Modular device for clamping and positioning power transformer windings, particularly for a dry-type transformer with resin-encapsulated windings

摘要

A modular device for clamping the windings of a transformer in which two parallel sides (2, 3) of an elongate base block, extending downwards to form an elongate lower housing open at its ends, have identical upper external toothings and lower internal toothings (7, 8, 9, 10), the distance W2 between the two opposite upper toothings (7, 8) being equal to the distance W2 between the two facing lower toothings (9, 10) so that a plurality of said base blocks can be interlocked together in stacked relationship, possibly in staggered positions in the direction of length, and a winding guide element (19) and a bolt-carrying element (11) having the same transverse profile as the base block, with identical toothings, can also be interlocked in stacked relationship to a base block.
