cnc數(shu)控車床配電箱里電路怎么區分零線與火線答:區分火線、零線、地線方法:
1、從顏色(se)上(shang)區分，按照國家規(gui)定，黃(huang)綠紅為相線，藍色(se)線為零線，黃(huang)綠雙色(se)為地線。
2、用(yong)電(dian)(dian)筆測量，電(dian)(dian)筆氖管(guan)亮說明是(shi)火線。
3、零線(xian)地線(xian)都是不(bu)帶電的，電筆一般無法區分，需要用cnc數控車床零線(xian)可以(yi)不(bu)接(jie)嗎萬用表(biao)測量。
不(bu)接(jie)零(ling)(ling)(ling)線(xian)就(jiu)(jiu)(jiu)電(dian)器(qi)就(jiu)(jiu)(jiu)不(bu)能用嗎(ma)答:因為在電(dian)路(lu)(lu)中，必需要有一(yi)個(ge)回路(lu)(lu)，電(dian)器(qi)才可(ke)以(yi)正常工作，不(bu)接(jie)零(ling)(ling)(ling)線(xian)或(huo)火(huo)線(xian)，電(dian)路(lu)(lu)都沒有一(yi)個(ge)回路(lu)(lu)，電(dian)器(qi)都不(bu)能正常工作，但這(zhe)只是(shi)相(xiang)對而言的;某種情(qing)況，不(bu)接(jie)零(ling)(ling)(ling)線(xian)的電(dian)器(qi)也(ye)可(ke)以(yi)使(shi)用，同樣也(ye)可(ke)以(yi)跟(gen)火(huo)線(xian)產生回路(lu)(lu)，那就(jiu)(jiu)(jiu)是(shi)用地線(xian)代替零(ling)(ling)(ling)線(xian)，不(bu)過cnc數控車床零(ling)(ling)(ling)線(xian)可(ke)以(yi)不(bu)接(jie)嗎(ma)這(zhe)種接(jie)法是(shi)。
開(kai)關(guan)(guan)(guan)上為什么不接零(ling)線(xian)(xian)?答:1、開(kai)關(guan)(guan)(guan)不需要零(ling)線(xian)(xian)，開(kai)關(guan)(guan)(guan)的(de)(de)作(zuo)用(yong)是在閉合(he)cnc數控車(che)床零(ling)線(xian)(xian)可(ke)以不接嗎電(dian)路(lu)的(de)(de)某一(yi)(yi)點斷開(kai)或接通電(dian)路(lu)，一(yi)(yi)般的(de)(de)開(kai)關(guan)(guan)(guan)只有兩個(ge)接線(xian)(xian)柱(一(yi)(yi)進一(yi)(yi)出)，且都控制的(de)(de)火(huo)線(xian)(xian)。2、開(kai)關(guan)(guan)(guan)不能控制零(ling)線(xian)(xian)，如果控制的(de)(de)零(ling)線(xian)(xian)，在電(dian)路(lu)斷開(kai)后，用(yong)電(dian)器上還是有電(dian)壓的(de)(de)存(cun)在，會給使(shi)用(yong)和(he)維(wei)修(xiu)帶來不便和(he)危險。
三(san)相直通表不(bu)(bu)接(jie)零(ling)線(xian)(xian)(xian)(xian)可以嗎?答:三(san)相四(si)線(xian)(xian)(xian)(xian)電(dian)表不(bu)(bu)接(jie)零(ling)線(xian)(xian)(xian)(xian)是不(bu)(bu)可以的(de)。依(yi)照國家規定，建筑用電(dian)均(jun)選用三(san)相五線(xian)(xian)(xian)(xian)制的(de)低(di)壓配電(dian)系統(tong)，即(ji)地(di)線(xian)(xian)(xian)(xian)和(he)零(ling)線(xian)(xian)(xian)(xian)分開的(de)系統(tong)因(yin)為地(di)線(xian)(xian)(xian)(xian)和(he)零(ling)線(xian)(xian)(xian)(xian)均(jun)從電(dian)源cnc數控(kong)車床零(ling)線(xian)(xian)(xian)(xian)可以不(bu)(bu)接(jie)嗎的(de)中性線(xian)(xian)(xian)(xian)引出，電(dian)源的(de)中性線(xian)(xian)(xian)(xian)是接(jie)地(di)的(de)，零(ling)線(xian)(xian)(xian)(xian)和(he)地(di)線(xian)(xian)(xian)(xian)從物連接(jie)上是相通的(de)，因(yin)此在三(san)相四(si)線(xian)(xian)(xian)(xian)電(dian)表不(bu)(bu)接(jie)零(ling)線(xian)(xian)(xian)(xian)。
三(san)相(xiang)(xiang)(xiang)電(dian)(dian)表(biao)不接(jie)零(ling)線可以(yi)嗎答:三(san)相(xiang)(xiang)(xiang)四(si)線制(zhi)電(dian)(dian)能(neng)計量(liang)(liang)表(biao)有有功(gong)計量(liang)(liang)、無(wu)(wu)功(gong)計量(liang)(liang)。無(wu)(wu)功(gong)表(biao)不接(jie)零(ling)。三(san)相(xiang)(xiang)(xiang)四(si)線制(zhi)有功(gong)計量(liang)(liang)表(biao)內部一般(ban)是(shi)三(san)元(yuan)(yuan)件表(biao)，電(dian)(dian)壓線圈(quan)220伏。如果三(san)個(ge)線圈(quan)末端星接(jie)，每個(ge)線圈(quan)電(dian)(dian)壓也是(shi)220，可用但(dan)不允許。會造成計量(liang)(liang)誤(wu)差大或有損壞元(yuan)(yuan)件可能(neng)性。三(san)相(xiang)(xiang)(xiang)四(si)線制(zhi)表(biao)內電(dian)(dian)。
三(san)相(xiang)(xiang)四線(xian)(xian)(xian)電(dian)(dian)(dian)表(biao)不接(jie)零(ling)(ling)線(xian)(xian)(xian)可以嗎答:不可以。三(san)相(xiang)(xiang)四線(xian)(xian)(xian)低壓(ya)電(dian)(dian)(dian)能(neng)(neng)表(biao)計(ji)量三(san)相(xiang)(xiang)220V電(dian)(dian)(dian)壓(ya)的(de)電(dian)(dian)(dian)能(neng)(neng)表(biao)，其輸入電(dian)(dian)(dian)壓(ya)規(gui)格為220/380V，也(ye)就是說相(xiang)(xiang)電(dian)(dian)(dian)壓(ya)220V，任(ren)兩相(xiang)(xiang)之間的(de)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)為380V。三(san)相(xiang)(xiang)電(dian)(dian)(dian)能(neng)(neng)表(biao)就相(xiang)(xiang)當于(yu)三(san)只(zhi)單相(xiang)(xiang)電(dian)(dian)(dian)能(neng)(neng)表(biao)，沒有(you)零(ling)(ling)線(xian)(xian)(xian)就無法(fa)形(xing)成回路，無法(fa)準確(que)計(ji)cnc數控車床零(ling)(ling)線(xian)(xian)(xian)可以不接(jie)嗎量。必須(xu)接(jie)零(ling)(ling)線(xian)(xian)(xian)的(de)原(yuan)因(yin):1、為了準。

三(san)(san)相四(si)線(xian)(xian)電(dian)子式(shi)電(dian)度表(biao)(biao)如不(bu)接零(ling)(ling)線(xian)(xian)計量(liang)有準(zhun)(zhun)嗎?答:三(san)(san)相四(si)線(xian)(xian)電(dian)子式(shi)電(dian)度表(biao)(biao)不(bu)接零(ling)(ling)線(xian)(xian)的(de)話計量(liang)是(shi)不(bu)準(zhun)(zhun)的(de)。根據三(san)(san)相四(si)線(xian)(xian)電(dian)子式(shi)電(dian)表(biao)(biao)的(de)工(gong)作(zuo)原理，如果沒有零(ling)(ling)線(xian)(xian)的(de)話，計量(liang)線(xian)(xian)圈只是(shi)在三(san)(san)相中(zhong)平均，缺(que)少零(ling)(ling)線(xian)(xian)的(de)中(zhong)線(xian)(xian)平衡(heng)，計量(liang)線(xian)(xian)圈是(shi)無法形成完整閉合回路從(cong)而影(ying)響正(zheng)常(chang)工(gong)作(zuo)的(de)，三(san)(san)相用電(dian)中(zhong)某(mou)一相單相用電(dian)的(de)時候。
