Vacuum capacitor
First Claim
1. A vacuum capacitor comprising:
- an insulating envelope;
a pair of end electrodes, each end electrode being brazed to a corresponding end of the insulating envelope and being formed together with the insulating envelope to constitute a vacuum vessel;
a plurality of cylindrical electrode plates, each cylindrical electrode plate, constituting one of a pair of cylindrical electrodes, having a mutually different diameter and being extended along the insulating envelope from an inner surface of the corresponding one of the pair of end electrodes so as to be inserted into a space between the mutually adjacent cylindrical electrode plates constituting the other of the pair of cylindrical electrodes; and
a positioning member to position one of the pair of cylindrical electrodes to the other of the pair of cylindrical electrodes in such a manner as to equalize a spatial interval between each cylindrical electrode plate and wherein each of the pair of end electrodes is formed substantially in a letter T shape of cross section and wherein the positioning member comprises a plurality of circular U-shaped rails extended concentrically at equal spatial intervals and vertically on the inner surface of each of the pair of end electrodes, each circular U-shaped rail receiving the corresponding one of the cylindrical electrode plates of each of the pair of cylindrical electrodes.

Abstract
A vacuum capacitor and its manufacturing method are disclosed. The vacuum capacitor comprises: an insulating envelope; a pair of end electrodes, each end electrode being brazed under a non-oxidation atmosphere to a corresponding end of the insulating envelope and being formed together with the insulating envelope to constitute a vacuum vessel; a plurality of cylindrical electrode plates constituting a pair of cylindrical electrodes, each cylindrical electrode plate constituting one of the pair of cylindrical electrodes having a mutually different diameter and being extended along the insulating envelope from an inner surface of the corresponding one of the pair of end electrodes so as to be inserted into a space between the mutually adjacent cylindrical electrode plates constituting the other of the pair of cylindrical electrodes; and a positioning member to position one of the pair of cylindrical electrodes to the other of the pair of cylindrical electrodes in such a manner as to equalize a spatial interval between each cylindrical electrode plate constituting the one of the pair of cylindrical electrodes and that constituting the other of the pair of cylindrical electrodes.
