Background technique [0002] High-temperature superconductors can achieve superconducting properties at the temperature of liquid nitrogen, showing great application potential of high-temperature superconductors, among which superconducting magnets are an important application direction of high-temperature superconductors. The development of superconducting magnets makes it easier to obtain ultra-high magnetic fields than before, and can reach magnetic field strengths that cannot be achieved by copper coils, which has good application prospects. [0003] At present, there are three main types of high-temperature superconductors used to wind superconducting magnets, namely Bi2212 round wire, Bi2223 strip and RE123 strip.

Problems solved by technology

[0004] However, since high-temperature superconducting materials are new materials, there is no general-purpose winding equipment at present, and in order to ensure that the superconducting magnet generates a stable magnetic field in the actual use process, the tension of the superconducting tape is required to be consistent during the winding process.
