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)電力(li)儀表是一種具有可編程(cheng)測量、顯示、數字(zi)通訊和電能(neng)脈(mo)沖變送輸(shu)出等多(duo)功能(neng)智能(neng)儀表,具有完成(cheng)電量測量、電能(neng)計量、數據顯示、采(cai)集及傳輸(shu)等功能(neng),廣泛應用于變電站(zhan)自動(dong)化、配電自動(dong)化、智能(neng)建筑、企業內部的電能(neng)測量、管理、考核等。
2、什么是電度表
電(dian)度表(biao)(biao)又(you)叫電(dian)能(neng)表(biao)(biao),簡稱電(dian)表(biao)(biao),是測量(liang)電(dian)能(neng)的儀(yi)表(biao)(biao),廣泛應用(yong)于家庭用(yong)電(dian)、商業用(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(dian)(dian)(dian)(dian)度表(biao)是(shi)一種(zhong)傳(chuan)統(tong)的(de)電(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang)儀表(biao),通(tong)常(chang)采(cai)用(yong)鐵芯電(dian)(dian)(dian)(dian)流(liu)互感器(qi)和(he)(he)電(dian)(dian)(dian)(dian)磁(ci)式電(dian)(dian)(dian)(dian)壓表(biao)實(shi)現(xian)測(ce)(ce)(ce)量(liang)(liang)。電(dian)(dian)(dian)(dian)度表(biao)通(tong)過對(dui)(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)(he)電(dian)(dian)(dian)(dian)壓的(de)積(ji)分(fen)來(lai)計(ji)算電(dian)(dian)(dian)(dian)能(neng)(neng)的(de)消(xiao)耗量(liang)(liang),因此它的(de)測(ce)(ce)(ce)量(liang)(liang)精度會受到(dao)電(dian)(dian)(dian)(dian)壓和(he)(he)電(dian)(dian)(dian)(dian)流(liu)波形(xing)的(de)影(ying)響。多功能(neng)(neng)電(dian)(dian)(dian)(dian)力儀表(biao)則采(cai)用(yong)數(shu)(shu)字(zi)化(hua)技術(shu)實(shi)現(xian)電(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang),其(qi)原理(li)是(shi)通(tong)過對(dui)(dui)電(dian)(dian)(dian)(dian)流(liu)和(he)(he)電(dian)(dian)(dian)(dian)壓進行(xing)采(cai)樣和(he)(he)數(shu)(shu)字(zi)處理(li),并對(dui)(dui)測(ce)(ce)(ce)量(liang)(liang)結果進行(xing)校正和(he)(he)計(ji)算,可以實(shi)現(xian)高精度的(de)電(dian)(dian)(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang)。
(2)功能區別
電(dian)(dian)度表通(tong)常只能測量(liang)電(dian)(dian)能的(de)(de)消耗量(liang),不能提(ti)供(gong)其他相關的(de)(de)電(dian)(dian)參數(shu),例如功(gong)率因數(shu)、電(dian)(dian)流(liu)諧波等(deng)信息。而多(duo)功(gong)能電(dian)(dian)力(li)儀表不僅(jin)可以測量(liang)電(dian)(dian)能的(de)(de)消耗量(liang),還(huan)可以提(ti)供(gong)豐富的(de)(de)電(dian)(dian)參數(shu)信息,例如電(dian)(dian)流(liu)、電(dian)(dian)壓、功(gong)率因數(shu)、電(dian)(dian)流(liu)諧波、電(dian)(dian)壓諧波等(deng)。此外,多(duo)功(gong)能電(dian)(dian)力(li)儀表還(huan)具(ju)有數(shu)據(ju)存(cun)儲、通(tong)信接口、報(bao)警功(gong)能等(deng)附加功(gong)能,可以更好地滿足不同用途和應用場合的(de)(de)需(xu)求。
(3)應用區別
電(dian)度表通常(chang)應用(yong)(yong)于(yu)(yu)家庭和小型(xing)商(shang)業用(yong)(yong)電(dian)量的計量,例如住宅、商(shang)鋪等。而(er)多功能(neng)電(dian)力儀表則主要應用(yong)(yong)于(yu)(yu)工業生(sheng)產線、電(dian)力系統等大型(xing)用(yong)(yong)電(dian)場合(he),其豐(feng)富的電(dian)參數(shu)信息可以幫助(zhu)用(yong)(yong)戶監測設備運行狀態、優化能(neng)源管理,提高(gao)用(yong)(yong)電(dian)效(xiao)率。
二、多功能電力儀表能當電度表嗎
多(duo)(duo)功(gong)(gong)能(neng)電(dian)(dian)力儀(yi)表(biao)集成了電(dian)(dian)壓表(biao)、電(dian)(dian)流表(biao)、功(gong)(gong)率因(yin)數表(biao)、功(gong)(gong)率表(biao)、頻(pin)率表(biao)、電(dian)(dian)度(du)表(biao)的功(gong)(gong)能(neng),可以(yi)在一個顯(xian)示(shi)界面上滾(gun)動(dong)顯(xian)示(shi)上述量值,它也是可以(yi)起到電(dian)(dian)度(du)表(biao)電(dian)(dian)能(neng)測量的作(zuo)用(yong)的,不過(guo)一般(ban)來說,不建(jian)議用(yong)多(duo)(duo)功(gong)(gong)能(neng)電(dian)(dian)力儀(yi)表(biao)當電(dian)(dian)度(du)表(biao)用(yong)。
多功能電力儀表是測(ce)量(liang)表,測(ce)量(liang)表僅作為顯示、監控等使(shi)用(yong),可清(qing)零可復(fu)位可改(gai)變比(bi),且(qie)測(ce)量(liang)表計接(jie)入的(de)(de)(de)CT、PT的(de)(de)(de)精度(du)級(ji)也都(dou)是測(ce)量(liang)級(ji)(一(yi)般是0.5級(ji));而電(dian)(dian)度(du)表屬(shu)于(yu)計量(liang)表,不(bu)可清(qing)零不(bu)可復(fu)位不(bu)可改(gai)變比(bi)(用(yong)計量(liang)表廠家只提供給電(dian)(dian)力(li)(li)公(gong)司(si)的(de)(de)(de)專業(ye)軟件可以改(gai),所以計量(liang)表需得到電(dian)(dian)力(li)(li)公(gong)司(si)的(de)(de)(de)認證),接(jie)入的(de)(de)(de)CT、PT的(de)(de)(de)精度(du)級(ji)也都(dou)是計量(liang)級(ji)(一(yi)般是0.2s或(huo)0.2級(ji))。因(yin)此,不(bu)能(neng)把多功能(neng)電(dian)(dian)力(li)(li)儀表當電(dian)(dian)度(du)表用(yong)。
