Description
Stacked tape superconducting cables based on second-generation high-temperature superconducting REBCO tapes exhibit high current density and excellent mechanical performance under cryogenic conditions, showing significant potential for applications in power transmission systems of space solar power station. This study investigates the quench behavior of HTS REBCO stacked tape cables under various structural parameters and operational conditions through a combination of experimental and numerical analysis methods. A series of TSTC samples with different numbers of stacked layers and twisting angles were fabricated and tested experimentally in the liquid nitrogen temperature range. Key performance indicators, including the current-carrying capacity, minimum quench energy (MQE), and normal zone propagation velocity (NZPV), were analyzed in detail. Based on the experimental cable parameters, an electromagnetic-thermal coupled numerical model was developed, and its computational results were validated against experimental data. This study reveals the influence of structural parameters on the quench behavior of stacked tape cables, providing critical insights and design guidance for enhancing the operational stability and optimizing quench protection strategies of TSTC in space station and satellite applications.
