地铁牵引供电系统回流设计方案优化

回流系统是保证地铁牵引供电系统可靠运行的一个重要环节。我国地铁早期牵引供电的回流系统设计方案中存在不足之处,有必要进行适当的方案优化。本文在满足系统回流的载流量要求前提下,提出了地铁牵引供电回流系统优化设计方案,并提出工程应用建议。

The return system is an important link to ensure the reliable operation of subway traction power supply system.There are some deficiencies in the design schemes for the early traction power supply return system in subways in China,so it is necessary to implement the scheme optimization.In this paper,on the premise of meeting the current carrying capacity requirements of system return,an optimized design scheme is put forward,and suggestions for engineering application are proposed.
