配電箱廠家(jia)詳(xiang)細講(jiang)解下配電(dian)箱(xiang)三(san)(san)相五線(xian)(xian)制的接(jie)法！三(san)(san)相五線(xian)(xian)制包括三(san)(san)相電(dian)的三(san)(san)個相線(xian)(xian)（A、B、C線(xian)(xian)）、中性線(xian)(xian)（N線(xian)(xian)）；以及地線(xian)(xian)（PE線(xian)(xian)）。中性線(xian)(xian)(N線(xian)(xian))就是(shi)零線(xian)(xian)。三(san)(san)相負載(zai)對稱時(shi)，三(san)(san)相線(xian)(xian)路流(liu)入中性線(xian)(xian)的電(dian)流(liu)矢量(liang)和為(wei)(wei)零，但對于單獨的一相來講(jiang)，電(dian)流(liu)不為(wei)(wei)零。三(san)(san)相負載(zai)不對稱時(shi)，中性線(xian)(xian)的電(dian)流(liu)矢量(liang)和不為(wei)(wei)零，會產(chan)生對地電(dian)壓。

三相五線制(zhi)標準導線顏色(se)為：A線黃(huang)色(se)，B線綠(lv)色(se)，C線紅(hong)色(se)，N線淡藍色(se)，PE線黃(huang)綠(lv)色(se)。

三相五線制分(fen)為TT接地(di)方(fang)式和TN接地(di)方(fang)式，其中(zhong)TN又具(ju)體(ti)分(fen)為TN-S，TN-C，TN-C-S三種方(fang)式。

三相(xiang)五線制分為(wei)TT接地方(fang)式(shi)和TN接地方(fang)式(shi)，其中TN又具體分為(wei)TN-S，TN-C，TN-C-S三種方(fang)式(shi)。

民用(yong)(yong)供電線(xian)(xian)(xian)路相線(xian)(xian)(xian)之間(jian)的(de)(de)電壓（即(ji)線(xian)(xian)(xian)電壓）為380V，相線(xian)(xian)(xian)和(he)地線(xian)(xian)(xian)或(huo)中性(xing)線(xian)(xian)(xian)之間(jian)的(de)(de)電壓（即(ji)相電壓）均為220V。進戶線(xian)(xian)(xian)一(yi)般采用(yong)(yong)單相二線(xian)(xian)(xian)制，即(ji)三個相線(xian)(xian)(xian)中的(de)(de)任意一(yi)相和(he)中性(xing)線(xian)(xian)(xian)（作零(ling)線(xian)(xian)(xian)）。如遇大功率(lv)用(yong)(yong)電器，需(xu)自行設置(zhi)接(jie)地線(xian)(xian)(xian)。

三相(xiang)五線(xian)(xian)(xian)制標準導(dao)線(xian)(xian)(xian)顏色(se)為：A線(xian)(xian)(xian)黃色(se)，B線(xian)(xian)(xian)綠色(se)，C線(xian)(xian)(xian)紅色(se)，N線(xian)(xian)(xian)淡藍色(se)，PE線(xian)(xian)(xian)黃綠色(se)。

三(san)(san)相(xiang)(xiang)五線(xian)(xian)(xian)(xian)(xian)制(zhi)包括三(san)(san)相(xiang)(xiang)電(dian)的三(san)(san)個相(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)（A、B、C線(xian)(xian)(xian)(xian)(xian)）、中(zhong)(zhong)性線(xian)(xian)(xian)(xian)(xian)（N線(xian)(xian)(xian)(xian)(xian)）；以及地(di)線(xian)(xian)(xian)(xian)(xian)（PE線(xian)(xian)(xian)(xian)(xian)）。中(zhong)(zhong)性線(xian)(xian)(xian)(xian)(xian)(N線(xian)(xian)(xian)(xian)(xian))就是零(ling)線(xian)(xian)(xian)(xian)(xian)。三(san)(san)相(xiang)(xiang)負(fu)載(zai)對(dui)稱時，三(san)(san)相(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)路流入中(zhong)(zhong)性線(xian)(xian)(xian)(xian)(xian)的電(dian)流矢量和為(wei)零(ling)，但(dan)對(dui)于單獨(du)的一相(xiang)(xiang)來講(jiang)，電(dian)流不(bu)為(wei)零(ling)。三(san)(san)相(xiang)(xiang)負(fu)載(zai)不(bu)對(dui)稱時，中(zhong)(zhong)性線(xian)(xian)(xian)(xian)(xian)的電(dian)流矢量和不(bu)為(wei)零(ling)，會產生(sheng)對(dui)地(di)電(dian)壓。
