柴油发电机组带电焊机所需功率计算办法

柴油发电机组带电焊机功率计算办法:

电焊机的实际电流乘以0.04再加20等于负载电压

负载电压乘以电流等于焊机功率

焊机功率220v电压时乘以1.7,380v时乘以1.4这个是损耗和电焊机功率因素,得出来就是所需要发电机小功率。

实际销售中发电机组功率只要大于计算得到功率即可。

比如机器实际电流160A

计算发电机组功率大小:

160A*0.04 20=26.4V

26.4V*160A=4224W

4224W*1.7等于7180W,也就是说机器至少需要8KW瓦以上的发电机组才可以使用。

以此类推。

公式:

1、220V电压:(电焊机电流*0.04 20)*电焊机电流*1.7=所需发电机组功率

2、380V电压:(电焊机电流*0.04 20)*电焊机电流*1.4=所需发电机组功率
