Abstract
An electrical switchgear apparatus comprises a fixed frame, a circuit breaker movable in the fixed frame between a plugged-out position and a plugged-in position, a reversible plug-in and plug-out mechanism of the circuit breaker, a movable means for detecting an indexed position of the mechanism or of the circuit breaker, linked to a first electrical switch, and a movable means for detecting an indexed position (open or closed) of the main contact means of the circuit breaker linked to a second electrical switch. Each of the two switches comprises an input, a first output and a switching means able to take a first position in which it connects the input of the switch electrically to the first output of the switch, the switching means being kinematically linked to the corresponding detecting means, in such a way that the switching means is in its first position if and only if the corresponding detecting means is in its active position. The output of one of the switches is connected to the input of the other switch. A state indicating device is thus achieved with an input terminal, a first output terminal and means designed to electrically connect the input terminal and the first ou…
