Common power protection solutions for industrial UPS power systems

Commonly used power supply protection solutions for industrial UPS power supply systems. Commonly used power supply maintenance solutions for industrial UPS power supply systems. As the core of the industrial power supply system, UPS is the top priority of power maintenance. The automation and informatization of the modern industrial processing process are getting higher and higher, and higher and higher requirements are put forward for the reliability of the power supply. According to different load types, different types of UPS power products can be disassembled to ensure the reliability of the system. Due to the increase in automation, many modern industries use processing and control systems for processing. These systems can be powered by the same set of UPS as the fine industrial equipment, or can be powered by an independent UPS system. Since the processing system generally has no impact load, the load regulation requirements of the UPS are not high, and the intelligence of the UPS power supply (such as remote monitoring and other functions) is relatively high. 1. Stand-alone system application Stand-alone system is the most widely used processing method in the energy industry. According to the industrial UPS power supply planning, the stand-alone UPS host can maintain the system without power failure. When the AC load at each point of the single-point operation power supply method is independently maintained by the UPS, the non-stop maintenance is performed by switching to the manual maintenance bypass and exiting the operation of the temporary UPS power supply host. Manually repairing the bypass switch can carry out the switching process without continuous opening and closing, and will not cause the problem of continuous power supply load. On the host side, the non-continuous switching process between bypasses. 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 method takes into account the maintenance of the UPS host during the long-period operation of the equipment, and has great advantages compared with the single-system application method. During normal operation, all AC loads of the 1+1 parallel operation power supply method are evenly distributed by 2 UPS power supplies. Any UPS can run at 100% load for a long time. Therefore, the 1+1 parallel operation power supply method can be completely separated from a UPS host for maintenance. When the UPS needs to be repaired or maintained, the corresponding switches of the bypass cabinet and the output power distribution cabinet should be disconnected to completely isolate the UPS host equipment to be removed. 3.2N (dual bus) power supply system The application of 2N system is an AC intermittent power supply industrial UPS processing method that has been applied in recent years. Combining the characteristics of dual power supplies, the UPS power supply system supplies two completely independent UPS power supplies for the load. The power processing method deals with the single-point bottleneck failure risk between the UPS output terminal and the final load terminal. Two UPS dual outputs form a dual power supply method, which is currently the most typical 2N application method. Each UPS single system is a complete single operation method, and the maintenance and processing are also independent. Industrial UPS power supplies have strict application specifications. Only companies with high-power UPS technology and relevant industry application experience can meet the requirements of industrial power supply intermittent power supply system planning and processing. Industrial UPS power supply is specially designed for industrial use. Petroleum and natural gas: marine collection and transportation of petroleum products Power systems: power stations, power transmission, substation transportation: rail transportation, air transportation, marine water: sea water desalination, water treatment process and appearance control: inspection of chemical, mining, steel and paper mill And process control system The industrial UPS system adopts the latest 12 pulse rectifiers, brackets and the whole machine, and adopts three independent processor control systems. The reliability of the product has been greatly improved, and it is an outstanding representative of high-reliability UPS. Even the cooling fan is redundant planning. It is the top priority of high-reliability power supplies. In addition to industrial-grade UPS, many devices also use redundancy planning, which greatly improves the reliability of the product.
