    • A gas-insulated switchgear includes a fixed-side electrode having a tubular fixed-side-conducting contact and a fixed-side shield for housing the fixed-side-conducting contact, and a movable-side electrode having a movable conductor driven by a driving unit to be connected to and separated from the fixed-side-conducting contact, facing each other in a container filled with an insulating gas. The switchgear includes a fixed-side-arc shield in the form of a circular plate, which is made of an arc-resistant member and has an opening of a diameter larger than the outer diameter of the movable conductor, the opening being formed on the side of the fixed-side shield facing the movable-side electrode. The fixed-side-arc shield is formed into a thin plate so as to cause an arc current to flow outward in a radial direction during contact parting of the fixed-side-conducting contact and the movable conductor to generate magnetic flux on a surface thereof in a circumferential direction.
    • 一种气体绝缘开关装置,包括具有管状固定侧导电触点的固定侧电极和用于容纳固定侧导电触点的固定侧屏蔽,以及具有由驱动驱动的可动导体的可动侧电极 单元,其被连接到固定侧导电接触件并与固定侧导电接触件分离,在填充有绝缘气体的容器中彼此面对。 开关装置包括圆弧形的固定侧弧形罩,其由抗弧构件制成,具有比可动导体的外径大的直径的开口,该开口形成在 侧固定侧面对着可动侧电极。 固定侧电弧屏蔽形成为薄板,以便在固定侧导电触点和可动导体的接触分离期间使电弧电流沿径向向外流动,以在其表面上产生磁通量 在圆周方向。
