摘　　要：对馈线众多的低压配电线路,目前主要有以下方法来实现系统监测:(1)采用电流互感器接多功能电力监控仪,加485通讯表实现多路系统监测;(2)采用电流互感器接变送器来实现。使用上述两种方案成本高、投资大。本文介绍一种低压双绕组电流互感器,它与ARTU-M32配合使用,可以实现对众多终端配电线路进行遥测的智能配电方案。该方案具有成本低、投资少、安装接线简便等优点,有利于低压智能配电的进一步推广和应用。So far, there are following methods to realize.system monitor for low-voltage distribution linewith many feeders. First, connect current transformer and multifunctional power monitoring instrumentation, together with 485 communication table, realizing multi-channel system monitor. Second, connect current transformer and transmitter. The above-mentioned methods have high cost and large investment. This paper introduces a low voltage dual-winding current transformer used in conjunction with ARTU-M32 to realize the intelligent l^ower distribution project of telemetering many terminal distribution line. Such a project has low cost and investment and is easy to install the wiring, boosting the promotion and application of low-voltage intelligent power distribution.
