Abstract (en)
[origin: WO2013045235A1] The invention relates to an arrangement comprising a circuit breaker unit having a first and a second arcing contact piece (4, 5). A contact gap (6) is arranged between the arcing contact pieces (4, 5). A switch gas channel of the circuit breaker unit joins the contact gap to the surrounding area of the circuit breaker unit for removing a switch gas from said contact gap (6). Several barriers (21a, 21b, 21c, 21d, 21e) increasing a flow resistance are arranged successively, at a distance in relation to each other, in the switch gas channel. At least one of the barriers (21a, 21b, 21c, 21d, 21e) is arranged between a first pipe section (12) surrounded by a second pipe section (14), and the second pipe section (14).
