CA 2744979

An interlock assembly (90) for a bypass isolation open or closed transition ATS assembly (10) is disclosed. The interlock assembly (90) ensures that a switch assembly (14, 16) being worked upon and/or be-ing inserted is in a neutral configuration, i.e. the switch assembly (14, 16) is not engaging a power source. The interlock assembly (90) is, preferably, an electrical inter-lock having a control system (18) structured to configure the switch assemblies (14, 16) and to monitor the config-uration of the switch assemblies (14, 16). That is, the switch assemblies (14, 16) each include a power operat-ed, conductive, movable contact arm (30, 60). The posi-tion of each contact arm (30, 60) is controlled, and moni-tored by, the control system (18) which controls the sin-gle actuator for each contact arm (30, 60).

La présente invention concerne un ensemble à interblocage (90) destiné à un ensemble de commutateurs de transfert automatiques ou "ATS" (Automatic Transfer Switch) à transition d'isolation de dérivation ouverte ou fermée. L'ensemble d'interblocage (90) garantit qu'un ensemble de commutateurs (14, 16) sur lesquels on est en cours d'intervention et/ou que l'on est en train d'insérer est en configuration neutre, c'est-à-dire que l'ensemble de commutateurs (14, 16) ne touche aucune source électrique. L'ensemble d'interblocage (90) est de préférence un interblocage électrique pourvu d'un système de commande (18) structuré de façon à configurer les ensembles de commutateurs (14, 16) et à en surveiller la configuration. En l'occurrence, chaque ensemble de commutateurs (14, 16) comporte un bras de contact (30, 60) mobile et électroconducteur motorisé. La position de chaque bras de contact (30, 60) est commandée et surveillée par le système de commande (18) qui commande l'unique actionneur de chaque bras de contact (30, 60).
