摘要

圆芯导体（CORC）电缆由多层螺旋状缠绕的第二代高温超导（HTS）带制成。由于其制备工艺简单、载流量大、交流损耗低，它是最有前途的 HTS 电缆。CORC 电缆具有屏蔽电流，在电磁场加载过程中会导致场误差和中心磁场漂移。此外，磁带缠绕模式和缠绕角度的微小变化会导致 ReBCO 磁带上的电流分布发生变化，从而造成交流损耗的差异。本文讨论了屏蔽对 CORC 电缆电磁特性和中心磁场的影响，并研究了不同绕组模式和角度对磁化损耗的影响。研究结果表明，屏蔽电流会造成磁化损耗，而绕组结构对这些损耗有显著影响。调整绕组角度可以降低磁化损耗，改善电缆性能。

Influence of ReBCO tape winding mode on the magnetization loss of CORC cable under the shielding current effect

Conductor on round core (CORC) cable is made of second-generation high-temperature superconducting (HTS) tapes wound in multi-layer spirals. It is the most promising HTS cable due to its simple preparation process, high current-carrying capacity and low AC loss. CORC cable has shielding currents that cause field errors and centre magnetic field drift during electromagnetic field loading. Additionally, small changes in the winding mode and winding angle of the tape will lead to changes in the current distribution on the ReBCO tape, which results in differences in AC loss. In this paper, the influence of shielding on the electromagnetic characteristics and central magnetic field of CORC cable is discussed, and the influence of different winding modes and angles on the magnetization loss is investigated. The results of the study show that the shielding current will cause magnetization loss, and the winding structure has a significant effect on these losses. Adjusting the winding angle can reduce the magnetization loss and improve the cable performance.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
