D銅=(ρ銅/ρ鋁(lv))1/2 *D鋁(lv)

D銅:銅線直徑

D鋁:鋁線直徑

ρ鋁(lv):鋁(lv)的電阻率，取1/35.5

ρ銅(tong):銅(tong)的(de)電阻率，取1/58

注：公式中1/2是(shi)(shi)指開平方，銅漆包(bao)線批發，而不(bu)是(shi)(shi)乘(cheng)。

如(ru)：使用(yong)0.51㎜的(de)鋁(lv)漆包(bao)線(xian)，改為(wei)使用(yong)銅(tong)線(xian)時，銅(tong)線(xian)的(de)線(xian)徑為(wei)D銅(tong)=(35.5/58)1/2*0.51=0.6121 1/2*0.51=0.7823*0.51=0.4 。即0.51㎜鋁(lv)漆包(bao)線(xian)改為(wei)銅(tong)漆包(bao)線(xian)后需用(yong)0.40㎜銅(tong)線(xian)代替。

鋁線電機換銅線的注意事(shi)項

取(qu)原(yuan)(yuan)來(lai)鋁線(xian)(xian)截面積的80%，就是代(dai)替后銅線(xian)(xian)的截面積，按原(yuan)(yuan)來(lai)數據(ju)嵌線(xian)(xian)；或(huo)者繞組的匝(za)數按原(yuan)(yuan)數據(ju)；銅線(xian)(xian)線(xian)(xian)徑可按鋁線(xian)(xian)線(xian)(xian)徑的80%或(huo)原(yuan)(yuan)線(xian)(xian)徑即可

聚酰亞an漆包線

聚酰(xian)亞an是目(mu)(mu)前有(you)機(ji)類漆(qi)(qi)(qi)包線(xian)(xian)中耐熱等級zui高的漆(qi)(qi)(qi)包線(xian)(xian)漆(qi)(qi)(qi)，其長期使用(yong)溫度可達220°C以上。該漆(qi)(qi)(qi)由美國于1958年研制成功。聚酰(xian)亞an漆(qi)(qi)(qi)包線(xian)(xian)具(ju)有(you)高的耐熱性，良(liang)好(hao)的耐溶劑(ji)和(he)(he)耐冷(leng)凍劑(ji)性能(neng)。但(dan)由于成本昂貴(gui)，儲存穩定性差和(he)(he)具(ju)有(you)毒(du)性，銅漆(qi)(qi)(qi)包線(xian)(xian)價格，影響(xiang)了它的廣泛(fan)使用(yong)。目(mu)(mu)前該漆(qi)(qi)(qi)包線(xian)(xian)使用(yong)某些特殊場合，如煤礦(kuang)電機(ji)，宇宙空(kong)間儀(yi)器儀(yi)表(biao)等用(yong)線(xian)(xian)

聚氨酯漆包線

聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)包(bao)(bao)(bao)線漆(qi)(qi)(qi)是德國拜耳(er)于1937年(nian)開發(fa)(fa)研制，無(wu)錫銅漆(qi)(qi)(qi)包(bao)(bao)(bao)線，由(you)于其(qi)具有(you)直焊性(xing)(xing)，耐(nai)(nai)高頻性(xing)(xing)能和可(ke)染(ran)色特性(xing)(xing)，因此(ci)在電子、電器(qi)等領域(yu)中被廣泛應(ying)用。目(mu)前(qian)(qian)國外(wai)對提高聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)包(bao)(bao)(bao)線的(de)耐(nai)(nai)熱(re)等級(ji)同(tong)時又(you)不影響其(qi)直焊性(xing)(xing)能極為關注。在歐洲、美國、日(ri)本已先后研制成(cheng)了F級(ji)、H級(ji)聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)包(bao)(bao)(bao)線。由(you)于彩(cai)電的(de)快速發(fa)(fa)展，日(ri)本研制出(chu)的(de)彩(cai)電FBT用大長度(du)無(wu)鹽水zhen孔(kong)的(de)聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)包(bao)(bao)(bao)線引起各國界的(de)注意(yi)，銅漆(qi)(qi)(qi)包(bao)(bao)(bao)線生(sheng)產廠(chang)家，目(mu)前(qian)(qian)仍(reng)然是日(ri)本ling先? ?。國內聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)包(bao)(bao)(bao)線的(de)發(fa)(fa)展緩慢，普(pu)通的(de)聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)雖有(you)一些廠(chang)生(sheng)產，但由(you)于工藝性(xing)(xing)差，表面質(zhi)量等問(wen)題(ti)，因此(ci)漆(qi)(qi)(qi)主(zhu)要(yao)還是靠(kao)進口。F級(ji)聚(ju)氨(an)(an)酯(zhi)(zhi)國內也已開發(fa)(fa)，但未形成(cheng)生(sheng)產能力。大長度(du)無(wu)zhen孔(kong)聚(ju)氨(an)(an)酯(zhi)(zhi)漆(qi)(qi)(qi)也已開發(fa)(fa)成(cheng)功，投放(fang)市場，主(zhu)要(yao)用于制作黑白電視機(ji)FBT線圈? ?。
