高寒高铁箱变不间断电源关键技术研究与应用

Research and Application on Key Technology of Uninterruptible Power Supply for High-Cold High-speed Railway Box Substation

不间断电源简称UPS,主要用于保障重要负荷不受停电及电网干扰影响,对于需要连续、稳定供电的用户具有重要意义。本文介绍了在东北高寒地理环境下,UPS在高铁沿线箱变的应用情况及主要问题,并针对高寒地区UPS的应用与维护提出了解决方案。

Uninterruptible power supply(UPS)is mainly used to protect important loads from power failure and power grid interfere nee.It is of great sign ificance to users who need a con tinuous and stable power supply.This paper introduces the application and main problems of UPS in box substations along high-speed railway under the alpine geographical environment of northeast China,and puts forward solutions for the application and maintenance of UPS in alpine areas.
