    摘要： 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 one of said interruption contacts between a first position in which they are in electrical connection and a second position in which they are spaced apart. The disconnection unit comprises a first and a second fixed disconnection contacts couplable and uncouplable with respective first and second movable disconnection contacts mounted on the interruption unit and electrically connected to the first interruption contact. The interruption unit is mechanically supported by a first fixed conductor and the second interruption contact is electrically connected to said first fixed conductor. The disconnection unit comprises a second drive unit which moves the interruption unit, relative to said first 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 the first and second movable disconnection contacts are isolated from the 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.

    摘要： A support assembly is for an electrical system. The electrical system includes a network protector and a number of disconnect switches coupled to the network protector. The support assembly includes: an insulative mounting member coupled to each of the disconnect switches; a number of base assemblies each including a housing assembly and a stand assembly disposed on the housing assembly, the housing assembly being coupled to the insulative mounting member; and a lifting apparatus disposed on each of the base assemblies. The lifting apparatus moves each of the insulative mounting member and the housing assembly in a direction transverse to the stand assembly.
