摘要：
A vacuum circuit breaker comprises a vacuum interrupter operable between a closed state and an open state, and an actuator. The actuator comprises a piezoelectric driving element that is expandable and contractable along an expansion axis in response to an electrical input signal. The actuator further comprises a mechanical amplifying structure extendable along an actuation axis and being mechanically coupled to the piezoelectric driver such that expansion or contraction of said piezoelectric driving element causes the amplifying structure to extend or retract along the actuation axis. The mechanical amplifying structure is coupled to the vacuum interrupter for operating the vacuum interrupter between said closed and open states.
摘要（中）：
真空断路器包括可在闭合状态和打开状态之间操作的真空断续器，以及致动器。 致动器包括压电驱动元件，该压电驱动元件响应于电输入信号沿着扩展轴线可扩展和收缩。 该致动器还包括机械放大结构，该机械放大结构可沿着致动轴线延伸并机械地耦合到压电驱动器，使得所述压电驱动元件的膨胀或收缩使得放大结构沿着致动轴线延伸或缩回。 机械放大结构连接到真空断续器，用于在所述闭合状态和打开状态之间操作真空断续器。
