Abstract

Patentet beskriver en hovedbryteranordning for back-up-beskyttelse mot elektriske støt i jordbeskyttede forbruksinstallasjoner (TT-system ifølge IEC 60634), omfattende en beholder (1) med koplingsklemmer for nettledninger som fortrinnsvis er anordnet med to gjensidig termiske atskilte funksjonskamre som rommer et kontaktapparat (2) for utkoplingen av de ytre ledere LI, L2 og L3 og (4) for utkoplingen av den nøytrale leder N med tilhørende sperremekanisme (3), en summeringsstrømtransformator (5), en fortrinnsvis nettspenningsuavhengig elektronisk lager- og/eller forsterkerkrets (6) og et elektromekanisk relé eller en tyristor (7), hvor elektronikkretsen er koplet sammen med sekundærviklingen av summeringsstrømtransformatoren (5) og, når en feilstrøm overskrider en forhåndsbestemt verdi, aktiveres avledningsstrømsutløseren (8) via det elektromekaniske relé eller tyristoren (7) avhengig av nettspenningen, som kopler ut sperremekanismen (3) og dermed medfører åpningen av kontaktapparatet. Den elektroniske lager- og/eller forsterkerkrets (6) er dimensjonert på en slik måte at, uavhengig av feilstrømsnivået, utløsningstiden av hovedbryteranordningen alltid er høyere enn 0,2 sekunder og den totale utkoplingstid alltid er lavere enn 0,5 sekunder, for fellstrømmer på mer enn 10 ganger verdien på den nominelle feilstrøm.
