一种铁路信号“增强型”后备式UPS方案的提出与实现

Realization of "Enhanced" Back-up UPS Solution for Railway Signal Systems

在综合分析目前常用的几种UPS工作方式的基础上,根据铁路信号系统的行业规范和特殊要求,提出一种铁路信号"增强型"后备式UPS方案,并从电路实现上着力解决逆变器与参数稳压器配合的技术难题。作为组成铁路信号电源系统的核心,经过现场考验,达到了设计要求。

Based on the comprehensive analysis of the commonly used UPS working modes at present, the paper puts forward a kind of railway signal ＂enhanced＂ back-up UPS solution according to the industry standard and special requirements of railway signal systems, to resolve the technical problem of adaption between the inverter and parameter voltage stabilizer from the circuit realization. As the core of the railway signal power supply system, it is proved that the UPS solution can meet the design requirements by the fi eld test.
