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)能電(dian)力(li)儀(yi)表(biao)是一種具(ju)有可編程測(ce)量、顯(xian)(xian)示(shi)、數字(zi)通訊和電(dian)能脈(mo)沖變送輸出等(deng)多功(gong)能智能儀(yi)表(biao),具(ju)有完成(cheng)電(dian)量測(ce)量、電(dian)能計量、數據顯(xian)(xian)示(shi)、采集及傳輸等(deng)功(gong)能,廣(guang)泛(fan)應用于變電(dian)站自(zi)動化(hua)、配電(dian)自(zi)動化(hua)、智能建筑、企業內(nei)部的電(dian)能測(ce)量、管理、考核等(deng)。
2、什么是電度表
電(dian)(dian)度表又叫(jiao)電(dian)(dian)能表,簡稱電(dian)(dian)表,是測量電(dian)(dian)能的儀表,廣泛應(ying)用(yong)于家庭用(yong)電(dian)(dian)、商業(ye)用(yong)電(dian)(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)度(du)表(biao)(biao)是一(yi)種傳統(tong)的(de)電(dian)(dian)能(neng)測(ce)量(liang)(liang)(liang)儀表(biao)(biao),通常采(cai)用鐵芯電(dian)(dian)流(liu)互感器和電(dian)(dian)磁式電(dian)(dian)壓表(biao)(biao)實現(xian)測(ce)量(liang)(liang)(liang)。電(dian)(dian)度(du)表(biao)(biao)通過(guo)對電(dian)(dian)流(liu)和電(dian)(dian)壓的(de)積(ji)分來計(ji)算電(dian)(dian)能(neng)的(de)消耗量(liang)(liang)(liang),因(yin)此它(ta)的(de)測(ce)量(liang)(liang)(liang)精(jing)度(du)會受到電(dian)(dian)壓和電(dian)(dian)流(liu)波(bo)形的(de)影響。多功能(neng)電(dian)(dian)力儀表(biao)(biao)則采(cai)用數字(zi)化技術(shu)實現(xian)電(dian)(dian)能(neng)測(ce)量(liang)(liang)(liang),其原(yuan)理是通過(guo)對電(dian)(dian)流(liu)和電(dian)(dian)壓進(jin)行采(cai)樣和數字(zi)處(chu)理,并對測(ce)量(liang)(liang)(liang)結果(guo)進(jin)行校正和計(ji)算,可以實現(xian)高精(jing)度(du)的(de)電(dian)(dian)能(neng)測(ce)量(liang)(liang)(liang)。
(2)功能區別
電(dian)(dian)(dian)(dian)度表通常只能測量電(dian)(dian)(dian)(dian)能的(de)消耗量,不能提供(gong)其他相關(guan)的(de)電(dian)(dian)(dian)(dian)參數(shu)(shu)(shu),例如(ru)功(gong)率因(yin)數(shu)(shu)(shu)、電(dian)(dian)(dian)(dian)流(liu)諧波等信(xin)息。而多(duo)功(gong)能電(dian)(dian)(dian)(dian)力儀(yi)表不僅可以測量電(dian)(dian)(dian)(dian)能的(de)消耗量,還可以提供(gong)豐富的(de)電(dian)(dian)(dian)(dian)參數(shu)(shu)(shu)信(xin)息,例如(ru)電(dian)(dian)(dian)(dian)流(liu)、電(dian)(dian)(dian)(dian)壓、功(gong)率因(yin)數(shu)(shu)(shu)、電(dian)(dian)(dian)(dian)流(liu)諧波、電(dian)(dian)(dian)(dian)壓諧波等。此外,多(duo)功(gong)能電(dian)(dian)(dian)(dian)力儀(yi)表還具有數(shu)(shu)(shu)據(ju)存儲、通信(xin)接口、報(bao)警功(gong)能等附加功(gong)能,可以更(geng)好地滿足不同用途和應用場合(he)的(de)需(xu)求。
(3)應用區別
電(dian)度表(biao)通常應用(yong)(yong)(yong)于家庭和小型(xing)商(shang)業(ye)用(yong)(yong)(yong)電(dian)量的計(ji)量,例(li)如住宅(zhai)、商(shang)鋪等。而多(duo)功能電(dian)力儀表(biao)則主要應用(yong)(yong)(yong)于工(gong)業(ye)生產線(xian)、電(dian)力系統等大型(xing)用(yong)(yong)(yong)電(dian)場(chang)合,其豐富的電(dian)參數(shu)信息可以(yi)幫助(zhu)用(yong)(yong)(yong)戶監測設(she)備(bei)運行狀態(tai)、優化能源管理,提高用(yong)(yong)(yong)電(dian)效(xiao)率(lv)。
二、多功能電力儀表能當電度表嗎
多(duo)功(gong)能(neng)電力儀(yi)表(biao)(biao)集成了(le)電壓表(biao)(biao)、電流表(biao)(biao)、功(gong)率因數(shu)表(biao)(biao)、功(gong)率表(biao)(biao)、頻率表(biao)(biao)、電度(du)表(biao)(biao)的(de)功(gong)能(neng),可以(yi)在一個(ge)顯示界(jie)面上滾動顯示上述量(liang)值,它也(ye)是可以(yi)起到電度(du)表(biao)(biao)電能(neng)測(ce)量(liang)的(de)作用(yong)的(de),不(bu)過一般(ban)來說(shuo),不(bu)建議(yi)用(yong)多(duo)功(gong)能(neng)電力儀(yi)表(biao)(biao)當電度(du)表(biao)(biao)用(yong)。
多功能電力儀表是(shi)(shi)測量(liang)(liang)表(biao),測量(liang)(liang)表(biao)僅(jin)作為(wei)顯示、監控等使用(yong),可(ke)清(qing)零可(ke)復(fu)(fu)位可(ke)改(gai)變(bian)比(bi),且(qie)測量(liang)(liang)表(biao)計(ji)(ji)接入(ru)(ru)的(de)(de)CT、PT的(de)(de)精度級(ji)(ji)也都是(shi)(shi)測量(liang)(liang)級(ji)(ji)(一般是(shi)(shi)0.5級(ji)(ji));而電(dian)度表(biao)屬于計(ji)(ji)量(liang)(liang)表(biao),不(bu)可(ke)清(qing)零不(bu)可(ke)復(fu)(fu)位不(bu)可(ke)改(gai)變(bian)比(bi)(用(yong)計(ji)(ji)量(liang)(liang)表(biao)廠家只提供給電(dian)力公(gong)司的(de)(de)專(zhuan)業軟件可(ke)以(yi)改(gai),所以(yi)計(ji)(ji)量(liang)(liang)表(biao)需得(de)到電(dian)力公(gong)司的(de)(de)認證),接入(ru)(ru)的(de)(de)CT、PT的(de)(de)精度級(ji)(ji)也都是(shi)(shi)計(ji)(ji)量(liang)(liang)級(ji)(ji)(一般是(shi)(shi)0.2s或0.2級(ji)(ji))。因此(ci),不(bu)能(neng)把多(duo)功能(neng)電(dian)力儀表(biao)當電(dian)度表(biao)用(yong)。
