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)(neng)(neng)(neng)電力儀(yi)表是一(yi)種具有(you)可編程(cheng)測(ce)量、顯示、數(shu)字通訊和電能(neng)(neng)(neng)(neng)脈沖(chong)變(bian)送輸出(chu)等多功能(neng)(neng)(neng)(neng)智(zhi)能(neng)(neng)(neng)(neng)儀(yi)表，具有(you)完成電量測(ce)量、電能(neng)(neng)(neng)(neng)計(ji)量、數(shu)據顯示、采(cai)集(ji)及傳輸等功能(neng)(neng)(neng)(neng)，廣泛應用于變(bian)電站自動(dong)化、配電自動(dong)化、智(zhi)能(neng)(neng)(neng)(neng)建筑、企業內部(bu)的電能(neng)(neng)(neng)(neng)測(ce)量、管理(li)、考核(he)等。

2、什么是電度表

電(dian)(dian)度表(biao)(biao)(biao)又叫電(dian)(dian)能(neng)表(biao)(biao)(biao)，簡稱電(dian)(dian)表(biao)(biao)(biao)，是(shi)測量(liang)電(dian)(dian)能(neng)的(de)儀(yi)表(biao)(biao)(biao)，廣(guang)泛(fan)應用(yong)于家庭用(yong)電(dian)(dian)、商(shang)業(ye)用(yong)電(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)(dian)度(du)表(biao)(biao)是一種(zhong)傳統的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)量(liang)(liang)儀表(biao)(biao)，通常采(cai)(cai)用鐵芯電(dian)(dian)(dian)(dian)(dian)流(liu)互感器(qi)和(he)電(dian)(dian)(dian)(dian)(dian)磁式電(dian)(dian)(dian)(dian)(dian)壓表(biao)(biao)實現(xian)測(ce)量(liang)(liang)。電(dian)(dian)(dian)(dian)(dian)度(du)表(biao)(biao)通過對(dui)電(dian)(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)積(ji)分來(lai)計(ji)算(suan)電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)(de)消耗量(liang)(liang)，因此它的(de)(de)測(ce)量(liang)(liang)精度(du)會受到電(dian)(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)(dian)流(liu)波形的(de)(de)影響(xiang)。多功能(neng)電(dian)(dian)(dian)(dian)(dian)力儀表(biao)(biao)則采(cai)(cai)用數(shu)字(zi)化技(ji)術實現(xian)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)量(liang)(liang)，其原理是通過對(dui)電(dian)(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)(dian)壓進(jin)行采(cai)(cai)樣和(he)數(shu)字(zi)處理，并對(dui)測(ce)量(liang)(liang)結果進(jin)行校正和(he)計(ji)算(suan)，可以實現(xian)高精度(du)的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)測(ce)量(liang)(liang)。

（2）功能區別

電(dian)(dian)(dian)度表(biao)(biao)(biao)通常(chang)只能測量電(dian)(dian)(dian)能的(de)消(xiao)(xiao)耗(hao)量，不能提(ti)供其他相關的(de)電(dian)(dian)(dian)參數，例如功(gong)率因數、電(dian)(dian)(dian)流諧(xie)波(bo)等信息。而多功(gong)能電(dian)(dian)(dian)力儀(yi)表(biao)(biao)(biao)不僅(jin)可以測量電(dian)(dian)(dian)能的(de)消(xiao)(xiao)耗(hao)量，還可以提(ti)供豐富的(de)電(dian)(dian)(dian)參數信息，例如電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓、功(gong)率因數、電(dian)(dian)(dian)流諧(xie)波(bo)、電(dian)(dian)(dian)壓諧(xie)波(bo)等。此外，多功(gong)能電(dian)(dian)(dian)力儀(yi)表(biao)(biao)(biao)還具有數據存儲、通信接(jie)口、報警功(gong)能等附加(jia)功(gong)能，可以更好(hao)地滿足不同用途(tu)和(he)應用場合的(de)需求。

（3）應用區別

電(dian)(dian)度表通(tong)常應(ying)用(yong)于家庭(ting)和小型商業用(yong)電(dian)(dian)量的計量，例如住宅、商鋪等。而多功(gong)能(neng)電(dian)(dian)力儀表則主要應(ying)用(yong)于工業生產線、電(dian)(dian)力系統等大型用(yong)電(dian)(dian)場合，其豐(feng)富的電(dian)(dian)參(can)數信息可(ke)以(yi)幫助用(yong)戶監測(ce)設(she)備運行狀態、優(you)化能(neng)源(yuan)管(guan)理，提高(gao)用(yong)電(dian)(dian)效率。

二、多功能電力儀表能當電度表嗎

多功能(neng)電(dian)力(li)儀表(biao)(biao)集成了電(dian)壓表(biao)(biao)、電(dian)流表(biao)(biao)、功率因數表(biao)(biao)、功率表(biao)(biao)、頻率表(biao)(biao)、電(dian)度表(biao)(biao)的(de)功能(neng)，可以(yi)在(zai)一個顯示(shi)(shi)界面上(shang)滾動顯示(shi)(shi)上(shang)述(shu)量(liang)值，它也是可以(yi)起(qi)到電(dian)度表(biao)(biao)電(dian)能(neng)測量(liang)的(de)作用(yong)的(de)，不過一般來說，不建議用(yong)多功能(neng)電(dian)力(li)儀表(biao)(biao)當電(dian)度表(biao)(biao)用(yong)。

多功能電力儀表是(shi)測(ce)量(liang)表(biao)，測(ce)量(liang)表(biao)僅作為(wei)顯(xian)示(shi)、監控(kong)等使用(yong)(yong)，可(ke)清零(ling)可(ke)復位可(ke)改(gai)變比，且(qie)測(ce)量(liang)表(biao)計接入(ru)的(de)CT、PT的(de)精(jing)度(du)級也都是(shi)測(ce)量(liang)級（一(yi)般(ban)是(shi)0.5級）；而電度(du)表(biao)屬于計量(liang)表(biao)，不可(ke)清零(ling)不可(ke)復位不可(ke)改(gai)變比（用(yong)(yong)計量(liang)表(biao)廠家只(zhi)提供給電力(li)公(gong)(gong)司(si)(si)的(de)專業(ye)軟件可(ke)以(yi)(yi)改(gai)，所以(yi)(yi)計量(liang)表(biao)需得到電力(li)公(gong)(gong)司(si)(si)的(de)認證），接入(ru)的(de)CT、PT的(de)精(jing)度(du)級也都是(shi)計量(liang)級（一(yi)般(ban)是(shi)0.2s或0.2級）。因此，不能把多(duo)功能電力(li)儀表(biao)當(dang)電度(du)表(biao)用(yong)(yong)。
