[0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports and wharf CNC machinery and equipment. The commonly used windings inside dry-type transformers are foil coils. Foil coils are formed by winding one or more wires together. One type of coil, but the existing dry-type transformer foil coil has a simple structure and cannot be adjusted. After the coil is wound, it is easy to overlap the coils, resulting in the coils not being on the same plane, and the coils are not fixed when the coils are wound. Loose, the coil cooling effect is poor, reducing the performance of the device

The invention discloses a foil coil adjustable winding structure for a dry type transformer. The foil coil adjustable winding structure comprises a winding reel, wherein the two sides of the winding reel are fixedly provided with limiting plates, adjusting plates are movably arranged at the two sides of the outer surface of the winding reel, clamping grooves are formed on the outer surfaces of theupper ends of the adjusting plates, clamping plates are movably mounted on front and rear ends of the interiors of the clamping grooves, springs are movably mounted between the clamping plates and the clamping grooves, and mounting blocks are fixedly mounted on the upper and lower ends of the upper ends of the outer surfaces of the sides, away from the winding reel, of the limiting plates. The length of the winding reel is adjustable, and the winding reel is convenient for winding coils with different lengths. After winding, the coils can be pressed flat, the coils can be prevented from beingsuperimposed together, the flatness of the coil winding is improved, the head ends and the tail ends of the coils are fixed during winding, the coils are prevented from loosening, the contact area between the coils and the winding reel is reduced, the contact area with air is increased, and the heat dissipation efficiency of the coils is improved.
Description
technical field [0001] The invention relates to the field of winding structures, in particular to an adjustable winding structure of a dry-type transformer foil coil. Background technique [0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports and wharf CNC machinery and equipment. The commonly used windings inside dry-type transformers are foil coils. Foil coils are formed by winding one or more wires together. A type of coil, but the existing dry-type transformer foil coil has a simple structure and cannot be adjusted. After the coil is wound, it is easy to overlap the coils, resulting in the coils not being on the same plane, and the coils are not fixed when the coils are wound. If it is loose, the heat dissipation effect of the coil is poor, which reduces the performance of the device. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the presen...
