[0002] Dry-type transformers are developed on the basis of traditional oil-immersed transformers. With the increasing requirements for safety, environmental protection and reliability, people began to explore new transformer technologies. Dry-type transformers were born in this context. They use special insulating materials and designs, and do not require the use of insulating oil, thus avoiding safety hazards such as oil leakage and fire, and are more environmentally friendly and safe. With the continuous advancement of materials science and technology, the performance of dry-type transformers has also been continuously improved, and they have gradually been widely used in various fields.
[0003] The existing coil winding tensioning device has a relatively simple effect. The coil needs to maintain appropriate tension during the winding process to ensure the tightness and stability of the coil. If the device is not set with tension adjustment, the coil may be too tight or too loose, resulting in an unstable coil structure, affecting the performance and life of the transformer. For this reason, we propose a dry-type transformer coil winding tensioning device. Utility Model Content

[0016] (III) Beneficial effects
[0017] Compared with the prior art, the utility model provides a dry-type transformer coil winding and tensioning device, which has the following beneficial effects:
[0018] When the dry-type transformer coil winding tensioning device is used, the raw material inside the raw material box is firstly wound inside the coil through the inside of the toggle plate, and then the motor is started to rotate. When the motor rotates, the first roller is driven to rotate, and when the first roller rotates, the coil is driven to rotate. At the same time, the first roller drives the movable roller and the second roller to rotate through the crawler belt, and when the second roller rotates, the threaded rod is driven to rotate. When the threaded rod rotates, the movable shaft is driven to move parallel to the outside of the threaded rod through the threaded relationship between the threaded rod and the movable shaft, and then the raw material is driven to be evenly wound around the outside of the coil. When the tension needs to be adjusted, the threaded shaft is rotated by turning the rotating handle. By turning the handle, the movable rod can be driven to slide inside the slide rail, and the degree of adjustment required when the slide rail slides can be driven to move the movable roller. When the movable roller moves, when it moves outward, the movable block is driven down by the track, thereby driving the movable shaft and the toggle plate to descend. When the movable roller moves inward, the movable block is pulled upward by the tension spring, thereby driving the movable shaft and the toggle plate to move upward. The friction between the rubber protrusion inside the toggle plate and the raw material is increased to adjust its tension. Appropriate tension can ensure that the coil is tight and uniform, and reduce the gaps and irregularities inside the coil, which helps to improve the electrical and thermal properties of the coil, thereby enhancing the overall performance of the transformer.

When the threaded rod 12 rotates, it drives the threaded rod 12 to rotate. When the threaded rod 12 rotates, the threaded relationship between the threaded rod 12 and the movable shaft 15 drives the movable shaft 15 to move parallel to its outside, and then drives the raw material to be evenly wound around the outside of the coil 10. When it is necessary to adjust its tension, the threaded shaft 5 is rotated by rotating the rotating handle 4. The rotating handle 4 can drive the movable rod 6 to slide inside the slide rail 3. When the slide rail 3 slides, the degree of adjustment is required, and the movable roller 7 is driven to move.

When the motor 8 rotates, it drives the first roller 9 to rotate, and when the first roller 9 rotates, it drives the coil 10 to rotate. At the same time, the first roller 9 drives the movable roller 7 and the second roller 11 to rotate through the crawler. When the second roller 11 rotates, it drives the threaded rod 12 to rotate.
