交流220 V不间断供电转换故障分析及对策

Analysis and Countermeasure of AC 220 V Uninterruptible Power Supply Conversion Failure

切换电源的过程会造成供电间断,不间断电源保证供电的连续性。这里介绍了一种交流220V不间断供电的转换装置,并为达成不间断供电的目的提供了两种工作模式。针对工程现场发生的掉电现象进行了波形监测。通过对实验波形进行分析与判断,提出掉电现象的原因与解决方法,并试验验证了解决方法的有效性。

The most important for the uninterruptible power supply is to ensure the continuity of the power supply. The process of switching the power supply will cause the power supply to be interrupted. A conversion device for AC 220 V uninterruptible power supply is introduced, and two working modes are provided for the purpose of achieving uninterrupted power supply. Waveform monitoring was carried out for power-down phenomenon occurring on the engineering site. Through analyzing and judging the experimental waveforms, the cause and solution of power-down phenomenon are proposed, and the effectiveness of the solution is verified with tests.
