CA 2342422

An operation counter arrangement is provided for a circuit interrupter for opening a high- voltage circuit-isolating device. The operation counter arrangement responds to actual operations via response to a moving contact arrangement of the circuit interrupter. The operation counter arrangement is capable of retrofit to existing circuit interrupters via replacement of an exhaust control device of the circuit interrupter. In a preferred arrangement, a count of both the total number of operations and the number of operations since the most recent maintenance is provided.

Un compteur d'opérations est fourni pour un interrupteur de circuit pour ouvrir un dispositif isolant les circuits haute tension. Le compteur d'opérations réagit aux opérations réelles par la réponse à une disposition du contact de l'interrupteur de circuit. Le compteur d'opérations est capable de s'adapter aux interrupteurs de circuit actuels grâce au remplacement d'un dispositif de commande des gaz d'échappement de l'interrupteur de circuit. Dans une disposition préférée, un compte du nombre total d'opérations et du nombre d'opérations depuis l'entretien le plus récent est fourni.
