摘　　要：市域轨道交通中的交流供电制式[1],虽具有供电区间较长及建设成本较低等优势,但却带来了电分相(无电区)的问题。基于电分相区域的构成,分析了在最不利情况下列车通过电分相区域需要惰行的最长距离。通过理论计算,明确了信号系统在ATO(列车自动运行)控车的情况下列车进入电分相区域入口的最低速度,从而确定了电分相两侧信号机的布点原则、设置电分相的最小站间距长度及所处节能坡的区段位置。The AC power supply system in urban rail transit has the advantages of long power supply interval and low construction cost.However,it also creates the problem of phase separation(in non-power area).According to the composition of phase separation area,the longest phase separation distance that a train needs to idle through in the worst condition is analyzed.Through theoretical calculation,the lowest speed of signal system under ATO(automatic train operation)control is defined when a train enters the phase separation area,thus the distribution principle of signal machines on both sides of the phase separation area,the minimum station spacing length and the location of energy-saving slope are formulated in setting the phase separation.
