    • The electric control to reset a circuit breaker is formed by a sub-assembly (10) to be coupled to the mechanism (60) of the circuit breaker. At the end of the charging travel of the closing spring a control cam (46) disconnects and stops the motor. The charging position is defined by a latch interlocking the charging cam (62), a closing operation being induced by the release of the latch and a limited rotation of this charging cam (62). The link shaft between the motor reducing sub-assembly or block (10) and the mechanism (60) transmits this closing limited rotation to the control cam (46), which induces the restarting and the connecting of the motor for a reset operation of the closing spring.
    • 用于复位断路器的电气控制器由子组件(10)形成,以便联接到断路器的机构(60)。 在闭合弹簧的充电行程结束时,控制凸轮(46)断开并停止电动机。 充电位置由与充电凸轮(62)互锁的闩锁限定,由释放闩锁引起的关闭操作和该充电凸轮(62)的有限旋转。 电动机减速子组件或块(10)和机构(60)之间的连杆轴将该关闭限制旋转传递到控制凸轮(46),这引起电动机的重新起动和连接,用于复位操作 关闭春天。

    • An electromagnetic actuator comprises a fixed magnetic circuit made of ferromagnetic material and a movable assembly designed to slide axially between a rest position and an active position. Two return springs bias the movable assembly to its rest position, the second spring having a greater stiffness than the first one. An excitation circuit generates a magnetic flux which is designed, in inrush mode, to move the movable assembly from its rest position to its active position and, in holding mode, is sufficient to hold the movable assembly in the active position. In a first part of the axial travel of the movable assembly from its rest position to its active position, the action of the first spring is preponderant, whereas in the remaining travel up to the active position, the action of the second spring is preponderant.
    • 电磁致动器包括由铁磁材料制成的固定磁路和设计成在静止位置和活动位置之间轴向滑动的可移动组件。 两个复位弹簧将可移动组件偏压到其静止位置,第二弹簧具有比第一弹簧更大的刚度。 励磁电路产生以涌流模式设计的磁通量,以将可移动组件从其静止位置移动到其活动位置,并且在保持模式下足以将可移动组件保持在活动位置。 在可移动组件从其静止位置到其主动位置的轴向运动的第一部分中,第一弹簧的作用是主要的,而在剩余行程中,直到活动位置,第二弹簧的作用是主要的。
