Exploration on the high-quality development of urban rail transit power supply system
To achieve the sustainable high-quality development of urban rail transit,this article analyses the challenges faced by the power supply system,reviews the development overview of the power supply system,and the exploration and application of technologies related to the high-quality development of urban rail transit supply system in recent years is discussed in detail.The advantages and benefits of the novel electric traction system and resource sharing in the main substation are expounded,the specific implementation plan for the utilization of train braking energy is put forward,the principle of the selection of OCS system suspension mode is clarified,the issue of stray current corrosion protection is analyzed,and two specific implementation plans for the use of return conductor rail and the use of a novel rail fully insulated fastener system are proposed,it is proposed to build an intelligent operation and maintenance system for urban rail transit power supply,and fully apply green and low-carbon technologies such as energy-saving transformers and photovoltaic power generation.
