    摘要： A switching device for an encapsulated electric power distribution switchgear and an electric power distribution switchgear with at least one such switching device are disclosed. The switching device has a first electrically conducting housing which encloses an actuator mechanism for a first contact assembly and a second electrically conducting housing which encloses a second contact assembly. The first electrically conducting housing is arranged at a distance from the second electrically conducting housing. The switching device further has a third housing which is electrically insulating and arranged between the first electrically conducting housing and the second electrically conducting housing. The switching device is a puffer type switch.

    摘要： A power distribution switchgear including a housing to which a switch is mounted, housing has an opening, the first and second electric contact connected to a first and second conductors. A rotating operating shaft of inserted into the opening, and an actuator having a first end coupled to the shaft and a second end coupled to the second contact. The actuator and shaft made of an electrically insulating material. The shaft supported in the housing by the actuator member. The interface is located at a distance D from the longitudinal axis Y of the shaft that is longer than a distance d between axis Y and a circumferential edge that delimits the opening.

    摘要： A gas-insulated low- or medium-voltage load break switch includes: a housing defining a housing volume for holding an insulation gas at an ambient pressure; a first arcing contact and a second arcing contact arranged within the housing volume, the first and second arcing contacts being movable in relation to each other along an axis of the load break switch and defining a quenching region in which an arc is formed during a current breaking operation; a pressurizing system having a pressurizing chamber arranged within the housing volume for pressurizing a quenching gas from an ambient pressure p0 to a quenching pressure pquench during the current breaking operation; and a nozzle system arranged within the housing volume for blowing the pressurized quenching gas in a subsonic flow pattern from the pressurization chamber onto the arc formed in the quenching region during the current breaking operation. The nozzle system includes at least one nozzle arranged for blowing the quenching gas from an off-axis position predominantly radially inwardly onto the quenching region.
