Abstract
In order to make it possible to produce superconducting coils with small overall height, they are made from a plurality of coil subunits, optionally with a plurality of layers for each coil subunit, in particular in the case of the low-voltage coil of a transformer. The coil subunits contain as electrical conductor a high-temperature superconductor, around which a fibrous glass is spun and which is embedded in a glass-fiber reinforced epoxy resin or in a plastic. The coil subunits are placed around a transformer core in a cryostat.
Claims17
A superconducting coil
- a) having at least one layer of winding elements made of a superconductor,
- b) in which the superconductor is enclosed by at least one electrically insulating fiber and
- c) is embedded in an electrically insulating, fiber-reinforced epoxy resin or in a plastic, wherein
- d) the superconductor is a high-temperature superconductor, and
- e) the coil has at least two coil subunits with high-temperature superconductors, which are electrically connected in series by at least one normal conductor.
