Abstract

Le dispositif comprend des modules de phase montés sur une base métallique (1) à l'intérieur de laquelle sont disposés des entraînements avec des verrous magnétiques (2, 3, 4), des arbres de synchronisation (6) et de verrouillage (7) et des contacts de blocs. Les modules de phase comprennent des diélectriques de support (9), avec des chambres à vide (10) disposées à l'intérieur, des bornes de contact (11, 12) et des diélectriques de traction (14). Les formes du diélectrique de traction (14) et du fragment tubulaire diélectrique immobile (16) forment un entrefer en labyrinthe entre les bornes de contact et la base, ce qui a pour effet d'augmenter l'intensité dans l'intervalle. Lors du fonctionnement du coupe-circuit des spirales conductrices élastiques (17) s'enroulent dans l'intervalle annulaire entre la borne (11) et la fiche de contact mobile (18), ce qui a pour effet de créer un contact à point multiples à conductivité élevée. Des systèmes magnétiques d'entraînement (2, 3) constituent deux composants en forme de coupe, faits d'un matériau à coercitivité élevée. Les bornes de contact sont fabriquées à partir d'un profil d'extrusion. Le générateur d'interruption d'alimentation manuelle se présente comme un système magnétique indépendant qui, lors de la déconnexion, génère une impulsion de courant, et qui est connecté à des bobines d'entraînement (4). Un indicateur à distance des positions de contact principales (19) est connecté au mécanisme d'arbre de synchronisation avec le raccordement souple ayant la forme d'un câble encapsulé. Des séparateurs de contact enfichables (23) sont fabriqués d'un alliage d'aluminium au moyen d'un processus d'extraction.
