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(gong)能(neng)(neng)電(dian)(dian)力儀表是一種具(ju)有可編程測量、顯(xian)示(shi)、數字通訊和電(dian)(dian)能(neng)(neng)脈(mo)沖變(bian)送輸出等多(duo)功(gong)能(neng)(neng)智能(neng)(neng)儀表，具(ju)有完成電(dian)(dian)量測量、電(dian)(dian)能(neng)(neng)計量、數據顯(xian)示(shi)、采(cai)集及傳輸等功(gong)能(neng)(neng)，廣泛應用于(yu)變(bian)電(dian)(dian)站自動化、配電(dian)(dian)自動化、智能(neng)(neng)建(jian)筑(zhu)、企業內部(bu)的電(dian)(dian)能(neng)(neng)測量、管(guan)理、考核(he)等。

2、什么是電度表

電(dian)度表(biao)又叫電(dian)能表(biao)，簡稱電(dian)表(biao)，是測量電(dian)能的儀表(biao)，廣泛(fan)應(ying)用于家庭用電(dian)、商業用電(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)(biao)是一種傳統的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)量儀表(biao)(biao)(biao)，通常采(cai)用(yong)鐵芯電(dian)(dian)(dian)(dian)(dian)流互感器和(he)電(dian)(dian)(dian)(dian)(dian)磁式(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)(biao)實(shi)現測(ce)量。電(dian)(dian)(dian)(dian)(dian)度(du)表(biao)(biao)(biao)通過(guo)(guo)對(dui)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)積分來計算電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)(de)消耗量，因此它(ta)的(de)(de)測(ce)量精度(du)會受到(dao)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)(dian)流波形的(de)(de)影響。多功能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)力儀表(biao)(biao)(biao)則(ze)采(cai)用(yong)數(shu)字化技術實(shi)現電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)量，其原理是通過(guo)(guo)對(dui)電(dian)(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)(dian)壓(ya)進(jin)行采(cai)樣和(he)數(shu)字處理，并對(dui)測(ce)量結(jie)果進(jin)行校正(zheng)和(he)計算，可(ke)以實(shi)現高精度(du)的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)量。

（2）功能區別

電(dian)(dian)(dian)度(du)表通(tong)常(chang)只(zhi)能(neng)(neng)測(ce)量電(dian)(dian)(dian)能(neng)(neng)的消(xiao)耗量，不能(neng)(neng)提供其他(ta)相關的電(dian)(dian)(dian)參(can)數(shu)，例如(ru)功(gong)率因數(shu)、電(dian)(dian)(dian)流(liu)諧(xie)波等(deng)信息。而多(duo)功(gong)能(neng)(neng)電(dian)(dian)(dian)力儀表不僅可以測(ce)量電(dian)(dian)(dian)能(neng)(neng)的消(xiao)耗量，還可以提供豐(feng)富的電(dian)(dian)(dian)參(can)數(shu)信息，例如(ru)電(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)壓(ya)、功(gong)率因數(shu)、電(dian)(dian)(dian)流(liu)諧(xie)波、電(dian)(dian)(dian)壓(ya)諧(xie)波等(deng)。此外，多(duo)功(gong)能(neng)(neng)電(dian)(dian)(dian)力儀表還具有數(shu)據存儲、通(tong)信接口、報(bao)警(jing)功(gong)能(neng)(neng)等(deng)附(fu)加功(gong)能(neng)(neng)，可以更好地滿足(zu)不同用途和(he)應用場(chang)合的需求。

（3）應用區別

電(dian)度表通(tong)常應(ying)用(yong)(yong)于(yu)家庭和小(xiao)型商業(ye)用(yong)(yong)電(dian)量的(de)計量，例如住宅、商鋪等(deng)。而(er)多(duo)功能(neng)電(dian)力儀表則(ze)主要應(ying)用(yong)(yong)于(yu)工業(ye)生產線、電(dian)力系(xi)統等(deng)大型用(yong)(yong)電(dian)場合，其(qi)豐富的(de)電(dian)參數信(xin)息可以幫助用(yong)(yong)戶監測(ce)設備運行(xing)狀(zhuang)態、優化能(neng)源管理，提高用(yong)(yong)電(dian)效率。

二、多功能電力儀表能當電度表嗎

多功(gong)(gong)能(neng)電力(li)儀表(biao)(biao)集(ji)成了電壓(ya)表(biao)(biao)、電流表(biao)(biao)、功(gong)(gong)率因數表(biao)(biao)、功(gong)(gong)率表(biao)(biao)、頻率表(biao)(biao)、電度表(biao)(biao)的(de)功(gong)(gong)能(neng)，可以在一個(ge)顯示(shi)界(jie)面上滾動顯示(shi)上述量值，它也是可以起到電度表(biao)(biao)電能(neng)測量的(de)作用的(de)，不(bu)過一般來說，不(bu)建議用多功(gong)(gong)能(neng)電力(li)儀表(biao)(biao)當電度表(biao)(biao)用。

多功能電力儀表是(shi)(shi)測量(liang)(liang)表(biao)(biao)，測量(liang)(liang)表(biao)(biao)僅作為顯示、監控等使用，可(ke)(ke)清零可(ke)(ke)復位可(ke)(ke)改變比，且測量(liang)(liang)表(biao)(biao)計(ji)接(jie)入的(de)(de)CT、PT的(de)(de)精度(du)(du)級也都(dou)是(shi)(shi)測量(liang)(liang)級（一般是(shi)(shi)0.5級）；而電(dian)(dian)度(du)(du)表(biao)(biao)屬于計(ji)量(liang)(liang)表(biao)(biao)，不(bu)可(ke)(ke)清零不(bu)可(ke)(ke)復位不(bu)可(ke)(ke)改變比（用計(ji)量(liang)(liang)表(biao)(biao)廠家只提供給電(dian)(dian)力(li)公(gong)司的(de)(de)專業軟(ruan)件可(ke)(ke)以改，所(suo)以計(ji)量(liang)(liang)表(biao)(biao)需得到電(dian)(dian)力(li)公(gong)司的(de)(de)認(ren)證），接(jie)入的(de)(de)CT、PT的(de)(de)精度(du)(du)級也都(dou)是(shi)(shi)計(ji)量(liang)(liang)級（一般是(shi)(shi)0.2s或0.2級）。因此，不(bu)能(neng)把多(duo)功(gong)能(neng)電(dian)(dian)力(li)儀表(biao)(biao)當電(dian)(dian)度(du)(du)表(biao)(biao)用。
