母(mu)(mu)線(xian)(xian)(xian)(xian)橋(qiao)和母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)的(de)區別，母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)有密集型絕緣(yuan)母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)和空氣絕緣(yuan)母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)之分，母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)也是用(yong)鋼板做成的(de)外殼把(ba)母(mu)(mu)排裝起(qi)來， 母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)結構相對(dui)母(mu)(mu)線(xian)(xian)(xian)(xian)橋(qiao)來說要復雜(za)點，高(gao)(gao)壓(ya)共箱(xiang)母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)廠(chang)家(jia)批發，母(mu)(mu)線(xian)(xian)(xian)(xian)橋(qiao)是為了銅排跨接(jie)(柜到(dao)柜，柜到(dao)墻)而簡單制作的(de)矩形(xing)支撐保護體(ti)(ti)，母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)也可以，但(dan)是母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)右(you)完善的(de)結構組成，體(ti)(ti)積小，內部有絕緣(yuan)附件，高(gao)(gao)壓(ya)共箱(xiang)母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)廠(chang)家(jia)，可以更(geng)長具(ju)體(ti)(ti)和多次轉向(xiang)和擴展，高(gao)(gao)壓(ya)共箱(xiang)母(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)價格，中(zhong)間還(huan)有變容(rong)，防火等單元，還(huan)而已配(pei)置(zhi)插接(jie)箱(xiang)提供連接(jie)點電源。

封(feng)閉式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)簡稱母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)。封(feng)閉式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)和(he)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)指的是同一個東西。封(feng)閉式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)是由金屬(shu)板（鋼(gang)板或鋁(lv)板）作為保(bao)護殼(ke)(ke)、導電條、絕緣(yuan)(yuan)(yuan)材料及相(xiang)關附(fu)件組成的母(mu)(mu)(mu)(mu)線(xian)系(xi)統。可制(zhi)成間(jian)隔插(cha)(cha)(cha)入(ru)(ru)式(shi)(shi)(shi)(shi)接線(xian)盒的插(cha)(cha)(cha)入(ru)(ru)式(shi)(shi)(shi)(shi)封(feng)閉母(mu)(mu)(mu)(mu)線(xian)，也可制(zhi)成中(zhong)間(jian)不帶(dai)接線(xian)盒的饋電式(shi)(shi)(shi)(shi)封(feng)閉母(mu)(mu)(mu)(mu)線(xian)。封(feng)閉式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)（母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)）按絕緣(yuan)(yuan)(yuan)方式(shi)(shi)(shi)(shi)可分(fen)為空(kong)氣(qi)插(cha)(cha)(cha)入(ru)(ru)式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)、密(mi)(mi)絕緣(yuan)(yuan)(yuan)插(cha)(cha)(cha)入(ru)(ru)式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)和(he)高(gao)強(qiang)度插(cha)(cha)(cha)入(ru)(ru)式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)三種(zhong)。按其結(jie)構和(he)用途分(fen)為致密(mi)(mi)絕緣(yuan)(yuan)(yuan)、空(kong)氣(qi)絕緣(yuan)(yuan)(yuan)、空(kong)氣(qi)附(fu)加絕緣(yuan)(yuan)(yuan)、耐火(huo)、樹脂絕緣(yuan)(yuan)(yuan)和(he)滑(hua)觸式(shi)(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)；按外殼(ke)(ke)材料分(fen)為鋼(gang)殼(ke)(ke)、鋁(lv)合(he)金殼(ke)(ke)和(he)鋼(gang)鋁(lv)混合(he)殼(ke)(ke)母(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)。

復合絕緣型母線槽：

       母線(xian)(xian)(xian)槽除了導電(dian)排本身(shen)具有絕(jue)(jue)緣層外，各相線(xian)(xian)(xian)之間(jian)還有一定的空氣介質絕(jue)(jue)緣。在各種(zhong)彎頭采(cai)(cai)用硫化(hua)絕(jue)(jue)緣技術(shu)。直線(xian)(xian)(xian)段(duan)采(cai)(cai)用MT-7-3橡膠套管(guan)。硫化(hua)絕(jue)(jue)緣技術(shu)：材(cai)料為(wei)CZ260快固(gu)絕(jue)(jue)緣粉(fen)末(mo)，高壓共箱(xiang)母線(xian)(xian)(xian)槽，采(cai)(cai)用四元交聯(lian)固(gu)化(hua)，絕(jue)(jue)緣層與導電(dian)排間(jian)無間(jian)隙。其(qi)散(san)熱(re)性能(neng)、防(fang)潮性能(neng)、絕(jue)(jue)緣可靠(kao)性能(neng)均優。

母(mu)線完全(quan)差(cha)動(dong)保(bao)護的(de)(de)(de)優點：1、各組成元件(jian)和(he)接線比較(jiao)簡單，調試方便，運行人員易(yi)于(yu)掌握。2、采用速飽(bao)和(he)變流器(qi)可以較(jiao)有(you)效(xiao)地防止由于(yu)區外故障一次電(dian)(dian)流中的(de)(de)(de)直流分量導致電(dian)(dian)流互感器(qi)飽(bao)和(he)引起的(de)(de)(de)保(bao)護誤動(dong)作。3、當元件(jian)固定連接時母(mu)線差(cha)動(dong)保(bao)護有(you)很好的(de)(de)(de)選(xuan)擇(ze)性。4、當母(mu)聯斷(duan)路器(qi)斷(duan)開時母(mu)線差(cha)動(dong)保(bao)護仍有(you)選(xuan)擇(ze)能力;在兩條母(mu)線先后發生(sheng)短路時母(mu)線差(cha)動(dong)保(bao)護仍能可靠(kao)地動(dong)作。
