    Abstract: A high-voltage fuse includes a self-supporting fuse ribbon fuse link, or fusible element, i.e., one that is not provided with, or wound around, a link supporting insulating mandrel. The fusible element is formed of resilient material, preferably relatively hard silver, and forms a loaded extension spring. The fusible element is bent at a plurality of points in zigzag fashion having planar sections between bends. These planar sections enclose acute angles close to 90*. The ribbon fuse link has a plurality of serially arranged perforations and each of the aforementioned planar sections encompasses a plurality of such perforations. Each of the plurality of points where the fuse link, or fusible element, is bent is coextensive with one of said plurality of perforations thereof.

    Abstract translation: 高压保险丝包括自支撑保险丝熔丝连接件或可熔元件，即，不支撑绝缘心轴的连杆支撑件，或不缠绕的部件。 易熔元件由弹性材料形成，优选地是较硬的银，并形成一个加载的拉伸弹簧。 可熔元件在曲折形式的多个点处弯曲，在弯曲之间具有平面部分。 这些平面部分包围接近90°的锐角。 带状熔丝连接件具有多个串联布置的穿孔，并且每个上述平面部分包围多个这样的穿孔。 熔断体或易熔元件弯曲的多个点中的每一个与所述多个穿孔中的一个共同延伸。

    Abstract: A current-limiting fuse having a composite fusible element structure which includes a wire section for interrupting overload currents, and a ribbon section having series necks for interrupting major fault currents, or short circuit currents. The wire section is straight and is connected in series with the ribbon section and the ribbon section is formed by a strip of zig-zag-shaped relatively hard and resilient silver forming a self-supporting extension spring tending to maintain the wire section under axial stress.
