摘要
针对广州地铁三北线白云大道北站UPS故障无法转静态旁路,导致所有负载掉电的问题,从3号线信号系统电源供电原理入手,对信号系统各级电源故障风险点进行细致分析排查,通过制定、落实整改方案和优化应急措施,以避免或降低电源故障对运营带来的影响。
All loads powered down because the UPS of the Baiyun Road North station ot Guangzhou Mtero No. 3 North line failed. Starting from the principle of the power supply of the signal system in the No. 3 line, risk points of power failure of every level of the signal system are analyzed. Through formulating a rectification plan and optimizing emergency measures, the impact of power supply failure on operation can be avoided or reduced.
