摘要
介绍BORRI E2001型UPS装置长期运行中逆变器升压板上的电阻阻值发生漂移现象,导致UPS装置逆变器直流门坎整定值上升,分析了问题的危害性,提出了解决问题的预防措施。
The drift phenomenon of inverter resistance values leading to the increment of threshold setting value occurred during the long operation process of BORRI E2001 UPS is introduced in the paper,and the harmful consequences as well as the useful preventive measures are also proposed in detail.
