1,133,305. Transformers. WESTING- HOUSE ELECTRIC CORP. 23 May, 1967 [28 July, 1966], No. 23827/67. Heading H1T. A disc coil winding comprising disc coils 22, 24 &c. (Fig. 1), having interleaved turns, each conductor comprising a plurality of axially (and if desired, radially) disposed conductive strands providing a corresponding number of axial layers 38, 40 in the discs, the straws (e.g. A and B), being transposed in at least one coil (e.g. in the end coils and those having tappings and hence subject to distortion in the leakage flux pattern), by connections (see Fig. 6A) between the inner and outer turns of the coil giving 180 degrees rotational symmetry between those turns. The coils may be axially spaced to provide cooling ducts 34, and the transformer may be filled with sulphur hexafluoride. |
