Description
Technical Field
[0001] This utility model relates to the field of cleaners, and more particularly to a GIS equipment testing device. Background Technology
[0002] Gas-insulated switchgear (GIS) is a metal-enclosed high-voltage power distribution device that uses sulfur hexafluoride (SF6) gas as the insulating medium. It integrates various electrical components such as circuit breakers, busbars, and instrument transformers. Its fully enclosed design offers advantages such as small footprint and high reliability, making it widely used in the power industry. The 220kV system has extremely high voltage and a very strong electric field inside the equipment. Any tiny insulation defect (such as burrs, floating potentials, or free particles) can trigger partial discharge under this strong electric field. While GIS is filled with SF6 gas, providing excellent insulation, insulation breakdown can still cause a short-circuit arc to rapidly release enormous energy within the confined space, potentially leading to catastrophic accidents such as explosions. This can not only damage the equipment but also cause widespread power outages.
[0003] Utility model publication CN202122645599.2 discloses a detection device for partial discharge testing of GIS equipment, comprising an insulating rod and a metal connector. The insulating rod is connected to a bracket via the metal connector, and the bracket is connected to a fixing box via bolts. A locking nut is threaded onto the side surface of the bolts. A sensor is installed inside the fixing box, and a top plate is provided on the top of the fixing box. Fixing blocks are provided on both the front and rear sides of the top plate. This detection device for partial discharge testing of GIS equipment, through the cooperation of the insulating rod, metal connector, bracket, bolts, fixing box, locking nut, sensor, top plate, fixing blocks, connecting plate, amplifier, and locking knob, achieves the effect of shortening the partial discharge testing time of GIS equipment, solving the problem of long detection time in traditional methods when conducting partial discharge testing of GIS equipment.
[0004] While the above structure can achieve the effect of detection without the need for staff to climb to a high place, if GIS equipment testing is carried out over a large area, the staff's arms are easily sore and swollen due to the continuous and large force during the long testing process.
[0005] Therefore, it is necessary to provide a new GIS equipment testing device to solve the above-mentioned technical problems. Utility Model Content

[0018] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of the structure of the GIS equipment testing device provided by this utility model; Figure 2 for Figure 1 A partial structural diagram of the structure shown; Figure 3 for Figure 1 The diagram shows the internal structure of the mounting box.

[0019] In the specific implementation process, such as Figures 1-5 As shown, the system includes a mounting box 1, inside which a support is provided. A moving device is installed inside the mounting box 1, and the moving device has two movable ends that can move in opposite directions. A rack 2 is fixed to each of the two movable ends. Two rotating shafts 3 are rotatably connected to the mounting box 1, and gears 4 are fixed to the rotating shafts 3. The two gears 4 mesh with the two racks 2 respectively. A rotating frame 5 is fixed to each of the two rotating shafts 3. The rotating frame 5 movably passes through an insertion hole 6 opened in the top wall of the mounting box 1. At least two arc plates 7 are fixed to the top of the rotating frame 5, and an extension frame 8 is fixed to the arc plate 7. A movable wheel 9 is rotatably connected to the extension frame 8. The at least two arc plates 7 on the rotating frame 5... The test piece 26 is installed together. When the device is used, the support moves the mounting box 1 to the vicinity of the equipment. Then, the moving device drives the two racks 2 to move towards each other and away from each other. The two gears 4 drive the two rotating frames 5 to rotate in opposite directions, so that the arc plates 7 on both sides move closer to each other. Finally, multiple movable wheels 9 are attached to the equipment. When the multiple movable wheels 9 move on the equipment, they drive the test piece 26 to move, realizing the detection of partial discharge of the equipment. During the movement of the device, the multiple movable wheels 9 move on the equipment, which achieves the effect of saving effort for operations that require long-term detection. Test component 26 includes a sensor and an amplifier. When the detector is turned on, the sensor is placed close to the device under test. It is responsible for sensing the raw physical signals generated by partial discharge (such as electromagnetic waves, ultrasonic waves, and pulse currents). After receiving the weak signal, the sensor converts it into an electrical signal and then transmits it to the amplifier. The amplifier amplifies and conditions this weak electrical signal, and the amplified signal is sent to the partial discharge detector or data acquisition card for display, analysis, and storage, and for diagnostic purposes. It should be noted that although this application has a lot of structures, it is only difficult to lift and remove. During the test, the device can be moved manually. Compared with long-term testing, this device is more labor-saving. In addition, lightweight materials, such as carbon fiber composite materials, can be used in the preparation. The moving device includes a threaded rod 10, a guide rod 11, a rotating component, and two transmission blocks 12. The threaded rod 10 is rotatably connected to the mounting box 1. The threaded rod 10 has left and right threads at both ends. The two transmission blocks 12 are threaded onto the left and right threads respectively and are fixed to two racks 2. The guide rod 11 is fixed to the mounting box 1 and movably passes through the two transmission blocks 12. The rotating component is mounted on the mounting box 1 and can drive the threaded rod 10 to rotate. The rotating component includes a frame 13 and a motor 14. A drive bevel gear 15 and a driven bevel gear 16 are provided. The frame 13 is fixed on the mounting box 1, and the motor 14 is fixed on the frame 13. The output end of the motor 14 is fixedly connected to the drive bevel gear 15, and the driven bevel gear 16 is fixed on the threaded rod 10. The drive bevel gear 15 and the driven bevel gear 16 mesh with each other. The motor 14 drives the drive bevel gear 15 to rotate, which in turn drives the driven bevel gear 16 to rotate, and then drives the threaded rod 10 to rotate, thereby causing the two transmission blocks 12 to move closer to each other or further away from each other. The support includes a threaded sleeve 17 and a support rod 18. The threaded sleeve 17 is fixed to the bottom wall of the mounting box 1. One end of the support rod 18 is provided with a threaded section. The support rod 18 is threaded to the inner wall of the threaded sleeve 17 through the provided threaded section. In use, the support rod 18 is threaded onto the threaded sleeve 17, and the support rod 18 is lifted to place the mounting box 1 near the equipment. The support also includes a support frame 19 fixed on both sides of the mounting box 1. A bearing frame 20 is rotatably connected to the support frame 19. The bearing frame 20 has at least two hanging holes 21 and a threaded bracket 22 is threadedly connected to the bearing frame 20. When the bearing frame 20 is in a horizontal state, the end of the threaded bracket 22 can move into the horizontal groove 23 opened in the support frame 19. When the bearing frame 20 is in a vertical state, the end of the threaded bracket 22 can move into the vertical groove 24 opened in the support frame 19. When using the bearing frame 20, the support rod 18 can be removed, the bearing frame 20 can be adjusted to a horizontal state, and the threaded bracket 22 can be rotated so that the end of the threaded bracket 22 moves into the horizontal groove 23 and hooks the hanging hole 21. The mounting box 1 can be placed near the equipment using a drone. When carrying the device, the end of the threaded bracket 22 can be moved into the vertical groove 24 so that the bearing frame 20 is in a vertical state, achieving a portable effect. Both ends of the support frame 19 are threadedly connected to the connecting frame 25. One end of the connecting frame 25 is a straight rod without threads. The straight rod can move into the straight groove opened in the bearing frame 20. When the bearing frame 20 is not in use and only the support rod 18 is used, the connecting frame 25 can be rotated to move the straight rod out of the straight groove, so that the bearing frame 20 can be removed. The bottom of the mounting box 1 is also fixedly connected to a hanging ear 27. When in use, the rope can be tied to the hanging ear 27. After the device is installed on the equipment, the rope can be pulled to move the movable wheel 9 in the testing device on the equipment.
