  1.项目概述Project Overview

  该公司位于保加利亚，公司主要在保加利亚及周边国家从事小型光伏发电中心项目的设计/安装施工/维护等业务。客户想要使用交流电表APM801、APM810等和互感器，用于光伏系统交流侧电流电压的监测计量、通讯以及利用APM电表的开关量功能进行控制。

  The company is located in Bulgaria. The company is mainly engaged in the design / installation, construction / maintenance of small photovoltaic power generation center projects in Bulgaria and surrounding countries. The customer wants to use AC meters apm801, apm810 and mutual inductors for monitoring, metering and communication of current and voltage at the AC side of photovoltaic system, and control by using the switching value function of APM meter.

  2.APM系列仪表简介APM Series Energy Meters

  ACREL的APM系列功率表是根据IEC标准设计并与国际先进技术同步的功率表。

  APM系列电能表具有全功率测量、电能统计、电能质量分析和网络通信等功能，主要用于供电网络质量的综合监测。

  本系列仪表采用模块化设计，具有丰富的外部DI/DO模块、AI/AO模块、带T-Flash（TF）卡的事件记录（SOE）模块、网络通信模块、温湿度测量模块功能，可实现电路全功率测量和开关状态监测，具有以太网接口的双RS485可实现RS485主站的数据拷贝，无需进行数据交换。PROFIBUS-DP接口可实现高速数据传输和联网功能。

  APM series power meters of ACREL are power meters that are designed according to IEC standards and synchronized with international advanced technology.

  APM series meters have full power measurement, energy statistics, analysis of power quality and network communications and other functions, are mainly used for comprehensive monitoring of the quality of power supply network.

  This series of meters use a modular design, with a rich function of the external DI / DO module, AI / AO module, event recording (SOE) module with T-Flash (TF) card, network communication module, Temperature and humidity measurement module, can achieve full power measurement of electrical circuit and monitoring of switch status, Dual RS485 with Ethernet interface can realize data copying of RS485 master station, eliminating the need for data switching exchange. PROFIBUS-DP interface can realize high-speed data transmission and networking function.
