地铁与电气化铁路的牵引供电系统比较研究

Comparative Study on Traction Power Supply System of Metro and Electrified Railway

我国电力牵引系统技术的发展已走在世界的前沿。牵引供电系统是一套结构复杂、精度极高的系统,要在实际运行中保障其安全性,使其供给合格、稳定的电力,才能确保地铁和电气化铁路的安全运行。在地铁和电气化铁路的运行过程中要做好牵引供电系统的检查和维护工作,寻找系统的薄弱环节,同时要制定相应的应急预案,全方位地提升地铁、高铁以及电气化铁路牵引供电系统可靠性。

The development of electric traction system technology in our country has been at the forefront of the world.The traction power supply system is a system with complex structure and high precision.Therefore,it is necessary to ensure its safety during actual operation and make its supply qualified and stable.Electricity,thus ensuring the safe operation of subways and electrified railways.In the course of the operation of subways and electrified railways,the inspection and maintenance of traction power supply systems must be well done to find weaknesses in the system.At the same time,corresponding emergency plans must be formulated to enhance the reliability of traction power supply systems for high-speed rail and electrified railways.
