other post insulators 6, thereby achieving synchronous rotation of multiple post insulators 6. The post insulator 3 located on the same support crossbar 2 is connected diagonally to the bottom of the post insulator 6 by the transmission rod 16. The transmission rod 16 keeps the rotation of post insulator 3 and post insulator 6 linked. This realizes the opening and closing of the switch 4 and the switch 7. One end of the switch 4 is fixed with a limiting piece 5 that cooperates with the end of the switch 7, which is used to limit the switch 7 when it is closed, ensuring reliable closing contact. When adjusting the angle of the grounding rotating rod 19, the rotating shaft 13 moves laterally, and the transmission rod 11 drives the connecting rod 10 to rotate and connect the grounding rotating rod 19. The grounding rotating rod 19 adjusts the grounding connecting rod 32 from inclined to vertical, so that the grounding connecting rod 32 aligns with the grounding rod 8 at the top of the post insulator 3. When adjusting the angle of the grounding rotating rod 29, the rotating shaft 214 rotates horizontally, causing the transmission rod 317 to slide laterally. The transmission rod 317 drives the connecting rod 218 at the bottom of the grounding rotating rod 29 to rotate, and the grounding rotating rod 29 drives the grounding rod 8 on the outside of the grounding connecting rod 32 to align.

[0021] In one embodiment, a transmission box 28 is provided below the mounting base rod 1. Rotating shaft 13, rotating shaft 24 and rotating shaft 35 are all rotatably connected to the transmission box 28. A drive tube 29 is fixedly connected to the middle of rotating shaft 13, rotating shaft 24 and rotating shaft 35. A rotating disk 24 is fixedly connected to the bottom of rotating shaft 13, rotating shaft 24 and rotating shaft 315. Multiple lifting slide rods 25 are vertically slidably connected to the outer side of the rotating disk 24. A spring 26 for driving the lifting slide rod 25 to move downward is sleeved on the outer side of the lifting slide rod 25. Multiple notches that cooperate with the lifting slide rods 25 are opened in the middle of the actuating wheel 23.

[0022] It should be noted that in this embodiment, the metal rod corresponds to the drive tube 29, and the metal rod drives the rotation of rotating shaft 13, rotating shaft 24, or rotating shaft 315 respectively. When the actuating wheel 23 transmits power to the rotating disk 24, the actuating wheel 23 rises and contacts the rotating disk 24, and the actuating wheel 23 presses the lifting slide 25 upward. The lifting slide 25 compresses the second spring. When part of the lifting slide 25 corresponds to the notch of the actuating wheel 23, the lifting slide 25 inserts into the notch. In this way, the rotating disk 24 can be driven to rotate by the actuating wheel 23, and the rotating disk 24 can drive the rotation of rotating shaft 13, rotating shaft 24, or rotating shaft 315. The actuating wheel 23 automatically disengages when it descends.

[0023] In one embodiment, the drive unit includes a linear module 20 fixed inside the transmission box 28, which drives the actuating wheel 23 to correspond to the positions of rotating shaft 13, rotating shaft 24, or rotating shaft 35 respectively. A support frame is fixedly mounted on the moving slide of the linear module 20. A geared motor 21 is fixedly mounted on the outside of the support frame. The geared motor 21 is a servo motor equipped with an encoder. A drive shaft 30 is provided in the middle of the support frame. The linear module 20 is connected to the drive shaft 30 through a spur gear set 22. The drive shaft 30 is vertically slidably connected to one gear of the spur gear set 22. A spring 2 is sleeved on the outside of the drive shaft 30 to drive the actuating wheel 23 to move downward. An electromagnet 31 is fixedly mounted in the middle of the support frame 27. A permanent magnet with the same magnetic poles as the electromagnet 31 is fixedly mounted at the bottom of the drive shaft 30.

[0024] It should be noted that in this embodiment, the linear module 20 drives the support frame 27 to move, so that the actuating wheel 23 corresponds to the position of the rotating disk 24 at the bottom of the rotating shaft 15, preparing to drive the post insulator 6. The electromagnet 31 is energized, pushing the actuating wheel 23 in the middle of the gear to rise. The actuating wheel 23 is equipped with a metal adjustment for guiding its vertical rise and fall, which presses the lifting slide 25 on the rotating disk 24 to cause its compression spring 26 to retract. When the lifting slide 25 aligns with the notch on the actuating wheel 23, the lifting slide 25 springs into the notch under the action of the spring 26, and the actuating wheel 23 and the rotating disk 24 are engaged. The reduction motor 21 starts, driving the drive shaft 30 and the actuating wheel 23 to rotate through the spur gear set 22. The actuating wheel 23 drives the rotating disk 24 to rotate through the lifting slide 25, thereby driving the rotating shaft 15 to rotate horizontally, causing the post insulator 6 fixed to it to rotate counterclockwise around the axis. Because the bottom of post insulator 26 is connected to transmission rod 433, the rotation is transmitted to the adjacent post insulator 26 through transmission rod 433, realizing the synchronous counterclockwise rotation of all post insulator 26. At the same time, because post insulator 13 and post insulator 26 are connected diagonally through transmission rod 216, the counterclockwise rotation of post insulator 26 pulls post insulator 13 through transmission rod 216, causing post insulator 13 to also rotate counterclockwise synchronously, thereby realizing the closing of the circuit. When rotating the grounding rotating rod 9, the linear module 20 drives the actuating wheel 23 to move to correspond with the rotating disk 24 of the rotating shaft 13, and the electromagnet 31 is energized to make the actuating wheel 23 move upward and engage with the rotating disk 24 at the bottom of the rotating shaft 13. The geared motor 21 drives the actuating wheel 23 to rotate, causing the rotating shaft 13 to rotate laterally. The crank 12 then swings, driving the connecting rod 10 via the transmission rod 11, which in turn drives the grounding rotating rod 9 to rotate, adjusting the grounding connecting rod 32 from an inclined state to a vertical state, ensuring precise alignment between the grounding connecting rod 32 and the grounding rod 8 at the top of the post insulator 3. After completion, the electromagnet 31 is de-energized, and the actuating wheel 23 descends and disengages. When the grounding rotating rod 29 is selected, the linear module 20 drives the actuating wheel 23 to move to correspond with the rotating disk 24 of the rotating shaft 24. After the electromagnet 31 is energized and completes the engagement, the geared motor 21 drives the rotating shaft 24 to rotate horizontally. The crank 2 swings, causing the transmission rod 3 17 to slide laterally, driving the grounding rotating rod 29 to rotate via the connecting rod 2 18, ensuring corresponding contact between the grounding rod 8 on the outside of the grounding connecting rod 32. After completion, the electromagnet 31 is de-energized, and the actuating wheel 23 descends and disengages. After the grounding connection rods 32 on both sides come into contact with the corresponding grounding rods 8, the line side voltage is forcibly grounded through the connection between the grounding rods 8 and the fixed grounding structure above, releasing residual charge and providing a safe working environment for maintenance personnel.
