摘要
CORC 电缆在核聚变项目运行过程中承受的巨大横向洛伦兹力可能会导致其载流能力不可逆转地下降。因此，研究电缆参数对其横向压缩性能的影响，并利用这些影响规律调整电缆参数以提高 CORC 电缆可承受的横向压缩载荷临界值尤为重要。使用上海超导公司生产的 4 毫米和 5 毫米宽的 HTS（高温超导）带分别制作了前端直径为 5.57 毫米的实心铜棒前端 CORC 电缆。实验结果表明，使用 5 毫米宽 HTS 带缠绕的 CORC 电缆比使用 4 毫米宽 HTS 带缠绕的电缆具有更大的临界横向压缩载荷。这表明，使用更宽的 HTS 带缠绕 CORC 电缆可有效改善其横向压缩性能。此外，还制作了实心铜棒成形 CORC 电缆和不锈钢螺旋管成形 CORC 电缆。通过横向压缩实验发现，实心铜棒成形器和不锈钢螺旋管成形器 CORC 电缆的临界横向压缩载荷分别为 130 kN/m 和 89 kN/m。这表明实心铜棒前 CORC 电缆具有更好的横向压缩性能。此外，我们还比较了平面压块和圆弧压块对 CORC 电缆横向压缩性能的影响，这些实验结果为使用 CORC 电缆制作线圈时选择线盘结构提供了依据。
Experimental research on the influence of HTS tape width and former type on the transverse compression performance of CORC cables
The huge transverse Lorentz force experienced by CORC cable during the operation of fusion projects may cause irreversible degradation of its current-carrying capacity. Therefore, it is particularly important to study the influence of cable parameters on their transverse compression performance, and use these influence laws to adjust cable parameters to improve the critical value of transverse compression load that CORC cables can withstand. Solid copper bar former CORC cables with a former diameter of 5.57 mm are produced using HTS (high temperature superconducting) tapes (manufactured by Shanghai Superconductor) of 4 mm and 5 mm width respectively. The experimental results show that the CORC cable wound with 5 mm wide HTS tape has a greater critical transverse compression load than the cable wound with 4 mm wide HTS tape. This indicates that using wider HTS tapes to wind CORC cables can effectively improve their transverse compression performance. A solid copper bar former CORC cable and a stainless steel spiral tube former CORC cable are also produced. Through transverse compression experiments, it is found that the critical transverse compression load of the solid copper bar former and the stainless steel spiral tube former CORC cable are 130 kN/m and 89 kN/m, respectively. This indicates that the solid copper bar former CORC cable has better transverse compression performance. In addition, we also compared the influences of flat and arc pressure blocks on the transverse compression performance of CORC cables, and this experimental results provided a basis for the selection of the bobbin structure when using CORC cables to make coils.
