电阻式超导故障限流器（R-SFCLs）利用稀土钡铜氧化物（REBCO）带来限制故障电流。为了平衡恢复性能和限流性能，提出了一种多孔稳定的REBCO带。实验结果表明，将多孔稳定剂与REBCO胶带和绝缘环氧树脂混合使用可将恢复时间缩短至25%。然而，这种恢复性能改善的潜在机制尚不清楚。本研究的目的是了解这些机制。为此，提出了一个气膜崩塌模型来阐明绝缘环氧树脂对气膜崩塌的影响。该模型表明，当液氮（LN2）与绝缘环氧树脂接触时，会引起绝缘环氧树脂表面温度的迅速下降，导致气膜的坍塌。此外，提出了一种液体保留模型来研究多孔稳定剂的影响。该模型表明，如果多孔稳定剂能够截留LN2，则可以通过截留LN2的蒸发来实现实验中观察到的等效热流密度。
Resistive-type superconducting fault current limiters (R-SFCLs) utilizing rare-earth barium copper oxide (REBCO) tapes have been developed to limit fault currents. To balance recovery and current-limiting performances, a porous-stabilized REBCO tape was proposed. The experimental results showed that using a porous stabilizer with the REBCO tape and insulating epoxy reduced recovery time to 25%. However, the underlying mechanisms of this improvement in recovery performance are not yet clear. The aim of the present study is to understand these mechanisms. To do so, a vapor-film-collapse model was proposed to clarify the impact of the insulating epoxy on vapor film collapse. This model suggests that when liquid nitrogen (LN2) comes into contact with the insulating epoxy, it causes a rapid decrease in the temperature of the insulating epoxy surface, leading to the collapse of the vapor film. Additionally, a liquid-retention model was proposed to investigate the effect of the porous stabilizer. This model indicates that if the porous stabilizer can retain LN2, the equivalent heat flux observed in experiments can be achieved through evaporation of the retained LN2.
