US INTERCONNECT MEMBER FOR A TRANSFORMER COIL, COIL HAVING SUCH AN ORGAN, ACTIVE PART, AND TRANSFORMER COMPRISING SUCH AN ACTIVE PART.

摘要

The insert (20) for isolating two windings belonging to a coil comprises a generally annular plate (21) and several spacers (31-36) placed at least on one of the faces of the plate (21) so as to define channels for the flow of a dielectric fluid. The plate (21) and the spacers (31-36) are made of a polyaramid. So-called main spacers (31-34) define at least one main channel (51-53), the or each main channel (51-53) having many changes in direction and extending along a main direction (Y23-Y24) which join two opposed edges (23, 24) of the plate (21). The main spacers (31-34) are one-piece spacers and extend over a length (L31, L32, L33, L34) equal to or greater than 40% of the length (L21) of the plate (21), the lengths being measured parallel to the main direction (Y23-Y24).
