摘要 |
The present invention relates to a transformer with superconducting primary and secondary windings (1, 2), concentrically wound around a core limb (3), between which windings there is a concentric tubular space, the main channel, with insulation material (10) for insulation between the two windings. Cylindrical screens (11, 12) of a magnetic material with a high relative permeability are concentrically introduced into the insulation material at the two ends of the main channel. |
