摘要

目前,在从低压级到最高传输电压的断路器中,都使用触点来承载电流,并使用触点开路时形成的电弧来断开电流。在各种可能但很少使用的替代原理中,自从发现高T/sub /超导体(HTSCs)以来,超导和正常导电状态之间的转变得到了新的关注。本文评估了用这种超导体制作阻性限流器的技术可能性和存在的问题。基于HTSC样品的实验研究结果,对有效HTSC限制器在电网中的行为进行了模拟。假设导体为均匀导体,对不同临界电流密度的导体计算超过临界电流初始化的自猝灭。此外,还讨论了沿导体的不均匀性、电流脉冲触发、瞬态过电压和并联元件的影响等问题。

High temperature superconductors as current limiters-an alternative to contacts and arcs in circuit breakers?
Nowadays in circuit breakers from the low voltage level to the highest transmission voltages, contacts to carry the current and arcs established at contact opening to break it are utilized. Of the various possible but scarcely used alternatives to this principle, the transition between the superconducting and normal-conducting state has gained new attention since the high T/sub c/ superconductors (HTSCs) have been discovered. This paper assesses the technical possibilities and problems of resistive current limiters with such superconductors. Based on results of experimental investigations of HTSC samples, simulations of the behavior of fictive HTSC limiters in electrical power networks are carried out. Assuming a homogeneous conductor, the self-quench initialized by exceeding the critical current is calculated for conductors with different critical current densities. Furthermore, questions of inhomogeneity along the conductor, current pulse triggering, transient overvoltages and the effect of parallel elements are discussed.
