Abstract

L'invention concerne des installations équipées d'interrupteurs sous vide pour couper des courants continus à basse tension de forte intensité, à la tension de la ligne d'alimentation du circuit, lorsque cette tension dépasse la chute de potentiel cathodique du matériau utilisé pour les contacts des interrupteurs. Selon l'invention, sont prévus au moins deux circuits en parallèle, le premier de ces circuits comportant au moins un interrupteur sous vide, et le second au moins deux interrupteurs sous vide, montés en série, ainsi que des moyens répondant à l'ouverture de l'interrupteur du premier circuit pour ouvrir simultanément les deux interrupteurs en série à un instant prédéterminé après l'ouverture de l'interrupteur sous vide du premier circuit Application à la coupure ou à la commutation de courants circulant dans les cellules électrolytiques sous une tension d'alimentation continue trop élevée.
