The rapid development of the national economy has opened up a broad shopping mall space for the growth of the civil aviation industry. In order to meet the surge in the number of flights, an international airport in Northwest China has invested in the third phase of the expansion project, and has been listed as the "number one project" for civil aviation development and the "benchmark demonstration project" for national civil aviation, carrying the serious mission of building a highland for inland reform and opening up and serving the development of the "three economies". Delta's Ultron NT series UPS (uninterruptible power supply) was used in critical loads such as substations and monitoring equipment for lighting stations in the north-south flying area of the third phase of the expansion project to ensure the safety of lighting and electricity in the flying area.
Considering that the safety of electricity in the flying area is of serious significance, and its stability is directly related to the continued safety and stability of the airport's flight operation, therefore, users put forward clear requirements for the performance of the UPS system, mainly including:
If the mains power is interrupted due to power failure or other faults, it is necessary to continue the operation of the critical equipment of the substation, box transformer and lamp station in the north-south flying area before the generator is started;
The load characteristics of the lighting station are messy and scattered, which has an impact on the front-end power supply, and it is necessary for the UPS to be able to cope with the load impact.
With rich experience in the airport industry, Delta has supplied a total of 18 sets of Ultron NT series UPSs for the Phase III expansion project, equipped with a stand-alone system in each region, and the backup time is set to power down at different times according to different usage environments.
The sub-regional small centralized power supply method can solve the problems of scattered load and long-distance power supply in the flying area, and take into account the safe power supply of substations, box transformers and lighting station equipment;
As a power frequency machine, the Ultron NT series UPS has better impact resistance, and cooperates with front-end power quality equipment to ensure the safety of power supply for back-end loads, and also reduce the impact of loads on front-end power distribution circuits.
In addition to the advantages of the above solutions, the Ultron NT series can also customize the input and output additional voltages for various use environments, and its N+X parallel redundancy or system expansion can ensure the power stability and reliability of critical loads. Even in the case of 100% unbalanced load, the Ultron NT series UPS can continue to provide maintenance for equipment operation and save operating costs, coupled with ultra-high reliability and high-density planning, it is ideal for ensuring the safety of critical equipment and providing high standards of maintenance for airport use.
