  • High-voltage power switch with a field electrode
    Patent number: 5728988
    Abstract: High-voltage power switch including a first and a second contact piece that form an air gap in the switched-off state, a compression piston that surrounds the first contact piece, a drivable compression cylinder that surrounds the second contact piece in the switched-on state, and a first field electrode that surrounds the second contact piece in the switched-off state and is axially movable in relation thereto. The high-voltage power switch also provides that the first field electrode is insulated from the compression cylinder and axially movable in relation thereto and the compression cylinder is displaced by a distance from the second contact piece in the switched-off state.
