Abstract: A monitoring system for a mechanically driven circuit breaker that includes fixed and moveable contacts, and a main actuator, wherein the moveable contact is selectively spaced from the fixed contact, and wherein the main actuator transitions the circuit breaker between states, the monitoring system comprising an actuation device; a sensor; and a processing unit. The actuation device applies a micro-motion to the actuator without the circuit breaker transitioning states; wherein the sensor acquires sensor data associated with the application of the micro-motion; wherein the sensor provides sensor data to the processing unit; and wherein the processing unit determines whether the circuit breaker has a fault using the sensor data.

Abstract: A switching apparatus including one or more electric poles. For each electric pole, the switching apparatus includes a first pole terminal, a second pole terminal, a ground terminal, and a plurality of fixed contacts spaced apart one from another. For each electric pole, the switching apparatus further includes a movable contact and a vacuum interrupter. The movable contact is reversibly movable about a corresponding rotation axis. The vacuum interrupter includes a movable arc contact reversibly movable along a corresponding translation axis. For each electric pole, the switching apparatus further includes a motion transmission mechanism operatively coupled to a contact shaft solidly coupled to the movable arc contact. The motion transmission mechanism is actuatable by the movable contact to cause a movement of said movable arc contact along said translation axis, when said movable contact moves about said rotation axis.

Abstract: A switching device including a switching unit with one or more electric poles having an insulating casing. The switching device is reversibly movable between an insertion position, at which said switching unit is electrically connected with an electric line, and a withdrawal position, at which said switching unit is electrically disconnected from said electric line. One or more actuating elements may be operatively coupleable with an actuating mechanism of a shutter device to operate one or more shutters of the shutter device during the movement of the switching device. The actuating elements may be fixed to the switching unit. At least one of the actuating elements includes a first mechanical connection with the insulating casing of at least one of the electric poles, and the insulating casing of at least one of the electric poles includes a second mechanical connection with at least one of the actuating elements.
