Abstract
Official abstract text for this publication.
A detection device that detects resetting of an electric circuit breaker. The electric circuit breaker comprises fixed and moving contacts, the moving contact being movable between an open position and a closed position, a mechanism for separating the contacts, a lever for resetting the mechanism from the open position to the closed position of the moving contact, and an actuator for actuating the separator mechanism, the actuator including an electromagnetic coil and a core movable between an idle position and a working position in which the separating mechanism is actuated, the coil causing the moving core to move from idle position to working position. The detection device may comprise means to generate a resetting indication signal from an electric pulse corresponding to an electric current induced in the coil by the movement of the moving core from its working position to its idle position during resetting of the circuit breaker.
First claim
Opening claim text (preview).
The invention claimed is: 1. A detection device for detecting resetting of a circuit breaker, the circuit breaker comprising fixed and movable contacts, wherein the movable contact is movable between an open position, in which the fixed and movable contacts are separated, and a closed position, in which the movable contact is pressed against the fixed contact, a mechanism for separating the contacts, a lever for resetting the mechanism from the open position to the closed position…
