一、多功能電力儀表和電度表的區別是什么

1、什么是多功能電力儀表

多功(gong)能電(dian)(dian)力(li)儀表是一(yi)種具有可編程測量(liang)、顯示、數(shu)(shu)字通訊和電(dian)(dian)能脈沖變送輸(shu)出等(deng)多功(gong)能智能儀表，具有完成電(dian)(dian)量(liang)測量(liang)、電(dian)(dian)能計量(liang)、數(shu)(shu)據顯示、采集(ji)及傳輸(shu)等(deng)功(gong)能，廣(guang)泛應用于變電(dian)(dian)站自動(dong)化、配電(dian)(dian)自動(dong)化、智能建筑、企(qi)業內部的電(dian)(dian)能測量(liang)、管理、考核等(deng)。

2、什么是電度表

電(dian)(dian)(dian)度表(biao)又叫電(dian)(dian)(dian)能(neng)表(biao)，簡稱(cheng)電(dian)(dian)(dian)表(biao)，是測量(liang)電(dian)(dian)(dian)能(neng)的儀表(biao)，廣泛應用(yong)于家庭用(yong)電(dian)(dian)(dian)、商業(ye)用(yong)電(dian)(dian)(dian)等方面。

3、多功能電力儀表和電度表的區別

（1）原理區別

電(dian)(dian)(dian)(dian)度(du)表(biao)(biao)(biao)是(shi)一(yi)種傳統(tong)的(de)電(dian)(dian)(dian)(dian)能(neng)測量(liang)儀(yi)表(biao)(biao)(biao)，通(tong)常(chang)采(cai)用鐵芯(xin)電(dian)(dian)(dian)(dian)流互感(gan)器和電(dian)(dian)(dian)(dian)磁(ci)式(shi)電(dian)(dian)(dian)(dian)壓表(biao)(biao)(biao)實現(xian)(xian)測量(liang)。電(dian)(dian)(dian)(dian)度(du)表(biao)(biao)(biao)通(tong)過(guo)(guo)對電(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)壓的(de)積分來計(ji)算電(dian)(dian)(dian)(dian)能(neng)的(de)消耗(hao)量(liang)，因此它的(de)測量(liang)精(jing)度(du)會受到電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)流波形的(de)影響。多功能(neng)電(dian)(dian)(dian)(dian)力儀(yi)表(biao)(biao)(biao)則采(cai)用數字化技術實現(xian)(xian)電(dian)(dian)(dian)(dian)能(neng)測量(liang)，其原(yuan)理是(shi)通(tong)過(guo)(guo)對電(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)壓進行(xing)采(cai)樣和數字處理，并對測量(liang)結果(guo)進行(xing)校正和計(ji)算，可以(yi)實現(xian)(xian)高精(jing)度(du)的(de)電(dian)(dian)(dian)(dian)能(neng)測量(liang)。

（2）功能區別

電(dian)(dian)(dian)(dian)度表(biao)(biao)通常只(zhi)能(neng)(neng)測(ce)量(liang)電(dian)(dian)(dian)(dian)能(neng)(neng)的消(xiao)耗(hao)量(liang)，不(bu)能(neng)(neng)提供其(qi)他(ta)相關的電(dian)(dian)(dian)(dian)參數(shu)，例如功(gong)(gong)率(lv)因數(shu)、電(dian)(dian)(dian)(dian)流諧波(bo)等信(xin)息。而多功(gong)(gong)能(neng)(neng)電(dian)(dian)(dian)(dian)力儀表(biao)(biao)不(bu)僅可以測(ce)量(liang)電(dian)(dian)(dian)(dian)能(neng)(neng)的消(xiao)耗(hao)量(liang)，還(huan)可以提供豐富的電(dian)(dian)(dian)(dian)參數(shu)信(xin)息，例如電(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)壓(ya)、功(gong)(gong)率(lv)因數(shu)、電(dian)(dian)(dian)(dian)流諧波(bo)、電(dian)(dian)(dian)(dian)壓(ya)諧波(bo)等。此(ci)外，多功(gong)(gong)能(neng)(neng)電(dian)(dian)(dian)(dian)力儀表(biao)(biao)還(huan)具有數(shu)據存儲(chu)、通信(xin)接口、報警功(gong)(gong)能(neng)(neng)等附加功(gong)(gong)能(neng)(neng)，可以更好地滿足不(bu)同用途(tu)和應用場合的需求。

（3）應用區別

電度表通常應用(yong)(yong)(yong)于(yu)家庭和小型商業用(yong)(yong)(yong)電量的計量，例如住(zhu)宅(zhai)、商鋪等(deng)。而多功(gong)能(neng)電力(li)儀表則主要應用(yong)(yong)(yong)于(yu)工業生產(chan)線、電力(li)系統等(deng)大型用(yong)(yong)(yong)電場(chang)合(he)，其豐富的電參數(shu)信(xin)息(xi)可以幫助用(yong)(yong)(yong)戶監測(ce)設備運(yun)行狀態(tai)、優化(hua)能(neng)源管(guan)理，提(ti)高用(yong)(yong)(yong)電效率(lv)。

二、多功能電力儀表能當電度表嗎

多(duo)功(gong)(gong)能(neng)電(dian)(dian)(dian)力(li)儀表(biao)(biao)(biao)集(ji)成了電(dian)(dian)(dian)壓表(biao)(biao)(biao)、電(dian)(dian)(dian)流(liu)表(biao)(biao)(biao)、功(gong)(gong)率因數表(biao)(biao)(biao)、功(gong)(gong)率表(biao)(biao)(biao)、頻率表(biao)(biao)(biao)、電(dian)(dian)(dian)度表(biao)(biao)(biao)的(de)功(gong)(gong)能(neng)，可(ke)以(yi)在一個顯示界面上滾(gun)動(dong)顯示上述量(liang)值，它也是可(ke)以(yi)起到電(dian)(dian)(dian)度表(biao)(biao)(biao)電(dian)(dian)(dian)能(neng)測量(liang)的(de)作用(yong)的(de)，不過一般來說(shuo)，不建議用(yong)多(duo)功(gong)(gong)能(neng)電(dian)(dian)(dian)力(li)儀表(biao)(biao)(biao)當電(dian)(dian)(dian)度表(biao)(biao)(biao)用(yong)。

多功能電力儀表是測(ce)(ce)量表(biao)(biao)，測(ce)(ce)量表(biao)(biao)僅(jin)作(zuo)為顯(xian)示、監控等使用，可(ke)清零可(ke)復(fu)位(wei)可(ke)改變(bian)比(bi)，且測(ce)(ce)量表(biao)(biao)計(ji)(ji)接入(ru)(ru)的(de)CT、PT的(de)精度級(ji)也都是測(ce)(ce)量級(ji)（一般是0.5級(ji)）；而(er)電(dian)度表(biao)(biao)屬于計(ji)(ji)量表(biao)(biao)，不可(ke)清零不可(ke)復(fu)位(wei)不可(ke)改變(bian)比(bi)（用計(ji)(ji)量表(biao)(biao)廠家只提供給電(dian)力公(gong)司的(de)專業軟件可(ke)以(yi)改，所以(yi)計(ji)(ji)量表(biao)(biao)需得到電(dian)力公(gong)司的(de)認證(zheng)），接入(ru)(ru)的(de)CT、PT的(de)精度級(ji)也都是計(ji)(ji)量級(ji)（一般是0.2s或0.2級(ji)）。因此(ci)，不能把多功能電(dian)力儀表(biao)(biao)當(dang)電(dian)度表(biao)(biao)用。
