Summary:PROBLEM TO BE SOLVED: To provide a contact assembly for use in a vacuum interrupter, which overcomes conventional defects relating to a vacuum arc in a contact.SOLUTION: The contact assembly for use in the vacuum interrupter includes a contact disc of a first electrically conductive material, a coil and a contact support. The coil is made from a second electrically conductive material and includes multiple helical sections that are oriented axially with respect to a common central axis. Each of the helical sections includes a proximal end and a distal end such that each of the helical sections is connected at the proximal end to a base made from the second electrically conductive material and is connected at the distal end to the contact disc. The contact support is centered axially within the coil and extends from the base to the contact disc.SELECTED DRAWING: Figure 3 【課題】本発明の一目的は、従来の接点における蒸気アークに関する欠点を克服する、真空インタラプタにおいて使用する接点組立体を提供することである。【解決手段】真空インタラプタにおいて使用する接点組立体は、第１の導電材料の接点円板と、コイルと、接点支持体とを備える。コイルは、第２の導電材料から作製され、共通の中心軸に関して軸方向に向く複数の螺旋セクションを有する。螺旋セクションのそれぞれは、近位端部及び遠位端部を有し、螺旋セクションのそれぞれは、近位端部において第２の導電材料によって作製されたベースに結合され、遠位端部において接点円板に結合されるようになっている。接点支持体は、コイル内で軸方向にセンタリングされ、ベースから接点円板まで延びる。【選択図】図３
