Abstract
360,288. Supply and conversion systems; transformers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Feb. 2, 1931, No. 3327. Convention date, Feb. 1, 1930. [Classes 38 (ii) and 38 (iv).] To avoid flame arc furnaces interfering with one another when being operated from a common transformer c through rectifiers b<1>, b2, the transformer has a number of secondary windings d<1>, d<2> corresponding to the number of furnaces a<1>, a<2> being supplied and these windings are subdivided and arranged on the core intermeshed. Further, in each furnace circuit the connections from the ends of the secondary winding to the anodes of the rectifier are through choking coils e<1> which are so interlinked that the successive half waves of opposite phase of the current magnetize their common iron core in the opposite sense. These chokes are so designed that should one furnace short-circuit they can absorb the full voltage of the secondary winding. A choke g is included in the primary circuit to stabilize the operations. A single rectifier having a suitable number of anodes may be used.
