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(duo)功(gong)能電(dian)(dian)(dian)力儀表是一(yi)種具(ju)有可編程測(ce)量、顯示、數(shu)字通訊(xun)和電(dian)(dian)(dian)能脈(mo)沖(chong)變送(song)輸出等多(duo)功(gong)能智能儀表,具(ju)有完成電(dian)(dian)(dian)量測(ce)量、電(dian)(dian)(dian)能計量、數(shu)據顯示、采集及傳(chuan)輸等功(gong)能,廣(guang)泛(fan)應用于變電(dian)(dian)(dian)站自動(dong)化(hua)、配(pei)電(dian)(dian)(dian)自動(dong)化(hua)、智能建筑、企業內(nei)部的電(dian)(dian)(dian)能測(ce)量、管理(li)、考核等。
2、什么是電度表
電度表(biao)又叫電能表(biao),簡稱電表(biao),是測(ce)量電能的(de)儀表(biao),廣(guang)泛應(ying)用于家庭用電、商(shang)業用電等方面。
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)表是(shi)一(yi)種傳統的電(dian)(dian)能(neng)(neng)測(ce)(ce)量(liang)儀(yi)表,通(tong)常采用(yong)鐵(tie)芯電(dian)(dian)流(liu)互感器和(he)電(dian)(dian)磁式(shi)電(dian)(dian)壓(ya)表實現(xian)(xian)測(ce)(ce)量(liang)。電(dian)(dian)度(du)表通(tong)過(guo)對(dui)電(dian)(dian)流(liu)和(he)電(dian)(dian)壓(ya)的積(ji)分來計算電(dian)(dian)能(neng)(neng)的消耗量(liang),因此(ci)它的測(ce)(ce)量(liang)精(jing)度(du)會受(shou)到電(dian)(dian)壓(ya)和(he)電(dian)(dian)流(liu)波形的影響(xiang)。多功能(neng)(neng)電(dian)(dian)力儀(yi)表則采用(yong)數字化(hua)技術實現(xian)(xian)電(dian)(dian)能(neng)(neng)測(ce)(ce)量(liang),其原理(li)是(shi)通(tong)過(guo)對(dui)電(dian)(dian)流(liu)和(he)電(dian)(dian)壓(ya)進(jin)行(xing)采樣和(he)數字處理(li),并(bing)對(dui)測(ce)(ce)量(liang)結(jie)果進(jin)行(xing)校正和(he)計算,可以實現(xian)(xian)高精(jing)度(du)的電(dian)(dian)能(neng)(neng)測(ce)(ce)量(liang)。
(2)功能區別
電(dian)(dian)度表通常只能測量(liang)(liang)電(dian)(dian)能的(de)消耗量(liang)(liang),不能提供其他(ta)相關的(de)電(dian)(dian)參數(shu),例如功(gong)(gong)率因數(shu)、電(dian)(dian)流(liu)諧(xie)波(bo)(bo)等(deng)信(xin)(xin)息。而(er)多(duo)功(gong)(gong)能電(dian)(dian)力儀(yi)表不僅可以測量(liang)(liang)電(dian)(dian)能的(de)消耗量(liang)(liang),還(huan)可以提供豐富的(de)電(dian)(dian)參數(shu)信(xin)(xin)息,例如電(dian)(dian)流(liu)、電(dian)(dian)壓(ya)、功(gong)(gong)率因數(shu)、電(dian)(dian)流(liu)諧(xie)波(bo)(bo)、電(dian)(dian)壓(ya)諧(xie)波(bo)(bo)等(deng)。此外,多(duo)功(gong)(gong)能電(dian)(dian)力儀(yi)表還(huan)具有(you)數(shu)據存儲(chu)、通信(xin)(xin)接口、報警功(gong)(gong)能等(deng)附加(jia)功(gong)(gong)能,可以更好地(di)滿(man)足不同用途(tu)和應用場合的(de)需求。
(3)應用區別
電(dian)度表(biao)通(tong)常應(ying)用(yong)于(yu)(yu)家庭(ting)和(he)小型商(shang)業用(yong)電(dian)量的計量,例如住宅、商(shang)鋪等(deng)。而多(duo)功能電(dian)力儀表(biao)則主要應(ying)用(yong)于(yu)(yu)工業生產線(xian)、電(dian)力系統等(deng)大型用(yong)電(dian)場合,其豐富的電(dian)參數信息(xi)可以幫(bang)助用(yong)戶監(jian)測設備運行狀(zhuang)態、優化能源(yuan)管理,提高(gao)用(yong)電(dian)效率(lv)。
二、多功能電力儀表能當電度表嗎
多功能(neng)電(dian)(dian)(dian)力(li)儀表(biao)集成了電(dian)(dian)(dian)壓表(biao)、電(dian)(dian)(dian)流表(biao)、功率(lv)(lv)因數表(biao)、功率(lv)(lv)表(biao)、頻率(lv)(lv)表(biao)、電(dian)(dian)(dian)度表(biao)的功能(neng),可以(yi)在一個(ge)顯(xian)(xian)示(shi)(shi)界(jie)面上滾動顯(xian)(xian)示(shi)(shi)上述量值(zhi),它也是可以(yi)起到電(dian)(dian)(dian)度表(biao)電(dian)(dian)(dian)能(neng)測(ce)量的作(zuo)用(yong)的,不過一般來說,不建議用(yong)多功能(neng)電(dian)(dian)(dian)力(li)儀表(biao)當電(dian)(dian)(dian)度表(biao)用(yong)。
多功能電力儀表是測(ce)量(liang)(liang)表(biao)(biao)(biao),測(ce)量(liang)(liang)表(biao)(biao)(biao)僅作為顯(xian)示、監控等(deng)使用(yong),可清(qing)零(ling)可復位可改(gai)變比,且測(ce)量(liang)(liang)表(biao)(biao)(biao)計(ji)接入的CT、PT的精(jing)度(du)(du)級(ji)也都(dou)是測(ce)量(liang)(liang)級(ji)(一般(ban)是0.5級(ji));而電(dian)(dian)度(du)(du)表(biao)(biao)(biao)屬于(yu)計(ji)量(liang)(liang)表(biao)(biao)(biao),不(bu)可清(qing)零(ling)不(bu)可復位不(bu)可改(gai)變比(用(yong)計(ji)量(liang)(liang)表(biao)(biao)(biao)廠家只(zhi)提供給(gei)電(dian)(dian)力公司的專業軟件可以改(gai),所以計(ji)量(liang)(liang)表(biao)(biao)(biao)需(xu)得到(dao)電(dian)(dian)力公司的認證(zheng)),接入的CT、PT的精(jing)度(du)(du)級(ji)也都(dou)是計(ji)量(liang)(liang)級(ji)(一般(ban)是0.2s或0.2級(ji))。因此,不(bu)能把多功能電(dian)(dian)力儀表(biao)(biao)(biao)當電(dian)(dian)度(du)(du)表(biao)(biao)(biao)用(yong)。
