Description

Technical Field

[0001] This invention belongs to the technical field of gas-filled switchgear for ultra-high voltage power transmission, specifically relating to gas-filled switchgear for ultra-high voltage power transmission based on an intelligent monitoring system. Background Technology

[0002] Intelligent monitoring systems play a central role in modern power equipment (such as GIS, circuit breakers, etc.), enabling real-time perception of equipment status and predictive maintenance through multi-dimensional sensing, edge computing, and AI diagnostics.

[0003] Gas-insulated switchgear for ultra-high voltage transmission (usually referring to gas-insulated switchgear with voltage levels of 72.5kV and above) is the core equipment for achieving high-reliability power transmission in power systems. Its core design is to seal high-voltage live components (such as circuit breakers, disconnectors, busbars, etc.) in a metal shell filled with insulating gas. By replacing traditional air insulation with gas insulation, the environmental adaptability, safety and compactness of the equipment are significantly improved.

[0004] Publication number "CN116131150B" describes "an inflatable multi-functional PT cabinet, belonging to the field of inflatable cabinet technology, including a cabinet cable device. A PT chamber is located at the bottom of the cabinet. An inflation chamber and a power chamber are arranged side-by-side on the upper side of the PT chamber. A switching device is sealed and fixedly installed inside the inflation chamber, and a power device is fixedly installed inside the power chamber. A first terminal block is sealed and fixedly installed on the top of the inflation chamber, and the first terminal block is electrically connected to the switching device. A second terminal block is sealed and fixedly installed on the partition between the inflation chamber and the PT chamber, and the second terminal block is electrically connected to the switching device. The lower end of the second terminal block is electrically connected to a third terminal block on the PT device via a cable device. A grounding wire device is installed on the cable device. The PT device is installed in the PT chamber to detect the voltage of high-voltage transmission and simultaneously convert part of the voltage for use by the cabinet, effectively meeting the cabinet's requirements."

[0005] The aforementioned patent describes a PT device for high-voltage power transmission voltage detection, simultaneously converting a portion of the voltage for use within the cabinet, effectively meeting the cabinet's requirements. The opening / closing device and the PT device are connected via a cable assembly. Both ends of the cable assembly are detachable for easy installation and replacement. The cable assembly incorporates a hollow conductive tube; during assembly, dry insulating gas is injected through this tube to effectively expel air from the device, enhancing its installation performance. Furthermore, the cable assembly features a winding layer, inner insulation layer, metal shielding layer, outer insulation layer, high-temperature fire-resistant layer, outer protective layer, and a sealed winding coil assembly, further strengthening its insulation, fire resistance, and moisture resistance. The grounding wire prevents leakage, ensuring the cable assembly remains safe to touch during power transmission. The sliding sealing assembly consists of a fixed sleeve, a heat insulation ring, a first elastic sealing ring, a sealing ring pressure pad, a clamping ring, and a clamping adjustment component. The clamping adjustment component adjusts the clamping ring's force, allowing the first elastic sealing ring to achieve a better seal. The sealing ring pressure pad then separates the first elastic sealing ring, achieving a multiple sealing effect and ensuring the inflation chamber does not leak. The rotating sealing assembly consists of a rotating sealing ball, a rotating sealing bowl, a clamping bowl, and a second elastic sealing ring. This arrangement allows for sealing on multiple surfaces, ensuring a better sealing effect. While surge arresters can eliminate overvoltage in PT cabinets, during routine maintenance of UHV transmission gas-filled switchgear, the concentration of electrical components within the inflation chamber makes fault diagnosis and prediction impossible. Therefore, we propose an UHV transmission gas-filled switchgear based on an intelligent monitoring system. Summary of the Invention

[0006] The purpose of this invention is to provide an ultra-high voltage power transmission gas-filled switchgear based on an intelligent monitoring system. The system involves installing an adjustable infrared camera inside the gas-filled chamber to periodically inspect various electrical components, monitor their contacts and abnormal temperature rise points in real time, and collect abnormal temperature data from these points. This data forms fault temperature data for the electrical components, which is then input into a fault database to simulate operation. This allows for early fault diagnosis and prediction of electrical components within the gas-filled chamber, thus preventing potential faults and efficiently maintaining the safe operation of the ultra-high voltage power transmission gas-filled switchgear.

Sealing strips are fixedly connected to the inner walls of the two cabinet doors, and the two sealing strips correspond to the two door slots.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this solution, during the linear movement of the infrared camera, the lead screw rotates. The lead screw, through its sliding engagement with the slider, pushes the slider to reciprocate linearly within the cabinet. The slider drives the rotating shaft to move, which in turn drives the mounting bracket to move between the inner walls of the cabinet. The mounting bracket drives the infrared camera, causing the infrared camera to reciprocate linearly within the cabinet. The infrared camera performs infrared scanning of the electronic components within the cabinet through this reciprocating movement. This allows the infrared camera to periodically inspect various electrical components, monitor their contacts and identify any abnormal temperature rise points in real time, and collect abnormal temperature data from these points. This data forms the fault temperature data of the electrical components and is input into a fault database for simulated operation. This allows for early fault diagnosis and prediction of the electrical components within the gas filling chamber, enabling the early elimination of faults and efficiently maintaining the safe operation of the gas-filled switchgear for ultra-high voltage power transmission.

[0024] 2. In this solution, when the infrared camera scanning end is tilted at an angle, the pawl releases its engagement with the ratchet, and the second motor is started by power. The output end of the second motor drives the push-pull rod to deflect. The push-pull rod, through its rotational connection with the swing rod, drives the swing rod to deflect. The swing rod drives the rotating shaft to deflect, and the rotating shaft drives the mounting bracket to deflect. This causes the mounting bracket to tilt the infrared camera at an angle, allowing the infrared camera to expand its scanning angle through tilting. This facilitates a wide range of infrared fault diagnosis of the built-in electrical components in the gas-filled cabinet for ultra-high voltage power transmission based on the intelligent monitoring system.

[0025] 3. In this solution, when the infrared camera is tilted, the output end of the electric push rod extends to push the pawl away from the ratchet, thus releasing the pawl from the ratchet and facilitating the rotation of the ratchet and the shaft. When it is necessary to lock the tilt angle of the infrared camera, the output end of the electric push rod extends to push the pawl into engagement with the ratchet, thereby locking the rotation of the ratchet and subsequently locking the rotation of the shaft. This locks the mounting bracket and the infrared camera at the tilt angle, enabling the infrared camera to perform point scanning of the flammable points of different electrical components through deflection and linear movement. This allows the gas-filled switchgear for ultra-high voltage power transmission based on the intelligent monitoring system to perform point scanning of the flammable points of electrical components.

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.

[0039] Example 1

[0040] Reference Figures 1-10 Gas-filled switchgear for ultra-high voltage power transmission based on an intelligent monitoring system includes:

[0041] Cabinet 1;

[0042] Mounting bracket 19 is disposed between the inner walls of cabinet 1, and an infrared camera 20 is fixedly mounted on the side end of mounting bracket 19; and

[0043] An adjustment mechanism is installed between the inner walls of the cabinet 1 and is connected to the mounting bracket 19 to move the infrared camera 20.

[0044] In this invention, the cabinet 1 is used to house the mounting frame 19, the infrared camera 20, and the adjustment mechanism. The mounting frame 19 is used to support and fix the infrared camera 20, and the adjustment mechanism is connected to the mounting frame 19 to move the infrared camera 20.

[0045] The adjustment mechanism includes a drive assembly, a push assembly, a linkage assembly, a limit assembly, a positioning assembly, and a rewind assembly. The push assembly is located between the inner walls of the cabinet 1 and is situated on the upper side of the mounting bracket 19. The drive assembly is located on the inner wall of the cabinet 1 and is connected to the push assembly. The linkage assembly is located at the bottom of the push assembly and is connected to the mounting bracket 19. The limit assembly is located on one side of the mounting bracket 19 and is connected to the linkage assembly. The positioning assembly is located between the inner walls of the cabinet 1 and is connected to the push assembly. The rewind assembly is located between the inner walls of the cabinet 1 and is connected to the infrared camera 20.

[0046] In this invention, the pushing component is used to move the infrared camera 20 horizontally in a straight line, the driving component is used to provide power for the movement of the infrared camera 20, the linkage component is used to deflect the infrared camera 20 up and down, the limiting component is used to limit the deflection angle of the infrared camera 20, the positioning component is used to monitor the movement of the infrared camera 20, and the winding component is used to wind and wrap the winding line 24.

[0047] The pushing assembly includes a guide post 7, a lead screw 8, and a slider 9. The guide post 7 is rotatably connected between the inner walls of the cabinet 1 and is located on the upper side of the mounting bracket 19. The lead screw 8 is fixedly connected between the inner walls of the cabinet 1 and is located on the side end of the guide post 7. The slider 9 is sleeved on the circumferential surface of the guide post 7 and the lead screw 8 and is located on the side end of the mounting bracket 19.

[0048] In this invention, the guide post 7 is used to assist and support the movement of the slider 9. The lead screw 8, through its sliding engagement with the slider 9, pushes the slider 9 to move horizontally in a straight line. The slider 9 is used to support and fix the second motor 21, the ratchet cover 14, and the infrared laser emitter 33. During the linear movement of the infrared camera 20, the lead screw 8 rotates, and through its sliding engagement with the slider 9, the lead screw 8 pushes the slider 9 to reciprocate linearly within the cabinet 1. The slider 9 drives the rotating shaft 18 to move, and the rotating shaft 18 drives the mounting bracket 19 to move between the inner walls of the cabinet 1. The mounting bracket 19 drives the infrared camera 20, thereby enabling the infrared camera to... The head 20 moves back and forth in a straight line within the cabinet 1. The infrared camera 20 scans the electronic components inside the cabinet 1 with infrared light through this reciprocating movement. This allows the infrared camera 20 to perform regular inspections of various electrical components, real-time inspections of electrical component contacts and various abnormal temperature rise points, and simultaneously collects abnormal temperature data from these abnormal temperature rise points. This data forms fault temperature data for the electrical components and is input into a fault database for simulated operation. This allows for early fault diagnosis and prediction of electrical components in the gas filling chamber, thus preventing faults from occurring in advance and efficiently maintaining the safe operation of the gas filling cabinet for ultra-high voltage power transmission.

[0049] The drive assembly includes a gear cover 10, a driven gear 11, a driving gear 12, and a first motor 13. The gear cover 10 is fitted onto the circumferential surface of the guide post 7 and is fixedly connected to the inner wall of the cabinet 1. The driven gear 11 is fixedly connected to the circumferential surface of the guide post 7 and is located between the inner walls of the gear cover 10. The driving gear 12 is located between the inner walls of the gear cover 10 and meshes with the driven gear 11. The first motor 13 is fixedly connected to the side end of the cabinet 1, and the output end of the first motor 13 extends to the inner wall of the driven gear 11 and is fixedly connected to the driving gear 12.

[0050] In this invention, the gear cover 10 is used to accommodate the driven gear 11 and the driving gear 12. The driven gear 11 drives the lead screw 8 to rotate. The driving gear 12 drives the driven gear 11 to rotate through meshing with it. The first motor 13 drives the driving gear 12 to rotate. When it is necessary to move the infrared camera 20, the first motor 13 is powered on and started. The output end of the first motor 13 drives the driving gear 12 to rotate. The driving gear 12 drives the driven gear 11 to rotate through meshing with it. The driven gear 11 drives the lead screw 8 to rotate, thereby providing power for the movement of the infrared camera 20.

[0051] The linkage assembly includes a rotating shaft 18, a second motor 21, a push-pull rod 22, and a swing rod 23. The rotating shaft 18 is rotatably connected to the side end of the slider 9. One end of the rotating shaft 18 is fixedly connected to the mounting bracket 19, and the other end of the rotating shaft 18 extends to the other side end of the slider 9. The second motor 21 is fixedly connected to the side end of the slider 9, and the output end of the second motor 21 extends to the other side end of the slider 9. The swing rod 23 is fixedly connected to the other end of the rotating shaft 18. The push-pull rod 22 is fixedly connected to the output end of the second motor 21, and the push-pull rod 22 is rotatably connected to the swing rod 23.

[0052] In this invention, the rotating shaft 18 is used to support and fix the ratchet cover 14, the second motor 21 is used to drive the push-pull rod 22 to deflect, the push-pull rod 22 is used to push and pull the swing rod 23 to deflect, and the swing rod 23 is used to drive the rotating shaft 18 to deflect. When the scanning end of the infrared camera 20 is tilted at an angle, the pawl 16 is released from the ratchet 15, the second motor 21 is started by power, the output end of the second motor 21 drives the push-pull rod 22 to deflect, the push-pull rod 22 drives the swing rod 23 to deflect through the rotational connection with the swing rod 23, the swing rod 23 drives the rotating shaft 18 to deflect, and the rotating shaft 18 drives the mounting bracket 19 to deflect, so that the mounting bracket 19 drives the infrared camera 20 to tilt at an angle, so that the infrared camera 20 can expand the scanning angle by tilting, which facilitates the ultra-high voltage power transmission gas-filled cabinet based on the intelligent monitoring system to perform a wide range of infrared fault diagnosis on the built-in electrical components.

[0053] The limiting assembly includes a ratchet cover 14, a ratchet 15, a pawl 16, and an electric push rod 17. The ratchet cover 14 is sleeved on the circumferential surface of the rotating shaft 18 and is fixedly connected to the side end of the slider 9. The ratchet 15 is fixedly connected to the circumferential surface of the rotating shaft 18 and is located between the inner walls of the ratchet cover 14. The pawl 16 is rotatably connected to the inner wall of the ratchet cover 14 and engages with the ratchet 15. The electric push rod 17 is fixedly connected to the side end of the ratchet cover 14, and the output end of the electric push rod 17 extends to the inner wall of the ratchet cover 14 and is rotatably connected to the pawl 16.

[0054] In this invention, the ratchet cover 14 houses the ratchet 15 and the pawl 16, and also supports and fixes the electric push rod 17. The ratchet 15 rotates synchronously with the rotating shaft 18. The pawl 16 restricts the rotation of the ratchet 15 by engaging with it. The electric push rod 17 deflects the pawl 16 by extending and retracting its output end. When the infrared camera 20 is tilted at an angle, the output end of the electric push rod 17 extends and pushes the pawl 16 away from the ratchet 15, thus releasing the pawl 16 from engaging with the ratchet 15, facilitating the interaction between the ratchet 15 and the rotating shaft 18. When the rotation of the 8-axis needs to be locked at the tilt angle of the infrared camera 20, the output end of the electric push rod 17 extends to push the pawl 16 to engage with the ratchet 15, thereby locking the rotation of the ratchet 15. This locks the rotation of the shaft 18, locking the mounting bracket 19 and the infrared camera 20 at the tilt angle. This allows the infrared camera 20 to perform point scanning of the flammable points of different electrical components through deflection and linear movement, enabling the gas-filled cabinet for ultra-high voltage power transmission based on the intelligent monitoring system to perform point scanning of the flammable points of electrical components.

[0055] The winding assembly includes a winding wire 24, a sliding sleeve 25, a winding cover 26, a winding wheel 27, a winding spring 28, a winding spring cover 29, a winding shaft 30, a circular partition 31, and an adapter sleeve 36. The winding spring cover 29 is fixedly connected to the inner wall of the cabinet 1, and the circular partition 31 is fixedly connected between the inner walls of the winding spring cover 29. The winding cover 26 is fixedly connected to the side end of the winding spring cover 29. The winding wheel 27 is disposed between the inner walls of the winding cover 26. The winding wire 24 is fixedly connected to one end of the infrared camera 20, and the other end of the winding wire 24 extends to the inner walls of the winding cover 26. The extension end of the winding line 24 is wound into the winding wheel 27, and the extension end of the winding line 24 passes through the winding wheel 27 and the winding shaft 30 to the side end of the cabinet 1. The winding shaft 30 movably passes through the circular partition 31, and one end of the winding shaft 30 is fixedly connected to the winding wheel 27. The adapter sleeve 36 is fixedly connected to the circumferential surface of the winding shaft 30. The coil spring 28 is disposed between the inner walls of the coil spring cover 29. One end of the coil spring 28 is fixedly connected to the adapter sleeve 36, and the other end of the coil spring 28 is fixedly connected to the coil spring cover 29. The circumferential surface of the lead screw 8 is movably fitted with a sliding sleeve 25, and the sliding sleeve 25 is fixedly connected to the winding line 24.

[0056] In this invention, the spring cover 29 houses the spring 28, the circular partition 31, and the adapter sleeve 36. The spring cover 29 also supports and fixes the winding cover 26. The roller 30 is rotatably connected to the roller 30, thus supporting it. The roller 27 winds and retracts the extension end of the winding line 24 by rotation. The winding line 24 transmits the electrical signal generated by the infrared camera 20 to the outside of the cabinet 1. The roller 30 rotates synchronously with the roller 27. The adapter sleeve 36 pushes the roller 30 to rotate. The spring 28 rotates by deformation. The sliding sleeve 25 provides auxiliary support for the winding line 24, preventing it from colliding with electrical components inside the cabinet 1. During the unidirectional movement of the infrared camera 20, the infrared camera 20 pulls one end of the winding line 24 out from the side of the winding cover 26, thus unwinding the wound line 24. The extension end of the winding line 24 drives the roller 27 to rotate in the forward direction. When the infrared camera 20 rotates, the roller 27 drives the roller 30 to rotate in the forward direction, which in turn drives the adapter sleeve 36 to rotate in the forward direction. The adapter sleeve 36 drives the coil spring 28 to unfold inside the coil spring cover 29, so that the coil spring 28 changes from being attached to the circumferential surface of the adapter sleeve 36 to being attached to the inner wall of the coil spring cover 29. When the infrared camera 20 resets, the coil spring 28 changes from being attached to the inner wall of the coil spring cover 29 to being wrapped around and attached to the circumferential surface of the adapter sleeve 36. At the same time, it pushes the adapter sleeve 36 to rotate in the reverse direction inside the coil spring cover 29. The adapter sleeve 36 drives the roller 30 to rotate in the reverse direction, and the roller 30 then drives the roller 27 to rotate in the reverse direction, winding the extension end of the winding wire 24 into the roller 27. This allows the winding wire 24 to provide a suitable length in real time during the reciprocating movement of the infrared camera 20, avoiding interference of the winding wire 24 with the infrared scanning end of the infrared camera 20 inside the cabinet 1, and improving the infrared scanning accuracy of the infrared camera 20 for various electrical components.

[0057] The positioning component includes an infrared laser emitter 33, which is fixedly connected to the side end of the slider 9 and is located between the guide post 7 and the lead screw 8.

[0058] In this invention, the infrared laser emitter 33 is used to emit infrared lasers into the inner wall of the cabinet 1 to locate the displacement of the infrared camera 20 in real time. By setting the limit range of the movement of the infrared camera 20 within the infrared laser emitter 33, the infrared camera 20 is prevented from colliding and being damaged by the cabinet 1.

[0059] An adapter 35 is fixedly connected to the extension end of the winding wire 24, an integrated terminal 6 is fixedly connected to the side end of the cabinet 1, a guide wire 32 is fixedly connected to the side end of the integrated terminal 6, and the other end of the guide wire 32 is connected to the adapter 35.

[0060] In this invention, the adapter 35 is used for the rotatable connection between the winding wire 24 and the guide wire 32, so that the winding wire 24 will not be broken when the winding wire 24 and the spool 30 are rotated. The integrated terminal 6 is used to store the fault database and the running program, and the guide wire 32 is used to import electrical signals into the integrated terminal 6.

A partition 3 is fixedly connected between the inner walls of the cabinet body 1. The partition 3 is located between the two door slots 2.

[0062] In this invention, two door slots 2 are used to accommodate two cabinet doors 4, and two cabinet doors 4 are used to seal the two door slots 2. A partition 3 is used to divide the space of the cabinet 1, and two sealing strips 5 are used to fill the gap between the two door slots 2 and the two cabinet doors 4 to improve the sealing performance of the cabinet 1.

[0063] The method for using gas-filled switchgear for ultra-high voltage power transmission based on an intelligent monitoring system includes the following steps:

[0064] S1. Troubleshooting:

[0065] During the operation of the ultra-high voltage transmission gas-filled switchgear based on the intelligent monitoring system, the first motor 13 is started by power-on. The output end of the first motor 13 drives the drive gear 12 to rotate. The drive gear 12 meshes with the driven gear 11, which in turn drives the driven gear 11 to rotate. The driven gear 11 drives the lead screw 8 to rotate. The lead screw 8, through sliding engagement with the slider 9, pushes the slider 9 to reciprocate linearly within the cabinet 1. The slider 9 drives the rotating shaft 18 to move. The rotating shaft 18 drives the mounting bracket 19 to move between the inner walls of the cabinet 1. The mounting bracket 19 drives the infrared camera 20, thereby enabling the infrared camera 20 to... The infrared camera 20 moves back and forth in a straight line within the cabinet 1. By moving back and forth, the infrared camera 20 scans the electronic components inside the cabinet 1 with infrared light. This allows the infrared camera 20 to perform regular inspections of various electrical components, inspect the contacts of electrical components and various abnormal temperature rise points in real time, and collect abnormal temperature data of abnormal temperature rise points to form fault temperature data of electrical components. This data is then input into the fault database formed by various electrical component faults for simulation operation. This allows for early fault diagnosis and fault prediction of electrical components in the inflation chamber, so as to eliminate the occurrence of faults in the inflation chamber in advance and realize the fault diagnosis of electrical components in the inflation chamber.

[0066] S2. Targeted investigation:

[0067] During the reciprocating movement of the infrared camera 20, the pawl 16 disengages from the ratchet 15, energizing the second motor 21. The output of the second motor 21 drives the push-pull rod 22 to deflect. The push-pull rod 22, through its rotational connection with the swing rod 23, drives the swing rod 23 to deflect as well. The swing rod 23 then drives the rotating shaft 18 to deflect, which in turn drives the mounting bracket 19 to deflect. This causes the mounting bracket 19 to tilt the infrared camera 20, allowing the infrared camera 20 to expand its scanning angle through this tilt. Simultaneously, the output of the electric push rod 17 extends, pushing the pawl 16 away from the ratchet 15, thus disengaging the pawl 16 from the ratchet 15. The ratchet 15 and the rotating shaft 18 are engaged to facilitate rotation. When it is necessary to lock the tilt angle of the infrared camera 20, the output end of the electric push rod 17 extends to push the pawl 16 to engage with the ratchet 15, thereby locking the rotation of the ratchet 15 and locking the rotation of the rotating shaft 18. This locks the mounting bracket 19 and the infrared camera 20 at the tilt angle, allowing the infrared camera 20 to perform point scanning of the flammable points of different electrical components through deflection and linear movement. This enables the gas-filled cabinet for ultra-high voltage power transmission based on the intelligent monitoring system to perform point scanning of the flammable points of electrical components, thereby enabling point-to-point troubleshooting of electrical component faults within the cabinet 1.

[0068] S3, Interference Cancellation:

[0069] When the infrared camera 20 is troubleshooting electrical components inside cabinet 1, during its unidirectional movement, it pulls one end of the winding wire 24 out from the side of the winding cover 26, thus unwinding the winding wire 24. The extended end of the winding wire 24 drives the winding wheel 27 to rotate forward, which in turn drives the winding shaft 30 to rotate forward. The winding shaft 30 then drives the adapter sleeve 36 to rotate forward, causing the adapter sleeve 36 to unfold the coil spring 28 within the coil spring cover 29. This causes the coil spring 28 to change from being attached to the circumferential surface of the adapter sleeve 36 to being attached to the inner wall of the coil spring cover 29. When the infrared camera 20 resets, the coil spring 28... Spring 28 changes from being in contact with the inner wall of spring cover 29 to being wrapped around the circumferential surface of adapter sleeve 36. At the same time, it pushes adapter sleeve 36 to rotate in the opposite direction inside spring cover 29. Adapter sleeve 36 drives roller 30 to rotate in the opposite direction. Roller 30 then drives roller 27 to rotate in the opposite direction, winding the extension end of winding line 24 into roller 27. This allows winding line 24 to provide a suitable length in real time during the reciprocating movement of infrared camera 20, preventing winding line 24 from interfering with the infrared scanning end of infrared camera 20 inside cabinet 1, improving the infrared scanning accuracy of infrared camera 20 for various electrical components, and eliminating interference from winding line 24 to infrared camera 20.
