要想(xiang)在(zai)房(fang)間里布線(xian),電(dian)(dian)(dian)線(xian)的(de)(de)(de)直徑是一個(ge)(ge)(ge)必須要考慮的(de)(de)(de)問題,如(ru)何根據(ju)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)率(lv)(lv)(lv)的(de)(de)(de)大小,來選(xuan)擇(ze)電(dian)(dian)(dian)線(xian)的(de)(de)(de)粗(cu)細(xi)。電(dian)(dian)(dian)器(qi)(qi)(qi)有空調、電(dian)(dian)(dian)熱水器(qi)(qi)(qi)、電(dian)(dian)(dian)飯鍋(guo)、冰箱、電(dian)(dian)(dian)磁爐(lu)、紅(hong)外取暖器(qi)(qi)(qi)等,當然這(zhe)(zhe)些電(dian)(dian)(dian)器(qi)(qi)(qi)不可能同(tong)時(shi)(shi)開著,那么應該如(ru)何去選(xuan)擇(ze)預埋電(dian)(dian)(dian)線(xian)呢?查百度得(de)知(zhi),如(ru)果按2.5平方(fang)毫米(mi)的(de)(de)(de)銅(tong)導線(xian)計算,可以(yi)通過的(de)(de)(de)安全(quan)電(dian)(dian)(dian)流(liu)(liu)是2.5*8=20A,有了(le)(le)這(zhe)(zhe)個(ge)(ge)(ge)數據(ju),就可以(yi)按功(gong)率(lv)(lv)(lv)來計算同(tong)時(shi)(shi)可以(yi)工作的(de)(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)了(le)(le)。如(ru)1.5匹(pi)空調的(de)(de)(de)啟動最大電(dian)(dian)(dian)流(liu)(liu)10A,普(pu)通電(dian)(dian)(dian)熱水器(qi)(qi)(qi)工作電(dian)(dian)(dian)流(liu)(liu)在(zai)5A左右(you),電(dian)(dian)(dian)飯鍋(guo)工作電(dian)(dian)(dian)流(liu)(liu)在(zai)5A以(yi)下,電(dian)(dian)(dian)磁爐(lu)的(de)(de)(de)工作電(dian)(dian)(dian)流(liu)(liu)在(zai)10A左右(you),紅(hong)外取暖器(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)在(zai)6A左右(you),這(zhe)(zhe)些都是大功(gong)率(lv)(lv)(lv)電(dian)(dian)(dian)器(qi)(qi)(qi)了(le)(le)。這(zhe)(zhe)些大功(gong)率(lv)(lv)(lv)電(dian)(dian)(dian)器(qi)(qi)(qi)同(tong)時(shi)(shi)工作不要超(chao)過三(san)個(ge)(ge)(ge),如(ru)果同(tong)時(shi)(shi)工作兩個(ge)(ge)(ge)的(de)(de)(de)話還是可以(yi)的(de)(de)(de)。
如(ru)果(guo)(guo)家(jia)里沒有(you)(you)開空(kong)調,那么(me)同時(shi)(shi)有(you)(you)三個(ge)電(dian)器(qi)工作(zuo),還是可以(yi)的(de)(de)。特別注意,空(kong)調和(he)電(dian)磁爐是功率(lv)最大的(de)(de)電(dian)器(qi),這(zhe)兩個(ge)大功率(lv)電(dian)器(qi),盡量不要同時(shi)(shi)工作(zuo)。如(ru)果(guo)(guo)用快速電(dian)熱(re)水器(qi),那么(me)需(xu)要單(dan)獨布線,快速電(dian)熱(re)水器(qi)的(de)(de)功率(lv)達(da)到3000W,因(yin)此需(xu)要4平方的(de)(de)銅導線單(dan)獨供電(dian),這(zhe)種電(dian)器(qi)對導線的(de)(de)要求太高了。
2.5平方(fang)單股銅(tong)(tong)線與多(duo)股銅(tong)(tong)線有(you)區別嗎?個人認為(wei)還是單股銅(tong)(tong)線比(bi)較好(hao),缺點(dian)是硬度高,容(rong)易拆(chai)斷或在布(bu)線時,由于被(bei)拆(chai)后,電阻(zu)率增加(jia)而影響使用。現在的一些(xie)(xie)(xie)黑心商人,會(hui)把一些(xie)(xie)(xie)劣質(zhi)的銅(tong)(tong)導(dao)線賣出(chu)來,那(nei)一定會(hui)很(hen)可(ke)怕,和拿一個拖(tuo)線板去帶動一個空調,那(nei)些(xie)(xie)(xie)多(duo)股銅(tong)(tong)導(dao)線會(hui)發(fa)熱發(fa)燙,甚(shen)至會(hui)起(qi)火,這種因過(guo)載而引發(fa)的火災,是很(hen)可(ke)怕的。
