Title
(EN) CURRENT FEED-THROUGH FOR MEDIUM VOLTAGE CELL WITH SEALED METAL CASING
(FR) TRAVERSEE DE COURANT POUR CELLULE ELECTRIQUE MOYENNE TENSION A ENVELOPPE METALLIQUE HERMETIQUE
Abstract
(EN)
The invention concerns a plug-in feed-through for connecting an element such as a single-pole cable to a medium voltage electric cell with a sealed metal casing usually filled with gas. The feed-through comprises a body made of insulating material (13) run through by a solid connecting conductor (12) projecting from the body by its ends, and an annular flange (15) whereof the peripheral edge (15A) projects from the body to enable a welding for blocking the feed-through in a casing aperture. The annular flange comprises an internal edge (15B) embedded in the feed-through body, constituting a support for a semiconductor elastomer material layer (17) forming a shield controlling for the electric field. Said part is coated with an insulating elastomer material (16) separating it from the shielding semiconductor elastomer material layer (17), which is itself embedded in the elastomer material constituting the insulating body (13).

Traversée de courant, de type embrochable, pour le raccordement d'un élément, tel qu'un câble unipolaire, à une cellule électrique, de type moyenne tension, à enveloppe métallique hermétique et usuellement remplie de gaz. La traversée comporte un corps en matériau isolant (13), traversé par un élément conducteur massif de raccordement (12) saillant hors du corps par ses extrémités, ainsi qu'une bride annulaire (15) dont une bordure périphérique (15A) saille hors du corps pour permettre un soudage d'immobilisation de la traversée dans une ouverture d'enveloppe. La bride annulaire comporte une bordure interne (15B), noyée dans le corps de traversée, qui constitue un support pour une couche de matériau élastomère semi-conducteur (17) formant écran de contrôle de champ électrique. Cette partie est revêtue d'une couche isolante de matériau élastomère (16) qui le sépare de la couche de matériau élastomère semi-conducteur d'écran (17), elle-même noyée dans le matériau élastomère constituant le corps isolant (13).
