功率的计算公式是:单相P=UI*功率因数。由电线平方数对应计算电线的安全载流量。方法1:参照电线安全载流量的对照表来直接可以看到:电线平方数~电线dan xiang he san xiang jiao liu dian liu ji suan gong shi san xiang dian liu : I = P / √ 3 * U * C O S φ jiu shi P = / √ 3 * U * I * C O S φ gong shi de bian xing 。p shi yi zhi gong lv dan wei shi K W , U shi 0. 3 8 K V , C O S φ shi gong lv yin shu , gen ju fu zai xing zhi qu zhi dan xiang dian liu : : I = P / U * C
1平方线: 横截面积是1平方毫米的电线如果我们按照公式:面积=半径²*3.14 来推算那么1平方线=1.13mm左右▶ 01 1平方电线可以负荷多少瓦: 一个电工常用的“经验公式":只要是铜芯电线,每平方毫米的截面积可以安全电线平方知道电线的平方,求电线半径:电线平方数(单位是平方毫米)π(3.14)r(单位是毫米)。如:2.5方电线的线半径的平方是:2.5÷3.14=0.8,开方得出

380v功率与电线平方计算公式电线的截面积越大,承载的电流和功率就越高,而电线截面积的计算公式为:设备额定功率除以电线度再乘以系数K。推荐度:单相和三相交流电流计算公式三相电流:I=P/√3*U*COSφ 就是P=/√3*U*I*COSφ公式的变形。p是已知功率单位是KW,U是0.38KV,COSφ是功率因数,根据负载性质取值单相电流::I=P/U*C
