As a typical terminal distribution device, they are widely used in power systems and various industrial users, and are indispensable products in smart grids, directly affecting the safe and reliable operation of the power grid. Currently, existing domestic RNBs mainly include gas-insulated RNBs and solid-insulated RNBs. Among them, gas-insulated RNBs include SF6 gas-insulated RNBs, dry air RNBs, and nitrogen RNBs, which are widely used due to their excellent insulation performance, ease of processing, and low cost.

[0003] The structure of a gas-insulated ring main unit mainly consists of a gas box, a mechanism compartment, a cable compartment, and an instrument compartment. In the production process, the assembly sequence is as follows: first, the gas box, mechanism compartment, and cable compartment are assembled into a single unit to form the main cabinet body; then, the instrument compartment is assembled onto the main cabinet body; next, the wiring between the instrument compartment and the main cabinet body is completed; and finally, the instrument compartment is manually commissioned. This process currently has several drawbacks:

[0004] First, during instrument room commissioning, the instrument room needs to be installed onto the main cabinet body and various wiring connections need to be assembled before commissioning can begin. The instrument room itself is quite bulky, and installation requires a lot of manpower. Second, if the instrument room fails to be commissioned, in addition to factors related to the instrument room itself, it may also be affected by various structural elements of the main cabinet body, making it difficult to troubleshoot the fault points in the instrument room. Summary of the Invention

[0005] This utility model addresses the problem of difficult operation during manual wiring and debugging of the instrument room of a ring main unit during production and commissioning, and provides a testing device for the instrument room of a ring main unit.

An eleventh link is connected to the output shaft of the tenth motor through a first universal joint coupling. The eleventh link is hollow, and a twelfth link is inserted into the end of the eleventh link away from the tenth motor. The end of the twelfth link away from the eleventh link is connected to the switch operating mechanism through a second universal joint coupling. The design of the ring-shaped sixth support and the multi-link design with universal joint couplings gives the switch operating mechanism greater freedom of movement. The tenth motor can drive the switch operating mechanism to rotate through the first universal joint coupling and the eleventh and twelfth links, which can meet the multi-angle operation requirements of different types of switches such as knobs and levers.

One end of the third connecting rod 440 is connected to the first connecting rod 438 by a pin, and the other end is connected to the first... The four-link 441 is connected by a pin and can swing relative to other links. The fourth link 441 has the same length as the third link 440. One end is connected to the second link 439 by a pin, and the other end is connected to the third link 440 by a pin. It can swing relative to other links. Under the combined drive of the second motor 436 and the third motor 437, and through the interaction of the first link 438, the second link 439, the third link 440, and the fourth link 441, two-degree-of-freedom transmission is achieved, which allows the first rotary seat 442 to quickly and accurately reach any position in the horizontal direction.

Under the combined drive of the sixth motor 456 and the seventh motor 457, and the interaction of the fifth link 458, the sixth link 459, the seventh link 460, and the eighth link 461, a two-degree-of-freedom transmission is achieved, which allows the second rotary seat 462 to quickly and accurately reach any position in the horizontal direction. The second rotating seat 462 is fixedly installed below the eighth connecting rod 461, and the fourth motor 443 is installed on its lower side. The eighth motor 463 is fixedly installed on the lower side of the second rotating seat 462. The fifth support 464 is fixedly connected to the eighth motor 463. The rotation of the eighth motor 463 can drive the rotation of the fifth support 464. The second gripper cylinder 465 is fixedly installed on the fifth support 464 and can drive the second gripper 466 to perform clamping or releasing actions. There are two second grippers 466, which are assembled on the second gripper cylinder 465. Under the drive of the second gripper cylinder 465, they can move closer to or further away from each other. The second connector 467 is the object clamped by the second connector device 45. One side is connected to the debugging mother wiring, and the other side can be connected to the second connector socket under the movement of the second connector device 45 to realize data transmission.

[0038] The second connector 45 operates as follows:

[0039] The second gripper cylinder 465 is driven to make the second gripper 466 firmly grasp the first connector 447. The fifth motor 452 is driven to rotate the second lead screw 453, causing the second slide table 455 to move vertically under the guidance of the second slide rail 454. This allows the height position of the second connector 467 to reach the lower side of the bottom of the second socket in the instrument compartment. Under the combined drive of the sixth motor 456 and the seventh motor 457, and through the interaction of the fifth link 458, the sixth link 459, the seventh link 460, and the eighth link 461, a two-degree-of-freedom transmission is achieved, which allows the second rotary seat 462 to quickly and accurately reach the vicinity of the horizontal position of the second socket.

[0040] The eighth motor 463 drives the fifth support 464, the second gripper cylinder 465, and the second gripper 466 to rotate, ensuring the second connector 467 is precisely positioned below the second socket. The two components are horizontally aligned. The fifth motor 452 then drives the second connector 467 upwards, assembling it into the second socket for insertion and data transmission. The vertical movement of the slide driven by the fifth motor 452 and the rotation of the gripper driven by the eighth motor 463 are series drives, while the horizontal movement of the rotating seat driven by the eighth and seventh motors 457 is a parallel drive. This series-parallel coupling transmission allows for rapid and precise movement of the connector over long distances, improving the device's speed and accuracy. The insertion of the second connector 467 into the second socket is fully automated, significantly improving efficiency. After the insertion of the first and second connectors and sockets is completed, the instrument chamber is activated. The main unit can then pressurize or apply current to the instrument chamber to test the functionality of its components.

[0041] like Figure 7-9As shown, the switch driving device 47 includes a bracket 471. Three sets of third linkage assemblies are evenly arranged circumferentially on the bracket 471. The motion plane of the third linkage assembly is perpendicular to the plane of the bracket 471. Each third linkage assembly includes a ninth linkage 474. The first end of the ninth linkage 474 is connected to a ninth motor 472. A gearbox 473 is provided between the ninth linkage 474 and the ninth motor 472. The gearbox 473 and / or the ninth motor 472 are mounted on the bracket 471. The second end of the ninth linkage 474 is hinged to a tenth linkage 475. The end of the tenth linkage 475, one of the three sets of third linkage assemblies, away from the ninth linkage 474, is connected to a sixth support 481. A switch operating mechanism is mounted on the sixth support 481, which is annular. The three tenth linkages 475 are hinged outside the annulus of the sixth support 481. The switch operating mechanism is rotatably mounted inside the annulus of the sixth support 481. A tenth linkage is located at the center of the bracket 471. The output shaft of the tenth motor 476 is connected to an eleventh link 478 via a first universal joint coupling 477. The eleventh link 478 is hollow. A twelfth link 479 is inserted into the end of the eleventh link 478 away from the tenth motor 476. The end of the twelfth link 479 away from the eleventh link 478 is connected to the switch operating mechanism via a second universal joint coupling 480. The switch operating mechanism includes a clamping plate support 482, and the clamping plate support 482 is connected to the second universal joint coupling 480. A coupling 480 is connected, and a first clamping plate 483 and a second clamping plate 484 are mounted opposite each other on the clamping plate support 482. The first clamping plate 483 and the second clamping plate 484 are provided with through holes, and screws 485 are provided in the through holes. A compression spring 486 is also sleeved on the screws 485. The compression spring 486 can cause the first clamping plate and the second clamping plate to move closer to the clamping plate support. A cylinder 487 is also provided at the front end of the clamping plate support 482, and the cylinder rod 488 of the cylinder 487 faces the side away from the clamping plate support 482.

[0042] The switch drive device 47 is installed on the front center side of the main mounting plate 42 to enable or disable the switches of external components in the instrument compartment, thereby testing the functions of various components inside the instrument compartment.

[0043] The bracket 471 serves as the base for the switch drive device 47, mounted in the center of the front of the main mounting plate 42. Its overall structure is triangular. Three gearboxes 473 are mounted at the bottom of the three corners of the bracket 471, enabling speed changes for the ninth motor 472. Three ninth motors 472 are fixedly mounted on the three gearboxes 473, driving the clamping plate to move spatially. Three ninth links 474 are mounted on the three gearboxes 473. The ninth motors 472 drive the gearboxes 473, causing the ninth links 474 to swing. Six tenth links 475 are present, with two tenth links 475 mounted on each side of each ninth link 474 via ball pins. The swinging of the ninth links 474 drives the tenth links 475. The tenth motor 476 is mounted in the middle of the bracket 471, driving the clamping plate to rotate. The first universal joint coupling... One end of the device 477 is mounted on the tenth motor 476, and the other end is mounted on the eleventh link 478. The eleventh link 478 is mounted on the first universal joint coupling 477 and has a hollow cylindrical structure inside. One end of the twelfth link 479 is mounted on the second universal joint coupling 480, and the other end is assembled in the hollow cylinder of the eleventh link 478. The twelfth link 479 can slide relative to the eleventh link 478, but the two will not rotate relative to each other. One end of the second universal joint coupling 480 is mounted on the twelfth link 479, and the other end is fixedly connected to the clamping plate support 482. The sixth support 481 is connected to the six tenth links 475 on all four sides through ball pins, creating a kinematic connection between the six tenth links 475. The clamping plate support 482 is mounted on the sixth support 481, and its bottom end is connected to the second universal joint coupling 480, and it can rotate relative to the sixth support 481.

[0044] Three ninth motors 472 drive the gearbox 473, ninth link 474, and tenth link 475 in sequence, thereby enabling the sixth support 481 to move in space, and the plane of the sixth support 481 is always parallel to the plane of the bracket 471. When the seventeenth support approaches or moves away from the bracket 471, the twelfth link 479 extends into or out of the eleventh link 478, driving the tenth motor 476, which in turn drives the first universal joint coupling 477, the eleventh link 478, the twelfth link 479, the second universal joint coupling 480, and the clamping plate support 482 to rotate, thereby causing the two clamping plates to rotate. The first clamping plate 483 and the second clamping plate 484 are mounted on both sides of the clamping plate support 482 by four screws 485 and secured with self-locking nuts. The static distance between the two clamping plates is slightly less than the thickness of the rotary switch knob.

[0045] A semi-circular notch is provided between the first clamping plate 483 and the second clamping plate 484 to facilitate the extension of the cylinder rod 488. Rectangular protrusions with rounded corners are provided on both sides of the ends of the first clamping plate 483 and the second clamping plate 484, allowing them to engage a toggle switch. The first clamping plate 483 and the second clamping plate 484 can function as a button, knob, and toggle switch, achieving a three-in-one function. Eight compression springs 486 are provided, one on each screw 485 on both sides of the first clamping plate 483 and the second clamping plate 484. This allows the first clamping plate 483 and the second clamping plate 484 to elastically press against the clamping plate support 482. The cylinder 487 is fixedly mounted on the clamping plate support 482, and the cylinder rod 488 is assembled on the cylinder 487, allowing it to extend or retract under the drive of the cylinder 487. When the cylinder rod 488 extends, its height should be greater than the height of the rectangular protrusion of the clamping plate. When the cylinder rod 488 retracts, its height should be lower than the height of the inner surface of the clamping plate, so as not to affect the opening and closing of the knob. The outer diameter of the cylinder rod 488 is smaller than the outer diameter of the push-button switch.

[0046] The operation of the switch drive device 47 is as follows:

[0047] The three ninth motors 472 drive the gearbox 473, ninth link 474, and tenth link 475 to move sequentially, thereby realizing the spatial movement of the sixth support 481. Finally, the first clamping plate 483 and the second clamping plate 484 are positioned directly in front of the switch on the instrument panel surface. The push-button switch operation involves: driving cylinder 487 to extend and retract cylinder rod 488, thus closing the push-button switch; then driving cylinder 487 again to extend and retract cylinder rod 488, thus disengaging the push-button switch. The rotary switch operation involves: when the clamping plate is positioned... After the rotary switch is directly in front, the ninth motor 472 continues to drive, causing the two clamping plates to move forward and touch the rotary switch. The knob then slowly enters the two clamping plates. Due to the action of the compression spring 486, the clamping plates are opened by the knob, but are still pressed against the knob. The tenth motor 476 drives the first universal joint coupling 477, the eleventh link 478, the twelfth link 479, the second universal joint coupling 480, and the clamping plate support 482 to rotate, thereby causing the two clamping plates to rotate and thus driving the rotary switch to different positions.

[0048] Toggle switch operation: When the clamping plate stops directly in front of the rotary switch, the ninth motor 472 continues to drive, causing the two clamping plates to move forward and touch the toggle switch, thus forcing the toggle switch to open or close. The first clamping plate 483 and the second clamping plate 484 realize a three-in-one control function, improving the flexibility of device testing and debugging. By controlling the opening and closing of the push button switch, rotary switch, and toggle switch, the electrical components are controlled, thereby realizing the testing and debugging of the entire ring main unit. Through the testing and debugging device, the data transmission, testing, and debugging of the instrument room can be automated, realizing the automated operation of instrument room testing and debugging, greatly improving production efficiency. Moreover, the automated operation has high accuracy, no human factor influence, stable test results, and high reliability.
