Abstract

1,270,594. Transformers. ALLMANNA SVENSKA ELEKTRISKA A.B. 29 May, 1969 [30 May, 1968], No. 27182/69. Heading H1T. A transformer is provided with laminated magnetic plates 10 to divert leakage fluxes from frame or tank members &c., these plates being arranged between the end faces of the windings 7, 8 and supporting members 4, the ends of the plates adjacent the core yokes being supported in recesses in the yokes (at 16). The members 4 may be braced against pressure beams of the yokes. The plates 10a may be supplemented by plates 11 or may be L-shaped (as 10b). The plates 10 together with insulating members 6 and 9 provide support for the end faces of the windings. They may be of triangular, trapezoidal or parallelogram shape.
