Abstract

A medium and/or high-voltage circuit breaker, comprising an insulating casing inside which there is at least one interruption chamber which contains at least one fixed contact and at least one moving contact and a dielectric fluid for quenching electric arcs, the particularity of which is the fact that the dielectric fluid for quenching electric arcs comprises a fluoridized dielectric fluid which contains dissolved oxygen and that it comprises at least one first active filter located in the volume occupied by the fluoridized dielectric fluid, the first active filter being suitable to neutralize the chemically reactive species that originate from the decomposition/recombination of the fluoridized dielectric fluid following an electric arc.
