Abstract: PROBLEM TO BE SOLVED: To provide a power circuit breaker with high power breaking capacity, efficiently exhausting arc gas with high temperature from an arc chamber.
SOLUTION: The power circuit breaker comprises an arc extinction chamber having an arc chamber formed into nearly a radial symmetric shape, extending along a longitudinal axis line 1 filled with insulation gas. The extinction chamber has at least two contact members, out of which at least one contact member is formed into a pipe-shaped hollow contactor 2. the pipe-shaped hollow space is formed in order to release the gas with high temperature from the arc chamber to an exhaustion tab 10. In order to make the gas with high temperature radially deflect into the exhaustion tab 10, a deflection part 4 interlocking with at least one of first opening parts 6 is arranged at the side surface of the hollow contactor 2 facing the opposite side of the arc chamber. The exhaustion tab is communicated with an extinction chamber tab 14 through at least one of the second opening parts 13. Further, at least one intermediate tab 7 is formed between the hollow contactor 2 and the exhaustion tab 10.

Abstract: The breaker has an arcing chamber filled with an isolating gas, extends along a longitudinal axis. A deflection device (4) interacts with an opening in a hollow contact (2). The device is arranged on a side of the contact facing away from an arc area, for radial deflection of hot gases into an exhaust volume. An intermediate volume (7) is provided between the hollow contact and an exhaust body (10).
