Abstract
A superconductive switch has a first layer of a superconductive coil wire wound around a shaft clockwise from the first end to the middle and counterclockwise from the middle to the second end. A second layer of the wire is wound around the first layer in identical fashion. A third layer of the wire is wound around the second layer counterclockwise from the first end to the middle and clockwise from the middle to the second end. An electrical heater is located between the first and second layers, and a stratum of electrical insulation, discrete from that of the coil wire, is located between the second and third layers.
Claims10
A superconductive switch comprising:
- a) a coil form including a generally cylindrical shaft having a generally longitudinally extending axis, first and second ends, a middle disposed generally equidistant from said ends, and clockwise and counterclockwise directions about said axis around said shaft;
- b) a first layer of an electrically-insulated, stabilized superconductive coil wire circumferentially wound around said shaft in said clockwise direction from said first end to said middle and in said counterclockwise direction from said middle to said second end;
- c) a second layer of said coil wire circumferentially wound around said first layer in said clockwise direction from said first end to said middle and in said counterclockwise direction from said middle to said second end;
- d) a third layer of said coil wire circumferentially wound around said second layer in said counterclockwise direction from said first end to said middle and in said clockwise direction from said middle to said second end;
- e) a first electrically-insulated, electrical heater disposed between said first and second layers;
- and
- f) a first stratum of electrical insulation discrete from that of said coil wire and disposed between said second and third layers.
