bjx51防爆接線箱安裝與維修方法

　電(dian)氣設備在使(shi)(shi)用(yong)(yong)(yong)(yong)中(zhong)須(xu)經(jing)電(dian)線(xian)(xian)(xian)或(huo)電(dian)纜(lan)與供電(dian)網絡連接(jie)(jie)(jie)起來，形(xing)成(cheng)系統來完成(cheng)其使(shi)(shi)用(yong)(yong)(yong)(yong)功(gong)能(neng)。但其連接(jie)(jie)(jie)導線(xian)(xian)(xian)或(huo)電(dian)纜(lan)不可能(neng)無限長(chang)，而(er)且在連接(jie)(jie)(jie)過(guo)程中(zhong)有(you)很多地方(fang)需(xu)要串聯、并聯進行導線(xian)(xian)(xian)分接(jie)(jie)(jie)。這就勢必(bi)造成(cheng)接(jie)(jie)(jie)頭部分外露(lu)，容易引發事故。防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)是(shi)(shi)各種高危場所使(shi)(shi)用(yong)(yong)(yong)(yong)的(de)特殊設備，和民(min)用(yong)(yong)(yong)(yong)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)比，它是(shi)(shi)經(jing)過(guo)各種防(fang)爆(bao)(bao)改造而(er)成(cheng)的(de)具有(you)防(fang)爆(bao)(bao)功(gong)能(neng)的(de)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)。采用(yong)(yong)(yong)(yong)鋁(lv)合金壓鑄或(huo)者是(shi)(shi)采用(yong)(yong)(yong)(yong)不銹(xiu)(xiu)鋼(gang)焊接(jie)(jie)(jie)而(er)成(cheng)，防(fang)爆(bao)(bao)防(fang)腐接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)按分類(lei)有(you)：根(gen)據功(gong)能(neng)材質形(xing)式分為：本安型(xing)防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)、鋁(lv)合金防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)、不銹(xiu)(xiu)鋼(gang)防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)，鋼(gang)板防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)；根(gen)據使(shi)(shi)用(yong)(yong)(yong)(yong)結構又分為：壁(bi)掛式防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)和立式防(fang)爆(bao)(bao)接(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)(xiang)(xiang)。
　　
　　防(fang)爆接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)類(lei)(lei)產(chan)(chan)(chan)品(pin)就是為(wei)解決這(zhe)(zhe)類(lei)(lei)問題(ti)而(er)生產(chan)(chan)(chan)的產(chan)(chan)(chan)品(pin)，以求進(jin)一(yi)步保證安全生產(chan)(chan)(chan)。這(zhe)(zhe)類(lei)(lei)產(chan)(chan)(chan)品(pin)包(bao)括接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)箱(xiang)、接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)盒、穿線(xian)(xian)(xian)盒、吊線(xian)(xian)(xian)盒、分(fen)線(xian)(xian)(xian)盒等產(chan)(chan)(chan)品(pin)，其外殼主要(yao)(yao)由鑄造鋁合金(jin)制(zhi)造。根據(ju)需要(yao)(yao)設有(you)很多(duo)進(jin)線(xian)(xian)(xian)和(he)出線(xian)(xian)(xian)引入裝(zhuang)置，箱(xiang)內(nei)裝(zhuang)有(you)接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)端子(zi)，用來進(jin)行連接(jie)(jie)(jie)(jie)或(huo)分(fen)接(jie)(jie)(jie)(jie)之(zhi)用。這(zhe)(zhe)類(lei)(lei)產(chan)(chan)(chan)品(pin)大部分(fen)制(zhi)成隔爆型或(huo)增安型，體(ti)積有(you)大有(you)小，差異(yi)較大，防(fang)爆等級可(ke)達ⅡC級。
　　
　　防(fang)爆接線(xian)箱的(de)正(zheng)確安裝(zhuang)與(yu)維修(xiu)方(fang)法：防(fang)爆接線(xian)箱安裝(zhuang)前應檢查銘牌上(shang)的(de)技(ji)術數據(ju)是否與(yu)實際使用情況相符(fu)；防(fang)爆接線(xian)箱的(de)內(nei)外接地必須良好可靠；檢查所有(you)緊(jin)固(gu)件是否有(you)松動(dong)現象；安裝(zhuang)時保證密封及電纜不(bu)得松動(dong)以及維修(xiu)檢查時必須先(xian)斷開電源方(fang)可操作，具(ju)體的(de)詳細信(xin)息將(jiang)由提(ti)供防(fang)爆接線(xian)箱價格(ge)的(de)廠家(jia)小(xiao)編為大家(jia)介(jie)紹。
　　
　　安裝前應(ying)檢(jian)(jian)查銘牌(pai)上的(de)技術數據(ju)是否與實際(ji)使(shi)用情況相符(fu)；檢(jian)(jian)查所有(you)緊固件是否有(you)松(song)(song)動現(xian)象，如有(you)松(song)(song)動應(ying)加以(yi)緊固；接線箱的(de)內外(wai)接地必須良(liang)好可靠；安裝時需將電纜(lan)穿過密封圈、金屬(shu)墊圈、用壓緊螺(luo)母壓緊，保證(zheng)密封及電纜(lan)不得松(song)(song)動，不使(shi)用的(de)接線口應(ying)用密封圈和金屬(shu)墊片加以(yi)封堵；維修檢(jian)(jian)查時必須先斷開電源后方可開蓋(gai)。
