　　密(mi)集(ji)絕緣插接(jie)母線槽(cao)

　　其防(fang)潮(chao)(chao)、散(san)熱(re)效果較差。在防(fang)潮(chao)(chao)方(fang)(fang)面，母(mu)(mu)線(xian)(xian)(xian)(xian)在施工時(shi)，容易受潮(chao)(chao)及滲水，造(zao)(zao)成(cheng)相間絕緣電(dian)(dian)阻下降(jiang)。母(mu)(mu)線(xian)(xian)(xian)(xian)的(de)散(san)熱(re)主要靠外殼，由于線(xian)(xian)(xian)(xian)與線(xian)(xian)(xian)(xian)之間緊湊排列安(an)裝(zhuang)，L2、L3相熱(re)能(neng)散(san)發緩慢，形成(cheng)母(mu)(mu)線(xian)(xian)(xian)(xian)槽溫升(sheng)偏高。密集絕緣插(cha)接(jie)母(mu)(mu)線(xian)(xian)(xian)(xian)槽受外殼板材限制，只能(neng)生產(chan)不大(da)于3m的(de)水平段。由于母(mu)(mu)線(xian)(xian)(xian)(xian)相間氣隙小(xiao)，母(mu)(mu)線(xian)(xian)(xian)(xian)通過大(da)電(dian)(dian)流(liu)時(shi)，產(chan)生強大(da)的(de)電(dian)(dian)動力，使磁振(zhen)蕩頻(pin)率形成(cheng)疊加狀態，造(zao)(zao)成(cheng)過大(da)的(de)噪聲。插(cha)接(jie)式母(mu)(mu)線(xian)(xian)(xian)(xian)槽屬樹干式系統，具有體積小(xiao)、結構緊湊、運行可(ke)靠、傳輸電(dian)(dian)流(liu)大(da)、便(bian)于分接(jie)饋電(dian)(dian)、維護(hu)方(fang)(fang)便(bian)、能(neng)耗(hao)小(xiao)、動熱(re)穩(wen)定(ding)性好等優(you)點，在高層建筑中得到廣泛應用。
