Five major technological innovations Schneider Electric leads the UPS industry to create more possibilities

october15,2018, Beijing, China today, three-phase medium and high-power UPS power supplies are widely used in major industries, especially in the data center and key power supply scenarios. As a global leader in digital transformation in the field of energy efficiency management and automation, Schneider Electric has already had an insight into the needs of customers in its long-term research and market promotion. It is committed to continuously improving the availability of three-phase medium and high-power ups and then eliminating the power supply from the following three aspects, leading a variety of new ideas and innovations. Among them, five major technological innovations are crucial to the development of the industry

first, the operation mode innovation of electrical transformation technology. In the early three-phase UPS system, the inverter priority operation mode (double conversion) and the later bypass priority operation mode (ECO mode) are often used, and the availability is low. Therefore, in order to achieve high availability, high operation efficiency and meet the load requirements, Schneider Electric developed a new mode in 2012 and obtained the patent super bypass priority operation mode (e conversion mode). The biggest advantage of this mode is that the current flowing through the power devices of rectifier and inverter is small, the fatigue aging of components is slight, and the service life is prolonged. Moreover, the inverter has been running in parallel all the time, and the system can switch the mode for 0ms. The overall efficiency 1. Clean, dehydrate and dry the recycled broken pieces of cross-linked PE cables and PE hollow blow molded products (the size of the broken pieces is 4 ⑺ mm); Also up to 98.8%, and the availability has been greatly improved

in fact, most industry users are still used to the traditional inverter priority operation mode, so the availability must be improved by improving the inverter. By studying the failure rate curve of power devices such as field effect graphene, a material tube which is stronger and tougher than carbon fiber, and IGBT, researchers realized that the inverter can be improved by reducing the pressure of power devices and selecting power devices with low voltage withstand value. Schneider Electric obtained the patent of four-level inverter technology in 2010, and found a reasonable balance between the withstand voltage value and level number of power devices. Its withstand voltage is 266v, far lower than 432V of power frequency machine, which not only improves the availability of inverter, but also improves the ups efficiency to 96.5%

in addition, with the development of large and super large data centers and semiconductor industries, high-power parallel systems with new physical architectures have emerged. The new physical architecture is different from the common electrical architecture of direct parallel operation of multiple ups. It not only simplifies the UPS system, reduces the external supporting distribution cabinets, switches and cables, but also has a public 1500kW static bypass, which is conducive to improving the availability of the UPS system to the copper based material industry convergence and development base of Tongling Economic and Technological Development Zone to double the output value in 2015. In addition, the parallel system with the new physical architecture adopts the modular design, which can increase or decrease the power cabinet according to the needs of users, and the flexibility and adaptability are improved. Schneider Electric first used the parallel physical architecture in 2003, and improved it in 2016 and applied it to VX series UPS products with a single system up to 1500kW n + 1

the next step is to improve the battery system. The traditional ordinary lead-acid battery is replaced about once a year. In the annual cycle of three-phase high-power UPS system, users spend more money on the battery system than the ups host. Driven by the electric power and energy storage industries, the cost of lithium batteries in 2018 has been reduced to 1 4 yuan/wh, which is almost the same as the price of ordinary lead-acid batteries. Therefore, the application of lithium batteries in data centers has become an important trend. The UPS products of Schneider Electric are truly compatible with lithium batteries. Compared with ordinary lead-acid batteries, lithium batteries have the characteristics of fast release, fast charge and low cycle life. This feature is especially suitable for the scenario of short delay discharge of high-power UPS system. It can also carry out multiple charge and discharge cycles every day to cooperate with peak valley pricing and reduce the operation cost of the whole system

the last thing worth mentioning is cloud services. As industry users attach great importance to the rapid recovery capability of high-power UPS systems, Schneider Electric has launched a new cloud service. The UPS system can be directly connected to Schneider Electric's cloud monitoring platform. Senior engineers who are familiar with the product are on duty for 24 hours. They can deal with the potential failure risk in advance, find the failure at the first time, quickly and accurately determine the fault location, and immediately mobilize internal spare parts and engineers to shorten the maintenance and recovery process to hours. The new cloud service has completely changed the after-sales maintenance mode and improved the system availability and maintainability

the improvement of electrical transformation technology, inverter and parallel system, as well as the innovation of battery system and cloud service, all mark the rapid development of three-phase medium and high-power UPS in the past decade. As an industry leader, Schneider Electric will continue to concentrate on research, further understand customer needs, continuously improve the availability, flexibility, adaptability and maintainability of three-phase medium and high-power UPS system in practice, and create more different possibilities
