Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 - 4 , a mutual inductor harmonic eliminator verification device, including a verification table 1 and an adjusting frame 5. A detection electrode 6 is installed at the bottom of the adjusting frame 5. A placement table 2 is provided on the top of the verification table 1. A placement rack 11 is fixedly connected to one side of the placement table 2. A moving component 3 is provided on the placement rack 11;

[0027] The moving component 3 includes a motor 31. The output end of the motor 31 is connected to a first threaded rod 32. The first threaded rod 32 is rotatably arranged on the placement rack 11. A first sliding rod 34 is arranged in parallel below the first threaded rod 32. The first sliding rod 34 is fixed on the placement rack 11. The first threaded rod 32 is in threaded connection with the moving frame 33. The first sliding rod 34 penetrates through the bottom of the moving frame 33. An adjusting component 4 is installed on the moving frame 33;

[0028] The adjusting component 4 includes a second threaded rod 42. The second threaded rod 42 is rotatably installed on the top of the moving frame 33. A moving block 43 is in threaded connection with the second threaded rod 42. The bottom of the moving block 43 is connected to the adjusting frame 5 through an electric telescopic rod 7;

[0029] A moving groove 44 is opened at the top of the moving frame 33. The moving block 43 passes through the moving groove 44 and is slidably connected to the moving groove 44. The electric telescopic rod 7 is arranged below the moving groove 44;

[0030] One end of the second threaded rod 42 is fixedly connected to a runner 41.

[0031] Specifically, by setting the moving component 3, the moving component 3 is used to adjust the position of the adjusting component 4. When the connection points on the harmonic eliminator are close to the same end of the harmonic eliminator, after the harmonic eliminator is placed on the placement table 2, the connection points on the harmonic eliminator are on the same side of the placement table 2. Therefore, to facilitate the corresponding connection between the detection electrode 6 and the connection point of the harmonic eliminator, the motor 31 in the moving component 3 is used to control the rotation of the first threaded rod 32. The first threaded rod 32 is helically connected to the moving frame 33, so that the moving frame 33 moves along the first slide rod 34 during the rotation of the first threaded rod 32. Thus, the adjusting component 4 together with the adjusting frame 5 is driven by the moving frame 33 to move to one side close to the connection point. A bidirectional threaded rod is installed inside the adjusting frame 5, which can control the detection electrodes 6 at both ends of the bottom of the adjusting frame 5 to move towards or away from each other, so as to connect with the connection points on harmonic eliminators of different sizes;

[0032] The adjusting component 4 is used to adjust the position of the adjusting frame 5. When the staff places the harmonic eliminator on the placement table 2, due to certain errors in manual placement, although the harmonic eliminator is placed in the middle area of the placement table 2, the distances between the harmonic eliminator and the moving frame 33 are not uniform. As a result, the detection electrodes 6 on the adjusting frame 5 cannot accurately correspond to the connection points on the harmonic eliminator. When adjusting with the adjusting component 4, the staff rotates the runner 41, and the rotation of the runner 41 drives the rotation of the second threaded rod 42. Utilizing the helical connection between the second threaded rod 42 and the moving block 43, and the adaptation of the moving block 43 to the moving groove 44, the second threaded rod 42 can drive the moving block 43 to move along the moving groove 44 during rotation, thereby making a longitudinal adjustment of the adjusting frame 5 on the horizontal plane, ensuring that no matter where the harmonic eliminator is clamped in the middle area of the placement table 2, the corresponding connection between the detection electrode 6 under the adjusting frame 5 and the connection point on the harmonic eliminator can be achieved.

[0033] Embodiment 2:

[0034] To achieve the rapid fixation of the harmonic eliminator, please refer to Figures 1 - 4 , on the basis of Embodiment 1, a sliding groove 21 is opened on the placement table 2, and the sliding grooves 21 are symmetrically arranged on both sides of the placement table 2;

[0035] A fixing plate 22 is slidably installed in the sliding groove 21. The fixing plate 22 is C-shaped, and both ends of the fixing plate 22 pass through the sliding groove 21 and are arranged at the bottom of the placement table 2;

[0036] Two slide rods 23 are fixedly installed on both sides of the bottom of the placement table 2. The two ends of the fixing plate 22 are respectively slidably connected to the two slide rods 23 on both sides of the bottom of the placement table 2. A spring 24 is sleeved on the slide rod 23, and the fixing plate 22 is connected to the side wall of the placement table 2 through the spring 24.

[0037] The spring 24 has elasticity. When the operator places the harmonic eliminator on the placement table 2, the spring 24 is compressed to generate elastic force. The elastic force acts on the fixed plate 22, applying pressure to the fixed plate 22 towards the harmonic eliminator, thereby achieving clamping and fixing of the harmonic eliminator. The elasticity of the spring 24 enables the fixed plate 22 to adapt to harmonic eliminators of different sizes within a certain range. When the size of the harmonic eliminator changes, the spring 24 will be compressed or extended accordingly to maintain the clamping force on the harmonic eliminator. The elastic coefficient of the spring 24 determines the magnitude of the clamping force. By selecting a suitable spring 24, it can be ensured that the clamping force is large enough to fix the harmonic eliminator without being too large to damage the harmonic eliminator, so as to achieve the best clamping effect. When it is necessary to place the harmonic eliminator, the fixed plate 22 is opened, and the fixed plate 22 is moved along the second slide bar 23 to squeeze the spring 24, causing the spring 24 to undergo elastic deformation. After placing the harmonic eliminator, the fixed plate 22 automatically closes under the action of the spring 24 and clamps the harmonic eliminator, enabling the operator to quickly place or remove the harmonic eliminator from the placement table 2, with simple and fast operation.

[0038] Working principle: When the device is in use, the operator places the harmonic eliminator on the placement table 2, and uses the spring 24 to push the fixed plate 22 to apply pressure to the harmonic eliminator, so that the harmonic eliminator is clamped and fixed on the placement table 2. By rotating the bidirectional threaded rod inside the adjusting frame 5, the detection electrodes 6 at both ends of the adjusting frame 5 are driven to move towards or away from each other, so that the distance between the two detection electrodes 6 is the same as the distance between the two connection points on the harmonic eliminator. Depending on whether the two connection points on the harmonic eliminator are at both ends or the same end of the harmonic eliminator, when the two connection points on the harmonic eliminator are at the same end, the moving component 3 is adjusted. The motor 31 is used to drive the first threaded rod 32 to rotate, and then the moving frame 33 is controlled to move along the first slide bar 34, facilitating the movement of the detection electrode 6 driven by the adjusting frame 5 to the same side as the connection point. By rotating the runner 41, the second threaded rod 42 is driven to drive the moving block 43 to move along the moving groove 44, and then the adjusting frame 5 is driven to move longitudinally on the horizontal plane, so that the detection electrode 6 can correspond to the connection point, and when the electric telescopic rod 7 extends, it can cause the detection electrode 6 to be connected to the connection point, facilitating the operator to calibrate the harmonic eliminator.
