    • An improved vacuum interrupter (1000) is disclosed. The vacuum interrupter (1000) includes end covers (1005) having a curved or looped portion (1022), which serves to connect a coil segment (1015) of the vacuum interrupter (1000) to a ceramic envelope (1010) of the vacuum interrupter (1000), and thereby help maintain a vacuum seal for the interrupter. The curved portion (1022) acts as a spring when the vacuum interrupter (1000) is exposed to heat, thereby absorbing any expansion or contraction in the length of the vacuum interrupter due to the heating or cooling. The curved portion (1022) also protects an end of the ceramic envelope (1010) from any build-up of metallic arcing products and eliminates the need for elaborate fixturing during assembly. Additionally, a guide (1045) may be affixed to the end cover (1005), the guide (1045) having ears (1302) which ride in a slot (1050) in a moving rod (1035) of the vacuum interrupter (1000), to thereby prevent a twisting of a bellows (1030) of the interrupter during a brazing process. Thus, no elaborate fixturing is necessary to prevent this twisting.
    • 公开了一种改进的真空断路器(1000)。 真空断路器(1000)包括具有弯曲或环形部分(1022)的端盖(1005),其用于将真空断路器(1000)的线圈段(1015)连接到真空断路器的陶瓷外壳(1010) (1000),从而有助于维持断路器的真空密封。 当真空断路器(1000)暴露于热量时,弯曲部分(1022)用作弹簧,从而由于加热或冷却而吸收真空断路器长度的任何膨胀或收缩。 弯曲部分(1022)还保护陶瓷封套(1010)的端部免受金属电弧产物的任何积聚,并且在组装期间不需要精心的固定。 另外,引导件(1045)可以固定到端盖(1005)上,具有耳环(1302)的引导件(1045)可以悬挂在真空断路器(1000)的移动杆(1035)中的槽(1050)中, ,从而防止在钎焊过程中断路器的波纹管(1030)的扭转。 因此,不需要精心的夹具来防止这种扭曲。

    • To enable gas discharge at a low pressure, at least two main electrodes separated by a distance d are provided, defining in a circuit-breaking case the cathode and the anode with the spacing required for said gas discharge at a low pressure. The gas discharge is triggered by increasing the electron density in the hollow cathode space. It is also necessary for the cathode to have at least one opening and preferably that both the cathode and the anode have aligned openings facing each other. According to the invention, elements are mounted on the main electrodes to create a magnetic field above the discharge between said main electrodes (1, 1a, 2, 2a). These elements are used to generate a magnetic field oriented either substantially parallel to the current flow during the discharge or transversal to the latter. Said elements are advantageously realized in the form of stretch punctures (11, 11', 21, 21') either in hollow cylinders forming part of the anode (1) and the cathode (2) designed as hollow electrodes or in the supply conductors associated therewith.
