ABSTRACT:
A single barrel puffer circuit interrupter is taught. The single barrel accomplishes the multiple purposes of electrical insulation between terminals, basic support and puffer gas containment. The circuit interrupter has a movable nozzle-piston arrangement fixedly attached to a movable cylindrical hollow arcing contact. The nozzle slidably engages a second cylindrical, hollow arcing contact and is disposed in slidable but sealed relationship therewith at all times, thus providing a shield between the arcing contact and the barrel of the circuit interrupter. In addition, one of the arcing contacts overlaps the other in telescoping relationship when the contacts are closed. This provides a lost motion feature for the puffer. The lost motion feature allows the puffer gas to be compressed for a short period of time by the piston during a contact opening operation in a completely enclosed region before the gas is provided to the region of an electric arc between the opening contacts.
