封(feng)閉(bi)母(mu)(mu)線(xian)由(you)工廠成套(tao)生產(chan)，質量(liang)有保證，運(yun)行維護工作量(liang)小，施工安裝(zhuang)簡(jian)便。另外，密集型絕緣(yuan)母(mu)(mu)線(xian)槽(cao)(cao)外殼采(cai)用(yong)多點接地，銅(tong)陵(ling)母(mu)(mu)線(xian)槽(cao)(cao)，使外殼基本處于(yu)等電(dian)位接地方式，大(da)(da)為簡(jian)化結構，并避免人身觸電(dian)危(wei)險。直(zhi)流(liu)供(gong)電(dian)系(xi)(xi)統由(you)交流(liu)屏(ping)、整流(liu)屏(ping)、直(zhi)流(liu)屏(ping)組成。采(cai)用(yong)封(feng)閉(bi)式母(mu)(mu)線(xian)槽(cao)(cao)后，需對常規直(zhi)流(liu)供(gong)電(dian)系(xi)(xi)統進(jin)行調整，插接母(mu)(mu)線(xian)槽(cao)(cao)廠家，在交換機房安裝(zhuang)一架或兩架大(da)(da)容(rong)量(liang)直(zhi)流(liu)分屏(ping)，直(zhi)流(liu)分屏(ping)內設置(zhi)大(da)(da)回路輸出。

線間(jian)因為一(yi)定的(de)(de)(de)間(jian)隙，可(ke)以(yi)使(shi)導(dao)線的(de)(de)(de)溫度下降(jiang)，所以(yi)提(ti)高了過載能(neng)力。母(mu)(mu)線槽(cao)(cao)是(shi)銅(tong)排或鋁作為導(dao)電(dian)(dian)(dian)體的(de)(de)(de)，母(mu)(mu)線槽(cao)(cao)設(she)備，使(shi)得電(dian)(dian)(dian)流容量減少了磁振蕩(dang)的(de)(de)(de)噪(zao)聲。母(mu)(mu)線槽(cao)(cao)的(de)(de)(de)連(lian)接(jie)插接(jie)式(shi)母(mu)(mu)線槽(cao)(cao)的(de)(de)(de)連(lian)接(jie)。母(mu)(mu)排的(de)(de)(de)連(lian)接(jie)，用其有(you)高絕(jue)(jue)緣(yuan)、耐(nai)一(yi)電(dian)(dian)(dian)弧(hu)、阻燃的(de)(de)(de)高強度絕(jue)(jue)緣(yuan)板做連(lian)接(jie)附件，用帶有(you)絕(jue)(jue)緣(yuan)套管的(de)(de)(de)螺栓緊固。母(mu)(mu)線槽(cao)(cao)是(shi)一(yi)種輸電(dian)(dian)(dian)設(she)備，就好似電(dian)(dian)(dian)纜一(yi)樣，是(shi)輸電(dian)(dian)(dian)用的(de)(de)(de)！并可(ke)做樹(shu)干(gan)分叉式(shi)送電(dian)(dian)(dian)，母(mu)(mu)線槽(cao)(cao) 母(mu)(mu)線，在線路中設(she)置多(duo)個饋(kui)電(dian)(dian)(dian)點，用于直接(jie)取電(dian)(dian)(dian)使(shi)用。

使(shi)用(yong)“Y”型防水性(xing)接頭，連(lian)接可靠(kao)方(fang)便(bian)。母線(xian)槽(cao)外(wai)殼采用(yong)冷壓成(cheng)型的軌道鋁合金(jin)型材，裝配簡單快捷(jie)，外(wai)形美觀(guan)。根據耐火極限(xian)的不(bu)(bu)(bu)同，其隔(ge)熱(re)(re)層采取的措施亦不(bu)(bu)(bu)同，若母線(xian)需作長時間通(tong)電運行(xing)，則(ze)其隔(ge)熱(re)(re)層一(yi)般直接利用(yong)空氣隔(ge)熱(re)(re)，以免影響云母運行(xing)過程中(zhong)熱(re)(re)量的散發(fa)。不(bu)(bu)(bu)要(yao)過多堆砌(qi)。不(bu)(bu)(bu)要(yao)為(wei)了節省空間，使(shi)用(yong)隔(ge)離措施就(jiu)沒(mei)有限(xian)度(du)的堆砌(qi)存儲，這樣做的后果對使(shi)用(yong)性(xing)能(neng)及構造(zao)(zao)造(zao)(zao)成(cheng)一(yi)些損(sun)壞(huai)，浪費資源。
