断路器
摘要：
提供了一种包括单极断开单元和打开/闭合机构单元的断路器，所述单极断开单元具有通过电弧气体使脱扣杆旋转的压力脱扣装置，所述打开/闭合机构单元随着所述脱扣杆通过所述压力脱扣装置旋转而被调节为处于脱扣状态。该压力脱扣装置包括：第一壳体，其连接到单极断开单元，并且具有电弧气体排放孔；屏障，其定位在电弧气体排放孔的前方，并且通过经由电弧气体排放孔排放的电弧气体而弯曲；弹射器，其位于第一壳体上，并且构造为在通过经由电弧气体排放孔排放的电弧气体移动的同时驱动脱扣杆；以及第二壳体，其连接为覆盖第一壳体。
摘要（英）：

Provided is a circuit breaker including a single pole breaking unit with a pressure trip device that rotates a trip bar through an arc gas and an opening/closing mechanism unit adjusted to be in a trip state as the trip bar rotates through the pressure trip device. The pressure trip device includes: a first case connected to the single pole breaking unit and having an arc gas discharge hole; a barrier positioned in the front of the arc gas discharge hole and bent through an arc gas discharged through the arc gas discharge hole; a shooter seated on the first case and configured to drive the trip bar while moving through the arc gas discharged through the arc gas discharge hole; and a second case connected to cover the first case.
