As everyone knows, the Qinghai-Tibet railway was opened to traffic in our country is carried out western big development strategy is of great significance. But you know, this time at an altitude of 3600 meters altitude, a set of InfraStruXureTM ( APC company to fly the British system ) 40KVA and two Silcon ( silcon ) 40KVA UPS solution is for Qinghai-Tibet Railway Station - Lhasa train station communication building equipment normal operation to provide a stable power supply! In fact, as early as two years ago to start the Qinghai-Tibet Railway command communication system has a set of InfraStruXure 40KN+1, in the city of Xining Tibetan railway construction headquarters is put into use. In addition, as a full range of UPS supplier APC Smar t -UPS by virtue of excellent performance has been widely used in Qinghai-Tibet Railway project.
Railway information system is an important technical support, is the Qinghai-Tibet railway traffic safety, improve transport efficiency guarantee. Only the use of advanced management mode, in order to achieve " maintenance-free, basic unmanned management, at the same time to meet the Qinghai-Tibet Railway Company in data sharing, focus on aspects of demand, timely and effectively call and management of each station business ". In view of the particularity of the Qinghai-Tibet railway and a variety of needs, in each UPS manufacturer product in high altitude environment carried out rigorous testing and comprehensive inspection, the Qinghai-Tibet railway company that APC company InfraStruXure and Silcon system in alpine, Taka Mi, low air pressure and other various conditions show a good stability and reliability, and can fully meet the the Qinghai-Tibet Railway Construction needs. At the same time, APC company covering the whole of the after sale service system and 24 hours of non-stop round-the-clock service for Qinghai-Tibet Railway Company is very satisfied with. Finally, APC winning the success of Lhasa train station communication building project.
Responsible for the project related technical personnel evaluation of such APC solution: " in equipment selection process, the Qinghai-Tibet railway company mainly consider the following three points: first, to ensure high availability, in field circumstances allow, using redundant power supply mode; secondly, to provide a set to be able to follow the actual demand, flexible adjustment capacity of the power supply system; finally, manage / monitor is convenient, easy to maintain. A PC InfraStruXure and Silcon solutions, good to meet the above three requirements, so APC is the best choice for Qinghai-Tibet railway! "
In the actual implementation of the programme, APC engineers and related technical personnel for Qinghai-Tibet railway station train Lhasa communication building load and room layout, using 1 sets of 40KVA/40KW UPS on the engine room all devices in the power supply, the system uses the on-demand configuration mode, the complete system consists of the following components: a modular the UPS component; hot plugging support means of the input / output power distribution cabinets, provide up to 42 road 14 road 3 single-phase output or output ( or two mixed ); a new generation of network equipment cabinet (19 inches ), to optimize the use of improved equipment cooling design, to strengthen the bearing capacity, flexible attachment complete cabinet; temperature and humidity monitoring scheme, can make the room temperature and humidity are precisely controlled, to help customers realize the operation of the equipment well; in addition, with APC to develop information monitor system on the whole monitor, the monitor can automatically identify the access system of new hardware, and management.
The InfraStruXure 40KW N+1 UPS host as the whole room core power supply equipment. Set configuration includes 5 power module ( each power module 10KW ), 1 static bypass module and other control system, this design allows each module online hot replacement. The host output capacity of the largest 40KVA/40KW, to further improve the UPS system reliability, adopted the N+1 approach, whereby the load within 40KW, any of the 1 power module has fault-tolerant design, guarantee system in a single module failure, can still work normally, normally all module load sharing, any module the fault will cause the system interrupt. Lhasa train station communication building equipment to provide the stable power guarantee.
