摘要 本文基于第二代高温超导带材的结构及特性,提出一种高温超导故障限流电缆的概念。该电缆使用不锈钢加强的第二代超导带材,并以不锈钢丝绞线作为骨架。通过对带材超导态下低电阻和失超时高电阻特点的利用,实现超导限流电缆的限流特性。本文在实验研究不锈钢带材的失超电阻及限流特性的基础上,对限流电缆进行结构设计并制作了限流样缆。通过对电缆试样进行冲击试验及数值仿真,对其在短路故障时的限流特性及失超恢复特性进行分析。结果显示,该电缆可以有效地降低故障电流,在实际工程应用中可以实现电能传输和限流的双重功能。

Abstract:This paper presents a high temperature superconducting (HTS) fault current-limiting cable (SFCLC) based on the structure and characteristics of the second-generation (2G) HTS tapes. The cable uses a kind of stainless steel reinforced 2G tapes and the former is strand consisting of stainless-steel wires. The current limiting characteristics of this cable are realized through the use of the characteristics of 2G tapes with very low resistance at superconducting and high resistance at normal states. After quench resistance and current limiting characteristics of stainless-steel tapes being measured and analyzed, the main geometrical parameters of the SFCLC are designed and sample SFCLC is prepared. Fault current limiting tests and numerical simulation of the sample cable are performed to obtain the current limiting and quench recovery characteristics in the case of a short-circuit fault current exists, respectively. The results show that the cable can effectively reduce the fault current, which means it can realize the dual functions of electric energy transmission and current limitation during faults in practical engineering applications.
