Abstract

L'invention concerne un court-circuiteur pour un dispositif de protection contre les arcs de lumière parasite, utilisé dans des systèmes de répartition d'énergie électrique. Ce court-circuiteur comprend un générateur de gaz et un élément court-circuiteur entraîné directement par le générateur de gaz. L'invention vise à empêcher les formations de tensions parasites produites par les gaz sur la ligne d'amorçage et par conséquent une destruction éventuelle du système électronique de commande, et à améliorer les propriétés de déclenchement du court-circuiteur. A cet effet, le court-circuiteur présente une première (22) et une deuxième chambre de pression (23). Le générateur de gaz (11) est placé dans la première chambre de pression (22) et une membrane à pression (24) est située sur le côté opposé du générateur de gaz (11). Cette membrane sépare la première chambre de pression (22) et la deuxième chambre de pression (23), et se brise en cas de dépassement d'une pression définie. L'élément court-circuiteur se présente sous la forme d'un piston (25) placé dans la deuxième chambre de pression (23).
