Abstract
A superconducting energy storage inductor having two D-shaped coils with their flat sides being adjacent and facing one another. The coils are restrained from moving relative to one another and are immersed in a cryogenic fluid. The coils are connected in series and when provided with current, the resulting magnetic fields of the coils oppose one another.
Claims11
An improved energy storage inductor having a reduced external magnetic field, comprising:
- a) first and second D-shaped elongated superconducting coils;
- b) the flat sides of said D-shaped coils being adjacent and facing one another;
- c) the windings of said coils being oriented such that when supplied with electric current, the resulting magnetic fields of said first and second D-shaped coils oppose one another;
- d) containment means operable to support and restrain movement of said D-shaped coils relative to one another and including a central support member positioned between said first and second D-shaped coils and contacting at least the flat sides of said D-shaped coils;
- e) a belt arrangement positioned around and contacting the outer surface of said first and second D-shaped coils to restrain relative movement between said first and second D-shaped coils and said central support member;
- f) a cryogenic container;
- g) said first and second D-shaped coils being immersed in said cryogenic container.
