电力系统常用名词术语1.一次回路/主回路与一次设备/主设备:是指电力输送和分配的回路,其主要任务是进行电能的输送和分配。
与其相连的设备称为一次设备或主设备,例如:变压器、断路器、熔断器、接地刀开关、输变配线缆等;通常将终端的用电设备,如:电动机(马达),照明灯等也归在一次设备的范围。
也可以把一次回路理解为由输变配线缆+主设备(变压器、断路器等)+用电设备(马达、照明灯等)构成。
2.二次回路/控制回路与二次设备/控制设备:指对一次设备进行控制、指示、测量(计量)、监视和保护的回路,其主要任务是对一次回路的运行状态、运行参数等进行监控,保证回路的正常运行。
与其相连的设备称为二次设备或控制设备,也叫控制电器,包括:PT(电压互感器)、CT(电流互感器)、接触器、继电器、综合保护装置、断路器辅助接点、各种操作按钮、计量仪表、二次回路的控制线缆等。
3.开关柜:是指按一定的线路方案将一次设备、二次设备组装而成的成套配电装置,是用来对线路、设备实施控制、保护的,分固定式和手车式,而按进出线电压等级又可以分高压开关柜(固定式和手车式)和低压开关柜(固定式和抽屉式)。
开关柜的结构大体类似,主要分为母线室、断路器室、二次控制室(仪表室)、馈线室,各室之间一般有钢板隔离。
内部元器件包括:母线(汇流排)、断路器、常规继电器、综合继电保护装置、计量仪表、隔离刀、指示灯、接地刀等。
从应用角度划分:进线柜:又叫受电柜,是用来从电网上接受电能的设备(从进线到母线),一般安装有断路器、CT、PT、隔离刀等元器件。
出线柜:也叫馈电柜或配电柜,是用来分配电能的设备(从母线到各个出线),一般也安装有断路器、CT、PT、隔离刀等元器件。
母线联络柜:也叫母线分断柜,是用来连接两段母线的设备(从母线到母线),在单母线分段、双母线系统中常常要用到母线联络,以满足用户选择不同运行方式的要求或保证故障情况下有选择的切除负荷。
PT柜:电压互感器柜,一般是直接装设到母线上,以检测母线电压和实现保护功能。
