摘要
地铁信号系统是控制列车安全运行的系统,信号系统的电源设备包括信号电源屏(含两路输入电源切换装置)、UPS(不间断电源)和蓄电池组,向信号系统室内控制设备及室外设备不间断地提供所需种类的高品质纯净电源。文中主要对信号电源屏、UPS原理以及监控的组网方式进行分析,提出了地铁信号系统电源设备的配置方案,探讨了电源设备配置过程中应注意的问题,为地铁信号系统电源配置提供参考。
Signalling system is responsible for safe train operation in metro. Its power supply equipment includes signalling power supply cabinet, UPS and battery. Power supply subsystem provides needed kinds of power supply for signalling system. This paper introduces principles and analyzes collocation schemes of signalling power supply equipment. It also has a discussion of some issues that should be paid attention to.
