Abstract (en)
[origin: WO2007016797A1] The invention relates to a self-blast circuit breaker wherein the inner contact (3) is provided with a control body (9), running into or against the outer contact (2). The control body (9) forces the arc into an arc zone (10) in the form of a hollow cylinder. A more rapid build-up of pressure is thus achieved with an improved charging of the quenching chamber (5) of the breaker with quenching gas. By means of suitable shaping of the control body (9) the gas flow out of or into the arc zone (10) can be optimised.
