摘要： A snap-action drive for a switching device has an energy store, a swinging movable part and a securing device for the movable part. The securing device secures a position of the swinging movable part by a force effect, wherein a reversal of direction of the movable part takes place counter to the force effect.

摘要： An undercarriage for use with a circuit breaker includes a bottom plate, a front beam removably coupled to the bottom plate via a lead screw, wherein the lead screw is configured to engage with a threaded support that is coupled to the bottom plate to facilitate racking the circuit breaker in a switchgear. The undercarriage also includes a keylock assembly configured to enable racking the circuit breaker in the switchgear. The keylock assembly includes a lock and an interlock configured to couple to the lock such that the interlock is movable between a locked position and an unlocked position, wherein engagement of a racking handle with the lead screw is enabled when the interlock is in the unlocked position.

摘要： A ground test switch comprises a terminal plate electrically connected to a movable contact member but electrically insulated from a closed vessel enclosing a high-voltage conductor, a grounding conductor disconnectably electrically connecting the terminal plate to a member maintained at ground potential, and a locking device locking the movable contact member against movement when the grounding conductor is detached from the connecting position. The operator may forget to mount the grounding conductor in the switch again after a ground test. Such a trouble can be readily detected because the movable contact member is locked against movement.
摘要翻译： 地面测试开关包括电连接到可动触点构件但与封闭高压导体的封闭容器电绝缘的端子板，可断开地将端子板电连接到保持接地电位的构件的接地导体，以及锁定装置 当接地导体从连接位置脱离时，锁定可动接触件防止移动。 地面试验后，操作者可能会忘记将接地导体重新安装在开关中。 可以容易地检测到这种麻烦，因为可动接触构件被锁定以防止运动。
