UPS电源在朔黄铁路信号系统中的应用分析

朔黄铁路信号系统由自闭和贯通两路电源供电,互为热备用。由于外部电源自动重合闸、备自投与信号切换时限不匹配,信号切换装置存在闪断等问题,导致无法满足信号系统不间断供电的要求,需要配置一套安全可靠的信号供电系统。重点介绍朔黄铁路信号系统UPS电源解决方案及其配置,对信号电源UPS系统的性能特点进行分析。

Application of UPS in Shuohuang Railway Signal System

Shuohuang railway signal system is supplied with two ways of power supplies for automatic blocking and power continuous lines, and they are hot standby each other. Since there are problems such as the external power supply automatic reclosing, standby power unmatched with the signal switching time and flashing of signal switching device, the requirement for uninterrupted power supply of the signal system cannot be met. So it is necessary to configure a safe and reliable signal power supply system. The paper focuses on the UPS power solution and its configuration for Shuohuang railway signal systems, and gives an analysis of the performances and characteristics of the UPS system.
