常用電能表的分類

編輯

（1）電能表(biao)按其使用(yong)的電路可(ke)(ke)分為(wei)直流電能表(biao)和(he)(he)交(jiao)流電能表(biao)。交(jiao)流電能表(biao)按其相(xiang)線又可(ke)(ke)分為(wei)單(dan)相(xiang)電能表(biao)、三(san)相(xiang)三(san)線電能表(biao)和(he)(he)三(san)相(xiang)四(si)線電能表(biao)。

（2）電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)按其(qi)工作(zuo)原(yuan)理可分(fen)為電(dian)(dian)(dian)(dian)(dian)氣機(ji)(ji)械(xie)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)和電(dian)(dian)(dian)(dian)(dian)子式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)（又稱(cheng)靜止式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)、固態式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)）。電(dian)(dian)(dian)(dian)(dian)氣機(ji)(ji)械(xie)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)用于(yu)交流(liu)電(dian)(dian)(dian)(dian)(dian)路作(zuo)為普通的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)測量儀(yi)表(biao)(biao)，其(qi)中用的(de)(de)是感(gan)應(ying)型(xing)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)。電(dian)(dian)(dian)(dian)(dian)子式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)可分(fen)為全電(dian)(dian)(dian)(dian)(dian)子式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)和機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)(biao)。

 （3）電(dian)能表按其結構可(ke)分為整體(ti)式電(dian)能表和分體(ti)式電(dian)能表。

（4）電(dian)(dian)能(neng)(neng)表按(an)其(qi)用途可分為有功(gong)電(dian)(dian)能(neng)(neng)表、無功(gong)電(dian)(dian)能(neng)(neng)表、*大需量表、標(biao)準電(dian)(dian)能(neng)(neng)表、復費(fei)率(lv)分時電(dian)(dian)能(neng)(neng)表、預付(fu)費(fei)電(dian)(dian)能(neng)(neng)表、損(sun)耗電(dian)(dian)能(neng)(neng)表和多功(gong)能(neng)(neng)電(dian)(dian)能(neng)(neng)表等。

（5）電能(neng)表(biao)按(an)其準(zhun)確度等級(ji)可分為(wei)普(pu)通(tong)安裝式電能(neng)表(biao)（0.2、0.5、1.0、2.0、3.0級(ji)）和攜帶式精密級(ji)電能(neng)表(biao)（0.01、0.02、0.05、0.1、0.2級(ji)）。
