母(mu)線(xian)(xian)槽供(gong)電(dian)(dian)(dian)系統通常是主干線(xian)(xian)從(cong)配電(dian)(dian)(dian)中(zhong)心引出以散射狀靈活供(gong)電(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)纜(lan)供(gong)電(dian)(dian)(dian)則受分接難度大(da)、載流量小、難以分散控(kong)制等因(yin)素限制，彌勒共箱(xiang)型母(mu)線(xian)(xian)槽，通常是'點對(dui)點'供(gong)電(dian)(dian)(dian)，特別(bie)是在高(gao)層(ceng)建筑供(gong)電(dian)(dian)(dian)系統中(zhong)。

母線槽的(de)安裝(zhuang)確實需要(yao)的(de)安裝(zhuang)技術，但卻只需要(yao)按照(zhao)產品標準安裝(zhuang)程序即可(ke)，一次性完成(cheng)安裝(zhuang)。另外，母線槽結構緊湊，占(zhan)用空(kong)間相對較小，易(yi)于管道、線路空(kong)間布(bu)置，且安裝(zhuang)方便。

母線(xian)槽的(de)(de)維護(hu)比較簡單。母線(xian)槽日常維護(hu)時，共箱(xiang)型(xing)母線(xian)槽生產商，通常是測量(liang)外(wai)殼和穿芯螺栓的(de)(de)溫升(sheng)、進線(xian)箱(xiang)的(de)(de)接頭溫升(sheng)等(deng)，穿芯螺栓若采(cai)用4.8級則(ze)需要定期(qi)(qi)緊固(gu)，若采(cai)用8.8級的(de)(de)高強螺栓則(ze)不必(bi)定期(qi)(qi)堅固(gu)。

線槽執行GB 7251.6-2015，該標準適用(yong)于額定電(dian)(dian)(dian)壓交流不超(chao)過1000V，共箱型母線槽廠，直流不超(chao)過1500V的成(cheng)套設(she)(she)備；與發(fa)電(dian)(dian)(dian)、輸配電(dian)(dian)(dian)、電(dian)(dian)(dian)能(neng)轉換(huan)及控制電(dian)(dian)(dian)能(neng)損耗的設(she)(she)備配套使(shi)用(yong)的成(cheng)套設(she)(she)備；為特殊條(tiao)件設(she)(she)計(ji)(ji)的成(cheng)套設(she)(she)備；為機器的電(dian)(dian)(dian)氣設(she)(she)備而設(she)(she)計(ji)(ji)的成(cheng)套設(she)(she)備等(deng)。

封閉母線

封閉(bi)母線(xian)執行GB/T 8349-2000標準，該標準規(gui)定了金屬封閉(bi)母線(xian)的類型、技術參數、結構性能、試驗方法(fa)、設(she)計制造和包裝(zhuang)運輸(shu)(shu)方式、安(an)裝(zhuang)運行要(yao)求等。適用于35kV及以下(xia)、電(dian)流4000A及以下(xia)，50/60Hz的金屬封閉(bi)母線(xian)，主要(yao)用于發電(dian)機出線(xian)及其他輸(shu)(shu)配電(dian)回路，以安(an)全傳(chuan)輸(shu)(shu)電(dian)能。該標準明確指出不適用于母線(xian)槽。

按用途一趟母(mu)線(xian)(xian)槽一般由(you)始端母(mu)線(xian)(xian)槽、母(mu)線(xian)(xian)槽由(you)由(you)什(shen)么組(zu)(zu)成直(zhi)通(tong)母(mu)線(xian)(xian)槽（分(fen)帶插(cha)孔(kong)和不帶插(cha)孔(kong)兩(liang)種）、L型(xing)(xing)(xing)(xing)垂(chui)直(zhi)（水(shui)平(ping)）彎(wan)通(tong)母(mu)線(xian)(xian)、Z型(xing)(xing)(xing)(xing)垂(chui)直(zhi)（水(shui)平(ping)）偏置(zhi)母(mu)線(xian)(xian)、T型(xing)(xing)(xing)(xing)垂(chui)直(zhi)（水(shui)平(ping)）三(san)通(tong)母(mu)線(xian)(xian)、X型(xing)(xing)(xing)(xing)垂(chui)直(zhi)（水(shui)平(ping)）四通(tong)母(mu)線(xian)(xian)、母(mu)線(xian)(xian)槽由(you)由(you)什(shen)么組(zu)(zu)成變容(rong)母(mu)線(xian)(xian)、膨脹(zhang)母(mu)線(xian)(xian)、終(zhong)(zhong)端封頭、終(zhong)(zhong)端接線(xian)(xian)箱、槽由(you)由(you)什(shen)么組(zu)(zu)成配(pei)插(cha)接箱、母(mu)線(xian)(xian)有(you)關附件(jian)及(ji)緊固裝置(zhi)等組(zu)(zu)成。
