style="text-indent:25px">母線的特征：性能方面。母線采用銅排或者鋁排，其電流密度大，電阻小，集膚效應(yīng)小，無須降容使用。電壓降小也就意味著能量損耗小，較終節(jié)約用戶的投資。而對(duì)于電纜來講，由于電纜芯是多股細(xì)銅線，其根面積較同電流等級(jí)的母線要大。并且其“集膚效應(yīng)”嚴(yán)重，減少了電流額定值，增加了電壓降，容易發(fā)熱。線路的能量損失大，容易老化。安全性。母線槽的金屬封閉外殼能夠保護(hù)母線免受機(jī)械損傷或動(dòng)物傷害，在配電系統(tǒng)中采用插入單元的安裝很安全，外殼可以作為整體接地，接地非常的可靠，而電纜的PVC外殼易受機(jī)械和動(dòng)物損傷，安裝電纜時(shí)必須先切斷電源，如果有錯(cuò)誤發(fā)生會(huì)很危險(xiǎn)，特別是電纜要進(jìn)行現(xiàn)場(chǎng)接地工作，接地的不可靠導(dǎo)致危險(xiǎn)性增加。</p><p

style="text-indent:25px">常用母線，適用范圍母線分為硬母線和軟母線。硬母線按其形狀不同有可分為：矩形母線、管型母線、槽型母線、菱形母線等多種。矩形母線是常用的母線，也成母線排。按其材質(zhì)又有鋁母線（鋁排）和銅母線（銅排）之分。矩形母線的優(yōu)點(diǎn)是裝置便利，在運(yùn)轉(zhuǎn)中變化小，載流量大，但造價(jià)較高。管型母線通常和插銷刀閘合作運(yùn)用?，F(xiàn)在選用的多位鋼管母線，施工便利，但載流容量甚小。鋁管盡管載流容量大，但施工工藝難度較大，現(xiàn)在尚少選用。槽型和菱形母線均運(yùn)用在大電流的母線橋及對(duì)熱、動(dòng)安穩(wěn)要求較高的配電場(chǎng)合。軟母線多用于室外。室外空間大，導(dǎo)線距離寬，并且放熱作用好，施工便利，造價(jià)也較低。母線種類、適用范圍條件、母線體系以及配電柜母線核算。不論挑選何種母線均應(yīng)符合下述幾個(gè)條件：所選母線必須滿足持續(xù)作業(yè)電流的要求。關(guān)于全年平均負(fù)荷高、母線較長。輸電容量也較大的母線，應(yīng)按經(jīng)濟(jì)電流密度進(jìn)行挑選。母線應(yīng)按電暈電壓校驗(yàn)合格。關(guān)閉式母線和母線槽指的都是同一種東西。重慶低壓母線報(bào)價(jià)</p><p
