Abstract

Abstract Translated from French A l'intérieur du tore (36) d'un transformateur différentiel (34) est agencé un shunt (38) magnétique intercalé entre les conducteurs actifs (14,16) du réseau alternatif, et constituant un circuit de fuite dont la réluctance magnétique détermine le seuil de déclenchement sur court-circuit. Le shunt (38) en forme de V ou de L est séparé du tore (36) par deux entrefers (e1,e2). Un relais de déclenchement (10) est piloté par l'enroulement secondaire (32) du transformateur. Application : interrupteurs ou disjoncteurs différentiels bipolaires et tétrapolaires. Inside the toroid (36) of a differential transformer (34) is arranged a magnetic shunt (38) interposed between the active conductors (14,16) of the alternating network, and constituting a leakage circuit whose magnetic reluctance determines the short-circuit trip threshold. The V or L-shaped shunt (38) is separated from the torus (36) by two air gaps (e1, e2). A trip relay (10) is controlled by the secondary winding (32) of the transformer. Application: two-pole and four-pole differential switches or circuit breakers.
