ABSTRACT:
A puffer circuit interrupter is taught. Arc extinguishing gas is vented through a hollow stationary arc contact into a gas condenser. The gas condenser is an elongated toroid having a well-defined open central region. The gas condensing portion of the toroid is formed from overlapping layers of wound copper mesh. The elongated central opening of the toroid is aligned with the hollow electrode for receiving the arc quenching gas. At one end of the condenser is an external conductor for the puffer circuit interrupter. At the other end of the condenser is a disc having a central opening therein through which the hollow electrode protrudes. The condenser is thus firmly maintained longitudinally between the disc and the external electrode. Surrounding the circumferential periphery of the condenser and bridging the space between the disc and the electrode are longitudinally disposed circumferentially spaced fingers. The spaced fingers form a support cage for the condenser. Furthermore, the fingers extend longitudinally beyond the disc for making electrical contact with a movable contact in the circuit breaker apparatus. These fingers thus act as the rated current carrying conductors when the circuit breaker apparatus is in the closed state.
