华为RRU设备直流工作电压－48V 。
设备的直流工作电压范围－36V～－57V
蓄电池组自身压降按0.2V考虑，开关组合电源自身压降按0.3考蓄电池组到开关组合电源压降按2G设备12载频，TD设备1个BBU加3个RRU考虑
0.19=(12*3.5+(300+80*3)/48)*5*2/57/50
直流开关电源按蓄电池保护电压1.85V考虑，蓄电池输出端的电压为44.4V，则到设备工作截至电压36V时，允许的压降为44.4-0.2-0.19-0.3-36=7.72V

电缆压降计算公式
电缆压降计算公式
有个45KW电机，线路长度200m，空气敷设。
考虑压降，需要选多大的电缆呢，最好有计算步骤
45KW电机,功率因数0.85，工作电流约90A。
线路长度200m。
宜选用35平方铜电缆或50平方铝电缆。
35平方铜电缆电压降：1.732*90*0.85*0.0175*200/35＝13V 50平方铝电缆电压降：1.732*90*0.85*0.029*200/50＝15V 这么短的距离只考虑导线的安全电流就可以了
45KW用25平方的铜导线可以满足安全电流
如果按电压损失百分之5计算S=P×L/C×5=23
所以使用25平方的铜导线是符合设计要求的
我想问一下，YJV16平4心铜芯电缆，敷设方式为埋于地下，送到150米外，电压剩多少，计算公式？
在温度=20°C时，铜的电阻系数为0.0175欧姆*平方毫米/米；在温度=75°C时铜的电阻系数为0.0217欧姆*平方毫米/米一般情况下电阻系数随温度变化而变化,在一定温度下导线的电阻=导线的长度*
导线的电阻系数/导线的载面积150米16平方毫米铜导线的电阻在温度=20°C时=150*0.0175/16=0.164(欧姆) 如果只用其中的两条(一条作火线,一条作地线)那线路电阻=0.164欧姆*2(串)=0.328欧姆作负载30安培算线路压降=30*0.328=9.84(伏) 如果两条并联作火线,另两条并联作地线,那线路电阻为0.164欧美,线路压降
=30*0.164=4.92(伏) 具体使用中的线路压降随环境温度、负载变化面变化,计算方法,公式就是这样。
线缆压降估算表
正常工作线路上的电压降，对于正常条件下设备装置的限制（安装设备装置的固定限制条件）。
下表给出计算电压降方法和公式更简单的是，下表格给出了每100m线缆的电压降，对于三相400V/50HZ，和运行电流（设备装置的额定电流）按%的压降。
该电压（%）降与电缆截面和流过的电流大小有关。
这些值对应于电机的co s￠为0.85，对应于非感性负载的co s￠为1.当L≠100m时，可以参照此表，但当考虑修正系数L/100.在正常工作状态下计算线路上的电压降计算电压降表电路压降（V）单相：相间△U=2I B L(R co s￠+Xsin￠)单相：相线和中性线间△U=2I B L(R co s￠+Xsin￠)三相：三相平衡△U=3I B L(R co s￠+Xsin￠)Un：线电压Vn：相电压三相400V/50HZ，长度为100m线缆的压降△U=%Ue cos￠=0.85线缆铜铝S（mm2） 1.5 2.5 4 6 10 16 25 35 50 70 95 120 150 185 240 300 10 16 25 35 50 70 95In（A）1 0.5 0.42 1.1 0.6 0.43 1.5 1.0 0.6 0.4 0.45 2.6 1.6 1.0 0.6 0.4 0.6 0.410 5.2 3.2 2.0 1.4 0.8 0.5 1.3 0.8 0.516 8.4 5.0 3.2 2.2 1.3 0.8 0.5 2.1 1.3 0.8 0.620 6.3 4.0 2.6 1.6 1.0 0.6 2.5 1.6 1.1 0.7 0.525 7.9 5.0 3.3 2.0 1.3 0.8 0.6 3.2 2.0 1.3 0.9 0.6 0.532 6.3 4.2 2.6 1.6 1.1 0.8 0.5 4.1 2.6 1.6 1.2 0.9 0.6 0.540 7.9 5.3 3.2 2.1 1.4 1.0 0.7 0.5 5.1 3.2 2.1 1.5 1.1 0.8 0.650 6.7 4.1 2.5 1.6 1.2 0.9 0.6 0.5 6.4 4.1 2.6 1.9 1.4 1.0 0.763 8.4 5.0 3.2 2.1 1.5 1.0 0.8 0.6 8.0 5.0 3.2 2.3 1.7 1.3 0.970 5.6 3.5 2.3 1.7 1.3 0.9 0.7 0.5 5.6 3.6 2.6 1.9 1.4 1.180 6.4 4.1 2.6 1.9 1.4 1.0 0.8 0.6 0.5 6.4 4.1 3.0 2.2 1.5 1.2100 8.0 5.0 3.3 2.4 1.7 1.3 1.0 0.8 0.7 0.65 5.2 3.8 2.7 2.0 1.5125 4.4 4.1 3.1 2.2 1.6 1.3 1.0 0.9 0.21 0.76 6.5 4.7 3.3 2.4 1.9160 5.3 3.9 2.8 2.1 1.6 1.4 1.1 1.0 0.97 0.77 6.0 4.3 3.2 2.4200 6.4 4.9 3.5 2.6 2.0 1.6 1.4 1.3 0.22 0.96 5.6 4.0 3.0250 6.0 4.3 3.2 2.5 2.1 1.7 1.6 1.53 1.2 6.8 5.0 3.8320 5.6 4.1 3.2 2.6 2.3 2.1 1.95 1.54 6.3 4.8400 6.9 5.1 4.0 3.3 2.8 2.6 2.44 1.92 5.9 4.0500 6.5 5.0 4.1 3.5 3.2 3.0 2.4 6.0cos￠=0.85线缆铜铝S（mm2） 1.5 2.5 4 6 10 16 25 35 50 70 95 120 150 185 240 300 10 16 25 35 50 70 95In（A）1 0.6 0.42 1.3 0.7 0.53 1.9 1.1 0.7 0.5 0.55 3.1 1.9 1.2 0.8 0.5 0.7 0.510 6.1 3.7 2.3 1.5 0.9 0.5 1.4 0.9 0.616 10.7 5.9 3.7 2.4 1.4 0.9 0.6 2.3 1.4 1.0 0.720 7.4 4.6 3.1 1.9 1.2 0.7 3.0 1.9 1.2 0.8 0.625 9.3 5.8 3.9 2.3 1.4 0.9 0.6 3.7 2.3 1.4 1.1 0.7 0.532 7.4 5.0 3.0 1.9 1.2 0.8 0.6 4.8 3.0 1.9 1.4 1.0 0.7 0.5 40 9.3 6.1 3.7 2.3 1.4 1.1 0.7 0.5 5.9 3.7 2.3 1.7 1.2 0.8 0.6 50 7.7 4.6 2.9 1.9 1.4 0.9 0.6 0.5 7.4 4.6 3.0 2.1 1.4 1.1 0.8 63 9.7 5.9 3.6 2.3 1.6 1.2 0.8 0.6 9.0 5.9 3.7 2.7 1.9 1.4 1.0 70 6.5 4.1 2.6 1.9 1.3 0.9 0.7 0.5 6.5 4.1 3.0 2.1 1.4 1.1 80 7.4 4.6 3.0 2.1 1.4 1.1 0.8 0.6 0.5 7.4 4.8 3.4 2.3 1.7 1.3 100 9.3 5.8 3.7 2.6 1.9 1.4 1.0 0.8 0.7 0.6 5.9 4.2 3.0 2.1 1.5 125 7.2 4.6 3.3 2.3 1.6 1.2 1.0 0.9 0.7 0.6 7.4 5.3 3.7 2.6 2.0 160 5.9 4.2 3.0 2.1 1.5 1.3 1.2 1.0 0.8 0.6 6.8 4.8 3.4 2.5 200 7.4 5.3 3.7 2.6 2.0 1.5 1.4 1.3 1.0 0.8 5.9 4.2 3.2 250 6.7 4.6 3.3 2.4 1.9 1.7 1.4 1.2 0.9 7.4 5.3 3.9 320 5.9 4.2 3.2 2.4 2.3 1.9 1.5 1.2 6.8 5.0 400 7.4 5.3 3.9 3.1 2.8 2.3 1.9 1.4 6.2 500 6.7 4.9 3.9 3.5 3.0 2.5 1.9 7.7 对于三相230V电网，此值乘以3=1.73。
