Description

[0001] This invention relates to the field of switchgear testing technology, specifically an intelligent high-voltage switchgear and its testing device. Background Technology

[0002] In power systems, high-voltage switchgear serves as a critical node ensuring the stability and security of power transmission, and its reliability directly impacts the normal operation of the power grid. However, the seismic resistance of traditional high-voltage switchgear often faces severe challenges in the face of sudden natural disasters such as earthquakes. The violent shaking caused by strong earthquakes can easily lead to damage to the internal structure of the equipment and functional failure, resulting in catastrophic power supply interruptions and causing a huge impact on social production order and people's livelihood.

[0003] On the other hand, effective methods for assessing the seismic performance of high-voltage switchgear are currently scarce. The lack of dedicated testing equipment capable of accurately simulating the complex vibration environment of a real earthquake and objectively evaluating the seismic performance of switchgear has become a bottleneck restricting the improvement of equipment safety performance. Therefore, developing intelligent high-voltage switchgear with active seismic resistance capabilities, and developing a high-precision seismic testing system, is of urgent practical need and significant strategic importance for enhancing power grid resilience and ensuring the security of the energy lifeline.

[0032] 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.

[0033] An intelligent high-voltage switchgear and its testing device are disclosed. The intelligent high-voltage switchgear belongs to the field of high-voltage power transmission and distribution equipment technology, while the testing device belongs to the field of power equipment seismic testing equipment technology. This integrated system is specifically designed for the high-reliability operation of key power system equipment under strong seismic conditions. By optimizing the structural design of the switchgear and lowering its center of gravity, its seismic performance is improved. Simultaneously, by equipping it with a dedicated testing device, the amplitude of the switchgear body is adjusted in real time to simulate extreme conditions such as earthquakes, thereby improving testing efficiency.

[0034] A smart high-voltage switchgear, such as Figure 1 and Figure 2 As shown, the switch cabinet includes a main body 1. Inside the main body 1 is an electrical compartment 2 for storing electrical components. A circuit breaker support 3 is installed inside the electrical compartment 2. The circuit breaker support 3 can be raised and lowered along the height of the main body 1. A storage slot 4 is provided at the bottom of the back panel of the main body 1. A conversion mechanism is installed inside the storage slot 4, such as... Figure 3 and Figure 4 As shown, the conversion mechanism is used to release or establish a fixed connection between the circuit breaker base 3 and the switchgear body 1. The conversion mechanism includes a support plate 5 symmetrically hinged inside the receiving groove 4. One end of the support plate 5 extends outside the receiving groove 4 and can abut against the bottom of the circuit breaker base 3. The other end of the support plate 5 has a slot 6. A connecting plate 7 is provided inside the receiving groove 4. The connecting plate 7 can move relative to the support plate 5. A curved locking block 8 is symmetrically provided on the side of the connecting plate 7 adjacent to the support plate 5. The curved locking block 8 can be embedded in the slot 6 to lock the support plate 5. Among them, the connecting plate 7 is symmetrically provided with a first through hole 9. A T-shaped slide rod 10 is inserted into the first through hole 9. The T-shaped slide rod 10... One end is fixedly connected to the inner wall of the storage groove 4. A first spring 11 is sleeved around the T-shaped slide rod 10. The first spring 11 is located between the connecting plate 7 and the inner wall of the storage groove 4. Furthermore, an unlocking component is provided in the storage groove 4 to release the fixed connection between the circuit breaker support 3 and the switch cabinet body 1. The unlocking component includes an electric push rod 12 located in the storage groove 4. The output end of the electric push rod 12 can move in the direction perpendicular to the connecting plate 7. The output end of the electric push rod 12 is rotatably connected to an abutment wheel 13. An unlocking block 14 is provided at the bottom of the connecting plate 7. The unlocking block 14 can roll and contact the abutment wheel 13. The contact surface between the unlocking block 14 and the abutment wheel 13 is curved.

[0035] In use, the vibration sensor inside the electric actuator 12 first detects vibration signals, which triggers the electric actuator 12 to start automatically. When the output end of the electric actuator 12 pushes the contact wheel 13 to roll along the curved surface of the unlocking block 14, it drives the connecting plate 7 to overcome the elastic force of the first spring 11 and move into the receiving groove 4, causing the arc-shaped locking block 8 to disengage from the slot 6. At this time, the support plate 5 is unlocked, and the circuit breaker base 3 slides down along the height direction of the switch cabinet body 1 under its own weight, thereby lowering the center of gravity of the switch cabinet and significantly improving its seismic performance. After the seismic requirement is completed, the staff uses a jack to lift the circuit breaker base 3 to reset it, while manually pulling the support plate 5 to rotate around the hinge axis to reset it. Then, the electric actuator 12 is released, and under the restoring force of the first spring 11, the connecting plate 7 is reset, the arc-shaped locking block 8 is re-embedded into the slot 6, and the support plate 5 is locked again, thus firmly supporting the circuit breaker base 3 in the switch cabinet body 1.

[0036] like Figure 1 and Figure 5 As shown, the intelligent high-voltage switchgear of the present invention also includes a buffer assembly. The buffer assembly includes a transmission arm 15 hinged to the bottom of the electrical compartment 2 and a follower slide rail 16 arranged symmetrically and parallel to the bottom of the circuit breaker base 3 along the length direction of the circuit breaker base 3. A follower slider 17 is slidably arranged in the follower slide rail 16. One end of the transmission arm 15 away from the bottom of the electrical compartment 2 is hinged to the follower slider 17. A spring 18 is arranged between the transmission arm 15 and the bottom of the electrical compartment 2.

[0037] When in use, when the circuit breaker base 3 is raised or lowered, the transmission arm 15 will swing around the hinge point and drive the follower slider 17 to slide in the follower slide rail 16. At the same time, the compression spring 18 will produce elastic deformation, which effectively buffers the movement impact of the circuit breaker base 3, reduces the impact intensity on the internal electrical components of the switch cabinet body 1, and ensures the structural stability of the switch cabinet body 1.

[0038] A testing device, such as Figure 6 and Figure 7 As shown, the system includes a vibration table, which comprises a frame 19, a support platform 20 suspended above the frame 19, and a vibration assembly disposed between the frame 19 and the support platform 20; as shown Figure 7 and Figure 8As shown, the vibration assembly includes a rotating disk 21 movably mounted on a platform 19 and a linear slide rail 22 mounted on the bottom of a support platform 20. A ball joint rod 23 is eccentrically hinged to the top of the rotating disk 21, and an adjusting slider 24 is ball-jointed to the top of the ball joint rod 23. The adjusting slider 24 slides in cooperation with the linear slide rail 22. A vertical plate 25 is fixedly connected to the platform 19, and support rods 26, parallel to the support platform 20, are symmetrically fixedly connected to the vertical plate 25. A second through hole 27 is formed on the surface of the support rod 26. A guide post 28 is provided at the bottom of the support platform 20, with its bottom end penetrating the second through hole 27. A second spring 29 is provided between the support platform 20 and the support rod 26. Furthermore, a device cavity 30 is provided at the bottom of the platform 19. Figure 6 and Figure 7 As shown, a first motor 31 is installed inside the equipment cavity 30. The output end of the first motor 31 is connected to a reducer 32, and the output end of the reducer 32 is coaxially fixed to the rotating disk 21. Furthermore, an adjustment assembly is installed inside the linear slide rail 22, which is used to adjust the relative position of the adjusting slider 24 on the linear slide rail 22. Figure 8 As shown, the adjustment assembly includes an adjustment groove 33 opened along the track travel direction of the linear slide rail 22, an adjustment screw 34 is rotatably connected inside the adjustment groove 33, a second motor 35 is fixedly connected to one end of the linear slide rail 22, the output end of the second motor 35 is fixedly connected to the adjustment screw 34, and a movable slider 36 is fixedly connected to the adjustment slider 24 and threadedly connected to the adjustment screw 34.

[0039] In operation, the first motor 31 is started first, and after being reduced in speed by the reducer 32, it drives the rotating disk 21 to rotate. The use of the reducer 32 not only reduces the rotational speed of the rotating disk 21, but also significantly increases the torque, ensuring that the rotating disk 21 can stably and powerfully drive the ball head rod 23 to rotate eccentrically. The eccentric rotation of the ball head rod 23 pushes the adjusting slider 24 to slide back and forth along the linear slide rail 22. Since the adjusting slider 24 is connected to the bottom of the support platform 20, its motion is converted into the vertical vibration of the support platform 20, thereby simulating the up and down shaking during an earthquake. At the same time, the second motor 35 drives the adjusting screw 34 to rotate, and through the threaded transmission, the moving slider 36 drives the adjusting slider 24 to move on the linear slide rail 22, thereby changing the eccentricity of the ball head rod 23, and thus adjusting the amplitude of the vibration to meet the needs of earthquake simulation of different intensities. The support rod 26 and the second spring 29 on the vertical plate 25 play an auxiliary support and buffering role to ensure the stable operation of the vibration table.

[0040] like Figure 6 and Figure 9As shown, the vibration assembly also includes symmetrically fixed transverse slide rails 37 on the top of the support platform 20. A transverse slider 38 is slidably connected to the top of the transverse slide rail 37, and a transverse slide table 39 is fixedly connected to the top of the two transverse sliders 38. A guide slide rail 40 is obliquely fixedly installed on the side of the upright plate 25 near the transverse slide table 39. A roller 41 is rotatably installed inside the guide slide rail 40, and the roller 41 is rotatably connected to the transverse slide table 39. A locking assembly for fixing the switch cabinet body 1 is provided on the transverse slide table 39, such as... Figure 9 and Figure 10 As shown, the locking assembly includes a pair of component slots 42 on the top of the transverse slide 39. An L-shaped locking plate 43 is hinged inside the component slot 42. A locking worm gear 44 is fixedly connected to the hinged end of the L-shaped locking plate 43. A locking worm 45 that meshes with the locking worm gear 44 is rotatably connected inside the component slot 42. A locking lever 46 is rotatably connected to the bottom of the transverse slide 39. A pair of bevel gears 47 are fixedly connected to one end of the locking lever 46. A bevel gear 48 that meshes with the bevel gears 47 is fixedly connected to one end of the locking worm 45. The transmission assembly is prior art. When in use, the locking lever 46 is rotated. Under the drive of the transmission assembly, multiple L-shaped locking plates 43 can be controlled to lock the switch cabinet body 1 simultaneously.

[0041] In use, the switch cabinet body 1 is first fixed on the transverse slide 39. By operating the locking lever 46 to rotate, the locking lever 46 drives the first bevel gear 47 to rotate. The first bevel gear 47 meshes with the second bevel gear 48, thereby driving the locking worm gear 45 to rotate. The rotation of the locking worm gear 45 further drives the locking worm wheel 44 to rotate. The rotation of the locking worm wheel 44 causes the L-shaped locking plate 43 to rotate around its hinge point and form a firm lock on the switch cabinet body 1. Then, the setting of the transverse slide rail 37 and the transverse slider 38 allows the transverse slide 39 together with the switch cabinet body 1 on it to move within a certain range in the horizontal direction, further simulating the horizontal swaying situation that may occur during an earthquake. The guide rail 40 and the roller 41 provide guidance for the horizontal movement of the transverse slide 39, ensuring the accuracy and reliability of the test process.

[0042] The working principle of the intelligent high-voltage switchgear and its testing device provided by this invention is as follows:

[0043] First, the switch cabinet body 1 is fixed on the transverse slide table 39. By rotating the locking lever 46, the locking lever 46 drives the first bevel gear 47 to rotate. The first bevel gear 47 meshes with the second bevel gear 48, thereby driving the locking worm gear 45 to rotate. The rotation of the locking worm gear 45 further drives the locking worm wheel 44 to rotate. The rotation of the locking worm wheel 44 causes the L-shaped locking plate 43 to rotate around its hinge point, thus forming a firm lock on the switch cabinet body 1. Then, the first motor 31 is started, and after being reduced in speed by the reducer 32, it drives the rotating disk 21 to rotate. The use of the reducer 32 not only reduces the rotational speed of the rotating disk 21, but also significantly increases the torque, ensuring that the rotating disk 21 can rotate stably and powerfully. The ball joint 23 is driven to rotate eccentrically. This eccentric rotation of the ball joint 23 pushes the adjusting slider 24 to slide back and forth along the linear slide rail 22. Since the adjusting slider 24 is connected to the bottom of the support platform 20, its motion is converted into the vertical vibration of the support platform 20, thus simulating the up-and-down shaking during an earthquake. At the same time, the second motor 35 drives the adjusting screw 34 to rotate, which, through the screw drive, causes the moving slider 36 to move the adjusting slider 24 on the linear slide rail 22, thereby changing the eccentricity of the ball joint 23 and thus adjusting the amplitude of the vibration to meet the needs of earthquake simulation of different intensities. The support rod 26 and the second spring 29 on the vertical plate 25 play an auxiliary support and buffering role. This ensures the stable operation of the vibration table. Furthermore, the horizontal sliding rail 37 and horizontal sliding block 38 allow the horizontal sliding table 39, along with the switch cabinet body 1 on it, to move within a certain range in the horizontal direction, further simulating the horizontal swaying that may occur during an earthquake. The guide rail 40 and roller 41 provide guidance for the horizontal movement of the horizontal sliding table 39, ensuring the accuracy and reliability of the testing process. Then, when the switch cabinet body 1 transmits vibration to the electric actuator 12, the vibration sensor inside the electric actuator 12 automatically detects the vibration signal, triggering the electric actuator 12 to start automatically. The output end of the electric actuator 12 pushes the contact wheel 13 to roll along the curved surface of the unlocking block 14. The connecting plate 7 moves into the receiving groove 4 against the elastic force of the first spring 11, causing the arc-shaped locking block 8 to disengage from the slot 6. At this time, the support plate 5 is unlocked, and the circuit breaker base 3 slides down along the height direction of the switch cabinet body 1 under its own weight, thereby lowering the center of gravity of the switch cabinet and significantly improving its seismic performance. When the circuit breaker base 3 is raised and lowered, the transmission arm 15 swings around the hinge point and drives the follower slider 17 to slide in the follower slide rail 16. At the same time, the second spring 18 is squeezed to produce elastic deformation, which effectively buffers the movement impact of the circuit breaker base 3, reduces the impact intensity on the internal electrical components of the switch cabinet body 1, and ensures the structural stability of the switch cabinet body 1.Finally, after the seismic test, the staff used jacks to lift the circuit breaker base 3 for repositioning, while manually pulling the support plate 5 to rotate around the hinge axis for repositioning. Then, the electric push rod 12 was released, and under the restoring force of the first spring 11, the connecting plate 7 was reset, the arc-shaped locking block 8 re-embedded into the slot 6, and the support plate 5 was locked again, thus firmly supporting the circuit breaker base 3 within the switchgear body 1.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
