1.選(xuan)擇的(de)導(dao)(dao)(dao)線(xian)截面應(ying)滿足設備容量(liang)和安全載流量(liang)的(de)要求,銅導(dao)(dao)(dao)線(xian)不(bu)(bu)應(ying)小(xiao)于1 ~ 5毫米;鋁導(dao)(dao)(dao)線(xian)不(bu)(bu)應(ying)小(xiao)于2.5ram2,10mm以下的(de)導(dao)(dao)(dao)線(xian)應(ying)采用單(dan)股(gu)導(dao)(dao)(dao)線(xian),箱(xiang)內不(bu)(bu)應(ying)有二次(ci)導(dao)(dao)(dao)線(xian)接頭(tou)。
2.配電箱接線(xian)(xian)一般采(cai)用(yong)(yong)板后接線(xian)(xian),導(dao)線(xian)(xian)引(yin)出板應(ying)覆(fu)蓋絕(jue)緣(yuan)管(guan),各回(hui)路應(ying)排列整齊,接線(xian)(xian)美(mei)觀(guan),拉線(xian)(xian)時線(xian)(xian)頭不應(ying)損壞線(xian)(xian)芯絕(jue)緣(yuan),導(dao)線(xian)(xian)與(yu)設備連接一般采(cai)用(yong)(yong)端子,較好采(cai)用(yong)(yong)母線(xian)(xian)接線(xian)(xian)。嚴禁自行連接電線(xian)(xian)。
3.當導(dao)體穿過(guo)管(guan)道時,導(dao)體的總橫截面不得超過(guo)保護(hu)管(guan)內徑的40%。管(guan)道中不允許有接頭。穿線時不得損壞導(dao)線。同一保護(hu)管(guan)中的導(dao)線不允許穿過(guo)不同的回路。
4.保(bao)(bao)護管入盒時(shi)(shi),端(duan)部(bu)應(ying)設(she)置保(bao)(bao)護絲箍(gu),保(bao)(bao)護管不(bu)允許(xu)有接頭。引(yin)入(釋放)電纜(lan)時(shi)(shi),保(bao)(bao)護管的內徑(jing)(jing)應(ying)大于(yu)電纜(lan)外徑(jing)(jing)的1.5倍。
5.室(shi)內(nei)配(pei)電箱(xiang)應(ying)安裝在干(gan)燥(zao)、明(ming)亮的(de)(de)地(di)(di)方,不易損壞或(huo)振動,便于(yu)儀表(biao)的(de)(de)操(cao)作和維護。不應(ying)安裝在潮(chao)濕的(de)(de)地(di)(di)方,并應(ying)盡(jin)可能靠近負載中(zhong)心。不允許安裝在水(shui)池或(huo)水(shui)閘中(zhong)。固定(ding)螺栓不得小于(yu)10毫米。
2.配電箱接線(xian)(xian)一般采(cai)用(yong)(yong)板后接線(xian)(xian),導(dao)線(xian)(xian)引(yin)出板應(ying)覆(fu)蓋絕(jue)緣(yuan)管(guan),各回(hui)路應(ying)排列整齊,接線(xian)(xian)美(mei)觀(guan),拉線(xian)(xian)時線(xian)(xian)頭不應(ying)損壞線(xian)(xian)芯絕(jue)緣(yuan),導(dao)線(xian)(xian)與(yu)設備連接一般采(cai)用(yong)(yong)端子,較好采(cai)用(yong)(yong)母線(xian)(xian)接線(xian)(xian)。嚴禁自行連接電線(xian)(xian)。
