Abstract

La présente addition concerne des perfectionnements assurant la sécurité en cas de défaut sur le dispositif lui-même. L'appareil comprend un dispositif double 100 et 200 constituant deux ensembles de sécurité montés en parallèle sur le circuit à surveiller et sur le circuit de surveillance. Ils fonctionnent en sens inverse : lorsque l'élément de coupure du dispositif 100 ouvre le circuit (détection d'un défaut), le dispositif 200 ferme le circuit pour le même défaut. On a une sécurité négative et une sécurité positive. Application : sélection individuelle d'une machine par sécurité de blocage du défaut de terre par des diodes de type Zener.
