摘要

本文将目前应用于三相四线制低压配电网的三相不平衡治理装置归纳为3种类型

即投切电容器型、换相开关型和VSC换流器型。通过对其工作原理、接线方式及适用范围进行详细介绍

使读者对当前不平衡治理装置有深入认识

并能够根据现场实际条件选择正确的补偿装置型式。最后结合四川某偏远山村低压配网负荷三相不平衡引起"低电压"的典型治理案例进一步说明不平衡治理装置正确选型的重要性。

Abstract

In this paper

the three-phase unbalance control device for three-phase four-wire distribution network can be divided into three categories:Switching capacitor type

commutation switch type and VSC type.The reader can have a deep understanding of the present unbalance control device through the detailed introduction of their operating principle

wiring mode and scope of application and can select correct type of compensation device as per the actual condition at site.Finally

the importance on correctly selecting the unbalance control device is illustrated further with the low voltage typical control case due to three-phase unbalance of low voltage distribution network from remote mountain village of Sichuan Province.
