二、電表規格型號主要有哪些

目前，電能表(biao)的形式及功(gong)(gong)(gong)能是多樣化的，各大(da)生(sheng)產廠家在型號(hao)上面(mian)命名(ming)也有區別，常規有功(gong)(gong)(gong)電能表(biao)示(shi)其功(gong)(gong)(gong)能和用(yong)途只(zhi)用(yong)兩個(ge)字母。其它有特殊功(gong)(gong)(gong)能電子式電能表(biao)表(biao)示(shi)其功(gong)(gong)(gong)能和用(yong)途多用(yong)三個(ge)字母。

1、電能表的型號

電(dian)表(biao)的(de)型號(hao)(hao)一(yi)般(ban)從類(lei)(lei)別(bie)(bie)代(dai)(dai)(dai)號(hao)(hao)，組(zu)別(bie)(bie)代(dai)(dai)(dai)號(hao)(hao)，功(gong)(gong)(gong)能(neng)(neng)(neng)代(dai)(dai)(dai)號(hao)(hao)，設(she)計(ji)(ji)序(xu)號(hao)(hao)等進行編寫(xie)。一(yi)般(ban)的(de)電(dian)能(neng)(neng)(neng)表(biao)類(lei)(lei)別(bie)(bie)代(dai)(dai)(dai)號(hao)(hao)均為(wei)D。組(zu)別(bie)(bie)代(dai)(dai)(dai)號(hao)(hao)通常(chang)分(fen)為(wei)：A（安(an)培(pei)小時計(ji)(ji)）、B（標準）、D（單(dan)相電(dian)能(neng)(neng)(neng)表(biao)）、F（伏特小時計(ji)(ji)）、J（直(zhi)流(liu)）、S（三相三線）、T（三相四(si)線）、X（無功(gong)(gong)(gong)）。功(gong)(gong)(gong)能(neng)(neng)(neng)代(dai)(dai)(dai)號(hao)(hao)通常(chang)分(fen)為(wei)：F（分(fen)時計(ji)(ji)費）、S（電(dian)子式）、Y（預付費式）、D（多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)）、M（脈沖式）、Z（最大(da)需量）。設(she)計(ji)(ji)序(xu)號(hao)(hao)為(wei)數字。

2、電能表的規格

電(dian)能表一般分為單相電(dian)表和三相電(dian)表。常用的家用電(dian)表一般使用單相電(dian)表，額(e)定(ding)工(gong)作電(dian)壓為220V，額(e)定(ding)頻率為50Hz，額(e)定(ding)工(gong)作電(dian)流型號不同而有2.5A，3A，5A，10A等(deng)不同規格。

3、市面常見的家用電表規格型號

威勝電表(biao)：DDS102單相電子式有(you)功電能表(biao)

科陸(lu)電表(biao)：DDS720單相電子(zi)式電能(neng)表(biao)

杭州華(hua)立：DDS28單(dan)相電(dian)子式電(dian)能表，DDS28-1型單(dan)相電(dian)子式電(dian)能表

三、家用電表需要參考的因素有哪些

1、總核載功率。打開你家所有的電器總功(gong)率(lv)，并(bing)且還需(xu)要(yao)考慮接下來(lai)(lai)還會購(gou)買(mai)哪些電器的總核載功(gong)率(lv)來(lai)(lai)選擇電表的規(gui)格型號，以便(bian)滿(man)足長時間需(xu)求。

2、電表功能。現在(zai)的(de)電(dian)表(biao)(biao)已經有許多(duo)種(zhong)功(gong)(gong)(gong)能(neng)(neng)(neng)，有功(gong)(gong)(gong)表(biao)(biao)，無功(gong)(gong)(gong)表(biao)(biao)，機(ji)械(xie)表(biao)(biao)，電(dian)子表(biao)(biao)，需(xu)量(liang)表(biao)(biao)，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)表(biao)(biao)，峰谷分時(shi)表(biao)(biao)等等。這里就需(xu)要(yao)看(kan)具體使(shi)用(yong)要(yao)求了(le)。現在(zai)的(de)多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)電(dian)子表(biao)(biao)，能(neng)(neng)(neng)集成多(duo)種(zhong)計量(liang)功(gong)(gong)(gong)能(neng)(neng)(neng)，但(dan)是價格(ge)不菲。一(yi)般的(de)機(ji)械(xie)表(biao)(biao)能(neng)(neng)(neng)單獨計量(liang)一(yi)種(zhong)或幾種(zhong)功(gong)(gong)(gong)能(neng)(neng)(neng)，價格(ge)相對便宜。關(guan)鍵看(kan)需(xu)要(yao)情況而(er)定。

3、計量精度。不同(tong)(tong)要(yao)求下，電(dian)(dian)表(biao)需(xu)要(yao)的(de)(de)(de)精(jing)度(du)也是不一樣的(de)(de)(de)。一般(ban)家庭用電(dian)(dian)，用2.0級以(yi)上的(de)(de)(de)精(jing)度(du)電(dian)(dian)表(biao)足夠了，而在大型企業，關口表(biao)計，需(xu)要(yao)的(de)(de)(de)是0.5，甚至(zhi)是0.2級精(jing)度(du)的(de)(de)(de)電(dian)(dian)表(biao)。精(jing)度(du)越(yue)高，價格(ge)也就越(yue)高。這點，同(tong)(tong)樣需(xu)要(yao)看使用的(de)(de)(de)需(xu)要(yao)而定(ding)。

4、產品的品質。在其他因素(su)一樣(yang)的(de)(de)情況下，產品(pin)的(de)(de)質量非常重要，也并(bing)不是貴的(de)(de)一定好(hao)(hao)，好(hao)(hao)的(de)(de)一定貴，不過最好(hao)(hao)還是選擇正規渠(qu)道大品(pin)牌產品(pin)，保障質量，避免(mian)出現不良后果。
