摘　　要：随着重载铁路、高速铁路的快速发展,牵引网载荷量逐渐增加,在某些线路区段易引发牵引网末端电压过低,造成列车无法通行。文章探讨了牵引网电压损失的基本原理和影响因素,分析了在牵引网末端采用平衡供电技术实现牵引网末端电压提升的原理,为我国电气化铁路牵引供电的高效、安全运行提供参考。With the rapid development of heavy-duty railway and high-speed railway,the load level of traction network increases gradually.It may easily cause the too low terminal voltage of traction network,which leading locomotive stop running.This paper analyzes the basic principle and influencing factors of the traction network voltage loss,and analyzes the principle of the terminal voltage rise of overhead contact system,using the balanced power supply technology,and provides a reference for the efficient and safe operation of the electrified railway traction power supply in China.
