一种电力UPS系统整体改造中新旧设备在线不停电的更换方法

An online and non-stop replacement method for new and old equipment in the overall transformation of power UPS system

近年来,电力系统变电站中各级监控系统向智能化、集成化及应用化方向迅猛发展,由此对关键二次设备供电的可靠性提出了更高的要求。文章研究了电力系统变电站中新旧UPS系统改造全程不间断供电技术,提出了一种电力UPS系统整体改造中新旧设备在线不停电的更换方法,利用自主研制的新旧机柜不断电更换设备和不间断切换装置,实现了电力UPS系统整体改造全程全部负载的不间断供电。

In recent years,monitoring systems at all levels in power system substations have developed rapidly in the direction of intelligence,integration and application,which has put forward higher requirements for the reliability of the power supply of key secondary equipment.This article is devoted to the whole-process uninterrupted power supply technology of the new and old UPS systems in power system substations.It proposes a method for online and non-stop replacement of new and old equipment in the overall reconstruction of power UPS systems.It uses self-developed new and old cabinets to continuously power replacement equipment and uninterrupted switching.The device realizes the uninterrupted power supply of all loads throughout the entire transformation of the power UPS system.
