摘(zhāi)要：本(běn)文(wén)介紹(shào)了(liǎo)安(ān)科瑞直(zhí)流電表DJSF1352在(zài)加(jiā)拿大(dà)光(guāng)伏係統中(zhōng)的應用(yòng)。主(zhǔ)要用(yòng)於(yú)光(guāng)伏(fú)係統(tǒng)中(zhōng)的電(diàn)流的計量，配(pèi)合(hé)分(fēn)流(liú)器(qì)對(duì)電流進(jìn)行計量(liáng)。

  Abstract: This article introduces the application of Acrel DC meters in PV system in Canada.The device is measuring current,together with shunt.

  1.項目概述(shù)：

  Project Overview

  該公司(sī)位於加(jiā)拿大(dà)，公司(sī)主要(yào)從事(shì)光伏這一行業。客(kè)戶想要(yào)使(shǐ)用直(zhí)流(liú)電表(biǎo)DJSF1352-RN和分流器，用於(yú)光伏(fú)係(xì)統(tǒng)電流電壓(yā)的(dí)監測(cè)計(jì)量(liáng)以及利(lì)用直流表的開(kāi)關(guān)量(liáng)功能進行控製(zhì)。

  The company is located in Canada, and the company is mainly engaged in the photovoltaic industry. The customer wants to use the DC meter DJSF1352-RN and shunt to monitor and measure the current and voltage of the photovoltaic system and use the switch function of the DC meter for control.

  2.DJSF1352-RN係列(liè)直流電能表(biǎo)的介紹

  DJSF1352-RN Series DC Energy Meters

  DJSF1352-RN係列直流電(diàn)能表(biǎo)是(shì)針(zhēn)對直流(liú)屏，太陽能(néng)供電，電(diàn)信基(jī)站，充電樁(zhuāng)等應(yīng)用(yòng)場合而(ér)設(shè)計的(dí)，該係列儀(yí)表可測(cè)量直(zhí)流(liú)係(xì)統中的電壓(yā)，電(diàn)流，功(gōng)率(shuài)，正(zhèng)向與(yǔ)反向(xiàng)電能。既(jì)可用於(yú)本地顯示，又能(néng)與工控設(shè)備(bèi)，計算機連接，組(zǔ)成測控(kòng)係統(tǒng)。同時它具(jù)有(yǒu)多種外圍(wéi)接(jiē)口功能可供(gōng)用戶選擇：帶(dài)有RS-485通(tōng)訊(xùn)接口，采用(yòng)Modbus-RTU協議；可(kě)帶繼電(diàn)器(qì)報警(jǐng)輸出(chū)，開(kāi)關量(liáng)輸入/輸出。根(gēn)據不同(tóng)要求，通過儀表(biǎo)麵板按(àn)鍵(jiàn)，對變比，通(tōng)訊(xùn)進(jìn)行(háng)設(shè)置與控(kòng)製。

  DJSF1352-RN series intelligent DC energy meter is designed for applications such as DC panels, solar power,telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power,forward and reverse power in DC system. It can be used for local display, and connected with industrial control

  equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output. According to different requirements, through the instrument panel keys, you can set the ratio, communication parameters.
