非标铜排载流量表

1、矩形母线载流量计算：40 C时铜排载流量=排宽*厚度系数排宽(mm)；厚度系数为：母排12厚时为20.5;10厚时为18.5;依次为：12-20.5, 10-18.5 , 8-16.5, 6-14.5, 5-13.5, 4-12.5注:根据ly建议和进一步核算，将原厚度系数20,18,16,14,12分别加0.5 ,更加接近。表1序号排厚(mm)厚度系数11220.521018.53816.54614.55513.56412.57311.18双层铜排40C=(1.561.58)*单层铜排40 C(根据截面大小定)3层铜排40 C =2*单层铜排40 C 4层铜排40

2、C =单层铜排40 C *2.45(不推荐此类选择，最好用异形母排替代)铜排40 C =铜排25 C *0.85铝排40C=铜排40C/1.3例如求TMY 100*10载流量为：单层：100*18.5 =1850 (A)查手册为 1 8 6 0 A;双层：2 (TMY10 0 *10)的载流量为：1850*1.58 =2923 (A);查手册为2 9 4 2 A 三层：3 (TMY10 0 *10)的载流量为：1850*2 =3700 (A)查手册为 3 7 8 0 A 表2序号母排规格载流里1单层铜排120*102220A2单层铜排100*101850A3单层铜排80*81320A4单层铜排
