Abstract
1,213,365. Transformers. B. S. & W. WHITELEY Ltd. 5 Nov., 1969 [8 Nov., 1968], No. 52961/68. Heading HIT. A transformer H.V. winding 11 is insulated from L.V. winding 10 by a plurality of concentric pressboard cylinders 12 with longitudinal corrugations 14 which are in the same sense and are radially aligned from one cylinder to the next. The cylinders are spaced to provide ducts 22 for cooling oil by longitudinal sticks 15 of laminated or resin bonded pressboard. Each stick 15 has a rib 16 and a channel 17 to fit re-entrant and projecting surfaces respectively of aligned corrugations, thus providing positive lateral location of the sticks. Further radially aligned sticks 18, 19 space the cylinders from the windings. The cylinders are made from one or more pieces, glued with a thermosetting adhesive at scarf joints 13. In an alternative embodiment, the corrugations (23) are V-shaped and the sticks (24) are of pressboard and V-shaped with the two arms of equal length.
