Abstract
This vacuum interrupter is for high voltage applications and comprises a tubular metal central shield around its arcing gap for condensing arc-generated vapors and two tubular metal end shields located at opposite ends of the interrupter. Two tubular metal intermediate shields are respectively provided at opposite ends of the central shield between the central shield and the adjacent end shields. These intermediate shields are normally electrically isolated from the central shield and the end shields. Each intermediate shield is disposed adjacent to the central shield but does not axially overlap with the central shield. Each intermediate shield also surrounds the inner end of its associated end shield in radially-spaced, axially-overlapping relationship with the associated end shield.
