1、護套：是一根(gen)(gen)半封閉的(de)導(dao)(dao)形管狀(zhuang)部(bu)件(jian)，芒市空(kong)氣型(xing)銅排母(mu)線(xian)槽(cao)，是滑觸(chu)線(xian)的(de)主(zhu)(zhu)體部(bu)分。其內部(bu)可(ke)根(gen)(gen)據需要(yao)嵌高3-16根(gen)(gen)祼體導(dao)(dao)軌作為供電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)線(xian)，各導(dao)(dao)軌間(jian)相互絕緣，從而(er)保(bao)供電(dian)(dian)(dian)(dian)(dian)的(de)安全性。并在帶電(dian)(dian)(dian)(dian)(dian)檢修時(shi)防檢修人員觸(chu)電(dian)(dian)(dian)(dian)(dian)事故。廠家生產的(de)導(dao)(dao)管每條長度各不相同，可(ke)以連(lian)接成任(ren)意需要(yao)長度，普(pu)通(tong)導(dao)(dao)管制(zhi)作成直線(xian)形，也可(ke)按需求制(zhi)成圓弧形等。 ? ? ?2、導(dao)(dao)體：主(zhu)(zhu)要(yao)材質是銅，根(gen)(gen)據其截(jie)面(mian)積常用(yong)的(de)有(you)(you)10平方，16平方，25平方。 ? ? ?3、受電(dian)(dian)(dian)(dian)(dian)器是在導(dao)(dao)管內運行(xing)的(de)一組電(dian)(dian)(dian)(dian)(dian)刷殼(ke)架，由安置在用(yong)電(dian)(dian)(dian)(dian)(dian)機構(gou)（行(xing)車、小車、電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)葫蘆等）上的(de)撥叉（或牽引鏈(lian)條等）帶動(dong)(dong)，使(shi)之(zhi)與用(yong)電(dian)(dian)(dian)(dian)(dian)機構(gou)同步運行(xing)，將通(tong)過導(dao)(dao)軌，空(kong)氣型(xing)銅排母(mu)線(xian)槽(cao)廠家，電(dian)(dian)(dian)(dian)(dian)刷的(de)電(dian)(dian)(dian)(dian)(dian)能輿(yu)到電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機或其他控制(zhi)元件(jian)。受電(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)刷的(de)極(ji)數有(you)(you)3-16極(ji)與導(dao)(dao)管中導(dao)(dao)軌極(ji)數相應。

由于環境溫度(du)過高或是(shi)(shi)(shi)提掛架(jia)間距大(da)或松(song)脫，導致導軌變形，集(ji)電(dian)器運行受阻。此時(shi)我們要采取(qu)的(de)應(ying)對(dui)方(fang)式就是(shi)(shi)(shi)局部采用隔熱(re)板，空氣型銅(tong)排母線(xian)槽(cao)報(bao)價(jia)，室外加遮(zhe)陽板；增加滑觸(chu)線(xian)提掛架(jia)數(shu)量(liang)，矯(jiao)正(zheng)導體(ti)(ti)并擰緊(jin)螺絲(si)。? ? 母線(xian)槽(cao)集(ji)電(dian)器行走有較(jiao)大(da)異響時(shi)，可能是(shi)(shi)(shi)因為電(dian)流過大(da)、接(jie)(jie)(jie)頭不平(ping)，一般的(de)應(ying)對(dui)方(fang)法是(shi)(shi)(shi)增加集(ji)電(dian)器數(shu)量(liang)或者重新(xin)調整導軌連接(jie)(jie)(jie)。? ? ? 導體(ti)(ti)內出現火花(hua)，主要原因是(shi)(shi)(shi)電(dian)刷表面與(yu)導軌接(jie)(jie)(jie)觸(chu)不良。處理(li)方(fang)法采取(qu)檢測導體(ti)(ti)接(jie)(jie)(jie)頭，適當磨合電(dian)刷，保６０％的(de)接(jie)(jie)(jie)觸(chu)面積。

在200MW及以(yi)上發(fa)電機(ji)引出(chu)線(xian)回路中(zhong)，采用(yong)分相封閉母(mu)線(xian)的(de)(de)(de)優點是：由(you)(you)于母(mu)線(xian)封閉在外(wai)殼(ke)內(nei)，不受環(huan)境和(he)污穢影響(xiang)，防止相間短(duan)路和(he)消除外(wai)界潮氣(qi)、灰塵引起的(de)(de)(de)接(jie)地(di)故障(zhang)，同時(shi)由(you)(you)于外(wai)殼(ke)多點接(jie)地(di)，保證人觸及時(shi)的(de)(de)(de)安全；由(you)(you)于外(wai)殼(ke)渦(wo)流(liu)(liu)(liu)和(he)環(huan)流(liu)(liu)(liu)的(de)(de)(de)屏(ping)蔽(bi)作(zuo)(zuo)用(yong)，使殼(ke)內(nei)的(de)(de)(de)磁場大為減弱，外(wai)部短(duan)路時(shi)，母(mu)線(xian)間的(de)(de)(de)電動力大大降低；當(dang)電流(liu)(liu)(liu)通(tong)過(guo)母(mu)線(xian)時(shi)，外(wai)殼(ke)感應(ying)出(chu)來的(de)(de)(de)環(huan)流(liu)(liu)(liu)也屏(ping)蔽(bi)了(le)殼(ke)外(wai)磁場，空氣(qi)型銅排母(mu)線(xian)槽單價，解決了(le)附近(jin)鋼構(gou)的(de)(de)(de)發(fa)熱問題(ti)；外(wai)殼(ke)可作(zuo)(zuo)為強制(zhi)冷(leng)卻(que)的(de)(de)(de)通(tong)道(dao)，提高了(le)母(mu)線(xian)的(de)(de)(de)載流(liu)(liu)(liu)量(liang)(liang)；安裝維護工(gong)作(zuo)(zuo)量(liang)(liang)小。不過(guo)也有些缺點，主要是：由(you)(you)于環(huan)流(liu)(liu)(liu)和(he)渦(wo)流(liu)(liu)(liu)的(de)(de)(de)存在，外(wai)殼(ke)將(jiang)產生損耗(hao)；有色金屬消耗(hao)量(liang)(liang)大；
