　　Commonly used power protection solutions for industrial 18650 li-ion battery systems

　　Power protection solutions commonly used in industrial 18650 li-ion battery systems. As the center of the industrial power supply system, UPS is the top priority for power protection. The production process of modern industry is becoming more and more automated and informatized, which brings higher and higher requirements for power supply reliability. Depending on the load type, different types of 18650 li-ion battery products can be configured to improve system reliability.

　　Commonly used power protection solutions for industrial 18650 li-ion battery systems

　　Due to the continuous improvement of automation, modern industry uses a large number of production process management and control systems. For the power supply of these systems, you can choose to use the same UPS system as precision industrial equipment, or you can choose to use an independent UPS system. Since the production process management system generally does not have impact loads, the load capacity of the UPS is not high, but the intelligence of the 18650 li-ion battery supply (such as remote monitoring and other functions) is relatively high.

　　Commonly used power protection solutions for typical industrial 18650 li-ion battery systems include stand-alone systems, parallel systems, and 2N (double busbar) power supply systems. How to choose a suitable 18650 li-ion battery supply solution depends on the characteristics and importance of the load carried by the system. For equipment that can be planned to be interrupted or stopped during operation, you can choose a single power supply; for important single power supply loads that cannot be powered off during operation, choose parallel power supply; for loads that can be connected to two 18650 li-ion battery supplies, 2N (dual power supply) is preferred. bus) power supply scheme.

　　1. Application of stand-alone system

　　The stand-alone system is the most widely used solution in the energy industry. According to the design of industrial-grade 18650 li-ion battery supply, running the UPS host body on a stand-alone machine can perform non-power outage maintenance of the system. In the stand-alone operation power supply scheme, each AC load is independently powered by a UPS. Non-power-off maintenance is performed by switching to manual maintenance bypass and exiting the running 18650 li-ion battery supply host. Manual maintenance bypass switching can carry out an uninterrupted "first on and then off" switching process, which will not cause the problem of power supply interruption to the load. Realize the seamless switching process between the host and bypass.

　　2. Application of parallel system

　　With the application of large-scale control systems in the energy industry, industrial UPS parallel systems have been widely used. This solution takes into account the maintenance of the UPS host during the long-term operation of the device, and has great advantages over the application solution of a stand-alone system.

　　During normal operation, all AC loads of the 1+1 parallel operation power supply solution are equally shared by two 18650 li-ion battery supplies, and any UPS can work with 100% load for a long time. Therefore, the 1+1 parallel operation power supply solution can completely withdraw one UPS host for maintenance. When it is necessary to inspect or maintain one of the UPSs, disconnect the corresponding switches of the bypass cabinet and the output distribution cabinet to completely isolate the UPS host device to be exited.

　　Application of 3.2N (double busbar) power supply system

　　The 2N system application is an AC uninterruptible power supply industrial UPS solution that has been applied in recent years. Combined with the characteristics of dual power supplies, the 18650 li-ion battery system provides two completely independent 18650 li-ion battery supplies for the load. This power supply solution solves the hidden danger of "single point bottleneck" failure between the UPS output end and the final load end.

　　Two UPS dual-channel outputs form a dual-channel power supply solution, which is currently the most typical 2N application solution. Each UPS stand-alone system is a complete stand-alone operation mode, which brings independent maintenance and management.

　　Industrial 18650 li-ion battery supplies have strict usage specifications. Only companies with high-power UPS technology and corresponding industrial application experience can meet the design and production requirements of industrial power uninterruptible power supply systems. Industrial-grade 18650 li-ion battery supplies are specially designed for industrial use environments:

　　Oil and Gas: Offshore collection of petroleum products, transportation pipelines

　　Power systems: power stations, power transmission, substations

　　Transportation: rail transportation, air transportation and ocean transportation systems

　　Water services: desalination, water treatment

　　Process and instrument control: Inspection and process control systems for chemical plants, mining, steel mills, and paper mills

　　The industrial UPS system adopts the latest 12-pulse rectifier, supports parallel operation, and adopts three independent processor control systems, which greatly improves product reliability and is an outstanding representative of high-reliability UPS. Even the cooling fan is redundant. It is the first choice for high reliability power supply. In addition to being designed according to industrial-grade markings, industrial-grade UPS also adopts a redundant design for a large number of devices, which greatly improves the reliability of the product.
