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(neng)(neng)電力(li)儀表是一種具有可(ke)編程測(ce)量、顯(xian)(xian)示、數字通訊和電能(neng)(neng)脈沖變送(song)輸出等多功(gong)能(neng)(neng)智(zhi)能(neng)(neng)儀表,具有完成電量測(ce)量、電能(neng)(neng)計量、數據顯(xian)(xian)示、采集及傳輸等功(gong)能(neng)(neng),廣泛(fan)應用于(yu)變電站(zhan)自(zi)(zi)動化(hua)、配(pei)電自(zi)(zi)動化(hua)、智(zhi)能(neng)(neng)建筑(zhu)、企(qi)業內(nei)部的電能(neng)(neng)測(ce)量、管(guan)理、考核等。
2、什么是電度表
電(dian)度表(biao)(biao)又叫電(dian)能表(biao)(biao),簡(jian)稱電(dian)表(biao)(biao),是測量電(dian)能的儀表(biao)(biao),廣泛(fan)應(ying)用于家庭用電(dian)、商(shang)業(ye)用電(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)(dian)度(du)表(biao)是一(yi)種傳統的(de)電(dian)(dian)(dian)(dian)(dian)能測量(liang)儀(yi)表(biao),通常采(cai)(cai)用鐵芯電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)互感器和(he)(he)(he)(he)電(dian)(dian)(dian)(dian)(dian)磁式(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)實(shi)現(xian)(xian)測量(liang)。電(dian)(dian)(dian)(dian)(dian)度(du)表(biao)通過對電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和(he)(he)(he)(he)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)積分來計算電(dian)(dian)(dian)(dian)(dian)能的(de)消耗量(liang),因此它的(de)測量(liang)精度(du)會(hui)受到電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)(he)(he)(he)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)波形的(de)影(ying)響。多功能電(dian)(dian)(dian)(dian)(dian)力(li)儀(yi)表(biao)則(ze)采(cai)(cai)用數字(zi)化(hua)技術實(shi)現(xian)(xian)電(dian)(dian)(dian)(dian)(dian)能測量(liang),其原理(li)(li)是通過對電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和(he)(he)(he)(he)電(dian)(dian)(dian)(dian)(dian)壓(ya)進行采(cai)(cai)樣和(he)(he)(he)(he)數字(zi)處理(li)(li),并(bing)對測量(liang)結果進行校正(zheng)和(he)(he)(he)(he)計算,可以實(shi)現(xian)(xian)高(gao)精度(du)的(de)電(dian)(dian)(dian)(dian)(dian)能測量(liang)。
(2)功能區別
電(dian)(dian)度表通常只能(neng)測(ce)量電(dian)(dian)能(neng)的(de)消(xiao)(xiao)耗(hao)量,不(bu)能(neng)提供(gong)其他相關的(de)電(dian)(dian)參(can)數(shu)(shu),例如(ru)功率(lv)因數(shu)(shu)、電(dian)(dian)流(liu)(liu)諧波等(deng)信息。而多(duo)(duo)功能(neng)電(dian)(dian)力儀(yi)(yi)表不(bu)僅(jin)可以(yi)(yi)測(ce)量電(dian)(dian)能(neng)的(de)消(xiao)(xiao)耗(hao)量,還可以(yi)(yi)提供(gong)豐富(fu)的(de)電(dian)(dian)參(can)數(shu)(shu)信息,例如(ru)電(dian)(dian)流(liu)(liu)、電(dian)(dian)壓、功率(lv)因數(shu)(shu)、電(dian)(dian)流(liu)(liu)諧波、電(dian)(dian)壓諧波等(deng)。此外,多(duo)(duo)功能(neng)電(dian)(dian)力儀(yi)(yi)表還具有數(shu)(shu)據存儲、通信接口(kou)、報警功能(neng)等(deng)附(fu)加功能(neng),可以(yi)(yi)更好地滿足(zu)不(bu)同用途和應用場(chang)合的(de)需(xu)求。
(3)應用區別
電(dian)度表通常應用(yong)(yong)于(yu)家庭和小型(xing)商業(ye)用(yong)(yong)電(dian)量的(de)計量,例(li)如(ru)住(zhu)宅、商鋪等(deng)。而多功能電(dian)力儀表則(ze)主要應用(yong)(yong)于(yu)工業(ye)生產(chan)線、電(dian)力系統等(deng)大型(xing)用(yong)(yong)電(dian)場合,其豐富的(de)電(dian)參數(shu)信息可以幫助用(yong)(yong)戶監(jian)測設備運行(xing)狀態、優化能源(yuan)管理(li),提高用(yong)(yong)電(dian)效率。
二、多功能電力儀表能當電度表嗎
多功(gong)能電(dian)力儀(yi)表(biao)集成了(le)電(dian)壓表(biao)、電(dian)流表(biao)、功(gong)率因數表(biao)、功(gong)率表(biao)、頻率表(biao)、電(dian)度(du)表(biao)的(de)功(gong)能,可以(yi)(yi)在一個(ge)顯(xian)示界面(mian)上滾動顯(xian)示上述量值(zhi),它也是可以(yi)(yi)起(qi)到電(dian)度(du)表(biao)電(dian)能測量的(de)作用的(de),不(bu)過(guo)一般來說,不(bu)建(jian)議(yi)用多功(gong)能電(dian)力儀(yi)表(biao)當(dang)電(dian)度(du)表(biao)用。
多功能電力儀表是(shi)(shi)測(ce)(ce)量(liang)(liang)(liang)表(biao),測(ce)(ce)量(liang)(liang)(liang)表(biao)僅作(zuo)為顯示(shi)、監控等使(shi)用,可(ke)(ke)(ke)(ke)清零(ling)可(ke)(ke)(ke)(ke)復位(wei)可(ke)(ke)(ke)(ke)改變(bian)(bian)比,且測(ce)(ce)量(liang)(liang)(liang)表(biao)計接(jie)入的CT、PT的精(jing)度(du)級(ji)也都是(shi)(shi)測(ce)(ce)量(liang)(liang)(liang)級(ji)(一般是(shi)(shi)0.5級(ji));而電度(du)表(biao)屬于計量(liang)(liang)(liang)表(biao),不可(ke)(ke)(ke)(ke)清零(ling)不可(ke)(ke)(ke)(ke)復位(wei)不可(ke)(ke)(ke)(ke)改變(bian)(bian)比(用計量(liang)(liang)(liang)表(biao)廠(chang)家只(zhi)提供(gong)給電力公司的專業軟件可(ke)(ke)(ke)(ke)以改,所以計量(liang)(liang)(liang)表(biao)需得(de)到(dao)電力公司的認(ren)證(zheng)),接(jie)入的CT、PT的精(jing)度(du)級(ji)也都是(shi)(shi)計量(liang)(liang)(liang)級(ji)(一般是(shi)(shi)0.2s或0.2級(ji))。因此,不能(neng)把多功能(neng)電力儀表(biao)當電度(du)表(biao)用。
