4、.這是與有利散熱否有關(guān)的.一般相差10%以下立放有利空氣流通,橫放散熱差,特別是機械強度更差,一般不用。就散熱的這個方面,當母線寬度≤63時,平放是立著方0.95左右,當寬度≥63時,平放是立著方0.92左右40℃時銅排載流量=排寬*厚度系數(shù) 排寬(mm);厚度系數(shù)為:母排12厚時為20;10厚時為18;依次為: [12-20,10-18,8-16,6-14,5-13,4-12,3-11,2-10,1-8]雙層銅排[40℃]=1.56-1.58單層銅排[40℃](根據(jù)截面大小定) 3層銅排[40℃]=2單層銅
5、排[40℃] 4層銅排[40℃]=單層銅排[40℃]*2.45(不推薦此類選擇,最好用異形母排替代)) 銅排[40℃]=銅排[25℃]*0.85 鋁排[40℃]=銅排[40℃]/1.3? 例如求TMY100*10載流量為: 單層:100*10=1860A????[查手冊為1860A]????雙層:2【100*10】的載流量為: ?。保福埃?1.58=2940(A);[查手冊為2942A]; ????三層:3(TMY100*10)的載流量為:1860*2=3720(A)[查手冊為3780A] ????以
