The signal system for urban rail transit can ensure train operation safety, increase transportation efficiency, improve the working environment, and promote management modernization. Therefore, a stable and reliable power subsystem is crucial for the stable and reliable working of the signal system. This paper analyzes the structure schemes of the signal power subsystems of Nanning Rail Transit Line 1 to Line 5. By summarizing the advantages and disadvantages of diff erent structure schemes, and considering the actual situation at the site, it puts forward the asymmetric double bus redundancy scheme, to improve the stability, safety and reliability of the power subsystem, so as to meet the power supply needs of the signal system for urban rail transit.
