Abstract:
1. A Medium Voltage switch unit comprising an interruption unit and a disconnection unit, wherein the interruption unit comprises a first and a second interruption contact and a first drive unit which moves at least one of said first and second interruption contacts between a first position in which they are in electrical connection and a second position in which they are spaced apart, characterized in that said disconnection unit comprises a first and a second fixed disconnection contacts couplable and uncouplable with respective first and second movable disconnection contacts mounted on said interruption unit and electrically connected to said first interruption contact, said interruption unit being mechanically supported by a first fixed conductor and said second interruption contact being electrically connected to said first fixed conductor, the disconnection unit comprising a second drive unit which moves said interruption unit, relative to said first fixed conductor, between: a first disconnector position in which the first movable disconnection contact and the first fixed disconnection contact are coupled while the second movable disconnection contact is isolated from said second fixed disconnection contact; a second disconnector position in which said first and second movable disconnection contacts are isolated from said first and second fixed disconnection contacts; and a third disconnector position in which the second movable disconnection contact and the second fixed disconnection contact are coupled while the first movable disconnection contact is isolated from said first fixed disconnection contact.
