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.

A termination structure of a cryogenic cable has a cryogenic-cable end portion (1) and a current-lead end portion (10) that are coupled to each other with a flexible conductor (5). Accordingly, any displacement in three-dimensional directions of the end portions that could occur due to thermal expansion and thermal contraction of the cryogenic cable and the current lead can be absorbed, and a sufficient current capacity can be ensured.

A multiphase superconducting cable connection structure includes a connection box (1) accommodating three conductor connects connecting a superconductor (201) of a cable core (102) of each phase extracted from a pair of 3-phase superconducting cables (100), a solid insulation member (2) fixed to an outer circumference of each conductor connect, and a metal flange fixing the solid insulation member (2) to the connection box (1). By fixing the metal flange (3) to the connection box (1) (a refrigerant vessel (11)), the conductor connect can be positioned and the conductor connector's movement caused as the cable core (102) thermally contracts can be reduced. The structure can help to position the conductor connect in the connection box and reliably hold it at a prescribed position.
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.
摘要:
A baking method for heating an object (an inner pipe 1, an outer pipe 2) having a vacuum layer formed therein to remove gas molecules occluded in the object, wherein the object itself is made to be a heat production element for heating. By making the baking object a heat production element, the object can be heated directly and the heating can be energy-efficient. Moreover, additional heating means such as a heater or gas is unnecessary, which enables simplification of a configuration of a baking device. Therefore, a baking method is obtained which enables energy-efficient heating and, in particular, uniform heating of a long or large object.
