工作原理

DT(S)S238-7 WIFI型三相表(biao)主要由(you)電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)流采(cai)樣(yang)電(dian)(dian)(dian)路、專用電(dian)(dian)(dian)能(neng)(neng)(neng)計量芯片,CPU及LCD顯(xian)示等(deng)部分(fen)組(zu)成。電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)將采(cai)樣(yang)的電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流信號輸入(ru)到專用電(dian)(dian)(dian)能(neng)(neng)(neng)計量芯片，輸出電(dian)(dian)(dian)能(neng)(neng)(neng)脈沖信號，并由(you)LCD顯(xian)示電(dian)(dian)(dian)能(neng)(neng)(neng)，并通過WIFI接口實現遠(yuan)距離抄錄表(biao)內電(dian)(dian)(dian)能(neng)(neng)(neng)等(deng)數據。

電能表的安裝和接線

電能表應安(an)(an)裝在室內干燥、耐(nai)火(huo)、堅(jian)固的墻(qiang)上，安(an)(an)裝高度盡(jin)量為(wei)1.8米左右。

電能表(biao)的安裝尺(chi)寸采(cai)用35mm寬(kuan)度導軌(gui)安裝

電能表的接(jie)線應按照本表所提供的接(jie)線圖進行接(jie)線，盡(jin)量用銅線或銅線接(jie)頭引入。

使用及校驗

電(dian)能表(biao)出廠均校驗合格,并加鉛封(feng)。校驗時，通(tong)電(dian)后，電(dian)能表(biao)按標定(ding)的(de)(de)脈(mo)沖(chong)常數(shu)發出電(dian)能脈(mo)沖(chong)，為確保測(ce)量精度，對(dui)于(yu)不同(tong)的(de)(de)測(ce)試(shi)(shi)點(電(dian)流在0.05Ib～4Ib/6Ib范(fan)圍內(nei))在1～16個(ge)測(ce)試(shi)(shi)采(cai)集的(de)(de)脈(mo)沖(chong)數(shu)應(ying)隨著電(dian)流的(de)(de)增(zeng)加而(er)增(zeng)加，盡量在合理范(fan)圍內(nei)選取(qu)。

RS485通訊抄表應用(yong)

本電能表(biao)(biao)能通(tong)過(guo)其RS485接口實現遠(yuan)距離抄錄表(biao)(biao)內(nei)電能等數據。編碼格(ge)式、校驗和數據傳輸方式符(fu)合DL/T645標(biao)準要求(qiu)。每只表(biao)(biao)的表(biao)(biao)地(di)(di)址與表(biao)(biao)號一(yi)致,不(bu)足12位前面(mian)補0，通(tong)訊波(bo)(bo)特(te)率為1200bps—9600bps。采用奇偶校驗方式。如果選用MODBUS-RTU協議(yi)，默認波(bo)(bo)特(te)率為9600bps,通(tong)訊地(di)(di)址1.

運輸與貯存

(1) 電(dian)能表在運輸和(he)拆(chai)封時不(bu)應受(shou)到劇烈(lie)的(de)沖擊(ji)，并根據GB/T13384-2008《機電(dian)產(chan)品(pin)包裝通用技術條件》。
