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

多功能電力(li)儀表是一種具(ju)(ju)有(you)可編程測量(liang)、顯示、數(shu)(shu)字通訊和電能脈沖變送輸(shu)出(chu)等多功能智能儀表，具(ju)(ju)有(you)完成電量(liang)測量(liang)、電能計量(liang)、數(shu)(shu)據顯示、采集及傳輸(shu)等功能，廣泛應用于變電站自(zi)(zi)動化(hua)、配電自(zi)(zi)動化(hua)、智能建筑(zhu)、企業內(nei)部的電能測量(liang)、管(guan)理、考核等。

2、什么是電度表

電度表(biao)又叫(jiao)電能表(biao)，簡(jian)稱(cheng)電表(biao)，是測(ce)量(liang)電能的(de)儀表(biao)，廣泛應用于(yu)家庭(ting)用電、商業用電等(deng)方面(mian)。

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)(dian)度表是(shi)一種傳統的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)(ce)量儀表，通常采用鐵(tie)芯電(dian)(dian)(dian)(dian)(dian)流互(hu)感器和(he)電(dian)(dian)(dian)(dian)(dian)磁式電(dian)(dian)(dian)(dian)(dian)壓表實(shi)(shi)現(xian)測(ce)(ce)(ce)量。電(dian)(dian)(dian)(dian)(dian)度表通過對(dui)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)壓的(de)積分(fen)來計(ji)算(suan)電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)消耗量，因此它(ta)的(de)測(ce)(ce)(ce)量精度會受到(dao)電(dian)(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)(dian)流波形(xing)的(de)影響。多功能(neng)電(dian)(dian)(dian)(dian)(dian)力儀表則采用數字化技術(shu)實(shi)(shi)現(xian)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)(ce)量，其原理是(shi)通過對(dui)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)壓進行(xing)采樣(yang)和(he)數字處理，并對(dui)測(ce)(ce)(ce)量結(jie)果進行(xing)校正和(he)計(ji)算(suan)，可以實(shi)(shi)現(xian)高精度的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)(ce)量。

（2）功能區別

電(dian)(dian)(dian)度表通常(chang)只能(neng)(neng)(neng)測(ce)量電(dian)(dian)(dian)能(neng)(neng)(neng)的(de)(de)消耗量，不能(neng)(neng)(neng)提(ti)供其他相關的(de)(de)電(dian)(dian)(dian)參數(shu)，例如功率(lv)因數(shu)、電(dian)(dian)(dian)流(liu)諧(xie)(xie)波(bo)(bo)等(deng)(deng)信息。而多功能(neng)(neng)(neng)電(dian)(dian)(dian)力(li)(li)儀表不僅可以測(ce)量電(dian)(dian)(dian)能(neng)(neng)(neng)的(de)(de)消耗量，還可以提(ti)供豐富的(de)(de)電(dian)(dian)(dian)參數(shu)信息，例如電(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)壓、功率(lv)因數(shu)、電(dian)(dian)(dian)流(liu)諧(xie)(xie)波(bo)(bo)、電(dian)(dian)(dian)壓諧(xie)(xie)波(bo)(bo)等(deng)(deng)。此外，多功能(neng)(neng)(neng)電(dian)(dian)(dian)力(li)(li)儀表還具有數(shu)據存(cun)儲、通信接口、報警(jing)功能(neng)(neng)(neng)等(deng)(deng)附加(jia)功能(neng)(neng)(neng)，可以更好地滿足不同用途和(he)應用場(chang)合的(de)(de)需求。

（3）應用區別

電(dian)(dian)(dian)度表通常(chang)應(ying)用(yong)(yong)(yong)于(yu)家庭和小型商業用(yong)(yong)(yong)電(dian)(dian)(dian)量(liang)的計(ji)量(liang)，例如住(zhu)宅、商鋪等(deng)。而多功能(neng)電(dian)(dian)(dian)力儀表則主要應(ying)用(yong)(yong)(yong)于(yu)工業生(sheng)產(chan)線、電(dian)(dian)(dian)力系統(tong)等(deng)大型用(yong)(yong)(yong)電(dian)(dian)(dian)場(chang)合，其豐富的電(dian)(dian)(dian)參(can)數信息可以(yi)幫助用(yong)(yong)(yong)戶監測(ce)設備運行狀態、優化能(neng)源管(guan)理(li)，提(ti)高(gao)用(yong)(yong)(yong)電(dian)(dian)(dian)效率。

二、多功能電力儀表能當電度表嗎

多功(gong)(gong)能(neng)電(dian)(dian)力儀表(biao)(biao)集成了電(dian)(dian)壓(ya)表(biao)(biao)、電(dian)(dian)流表(biao)(biao)、功(gong)(gong)率因數表(biao)(biao)、功(gong)(gong)率表(biao)(biao)、頻率表(biao)(biao)、電(dian)(dian)度(du)表(biao)(biao)的(de)功(gong)(gong)能(neng)，可以(yi)在一個顯(xian)示(shi)界面上滾動顯(xian)示(shi)上述量值(zhi)，它也是可以(yi)起到電(dian)(dian)度(du)表(biao)(biao)電(dian)(dian)能(neng)測量的(de)作用的(de)，不(bu)過(guo)一般來說，不(bu)建議(yi)用多功(gong)(gong)能(neng)電(dian)(dian)力儀表(biao)(biao)當電(dian)(dian)度(du)表(biao)(biao)用。

多功能電力儀表是(shi)(shi)測(ce)(ce)量表，測(ce)(ce)量表僅作為顯示、監(jian)控(kong)等使(shi)用，可(ke)(ke)清零(ling)(ling)可(ke)(ke)復位(wei)可(ke)(ke)改(gai)變(bian)比，且測(ce)(ce)量表計(ji)接入的(de)CT、PT的(de)精度級(ji)(ji)(ji)也(ye)都(dou)是(shi)(shi)測(ce)(ce)量級(ji)(ji)(ji)（一(yi)(yi)般(ban)是(shi)(shi)0.5級(ji)(ji)(ji)）；而電(dian)度表屬于(yu)計(ji)量表，不(bu)可(ke)(ke)清零(ling)(ling)不(bu)可(ke)(ke)復位(wei)不(bu)可(ke)(ke)改(gai)變(bian)比（用計(ji)量表廠家只提供(gong)給電(dian)力(li)公(gong)司的(de)專業(ye)軟件可(ke)(ke)以改(gai)，所(suo)以計(ji)量表需得到(dao)電(dian)力(li)公(gong)司的(de)認證），接入的(de)CT、PT的(de)精度級(ji)(ji)(ji)也(ye)都(dou)是(shi)(shi)計(ji)量級(ji)(ji)(ji)（一(yi)(yi)般(ban)是(shi)(shi)0.2s或0.2級(ji)(ji)(ji)）。因此，不(bu)能(neng)把(ba)多功能(neng)電(dian)力(li)儀表當(dang)電(dian)度表用。
