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)電(dian)(dian)力儀(yi)表是一種具有可(ke)編(bian)程測(ce)(ce)量、顯示、數(shu)(shu)字通訊和電(dian)(dian)能(neng)(neng)脈沖變送(song)輸出(chu)等(deng)多功能(neng)(neng)智能(neng)(neng)儀(yi)表,具有完成電(dian)(dian)量測(ce)(ce)量、電(dian)(dian)能(neng)(neng)計量、數(shu)(shu)據顯示、采集(ji)及傳輸等(deng)功能(neng)(neng),廣泛應用于變電(dian)(dian)站自動(dong)化(hua)、配電(dian)(dian)自動(dong)化(hua)、智能(neng)(neng)建筑、企業內部的電(dian)(dian)能(neng)(neng)測(ce)(ce)量、管理、考(kao)核等(deng)。
2、什么是電度表
電(dian)度表又叫電(dian)能表,簡稱電(dian)表,是測量(liang)電(dian)能的儀(yi)表,廣(guang)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)度表(biao)是一種傳統的(de)電(dian)(dian)(dian)能(neng)測(ce)量(liang)儀(yi)表(biao),通(tong)常(chang)采用鐵芯電(dian)(dian)(dian)流(liu)互感(gan)器和電(dian)(dian)(dian)磁式電(dian)(dian)(dian)壓表(biao)實現(xian)測(ce)量(liang)。電(dian)(dian)(dian)度表(biao)通(tong)過對(dui)電(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)壓的(de)積分來計算(suan)電(dian)(dian)(dian)能(neng)的(de)消耗量(liang),因此它的(de)測(ce)量(liang)精度會(hui)受(shou)到(dao)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流(liu)波形的(de)影(ying)響(xiang)。多功能(neng)電(dian)(dian)(dian)力儀(yi)表(biao)則采用數字(zi)化技術實現(xian)電(dian)(dian)(dian)能(neng)測(ce)量(liang),其原理是通(tong)過對(dui)電(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)壓進行(xing)采樣和數字(zi)處理,并對(dui)測(ce)量(liang)結果進行(xing)校(xiao)正和計算(suan),可以實現(xian)高精度的(de)電(dian)(dian)(dian)能(neng)測(ce)量(liang)。
(2)功能區別
電(dian)(dian)(dian)(dian)(dian)度(du)表通常只能(neng)測量(liang)電(dian)(dian)(dian)(dian)(dian)能(neng)的消耗(hao)量(liang),不能(neng)提(ti)供(gong)其(qi)他相關的電(dian)(dian)(dian)(dian)(dian)參數(shu)(shu),例如(ru)功(gong)率因(yin)數(shu)(shu)、電(dian)(dian)(dian)(dian)(dian)流諧(xie)波(bo)等信息。而多(duo)功(gong)能(neng)電(dian)(dian)(dian)(dian)(dian)力儀(yi)表不僅(jin)可以(yi)測量(liang)電(dian)(dian)(dian)(dian)(dian)能(neng)的消耗(hao)量(liang),還(huan)可以(yi)提(ti)供(gong)豐富的電(dian)(dian)(dian)(dian)(dian)參數(shu)(shu)信息,例如(ru)電(dian)(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)(dian)壓(ya)、功(gong)率因(yin)數(shu)(shu)、電(dian)(dian)(dian)(dian)(dian)流諧(xie)波(bo)、電(dian)(dian)(dian)(dian)(dian)壓(ya)諧(xie)波(bo)等。此外(wai),多(duo)功(gong)能(neng)電(dian)(dian)(dian)(dian)(dian)力儀(yi)表還(huan)具有(you)數(shu)(shu)據存儲、通信接(jie)口、報(bao)警功(gong)能(neng)等附加(jia)功(gong)能(neng),可以(yi)更好地滿足不同用(yong)途(tu)和應用(yong)場合的需(xu)求。
(3)應用區別
電(dian)(dian)度表通(tong)常(chang)應(ying)用于(yu)家(jia)庭和(he)小型商業用電(dian)(dian)量的(de)(de)計量,例如住(zhu)宅、商鋪等。而多功能電(dian)(dian)力(li)儀表則(ze)主(zhu)要應(ying)用于(yu)工業生產線、電(dian)(dian)力(li)系(xi)統等大型用電(dian)(dian)場合,其豐(feng)富的(de)(de)電(dian)(dian)參數信(xin)息可以(yi)幫助用戶監測設備(bei)運行狀態、優化能源管理,提高(gao)用電(dian)(dian)效率。
二、多功能電力儀表能當電度表嗎
多功能電(dian)(dian)(dian)(dian)力儀(yi)(yi)表(biao)(biao)(biao)集成了(le)電(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)(biao)、電(dian)(dian)(dian)(dian)流表(biao)(biao)(biao)、功率(lv)(lv)因數(shu)表(biao)(biao)(biao)、功率(lv)(lv)表(biao)(biao)(biao)、頻率(lv)(lv)表(biao)(biao)(biao)、電(dian)(dian)(dian)(dian)度表(biao)(biao)(biao)的(de)功能,可(ke)以(yi)在一(yi)個顯示界面上(shang)滾動顯示上(shang)述量值,它也(ye)是可(ke)以(yi)起到電(dian)(dian)(dian)(dian)度表(biao)(biao)(biao)電(dian)(dian)(dian)(dian)能測(ce)量的(de)作用(yong)的(de),不(bu)過一(yi)般來說,不(bu)建議用(yong)多功能電(dian)(dian)(dian)(dian)力儀(yi)(yi)表(biao)(biao)(biao)當電(dian)(dian)(dian)(dian)度表(biao)(biao)(biao)用(yong)。
多功能電力儀表是(shi)(shi)測量(liang)(liang)(liang)表(biao)(biao),測量(liang)(liang)(liang)表(biao)(biao)僅作為顯示、監控等(deng)使用(yong),可(ke)(ke)(ke)(ke)清零可(ke)(ke)(ke)(ke)復(fu)位可(ke)(ke)(ke)(ke)改變比,且測量(liang)(liang)(liang)表(biao)(biao)計(ji)接(jie)(jie)入(ru)的(de)CT、PT的(de)精度級(ji)(ji)也都是(shi)(shi)測量(liang)(liang)(liang)級(ji)(ji)(一般是(shi)(shi)0.5級(ji)(ji));而電(dian)度表(biao)(biao)屬于計(ji)量(liang)(liang)(liang)表(biao)(biao),不(bu)可(ke)(ke)(ke)(ke)清零不(bu)可(ke)(ke)(ke)(ke)復(fu)位不(bu)可(ke)(ke)(ke)(ke)改變比(用(yong)計(ji)量(liang)(liang)(liang)表(biao)(biao)廠家只(zhi)提供(gong)給電(dian)力(li)公司(si)的(de)專業軟件可(ke)(ke)(ke)(ke)以改,所(suo)以計(ji)量(liang)(liang)(liang)表(biao)(biao)需得到電(dian)力(li)公司(si)的(de)認證),接(jie)(jie)入(ru)的(de)CT、PT的(de)精度級(ji)(ji)也都是(shi)(shi)計(ji)量(liang)(liang)(liang)級(ji)(ji)(一般是(shi)(shi)0.2s或0.2級(ji)(ji))。因此,不(bu)能把多(duo)功能電(dian)力(li)儀表(biao)(biao)當電(dian)度表(biao)(biao)用(yong)。
