比如直径176的线,就是176÷2×314=276平方≈25平方,(取近似值)。 如果你是要选择电线的大小,一般是先根据用电器的功率大小算出电流,然后根据电流在查电工手册即可,这样比不用这么大功率吧,最小4KW,也可以的。4平方电线丞受倒多少千瓦电力那要看你是家庭220v用电还是工厂380v的了要是220的4平方电线可以负荷6到8个千瓦。 五、6平方电线可以负荷多1、15、25、4、6平方电线可以负荷多少瓦?多少电流? 知乎
Jul 07, 2020· 2kw功率的380v电机额定电流大概在4~5A,那么多大的铜线够用呢? 我们按照16平方毫米以下的铜线按照6倍计算,那么1平方铜线可以承受6A的电流,在100米距离以下都是可以使用的。 不过因为这个截面积电线的价格比较便宜,和15平方的铜线电缆相差不大,所以23kW电机不多见 一般电机都是22kW的 三相380异步电机额定电流一般在45A左右。 如果用铜导线的话6平方就够了 铝导线要加大一号,用10平方的 下面的电流计算口诀可以了解下。 发布于 21:02 注册电气工程师 注册电气工程师(供配电)23千瓦电机用多大电线? 知乎 Zhihu
Dec 16, 2020· 根据口诀“穿管根数二三四,八七六折满载流”可知,穿管3根需要按满载流量的七折计算。 那么电线需要的满载流量等于15÷07=214A。 根据口诀“二点五以下乘以九”,25*9=225A,这个是铝线的安全载流量。 再根据口诀“高温九折铜升级”可知,25平方的铝线185千瓦电机需要6平方的电缆线。 (1)计算方法: 根据三相电相线电流计算公式 I=P÷(U×1732×cosΦ) P功率(W);U电压(380V);cosΦ功率因素(085);I相线电流(A) 带入数据P=185kw,U=380V ; 计算得,相线电流I=33A (2)在三相平衡电路,一般铜导线的安全载流量为5~8A/mm^2。 33÷8=413mm^2,电缆最近的规格为6mm^2185千瓦电机配多大电缆
