大连地铁UPS设备维修技术分析

Analysis on Maintenance Technology of UPS Equipment in Dalian Metro

大连地铁通信电源UPS设备采用的是维谛技术UL33系列产品,该系列产品具有较好的稳定性,可以为负载提供不受电网干扰、稳压且稳频的电力。通过调查了解,UPS功能为外部供电故障时,将蓄电池能量转化为供电,输送给外部设备。对于UL33的UPS产品来说,其采用的是全自动数字控制技术,具备很完备的网络管理功能,因此在很多地铁UPS设备中是比较常见的。以大连地铁UPS设备为研究对象,详细探讨大连地铁UPS设备的具体维修技术内容,从而为后续进一步提升UPS维检修水平提供一定的理论支撑。

The UPS equipment of Dalian Metro’s communication power supply adopts the UL33 series products of Weidi Technology,This series of products has good stability and can provide the load with power that is not interfered by the power grid,and is stable and frequency stable.According to the investigation,UPS is mainly to convert the battery energy into power supply and deliver it to external equipment in case of external power supply failure.Therefore,for Ul33 UPS products,it adopts fully automatic digital control technology and has complete network management function.Therefore,it is common in many subway UPS equipment.Therefore,this article will also take the UPS equipment of Dalian Metro as the research object,and discuss the specific maintenance technology of UPS equipment of Dalian Metro in detail,so as to provide a certain theoretical basis for further improving the maintenance level of ups.
