DEVICE FOR DETECTING RESETTING OF A CIRCUIT BREAKER, ACTUATOR OF A SEPARATING MECHANISM OF THE CIRCUIT BREAKER CONTACTS, ELECTRIC CIRCUIT BREAKER AND USE OF AN INDUCED CURRENT TO GENERATE A RESETTING INDICATION SIGNAL

摘要

The detection device (35) according to the invention makes it possible to detect resetting of an electric circuit breaker (10). The electric circuit breaker (10) comprises fixed (12) and moving (14) contacts, the moving contact (14) being capable of moving between an open position, in which the fixed and moving contacts (12, 14) are separated, and a closed position, in which the moving contact (14) is pressed against the fixed contact (12), a mechanism (16) for separating the contacts (12, 14), a lever (18) for resetting the mechanism (16) from the open position to the closed position of the moving contact (14), and an actuator (20) for actuating the separator mechanism (16), the actuator (20) including an electromagnetic coil and a core movable between an idle position and a working position in which the separating mechanism (16) is actuated, the coil being capable of causing the moving core to move from its idle position to its working position.;The detection device (35) comprises means to generate a resetting indication signal from an electric pulse, the 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.
