Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of current transformers, and particularly relates to a current transformer iron core wrapping structure. Background Art
[0002] The wrapping structure of the current transformer iron core refers to the design of covering or encapsulating the iron core part of the current transformer. This structure usually uses insulating materials or magnetic materials to protect the iron core, fix its position, and prevent electromagnetic interference or external damage during the operation of the current transformer. The wrapping structure can be achieved by methods such as wrapping, fixing, or sealing the iron core to ensure its stability and reliability in the working environment, and at the same time help improve the accuracy and long-term stability of the current transformer;
[0003] After retrieval, a Chinese patent with the publication number: CN217134201U discloses a current transformer iron core winding device. It is recorded in this patent that one of the rotating shafts is driven to rotate by a machine. When the rotating shaft rotates, the belt pulley fixedly installed on the outer surface of the rotating shaft will drive another rotating shaft to rotate through a belt, so that the transmission wheels fixedly installed on the two rotating shafts can rotate simultaneously. The friction force of the two transmission wheels is used to drive the winding coil to rotate, and the winding ring on the winding coil drives the copper wire to wind on the surface of the iron core, with a convenient operation technical solution;
[0004] In this solution, although the friction force can be reduced, when winding iron cores with different inner diameters, since the inner diameters are different, the outer diameters are also different, resulting in a change in the distance between the iron core and the winding equipment, so that winding looseness and breakage will occur during winding, thus reducing the product quality and the working efficiency. To solve this technical problem, the utility model proposes a current transformer iron core wrapping structure. Summary of the Invention

Detailed Implementation Manner
[0023] 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.
[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0025] Embodiment 1: A current transformer core wrapping structure, including a support frame 1 and a circular bottom plate 8. The support frame 1 is composed of a horizontal plate and a vertical plate perpendicular to the horizontal plate. The circular bottom plate 8 is arranged on the top of the horizontal plate of the support frame 1. An adjusting mechanism 9 is arranged on the top of the circular bottom plate 8. At the same time, the adjusting mechanism 9 includes a pair of vertical plates 901, a threaded rod 904 and a threaded block 905. At the same time, the threaded block 905 is threadedly connected to the outer wall of the threaded rod 904. The inner side wall of the threaded block 905 is fixedly connected with a vertical rod 10. The top of the vertical rod 10 is fixedly connected with a housing 11. A semi-circular transformer core 19 is arranged inside the housing 11. A pair of horizontal plates 903 are fixedly connected to the outer side walls of both vertical plates 901. A motor two 902 is fixedly connected to the outer wall of one side horizontal plate 903. At the same time, the threaded rod 904 penetrates through the horizontal plate 903 and is fixedly connected to the output end of the motor two 902. The outer wall of the bottom of the vertical rod 10 is fixedly connected with a slider 907. A positioning rod 906 is fixedly connected between the other side horizontal plates 903. And the slider 907 is slidably connected to the outer wall of the positioning rod 906.
[0026] By starting the motor two 902 on the horizontal plate 903, the motor two 902 drives the threaded rod 904 to rotate, thereby controlling the forward and backward movement of the threaded block 905. During the movement of the threaded block 905, the position of the vertical rod 10 is adjusted. The vertical rod 10 is limited between the two vertical plates 901, and the slider 907 is limited on the positioning rod 906 to ensure the stability and consistency of the moving direction of the vertical rod 10. The movement of the vertical rod 10 guides the semi-circular transformer core 19 on the housing 11 to be precisely adjusted. Through the coordination of these operations, the precise wrapping of different arcs of the semi-circular transformer core 19 is achieved. This system design significantly improves work efficiency and accuracy.
[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a positioning mechanism 12 is provided inside the housing 11. The positioning mechanism 12 includes an electric push rod 1201, a groove 1204 and a pair of soft clamping plates 1203. The electric push rod 1201 is fixedly connected inside the housing 11. At the same time, the soft clamping plates 1203 are slidably connected inside the groove 1204. And a pair of semi-circular transformer cores 19 are arranged inside the groove 1204. The output end of the electric push rod 1201 is fixedly connected with a connecting rod 1202. And a pair of soft clamping plates 1203 are respectively fixedly connected to both ends of the connecting rod 1202. At the same time, the connecting rod 1202 is slidably connected inside the housing 11. A top cover 13 is fixedly installed on the top of the housing 11. The bottom of the support frame 1 is fixedly connected with a connecting frame 2. The bottom of the connecting frame 2 is fixedly connected with a first motor 3. At the same time, the output end of the first motor 3 is fixedly connected with a first rotating column 4. At the same time, a small gear 5 is fixedly connected to the outer wall of the first rotating column 4. And a second rotating column 7 is rotatably connected between the connecting frame 2 and the circular bottom plate 8. A large gear 6 is fixedly connected to the outer side wall of the second rotating column 7. At the same time, the small gear 5 meshes with the large gear 6. A third motor 14 is fixedly connected to the outer wall of the vertical plate of the support frame 1. The output end of the third motor 14 is fixedly connected with a rotating shaft 15. The other end of the rotating shaft 15 is fixedly connected with a circular plate 16. And a support rod 17 is fixedly connected to the outer wall of the circular plate 16. At the same time, a binding band 18 is arranged at the other end of the support rod 17.
[0028] After opening the top cover 13, place the semi-circular transformer core 19 into the groove 1204 and start the electric push rod 1201. The electric push rod 1201 pushes the soft clamping plates 1203 at both ends of the connecting rod 1202 to clamp one end of the semi-circular transformer core 19. Then close the top cover 13 to ensure that the semi-circular transformer core 19 is accurately positioned. Next, start the first motor 3 on the connecting frame 2, which drives the small gear 5 on the first rotating column 4, and then drives the large gear 6 and the internal second rotating column 7 to rotate. The movement of the second rotating column 7 causes the circular bottom plate 8 to slowly rotate. At the same time, start the third motor 14, which drives the rotating shaft 15, and the rotating shaft 15 causes the support rod 17 on the circular plate 16 to rotate. The support rod 17 wraps the semi-circular transformer core 19 through the binding band 18. These operations cooperate with each other, significantly improving the positioning accuracy and wrapping efficiency of the semi-circular transformer core 19, thus greatly improving the work efficiency and speed.
[0029] Working principle: When the staff needs to bandage the semi-circular transformer core 19, first open the top cover 13, then place the semi-circular transformer core 19 in the groove 1204. At this time, start the electric push rod 1201, and drive the soft clamping plates 1203 at both ends of the connecting rod 1202 to move through the electric push rod 1201, and clamp one end of the semi-circular transformer core 19. Then cover the top cover 13. Through their cooperation, rapid positioning of semi-circular transformer cores 19 of different sizes is achieved. After the positioning is completed, according to the radian of the semi-circular transformer core 19, the distance between the semi-circular transformer core 19 and the bandage 18 needs to be adjusted. By starting the second motor 902 on the cross plate 903, the second motor 902 drives the threaded rod 904 to rotate. The rotation of the threaded rod 904 will drive the threaded block 905 to move back and forth, and adjust the vertical rod 10 back and forth. When the vertical rod 10 moves, it will be limited between the two side vertical plates 901, and at the same time, the slider 907 is limited on the positioning rod 906 to ensure that the moving direction of the vertical rod 10 is consistent. When the vertical rod 10 moves, it will drive the semi-circular transformer core 19 on the outer shell 11 to be adjusted. Through their cooperation, precise bandaging of semi-circular transformer cores 19 with different radians is achieved, improving work efficiency. After the positioning and adjustment are completed, by starting the first motor 3 on the connecting frame 2, the first motor 3 drives the small gear 5 on the first rotating column 4 to rotate. The rotation of the small gear 5 will drive the large gear 6 and the second rotating column 7 inside to rotate. The rotation of the second rotating column 7 will drive the circular bottom plate 8 to rotate slowly. At this time, cooperate and start the third motor 14. The third motor 14 drives the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 will drive the support rod 17 on the circular plate 16 to rotate. At this time, the support rod 17 will drive the bandage 18 to bandage the semi-circular transformer core 19. With their cooperation, the work efficiency is greatly improved.
