摘要： 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 vacuum interrupter includes a fixed arc contact and a movable arc contact reversibly movable along a corresponding translation axis between a coupled position with the fixed arc contact and an uncoupled position from the fixed arc contact. For each electric pole, the switching apparatus further includes a motion transmission mechanism operatively coupled to a contact shaft 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.

摘要： 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, and a ground terminal. The switching apparatus further includes a plurality of fixed contacts spaced apart one from another, a movable contact, which is reversibly movable about a corresponding rotation axis according to opposite first and second rotation directions, so that said movable contact can be coupled to or uncoupled from one or more of the above-mentioned fixed contacts, a vacuum interrupter including a vacuum chamber, in which a fixed arc contact and a movable arc contact are enclosed and can be coupled or separated, and a motion transmission mechanism operatively coupled to the movable arc contact of said vacuum interrupter.

摘要： 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.
