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)電(dian)(dian)力(li)儀表是一(yi)種具有(you)可編(bian)程測(ce)量(liang)、顯示、數字通訊和(he)電(dian)(dian)能(neng)脈(mo)沖變(bian)送輸出等(deng)多功能(neng)智能(neng)儀表,具有(you)完成電(dian)(dian)量(liang)測(ce)量(liang)、電(dian)(dian)能(neng)計量(liang)、數據顯示、采集及傳輸等(deng)功能(neng),廣泛應(ying)用于變(bian)電(dian)(dian)站自動(dong)化、配(pei)電(dian)(dian)自動(dong)化、智能(neng)建(jian)筑、企(qi)業(ye)內(nei)部的(de)電(dian)(dian)能(neng)測(ce)量(liang)、管理、考(kao)核(he)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)用于家庭用電(dian)(dian)、商業用電(dian)(dian)等方(fang)面。
3、多功能電力儀表和電度表的區別
(1)原理區別
電(dian)(dian)度表(biao)(biao)是一(yi)種傳統的(de)電(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang)儀表(biao)(biao),通常采用鐵芯電(dian)(dian)流(liu)(liu)互感器和(he)電(dian)(dian)磁式電(dian)(dian)壓(ya)表(biao)(biao)實現(xian)測(ce)(ce)(ce)量(liang)(liang)。電(dian)(dian)度表(biao)(biao)通過(guo)對電(dian)(dian)流(liu)(liu)和(he)電(dian)(dian)壓(ya)的(de)積分(fen)來計算電(dian)(dian)能(neng)(neng)的(de)消耗量(liang)(liang),因此它的(de)測(ce)(ce)(ce)量(liang)(liang)精(jing)度會受到電(dian)(dian)壓(ya)和(he)電(dian)(dian)流(liu)(liu)波(bo)形的(de)影響。多功能(neng)(neng)電(dian)(dian)力儀表(biao)(biao)則采用數字化技術(shu)實現(xian)電(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang),其(qi)原理(li)是通過(guo)對電(dian)(dian)流(liu)(liu)和(he)電(dian)(dian)壓(ya)進行采樣和(he)數字處(chu)理(li),并(bing)對測(ce)(ce)(ce)量(liang)(liang)結(jie)果進行校正和(he)計算,可以實現(xian)高(gao)精(jing)度的(de)電(dian)(dian)能(neng)(neng)測(ce)(ce)(ce)量(liang)(liang)。
(2)功能區別
電(dian)(dian)度(du)表通常只能(neng)測(ce)量電(dian)(dian)能(neng)的消耗量,不能(neng)提(ti)供其他相關的電(dian)(dian)參數(shu)(shu),例(li)如(ru)功(gong)率因數(shu)(shu)、電(dian)(dian)流諧波等信息。而多功(gong)能(neng)電(dian)(dian)力儀表不僅可以測(ce)量電(dian)(dian)能(neng)的消耗量,還可以提(ti)供豐富的電(dian)(dian)參數(shu)(shu)信息,例(li)如(ru)電(dian)(dian)流、電(dian)(dian)壓、功(gong)率因數(shu)(shu)、電(dian)(dian)流諧波、電(dian)(dian)壓諧波等。此外,多功(gong)能(neng)電(dian)(dian)力儀表還具有數(shu)(shu)據存儲、通信接口(kou)、報警功(gong)能(neng)等附(fu)加(jia)功(gong)能(neng),可以更(geng)好地滿足(zu)不同用(yong)途和應用(yong)場合的需求。
(3)應用區別
電(dian)(dian)(dian)(dian)(dian)度表通常應用(yong)于家庭和(he)小型(xing)商(shang)業用(yong)電(dian)(dian)(dian)(dian)(dian)量(liang)的(de)計量(liang),例如住宅、商(shang)鋪等(deng)。而多(duo)功能電(dian)(dian)(dian)(dian)(dian)力(li)儀表則(ze)主要應用(yong)于工業生(sheng)產線、電(dian)(dian)(dian)(dian)(dian)力(li)系統等(deng)大(da)型(xing)用(yong)電(dian)(dian)(dian)(dian)(dian)場合,其豐富的(de)電(dian)(dian)(dian)(dian)(dian)參數(shu)信(xin)息可以幫助用(yong)戶監(jian)測設(she)備(bei)運行狀(zhuang)態、優化能源管理,提(ti)高用(yong)電(dian)(dian)(dian)(dian)(dian)效率。
二、多功能電力儀表能當電度表嗎
多功(gong)能(neng)(neng)電力儀(yi)表(biao)(biao)集成(cheng)了電壓表(biao)(biao)、電流表(biao)(biao)、功(gong)率(lv)因數表(biao)(biao)、功(gong)率(lv)表(biao)(biao)、頻率(lv)表(biao)(biao)、電度表(biao)(biao)的功(gong)能(neng)(neng),可以(yi)在一個(ge)顯(xian)示界面上(shang)(shang)滾動(dong)顯(xian)示上(shang)(shang)述量值,它也是可以(yi)起到(dao)電度表(biao)(biao)電能(neng)(neng)測量的作用的,不(bu)過一般來說(shuo),不(bu)建議用多功(gong)能(neng)(neng)電力儀(yi)表(biao)(biao)當(dang)電度表(biao)(biao)用。
多功能電力儀表是(shi)測量(liang)(liang)表(biao),測量(liang)(liang)表(biao)僅作為顯示(shi)、監控(kong)等使(shi)用(yong),可清零可復位可改(gai)(gai)變(bian)(bian)比,且測量(liang)(liang)表(biao)計(ji)接入的CT、PT的精度(du)級(ji)也(ye)都(dou)(dou)是(shi)測量(liang)(liang)級(ji)(一(yi)般是(shi)0.5級(ji));而(er)電(dian)度(du)表(biao)屬于計(ji)量(liang)(liang)表(biao),不可清零不可復位不可改(gai)(gai)變(bian)(bian)比(用(yong)計(ji)量(liang)(liang)表(biao)廠家只提(ti)供給電(dian)力(li)公(gong)司的專業(ye)軟件可以改(gai)(gai),所以計(ji)量(liang)(liang)表(biao)需得到電(dian)力(li)公(gong)司的認證),接入的CT、PT的精度(du)級(ji)也(ye)都(dou)(dou)是(shi)計(ji)量(liang)(liang)級(ji)(一(yi)般是(shi)0.2s或0.2級(ji))。因此,不能把多功能電(dian)力(li)儀表(biao)當電(dian)度(du)表(biao)用(yong)。
