摘要:
成都轨道交通13号线为线路等级速度140 km/h的市域轨道交通快线，采用交流25 kV供电方式，需要设置电分相。在电分相区段，列车需断电惰行通过，由此产生的速度损失对运营影响较大。结合牵引计算，分析了电分相设置对速度的影响，以及对线路坡度、站间距的要求。通过优化该线的平纵断面，实现了列车在通过该线3处电分相的速度损失均小于10%的目标。基于13号线的设计经验，提出了市域快线电分相位置设置的几个重要原则。
Abstracts:
Chengdu Metro Line 13 is an urban express line with the line grade speed of 140 km/h, which adopts the AC 25 kV power supply mode and needs to set electric split phase. In the electric split phase section, train needs to power off and slide through, the speed loss caused by which impacts the operation to certain extent. Combined with traction calculation, the influence of electric split phase setting on speed is analyzed, as well as the requirements for line slope and station spacing. By optimizing the horizontal and vertical sections of the line, it has been achieved that the speed loss of train passing through three electric split phases of the line are all less than 10%. Based on the design experience of Chengdu Metro Line 13, several important principles for setting the location of electric split phase of urban express line are put forward.
