ABSTRACT:
A dry capacitor interrupter employs a sealed container spaced about a dry capacitor to contain gas emitted upon failure of the dry capacitor and to thereby permit gas pressure to develop within the container regardless of the location on the dry capacitor from which the gas is emitted. A deformable cover on the container is deformed outward by the gas pressure to thereby break a connection between a terminal stud and a tab within the container. The breakage of the connection effectively removes the dry capacitor from electrical connection to external circuits.
