    • A hybrid switch assembly (50,150,250,350) is provided for a vacuum switch, such as for example a vacuum interrupter (2). The vacuum interrupter (2) includes a vacuum envelope (4), a fixed contact assembly (6) partially within the vacuum envelope (4), and a movable contact assembly (8) partially within the vacuum envelope (4) and movable between a closed position in electrical contact with the fixed contact assembly (6) and an open position spaced apart from the fixed contact assembly (6). The hybrid switch assembly (50) includes at least one radial magnetic field generating mechanism, such as for example a spiral contact (52,53; 152,153; 252,253) or cup member (352,353), and a number of axial magnetic field generating mechanisms each comprising a ferromagnetic or ferrimagnetic member such as for example, a horseshoe plate assembly (54,56; 154,156; 252,254; 352,354). Each axial magnetic field generating mechanism (54,56; 154,156; 252,254; 352,354) is disposed within the vacuum envelope (4) proximate a corresponding radial magnetic field generating mechanism (52;53; 152,153; 252,253; 352,353).

    • A gas-insulated switchgear (91-97) includes a fixed-side electrode (10) and a movable-side electrode (20) facing each other in a container filled with an insulating gas. The fixed-side electrode (10) includes a tubular fixed-side conducting contact (11) and a fixed-side shield (12) for housing the fixed-side conducting contact (11). The movable-side electrode (20) includes a movable conductor (21) driven by a driving unit to be connected to and separated from the fixed-side conducting contact (11). The gas-insulated switchgear (91-97) includes a fixed-side arc shield (13) in the form of a circular plate. The fixed-side arc shield (13) is made of an arc-resistant member and has an opening (13x) of a diameter larger than the outer diameter of the movable conductor (21), the opening (13x) being formed on the side of the fixed-side shield (12) facing the movable-side electrode. The fixed-side arc shield (13) is formed into a thin plate so that the fixed-side arc shield (13) causes an arc current to flow outward in a radial direction during contact parting of the fixed-side conducting contact (11) and the movable conductor (21) to generate magnetic flux on a surface thereof in a circumferential direction that produces a force acted on an arc in the direction of a central axis, thereby restricting the arc in the vicinity of the opening (13x).
    • 气体绝缘开关装置(91-97)包括在填充有绝缘气体的容器中彼此面对的固定侧电极(10)和可动侧电极(20)。 固定侧电极(10)包括用于容纳固定侧导电触头(11)的管状固定侧导电触头(11)和固定侧护罩(12)。 可移动侧电极(20)包括由固定侧导电触头(11)连接并与固定侧导电触头(11)分离的驱动单元驱动的可动导体(21)。 气体绝缘开关装置(91-97)包括圆板形式的固定侧电弧罩(13)。 固定侧电弧罩(13)由耐弧构件制成,具有比可动导体(21)的外径大的直径的开口(13x),开口(13x)形成在侧面 (12)面对可动侧电极。 固定侧电弧屏蔽(13)形成为薄板,使得固定侧电弧屏蔽(13)在固定侧导电触头(11)的接触分离期间使电弧电流沿径向向外流动, 和可动导体(21),在周向上产生磁通量,该磁通在中心轴线方向产生作用在电弧上的力,从而限制开口(13x)附近的电弧。

    • The invention relates to a gas circuit breaker switch (5) which can be integrated inside a switching device insulated in a dielectric gas, said switch (5) comprising an arc chute (1) inside which a fixed contact (3) and a moving contact (4) are arranged. The integration of the contacts (3, 4) inside at least one casing (19, 20) corresponding to the arc chute (1) allows reducing distances between phases, in addition to preventing any incident in one phase from affecting the remaining phases, and finally more compact electrical equipment is obtained. The switch (5) also comprises at least one generation means (6) for generating at least one gas, at least one blowout/intake means (7) for at least one extinguishing gas and at least one generation means (2) for generating a magnetic field, such that the electric arc generated between the contacts (3, 4) of the switch (5) can be extinguished by combining said means (6, 7, 2).
