POWER LEAD AND POWER TRANSMISSION SYSTEM WITH THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To reduce the intrusion of heat into a super-conductive feeder cable and to restrict the Joule's heat to be generated when electrifying in a power lead which connects between a super-conductive feeder cable and a trolley line (wire). <P>SOLUTION: The power lead (20) connects between the super-conductive feeder cable (50) cooled by a refrigerant (26) and the trolley line (wire) (80). The power lead (20) includes: a conductor part (22) having a hollow part (21); a bar-like member (23) provided with a slit part (25) in the tip thereof; and a seal member (24) which seals the hollow part from a super-conductive feeder cable side and holds the bar-like member from the periphery thereof freely to move along the longitudinal direction. The bar-like member is formed from a material having a linear thermal expansion ratio smaller than that of the conductor part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
