Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically a testing device for live display of high voltage switchgear. Background Technology
[0002] High-voltage switchgear live indicator is used in power systems to transmit signals of whether a high-voltage live body is energized to light-emitting or sound-emitting elements, displaying or simultaneously locking high-voltage switchgear, thus preventing electrical misoperation of equipment and ensuring personal safety.
[0003] To rigorously test product quality and ensure the quality of live-line indicators before they leave the factory, it is necessary to test whether the high-voltage live-line indicators can function properly before they leave the factory. The existing inspection method involves inspectors placing the live-line indicator on the voltage-transmitting test stand and observing the indicator's illumination to judge its quality. This method only performs a single inspection of the live-line indicator, which is prone to error and affects the inspection results. To address this issue, we have proposed a high-voltage switchgear live-line indicator inspection device. Utility Model Content

The output end of the servo motor is connected to a rotating rod, which is rotatably mounted at the center of the inspection table. A sliding groove is opened at the top of the rotating rod, and a sliding rod is slidably connected in the groove. A mounting block is fixedly welded to the top of the sliding rod, and a spring is sleeved on the sliding rod. The two ends of the spring are fixedly connected to the rotating rod and the mounting block, respectively. Three annularly distributed connecting posts are fixedly welded to the mounting block. A placement frame is fixedly welded to the end of the connecting posts away from the mounting block. A live indicator is placed on the placement frame, and a power receiving groove is provided at the bottom of the live indicator. Two power-conducting inspection seats are fixedly installed on the top wall of the inspection table, and conductive posts are installed on the power-conducting inspection seats.
[0007] Preferably, the two power-on test seats are respectively located directly below the two rear placement frames, and the conductor post is located directly below the power connection slot behind the power-on display placed in the rear placement frame.
[0008] Preferably, an L-shaped mounting rod is fixedly welded to the rear side wall of the inspection table, a hydraulic rod is fixedly mounted on the L-shaped mounting rod, a pressure block is fixedly mounted at the bottom end of the hydraulic rod, and the pressure block is positioned directly above the mounting block.
[0009] Preferably, a base is fixedly welded to both sides of the placement frame, a rotating column is rotatably mounted on the base, and a stop block is fixedly welded to the top of the rotating column.
[0010] Preferably, a controller is fixedly installed on the inspection table, and the controller is electrically connected to the servo motor and the hydraulic rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model uses a servo motor to drive a rotating rod to rotate three placement frames, which in turn drive the live display to pass through two power-on inspection seats in sequence. This allows the live display to be inspected twice during inspection, reducing inspection errors and ensuring inspection accuracy.
[0013] 2. When using this utility model, while the two rear placement frames are driving the live indicator for inspection, the inspector can remove the live indicator that has been inspected on the front placement frame and reinstall a new live indicator to be tested, saving time and improving inspection efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a live indicator testing device for high-voltage switchgear, comprising:
[0020] Inspection table 1, with multiple support legs 2 fixedly welded to its bottom wall, a servo motor 3 fixedly installed in the middle of the bottom wall of inspection table 1, a rotating rod 4 connected to the output end of the servo motor 3, the rotating rod 4 rotatably installed at the center of inspection table 1, a sliding groove 5 opened at the top of the rotating rod 4, a sliding rod 6 slidably connected in the sliding groove 5, a mounting block 7 fixedly welded to the top of the sliding rod 6, a spring spring 8 sleeved on the sliding rod 6, the two ends of the spring spring 8 being fixedly connected to the rotating rod 4 and the mounting block 7 respectively, three annularly distributed connecting posts 9 fixedly welded to the mounting block 7, a placement frame 10 fixedly welded to the end of the connecting post 9 away from the mounting block 7, a live indicator 11 placed on the placement frame 10, a power receiving groove 12 provided at the bottom of the live indicator 11, two power-conducting inspection seats 13 fixedly installed on the top wall of inspection table 1, and conductive posts 14 installed on the power-conducting inspection seats 13.
[0021] The two power-on test bases 13 are respectively located directly below the two rear placement frames 10. The lead post 14 is located directly below the power connection slot 12 behind the rear placement frame 10, so that when the placement frame 10 moves the power-on test base 13 to rotate the power-on display 11 to above the power-on test base 13, the lead post 14 can be accurately inserted into the power connection slot 12.
[0022] An L-shaped mounting rod 16 is fixedly welded to the rear side wall of the inspection table 1. A hydraulic rod 17 is fixedly mounted on the L-shaped mounting rod 16. A pressure block 18 is fixedly mounted at the bottom end of the hydraulic rod 17. The pressure block 18 is positioned directly above the mounting block 7. The hydraulic rod 17 can drive the pressure block 18 to move downward to squeeze the mounting block 7, thereby driving multiple placement frames 10 to move downward.
[0023] A base 19 is fixedly welded to both sides of the placement frame 10. A rotating column 20 is rotatably mounted on the base 19. A stop block 21 is fixedly welded to the top of the rotating column 20. The stop block 21 can rotate through the rotating column 20 and fit against the top wall of the live display 11, thereby limiting and fixing the live display 11 placed on the placement frame 10.
[0024] A controller 15 is fixedly installed on the inspection table 1. The controller 15 is electrically connected to the servo motor 3 and the hydraulic rod 17.
[0025] Working principle: When using this utility model, the live indicator 10 to be inspected is placed on the front placement frame 10. The stop block 21 is rotated to the top wall of the live indicator 10 to limit and fix the live indicator 10. Then, the servo motor 3 is run by the controller 15. The servo motor 3 drives the rotating rod 4 to rotate, thereby rotating the front placement frame 10 to directly above the rear power-on inspection seat 13. Then, the hydraulic rod 17 is run by the controller 15. The hydraulic rod 17 drives the pressure block 18 to move downward, pressing the mounting block 7, so that the placement frame 10 moves the live indicator 10 downward, so that the conductive post 14 is inserted into the electrical connection slot 12, energizing the live indicator 11. The lighting status of the live indicator 11 is observed. During the inspection process, the inspector can install a new live indicator 11 in the empty placement frame 10 that has been rotated to the front for inspection.
