配電箱廠家詳細(xi)講解下配電(dian)箱三(san)(san)(san)相(xiang)(xiang)(xiang)五(wu)線(xian)(xian)(xian)(xian)制的(de)(de)接法(fa)！三(san)(san)(san)相(xiang)(xiang)(xiang)五(wu)線(xian)(xian)(xian)(xian)制包(bao)括三(san)(san)(san)相(xiang)(xiang)(xiang)電(dian)的(de)(de)三(san)(san)(san)個相(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)（A、B、C線(xian)(xian)(xian)(xian)）、中(zhong)性線(xian)(xian)(xian)(xian)（N線(xian)(xian)(xian)(xian)）；以及地(di)線(xian)(xian)(xian)(xian)（PE線(xian)(xian)(xian)(xian)）。中(zhong)性線(xian)(xian)(xian)(xian)(N線(xian)(xian)(xian)(xian))就是零線(xian)(xian)(xian)(xian)。三(san)(san)(san)相(xiang)(xiang)(xiang)負載(zai)(zai)對稱時，三(san)(san)(san)相(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)路流(liu)入(ru)中(zhong)性線(xian)(xian)(xian)(xian)的(de)(de)電(dian)流(liu)矢量和為(wei)零，但(dan)對于單獨(du)的(de)(de)一相(xiang)(xiang)(xiang)來講，電(dian)流(liu)不為(wei)零。三(san)(san)(san)相(xiang)(xiang)(xiang)負載(zai)(zai)不對稱時，中(zhong)性線(xian)(xian)(xian)(xian)的(de)(de)電(dian)流(liu)矢量和不為(wei)零，會產(chan)生(sheng)對地(di)電(dian)壓。
三(san)相五(wu)線(xian)制標準導線(xian)顏色(se)為：A線(xian)黃色(se)，B線(xian)綠色(se)，C線(xian)紅色(se)，N線(xian)淡藍色(se)，PE線(xian)黃綠色(se)。
三(san)相五(wu)線制分(fen)為(wei)TT接地方式(shi)和TN接地方式(shi)，其中TN又具體分(fen)為(wei)TN-S，TN-C，TN-C-S三(san)種方式(shi)。
三相五(wu)線制分(fen)(fen)為(wei)TT接地(di)方(fang)式和TN接地(di)方(fang)式，其中(zhong)TN又具(ju)體分(fen)(fen)為(wei)TN-S，TN-C，TN-C-S三種方(fang)式。
民(min)用(yong)供電(dian)線(xian)(xian)路相線(xian)(xian)之間(jian)的(de)電(dian)壓(ya)（即(ji)線(xian)(xian)電(dian)壓(ya)）為380V，相線(xian)(xian)和(he)地(di)線(xian)(xian)或中(zhong)(zhong)性(xing)線(xian)(xian)之間(jian)的(de)電(dian)壓(ya)（即(ji)相電(dian)壓(ya)）均(jun)為220V。進戶(hu)線(xian)(xian)一般采用(yong)單相二線(xian)(xian)制(zhi)，即(ji)三個相線(xian)(xian)中(zhong)(zhong)的(de)任意一相和(he)中(zhong)(zhong)性(xing)線(xian)(xian)（作(zuo)零(ling)線(xian)(xian)）。如遇大功率用(yong)電(dian)器，需自行設置接(jie)地(di)線(xian)(xian)。
三相(xiang)五線制標準導線顏(yan)色(se)(se)(se)(se)為：A線黃(huang)色(se)(se)(se)(se)，B線綠色(se)(se)(se)(se)，C線紅色(se)(se)(se)(se)，N線淡藍色(se)(se)(se)(se)，PE線黃(huang)綠色(se)(se)(se)(se)。
三相五線(xian)(xian)(xian)制包括三相電(dian)(dian)的三個(ge)相線(xian)(xian)(xian)（A、B、C線(xian)(xian)(xian)）、中(zhong)(zhong)(zhong)性(xing)(xing)線(xian)(xian)(xian)（N線(xian)(xian)(xian)）；以及地(di)線(xian)(xian)(xian)（PE線(xian)(xian)(xian)）。中(zhong)(zhong)(zhong)性(xing)(xing)線(xian)(xian)(xian)(N線(xian)(xian)(xian))就是零(ling)線(xian)(xian)(xian)。三相負(fu)(fu)載對稱(cheng)時，三相線(xian)(xian)(xian)路流(liu)(liu)入中(zhong)(zhong)(zhong)性(xing)(xing)線(xian)(xian)(xian)的電(dian)(dian)流(liu)(liu)矢(shi)(shi)量和(he)為(wei)零(ling)，但對于單獨的一(yi)相來講，電(dian)(dian)流(liu)(liu)不為(wei)零(ling)。三相負(fu)(fu)載不對稱(cheng)時，中(zhong)(zhong)(zhong)性(xing)(xing)線(xian)(xian)(xian)的電(dian)(dian)流(liu)(liu)矢(shi)(shi)量和(he)不為(wei)零(ling)，會產(chan)生對地(di)電(dian)(dian)壓。
