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.
