Abstract

387,472. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and WHITAKER, F. P., 237, Clifton Road, Rugby. Dec. 15, 1931, No. 34753. [Class 38 (ii).] A transformer for supplying the anodes of a rectifier with 12-phase currents comprises primary and secondary windings divided into two groups, the primary windings a, b being similar and connected in parallel, while the groups of secondary windings c, d are each in 6-phase relation, the two groups being displaced in phase with regard to each other to produce 12 phases 1 . . 12. The neutral points of the secondaries are connected together by means of interphase transformers e, f, g. The two groups of windings may either be arranged as two separate transformers, or they may be wound on a single core.
