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(duo)功能(neng)電(dian)(dian)力儀表(biao)(biao)是一種具有可(ke)編(bian)程測量(liang)(liang)、顯(xian)示、數字通訊和(he)電(dian)(dian)能(neng)脈沖變(bian)送(song)輸(shu)出等(deng)多(duo)功能(neng)智(zhi)能(neng)儀表(biao)(biao)，具有完(wan)成電(dian)(dian)量(liang)(liang)測量(liang)(liang)、電(dian)(dian)能(neng)計量(liang)(liang)、數據顯(xian)示、采集及傳輸(shu)等(deng)功能(neng)，廣泛應用于變(bian)電(dian)(dian)站自動(dong)化、配電(dian)(dian)自動(dong)化、智(zhi)能(neng)建筑、企業(ye)內部(bu)的電(dian)(dian)能(neng)測量(liang)(liang)、管(guan)理(li)、考核等(deng)。

2、什么是電度表

電(dian)度表(biao)又叫電(dian)能表(biao)，簡(jian)稱(cheng)電(dian)表(biao)，是(shi)測(ce)量電(dian)能的儀表(biao)，廣泛應用于家(jia)庭(ting)用電(dian)、商業用電(dian)等(deng)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)度(du)(du)表(biao)是一種(zhong)傳(chuan)統的電(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)儀(yi)表(biao)，通常(chang)采(cai)用鐵芯電(dian)(dian)(dian)流互感器和電(dian)(dian)(dian)磁式電(dian)(dian)(dian)壓(ya)(ya)(ya)表(biao)實現測(ce)(ce)量(liang)(liang)。電(dian)(dian)(dian)度(du)(du)表(biao)通過對(dui)電(dian)(dian)(dian)流和電(dian)(dian)(dian)壓(ya)(ya)(ya)的積(ji)分來計(ji)算電(dian)(dian)(dian)能(neng)的消耗量(liang)(liang)，因此它的測(ce)(ce)量(liang)(liang)精度(du)(du)會受(shou)到電(dian)(dian)(dian)壓(ya)(ya)(ya)和電(dian)(dian)(dian)流波(bo)形的影響。多功(gong)能(neng)電(dian)(dian)(dian)力儀(yi)表(biao)則采(cai)用數字化技術實現電(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)，其原理是通過對(dui)電(dian)(dian)(dian)流和電(dian)(dian)(dian)壓(ya)(ya)(ya)進行采(cai)樣(yang)和數字處理，并對(dui)測(ce)(ce)量(liang)(liang)結果進行校正(zheng)和計(ji)算，可以實現高精度(du)(du)的電(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)。

（2）功能區別

電(dian)(dian)(dian)(dian)度表通常只能測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)能的消耗(hao)(hao)量(liang)(liang)，不能提(ti)供其他相關(guan)的電(dian)(dian)(dian)(dian)參數，例如功(gong)率因數、電(dian)(dian)(dian)(dian)流諧(xie)(xie)波等(deng)信(xin)息。而多功(gong)能電(dian)(dian)(dian)(dian)力儀(yi)表不僅可以(yi)(yi)測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)能的消耗(hao)(hao)量(liang)(liang)，還可以(yi)(yi)提(ti)供豐富的電(dian)(dian)(dian)(dian)參數信(xin)息，例如電(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)壓、功(gong)率因數、電(dian)(dian)(dian)(dian)流諧(xie)(xie)波、電(dian)(dian)(dian)(dian)壓諧(xie)(xie)波等(deng)。此外(wai)，多功(gong)能電(dian)(dian)(dian)(dian)力儀(yi)表還具有數據存(cun)儲、通信(xin)接口、報(bao)警功(gong)能等(deng)附加功(gong)能，可以(yi)(yi)更好地滿足不同(tong)用途和應用場合的需(xu)求。

（3）應用區別

電(dian)(dian)度(du)表(biao)(biao)通常應用(yong)(yong)(yong)于家庭和小型商業(ye)(ye)用(yong)(yong)(yong)電(dian)(dian)量的(de)計量，例(li)如住宅、商鋪等(deng)。而多功(gong)能電(dian)(dian)力儀表(biao)(biao)則主要(yao)應用(yong)(yong)(yong)于工業(ye)(ye)生產線(xian)、電(dian)(dian)力系統等(deng)大型用(yong)(yong)(yong)電(dian)(dian)場合，其豐富的(de)電(dian)(dian)參數信息可(ke)以幫助用(yong)(yong)(yong)戶監(jian)測設備運行狀態、優化(hua)能源(yuan)管(guan)理，提高用(yong)(yong)(yong)電(dian)(dian)效率(lv)。

二、多功能電力儀表能當電度表嗎

多(duo)(duo)功(gong)能(neng)電(dian)力儀表(biao)(biao)(biao)集(ji)成(cheng)了(le)電(dian)壓表(biao)(biao)(biao)、電(dian)流表(biao)(biao)(biao)、功(gong)率因數表(biao)(biao)(biao)、功(gong)率表(biao)(biao)(biao)、頻率表(biao)(biao)(biao)、電(dian)度表(biao)(biao)(biao)的(de)功(gong)能(neng)，可以在一個顯(xian)(xian)示(shi)界面上滾動顯(xian)(xian)示(shi)上述(shu)量值，它(ta)也是可以起到電(dian)度表(biao)(biao)(biao)電(dian)能(neng)測量的(de)作(zuo)用的(de)，不過一般來說(shuo)，不建議用多(duo)(duo)功(gong)能(neng)電(dian)力儀表(biao)(biao)(biao)當電(dian)度表(biao)(biao)(biao)用。

多功能電力儀表是測(ce)量表(biao)(biao)，測(ce)量表(biao)(biao)僅作為顯示、監控(kong)等使用，可(ke)清零(ling)可(ke)復位可(ke)改(gai)變(bian)比(bi)，且測(ce)量表(biao)(biao)計(ji)(ji)接(jie)入的(de)CT、PT的(de)精(jing)度(du)級(ji)也(ye)都是測(ce)量級(ji)（一(yi)(yi)般是0.5級(ji)）；而(er)電(dian)度(du)表(biao)(biao)屬于計(ji)(ji)量表(biao)(biao)，不可(ke)清零(ling)不可(ke)復位不可(ke)改(gai)變(bian)比(bi)（用計(ji)(ji)量表(biao)(biao)廠家只提(ti)供給電(dian)力(li)公司的(de)專業軟件(jian)可(ke)以改(gai)，所以計(ji)(ji)量表(biao)(biao)需得到電(dian)力(li)公司的(de)認證），接(jie)入的(de)CT、PT的(de)精(jing)度(du)級(ji)也(ye)都是計(ji)(ji)量級(ji)（一(yi)(yi)般是0.2s或0.2級(ji)）。因(yin)此(ci)，不能把多功能電(dian)力(li)儀表(biao)(biao)當(dang)電(dian)度(du)表(biao)(biao)用。
