Uninterruptible power supply (UPS) is a load power protection device equipped with energy storage battery pack
UPS is a load power supply protection device equipped with energy storage battery pack, which can mainly solve the power network quality problems such as voltage surge, voltage spike, voltage transient, voltage drop, continuous overvoltage or undervoltage or even voltage interruption. According to the working mode, it can be divided into backup type and on-line type, and the On-line UPS power supply can be divided into on-line type and on-line interactive type. In addition, UPS is also divided into power frequency machine and high frequency machine according to working frequency; According to the shape, it is divided into three categories: tower type (vertical), rack type and modularization; It can be divided into outdoor and indoor types according to the use environment
UPS industry is now in its mature stage, and China’s market structure is further optimized
The concentration of China’s UPS industry has gradually increased with the continuous breakthrough of high-end product technology. The medium and low-end UPS has excess capacity and will intensify competition in the future, so as to speed up the clearing of the industry. At the same time, the leading suppliers in China’s UPS industry have also accelerated to shorten the gap with the international leading suppliers. According to the ups shipment in 2020, Shenzhen Kstar Science & Technology Co.Ltd(002518) has entered the top 5 global UPS power suppliers and ranked fifth and sixth in the three-phase ups and single-phase UPS markets respectively. The representative brands of international ups are Schneider Electric, Eaton, Emerson and other large enterprises, which have technical and brand advantages in high-end products. At the same time, they adopt the way of establishing production bases in China to increase their product competitiveness to maintain their market share of high-end products
UPS is mainly developing towards high frequency, high power, integration and modularization at this stage
UPS industry is developing towards green, energy saving and environmental protection. UPS is the main power electronics infrastructure in China’s information development and construction and new energy transformation and development. With the gradual implementation of China’s and even global green development strategy, UPS products are developing in the direction of energy conservation, low consumption and green environmental protection. At the technical level, UPS is developing towards intelligence, customization integration, high-power and modularization. Compared with traditional UPS, modular UPS has certain advantages in safety, reliability, energy saving and flexibility. I at the same time, modular design is conducive to the implementation of customized UPS scheme and can effectively reduce floor area and comprehensive cost
How to develop uninterruptible power supply (UPS) under the green and low-carbon strategy?
UPS power products first appeared in the late 1960s and were brought into China by Nixon’s visit to China in 1972. UPS was mainly used in the field of industrial manufacturing in the early stage. UPS products have experienced more than 40 years of development, and have been greatly improved in function width, reliability, energy consumption efficiency and so on. Under the green and low-carbon strategy, UPS intelligent digitization can optimize energy consumption management efficiency and improve power utilization with more refined management and control. At the same time, the modular design can flexibly expand and configure the system on demand to reduce energy consumption. With the rapid development of intelligent digitization, the amount of data increases explosively, and the demand for data storage and interactive data center also increases rapidly
