45,674 PUFFER-TYPE GAS-BLAST CIRCUIT- INTERRUPTER HAVING VARIABLE-AREA STATIONARY COMPOSITE PISTON STRUCTURE ABSTRACT OF THE DISCLOSURE A puffer-type gas-blast circuit-interrupter is provided having an operating cylinder movable over a fixed composite piston structure, the fixed composite piston structure providing a variable cross-sectional area by means of a secondary piston area, preferably annular in configuration, which is releasably latched in a fixed forward position, and, subsequently, during the opening operation of the breaker, collapsed to a retracted position. The composite piston arrangement may be such that upon collapse of the secondary "fixed" piston, the diameter of the surrounding movable operating cylinder may be such as to closely surround the central area of the primary fixed piston structure to retain high-pressure gas within the piston-compression chamber without loss. There results, by the utilization of the variable- area fixed composite piston structure, an improved inter- rupting performance of the circuit-interrupter by giving very high gas pressures early in the opening stroke of the circuit-interrupter, as compared to prior-art conventional structures, which proved such high gas pressure only at a later time in the opening stroke by conventional piston means.
