Abstract

a. Système de coupure de courant comprenant un disjoncteur principal doté d'une caractéristique de retard et relie à une source de courant, un circuit destiné à limiter un courant anormal et des disjoncteurs secondaires reliés, d'une part, au circuit limiteur de courant et, d'autre part, à des circuits de charge secondaires. b. circuit limiteur de courant se compose d'un circuit parallèle comprenant une résistance à courant linéaire et une résistance à courant non linéaire, celle-ci étant un fusible permanent renfermant un métal alcalin ou du mercure comme substance destinée à limiter le courant. c. Application : disjoncteurs.
