摘要
基于均流原则,提出了一种700 MVA/20 kV单相高载流低损耗高温超导电缆结构,可应用大电流、中低压应用场景。通过解析法和有限元法对提出的高温超导电缆和常规结构超导电缆的电磁特性和磁滞损耗进行分析。结果表明,额定运行时所提出的电缆结构损耗比常规结构超导电缆降低了69.9%,从而具备更高的的载流能力和带材利用率。
In this paper, a 700 MVA/20 kV single-phase HTS cable with high current-carrying rate and low-loss was proposed based on the principle of uniform current, which could be applied to high-current and mid-/low-voltage scenarios. The electromagnetic characteristics and hysteresis losses of the proposed HTS cable and the conventional HTS cable were analyzed by analytical and finite element methods. The results show that the proposed HTS cable has 69.9% lower losses than the conventional one at rated operation resulting in higher current-carrying capacity and tapes utilization.
