Control set for a cut of a line in case of overcurrent in this line and protection circuit breaker against an overcurrent in a line

摘要

Control set for a cut of a line (2) in case of overcurrent in this line (2), by transmission of an electrical control signal to a device (6) for maneuvering a switch (7) for cutting the line (2), the control assembly comprising: - an electromagnetic actuator (22, 24, 27, 31) whose one winding (22) to be connected in the line can produce a magnetic driving field and one of its equipment (27) mobile can move under the action of this magnetic driving field, from a waiting area to at least one firing zone, - an elastic return member (28) of the mobile equipment (27) towards the waiting area, in the opposite direction to the firing zone, characterized in that the control assembly comprises - a device (23, 25, 30, 32) for detecting a passage of the mobile equipment (27) from the waiting area to the firing zone, and - an electronic device (5) for monitoring the device (23, 25, 30, 32) of detection and control in the maneuvering device (6) to operate the switch (7) in the direction of a cut of the line (2) in the case where the detection device (23, 25, 30, 32) has detected the passage of the mobile equipment (27) from the waiting area to the firing zone.
