Description

Technical Field

[0001] The invention relates to the technical field of electrical engineering, and in particular to a high-temperature superconducting coil winding machine with adjustable tension and winding speed and a working principle thereof. Background Art

[0002] The superconducting tape used to wind the superconducting coil has a high width-to-thickness ratio, so when the superconducting tape is bent in the width direction, it will cause the superconducting tape to be damaged. Therefore, the winding machine needs to be adaptively designed according to the characteristics of the superconducting tape and superconducting coil to ensure smooth and complete winding work.

[0003] The existing winding machines have the following problems:

[0004] 1. The winding speed is not adjustable. Too fast a winding speed may cause the strip to break, while too low a winding speed may reduce the coil preparation efficiency.

[0005] 2. The tension is not adjustable and cannot be adapted to the winding process of superconducting coils of different sizes. If the added tension is too large relative to the current coil, it will cause the strip to be partially too tight, resulting in strip breakage or performance degradation; if the added tension is too small relative to the current coil, the turns of the superconducting coil may not be tight enough, resulting in uneven inter-turn resistivity of the wound superconducting coil.

[0006] 3. The horizontal height and angle cannot be adjusted, or the adjustment accuracy is limited. This may cause the pay-off reel, guide wheel and take-up reel of the superconducting tape to be not at the same horizontal height, resulting in the superconducting tape being bent or scratched during the coil winding process, thereby causing the critical current to decay. Summary of the invention

[0062] S3. According to the coil specifications to be wound, relevant parameters are set through the control system, such as the target number of turns, tension, and winding speed;

[0063] S4, the control system issues a command, the take-up motor drives the take-up drum to rotate, and the unwinding mechanism adjusts the unwinding speed in time according to the feedback information of the tension sensor and the encoder, so that the superconducting tape is wound on the winding skeleton with a stable tension; during the winding process, each guide wheel of the wire mechanism guides the tape to be accurately wound on the skeleton, ensuring that the winding coil is tightly wound between turns and the horizontal height is uniform;
