Abstract: A switchgear which includes at least one three-position disconnector arranged in a gas-tight space of a frame. Each phase of the disconnector includes first, second, and third fixed contacts and a moving contact. The first fixed contact is directly connected to a main busbar, so that the conductive main circuit has shorter wiring, saving floor space, and conductor materials. An outer surface of the moving contact is provided with a slot extending in an axial direction to accommodate rolling elements, which guide the moving contact to move through the second fixed contact and prevent it from rotating. The moving contact is provided with grooves, which accommodate contact pieces to realize connection with the corresponding fixed contact. The moving contact of each disconnector is coupled to the same drive shaft so that it is connected to an external operating mechanism via only one sealing point on the frame.

Abstract: A bus bar system and an apparatus for bus bar connection. The bus bar system includes a plurality of members, and a component configured to couple the plurality of members to form a connection portion having a cavity. Further, the component is arranged in the cavity such that it is possible to achieve a significant reduction in the number of parts for bus bar connection without requiring a large number of screws or electric field shieldings.
