電路安裝是家裝過程中至關重要的步驟,一旦電路安裝不正確,會對家居的正常用電造成影響,甚至引發安全事故,因此在安裝電路時一定要格外注意,那么地線可以當零線用嗎?如何區分零線與地線呢?和金環宇電線電纜小編一起來看看吧!
一、地(di)線可以當零線用(yong)嗎(ma)
地線(xian)(xian)不可以作為(wei)零(ling)線(xian)(xian)使用(yong),因(yin)為(wei)地線(xian)(xian)具有保(bao)護作用(yong),使用(yong)時并(bing)未流經電(dian)(dian)(dian)流,這樣(yang)在出現電(dian)(dian)(dian)器(qi)漏(lou)電(dian)(dian)(dian)的情況時,可以將電(dian)(dian)(dian)流流向地面(mian),避免發生(sheng)人體觸電(dian)(dian)(dian)事故,如果作為(wei)零(ling)線(xian)(xian)使用(yong),地線(xian)(xian)則處于帶電(dian)(dian)(dian)狀態,并(bing)與(yu)整個用(yong)電(dian)(dian)(dian)系統相連接,這樣(yang)會對整個系統的安全性(xing)造成影響(xiang)。
二(er)、如何區分零線(xian)與地線(xian)
1、在區(qu)分零(ling)線(xian)(xian)與地(di)(di)線(xian)(xian)的(de)(de)時候,可以(yi)觀察零(ling)線(xian)(xian)與地(di)(di)線(xian)(xian)的(de)(de)顏(yan)(yan)(yan)色(se)(se),按(an)照我國(guo)相關標(biao)準來看,零(ling)線(xian)(xian)的(de)(de)顏(yan)(yan)(yan)色(se)(se)一(yi)般(ban)為(wei)(wei)綠色(se)(se)或(huo)者黃色(se)(se),有時候也(ye)為(wei)(wei)黑色(se)(se),地(di)(di)線(xian)(xian)的(de)(de)顏(yan)(yan)(yan)色(se)(se)為(wei)(wei)黃綠相間(jian)。若家(jia)中使用的(de)(de)三相插座,一(yi)般(ban)左側(ce)線(xian)(xian)路為(wei)(wei)零(ling)線(xian)(xian),右側(ce)線(xian)(xian)路為(wei)(wei)火線(xian)(xian),中間(jian)或(huo)者上(shang)方線(xian)(xian)路為(wei)(wei)地(di)(di)線(xian)(xian)。
2、如(ru)(ru)果通過顏色(se)無法區分零線(xian)(xian)與地(di)線(xian)(xian),可以使用(yong)電(dian)(dian)筆進行(xing)檢驗(yan),檢驗(yan)時讓電(dian)(dian)筆發亮的(de)就為火(huo)線(xian)(xian),不亮的(de)則(ze)為地(di)線(xian)(xian)或者零線(xian)(xian)。此外,還可以使用(yong)漏電(dian)(dian)保(bao)護(hu)器(qi)進行(xing)檢驗(yan),將燈泡與火(huo)線(xian)(xian)連接在一(yi)起,再分別連接零線(xian)(xian)與地(di)線(xian)(xian),如(ru)(ru)果連接后(hou)漏電(dian)(dian)保(bao)護(hu)器(qi)出(chu)現跳閘的(de)情(qing)況(kuang),說明該線(xian)(xian)路為地(di)線(xian)(xian),反之則(ze)為零線(xian)(xian)。
3、家(jia)用插座在(zai)接線時必(bi)須按照相(xiang)關規定進行,因此將插座拆(chai)開后(hou),與(yu)(yu)L連接口(kou)(kou)相(xiang)接的電路一般(ban)為火線,與(yu)(yu)N連接口(kou)(kou)相(xiang)接的線路為零線,地線則與(yu)(yu)標有接地符號的連接口(kou)(kou)相(xiang)接。
