Abstract

1443207 Coil BBC BROWN BOVERI & CO Ltd 12 Oct 1973 [16 Oct 1972] 47806/73 Heading H1P An impregnated coil having at least one cooling duct, is made by incorporating an insert in the coil during winding, the insert corresponding to the shape of the duct, winding and impregnating the coil and removing the insert by a chemical or thermal process. The inserts may be removed before or after curing. The coil is wound on support tubes 5, 6 of compressed glass fibre with compressed glass fibre edge plates 3, 4 having radial slots 16. Superconducting wires 11 are wound about the tubes with intermediate layers 12 of glass fibre fabric and inserts 17 of Wood's metal inserted through slots 16, the inserts being circumferentially separated by heat-conductive bands 19 of a mesh or fabric made from insulated copper or aluminium wires. The glass fibre fabric may be dusted with graphite or metal powder optionally containing a binder or coated with metal by spraying or evaporation to make the fabric heat-conductive. Alternatively the powder may be introduced with the impregnant. The fabric may be impregnated prior to winding with dried but uncured resin or the resin may be cured. A glass-fibre fabric 7 is wound around the coil and the coil placed in mould 1, 2, 8, 9. The mould is evacuated by pipe 15 and impregnated with epoxy resin at 13. The inserts 17 are removed by melting them with hot nitrogen to leave coolant channels 18, Fig. 3. In another embodiment (Figs. 4 to 6, not shown) the superconductors are rectangular in cross-section and provided with an insulating layer. Intermediate layers of glass fibre are provided between successive layers of superconductors. A superconductive quadrupole winding may also be made using the method (Figs. 7 to 9 not shown).
