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

多功能(neng)電(dian)力儀表(biao)是一(yi)種(zhong)具有可(ke)編程測(ce)量、顯示、數(shu)字通訊和電(dian)能(neng)脈沖變(bian)送輸(shu)出等(deng)多功能(neng)智(zhi)能(neng)儀表(biao)，具有完成(cheng)電(dian)量測(ce)量、電(dian)能(neng)計量、數(shu)據顯示、采(cai)集及傳輸(shu)等(deng)功能(neng)，廣(guang)泛(fan)應用于變(bian)電(dian)站(zhan)自動化、配電(dian)自動化、智(zhi)能(neng)建(jian)筑(zhu)、企業內部(bu)的電(dian)能(neng)測(ce)量、管理、考核等(deng)。

2、什么是電度表

電度表又叫(jiao)電能表，簡稱(cheng)電表，是(shi)測量電能的儀表，廣泛應用(yong)(yong)于家庭用(yong)(yong)電、商業用(yong)(yong)電等方面。

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)是一種傳(chuan)統的(de)電(dian)(dian)(dian)(dian)能測量(liang)(liang)儀表(biao)，通常采(cai)用鐵芯電(dian)(dian)(dian)(dian)流(liu)互感(gan)器和(he)電(dian)(dian)(dian)(dian)磁(ci)式電(dian)(dian)(dian)(dian)壓(ya)表(biao)實現測量(liang)(liang)。電(dian)(dian)(dian)(dian)度(du)表(biao)通過對(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)壓(ya)的(de)積分來計(ji)算電(dian)(dian)(dian)(dian)能的(de)消耗量(liang)(liang)，因此它的(de)測量(liang)(liang)精(jing)度(du)會受到電(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)流(liu)波形(xing)的(de)影(ying)響。多功能電(dian)(dian)(dian)(dian)力儀表(biao)則采(cai)用數字化技術實現電(dian)(dian)(dian)(dian)能測量(liang)(liang)，其原(yuan)理(li)是通過對(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)壓(ya)進(jin)行采(cai)樣和(he)數字處理(li)，并對(dui)測量(liang)(liang)結(jie)果(guo)進(jin)行校正和(he)計(ji)算，可以(yi)實現高精(jing)度(du)的(de)電(dian)(dian)(dian)(dian)能測量(liang)(liang)。

（2）功能區別

電(dian)(dian)(dian)度表(biao)通常只能測量電(dian)(dian)(dian)能的(de)消耗量，不(bu)能提(ti)供其他相關的(de)電(dian)(dian)(dian)參數(shu)，例(li)(li)如功(gong)(gong)率(lv)因數(shu)、電(dian)(dian)(dian)流(liu)諧波(bo)等信息。而多(duo)功(gong)(gong)能電(dian)(dian)(dian)力儀(yi)表(biao)不(bu)僅可以測量電(dian)(dian)(dian)能的(de)消耗量，還(huan)可以提(ti)供豐富的(de)電(dian)(dian)(dian)參數(shu)信息，例(li)(li)如電(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)壓(ya)、功(gong)(gong)率(lv)因數(shu)、電(dian)(dian)(dian)流(liu)諧波(bo)、電(dian)(dian)(dian)壓(ya)諧波(bo)等。此外，多(duo)功(gong)(gong)能電(dian)(dian)(dian)力儀(yi)表(biao)還(huan)具有數(shu)據存儲、通信接口、報警功(gong)(gong)能等附加功(gong)(gong)能，可以更(geng)好(hao)地滿(man)足不(bu)同用(yong)(yong)途(tu)和應用(yong)(yong)場(chang)合的(de)需求。

（3）應用區別

電(dian)(dian)度表通(tong)常應用(yong)(yong)于家庭和小型商業用(yong)(yong)電(dian)(dian)量的計量，例如住宅、商鋪(pu)等。而多功能(neng)電(dian)(dian)力(li)儀表則主要應用(yong)(yong)于工業生(sheng)產(chan)線、電(dian)(dian)力(li)系統等大型用(yong)(yong)電(dian)(dian)場合，其豐(feng)富的電(dian)(dian)參數(shu)信(xin)息可以幫助(zhu)用(yong)(yong)戶監測設備運行狀(zhuang)態、優(you)化能(neng)源管理，提高用(yong)(yong)電(dian)(dian)效率。

二、多功能電力儀表能當電度表嗎

多功(gong)能(neng)電(dian)力儀表(biao)集成(cheng)了電(dian)壓表(biao)、電(dian)流表(biao)、功(gong)率因數表(biao)、功(gong)率表(biao)、頻率表(biao)、電(dian)度表(biao)的(de)功(gong)能(neng)，可以在(zai)一個顯示界面上滾動(dong)顯示上述(shu)量值，它也是可以起到(dao)電(dian)度表(biao)電(dian)能(neng)測量的(de)作用(yong)的(de)，不過一般(ban)來說，不建議用(yong)多功(gong)能(neng)電(dian)力儀表(biao)當電(dian)度表(biao)用(yong)。

多功能電力儀表是(shi)(shi)(shi)測(ce)量(liang)表，測(ce)量(liang)表僅作(zuo)為(wei)顯示(shi)、監控等使用，可清零(ling)可復(fu)位可改變(bian)比(bi)，且測(ce)量(liang)表計(ji)接入的(de)(de)CT、PT的(de)(de)精度(du)級也(ye)(ye)都是(shi)(shi)(shi)測(ce)量(liang)級（一般是(shi)(shi)(shi)0.5級）；而電度(du)表屬于計(ji)量(liang)表，不(bu)可清零(ling)不(bu)可復(fu)位不(bu)可改變(bian)比(bi)（用計(ji)量(liang)表廠家(jia)只提供給電力公司的(de)(de)專業(ye)軟件可以(yi)改，所以(yi)計(ji)量(liang)表需得到電力公司的(de)(de)認證(zheng)），接入的(de)(de)CT、PT的(de)(de)精度(du)級也(ye)(ye)都是(shi)(shi)(shi)計(ji)量(liang)級（一般是(shi)(shi)(shi)0.2s或0.2級）。因此，不(bu)能(neng)把多功能(neng)電力儀表當電度(du)表用。
