500kw發電機出線電纜計算方法,選多少平方的電纜線

發布日期:2022-10-09 點擊率:31

有關500kw發電機出線電纜的計算方法,500KW發電機該用多少平方的電纜線,500KW發電機用多粗的電纜,電纜線的選擇與計算公式。

500kw發電機出線電纜的計算方法

如果是380v,采用如下的方法估算:

1kw=2A,500=1000A,發電機按80%效率算就是800A,選240平方銅芯電纜就可以了。

500KW發電機該用多少平方的電纜線?

當用電設備是3相電動機或者其他3相負載時,計算公式如下:

根據公式P=根號3*U線*I線*功率因數  而電纜選擇要看其電流大小

即線=P/根號3*U線*功率因數=500000/1.732*380*0.7=1085.2767A

[根號3=1.732,U線=380,功率因數=0.7]

根據每平方毫米6A計算截面S=180.879平方毫米[每相]

可以選用185平方毫米4芯銅芯塑料阻燃電纜一根作為主電源。

以上算法僅供參考.

500KW發電機用多粗的電纜?

你發電機,發出口電壓時多少V 。如果是380v。估算下:1kw=2A,500kw=1000A。發電機按80%效率算就是800A,選240平方銅芯電纜即可。
