电缆、电机负载功率计算
自己在电子表格做的很实用。输入参数就得出结果了。
电缆负载功率计算 电缆单相电源负载额定功率P: 额定电压U(KV) 功率因数cosφ 安全载流量I(A) 由电缆平方数确定
参数 0.22 0.9 206 40.788
功率P=U X I X cosφ (KW)
注:绿颜色参数为变量,红颜色参数为计算结果，其他数据不变。 ````````````````````````````````````````````````````
电缆三相电源负载额定功率P: 额定电压U(KV) 功率因数cosφ 计算常量√3￣
参数 0.38 0.9 1.732
安全载流量I(A)由电缆平方数确定 250 功率P=√3￣ X U X I X cosφ (KW) 148.086 注:绿颜色参数为变量,红颜色参数为计算结果，其他数据不变。 ````````````````````````````````````````````````````
