Abstract
A brazing structure for a vacuum container is provided. The vacuum container includes: a fixed conductor on which a fixed electrode is supported; a movable conductor on which a movable electrode is supported; a flange pipe which is bonded to the movable conductor coaxially with the fixed electrode and the movable electrode; and a ceramic pipe which is provided coaxially therewith. One end of the ceramic pipe is bonded to the fixed conductor by brazing, with a linking flange pipe therebetween, and the other end thereof is bonded to the flange pipe by brazing, with a linking flange pipe therebetween. The linking flange pipe includes a bonding portion that is bonded to the ceramic pipe by active metal brazing using an AgCuTi-based, AgCuInTi-based, or AgCuSnTi-based metal.
Claims4
A vacuum capacitor having a brazing structure for a vacuum container containing a pair of electrodes, the vacuum capacitor comprising:
- the vacuum container including:
- a first conductor supporting a first one of the pair of electrodes;
- a second conductor supporting a second one of the pair of electrodes;
- a flange pipe joined to the second conductor coaxially with the pair of electrodes;
- a ceramic pipe disposed coaxially with the pair of electrodes, the ceramic pipe comprising a first end and a second end, the first end and the second being unmetallized;
- and
- a connection flange pipe connecting the ceramic pipe to the first conductor or the flange pipe,
- wherein the connection flange pipe includes:
- a junction joined to the unmetallized first end and the unmetallized second end of the ceramic pipe by active metal brazing with use of an AgCuTi-based, AgCuInTi-based, or AgCuSnTi-based metal;
- and
- a field-relaxing ring disposed on an outer side or an inner side of the junction.
