In this paper, a transformer type superconducting fault current limiter (SFCL) with two isolated secondary windings was fabricated to increase the current limiting capacity. As the magnetization current increased due to the large transient fault current immediately after the fault, the magnetization force variation, the operating range of the flux linkage, and the voltage region variation were compared at fault angles of 0° and 90°, respectively. The short-circuit test analyzed the current limiting operation, power consumption, and energy consumption characteristics according to the fault angle immediately after the fault occurrence. The results showed that the fault angle of 0° could limit the fault current much more than the fault angle of 90°. In addition, it was confirmed that the magnetization force variation, the operating range of the flux linkage, and the voltage induced in the primary winding were all much larger at the fault angle of 0° than at the fault angle of 90°.

具有两个隔离次级绕组的变压器型SFCL的故障角引起的磁化特性

在本文中，制造了具有两个隔离次级绕组的变压器型超导故障限流器 (SFCL)，以增加限流能力。由于故障后立即有较大的瞬态故障电流导致磁化电流增加，因此分别比较了故障角为0°和90°时的磁化力变化、磁链工作范围和电压区域变化。短路试验根据故障发生后立即的故障角度分析了限流动作、功耗和能耗特性。结果表明，0°的故障角比90°的故障角对故障电流的限制要大得多。此外，证实了磁化力的变化，
