[0002] High-voltage switchgear refers to equipment used in power systems for switching, control, and protection in power generation, transmission, distribution, energy conversion, and consumption. High-voltage switchgear uses a wide variety of components, including busbar trays. Existing high-voltage switchgear busbar trays have several drawbacks. After installation, it's difficult to fine-tune the height of the busbar tray, and connecting it to high-voltage conductors at the interfaces is inconvenient, reducing the efficiency of the connection. Furthermore, existing high-voltage switchgear busbar trays lack protective interfaces, and this open design allows dust and foreign matter to easily accumulate at the connections during long-term operation, potentially leading to decreased insulation performance and increased short-circuit risk.

[0027] Please see Figures 1-5A busbar tray for a high-voltage switchgear includes a limiting shell 1. A first bidirectional lead screw 2 is rotatably mounted inside the limiting shell 1. One end of the first bidirectional lead screw 2 passes through the limiting shell 1 and is fixedly mounted with a throttle 3. Two drive seats 4 are threaded onto the first bidirectional lead screw 2. An mounting plate 5 is fixedly mounted on one side of the limiting shell 1. The mounting plate 5 has two limiting grooves 6. A limiting seat 7 is movably mounted in each limiting groove 6. A busbar tray body 8 is fixedly connected to both limiting seats 7. Multiple connectors 9 are provided at both ends of the busbar tray body 8. A limiting frame 10 is fixedly mounted at the lower end of the busbar tray body 8. Two push seats 11 are slidably mounted inside the limiting frame 10. Support rods 12 are hinged between the two push seats 11 and the two drive seats 4, and the two support rods 12 are rotatably connected to each other.

[0028] In this embodiment, the mounting plate 5 is provided with multiple mounting holes, through which bolts can be used to fix the entire device into the high-voltage switchgear. When it is necessary to adjust the height of the installed busbar bridge body 8, the throttle 3 is turned, which drives the first bidirectional lead screw 2 to rotate. Since the first bidirectional lead screw 2 is provided with two threaded areas in opposite directions, the two drive seats 4 move in adjacent directions. The drive seats 4 drive the support rod 12 to rotate, and the support rod 12 drives the push seat 11 to move along the sliding connection with the limit frame 10. While the support rod 12 rotates, it pushes the push seat 11 upward. The push seat 11 pushes the busbar bridge body 8 through the limit frame 10, so that the busbar bridge body 8 drives the two limit seats 7 to move along the limit groove 6, thereby adjusting the height of the busbar bridge body 8.

[0029] Please see Figures 1-5 As one embodiment of moving the protective cover 20: two protective plates 13 are fixedly installed at both ends of the busbar bridge body 8, a drive housing 14 is fixedly installed at the upper end of the busbar bridge body 8, a drive groove 15 is provided on the drive housing 14, two moving chambers 16 are provided inside the drive housing 14, the two moving chambers 16 are respectively arranged on both sides of the drive groove 15, a second bidirectional lead screw 17 is rotatably installed in the drive groove 15, a handle 18 is fixedly installed on the second bidirectional lead screw 17, both ends of the second bidirectional lead screw 17 extend into the moving chambers 16 and are threadedly connected to moving rods 19, one end of the moving rod 19 passes through the moving chamber 16 and is fixedly installed with the protective cover 20, two sealing rings 21 are fixedly installed on the protective cover 20, a positioning block 22 is fixedly installed on the moving rod 19, and two positioning grooves 23 that cooperate with the positioning block 22 are provided on the drive housing 14.

[0030] More specifically, after connecting the connector 9, the handle 18 is pushed through the drive groove 15. The handle 18 drives the second bidirectional lead screw 17 to rotate. Since the second bidirectional lead screw 17 has two threaded areas in opposite directions, the two moving rods 19 move in the direction of separation. The moving rods 19 drive the positioning block 22 to move along the positioning groove 23 to prevent the moving rods 19 from falling off. At the same time, the moving rods 19 drive the protective cover 20 to move, so that the protective cover 20 protects and prevents dust from the connection. The sealing ring 21 seals the protective cover 20 and the busbar bridge body 8. When it is necessary to move the protective cover 20 back to its original position, the handle 18 can be rotated in the opposite direction.

[0031] In summary, during the use or operation of the overall equipment: the mounting plate 5 is provided with multiple mounting holes, through which bolts can be used to fix the entire device to the high-voltage switchgear. When it is necessary to adjust the height of the installed busbar bridge body 8, the handle 3 is turned, which drives the first bidirectional lead screw 2 to rotate. Since the first bidirectional lead screw 2 is provided with two threaded areas in opposite directions, the two drive seats 4 move in adjacent directions. The drive seats 4 drive the support rod 12 to rotate, and the support rod 12 drives the push seat 11 to move along the sliding connection with the limit frame 10. While the support rod 12 rotates, it pushes the push seat 11 upward. The push seat 11 pushes the busbar bridge body 8 through the limit frame 10, so that the busbar bridge body 8 drives the two limit seats 7 to move along the limit groove 6, thereby adjusting the height of the busbar bridge body 8. After the handle 3 is used, it can be fixed to the limit shell 1 with bolts.

[0032] When dust prevention is required at the connection, after connecting the connector 9, push the handle 18 through the drive groove 15. The handle 18 drives the second bidirectional lead screw 17 to rotate. Since the second bidirectional lead screw 17 has two threaded areas with opposite directions, the two moving rods 19 move in the direction of separation. The moving rods 19 drive the positioning block 22 to move along the positioning groove 23 to prevent the moving rods 19 from falling off. At the same time, the moving rods 19 drive the protective cover 20 to move, so that the protective cover 20 protects and prevents dust at the connection. The sealing ring 21 seals the protective cover 20 and the busbar bridge body 8. When it is necessary to move the protective cover 20 back to its original position, simply rotate the handle 18 in the opposite direction.

[0033] In all the solutions mentioned above, those involving the operation of electrical components, unless otherwise specified, are controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known, and mature technologies, their electrical connections and specific circuit structures will not be elaborated here.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
