    • A compact and economical gas-insulated switchgear is provided. The gas-insulated switchgear includes: a grounding metal housing 1 filled with insulating gas, and in which the disconnector part 2 having a moving side electrode part 2a and a stationary side electrode part 2b is accommodated; and composite insulating shields 17a, 17b integrally formed into one metal-dielectric member in which surface of a high electric field part located in the vicinity of ends of openings is coated with a dielectric so as to cover the moving side and stationary side electrode parts 2a and 2b with the dielectric. To form the composite insulating shields 17a, 17b, a metal shield of less than 0.6 in non-uniform constant before coating with the dielectric is coated with dielectrics 18a, 18b having a thickness of not more than approximately 30% of an inter-electrode distance from a facing electric-field relaxation shield.
    • 提供紧凑经济的气体绝缘开关柜。 气体绝缘开关装置包括:填充有绝缘气体的接地金属壳体1,其中容纳有移动侧电极部分2a和固定侧电极部分2b的断路器部分2; 以及整体形成为一个金属电介质构件的复合绝缘屏蔽17a,17b,其中位于开口端部附近的高电场部分的表面涂覆有电介质以覆盖移动侧和固定侧电极部分2a 和2b与电介质。 为了形成复合绝缘屏蔽17a,17b,在用电介质涂覆之前,以不均匀的常数小于0.6的金属屏蔽层涂覆有不大于电极间距离的大约30%的电介质18a,18b 从一个面对的电场放松盾牌。

    • According to one embodiment, an image generation unit generates a first image during a large aperture period and a second image during a small aperture period. An image combining unit generates a composite image based on the latest second image and the specific first image. A display unit displays the composite image in real time. A determination unit determines whether to update the first image based on an index associated with the anatomical positional shift between the first image and the second image. A driving control unit enlarges a aperture to the large aperture, when the determination unit determines to update, and maintains the aperture at the small aperture, when the determination unit determines not to update.
    • 根据一个实施例,图像生成单元在小光圈周期期间在大光圈周期和第二图像期间产生第一图像。 图像合成单元基于最新的第二图像和特定的第一图像生成合成图像。 显示单元实时显示合成图像。 确定单元基于与第一图像和第二图像之间的解剖位置偏移相关联的索引来确定是否更新第一图像。 当确定单元确定不更新时,当确定单元确定更新并维持小孔径处的孔时,驱动控制单元将孔径扩大到大孔径。
