通常耐(nai)(nai)火(huo)(huo)母線(xian)槽(cao)的(de)耐(nai)(nai)火(huo)(huo)時(shi)間(jian)分別為60分鐘,90分鐘,120分鐘和180分鐘。溫度達(da)到(dao)920?1050℃時(shi)熄(xi)滅,滿負(fu)荷(he)運轉8小時(shi)。 耐(nai)(nai)火(huo)(huo)母線(xian)槽(cao)的(de)技術要求: 耐(nai)(nai)火(huo)(huo)母線(xian)槽(cao)外殼采用耐(nai)(nai)高溫不低(di)于(yu)1100℃的(de)防火(huo)(huo)材(cai)料, 隔熱層采用耐(nai)(nai)高溫不低(di)于(yu)300℃的(de)絕緣材(cai)料, 滿負(fu)荷(he)運行可達(da)8h以上, 有國家(jia)認可的(de)檢(jian)測機構出(chu)具型式檢(jian)驗(yan)報告(gao)。 防火(huo)(huo)母線(xian)槽(cao)和耐(nai)(nai)火(huo)(huo)母線(xian)槽(cao)有什么區別 1、
NHJX耐(nai)火密(mi)集(ji)母線(xian)(xian)槽(cao)適用(yong)于額(e)定(ding)電(dian)壓690V以下,額(e)定(ding)工(gong)作(zuo)電(dian)流250~5000A,頻(pin)率50~60HZ的(de)輸配(pei)電(dian)系(xi)統(tong)。經過多年的(de)試(shi)驗和(he)工(gong)業(ye)通電(dian)運行,其電(dian)氣(qi)性(xing)、耐(nai)火性(xing)、金屬結(jie)(jie)構(gou)性(xing)均達到國內先(xian)進(jin)水平。 NHJX耐(nai)火密(mi)集(ji)母線(xian)(xian)槽(cao)結(jie)(jie)構(gou)性(xing)能 1、采用(yong)合理(li)的(de)“三明治”相線(xian)(xian)緊(jin)密(mi)疊壓結(jie)(jie)構(gou)設計(ji),母線(xian)(xian)槽(cao)外(wai)(wai)形緊(jin)湊、體(ti)積小,母線(xian)(xian)系(xi)統(tong)具(ju)有阻抗低、電(dian)壓降低、動(dong)熱穩(wen)定(ding)性(xing)好(hao)的(de)優點。 2、外(wai)(wai)殼采用(yong)冷拉成(cheng)型(xing)薄鋼型(xing)材混
母(mu)線(xian)槽(cao)短路強度: 密(mi)集型母(mu)線(xian)槽(cao)在(zai)(zai)電(dian)路中使(shi)用(yong)的(de)(de)(de)(de)過程中,如(ru)果有(you)短路的(de)(de)(de)(de)情況,它(ta)(ta)(ta)的(de)(de)(de)(de)短路負載能力也(ye)是很(hen)(hen)強。 它(ta)(ta)(ta)在(zai)(zai)選(xuan)擇使(shi)用(yong)的(de)(de)(de)(de)過程中,你(ni)可以放心的(de)(de)(de)(de)使(shi)用(yong),因為它(ta)(ta)(ta)的(de)(de)(de)(de)安全性能很(hen)(hen)高(gao),而且它(ta)(ta)(ta)的(de)(de)(de)(de)使(shi)用(yong)的(de)(de)(de)(de)壽(shou)命也(ye)是相(xiang)當的(de)(de)(de)(de)長,不需要你(ni)為它(ta)(ta)(ta)的(de)(de)(de)(de)質(zhi)量太過于但心。 密(mi)集型母(mu)線(xian)槽(cao)具有(you)很(hen)(hen)好(hao)的(de)(de)(de)(de)應變能力,如(ru)它(ta)(ta)(ta)在(zai)(zai)配電(dian)系統的(de)(de)(de)(de)設備中可以增加(jia)或變更隨意自如(ru)。 它(ta)(ta)(ta)的(de)(de)(de)(de)外形尺寸小,占地面積(ji)也(ye)小,用(yong)來裝修是很(hen)(hen)好(hao)看的(de)(de)(de)(de),就有(you)美感,為我們的(de)(de)(de)(de)
1、若密集型(xing)母(mu)線(xian)槽(cao)(cao)(cao)在生產的(de)(de)時候使用價(jia)格低(di)廉質(zhi)量不過(guo)關的(de)(de)絕(jue)緣(yuan)材料,切絕(jue)緣(yuan)材料有針孔(kong)、厚(hou)薄不均勻,就會(hui)導(dao)(dao)致(zhi)(zhi)母(mu)線(xian)槽(cao)(cao)(cao)在使用中出現故障。 2、若密集型(xing)母(mu)線(xian)槽(cao)(cao)(cao)的(de)(de)銅排含(han)有雜(za)質(zhi),且有有凸痕、毛(mao)刺、焊(han)接錯口等就會(hui)導(dao)(dao)致(zhi)(zhi)母(mu)線(xian)槽(cao)(cao)(cao)的(de)(de)投(tou)入運行一(yi)段時間后毛(mao)刺頂破絕(jue)緣(yuan)層,這就會(hui)導(dao)(dao)致(zhi)(zhi)母(mu)線(xian)槽(cao)(cao)(cao)短路(lu)的(de)(de)發生。 3、耐火母(mu)線(xian)槽(cao)(cao)(cao)應有噴(pen)水功(gong)能。若耐火母(mu)線(xian)槽(cao)(cao)(cao)無(wu)噴(pen)水功(gong)能,母(mu)線(xian)槽(cao)(cao)(cao)在消防(fang)噴(pen)水或(huo)在其(qi)他遇(yu)到水的(de)(de)情況下會(hui)導(dao)(dao)致(zhi)(zhi)母(mu)線(xian)槽(cao)(cao)(cao)短
密集型(xing)母線槽是具有系列配(pei)套、商(shang)品性(xing)生產、體積小、容量大(da)、設計施(shi)工(gong)周期短、裝拆方便、不會燃燒、安(an)全可靠、使用壽命長。線槽是用銅排或(huo)鋁作為導(dao)電(dian)(dian)(dian)體,電(dian)(dian)(dian)流容量很大(da)而(er)且電(dian)(dian)(dian)氣和機械(xie)性(xing)能好(hao),另外(wai)用金(jin)屬槽作為外(wai)殼,所以具有不燃燒,安(an)全可靠性(xing)高(gao),且使用壽命長,與傳(chuan)統的(de)配(pei)電(dian)(dian)(dian)或(huo)比(bi)較(jiao),設備所占面積顯著減少,并且外(wai)觀美觀,對于大(da)型(xing)建筑物的(de)施(shi)工(gong)和配(pei)電(dian)(dian)(dian)非常有利。
密集絕(jue)(jue)(jue)緣插接母(mu)(mu)線(xian)(xian)槽(cao) 其防潮(chao)、散熱效果較(jiao)差。在防潮(chao)方面,母(mu)(mu)線(xian)(xian)在施(shi)工(gong)時,容易(yi)受潮(chao)及滲水(shui),造成(cheng)(cheng)相間(jian)絕(jue)(jue)(jue)緣電阻下降。母(mu)(mu)線(xian)(xian)的散熱主要靠外(wai)殼,由于(yu)線(xian)(xian)與線(xian)(xian)之間(jian)緊湊排列安裝,L2、L3相熱能(neng)散發(fa)緩慢,形成(cheng)(cheng)母(mu)(mu)線(xian)(xian)槽(cao)溫升偏高。密集絕(jue)(jue)(jue)緣插接母(mu)(mu)線(xian)(xian)槽(cao)受外(wai)殼板(ban)材限制,只能(neng)生(sheng)產不(bu)大于(yu)3m的水(shui)平段。由于(yu)母(mu)(mu)線(xian)(xian)相間(jian)氣(qi)隙小,母(mu)(mu)線(xian)(xian)通過大電流(liu)時,產生(sheng)強(qiang)大的電動力,使磁振蕩頻率形成(cheng)(cheng)疊加狀(zhuang)態,造成(cheng)(cheng)過大的噪聲。插接式(shi)母(mu)(mu)線(xian)(xian)槽(cao)屬樹干(gan)式(shi)系(xi)統,具
高(gao)壓(ya)(ya)母(mu)線(xian)(xian)和(he)低(di)壓(ya)(ya)母(mu)線(xian)(xian),這兩(liang)者母(mu)線(xian)(xian)材(cai)質(zhi)(zhi)無區別,安裝工藝不(bu)同(tong)(tong)。由于(yu)(yu)電(dian)壓(ya)(ya)等(deng)級(ji)不(bu)同(tong)(tong),要求的(de)(de)絕緣子不(bu)同(tong)(tong),母(mu)線(xian)(xian)間距不(bu)同(tong)(tong)。 高(gao)壓(ya)(ya)母(mu)線(xian)(xian)槽(cao)和(he)低(di)壓(ya)(ya)母(mu)線(xian)(xian)槽(cao)區別: 1、材(cai)質(zhi)(zhi)區別 高(gao)壓(ya)(ya)母(mu)線(xian)(xian)槽(cao)外殼(ke)是(shi)封閉的(de)(de),可以大(da)大(da)減少停(ting)電(dian)檢修次數。 低(di)壓(ya)(ya)母(mu)線(xian)(xian)就是(shi)硬鋁母(mu)線(xian)(xian)排,是(shi)電(dian)力配(pei)電(dian)設備上的(de)(de)導(dao)電(dian)材(cai)料。 2、應用(yong)(yong)區別 高(gao)壓(ya)(ya)母(mu)線(xian)(xian)槽(cao)運用(yong)(yong)于(yu)(yu)大(da)型變電(dian)站、大(da)型企業的(de)(de)自備電(dian)廠(chang)中(zhong)。 低(di)壓(ya)(ya)母(mu)線(xian)(xian)一般用(yong)(yong)于(yu)(yu)室內變壓(ya)(ya)器到配(pei)
高(gao)(gao)壓(ya)母線(xian)(xian)(xian)槽送(song)電前(qian),應驗(yan)電、放電,并用接地棒將(jiang)相(xiang)間短路和可靠(kao)接地后方可進行操作。 高(gao)(gao)壓(ya)母線(xian)(xian)(xian)槽送(song)電前(qian)驗(yan)電方法(fa): 高(gao)(gao)壓(ya)母線(xian)(xian)(xian)槽受電時,不(bu)帶有(you)負載(zai)的所有(you)母線(xian)(xian)(xian)饋電裝置(zhi)均應處于“分斷狀態,受電后,必(bi)須測量每只分線(xian)(xian)(xian)箱,保證(zheng)輸(shu)入電壓(ya)正(zheng)常穩(wen)定,不(bu)缺相(xiang)。 1、必(bi)須驗(yan)證(zheng)母線(xian)(xian)(xian)槽干線(xian)(xian)(xian)相(xiang)序(xu)正(zheng)確,母線(xian)(xian)(xian)槽絕(jue)緣電阻不(bu)低于20M 2、保證(zheng)母線(xian)(xian)(xian)槽干線(xian)(xian)(xian)不(bu)受液體、固體的侵入 3、必(bi)須確認安裝支架穩(wen)固,連接螺
高(gao)壓(ya)配電(dian)(dian)(dian)(dian)柜(ju)之間(jian)連(lian)(lian)接(jie)用(yong)母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao),電(dian)(dian)(dian)(dian)纜(lan)(lan)能不用(yong)就不用(yong),電(dian)(dian)(dian)(dian)纜(lan)(lan)動熱穩定性和絕緣(yuan)不如母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao),故障(zhang)率也相對的(de)高(gao),電(dian)(dian)(dian)(dian)纜(lan)(lan)造(zao)價(jia)低,連(lian)(lian)接(jie)靈(ling)活方(fang)便適合長(chang)距(ju)離(li)和不便使用(yong)母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)的(de)場合。 母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)安裝高(gao)壓(ya)柜(ju)方(fang)法(fa): 1: 可(ke)以裝在(zai)配電(dian)(dian)(dian)(dian)箱后(hou)面的(de)。插接(jie)箱只是(shi)負(fu)責從母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)中(zhong)引(yin)點到需要處,插接(jie)箱內有(you)開關的(de),同時插接(jie)箱一(yi)頭插在(zai)母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)內,一(yi)頭連(lian)(lian)接(jie)的(de)是(shi)電(dian)(dian)(dian)(dian)纜(lan)(lan),再通過電(dian)(dian)(dian)(dian)纜(lan)(lan)到樓層配電(dian)(dian)(dian)(dian)箱。 2: 母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)槽(cao)(cao)應該是(shi)中(zhong)間(jian)連(lian)(lian)接(jie)單元(yuan),在(zai)母(mu)(mu)(mu)線(xian)(xian)(xian)(xian)(xian)
密(mi)集型母線(xian)(xian)槽散(san)熱設計: 1、密(mi)集型母線(xian)(xian)槽相(xiang)與(yu)相(xiang)及(ji)相(xiang)與(yu)外殼均緊貼(tie)在一起,故能承受(shou)較大(da)的電動應力和(he)熱應力。并能將導電排所產(chan)生的熱量迅速散(san)發,載(zai)流量大(da)。 2、接(jie)(jie)頭用絕緣螺栓緊固,同(tong)時采用雙(shuang)連接(jie)(jie)銅排連接(jie)(jie),有效增加(jia)了(le)(le)接(jie)(jie)頭接(jie)(jie)觸面積,大(da)大(da)降(jiang)低了(le)(le)接(jie)(jie)頭部(bu)位(wei)溫升(sheng)。
一(yi)般情(qing)況下,插接母(mu)線槽(cao)的價格包括安裝費,以米(mi)(mi)計算。因為(wei)工作量(liang)太小,電(dian)工一(yi)般是按天算的。不同(tong)(tong)地區收(shou)費不同(tong)(tong),所以收(shou)費也不同(tong)(tong),從300到500不等。 銅(tong)母(mu)線槽(cao)多少錢一(yi)米(mi)(mi)合適(shi) 銅(tong)母(mu)線槽(cao)價格大(da)概在700左右(you),密(mi)集型母(mu)線槽(cao)適(shi)用(yong)于交流三(san)相(xiang)四(si)線、三(san)相(xiang)五線制,頻50~60Hz,額定(ding)電(dian)壓至(zhi)690V,額定(ding)工作電(dian)流250~5000A的供配(pei)電(dian)系統,作為(wei)工礦(kuang)、企(qi)事業和(he)高層建(jian)筑中供配(pei)電(dian)設備的輔助(zhu)設備,特別適(shi)用(yong)于
