Problems solved by technology
This winding can reduce the cost of the product, but because the upper and lower cake wires in the reverse section are prone to interference and kinking when the reverse section is wound, the winding process is poor, and it cannot be effectively used in the transformer coil

Embodiment Construction
[0015] like figure 1 As shown, in this embodiment, two parallel wires are used to wind a double continuous coil. The steps are as follows:
[0016] ① Firstly wind the lower cake 1 of the first reverse section with the lead-out line and the upper cake 1' of the first reverse section with the lead-out line on the winding machine at the same time;
[0017] ②At the same time, wind the lower cake 2 of the positive section and the upper cake 2' of the positive section;
[0018] ③ Simultaneously wind the temporary section of the upper cake 3' of the second reverse section and the temporary section of the lower cake 3 of the second reverse section, wherein the temporary section of the upper cake 3' of the second reverse section is directly wound outside the upper cake 2' of the main section, The temporary section of the lower cake 3 of the second reverse section utilizes a wedge-shaped pad composed of paper strips to wind above the upper cake 2' of the positive section;

The method includes steps: (1) winding lower cake of reversely wound disks and upper cake of reversely wound disks with outlet line by winder at same time; (2) winding lower cake of normally wound disks and upper cake of normally wound disks at same time; (3) winding temporarily wound disk of upper cake of reversely wound disks, and temporarily wound disk of lower cake of reversely wound disks at same time; the said temporarily wound disk of upper cake of reversely wound disks is wound outside upper cake of normally wound disks, and temporarily wound disk of lower cake of reversely wound disks is wound upside upper cake of normally wound disks; (4) turning temporarily wound disk of lower cake of reversely wound disks over to lower cake of reversely wound disks; (5) turning temporarily wound disk of upper cake of reversely wound disks over to upper cake of reversely wound disks. Repeating (2) to (5) finishes winding. The invention solves interference and kink between wires.
Description
technical field [0001] The invention belongs to the technical field of transformer windings, and in particular relates to a double continuous coil winding method wound by a plurality of parallel wires. Background technique [0002] At present, due to the large capacity and low voltage of some large and extra-large transformers, double-column spiral and continuous coils are widely used in the low-voltage coils. The height and requirements can adjust the longitudinal capacitance on the local line segment to improve the impact characteristics of the entire coil. In the design, it is required to adopt a coil structure type that combines the advantages of double-column spiral and continuous coil structures: double continuous structure. This winding can reduce product cost, but because the upper and lower cake wires in the reverse section tend to interfere and become kinked when the winding is wound in the reverse section, the winding process is poor, so it cannot be effectively u...
