UPS is "uninterruptible power supply" in Chinese. The power ups is designed for substation, with rectifier and inverter as the main components and DC power supply system as the backup power supply, which provides constant voltage and constant frequency uninterrupted UPS power supply for the core equipment such as monitoring system, automatic instrument, remote communication and microcomputer system in substation. What are the common problems in the use of power inverters? How should the power inverter choose sine wave and pure sine wave? 1. The waveforms of the two are different, the pure wave is stable and equal to the commercial power, and the modified wave is analog commercial power. 2. The correction wave is generally a resistive load. The pure resistive load that works through resistive elements is called resistive load, such as mobile phones, computers, LCD TVs, induction cookers, white woven lamps, electric fans, rice cookers, electric fans, small printers, etc. 3. Pure wave is equivalent to mains power, which can carry any electrical appliance, and is generally used for carrying inductive load. Electrical appliances with coils are called inductive loads, such as motors, compressors, relays, LED lights, refrigerators, freezers, air conditioners, etc., whose power far exceeds the rated power (about 3-7 times) at the moment of startup. When the inverter is in use, what are the reasons for shutdown and alarm? 1) Whether the driven electrical power exceeds the rated power value of the inverter. 2) Whether the inverter is well connected with batteries and electrical appliances. 3) When the machine is stopped during use, whether it is a temperature alarm or not, it can continue to be used after being stopped for a period of time.
