摘要:
A phase split structure (150) of a superconducting cable includes three cable cores (102) each having a shield layer (203) provided around a superconductor (201), a splitter box (1) housing the three cable cores (102) extending from an assembly portion (110) where the three cable cores (102) are assembled into the cable, in a state in which the cable cores (102) are spaced apart from each other, and an electrically-conductive connecting portion (2) connecting respective shield layers of the cable cores (102) to each other within the splitter box (1). In this way, occurrence of a large magnetic field outside the cable cores (102) can effectively be reduced.

摘要:
The present invention provides a terminal structure of a superconducting cable (100) including a cable core (102) having a superconducting shield layer (203) and an electrical insulation layer (202). The superconducting shield layer (203) has a radially outer portion provided with by a connection electrode (1) and the superconducting shield layer (203) and the connection electrode (1) are connected together with a low melting solder (5). The connection electrode (1) has a ground wire (3) connected thereto to ground the superconducting shield layer (203). For a multiphase cable including a plurality of cable cores (102), connection electrodes (1) are linked by a conductive coupling member (2) to short circuit superconducting shield layers (203). The superconducting shield layer (203) can be grounded without impaired insulating property of the electrical insulation layer.

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.
