摘　　要：结合地铁区间射流风机供配电的实际情况,依据相关规范对风机起动时母线电压降、电动机端子电压降、起动转矩等方面的要求,对射流风机在全压起动、软起动2种不同起动方式下的载流量、电压降等指标进行计算,并对2种起动方式的技术经济进行对比分析,进而得到30 kW、45 kW、55 kW等常用规格区间射流风机在不同供电距离下适宜采用的起动方案。Considering the actual power supply situation of jet fans in metro interval and the technical specifications related to fan starting,such as bus voltage drop,motor terminal voltage drop,starting torque,the calculation of current carrying capacity and cable voltage drop of jet fan under 2 different starting modes of direct starting or soft starting is conducted.The two starting modes are compared and analyzed technically and economically.The starting scheme suitable for jet fan of regular power capacity(30 kW,45 kW,55 kW etc.)at different power supply distances is concluded.
