昨天,有客戶咨詢道,新房裝修在即,空調該用多大的電線比較好,該怎么計算呢?今天金環宇電線電纜小編跟大伙聊聊這個話題。
用多大的電線,我們得先知道空調的功率,也就是平時我們說的多少瓦(單位是W)、多少匹(單位是P)。“匹”是指馬力,是舊的換算單位,我們國家已經廢除,平時口頭語用的還是比較多,1馬力約等于735W, 1.5匹=1.5*734=1.1KW。我們來溫習下功率的公式,功率U=電壓V*電流I,我們國家的居民生活用電電壓是220V,1匹空調功率大概是735W,我們要算電流I=U/V,也就是735/220≈3.3A,我們知道空調一般可以制冷也可以制熱,制熱功率一般比制冷功率要高些。總而言之,1匹空調電流量小于10A,1.5平方電線在理想狀態下載流量大概是25A,考慮到散熱與電機啟動電流問題,一般建議用2.5平方的電線(34A)。
我們(men)可(ke)以(yi)(yi)用(yong)(yong)(yong)(yong)同樣的(de)辦法大概可(ke)以(yi)(yi)計算得出,2P以(yi)(yi)下空(kong)調額定電(dian)流量都小于10A,也可(ke)以(yi)(yi)用(yong)(yong)(yong)(yong)2.5平(ping)(ping)方的(de)電(dian)線(xian),如果不放(fang)心,可(ke)以(yi)(yi)用(yong)(yong)(yong)(yong)4平(ping)(ping)方的(de)電(dian)線(xian)。一般(ban)家庭(ting)用(yong)(yong)(yong)(yong)的(de)1.5P比較多,我們(men)選1.5平(ping)(ping)方的(de)電(dian)線(xian)就好。我們(men)一般(ban)建議2P以(yi)(yi)下用(yong)(yong)(yong)(yong)2.5平(ping)(ping)方線(xian),2P-4P一般(ban)用(yong)(yong)(yong)(yong)4平(ping)(ping)方電(dian)線(xian)。
電線種類也是比較多,那么我們該選哪種呢?別急,金環宇電線電纜小編會為你解答清楚的。我們可以把電線劃分為硬線與軟線,硬線與軟線本質沒多大區別,只是在排線與接線的時候難易不同,根據電工喜好挑選就好,小編是比較推薦用軟線的,當然軟線也不會非常的軟,只是相對硬線來說的。之所以有軟硬之分,是因為線芯根數決定的,我們可以這么理解,線芯多且細電線就會軟,線芯少且粗就硬。我們可以看看下面這個圖片,可以很好區分兩者的區別。
行業內,我(wo)(wo)們一(yi)般用字(zi)母(mu)表示,“B”是(shi)指(zhi)(zhi)(zhi)布(bu)線(xian)(xian)(xian)用線(xian)(xian)(xian),“V”是(shi)指(zhi)(zhi)(zhi)聚(ju)氯乙(yi)烯,一(yi)般用來做電(dian)線(xian)(xian)(xian)的(de)(de)外皮,“R”就是(shi)軟的(de)(de)意思(si),如果電(dian)線(xian)(xian)(xian)名稱里(li)沒有“R”一(yi)般是(shi)指(zhi)(zhi)(zhi)硬(ying)(ying)線(xian)(xian)(xian),舉(ju)例(li)說明,“BVR”就是(shi)指(zhi)(zhi)(zhi)“銅芯聚(ju)氯乙(yi)烯絕緣軟電(dian)線(xian)(xian)(xian)”,而“BV”就是(shi)“銅芯聚(ju)氯乙(yi)烯絕緣硬(ying)(ying)電(dian)線(xian)(xian)(xian)”,平時我(wo)(wo)們用的(de)(de)比較(jiao)多的(de)(de)一(yi)般是(shi)BVR類電(dian)線(xian)(xian)(xian),因為線(xian)(xian)(xian)不會太硬(ying)(ying),比較(jiao)好接(jie)線(xian)(xian)(xian)與(yu)排線(xian)(xian)(xian),深受電(dian)工師傅的(de)(de)青(qing)睞。
我們去買電(dian)線(xian)(xian)(xian),可(ke)以跟店主說(shuo),我要BVR2.5平方的電(dian)線(xian)(xian)(xian)就好,都能聽(ting)懂。也(ye)可(ke)以直接說(shuo)我想要2.5平方的軟(ruan)線(xian)(xian)(xian),當然這么(me)說(shuo),可(ke)能就有幾(ji)種選擇(ze)了,說(shuo)明使用場景,店主也(ye)會推(tui)薦。
剛剛我(wo)們說了(le)(le),空(kong)(kong)(kong)調因為(wei)有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機,啟動(dong)的(de)時(shi)候電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流比較大,空(kong)(kong)(kong)調功率也(ye)是比較高(gao)的(de),所以(yi),空(kong)(kong)(kong)調一(yi)般是獨(du)立使用(yong)(yong)一(yi)組線(xian)的(de),空(kong)(kong)(kong)調因為(wei)有金(jin)屬外(wai)(wai)殼(ke)(ke),是要(yao)(yao)求外(wai)(wai)殼(ke)(ke)接(jie)地(di)(di)的(de),這(zhe)就要(yao)(yao)求我(wo)們要(yao)(yao)用(yong)(yong)要(yao)(yao)拉火線(xian)、零線(xian)還有地(di)(di)線(xian),要(yao)(yao)用(yong)(yong)到三孔插座(zuo)了(le)(le)。前不久,金(jin)環(huan)宇(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)小(xiao)編(bian)給(gei)大伙分享(xiang)過一(yi)個案例,一(yi)小(xiao)孩子爬(pa)上路(lu)邊(bian)小(xiao)店的(de)空(kong)(kong)(kong)調外(wai)(wai)機上被觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)身亡(wang),所以(yi),為(wei)了(le)(le)安全起見,空(kong)(kong)(kong)調金(jin)屬外(wai)(wai)殼(ke)(ke)要(yao)(yao)接(jie)地(di)(di),還要(yao)(yao)加裝漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)!金(jin)環(huan)宇(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)小(xiao)編(bian)之前強調很多(duo)次(ci)了(le)(le),安全用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)少不了(le)(le)漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)!漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)不貴,可以(yi)的(de)話加裝一(yi)個,空(kong)(kong)(kong)調分支獨(du)立一(yi)個就更(geng)好。
總而言之,我(wo)們家庭用空(kong)調可以用BVR2.5平方電線,空(kong)調金屬(shu)外殼不要忘了(le)接(jie)地!為了(le)安(an)全起見,千萬不能省了(le)漏電開關!當然,主路更(geng)是(shi)少不了(le)的!安(an)全無小事,希(xi)望我(wo)們在使用電器(qi)的時候,要引起我(wo)們的高(gao)度警惕,做好(hao)防范工作,把安(an)全隱患扼殺(sha)在萌(meng)芽狀態!
空調(diao)用(yong)多(duo)大的線,相信已經有(you)答案了,如果(guo)你還有(you)什么問題請與我們聯(lian)系。
