    • The invention provides a column comprising a hinge assembly, the hinge assembly comprising an upper portion (2) pivotally attached to a lower portion (1) for movement about a first pivot axis (5), the upper portion of the hinge assembly being associated with an upper part (12) of the column and the lower portion of the hinge assembly being associated with a lower part (11) of the column, wherein in use, movement of the upper and lower hinge assembly portions about the first pivot axis from a normal position, in which the upper part of the column is relatively upright, causes the upper part of the column to rotate towards the lower part of the column, thereby allowing the upper part the column to be moved to a maintenance position, a connecting means links (3), via second (6) and third (7) pivot axes, the upper and lower portions of the hinge assembly, and the connecting means is associated with a bias means (9) that exerts a force via the connecting means, which urges the upper and lower hinge assembly portions towards the normal position.
    • 本发明提供了一种包括铰链组件的柱,铰链组件包括枢转地附接到下部(1)的上部(2),用于围绕第一枢转轴线(5)运动,铰链组件的上部与 柱的上部(12)和铰链组件的下部与柱的下部(11)相关联,其中在使用中,上部和下部铰链组件部分围绕第一枢转轴线从一个 正常位置,其中柱的上部相对直立,使柱的上部朝向柱的下部旋转,从而允许柱的上部移动到维护位置,连接装置 连杆(3),第二(6)和第三(7)枢转轴线,铰链组件的上部和下部,并且连接装置与通过连接装置施加力的偏压装置(9)相关联, 敦促 上和下铰链组件部分朝向正常位置。

    • A method for recording and having analyzed waveform data associated with an electronic circuit breaker having an electronic trip unit is disclosed. The electronic trip unit has a communication port and is capable of providing to the communication port a first signal representative of a phase current passing through the circuit breaker, and a second signal representative of a conditional event at the circuit breaker. The method includes facilitating the connection of a waveform recorder device to the communication port of the electronic trip unit; facilitating recording in a first memory of the waveform recorder device in a circular queue fashion information relating to the first signal received from the electronic trip unit; and, in response to the second signal received from the electronic trip unit, facilitating the stopping of the recording in the first memory.
    • 公开了一种用于记录和分析与具有电子跳闸单元的电子断路器相关联的波形数据的方法。 电子跳闸单元具有通信端口,并且能够向通信端口提供表示通过断路器的相电流的第一信号,以及表示断路器处的条件事件的第二信号。 该方法包括促进波形记录器装置与电子跳闸单元的通信端口的连接; 便于以与从电子跳闸单元接收到的第一信号有关的循环队列方式记录在波形记录装置的第一存储器中; 并且响应于从电子跳闸单元接收的第二信号,便于在第一存储器中停止记录。
