Abstract
High-current, compact, flexible conductors containing high temperature superconducting (HTS) tapes and methods for making the same are described. The HTS tapes are arranged into a stack, a plurality of stacks are arranged to form a superstructure, and the superstructure is twisted about the cable axis to obtain a HTS cable. The HTS cables of the invention can be utilized in numerous applications such as cables employed to generate magnetic fields for degaussing and high current electric power transmission or distribution applications.
Claims80
A cable comprising:
- a plurality of high-temperature superconducting (HTS) tapes stacked substantially coplanar to a plane formed by the width and the length of individual HTS tapes to form an HTS stack, wherein a first HTS tape of the HTS stack is displaced a distance in the width direction from a second HTS tape positioned above the individual HTS tape in the HTS stack.
A method for making a cable, the method comprising:
- arranging a plurality of high-temperature superconducting (HTS) tapes substantially coplanar to a plane formed by the width and the length of individual HTS tapes to form an HTS stack,
- wherein a first HTS tape of the HTS stack is displaced a distance in the width direction from a second HTS tape positioned above the individual HTS tape in the HTS stack.
A cable employed to generate a magnetic field comprising:
- at least one cable comprising:
- a plurality of high-temperature superconducting (HTS) stacks arranged to form a superstructure, said HTS stacks comprising a plurality of HTS tapes substantially coplanar to a plane formed by the width and the length of individual HTS tapes, wherein a first HTS tape of the HTS stack is displaced a distance in the width direction from an HTS tape positioned above the individual HTS tape in the HTS stack,
- wherein at least one end of the plurality of HTS tapes is connected in series with an end of another HTS tape located in any one of the plurality of HTS stacks.
A cooling system comprising:
- a looped HTS cable;
- and
- a cooling system for maintaining the HTS cables in a superconducting state;
- the cooling system comprising a flow restrictor capable of dividing a flow of coolant into two different flow streams.
