Abstract

La bobine annulaire (27) selon l'invention a une section droite de forme générale carrée ou légèrement rectangulaire et comprend une coquille de résine isolante (29) encapsulant un ensemble (28) de spires en série (30) formée par un conducteur filaire (2) à gainage diélectrique (3), bobiné en couches de spires longitudinales ou radiales, dont le nombre est déterminé en fonction de l'épaisseur du gainage (3) de façon que la tension entre deux spires jointives mais les plus éloignées électriquement n'excède pas, pour une tension d'entrée donnée quelconque de la bobine, une valeur de tension disruptive (Td) fournie par application dans l'air de la loi de Paschen audit conducteur gainé. On peut alors notamment construire des enroulements complets (38) pour transformateurs secs par simple empilage de bobines élémentaires de ce type, tout en conservant l'air comme milieu diélectrique dans les espaces inter-spires.
