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)(gong)能(neng)電(dian)力儀表是(shi)一種具有(you)可編程測(ce)量(liang)、顯示、數字通訊和電(dian)能(neng)脈(mo)沖(chong)變送輸出(chu)等(deng)多功(gong)(gong)能(neng)智能(neng)儀表,具有(you)完成電(dian)量(liang)測(ce)量(liang)、電(dian)能(neng)計量(liang)、數據顯示、采集(ji)及(ji)傳輸等(deng)功(gong)(gong)能(neng),廣泛應用于變電(dian)站自動化、配電(dian)自動化、智能(neng)建筑、企業(ye)內部的電(dian)能(neng)測(ce)量(liang)、管理(li)、考(kao)核等(deng)。
2、什么是電度表
電(dian)度表(biao)又(you)叫電(dian)能(neng)表(biao),簡稱電(dian)表(biao),是測量電(dian)能(neng)的(de)儀表(biao),廣泛應用于家(jia)庭用電(dian)、商業用電(dian)等方(fang)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)(du)表(biao)是(shi)一種傳(chuan)統的(de)電(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)(liang)儀表(biao),通(tong)常采(cai)用(yong)鐵芯電(dian)(dian)(dian)(dian)流互感器和(he)(he)(he)電(dian)(dian)(dian)(dian)磁式電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)表(biao)實(shi)現測(ce)(ce)量(liang)(liang)(liang)。電(dian)(dian)(dian)(dian)度(du)(du)表(biao)通(tong)過對(dui)(dui)電(dian)(dian)(dian)(dian)流和(he)(he)(he)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)積分來計算電(dian)(dian)(dian)(dian)能(neng)的(de)消耗量(liang)(liang)(liang),因此它的(de)測(ce)(ce)量(liang)(liang)(liang)精(jing)度(du)(du)會受到電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和(he)(he)(he)電(dian)(dian)(dian)(dian)流波形的(de)影(ying)響(xiang)。多(duo)功能(neng)電(dian)(dian)(dian)(dian)力儀表(biao)則采(cai)用(yong)數字化技術實(shi)現電(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)(liang),其原理是(shi)通(tong)過對(dui)(dui)電(dian)(dian)(dian)(dian)流和(he)(he)(he)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)進行采(cai)樣(yang)和(he)(he)(he)數字處理,并對(dui)(dui)測(ce)(ce)量(liang)(liang)(liang)結果進行校正和(he)(he)(he)計算,可以實(shi)現高(gao)精(jing)度(du)(du)的(de)電(dian)(dian)(dian)(dian)能(neng)測(ce)(ce)量(liang)(liang)(liang)。
(2)功能區別
電(dian)(dian)度表通常只能(neng)測(ce)量(liang)(liang)電(dian)(dian)能(neng)的(de)消耗(hao)量(liang)(liang),不能(neng)提(ti)供其他相關的(de)電(dian)(dian)參數(shu)(shu),例如功(gong)率因數(shu)(shu)、電(dian)(dian)流諧波等(deng)信息(xi)。而多功(gong)能(neng)電(dian)(dian)力儀表不僅可(ke)以(yi)(yi)(yi)測(ce)量(liang)(liang)電(dian)(dian)能(neng)的(de)消耗(hao)量(liang)(liang),還可(ke)以(yi)(yi)(yi)提(ti)供豐富的(de)電(dian)(dian)參數(shu)(shu)信息(xi),例如電(dian)(dian)流、電(dian)(dian)壓(ya)、功(gong)率因數(shu)(shu)、電(dian)(dian)流諧波、電(dian)(dian)壓(ya)諧波等(deng)。此外(wai),多功(gong)能(neng)電(dian)(dian)力儀表還具有數(shu)(shu)據(ju)存儲、通信接(jie)口、報警(jing)功(gong)能(neng)等(deng)附加(jia)功(gong)能(neng),可(ke)以(yi)(yi)(yi)更好地滿足(zu)不同用途和應用場合的(de)需求。
(3)應用區別
電(dian)度表通(tong)常應(ying)用(yong)于家庭(ting)和小(xiao)型(xing)商業用(yong)電(dian)量的(de)(de)計量,例如住(zhu)宅、商鋪等(deng)。而多(duo)功能(neng)電(dian)力儀(yi)表則主(zhu)要(yao)應(ying)用(yong)于工業生(sheng)產線(xian)、電(dian)力系統等(deng)大型(xing)用(yong)電(dian)場合,其豐富的(de)(de)電(dian)參數(shu)信息(xi)可以(yi)幫助(zhu)用(yong)戶監測設(she)備運(yun)行狀態、優化能(neng)源管理,提高用(yong)電(dian)效(xiao)率。
二、多功能電力儀表能當電度表嗎
多功能(neng)(neng)電(dian)(dian)(dian)力儀表(biao)集成了電(dian)(dian)(dian)壓表(biao)、電(dian)(dian)(dian)流表(biao)、功率因數表(biao)、功率表(biao)、頻率表(biao)、電(dian)(dian)(dian)度表(biao)的(de)功能(neng)(neng),可(ke)以(yi)在一個(ge)顯(xian)示(shi)界面上(shang)滾(gun)動(dong)顯(xian)示(shi)上(shang)述量(liang)值(zhi),它也(ye)是可(ke)以(yi)起到電(dian)(dian)(dian)度表(biao)電(dian)(dian)(dian)能(neng)(neng)測量(liang)的(de)作用的(de),不過(guo)一般來說,不建議(yi)用多功能(neng)(neng)電(dian)(dian)(dian)力儀表(biao)當電(dian)(dian)(dian)度表(biao)用。
多功能電力儀表是測量(liang)表(biao)(biao)(biao),測量(liang)表(biao)(biao)(biao)僅作為顯示、監控等使用(yong)(yong),可(ke)(ke)清(qing)零可(ke)(ke)復(fu)位可(ke)(ke)改(gai)(gai)變比(bi),且(qie)測量(liang)表(biao)(biao)(biao)計接(jie)入(ru)的(de)CT、PT的(de)精度級(ji)(ji)也(ye)都(dou)是測量(liang)級(ji)(ji)(一般(ban)是0.5級(ji)(ji));而(er)電(dian)度表(biao)(biao)(biao)屬于(yu)計量(liang)表(biao)(biao)(biao),不可(ke)(ke)清(qing)零不可(ke)(ke)復(fu)位不可(ke)(ke)改(gai)(gai)變比(bi)(用(yong)(yong)計量(liang)表(biao)(biao)(biao)廠家只提(ti)供給電(dian)力公司的(de)專業軟(ruan)件可(ke)(ke)以改(gai)(gai),所以計量(liang)表(biao)(biao)(biao)需得(de)到(dao)電(dian)力公司的(de)認證),接(jie)入(ru)的(de)CT、PT的(de)精度級(ji)(ji)也(ye)都(dou)是計量(liang)級(ji)(ji)(一般(ban)是0.2s或0.2級(ji)(ji))。因(yin)此,不能把多功能電(dian)力儀表(biao)(biao)(biao)當電(dian)度表(biao)(biao)(biao)用(yong)(yong)。
