城轨列车的动力源泉

This course will take you through the power supply system of urban rail transit, including the supply process, methods, locations, and experiences of transforming electricity from 35kV AC into 1500V DC, which is then fed into the overhead contact wires, transmitted to electric trains, and completes the entire process of train power supply through rails and return lines to the traction substations. Additionally, we will discuss the composition, functions, and operation methods of power equipment in substations, the structure, main equipment, core components, and typical structures of overhead flexible contact wires, overhead rigid contact wires, and contact rails. We'll explore the installation and maintenance scenes of contact wire equipment and the operation of unmanned traction substations.

带你了解城轨供电制，供电过程，供电方式，供电场所，带你体验从35kV交流电变为1500V直流电并馈送到接触网、输送给电动列车，再从电动列车经钢轨、回流线流回牵引变电所完成列车供电的完整流程；还会跟你一起探讨变电所电力设备的构成、作用、运行方式，架空柔性接触网、架空刚性接触网和接触轨的组成、主要设备、核心零部件和典型结构，对接触网设备进行安装和检修的震撼场景，以及无人值守变电所的工作情况。
