買電線時，常(chang)看(kan)見(jian)電線有(you)很多(duo)種(zhong)顏(yan)(yan)色，其實呀，電線的(de)外皮的(de)顏(yan)(yan)色都是(shi)有(you)不同意義(yi)的(de)。下面說下每(mei)根帶顏(yan)(yan)色的(de)電線都是(shi)什(shen)么(me)含(han)義(yi)。

一般規定，三(san)(san)(san)相(xiang)電線(xian)(xian)(xian)(xian)(xian)顏(yan)色為黃、綠、紅，分別為A、B、C三(san)(san)(san)相(xiang)，藍(lan)色為零線(xian)(xian)(xian)(xian)(xian)，黃綠相(xiang)間(jian)的(de)(de)(de)為接(jie)地線(xian)(xian)(xian)(xian)(xian)，接(jie)線(xian)(xian)(xian)(xian)(xian)時黃、綠、紅接(jie)火(huo)(huo)線(xian)(xian)(xian)(xian)(xian)，藍(lan)色接(jie)零線(xian)(xian)(xian)(xian)(xian)，黃綠相(xiang)間(jian)的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)接(jie)到PE保護線(xian)(xian)(xian)(xian)(xian)上或者(zhe)接(jie)到設備外殼上(外殼已與地網連接(jie))。有時四線(xian)(xian)(xian)(xian)(xian)顏(yan)色區分不太明顯時，三(san)(san)(san)根(gen)(gen)截面一樣的(de)(de)(de)為火(huo)(huo)線(xian)(xian)(xian)(xian)(xian)，截面稍(shao)小的(de)(de)(de)為零線(xian)(xian)(xian)(xian)(xian)。你說的(de)(de)(de)變壓(ya)器也許是控制回路的(de)(de)(de)電源，如是380V，接(jie)到任意兩根(gen)(gen)火(huo)(huo)線(xian)(xian)(xian)(xian)(xian)上;如是220V，則(ze)接(jie)一根(gen)(gen)火(huo)(huo)線(xian)(xian)(xian)(xian)(xian)，一根(gen)(gen)零線(xian)(xian)(xian)(xian)(xian)。

實際操作 安全為上紅(hong)色是(shi)(shi)(shi)火(huo)線(xian)(xian)，藍色是(shi)(shi)(shi)零線(xian)(xian)，黃(huang)色或黃(huang)白相(xiang)間(jian)的是(shi)(shi)(shi)地線(xian)(xian)。相(xiang)線(xian)(xian)一般是(shi)(shi)(shi)黃(huang)、綠(lv)、紅(hong)，保(bao)護中性(xing)線(xian)(xian)(PEN線(xian)(xian))是(shi)(shi)(shi)黑(hei)色，保(bao)護線(xian)(xian)(PE線(xian)(xian))是(shi)(shi)(shi)黃(huang)綠(lv)雙(shuang)色線(xian)(xian)，保(bao)護線(xian)(xian)在任何情況下都嚴禁作相(xiang)線(xian)(xian)使(shi)用。

根據《住宅(zhai)裝飾裝修工(gong)程施工(gong)規范(fan)》GB 50327-2001 16.1.4條規定(ding)：

“配線(xian)(xian)(xian)時，相(xiang)線(xian)(xian)(xian)與零線(xian)(xian)(xian)的顏色(se)(se)應(ying)不同(tong)，同(tong)一(yi)住宅相(xiang)線(xian)(xian)(xian)(L)顏色(se)(se)應(ying)統(tong)一(yi)，零線(xian)(xian)(xian)(N)宜用(yong)藍(lan)色(se)(se)，保護(hu)線(xian)(xian)(xian)(PE)必須(xu)用(yong)黃綠(lv)雙色(se)(se)線(xian)(xian)(xian)”

保(bao)護線(xian)(PE)即地線(xian)必須(強制性規(gui)定(ding)(ding)(ding))用(yong)黃綠雙(shuang)色(se)(se)線(xian)，零線(xian)用(yong)藍色(se)(se),(不(bu)是(shi)強制性規(gui)定(ding)(ding)(ding)，在(zai)條件許可時，勻應選擇藍色(se)(se)線(xian))，相(xiang)線(xian)不(bu)使用(yong)藍色(se)(se)即為紅、黃、綠色(se)(se)。(相(xiang)線(xian)顏色(se)(se)還未一致起來(lai)，不(bu)同公司可能(neng)規(gui)定(ding)(ding)(ding)不(bu)一樣。
