摘要： A superconducting cable has a plurality of superconducting wires wound around a core material (former) in a multilayered manner. The superconducting wires employ a twisted filament type superconducting wire having spiral superconducting filaments and an untwisted filament type superconducting wire having straight superconducting filaments. The layer in which an applied magnetic field is large and of which the low loss effect is expected is formed of twisted filament type superconducting wires, and the other layers are formed using the untwisted filament type superconducting wires; thus the AC loss can be reduced effectively. Thus, in the superconducting cable, the AC loss can be effectively reduced while a degradation of the current characteristics and the increase of cost are suppressed.

摘要： A method of operating a superconducting cable using a conductor cooled by a refrigerant to transmit electric power causes a change in the refrigerant temperature to change the transmission capacity of a superconducting cable(110, 120, 130). Since superconducting materials are capable of increasing the value of their critical current as the temperature decreases, the refrigerant temperature may be changed to change the transmission capacity of the superconducting cable (110, 120, 130) without overdesigning of cabling or an additional cable.

摘要： A superconducting cable according to the present invention includes a former, a superconducting conductor layer formed around the outer circumference of the former, an electric insulating layer formed around the outer circumference of the conductor layer, a shield layer formed around the outer circumferential of the insulating layer, and a normal-conducting metal layer formed between the insulating layer and the shield layer. The normal-conducting metal layer existing inside shield layer has an inductance greater than that of the shield layer, which can suppress a rise in temperature in the event of accidents such as short-circuits, and also can reduce AC losses since currents flow through shield layer during the passage of normal currents.

摘要： A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and a shield connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.

摘要： A phase separation jig (100) for a superconducting cable includes: a cable holder (10) maintaining each core (80) of a multi-core superconducting cable (2) in a predetermined tolerable bending manner; and a coupler (20, 30) holding the cable holder (10) for each core (80) at a predetermined spacing with each other. Each core (80) is spaced apart from each other and maintained in a tolerable bending manner by the holder (10). Accordingly, a phase separation structure can be obtained which can regulate deformation of the cable and prevent abnormal deformation even for a superconducting cable.
