電纜pe|電線電纜pe代表什么？

電纜電線pe

PE線，英文全(quan)稱(cheng)protecting earthing，簡體中(zhong)文名稱(cheng)稱(cheng)之(zhi)為[保護導體]。也就是(shi)我們通常所說(shuo)的[地線] 　　PE線是(shi)專門用于(yu)將電(dian)氣(qi)裝置外(wai)露導電(dian)部分接(jie)(jie)地的導體，至于(yu)是(shi)直接(jie)(jie)連接(jie)(jie)至與電(dian)源(yuan)點工作接(jie)(jie)地無(wu)關的接(jie)(jie)地極上（TT）還是(shi)通過電(dian)源(yuan)中(zhong)性點接(jie)(jie)地（TN）并不重要(yao)，二者都叫(jiao)PE線。

pe和PEN的關系

PEN線(xian)(xian)(xian)(xian)是(shi)(shi)兼有(you)保(bao)(bao)護(hu)(hu)(hu)接(jie)地線(xian)(xian)(xian)(xian)和(he)中(zhong)性線(xian)(xian)(xian)(xian)功能(neng)的(de)(de)(de)(de)(de)導體。工程中(zhong)多(duo)用(yong)(yong)于(yu)變電(dian)(dian)所低壓側至用(yong)(yong)戶電(dian)(dian)源進線(xian)(xian)(xian)(xian)點間(jian)的(de)(de)(de)(de)(de)一段線(xian)(xian)(xian)(xian)路（TN-C-S的(de)(de)(de)(de)(de)TN-C段）。PEN線(xian)(xian)(xian)(xian)是(shi)(shi)將(jiang)原(yuan)中(zhong)性線(xian)(xian)(xian)(xian)準確的(de)(de)(de)(de)(de)，良好(hao)的(de)(de)(de)(de)(de)接(jie)地，同(tong)(tong)時將(jiang)需要(yao)保(bao)(bao)護(hu)(hu)(hu)的(de)(de)(de)(de)(de)設(she)備的(de)(de)(de)(de)(de)外(wai)殼等連(lian)接(jie)于(yu)PEN線(xian)(xian)(xian)(xian)，所以(yi)，PEN線(xian)(xian)(xian)(xian)同(tong)(tong)時具(ju)有(you)上(shang)述(shu)所說的(de)(de)(de)(de)(de)PE線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)接(jie)地性質，也(ye)具(ju)有(you)N線(xian)(xian)(xian)(xian)[中(zhong)性線(xian)(xian)(xian)(xian)，零(ling)線(xian)(xian)(xian)(xian)]的(de)(de)(de)(de)(de)帶動(dong)負(fu)載的(de)(de)(de)(de)(de)性質不過PEN通常是(shi)(shi)為了節(jie)省材料以(yi)及在(zai)特殊地方(fang)應(ying)用(yong)(yong)的(de)(de)(de)(de)(de)，按照電(dian)(dian)力線(xian)(xian)(xian)(xian)路部署(shu)的(de)(de)(de)(de)(de)有(you)關標準，應(ying)當(dang)最(zui)(zui)(zui)大(da)可(ke)能(neng)的(de)(de)(de)(de)(de)使用(yong)(yong)PE+N線(xian)(xian)(xian)(xian)系統，即部署(shu)完全獨立的(de)(de)(de)(de)(de)PE保(bao)(bao)護(hu)(hu)(hu)線(xian)(xian)(xian)(xian)，而不是(shi)(shi)PEN這種(zhong)將(jiang)N線(xian)(xian)(xian)(xian)和(he)PE線(xian)(xian)(xian)(xian)捆綁(bang)于(yu)一起的(de)(de)(de)(de)(de)。PEN系統一旦遇到接(jie)地問題，N線(xian)(xian)(xian)(xian)有(you)時候由于(yu)負(fu)載不均衡，是(shi)(shi)會帶電(dian)(dian)的(de)(de)(de)(de)(de)，就很容易造成人身傷害了。所以(yi)切記，如果(guo)可(ke)能(neng)，應(ying)當(dang)盡(jin)最(zui)(zui)(zui)大(da)能(neng)力部署(shu)獨立的(de)(de)(de)(de)(de)PE保(bao)(bao)護(hu)(hu)(hu)線(xian)(xian)(xian)(xian)，即使不部署(shu)PE保(bao)(bao)護(hu)(hu)(hu)也(ye)最(zui)(zui)(zui)好(hao)不要(yao)使用(yong)(yong)PEN，PEN線(xian)(xian)(xian)(xian)我個人認為，除非特定領域需要(yao)，否則僅(jin)僅(jin)是(shi)(shi)應(ying)付檢查的(de)(de)(de)(de)(de)東西，他(ta)甚(shen)至比不部署(shu)保(bao)(bao)護(hu)(hu)(hu)線(xian)(xian)(xian)(xian)還要(yao)危險

如何區分pe線

按(an)照(zhao)GB9089.2的規定(ding)：保護(hu)導體(ti)（PE導體(ti)）是(shi)為滿足某(mou)些需要，用來與下(xia)列任一部件作(zuo)電(dian)氣(qi)連接(jie)(jie)的導體(ti)：外(wai)露可(ke)導電(dian)部分(fen)、外(wai)界可(ke)導電(dian)部分(fen)、主接(jie)(jie)地(di)(di)端子、接(jie)(jie)地(di)(di)極、電(dian)源(yuan)接(jie)(jie)地(di)(di)點(dian)或(huo)人(ren)工接(jie)(jie)地(di)(di)點(dian)。中(zhong)性導體(ti)（N導體(ti)）是(shi)與系統中(zhong)性點(dian)連接(jie)(jie)并能(neng)(neng)起(qi)傳輸電(dian)能(neng)(neng)作(zuo)用的導體(ti)。可(ke)見，N線(xian)(xian)(xian)是(shi)中(zhong)性線(xian)(xian)(xian)，是(shi)工作(zuo)線(xian)(xian)(xian)，在單相系統中(zhong)又被稱為“零線(xian)(xian)(xian)”；沒(mei)有它(ta)，設備可(ke)能(neng)(neng)就不能(neng)(neng)正常工作(zuo)了。而PE線(xian)(xian)(xian)是(shi)和設備外(wai)殼(ke)相連接(jie)(jie)的地(di)(di)線(xian)(xian)(xian)，沒(mei)有它(ta)，設備可(ke)能(neng)(neng)能(neng)(neng)夠工作(zuo)，但外(wai)殼(ke)可(ke)能(neng)(neng)帶電(dian)；它(ta)可(ke)以防止觸電(dian)事故發(fa)生。在實際(ji)實用中(zhong)，人(ren)們(men)常常接(jie)(jie)成(cheng)“保護(hu)中(zhong)性導體(ti)”，即(ji)接(jie)(jie)成(cheng)PEN線(xian)(xian)(xian)，兼具PE線(xian)(xian)(xian)和N線(xian)(xian)(xian)的功能(neng)(neng)。

接地線pe的作用

接(jie)地線(xian)(xian)的(de)(de)作(zuo)用重大(da)，目的(de)(de)是(shi)因為一(yi)(yi)類(lei)(lei)結(jie)構的(de)(de)產(chan)(chan)(chan)品，是(shi)需要(yao)依賴接(jie)地線(xian)(xian)作(zuo)為一(yi)(yi)道安全保護。由于一(yi)(yi)類(lei)(lei)結(jie)構產(chan)(chan)(chan)品內部結(jie)構是(shi)的(de)(de)基本(ben)絕(jue)緣(yuan)結(jie)構，一(yi)(yi)旦基本(ben)絕(jue)緣(yuan)失效，危險電流將通(tong)過通(tong)過保護接(jie)地線(xian)(xian)導到地，而對人(ren)，財產(chan)(chan)(chan)起(qi)到保護作(zuo)用。所以它的(de)(de)符(fu)號標(biao)識，線(xian)(xian)的(de)(de)大(da)小，絕(jue)緣(yuan)皮的(de)(de)顏(yan)色(se)，接(jie)地線(xian)(xian)的(de)(de)阻抗，連接(jie)方式，在電工，安規領域，都(dou)有非常明確和(he)嚴格的(de)(de)要(yao)求及測試驗證方法。

接地線pe的分類

為了(le)(le)便于檢修，國(guo)家統一(yi)了(le)(le)電線(xian)(xian)(xian)的(de)顏色(se)和字母(mu)符號。三根相(xiang)線(xian)(xian)(xian)的(de)顏色(se)分別是黃(huang)、綠、紅(hong)，字母(mu)是A、B、C，單相(xiang)電火線(xian)(xian)(xian)用字母(mu)L表示(shi)。零線(xian)(xian)(xian)是藍色(se)，字母(mu)N。地(di)線(xian)(xian)(xian)是黃(huang)綠雙色(se)線(xian)(xian)(xian)，字母(mu)PE。單芯電纜(lan)一(yi)般都是黑(hei)色(se)的(de)，沒有顏色(se)之分。多芯電纜(lan)有些地(di)線(xian)(xian)(xian)也(ye)(ye)不是黃(huang)綠雙色(se)線(xian)(xian)(xian)，也(ye)(ye)是黑(hei)色(se)的(de)。
