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)電(dian)(dian)力儀表是一種(zhong)具有可編(bian)程測(ce)量(liang)、顯示、數(shu)字(zi)通訊和電(dian)(dian)能(neng)(neng)(neng)脈沖變送輸出等多功能(neng)(neng)(neng)智(zhi)能(neng)(neng)(neng)儀表，具有完(wan)成電(dian)(dian)量(liang)測(ce)量(liang)、電(dian)(dian)能(neng)(neng)(neng)計量(liang)、數(shu)據(ju)顯示、采集及傳輸等功能(neng)(neng)(neng)，廣泛應用于變電(dian)(dian)站(zhan)自動化、配電(dian)(dian)自動化、智(zhi)能(neng)(neng)(neng)建筑(zhu)、企業內部(bu)的電(dian)(dian)能(neng)(neng)(neng)測(ce)量(liang)、管理、考核等。

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)，是測量電(dian)能(neng)的儀表(biao)，廣泛(fan)應用(yong)于家(jia)庭用(yong)電(dian)、商業(ye)用(yong)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

電度(du)表(biao)是一種(zhong)傳統的(de)電能(neng)測量(liang)儀表(biao)，通常采(cai)(cai)用(yong)鐵(tie)芯(xin)電流(liu)(liu)互感(gan)器和(he)(he)電磁式電壓(ya)表(biao)實現測量(liang)。電度(du)表(biao)通過對(dui)電流(liu)(liu)和(he)(he)電壓(ya)的(de)積(ji)分來計算電能(neng)的(de)消(xiao)耗量(liang)，因此它的(de)測量(liang)精度(du)會(hui)受(shou)到(dao)電壓(ya)和(he)(he)電流(liu)(liu)波形(xing)的(de)影響(xiang)。多功能(neng)電力儀表(biao)則(ze)采(cai)(cai)用(yong)數(shu)字化(hua)技術實現電能(neng)測量(liang)，其原(yuan)理是通過對(dui)電流(liu)(liu)和(he)(he)電壓(ya)進(jin)行采(cai)(cai)樣和(he)(he)數(shu)字處理，并對(dui)測量(liang)結果進(jin)行校正和(he)(he)計算，可以實現高精度(du)的(de)電能(neng)測量(liang)。

（2）功能區別

電(dian)(dian)(dian)度表通常只能(neng)測(ce)量(liang)電(dian)(dian)(dian)能(neng)的消耗(hao)量(liang)，不能(neng)提供其他相關(guan)的電(dian)(dian)(dian)參(can)數，例(li)(li)如功率(lv)因數、電(dian)(dian)(dian)流(liu)諧波等(deng)信息。而多功能(neng)電(dian)(dian)(dian)力儀表不僅可(ke)以(yi)測(ce)量(liang)電(dian)(dian)(dian)能(neng)的消耗(hao)量(liang)，還(huan)(huan)可(ke)以(yi)提供豐富的電(dian)(dian)(dian)參(can)數信息，例(li)(li)如電(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)壓、功率(lv)因數、電(dian)(dian)(dian)流(liu)諧波、電(dian)(dian)(dian)壓諧波等(deng)。此外，多功能(neng)電(dian)(dian)(dian)力儀表還(huan)(huan)具有數據存儲、通信接(jie)口、報警功能(neng)等(deng)附加功能(neng)，可(ke)以(yi)更好地滿足(zu)不同用途和應用場合(he)的需求。

（3）應用區別

電(dian)(dian)(dian)(dian)(dian)度表通常應用于家庭(ting)和小型(xing)(xing)商業用電(dian)(dian)(dian)(dian)(dian)量的(de)(de)計量，例如住宅、商鋪等(deng)。而多(duo)功能電(dian)(dian)(dian)(dian)(dian)力儀表則主要(yao)應用于工業生(sheng)產線、電(dian)(dian)(dian)(dian)(dian)力系(xi)統等(deng)大型(xing)(xing)用電(dian)(dian)(dian)(dian)(dian)場(chang)合，其豐(feng)富的(de)(de)電(dian)(dian)(dian)(dian)(dian)參數信息可(ke)以幫(bang)助(zhu)用戶監(jian)測(ce)設備(bei)運行狀(zhuang)態、優化(hua)能源管理，提(ti)高用電(dian)(dian)(dian)(dian)(dian)效(xiao)率。

二、多功能電力儀表能當電度表嗎

多(duo)(duo)功(gong)(gong)(gong)能(neng)電(dian)(dian)(dian)(dian)力(li)儀表(biao)集成了電(dian)(dian)(dian)(dian)壓表(biao)、電(dian)(dian)(dian)(dian)流表(biao)、功(gong)(gong)(gong)率(lv)因數表(biao)、功(gong)(gong)(gong)率(lv)表(biao)、頻率(lv)表(biao)、電(dian)(dian)(dian)(dian)度表(biao)的(de)(de)功(gong)(gong)(gong)能(neng)，可(ke)以(yi)在(zai)一(yi)個顯示(shi)界面上滾動顯示(shi)上述量(liang)值，它也是(shi)可(ke)以(yi)起到電(dian)(dian)(dian)(dian)度表(biao)電(dian)(dian)(dian)(dian)能(neng)測量(liang)的(de)(de)作(zuo)用(yong)(yong)(yong)的(de)(de)，不過(guo)一(yi)般來說，不建議用(yong)(yong)(yong)多(duo)(duo)功(gong)(gong)(gong)能(neng)電(dian)(dian)(dian)(dian)力(li)儀表(biao)當電(dian)(dian)(dian)(dian)度表(biao)用(yong)(yong)(yong)。

多功能電力儀表是(shi)測量(liang)表(biao)(biao)，測量(liang)表(biao)(biao)僅作為顯(xian)示、監控(kong)等使用，可(ke)清零可(ke)復位(wei)可(ke)改(gai)(gai)變比(bi)，且測量(liang)表(biao)(biao)計接入的(de)(de)CT、PT的(de)(de)精度(du)級(ji)也都是(shi)測量(liang)級(ji)（一般(ban)是(shi)0.5級(ji)）；而電度(du)表(biao)(biao)屬(shu)于計量(liang)表(biao)(biao)，不(bu)(bu)可(ke)清零不(bu)(bu)可(ke)復位(wei)不(bu)(bu)可(ke)改(gai)(gai)變比(bi)（用計量(liang)表(biao)(biao)廠家(jia)只提(ti)供給電力公司的(de)(de)專業軟(ruan)件(jian)可(ke)以改(gai)(gai)，所(suo)以計量(liang)表(biao)(biao)需得到電力公司的(de)(de)認證），接入的(de)(de)CT、PT的(de)(de)精度(du)級(ji)也都是(shi)計量(liang)級(ji)（一般(ban)是(shi)0.2s或0.2級(ji)）。因此，不(bu)(bu)能把(ba)多功能電力儀表(biao)(biao)當電度(du)表(biao)(biao)用。
