Title (EN) SURGE ARRESTER
(FR) PROTECTION CONTRE LES SURTENSIONS
Abstract:
(EN) A failure indicator device for a surge arrester (2) employs a conventional explosive disconnector (10). Operation of the disconnector (10) due to earth fault current passing through the arrester (2) causes an arc to be formed. Movement of the disconnector (10) away from the arrester (2) is guided and limited by a support arrangement (18, 20) that subsequently provides a solid and permanent conductive path to earth (6) from the arrester terminal (12), thus extinguishing the arc.
(FR) Dispositif indicateur de défaut destiné à un dispositif de protection contre les surtensions (2) employant un sectionneur par explosion classique (10). L'activation du sectionneur (10) en cas de passage de courant de défaut à la terre par le dispositif de protection contre les surtensions (2) provoque la formation d'un arc. Le déplacement du déconnecteur (10) s'éloignant du dispositif de protection (2) est guidé et limité par un dispositif de support (18, 20) qui constitue par la suite une voie de passage à la terre solide et permanente (6) depuis la borne du dispositif de protection (12), éliminant ainsi l'arc.
