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(gong)能(neng)電(dian)力儀表(biao)是一種具(ju)(ju)有可編程測量(liang)(liang)、顯示、數字通訊和(he)電(dian)能(neng)脈沖變(bian)送輸出等(deng)多功(gong)能(neng)智能(neng)儀表(biao)，具(ju)(ju)有完成電(dian)量(liang)(liang)測量(liang)(liang)、電(dian)能(neng)計量(liang)(liang)、數據顯示、采集及傳輸等(deng)功(gong)能(neng)，廣(guang)泛應(ying)用于變(bian)電(dian)站自(zi)動化、配電(dian)自(zi)動化、智能(neng)建(jian)筑、企業內部的(de)電(dian)能(neng)測量(liang)(liang)、管理、考核(he)等(deng)。

2、什么是電度表

電(dian)度表(biao)又叫電(dian)能(neng)表(biao)，簡稱電(dian)表(biao)，是測(ce)量電(dian)能(neng)的儀表(biao)，廣泛應用(yong)(yong)于家庭用(yong)(yong)電(dian)、商業(ye)用(yong)(yong)電(dian)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)度(du)表(biao)(biao)是一種傳統的(de)(de)(de)電(dian)(dian)(dian)(dian)能(neng)測(ce)量儀表(biao)(biao)，通(tong)常采(cai)(cai)用鐵(tie)芯電(dian)(dian)(dian)(dian)流(liu)互感器和(he)電(dian)(dian)(dian)(dian)磁式電(dian)(dian)(dian)(dian)壓表(biao)(biao)實(shi)(shi)現(xian)測(ce)量。電(dian)(dian)(dian)(dian)度(du)表(biao)(biao)通(tong)過(guo)對(dui)(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)壓的(de)(de)(de)積分來計算電(dian)(dian)(dian)(dian)能(neng)的(de)(de)(de)消耗量，因此它的(de)(de)(de)測(ce)量精度(du)會受到電(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)流(liu)波(bo)形的(de)(de)(de)影響。多功能(neng)電(dian)(dian)(dian)(dian)力儀表(biao)(biao)則采(cai)(cai)用數(shu)字化技術實(shi)(shi)現(xian)電(dian)(dian)(dian)(dian)能(neng)測(ce)量，其原理(li)是通(tong)過(guo)對(dui)(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)電(dian)(dian)(dian)(dian)壓進行采(cai)(cai)樣和(he)數(shu)字處(chu)理(li)，并對(dui)(dui)測(ce)量結果進行校(xiao)正和(he)計算，可以實(shi)(shi)現(xian)高精度(du)的(de)(de)(de)電(dian)(dian)(dian)(dian)能(neng)測(ce)量。

（2）功能區別

電(dian)(dian)度表(biao)(biao)通常(chang)只能(neng)測量電(dian)(dian)能(neng)的(de)消(xiao)耗量，不能(neng)提(ti)供其他相關(guan)的(de)電(dian)(dian)參數(shu)，例如功率(lv)因數(shu)、電(dian)(dian)流(liu)諧波(bo)等(deng)信(xin)(xin)息(xi)。而(er)多(duo)功能(neng)電(dian)(dian)力儀表(biao)(biao)不僅可(ke)以測量電(dian)(dian)能(neng)的(de)消(xiao)耗量，還(huan)(huan)可(ke)以提(ti)供豐富的(de)電(dian)(dian)參數(shu)信(xin)(xin)息(xi)，例如電(dian)(dian)流(liu)、電(dian)(dian)壓、功率(lv)因數(shu)、電(dian)(dian)流(liu)諧波(bo)、電(dian)(dian)壓諧波(bo)等(deng)。此外，多(duo)功能(neng)電(dian)(dian)力儀表(biao)(biao)還(huan)(huan)具(ju)有數(shu)據存儲、通信(xin)(xin)接口(kou)、報警功能(neng)等(deng)附加功能(neng)，可(ke)以更好地滿足不同用途和應用場(chang)合(he)的(de)需求。

（3）應用區別

電(dian)(dian)(dian)度表通常(chang)應(ying)用(yong)于家(jia)庭(ting)和小型商業用(yong)電(dian)(dian)(dian)量的計量，例如(ru)住宅(zhai)、商鋪(pu)等。而多功能(neng)電(dian)(dian)(dian)力儀(yi)表則主要(yao)應(ying)用(yong)于工業生產線、電(dian)(dian)(dian)力系統等大(da)型用(yong)電(dian)(dian)(dian)場(chang)合，其豐富的電(dian)(dian)(dian)參數信息可以幫助(zhu)用(yong)戶監測設備運行狀態、優化(hua)能(neng)源管理，提高用(yong)電(dian)(dian)(dian)效率(lv)。

二、多功能電力儀表能當電度表嗎

多功能電(dian)(dian)力儀表(biao)(biao)集成了電(dian)(dian)壓表(biao)(biao)、電(dian)(dian)流表(biao)(biao)、功率(lv)因數表(biao)(biao)、功率(lv)表(biao)(biao)、頻率(lv)表(biao)(biao)、電(dian)(dian)度(du)表(biao)(biao)的(de)功能，可(ke)以在一個顯示界面上(shang)滾動(dong)顯示上(shang)述量值，它也是可(ke)以起(qi)到(dao)電(dian)(dian)度(du)表(biao)(biao)電(dian)(dian)能測量的(de)作(zuo)用的(de)，不(bu)過(guo)一般來說(shuo)，不(bu)建議用多功能電(dian)(dian)力儀表(biao)(biao)當(dang)電(dian)(dian)度(du)表(biao)(biao)用。

多功能電力儀表是(shi)測(ce)(ce)(ce)量(liang)(liang)(liang)表，測(ce)(ce)(ce)量(liang)(liang)(liang)表僅(jin)作為顯示(shi)、監控等(deng)使用(yong)，可(ke)(ke)清零可(ke)(ke)復位(wei)可(ke)(ke)改(gai)變比，且測(ce)(ce)(ce)量(liang)(liang)(liang)表計接(jie)入的CT、PT的精度級(ji)也(ye)都(dou)(dou)是(shi)測(ce)(ce)(ce)量(liang)(liang)(liang)級(ji)（一般是(shi)0.5級(ji)）；而電(dian)度表屬(shu)于計量(liang)(liang)(liang)表，不(bu)(bu)可(ke)(ke)清零不(bu)(bu)可(ke)(ke)復位(wei)不(bu)(bu)可(ke)(ke)改(gai)變比（用(yong)計量(liang)(liang)(liang)表廠家只(zhi)提供(gong)給電(dian)力(li)公(gong)司(si)(si)的專業軟(ruan)件可(ke)(ke)以(yi)改(gai)，所以(yi)計量(liang)(liang)(liang)表需得到電(dian)力(li)公(gong)司(si)(si)的認證(zheng)），接(jie)入的CT、PT的精度級(ji)也(ye)都(dou)(dou)是(shi)計量(liang)(liang)(liang)級(ji)（一般是(shi)0.2s或(huo)0.2級(ji)）。因此，不(bu)(bu)能把多功能電(dian)力(li)儀表當(dang)電(dian)度表用(yong)。
