Title
(EN) A SUBSEA FUSE ASSEMBLY
(FR) ENSEMBLE FUSIBLE SOUS-MARIN
Abstract
(EN)
A subsea fuse assembly. The subsea fuse assembly comprises an enclosure (11) filled with a dielectric fluid(80) and provided with an equalization opening (22, 32), which is sealed with a flexible element (40). A first electric conductor (61) extends into the enclosure through a first lead-through (70) positioned in a wall (15) of the enclosure. A second electric conductor (62) is attached to an inner surface of a wall (14) of the enclosure. A fuse (50) is connected between the first electric conductor and the second electric conductor within the enclosure. A third electric conductor (63) extends outside the enclosure and is attached to an outer surface of a wall of the enclosure. An electrically conductive path is thus provided between the second electric conductor and the third electric conductor through the electrically conductive enclosure.

L'invention porte sur un ensemble fusible sous-marin. L'ensemble fusible sous-marin comprend une enceinte (11) remplie d'un fluide diélectrique (80) et pourvue d'une ouverture d'égalisation (22, 32), qui est scellée avec un élément souple (40). Un premier conducteur électrique (61) s'étend dans l'enceinte à travers une première traversée (70) positionnée dans une paroi (15) de l'enceinte. Un deuxième conducteur électrique (62) est fixé à une surface interne d'une paroi (14) de l'enceinte. Un fusible (50) est connecté entre le premier conducteur électrique et le deuxième conducteur électrique à l'intérieur de l'enceinte. Un troisième conducteur électrique (63) s'étend à l'extérieur de l'enceinte et est fixé à une surface extérieure d'une paroi de l'enceinte. Un trajet électroconducteur est ainsi prévu entre le deuxieme conducteur électrique et le troisième conducteur électrique à travers l'enceinte électriquement conductrice.
