3.2

快速换相型三相不平衡治理装置three-phaseunbalancemitigationdeviceswithrapidphase-

switching

由一个控制单元和若干个换相单元组成，通过控制单元控制换相单元自动快速调节单相用电负荷

相别，使相应低压线路的用电负荷在三相上基本平衡分布的装置。

注：以下简称装置。

3.3

控制单元controlunit

1

T/CPSS1001—2024

具备设备运行状态监测、发出换相指令等功能的设备，是装置的组成部分之一。可以独立存在，也

可以集成在其他智能终端设备中。

3.4

换相单元phase-switchingunit

由晶闸管、继电器等电力电子器件的组合构成，具备信息采集、接收控制单元发出的指令、将单相

负荷在三相之间切换等功能的设备，是装置的组成部分之一。

3.5

换相切换时间phase-switchinginterval

换相单元将单相负荷从原工作相断开到现工作相接通的时间。

4一般要求

4.1装置组成

装置组成如图1所示。控制单元应安装在配电变压器出线端，换相单元应安装在低压供电回路单相

负荷、或单相分支线前端。换相单元的内部结构见附录A。

图1装置组成示意图

4.2电气接线

换相单元应采用三相输入、单相输出接线方式。

5使用条件

5.1正常使用条件

5.1.1温度条件

周围空气温度不超过40℃，且在24h内的平均温度不超过35℃。

周围空气温度的下限为-25℃。

5.1.2湿度条件

最高温度25℃时，相对湿度短时可达100%。
