摘要： The present invention provides a spring offset device structured to extend between a circuit breaker frame and a trip mechanism. The offset device includes an offset member disposed on a trip device banana link, a spring anchor disposed on the frame assembly, and a spring extending between the offset member and the spring anchor. The spring anchor is spaced from the hatchet pin assembly and, preferably positioned so that the longitudinal axis of the spring remains on a single side of a hatchet pin assembly axis as the banana link moves between a closed position, an open position, and a reset position. The offset member and the spring anchor are structured so that, when the hatchet plate is in the closed position, the spring creates an opening force on the hatchet plate biasing the hatchet plate toward the open position, and when the hatchet plate is in the reset position, the spring creates a closing force on the hatchet plate biasing the hatchet plate toward the closed position.
摘要翻译：本发明提供一种构造成在断路器框架和跳闸机构之间延伸的弹簧偏移装置。偏移装置包括设置在跳闸装置香蕉连杆上的偏移构件，设置在框架组件上的弹簧锚杆以及在偏置构件和弹簧锚固件之间延伸的弹簧。弹簧锚杆与斧形销组件间隔开，优选地定位成使得当香蕉连杆在关闭位置，打开位置和复位之间移动时，弹簧的纵向轴线保持在斧形销组件轴线的单侧上位置。偏移构件和弹簧锚构造成使得当斧形板处于关闭位置时，弹簧在煞车板上产生朝向打开位置偏置斧形板的打开力，并且当斧形板处于复位状态时位置上，弹簧在斧形板上产生一个关闭力，从而将斧形板偏向关闭位置。
