用于断路器主动断开止动特征的设备和方法
摘要：
一种具有主动断开止动特征的断路器包括：操作杆，所述操作杆可旋转地联接至侧架；拉杆，所述拉杆联接至所述侧架；以及上肘节连杆和止动连杆，所述上肘节连杆和所述止动连杆分别可旋转地联接至所述拉杆。所述上肘节连杆可以构造为使所述止动连杆旋转。所述操作杆可以构造为：在所述断路器的所述主触头未焊接或者在其它方面粘接在一起的情况下可旋转地在接通位置和断开位置来回移动。如果所述主触头焊接或者在其它方面粘接在一起，则所述上肘节连杆可以构造为使所述止动连杆旋转至这样的位置，其中，所述止动连杆可以构造为防止所述操作杆移动到所述断开位置中。作为其它方面，同样提供了组装断路器主动断开止动特征的方法。
摘要（英）：

A circuit breaker having a positive-off stop feature includes an operating lever rotatably coupled to a side frame, a tension lever coupled to the side frame, and an upper toggle linkage and a stop link each rotatably coupled to the tension lever. The upper toggle linkage may be configured to rotate the stop link. The operating lever may be configured to move rotatably to and from an ON position and an OFF position provided the main contacts of the circuit breaker are not welded or otherwise stuck together. Should the main contacts become welded or otherwise stuck together, the upper toggle linkage may be configured to rotate the stop link to a position wherein the stop link may be configured to prevent the operating lever from moving into the OFF position. Methods of assembling a circuit breaker positive-off stop feature are also provided, as are other aspects.
