塔式起重机
Kx = 0.85 Cosφ = 0.6 tgφ = 1.33
将Jc =40%统一换算到Jc1 =25%的额定容量
Pn = 31.7kW
Pe = n×(Jc/Jc1)1/2×Pn = 1×(0.4/0.25)1/2×31.7 = 40.1 kW
Pjs = Kx×Pe =0.85×40.1 = 34.08kW
Qjs = Pjs× tgφ=34.08×1.33 = 45.44 kvar
(2)、建筑施工外用电梯
Kx = 0.85 Cosφ = 0.6 tgφ = 1.33
Pjs = 0.85×11 = 9.35 kW
Qjs = Pjs× tgφ=9.35×1.33 = 12.47 kvar
塔吊铭牌暂载率为0.4,实际暂载率为0.25,换算后塔吊实际功率增大,超过原来的实际功率,系数是否有问题,换算后的实际功率应该比原有的小吧?施工外用电梯在软件里不需要乘系数的?如果要查找这些系数豆豆网里面能否查到??
