中文摘要：

对两根2.2 m长YBCO涂层导体绕制的冷绝缘高温超导导体模型进行短路实验。实验在77.3 K的液氮环境进行,短路电流25 k A,时长2 s。对电缆温升和恢复进行实验研究,与仿真模拟结果进行比较,实验值和仿真模拟值吻合得很好。

英文摘要：

Two 2. 2 m long cold dielectric（ CD） model conductors were fabricated by YBCO coated conductors（ YBCO CC）. The short-circuit test was performed with current 25 k A durations of 2 s in liquid nitrogen（ LN2） temperature of 77. 3 K. The temperature rise and recovery of cable conductors were simultaneously measured during the fault test. Additionally,the temperature rise and recovery were simulated during and after fault accident,respectively. The experimental results are agreement with the simulated results cable.
