注:断路器脱扣跳闸后,电动操作机构必须先使断路器再扣,然后才能合闸。
Notes: When the breaker is tripped, the motor-operated mechanism must trip the breaker first, and then close.
9.5 手动操作机构
9.5.1 安装前,安装操作手柄的开关柜门按图开好孔,开孔
中心离铰链距离大于 100 mm。
9.5.2 把已在面盖上固定好操作机构的断路器安置于安装板上,并稍作固定。
9.5.3 把操纵杆方轴固定于操作机构上安置方轴的方孔内。
9.5.4 关上开好孔的门板,调整断路器的位置,使方轴中心与手柄开孔中心一致。
9.5.5 打开开关柜门板,当转动手柄"OFF"指示在水平位置时固定好手柄。
9.5.6 合上安装好转动手柄的开关柜门板,试着操作手柄,转动应灵活自如,并且手柄在水平位置时,断
路器应分闸,手柄在垂直位置时,断路器应合闸。
9.5 Manual operating mechanism
9.5.1 Before installation, a switch cabinet door for installing
operating handle is holed in accordance with the diagram.
Distance between the holed part and the hinge is greater than 100 mm.
9.5.2 The breaker with an operating mechanism fixed on cover is installed on the installation
panel and slightly fixed then.
9.5.3 The square shaft of an operating rod is fixed in a square hole on the operating mechanism.
