塔式起重機Kx = 0.85 Cosφ = 0.6 tgφ = 1.33將Jc =40%統一換算到Jc1 =25%的額定容量Pn = 31.7kWPe = n×(Jc/Jc1)1/2×Pn = 1×(0.4/0.25)1/2×31.7 = 40.1 kWPjs = Kx×Pe =0.85×40.1 = 34.08kWQjs = Pjs× tgφ=34.08×1.33 = 45.44 kvar(2)、建筑施工外用電梯Kx = 0.85 Cosφ = 0.6 tgφ = 1.33Pjs = 0.85×11 = 9.35 kWQjs = Pjs× tgφ=9.35×1.33 = 12.47 kvar塔吊銘牌暫載率為0.4,實際暫載率為0.25,換算后塔吊實際功率增大,超過原來的實際功率,系數是否有問題,換算后的實際功率應該比原有的小吧?施工外用電梯在軟件里不需要乘系數的?如果要查找這些系數豆豆網里面能否查到??...閱讀全文
