Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear technology, and in particular to a high-reliability high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is a core piece of equipment in the field of smart grid power transmission and distribution. Relying on power electronic components such as metal-oxide-semiconductor field-effect transistors (MOSFETs), insulated-gate bipolar transistors (IGBTs), and modules, it is widely used in power supply scenarios such as 750 kV and above AC transmission, large-scale power grid security and defense systems, and intelligent dispatching systems. It plays a role in circuit control, protection, and component storage. Existing conventional products have simple structures, with internal components mostly fixed by bolts and simple clips. They lack multi-level adjustment structures, making it difficult to adapt to different specifications of components and resulting in poor versatility. Their internal support frame is a fixed design, making it difficult to remove the entire unit when components fail or lines malfunction. Workers can only perform maintenance in a small cabinet, which not only leads to low work efficiency but also poses safety hazards and is difficult to meet the requirements of efficient operation and maintenance of power equipment.

[0003] In the existing technology, most switch cabinets do not have integrated monitoring devices and mainly rely on manual inspection. It is difficult to monitor the operating status of components in real time, and there is a lag in fault detection. Potential problems such as component overload and overheating are difficult to be investigated in time, which can easily lead to tripping, equipment damage, or even power outages, affecting power supply stability. At the same time, the cabinet ventilation layout is unreasonable and the heat dissipation effect is poor. Components will age faster and shorten their service life when they are in a high-temperature environment for a long time, which will also increase the cost of subsequent maintenance and parts replacement.

[0004] Traditional high-voltage switchgear has an imperfect design for its support and movement mechanisms. The slide rails lack limit, guide, and linkage unlocking structures, making it easy for components to shift or get stuck. Positioning and locking are unreliable, and components are prone to loosening and displacement. Its clamping and adjustment mechanisms are independent of each other, making operation cumbersome and positioning accuracy poor. Hard clamping parts can also easily damage electronic components. Overall, there are many problems in component fixing, adjustment, operation and maintenance, and structural linkage, making it difficult to meet the high-load and high-reliability requirements of modern power equipment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a high-reliability high-voltage switchgear to address the numerous defects of existing high-voltage switchgear, which are widely used but have the following drawbacks: simple component fixing structure, inability to be moved out for maintenance as a whole; lack of real-time monitoring function, delayed fault detection, poor heat dissipation; unreasonable design of moving and clamping mechanisms, easy jamming and damage to components, making it difficult to meet the high-reliability operation requirements of modern power equipment.

[0015] Optionally, a sliding column is installed inside the annular groove via a bearing. An annular buckle is installed on one side of the sliding column. A semi-circular groove is opened on one side of the annular buckle. Multiple sets of semi-circular gaskets are installed on the inner wall of the semi-circular groove. The semi-circular gaskets are made of rubber.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, the internal components have complete adjustment functions, enabling them to adapt to various types of electronic components for fastening operations. This effectively improves the equipment's versatility and adaptability. The equipment integrates a multi-level adjustable structure, allowing for flexible adjustment of the overall support structure's position. Combined with a horizontal adjustment mechanism, the placement of the clamping parts can be changed. At the same time, the angle and opening / closing range of the clamping components can be precisely controlled. Workers can freely adjust the support and clamping points according to the external dimensions and actual installation location of the electronic components, ensuring that the clamping structure precisely fits the component surface for a secure fixation. Compared to the single fixing method of traditional switchgear, this solution overcomes structural limitations, is compatible with electronic components of different specifications and shapes, offers flexible and diverse fixing methods, and provides stable and reliable fastening effects. It can meet the assembly and use requirements under different working conditions, significantly expanding the equipment's application range.

[0018] The novel structural design of the adjustment components and the excellent linkage between various functional parts ensure smooth transmission and effectively improve adjustment accuracy and ease of use. The entire adjustment mechanism forms an integrated transmission system, allowing rotational operations to be synchronously converted into linear displacement for position adjustment. Simultaneously, the adjustment mechanism and clamping mechanism work together to form a self-locking structure after adjustment, preventing position deviation. The clamping part uses a gear and thread transmission method, coupled with a damping structure to stabilize the adjustment angle. All action links are tightly connected, ensuring smooth and stable operation without jamming or deviation. Traditional equipment has independent adjustment and clamping mechanisms, resulting in cumbersome operation steps and significant positioning errors. This solution, relying on a highly interconnected integrated structure, simplifies the operation process, improves positioning accuracy, and significantly enhances the overall stability and reliability of the mechanical operation.

[0019] When the equipment detects a malfunction in an electronic component and requires maintenance, the entire support frame can be moved out in a coordinated manner, greatly optimizing maintenance conditions. The equipment is equipped with a status detection component that can monitor the operating status of electronic components in real time. Once an abnormal signal is detected, the power mechanism is automatically activated, driving the entire support frame to move outward. During the frame movement, the limit structure can be automatically unlocked, and all support components, adjustment mechanisms, and clamping mechanisms maintain their relative positions. The components are always firmly clamped, preventing loosening or collisions. The entire removal process is completed automatically without the need for manual disassembly of internal components. The components, along with the functional frame, can be moved out of the cabinet as a whole, allowing staff to carry out maintenance and replacement operations in an open space. This solves the problems of limited space, high maintenance difficulty, and high safety risks associated with traditional switchgear, effectively improving maintenance efficiency, shortening equipment downtime, and ensuring the continuous and stable operation of the power system.

[0033] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0034] like Figures 1 to 11As shown, an embodiment of the present invention provides a high-reliability high-voltage switchgear, including a switchgear device 1. A switchgear housing 10 is installed outside the switchgear device 1. Two sets of partitions 11 are installed on one inner wall of the switchgear housing 10. A first groove 12 is formed on the bottom inner wall of the switchgear housing 10, and a second groove 13 is formed at the bottom of the first groove 12. L-shaped buckles 14 are installed on both sides of the second groove 13 via damping connections. A ventilation opening 15 is formed on one side of the switchgear housing 10. A telescopic assembly 2 is installed on one inner wall of the switchgear housing 10, and an adjusting assembly 3 is installed on the telescopic assembly 2. A clamping assembly 4 is installed inside the adjusting assembly 3. A sensor 16 is installed on the top inner wall of the switchgear housing 10, and a base 17 is installed on the top inner wall of the switchgear housing 10. A slide rail 18 is installed on the top inner wall of the switchgear housing 10, with both ends of the slide rail 18 installed on one side of the base 17. The partitions 11 divide the interior of the switchgear housing 10 into independent functional areas, which can avoid mutual interference between electronic components in different areas and simultaneously improve the efficiency of the cabinet interior. To maximize space utilization, the ventilation opening 15 adopts an open layout, enabling continuous air convection between the inside and outside of the cabinet and promptly removing the heat generated by the components. The sensor 16 is fixed at a high position on the top of the cabinet, providing an unobstructed monitoring view and allowing for comprehensive collection of the operating parameters of the components inside the cabinet. The base 17 and the slide rail 18 combine to form a stable support and guiding system, providing a straight running trajectory for the movement of the L-shaped support rod 22. The electric cylinder 20 serves as a power source, driving the first connecting rod 200 and the telescopic frame 21 to move linearly along the third groove 210 and the fourth groove 221, respectively, with tight transmission and engagement. The L-shaped support rod 22 is assembled and connected to the first support rod 23 and the second support rod 24 through the first hole 220 and the second hole 230. The overall support frame is easy to assemble and structurally stable. The first sliding box 25 and the sliding rod 26 form a sliding pair, and the sliding wheel 29 mounted on the second connecting rod 28 runs in contact with the fifth groove 27, the first groove 12, and the second groove 13, respectively, significantly reducing the frictional resistance during the overall frame displacement process.

[0035] like Figures 3 to 7As shown, the telescopic assembly 2 includes an electric cylinder 20, which is installed on the inner wall of one side of the switch cabinet housing 10. A first connecting rod 200 is installed at the output end of the electric cylinder 20. A telescopic frame 21 is installed at one end of the first connecting rod 200 via a bearing. A third groove 210 is formed on the inner wall of one side of the switch cabinet housing 10. One end of the telescopic frame 21 is tightly fitted inside the third groove 210, and an L-shaped support rod 22 is tightly fitted at the other end of the telescopic frame 21. The L-shaped support rod 22 is installed at the bottom of the slide rail 18 and on the bottom inner wall of the switch cabinet housing 10. A fourth groove 221 is formed on one side of the L-shaped support rod 22. One end is tightly fitted inside the fourth groove 221. A first hole 220 is formed on one side of the L-shaped support rod 22. A first support rod 23 is bolted to the inner wall of the first hole 220. A second hole 230 is formed on one side of the first support rod 23. A second support rod 24 is bolted to the inner wall of the second hole 230. A first sliding box 25 is sleeved on the outer surface of the L-shaped support rod 22. A sliding rod 26 is nested inside the first sliding box 25. Both ends of the sliding rod 26 are mounted on one side of the base 17. A fifth groove 27 is formed at the bottom of the L-shaped support rod 22. A second connecting rod 28 is installed at the bottom of the L-shaped support rod 22. A bearing is mounted on one side of the second connecting rod 28. The sliding wheel 29 has one side tightly fitted inside the fifth groove 27 and the other side tightly fitted inside the first groove 12. The sensor 16 has a real-time signal feedback function. Once it detects abnormal data such as current, temperature, or vibration, it can immediately send a start command to the electric cylinder 20. The response speed is fast, and the electric cylinder 20 outputs a uniform and stable thrust, driving the first connecting rod 200 and the telescopic frame 21 to slide at a uniform speed in the corresponding groove. The transmission action is smooth and shock-free. The L-shaped support rod 22, the first support rod 23, and the second support rod 24 form an integrated support frame with high overall rigidity. No deformation will occur during displacement. The first sliding box 25... The sliding rod 26 slides in a directional manner, effectively constraining the swing amplitude of the frame. When the sliding wheel 29 rolls forward, it uses the wheel structure to push the L-shaped buckle 14, and completes the limit unlocking by mechanical linkage. No manual intervention is required, and the degree of automation is high. The damping structure of the L-shaped buckle 14 can achieve repeated opening and closing and has a long service life. The second support rod 24 drives the second sliding box 30 to move horizontally as a whole. All components inside the adjustment component 3 remain relatively stationary, and the original adjustment parameters and positioning state are completely preserved. The clamping component 4 moves synchronously with the frame, and the clamping posture remains unchanged. The electronic components are firmly bound throughout the process, effectively preventing problems such as loosening and collision damage during the movement.

[0036] like Figure 8 , Figure 9As shown, the adjusting assembly 3 includes a second sliding box 30, which is mounted on the outer surface of the second support rod 24. A circular groove 31 is formed on one side of the second sliding box 30. A telescopic rod 32 is mounted inside the circular groove 31 via a bearing. A handle 33 is mounted on one end of the telescopic rod 32. A first screw 34 is mounted on one side of the handle 33. A first external thread 35 is mounted on the outer surface of the first screw 34. A first internal thread 36 is engaged with the outer surface of the first external thread 35. The first internal thread 36 is installed inside the second sliding box 30. A first turntable 37 is sleeved on the outer surface of one end of the first screw 34. One side of the first turntable 37 is frosted and fitted with a semi-circular rubber pad. The second sliding box 30 has a third hole 38 inside, and the outer surface of the second support rod 24 passes through the third hole 38. The circular groove 31 forms a radial limit on the telescopic rod 32 to ensure coaxiality during rotation. The first screw 34, the first external thread 35 and the first internal thread 36 form a thread transmission mechanism to convert the rotational motion into linear displacement of the second sliding box 30. The third hole 38 and the second support rod 24 are precisely matched to limit the movement direction of the second sliding box 30. The surface of the first turntable 37 is provided with an anti-slip structure and a rubber pad, which makes it less likely to slip during rotation. At the same time, it can form a friction lock with the gear structure, providing double protection to ensure that the adjustment position will not be offset, and further enhancing the stability of component clamping.

[0037] like Figures 9 to 11As shown, the clamping assembly 4 includes a sixth groove 40, which is located at the top of the second sliding box 30. A first gear 41 is mounted on one side of the inner wall of the sixth groove 40 via a bearing. A second gear 42 is meshed with one side of the first gear 41. A second turntable 43 is mounted on the second gear 42 via a rotating rod and a bearing. The rotating rod and bearing are dampedly connected to the sixth groove 40. An arc-shaped rotating plate 44 is mounted on one side of the second turntable 43. A second internal thread 440 is installed inside the arc-shaped rotating plate 44. The second internal thread 440 meshes with a second external thread 441. A second screw 442 is sleeved at the center of the second external thread 441. An annular groove 45 is provided at one end of the arc-shaped rotating plate 44. A sliding column 46 is mounted inside the annular groove 45 via a bearing. An annular buckle 47 is installed on one side of the sliding column 46. A semi-circular groove 48 is provided on one side of the annular buckle 47. Multiple sets of semicircular gaskets 49 are installed on the inner wall of the semicircular groove 48. The semicircular gaskets 49 are made of rubber. The sixth groove 40 provides a stable installation space for the first gear 41 and the second gear 42. The two sets of gears mesh with each other, and the power transmission is smooth and uniform. The second turntable 43 adopts a damping connection structure with the mounting base, which can achieve initial self-locking of angle positioning and avoid deflection due to external forces. The arc-shaped rotating plate 44 completes the attitude fine adjustment by relying on the thread pair composed of the second internal thread 440, the second external thread 441, and the second screw 442. The adjustment accuracy is high and the operation is simple. The annular groove 45 reserves the movement space for the sliding column 46, so that the annular buckle 47 can flexibly adapt to the shape of the component. The semicircular groove 48 is equipped with semicircular gaskets 49 made of rubber, which can increase the contact friction and buffer the clamping pressure, and prevent hard structures from scratching the surface of electronic components.

[0038] The working principle of the technical solution provided by this invention is as follows:

[0039] First, when all components inside the switch cabinet device 1 are in their initial positions, the partition 11 is fixed to the inner wall of one side of the switch cabinet housing 10, dividing the cabinet space. The first groove 12 and the second groove 13, together with the L-shaped buckle 14, limit the bottom sliding wheel 29. The ventilation vent 15 continuously ensures air circulation inside the cabinet. The sensor 16 collects the operating data inside the cabinet in real time. The base 17 and the slide rail 18 provide support and guidance for the L-shaped support rod 22. The operator adjusts the electric pneumatic mechanism in real time according to the position of the electronic components inside the cabinet. The cylinder 20 drives the telescopic frame 21 to move. The first connecting rod 200 and the telescopic frame 21 slide within the third groove 210 and the fourth groove 221, driving the L-shaped support rod 22 to complete the position adjustment. The L-shaped support rod 22, in conjunction with the first hole 220, the first support rod 23, the second hole 230, and the second support rod 24, completes the positioning of the support system. The first sliding box 25 and the sliding rod 26 then match their positions. The second connecting rod 28 and the sliding wheel 29 move along the fifth groove 27, the first groove 12, and the second groove 13.

[0040] Subsequently, the operator needs to simultaneously adjust the positions of the clamping assembly 4 and the second sliding box 30. Under the action of the damping connection, the first gear 41 and the second gear 42 meshing with each other in the sixth groove 40 rotate, synchronously driving the second turntable 43 to rotate. The rotation of the second turntable 43 drives the arc-shaped rotating plate 44 to swing, rotating the second screw 442. By using the cooperation of the second external thread 441 and the second internal thread 440, the angle of the arc-shaped rotating plate 44 is finely adjusted. The sliding column 46 moves in the annular groove 45, driving the annular buckle 47 to approach the electronic component. With the help of the semi-circular groove 48 and the semi-circular washer 49, clamping is completed. Then, the operator turns the handle 33 to drive the telescopic rod 32 and the first screw 34 inside the circular groove 31 to rotate, relying on... The first external thread 35 and the first internal thread 36 mesh and drive, causing the second sliding box 30 to slide and be secured along the second support rod 24 through the third hole 38, completing the horizontal position calibration of the adjustment component 3. At the same time, the rotation of the handle 33 causes the first turntable 37 located at the end of the first screw 34 to rotate and move forward, rubbing against and securing with the first gear 41, completing all adjustment and clamping work. After the debugging is completed, the electric cylinder 20 stops, and the entire set of telescopic component 2, adjustment component 3, and clamping component 4 stays in the position after adjustment. The ventilation port 15 continuously enables air circulation in the cabinet, and the sensor 16 continuously monitors the operating status of the electronic components. All components work together to complete the electronic component fixing work at the initial work position for a long time.

[0041] Secondly, when sensor 16 detects an abnormality in the operation of the compressed electronic component, the equipment automatically initiates the emergency removal process. After sensor 16 sends a signal, electric cylinder 20 immediately starts and outputs linear power, pushing the first connecting rod 200 to move linearly. The first connecting rod 200 drives the telescopic frame 21 to slide inside the third groove 210 and the fourth groove 221, thereby pulling the L-shaped support rod 22 to begin overall displacement. L-shaped support rod 22 moves outward in sync with first support rod 23 and second support rod 24. First sliding box 25 slides along sliding rod 26 following L-shaped support rod 22. Second connecting rod 28 drives sliding wheel 29 to roll in fifth groove 27, first groove 12 and second groove 13. When sliding wheel 29 rolls, it will automatically press down L-shaped buckle 14 and automatically unlock the cabinet door. L-shaped buckle 14 releases its damping limit, providing passage space for sliding wheel 29 to move. Second support rod 24 drives adjustment component 3 to move horizontally as a whole. The internal structure of second sliding box 30 remains relatively fixed and no longer performs position adjustment operation. Second sliding box 30 drives clamping component 4 to move together to maintain the original clamping state. The entire frame gradually moves to the outside of switch cabinet shell 10. Switch cabinet device 1, switch cabinet shell 10, partition 11 and ventilation opening 15 remain stationary.
