電度表(biao)又叫做電能表、火表(biao)(biao)，是(shi)用來(lai)測量電(dian)(dian)能(neng)(neng)消耗量和(he)消耗速度的(de)(de)儀(yi)表(biao)(biao)。電(dian)(dian)能(neng)(neng)表(biao)(biao)已有(you)超過(guo)100年(nian)的(de)(de)歷史。從(cong)感(gan)應式(shi)電(dian)(dian)能(neng)(neng)表(biao)(biao)到(dao)電(dian)(dian)子式(shi)電(dian)(dian)能(neng)(neng)表(biao)(biao)，進(jin)入21世(shi)紀后，更是(shi)進(jin)入了智能(neng)(neng)電(dian)(dian)能(neng)(neng)表(biao)(biao)時代。智能(neng)(neng)電(dian)(dian)能(neng)(neng)表(biao)(biao)除了具(ju)有(you)電(dian)(dian)力(li)客戶和(he)電(dian)(dian)力(li)公(gong)司電(dian)(dian)能(neng)(neng)計量計費(fei)的(de)(de)傳統功(gong)(gong)能(neng)(neng)之外(wai)，也是(shi)用電(dian)(dian)信息溝通(tong)和(he)供電(dian)(dian)服(fu)務交互的(de)(de)有(you)效工具(ju)，是(shi)智能(neng)(neng)電(dian)(dian)網和(he)智能(neng)(neng)用電(dian)(dian)的(de)(de)基礎。在外(wai)面(mian)選擇(ze)使用電(dian)(dian)能(neng)(neng)表(biao)(biao)的(de)(de)時候，要更加看重實用性和(he)功(gong)(gong)能(neng)(neng)性。下面(mian)小編來(lai)介紹一(yi)下電(dian)(dian)能(neng)(neng)表(biao)(biao)應該怎么選擇(ze)?出現故障(zhang)怎么解決?

電能表應該怎么選擇?出現故障怎么解決?

一、選用電能表，具體要考慮哪些因素呢?

1、環(huan)境氣候特(te)征，我(wo)們國家幅員遼闊(kuo)，東南西北氣候條件(jian)大不(bu)相(xiang)同。所以，在我(wo)們選購電能(neng)表時，首先要考慮它(ta)的使用(yong)地點和(he)使用(yong)環(huan)境，最高溫度(du)、最低溫度(du)、相(xiang)對濕度(du)、海(hai)拔(ba)高度(du)等等，超出了使用(yong)范(fan)圍，電能(neng)表就不(bu)能(neng)正(zheng)常工作，或者(zhe)說計量精(jing)度(du)就會大打(da)折扣(kou)。

2、工作電(dian)壓和(he)工作電(dian)流，一(yi)般家(jia)庭用電(dian)，電(dian)壓就是(shi)(shi)交(jiao)流220V、頻率(lv)是(shi)(shi)50Hz，電(dian)流要(yao)(yao)按照(zhao)使用的具體情(qing)況來(lai)確定。假如是(shi)(shi)一(yi)臺集中空調，功率(lv)是(shi)(shi)5kW，電(dian)流大(da)約是(shi)(shi)22.5A，那么，我們選擇電(dian)能表(biao)的電(dian)流最(zui)小也要(yao)(yao)25A。如果是(shi)(shi)住(zhu)宅，可以按照(zhao)60-80W/平(ping)米(mi)估算，100平(ping)米(mi)的房(fang)子，功率(lv)大(da)約就是(shi)(shi)6-8kW，電(dian)流大(da)約是(shi)(shi)27A-36A。

二、電能表出現故障(zhang)怎么解(jie)決?

1.接線盒內(nei)出現燒焦糊味

解決方(fang)法：表盤下端的膠(jiao)木(mu)接線盒(he)內產生(sheng)燒(shao)焦(jiao)糊味(wei)，主要有兩方(fang)面的原因：

①在安(an)裝或更換電(dian)路導線(xian)時(shi)，盒(he)(he)內的(de)固定螺(luo)(luo)(luo)絲未擰(ning)緊，當電(dian)器用電(dian)負荷增(zeng)大時(shi)，螺(luo)(luo)(luo)絲住因接觸不(bu)良發熱，燒壞膠木盒(he)(he)并伴發焦糊味。解(jie)決的(de)方法很簡單，取下(xia)膠木接線(xian)蓋后拉下(xia)總閘刀，將電(dian)源(yuan)導線(xian)全部拆下(xia)，重新(xin)用刀將線(xian)頭殘留(liu)物刮干凈，裝入(ru)接線(xian)柱內，擰(ning)緊全部螺(luo)(luo)(luo)絲即可(ke)排(pai)除故障。

②從(cong)(cong)室內接(jie)(jie)(jie)到電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)的(de)導線(xian)質量差，引(yin)起銅(tong)柱與(yu)導線(xian)間產生(sheng)氧化層(特別(bie)是(shi)安裝(zhuang)在環境潮(chao)濕，不(bu)通風處的(de)電(dian)(dian)(dian)(dian)(dian)(dian)能表(biao)(biao)容易產生(sheng)此(ci)類問題)，從(cong)(cong)而增大電(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)使接(jie)(jie)(jie)觸(chu)點發熱(re)而損(sun)壞接(jie)(jie)(jie)線(xian)盒。這(zhe)時(shi)應(ying)徹(che)底清(qing)除接(jie)(jie)(jie)線(xian)盒內的(de)油污及時(shi)更換導線(xian)。有(you)(you)時(shi)當用電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備超過電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)實際(ji)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值(zhi)時(shi)，不(bu)僅(jin)接(jie)(jie)(jie)線(xian)盒會損(sun)壞，電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)也有(you)(you)可能被強電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)擊(ji)毀，所(suo)以當發現表(biao)(biao)的(de)額定電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)與(yu)實際(ji)所(suo)用的(de)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)負荷相差很(hen)大時(shi)，應(ying)錯開使用時(shi)間或(huo)更換電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)，以防電(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)被擊(ji)毀或(huo)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)火災(zai)。

2.空(kong)載時自行(xing)轉動

解決(jue)方法(fa)：電(dian)(dian)表(biao)在(zai)(zai)(zai)(zai)空(kong)載時(shi)會自行(xing)轉動(dong)(dong)(dong)(dong)即住宅內(nei)的所有用(yong)電(dian)(dian)設備及照明(ming)(ming)燈具都未使用(yong)，而表(biao)的鋁(lv)盤(pan)仍在(zai)(zai)(zai)(zai)轉動(dong)(dong)(dong)(dong)或慢(man)慢(man)運行(xing)。一般來說，當電(dian)(dian)源電(dian)(dian)壓為額定值的80%~110%時(shi)，電(dian)(dian)表(biao)鋁(lv)盤(pan)的轉動(dong)(dong)(dong)(dong)不(bu)會超(chao)過1圈屬于正(zheng)常(chang)范圍(即轉盤(pan)順時(shi)針方向轉動(dong)(dong)(dong)(dong)一圈)，但(dan)若鋁(lv)盤(pan)微微轉動(dong)(dong)(dong)(dong)不(bu)止，則說明(ming)(ming)電(dian)(dian)表(biao)線路有漏電(dian)(dian)存在(zai)(zai)(zai)(zai)，應請電(dian)(dian)工檢查處理。如果沒(mei)有漏電(dian)(dian)存在(zai)(zai)(zai)(zai)，就是電(dian)(dian)表(biao)自身的故障(zhang)，應及時(shi)送電(dian)(dian)力部(bu)門檢修或換新表(biao)。

3.運行時產生“吱吱”響(xiang)聲

解決(jue)方法：電(dian)(dian)能表在運行時，有輕微的“嗡嗡”聲(sheng)，屬于正(zheng)常現象。但如(ru)果(guo)表內產生(sheng)不規則的雜(za)亂(luan)“吱吱”響(xiang)聲(sheng)，則是表內部(bu)的某些(xie)配件(jian)老化、電(dian)(dian)磁場部(bu)分元(yuan)件(jian)松動(dong)或轉動(dong)齒輪缺油等原因(yin)所引起。應送電(dian)(dian)力部(bu)門檢(jian)驗并更換易損配件(jian)。有時，電(dian)(dian)表嚴重超負(fu)荷運行，也會產生(sheng)不規則的響(xiang)聲(sheng)，應及時關閉部(bu)分電(dian)(dian)源，以防損壞(huai)電(dian)(dian)表。
