二、電表規格型號主要有哪些

目前，電(dian)能(neng)(neng)(neng)表(biao)的(de)形式(shi)及功(gong)(gong)能(neng)(neng)(neng)是多樣化的(de)，各大生產廠家在型號上面命名(ming)也有區別(bie)，常規(gui)有功(gong)(gong)電(dian)能(neng)(neng)(neng)表(biao)示其(qi)(qi)功(gong)(gong)能(neng)(neng)(neng)和用(yong)途只用(yong)兩個(ge)字(zi)母(mu)。其(qi)(qi)它(ta)有特殊功(gong)(gong)能(neng)(neng)(neng)電(dian)子式(shi)電(dian)能(neng)(neng)(neng)表(biao)表(biao)示其(qi)(qi)功(gong)(gong)能(neng)(neng)(neng)和用(yong)途多用(yong)三(san)個(ge)字(zi)母(mu)。

1、電能表的型號

電(dian)(dian)表的型(xing)號一般從類別代(dai)(dai)號，組別代(dai)(dai)號，功(gong)能(neng)(neng)代(dai)(dai)號，設計(ji)(ji)序號等進行(xing)編寫。一般的電(dian)(dian)能(neng)(neng)表類別代(dai)(dai)號均為D。組別代(dai)(dai)號通常分為：A（安培小時計(ji)(ji)）、B（標準）、D（單相電(dian)(dian)能(neng)(neng)表）、F（伏特小時計(ji)(ji)）、J（直流）、S（三(san)相三(san)線）、T（三(san)相四線）、X（無功(gong)）。功(gong)能(neng)(neng)代(dai)(dai)號通常分為：F（分時計(ji)(ji)費(fei)）、S（電(dian)(dian)子(zi)式(shi)）、Y（預付費(fei)式(shi)）、D（多功(gong)能(neng)(neng)）、M（脈沖式(shi)）、Z（最(zui)大需(xu)量）。設計(ji)(ji)序號為數字(zi)。

2、電能表的規格

電(dian)(dian)能表(biao)一般(ban)分為單(dan)相(xiang)電(dian)(dian)表(biao)和(he)三相(xiang)電(dian)(dian)表(biao)。常用的家用電(dian)(dian)表(biao)一般(ban)使用單(dan)相(xiang)電(dian)(dian)表(biao)，額定工作(zuo)電(dian)(dian)壓為220V，額定頻率為50Hz，額定工作(zuo)電(dian)(dian)流型號不同而有2.5A，3A，5A，10A等(deng)不同規格(ge)。

3、市面常見的家用電表規格型號

威勝電(dian)表：DDS102單相(xiang)電(dian)子式(shi)有(you)功電(dian)能表

科(ke)陸電表：DDS720單相電子式電能表

杭州華(hua)立：DDS28單(dan)相(xiang)電(dian)子式電(dian)能表(biao)，DDS28-1型單(dan)相(xiang)電(dian)子式電(dian)能表(biao)

三、家用電表需要參考的因素有哪些

1、總核載功率。打開你家所有的電(dian)器總功率(lv)，并且還需要考慮(lv)接下(xia)來(lai)還會購(gou)買(mai)哪些電(dian)器的總核載功率(lv)來(lai)選擇電(dian)表的規格型(xing)號，以便(bian)滿足長時間需求。

2、電表功能。現在的電(dian)表(biao)已經(jing)有許多種功(gong)能(neng)(neng)(neng)(neng)(neng)，有功(gong)表(biao)，無功(gong)表(biao)，機械表(biao)，電(dian)子表(biao)，需(xu)量(liang)表(biao)，多功(gong)能(neng)(neng)(neng)(neng)(neng)表(biao)，峰(feng)谷分時表(biao)等等。這里(li)就需(xu)要看(kan)具(ju)體使用要求了。現在的多功(gong)能(neng)(neng)(neng)(neng)(neng)電(dian)子表(biao)，能(neng)(neng)(neng)(neng)(neng)集成(cheng)多種計量(liang)功(gong)能(neng)(neng)(neng)(neng)(neng)，但是價格不菲。一(yi)般(ban)的機械表(biao)能(neng)(neng)(neng)(neng)(neng)單(dan)獨計量(liang)一(yi)種或幾種功(gong)能(neng)(neng)(neng)(neng)(neng)，價格相對便宜。關(guan)鍵(jian)看(kan)需(xu)要情況而定。

3、計量精度。不同要(yao)求下(xia)，電表(biao)(biao)需(xu)(xu)要(yao)的(de)精(jing)度也(ye)是不一樣的(de)。一般(ban)家(jia)庭用電，用2.0級(ji)以上的(de)精(jing)度電表(biao)(biao)足(zu)夠了，而在大型企業，關口表(biao)(biao)計(ji)，需(xu)(xu)要(yao)的(de)是0.5，甚至是0.2級(ji)精(jing)度的(de)電表(biao)(biao)。精(jing)度越(yue)高，價格也(ye)就(jiu)越(yue)高。這點，同樣需(xu)(xu)要(yao)看使用的(de)需(xu)(xu)要(yao)而定(ding)。

4、產品的品質。在其他因素一樣的(de)情(qing)況下，產(chan)品的(de)質量非常重(zhong)要，也(ye)并不(bu)是(shi)貴的(de)一定(ding)好(hao)，好(hao)的(de)一定(ding)貴，不(bu)過最(zui)好(hao)還是(shi)選擇正規渠道大品牌產(chan)品，保障質量，避免出(chu)現(xian)不(bu)良后果(guo)。
