Analysis of the development of large capacity modular UPS market according to the construction of terminal building

The development of a new generation of information technology, such as large data, cloud computing and Internet of things, has pushed the airport to intelligent transformation and upgrading. Under the premise of ensuring information security, air traffic management, airline operation and management, airport operation management and other businesses gradually develop into “cloud data integration and innovative application”.
Power supply system from decentralization to centralization
The trouble of traditional decentralized power supply
As the core system of the infrastructure, the primary concern of the construction department of the Chongqing Jiangbei International Airport’s new terminal is the power supply system of the equipment. Once a power supply failure occurs, it will cause huge losses to the airport. The traditional power supply system uses distributed power supply, that is, one device corresponds to a small UPS. For example, the security channel, check-in, boarding, baggage and other original using decentralized 20-80kVA UPS power supply. Not only is it not convenient to disperse and maintain, but once it fails, it will be difficult for manufacturers to repair and maintain time, which will bring great trouble to airport electromechanical maintenance department. The distributed small UPS is inefficient, and most of the UPS efficiency of the present network is less than 90%, which can not meet the needs of energy saving and emission reduction at present.
Trend of centralized power supply system
The new terminal of the airport construction department, through the investigation of the existing scheme and after full discussion, decided to adopt the centralized power supply, to replace the original decentralized power supply system, the security channel, the original check-in, check-in, baggage and other scattered small capacity UPS power supply area with large capacity UPS centralized power supply. Considering the voltage loss and other problems, the power supply distance of the region can not exceed a certain range, and the UPS centralized power supply capacity is generally above 200kVA. Through the centralized power supply, the power supply efficiency of the system will be greatly improved and the index of energy saving and emission reduction can be realized. At the same time, centralized power supply also solves the problem of decentralized maintenance. The power supply is centralized, and the reliability of the system is higher. The 2N power supply system of power supply structure, redundant double bus system to improve the reliability of the power supply system, the fault of single equipment will not risk the system downtime.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
