密集母(mu)線(xian)槽可為交流(liu)三相(xiang)三線(xian)、三相(xiang)四線(xian)和(he)三相(xiang)五線(xian)制(zhi)，頻率為50-60Hz，電(dian)(dian)壓(ya)至400V，額定工(gong)作(zuo)電(dian)(dian)流(liu)為250~5000A，主要用作(zuo)工(gong)礦、企事(shi)業(ye)和(he)高層建筑(zhu)中新型的(de)供配(pei)電(dian)(dian)設(she)備。帶插口的(de)母(mu)線(xian)槽，可通過插接(jie)頭箱或(huo)開關(guan)箱，便能方便地(di)引出電(dian)(dian)源分(fen)路。由于母(mu)線(xian)槽具備體積小、結構緊(jin)湊(cou)、傳輸電(dian)(dian)流(liu)大、維護(hu)方便等優(you)點，成(cheng)了市場“搶手貨(huo)”。它的(de)安裝可直(zhi)接(jie)從變壓(ya)器接(jie)到低壓(ya)配(pei)電(dian)(dian)柜，也可從低壓(ya)柜直(zhi)接(jie)接(jie)到配(pei)電(dian)(dian)系統(tong)作(zuo)為配(pei)電(dian)(dian)干線(xian)線(xian)路。

因(yin)此兩段母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)主母(mu)(mu)(mu)(mu)(mu)排連(lian)接時，兩段母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)軸線(xian)(xian)(xian)要(yao)(yao)嚴格保持在一條中心線(xian)(xian)(xian)上(shang)，并使(shi)兩段母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)的(de)(de)母(mu)(mu)(mu)(mu)(mu)排及絕(jue)緣(yuan)板的(de)(de)螺(luo)(luo)栓(shuan)孔完全對齊(qi)，穿上(shang)螺(luo)(luo)栓(shuan)上(shang)緊時，池州密(mi)集型母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)，每(mei)個螺(luo)(luo)栓(shuan)要(yao)(yao)依次用力均(jun)勻。按(an)規(gui)范要(yao)(yao)求，為(wei)滿足母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)的(de)(de)搭接面積，螺(luo)(luo)栓(shuan)孔與(yu)螺(luo)(luo)栓(shuan)之問(wen)縫隙較小，由于毋線(xian)(xian)(xian)槽(cao)(cao)螺(luo)(luo)栓(shuan)增加了(le)絕(jue)緣(yuan)套(tao)管，使(shi)縫隙更為(wei)狹(xia)窄(zhai)。防水(shui)型母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)采用合理的(de)(de)“三明治”相線(xian)(xian)(xian)緊密(mi)疊壓(ya)結(jie)構設(she)計，使(shi)母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)外形更加緊湊(cou)，密(mi)集型母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)費用，體積更小，密(mi)集型母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)訂制廠家，并增加了(le)母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)系(xi)統(tong)的(de)(de)動熱穩定性，使(shi)母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)具(ju)有(you)阻抗低，密(mi)集型母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)與(yu)封閉式(shi)母(mu)(mu)(mu)(mu)(mu)線(xian)(xian)(xian)槽(cao)(cao)，電壓(ya)降低的(de)(de)優(you)點。

在使(shi)用(yong)封(feng)(feng)(feng)閉式(shi)(shi)(shi)母(mu)線(xian)槽的(de)過程中，應(ying)該注意哪些事項？下面就(jiu)讓我們為大家分析一下：在設(she)(she)計選型時應(ying)根據系(xi)統的(de)短路電流(liu)值及樣本(ben)上的(de)參數對所選定型號進(jin)行動穩(wen)定和(he)熱(re)穩(wen)定校驗（計算）。主要(yao)原(yuan)因是封(feng)(feng)(feng)閉式(shi)(shi)(shi)母(mu)線(xian)槽的(de)各連接部(bu)位(wei)的(de)連接方式(shi)(shi)(shi)還不(bu)能滿足防爆要(yao)求。封(feng)(feng)(feng)閉式(shi)(shi)(shi)母(mu)線(xian)槽造價較高(gao)，對于某些負(fu)荷集(ji)中或(huo)需要(yao)單獨供電設(she)(she)備的(de)場(chang)合(he)使(shi)用(yong)封(feng)(feng)(feng)閉式(shi)(shi)(shi)母(mu)線(xian)槽，從工(gong)程建設(she)(she)的(de)經(jing)濟性考慮，尚欠合(he)理(li)。
