摘要： A low-voltage circuit breaker includes at least one fixed contact, for each pole, which is electrically connected to a terminal for connection to an electric circuit, and a corresponding moving contact which is associable/separable with respect to the fixed contact by a rotation of the moving contact. The low-voltage circuit breaker further includes an arc chamber positioned in correspondence of the fixed contact, and a rotating contact supporting shaft common to all poles, which is functionally connected to an actuation mechanism of the circuit breaker, where the actuation mechanism includes a kinematic system operatively connected to an actuation lever for opening/closing operations and provided with opening springs and a tripping shaft for releasing the kinematic system and allowing its movement from a closed to an open position. The low-voltage circuit breaker further includes, for each pole, a quick acting trip device.

摘要： Described herein is a method for determining a presence of anomalous conditions in a switching apparatus installed in an electric line of an electric power distribution grid. The method includes a sequence of steps for adjusting a lumped-parameter model describing, for each electric phase, the behavior of the switching apparatus during the opening maneuvers of the switching apparatus. Simulation values provided by the lumped-parameter model are used for calculating estimation values indicative of the amounts of arc energy released by the breaking components of the switching apparatus during the opening maneuvers of the switching apparatus.
