低壓母(mu)(mu)(mu)線槽(cao)分空(kong)(kong)氣(qi)式(shi)與密集(ji)式(shi)，空(kong)(kong)氣(qi)式(shi)基本淘汰(tai)了(le)，它的(de)(de)(de)缺點(dian)非(fei)常明顯(xian)，空(kong)(kong)氣(qi)型(xing)銅排母(mu)(mu)(mu)線槽(cao)公司，主要缺點(dian)是(shi)：體積大(da)(da)且散(san)熱(re)(re)不(bu)(bu)良，因(yin)(yin)強度問題，外殼不(bu)(bu)能(neng)夠(gou)(gou)采用防銹(xiu)而(er)且美觀(guan)的(de)(de)(de)鋁合(he)金(jin)。可能(neng)有(you)人(ren)誤認(ren)為，空(kong)(kong)氣(qi)型(xing)銅排母(mu)(mu)(mu)線槽(cao)生(sheng)產廠(chang)家，空(kong)(kong)氣(qi)式(shi)比密集(ji)式(shi)散(san)熱(re)(re)更好，理由是(shi)空(kong)(kong)氣(qi)流(liu)通有(you)利散(san)熱(re)(re)，事實情況并非(fei)如此(ci)。散(san)熱(re)(re)三(san)要素是(shi)：對流(liu)，輻(fu)射及傳(chuan)導，空(kong)(kong)氣(qi)式(shi)母(mu)(mu)(mu)線槽(cao)之所以散(san)熱(re)(re)不(bu)(bu)良，是(shi)因(yin)(yin)為兩(liang)端是(shi)封(feng)閉(bi)的(de)(de)(de)，每節(jie)之間又有(you)絕緣支架隔開的(de)(de)(de)，因(yin)(yin)此(ci)空(kong)(kong)氣(qi)在(zai)(zai)母(mu)(mu)(mu)線槽(cao)內部不(bu)(bu)能(neng)夠(gou)(gou)流(liu)通，空(kong)(kong)氣(qi)不(bu)(bu)是(shi)良好的(de)(de)(de)熱(re)(re)傳(chuan)導介質，從(cong)而(er)造(zao)成對流(liu)與傳(chuan)導散(san)熱(re)(re)不(bu)(bu)良。空(kong)(kong)氣(qi)式(shi)母(mu)(mu)(mu)線槽(cao)由于體積大(da)(da)，額定(ding)電流(liu)一般(ban)不(bu)(bu)超(chao)過 1000A。空(kong)(kong)氣(qi)式(shi)母(mu)(mu)(mu)線槽(cao)由于相間距離大(da)(da)，在(zai)(zai)靠(kao)近母(mu)(mu)(mu)線槽(cao)鋼板外殼處，渦(wo)流(liu)嚴(yan)重(zhong)，尤其是(shi)大(da)(da)容量母(mu)(mu)(mu)線槽(cao)，渦(wo)流(liu)損耗更嚴(yan)重(zhong)

外(wai)殼在(zai)(zai)多處接地，以確保(bao)人(ren)員(yuan)及(ji)時(shi)安全(quan)。由(you)于殼體(ti)渦流(liu)和(he)循環(huan)(huan)電(dian)流(liu)的(de)(de)(de)屏(ping)蔽(bi)好(hao)處，殼體(ti)中的(de)(de)(de)磁場大(da)(da)(da)大(da)(da)(da)減弱。當(dang)(dang)發(fa)生(sheng)外(wai)部短路時(shi)，母線(xian)(xian)之(zhi)間的(de)(de)(de)電(dian)動勢會(hui)大(da)(da)(da)大(da)(da)(da)低垂(chui)；當(dang)(dang)電(dian)流(liu)通過母線(xian)(xian)時(shi)，外(wai)殼會(hui)感應(ying)。循環(huan)(huan)電(dian)流(liu)還會(hui)屏(ping)蔽(bi)外(wai)殼外(wai)部的(de)(de)(de)磁場，并處置(zhi)附近鋼(gang)結構(gou)的(de)(de)(de)發(fa)熱問題。外(wai)殼可(ke)用作強制冷(leng)卻的(de)(de)(de)通道，從而前進了總線(xian)(xian)的(de)(de)(de)載流(liu)量。設備護(hu)衛工(gong)作量小。但是(shi)，存(cun)在(zai)(zai)少(shao)少(shao)缺點，主要是(shi)：由(you)于存(cun)在(zai)(zai)循環(huan)(huan)電(dian)流(liu)和(he)渦流(liu)，殼會(hui)發(fa)生(sheng)花(hua)消(xiao)；有色金屬花(hua)消(xiao)量大(da)(da)(da)；母線(xian)(xian)的(de)(de)(de)散熱條(tiao)件差。憑證殼體(ti)的(de)(de)(de)電(dian)氣連(lian)接技巧，離關聯(lian)閉母線(xian)(xian)可(ke)分為分段絕(jue)緣，完全(quan)連(lian)接和(he)限流(liu)電(dian)抗(kang)器完全(quan)連(lian)接三種。

母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)將適用于各種(zhong)惡劣環(huan)境(jing)，目前市場上母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)主要有(you)單極母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)、多(duo)極母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)、剛(gang)體母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)、無接縫(feng)母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)等產(chan)(chan)品(pin)。這(zhe)些產(chan)(chan)品(pin)對于特別(bie)惡劣的環(huan)境(jing)，空(kong)氣(qi)型銅排母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)，很(hen)難(nan)適應，所以說，空(kong)氣(qi)型銅排母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)供應，以后的母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)企業(ye)會(hui)改進很(hen)多(duo)，將會(hui)讓母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)適應更多(duo)惡劣的自然壞境(jing)。母(mu)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)用于室內移動式電(dian)(dian)(dian)氣(qi)設備的供電(dian)(dian)(dian)，如各種(zhong)中(zhong)小型功能起重機、電(dian)(dian)(dian)葫蘆、電(dian)(dian)(dian)動工具和(he)娛樂設施等。
