The present invention concerns a method and a device for interlocking a disconnecting breaker. During interlocking of a single-poled or multiple-poled disconnecting breaker, the actuator of the breaker is first interlocked both electrically and mechanically. When the breaker is in the open position, the distance between the contacts of the breaker comprises the conductor spacing for the isolation function. The electrical and mechanical interlocking of the actuator is indicated both electrically and mechanically. Subsequently, the link system of the breaker is mechanically interlocked. The link system is locked in the interlocked position. Interlocking of the link system is indicated by at least one indicator. Interlocking of the actuator of the breaker can be controlled manually via a key- and lock device, or remotely.

La présente invention concerne un procédé et un dispositif d'interverrouillage d'un disjoncteur. Au cous de l'interverrouillage d'un disjoncteur unipolaire ou multipolaire, l'actionneur du disjoncteur est d'abord interverrouillé à la fois électriquement et mécaniquement. Lorsque le disjoncteur est en position ouverte, la distance entre ses contacts comprend l'écartement entre conducteurs aux fins d'isolation. L'interverrouillage électrique et mécanique de l'actionneur est indiqué aussi bien électriquement que mécaniquement. Ensuite, le système de liaison du disjoncteur est verrouillée mécaniquement. Ce système est verrouillé dans la position d'interverrouillage. L'interverrouillage dudit système est indiqué par au moins un indicateur. L'interverrouillage de l'actionneur du disjoncteur peut être commandé manuellement au moyen d'un dispositif verrou à clé, ou à distance.
