断路器灭弧单元

Circuit breaker unit

Abstract

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).
本发明涉及一种具有断路器灭弧单元的装置,所述断路器灭弧单元具有第一与第二电弧触头(4、5)。在电弧触头(4、5)之间设触头间隔(6)。为了从所述触头间隔(6)引出开关气体,断路器灭弧单元的开关气体通道连通触头间隔与断路器灭弧单元的周围环境。在所述开关气体通道的路径内设置多个增大流动阻力的屏障(21a、21b、21c、21d、21e),它们彼此相继地互相间隔地排布。在被第二管段(14)围绕的第一管段(12)与第二管段(14)之间,设置至少一个这种屏障(21a、21b、21c、21d、21e)。
