高温超导体 (HTS) 有望彻底改变风力发电机、直流电缆、粒子加速器和聚变能源设备等高功率应用。实用的高温超导电缆在恶劣的机械、电气和热条件下不得退化；具有简单、低电阻且可制造的电气接头；高热稳定性；以及快速检测热失控失控事件。我们设计并通过实验鉴定了真空压力浸渍、绝缘、部分换位、挤压和滚压成型 (VIPER) 电缆，该电缆首次同时满足所有这些要求。 VIPER 电缆临界电流在极端机电力水平、多次低温热循环和数十次失超瞬态事件下的数千次机械循环中保持稳定。 VIPER 电缆之间的电气接头简单、坚固且可拆卸。两个独立的集成光纤淬火检测器优于标准淬火检测方法。 VIPER 电缆代表了下一代能源生产和传输技术以及高温超导技术成熟度的一个重要里程碑。
High-temperature superconductors (HTS) promise to revolutionize high-power applications like wind generators, DC power cables, particle accelerators, and fusion energy devices. A practical HTS cable must not degrade under severe mechanical, electrical, and thermal conditions; have simple, low-resistance, and manufacturable electrical joints; high thermal stability; and rapid detection of thermal runaway quench events. We have designed and experimentally qualified a vacuum pressure impregnated, insulated, partially transposed, extruded, and roll-formed (VIPER) cable that simultaneously satisfies all of these requirements for the first time. VIPER cable critical currents are stable over thousands of mechanical cycles at extreme electromechanical force levels, multiple cryogenic thermal cycles, and dozens of quench-like transient events. Electrical joints between VIPER cables are simple, robust, and demountable. Two independent, integrated fiber-optic quench detectors outperform standard quench detection approaches. VIPER cable represents a key milestone in next-step energy generation and transmission technologies and in the maturity of HTS as a technology.
