Description

[0001] This utility model relates to the technical field of instrument transformer testing, specifically to a wiring mechanism for instrument transformer testing. Background Technology

[0002] When calibrating instrument transformers, it is necessary to connect the primary wiring of the instrument transformer to the switchgear. Currently, in newly built and expanded substations, the primary equipment CTs of 35kV and 10kV are in the traditional cabinet-type instrument transformer testing equipment mode. The switchgear handcart switch is heavy, and when calibrating the instrument transformer, it is necessary to drag the handcart switch back and forth to press the primary wiring of the instrument transformer.

[0003] In the existing technology, during the wiring process, the current transformer is fixed between the clamps by holding the connecting rod and manually adjusting the position of the clamp and the conductive plate. This facilitates a series of tests and wiring of the current transformer by the staff. However, in actual use, the device requires manual adjustment. In confined spaces, it is impossible to move the clamp to the designated position by manual adjustment, making it inconvenient to clamp and fix the current transformers in different positions. Therefore, there is a need to improve the wiring mechanism for testing current transformers. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a wiring mechanism for transformer detection, which has the following advantages:

[0015] 1. The wiring mechanism for current transformer testing, through a set rotary adjustment mechanism, starts a motor one, which drives a trapezoidal screw one to rotate, causing the guide rod to move and synchronously pull the rotating frame to rotate. During the rotation of the rotating frame, the clamping plate connected to the right side is adjusted to the corresponding real-time vertical angle position. At the same time, starting a motor two causes a gear two to synchronously drive the clamping plate to rotate longitudinally, thereby changing the position of the clamping plate in real time and moving it to the appropriate current transformer. In the case of narrow spaces, the clamping plate can be quickly adjusted according to the needs, thus facilitating the clamping and fixing of current transformers in different positions.

[0016] 2.

[0026] Example 1:

[0027] Based on the existing technology, this device requires manual adjustment. However, in actual use, when encountering narrow spaces, it is impossible to move the clamping plate to the designated position through manual adjustment, thus making it inconvenient to clamp and fix the transformers in different positions. Please refer to Figures 1-5.

[0028] The rotary adjustment mechanism 6 includes a rotary component 61 and an adjustment component 62, with the adjustment component 62 disposed outside the rotary component 61.

[0029] Furthermore, the rotating assembly 61 includes a motor 611, which is fixedly connected to the right side of the support plate 55. A trapezoidal screw 612 is fixedly connected to the output end of the motor 611. A push block 613 is threadedly connected to the external side of the trapezoidal screw 612. A limit rod 614 is fixedly connected to the top of the support plate 55. A guide rod 615 is rotatably connected to the front of the push block 613. A rotating frame 616 is rotatably connected to the end of the guide rod 615 away from the push block 613. A rotating frame 617 is fixedly connected to the right side of the rotating frame 616 to facilitate rotation of the vertical angle.

[0030] Furthermore, a groove is provided at the corresponding position of the push block 613 and the limiting rod 614, and the push block 613 is slidably connected to the outside of the limiting rod 614, which facilitates the movement of the push block 613.

[0031] Furthermore, the trapezoidal screw 612 is rotatably connected to the front of the support plate 55, and the rotating frame 616 is rotatably connected to the front of the support plate 55, which facilitates the rotation of the rotating frame 616.

[0032] Furthermore, the adjustment component 62 includes a second motor 621, which is fixedly connected to the left side of the rotating frame 617. A first gear 622 is fixedly connected to the output end of the second motor 621. A second gear 623 is rotatably connected inside the rotating frame 617. An adjustment bracket 624 is fixedly connected to the right side of the second gear 623 to facilitate the adjustment of the longitudinal angle.

[0033] Furthermore, gear 622 meshes with gear 623, and electric push rod 7 is fixedly connected to the left side of adjustment frame 624. The top of adjustment plate is fixedly connected to connecting plate 9, which facilitates the rotation of gear 623.

[0034] Example 2:

[0035] Based on the existing technology's need to adjust the appropriate height, please refer to Figure 5 and, in conjunction with Embodiment 1, further it is found that the lifting mechanism 5 includes a motor 3 51, which is fixedly connected to the bottom of the fixed sleeve 1. A trapezoidal screw 2 52 is fixedly connected to the output end of the motor 3 51. A retaining sleeve 54 is threadedly connected to the outside of the trapezoidal screw 2 52. A sliding rod 53 is fixedly connected to the outside of the retaining sleeve 54. A support plate 55 is fixedly connected to the top of the retaining sleeve 54 to facilitate adjustment of the lifting height.

[0036] Furthermore, a groove is provided at the corresponding position of the fixed sleeve 1 and the slide rod 53, and the slide rod 53 is slidably connected in the groove to facilitate restricting the movement of the sleeve 54.

[0037] In actual operation, when the device is in use, firstly, the controller 4, through the lifting mechanism 5, starts the motor 3 51 according to the required height. The motor 3 51 drives the trapezoidal screw 2 52 to rotate, causing the trapezoidal screw 2 52 to move the sleeve 54 along the guide rail 53, thereby quickly adjusting the height of the device. Furthermore, in confined spaces or different positions, the rotation adjustment mechanism 6 starts the motor 1 611, which drives the trapezoidal screw 1 612 to rotate. During the rotation of the trapezoidal screw 1 612, the push block 613 is simultaneously pulled, causing the push block 613 to move. During the movement of the push block 613, the guide rod 615 is simultaneously moved, allowing the guide rod 615 to move... During the process, the rotating frame 616 is pulled to rotate synchronously, and during the rotation of the rotating frame 616, the clamping plate 8 connected to the right side is adjusted to the corresponding real-time vertical angle position. At the same time, by starting the second motor 621, the second motor 621 drives the first gear 622 to rotate, which in turn drives the second gear 623 to rotate, which in turn drives the clamping plate 8 to rotate longitudinally, thereby changing the position of the clamping plate 8 in real time and moving it to the appropriate current transformer. In the case of narrow space, the position of the clamping plate 8 can be quickly adjusted according to the needs. Then, by starting the electric push rod 7, the electric push rod 7 drives the clamping plate 8 to move, thereby fixing the clamping plate 8 between the clamping plate 8 and the connecting plate 9.
