銅芯電線電纜載流量標(biāo)準(zhǔn)及簡單計(jì)算附流量對照表

銅芯電線電纜載流量標(biāo)準(zhǔn)電纜載流量口決：估算口訣：二點(diǎn)五下乘以九，往上減一順號走。三十五乘三點(diǎn)五，雙雙成組減點(diǎn)五。條件有變加折算，高溫九折銅升級。穿管根數(shù)二三四，八七六折滿載流。說明：本節(jié)口訣對各種絕緣線(橡皮和塑料絕緣線)的載流量(安全電流)不是直接指出，而是”截面乘上一定的倍數(shù)”來表示，通過心算而得?！岸c(diǎn)五下乘以九，往上減一順號走”說的是2．5mm’及以下的各種截面鋁芯絕緣線，其載流量約為截面數(shù)的9倍。如2．5mm’導(dǎo)線，載流量為2．5×9＝22．5(A)。從4mm’及以上導(dǎo)線的載流量和截面數(shù)的倍數(shù)關(guān)系是順著線號往上排，倍數(shù)逐次減l，即4×8、6×7、10×6、16×5、25×4?！叭宄巳c(diǎn)五，雙雙成組減點(diǎn)五”，說的是35mm”的導(dǎo)線載流量為截面數(shù)的3．5倍，即35×3．5＝122．5(A)。從50mm’及以上的導(dǎo)線，其載流量與截面數(shù)之間的倍數(shù)關(guān)系變?yōu)閮蓚€(gè)兩個(gè)線號成一組，倍數(shù)依次減0．5。即50、70mm’導(dǎo)線的載流量為截面數(shù)的3倍；95、120mm”導(dǎo)線載流量是其截面積數(shù)的2．5倍，依次類推?！皸l件有變加折算，高溫九折銅升級”。上述口訣是鋁芯絕緣線、明敷在環(huán)境溫度25℃的條件下而定的。若鋁芯絕緣線明敷在環(huán)境溫度長期高于25℃的地區(qū)，導(dǎo)線載流量可按上述口訣計(jì)算方法算出，然后再打九折即可；當(dāng)使用的不是鋁線而是銅芯絕緣線，它的載流量要比同規(guī)格鋁線略大一些，可按上述口訣方法算出比鋁線加大一個(gè)線號的載流量。如16mm’銅線的載流量，可按25mm2鋁線計(jì)算。計(jì)算電纜載流量選擇電纜（根據(jù)電流選擇電纜）：導(dǎo)線的載流量與導(dǎo)線截面有關(guān)，也與導(dǎo)線的材料、型號、敷設(shè)方法以及環(huán)境溫度等有關(guān)，影響的因素較多，計(jì)算也較復(fù)雜。各種導(dǎo)線的載流量通?？梢詮氖謨灾胁檎?。但利用口訣再配合一些簡單的心算，便可直接算出，不必查表。1.口訣鋁芯絕緣線載流量與截面的倍數(shù)關(guān)系10下五，100上二，25、35，四、三界，.70、95，兩倍半。穿管、溫度，八、九折。裸線加一半。銅線升級算。說明：口訣對各種截面的載流量（安）不是直接指出的，而是用截面乘上一定的倍數(shù)來表示。為此將我國常用導(dǎo)線標(biāo)稱截面（平方毫米）排列如下：1、1.5、2.5、4、6、10、16、25、35、50、70、95、120、150、185……(1)第一句口訣指出鋁芯絕緣線載流量（安）、可按截面的倍數(shù)來計(jì)算?？谠E中的阿拉伯?dāng)?shù)碼表示導(dǎo)線截面（平方毫米），漢字?jǐn)?shù)字表示倍數(shù)。把口訣的截面與倍數(shù)關(guān)系排列起來如下：1～1016、2535、5070、95120以上﹀﹀﹀﹀﹀五倍四倍三倍二倍半二倍現(xiàn)在再和口訣對照就更清楚了，口訣“10下五”是指截面在10以下，載流量都是截面數(shù)值的五倍?！?00上二”（讀百上二）是指截面100以上的載流量是截面數(shù)值的二倍。截面為25與35是四倍和三倍的分界處。這就是口訣“25、35，四三界”。而截面70、95則為二點(diǎn)五倍。從上面的排列可以看出：除10以下及100以上之外，中間的導(dǎo)線截面是每兩種規(guī)格屬同一種倍數(shù)。例如鋁芯絕緣線，環(huán)境溫度為不大于25℃時(shí)的載流量的計(jì)算：當(dāng)截面為6平方毫米時(shí)，算得載流量為30安；當(dāng)截面為150平方毫米時(shí)，算得載流量為300安；當(dāng)截面為70平方毫米時(shí)，算得載流量為175安；從上面的排列還可以看出：倍數(shù)隨截面的增大而減小，在倍數(shù)轉(zhuǎn)變的交界處，誤差稍大些。比如截面25與35是四倍與三倍的分界處，25屬四倍的范圍，它按口訣算為100安，但按手冊為97安；而35則相反，按口訣算為105安，但查表為117安。不過這對使用的影響并不大。當(dāng)然，若能“胸中有數(shù)”，在選擇導(dǎo)線截面時(shí)，25的不讓它滿到100安，35的則可略為超過105安便更準(zhǔn)確了。同樣，2.5平方毫米的導(dǎo)線位置在五倍的始端，實(shí)際便不止五倍（最大可達(dá)到20安以上），不過為了減少導(dǎo)線內(nèi)的電能損耗，通常電流都不用到這么大，手冊中一般只標(biāo)12安。（2）后面三句口訣便是對條件改變的處理。

“穿管、溫度，八、九折”是指：若是穿管敷設(shè)（包括槽板等敷設(shè)、即導(dǎo)線加有保護(hù)套層，不明露的），計(jì)算后，再打八折；若環(huán)境溫度超過25℃，計(jì)算后再打九折，若既穿管敷設(shè)，溫度又超過25℃，則打八折后再打九折，或簡單按一次打七折計(jì)算。

關(guān)于環(huán)境溫度，按規(guī)定是指夏天最熱月的平均最高溫度。實(shí)際上，溫度是變動(dòng)的，一般情況下，它影響導(dǎo)線載流并不很大。因此，只對某些溫車間或較熱地區(qū)超過25℃較多時(shí)，才考慮打折扣。例如對鋁心絕緣線在不同條件下載流量的計(jì)算：當(dāng)截面為10平方毫米穿管時(shí)，則載流量為10×5×0.8═40安；若為高溫，則載流量為10×5×0.9═45安；若是穿管又高溫，則載流量為10×5×0.7═35安。（3）對于裸鋁線的載流量，口訣指出“裸線加一半”即計(jì)算后再加一半。這是指同樣截面裸鋁線與鋁芯絕緣線比較，載流量可加大一半。例如對裸鋁線載流量的計(jì)算：當(dāng)截面為16平方毫米時(shí)，則載流量為16×4×1.5═96安，若在高溫下，則載流量為16×4×1.5×0.9=86.4安。(4)對于銅導(dǎo)線的載流量，口訣指出“銅線升級算”，即將銅導(dǎo)線的的截面排列順序提升一級，再按相應(yīng)的鋁線條件計(jì)算。例如截面為35平方毫米裸銅線環(huán)境溫度為25℃，載流量的計(jì)算為：按升級為50平方毫米裸鋁線即得50×3×1.5=225安.對于電纜，口訣中沒有介紹。一般直接埋地的高壓電纜，大體上可直接采用第一句口訣中的有關(guān)倍數(shù)計(jì)算。比如35平方毫米高壓鎧裝鋁芯電纜埋地敷設(shè)的載流量為35×3=105安。95平方毫米的約為95×2.5≈238安。三相四線制中的零線截面，通常選為相線截面的1/2左右。當(dāng)然也不得小于按機(jī)械強(qiáng)度要求所允許的最小截面。在單相線路中，由于零線和相線所通過的負(fù)荷電流相同，因此零線截面應(yīng)與相線截面相同。300V/1000V電纜載流量現(xiàn)在時(shí)刻：13:10:25
