1.项目概述:Project Overview
该公司位于沙特,公司主要在当地从事小型光伏发电项目的安装施工与维护等业务。客户想要使用直流电表,用于光伏系统中直流侧电流电压的监测计量、通讯,要求电表具有两路直流电能测量的功能。
The company is located in Saudi Arabia. The company is mainly engaged in installation, construction and maintenance of small photovoltaic power generation center projects in Bulgaria and surrounding countries. The customer wants to use DC meters and hall sensors or current shunts for monitoring, metering and communication of current and voltage at the DC side of photovoltaic system, and demands that the DC energy meter would be able to measure two channels of DC circuits.
2.DJSF1352-RN/D仪表简介 DJSF1352-RN/D DC Energy Meters
DJSF1352-RN导轨式直流电能表带有双路直流输入,主要针对网络基站、直流充电桩、太阳能光伏等应用场合而设计,该系列仪表可测量直流系统中的电压、电流、功率以及正反向电能等。在实际使用现场,即可计量总电能,又可计量规定时间段内的电能。检测的结果既可用于本地显示,又能与工控设备、计算机连接,组成测控系统。
仪表可具有红外通讯接口和RS-485通讯接口,同时支持Modbus-RTU协议和DLT645-97(07)协议;可带继电器预警输出和开关量输入功能;根据不同要求,通过仪表面板按键,对变比、预警、通讯进行设置;具有开关量事件记录(Modbus协议)、编程和事件设置记录(645协议)、数据瞬时和定时冻结功能(645协议)、电压电流功率峰值、谷值记录功能。
DJSF1352-RN rail-mounted DC power meter with double DC input channels, designed for telecommunications base stations, DC charging piles, solar photovoltaic and other applications, this series of meters can measure the voltage, current, power and forward and reverse energy and so on in the DC system.The actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.
The meter can have infrared communication interface and RS-485 communication interface, and supports Modbus-RTU protocol and DLT645-97 (07) protocol at the same time.The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), programming and event setting records (645 protocol), instantaneous and timing freeze function of data (645 protocol), maximum and minimum value recording function of voltage and current power.
3.型号及功能介绍 Type and Function Description
Note:when dual DC input(D)function is selected,if Hall current sensor input is used in
current channel,a power supply module shall be provided to supply power to the second Hall sensor;if D function is not provided,the built-in power supply of elecctric meter can be used.
4.客户特殊需求Requirements from Customer
4.1 以下是客户现场太阳能电板参数:
The following are the customer's on-site solar panel parameters:
4.2 两路直流电能计量
客户要求直流表具有两路直流电能计量功能,因此需要搭配两个分流器。
The customer requires a DC meter with two channels of direct current metering function, so two current shunts are needed to work with the meter.
