Contact disk for vacuum switch pipe of high electric field strength, has set of slots to reduce eddy current in contact disk, where slots are arranged completely within contact disk and one of slots is rectilinearly arranged

摘要

The disk (1) has a set of slots (2) to reduce eddy current in the contact disk, where the slots are arranged completely within the contact disk. The thickness of the contact disk in an interior region is smaller than the thickness in an edge area, where one of the slots is rectilinearly arranged. One of the slots is flexed or bent, where one of the slots is arranged in a radial direction in a spiral form. A round portion (3) with radius larger than the thickness of the contact disk in the interior region is arranged at an outer edge of the disk.
