Abstract
This paper discusses the operation mode, switching process and common fault and handling method of uninterruptible power supply (UPS). Firstly, elaborated the normal operation mode of uninterrupted power supply, including the basic principle and mechanism of stable power supply. Then, the process of automatic switching and manual switching of uninterruptible power supply is analyzed. These two switching modes both play a vital role in the power system and ensure the continuity and stability of the power supply. During automatic switching, UPS can quickly detect the main power failure and switch to the standby power supply, while the operator can adjust flexibly adjust according to the actual situation. In addition, the paper also deeply analyzes the common system faults and their causes, such as system resistance failure, capacitor failure and control board or drive board failure. These failures will not only affect the normal operation of the UPS, but also may cause damage to the power system and equipment. The corresponding treatment methods include direct observation method, phased stress test method and other special methods. These methods can help to quickly and accurately locate and solve problems, ensuring the stability and reliability of the uninterruptible power supply. The research of this paper can provide useful reference and guidance for the operation and maintenance of uninterrupted power supply in the power system.
