    • Apparatus is provided for an electrical circuit breaker for preventing the handle thereof from being moved to the OFF position when the electrical contacts of the circuit breaker are welded closed. This apparatus mechanically limits the travel of the operating handle so that it may not be moved to the OFF position when the electrical contacts are closed. This restrictor apparatus as it is called is mechanically connected to, but out of direct contact with the handle arm of the circuit breaker. The mechanical linkage between the operating handle and the contact arm of the circuit breaker includes a projection. During the foregoing condition, the projection will interact with a crossbar assembly for the contact arm of the circuit breaker. If an attempt is made to move the handle to the OFF position while the contacts remain welded closed, the crossbar assembly is oriented with respect to the path of travel of the projection to prevent the projection from movement past the crossbar assembly and thus to prevent movement of the handle to the OFF position. If, however, the contacts are open as an attempt is made to move the handle to the OFF position, the crossbar assembly will become disposed differently relative to the path of travel of the projection such that the projection will freely move past the crossbar assembly thus allowing the handle mechanism to be moved completely to the OFF position.
    • 当断路器的电触点被焊接封闭时，设置用于防止其手柄移动到断开位置的电路​​断路器的装置。 该装置机械地限制操作手柄的移动，使得当电触头闭合时，该手柄可能不会移动到OFF位置。 这种限制装置被称为机械地连接到断路器的手柄臂，而不是与断路器的手柄臂直接接触。 断路器的操作手柄和接触臂之间的机械联动装置包括一个突起。 在上述情况下，突起将与用于断路器的接触臂的横杆组件相互作用。 如果在触点保持焊接闭合的同时尝试将把手移动到OFF位置，则横杆组件相对于突起的行进路径定向，以防止突出部移动通过横梁组件，并且因此防止移动 把手处于OFF位置。 然而，如果尝试将触点移动到OFF位置，则横杆组件将相对于突起的行进路径不同地设置，使得突出部自由移动通过横梁组件，因此 允许把手机构完全移动到OFF位置。

    • A close latch interlock assembly is provided for an electrical switching apparatus, such as a circuit breaker, which includes a stored energy mechanism, such as a closing spring. The close latch interlock assembly includes a close D-shaft pivotable between a latched and unlatched positions corresponding to the closing spring being chargeable and discharged, respectively. An actuator is movable between an unactuated position corresponding to the close D-shaft being disposed in the latched position, and an actuated position corresponding to the close D-shaft being movable toward the unlatched position. A release member cooperates with the actuator and is pivotably coupled to the first end of a transfer link. The second end of the transfer link extends toward the close D-shaft. When the actuator is moved toward the actuated position, it moves the release member, thereby moving the transfer link and pivoting the close D-shaft toward the unlatched position.
    • 提供了一种用于诸如断路器的电气开关装置的闭锁联锁组件，其包括诸如闭合弹簧的存储能量机构。 闭锁闩锁联锁组件包括可分别在对应于关闭弹簧的闩锁和解锁位置之间枢转的紧密D-轴。 致动器可以在与紧密D-轴相对应的未致动位置在闩锁位置之间移动，并且致动位置对应于紧密D-轴能够朝向解锁位置移动。 释放构件与致动器协作并且可枢转地联接到传送连杆的第一端。 传送连杆的第二端朝着近距离D轴延伸。 当致动器朝向致动位置移动时，其移动释放构件，从而移动传送连杆并将闭合D轴朝向解锁位置枢转。
