Abstract:Under the overcurrent conditions that cause a sharp increase in the temperature of superconducting cables, the superconducting materials in them will lose their superconducting properties in a short period of time. In this study, the fault overcurrent condition of HTS cable is taken as the example, and the electrothermal characteristics of the HTS cable are analyzed during the transient fault condition and the recovery process. In the heat transfer model, combined with the electrical and thermal characteristics of REBCO tapes, the temperature performance is iteratively calculated considering the influence between different layers of the HTS cable.
