　　密(mi)集絕緣插接母線槽

　　其防潮、散(san)(san)熱效果(guo)較(jiao)差。在(zai)防潮方面(mian)，母(mu)(mu)(mu)線(xian)(xian)在(zai)施工時，容(rong)易受潮及滲水(shui)，造成相間絕緣電(dian)(dian)阻下(xia)降。母(mu)(mu)(mu)線(xian)(xian)的散(san)(san)熱主(zhu)要(yao)靠(kao)(kao)外殼，由于(yu)線(xian)(xian)與線(xian)(xian)之間緊(jin)湊排列安裝，L2、L3相熱能散(san)(san)發緩慢(man)，形(xing)成母(mu)(mu)(mu)線(xian)(xian)槽溫升偏高(gao)。密集絕緣插(cha)接母(mu)(mu)(mu)線(xian)(xian)槽受外殼板材限制，只能生產不(bu)大(da)(da)(da)于(yu)3m的水(shui)平段。由于(yu)母(mu)(mu)(mu)線(xian)(xian)相間氣(qi)隙小(xiao)，母(mu)(mu)(mu)線(xian)(xian)通過(guo)(guo)大(da)(da)(da)電(dian)(dian)流時，產生強大(da)(da)(da)的電(dian)(dian)動力，使磁振蕩(dang)頻(pin)率形(xing)成疊(die)加狀態(tai)，造成過(guo)(guo)大(da)(da)(da)的噪聲。插(cha)接式(shi)母(mu)(mu)(mu)線(xian)(xian)槽屬樹干式(shi)系統，具有(you)體積小(xiao)、結構緊(jin)湊、運行(xing)可靠(kao)(kao)、傳輸電(dian)(dian)流大(da)(da)(da)、便于(yu)分接饋電(dian)(dian)、維護方便、能耗(hao)小(xiao)、動熱穩定性好等優點，在(zai)高(gao)層(ceng)建(jian)筑中(zhong)得到(dao)廣泛應(ying)用。
