| 摘要: |
| 由于母线电压消失是备用电源自动投入装置最重要的启动条件，而母线PT断线会影响母线电压的采集，所以备自投设有母线PT断线检测功能，在发生母线PT断线时进行相应的处理。分析了现有的备自投中母线PT断线的判断处理方法，指出了其存在的缺陷，并提出了相应的解决措施。试验及实际运行表明这些措施是可靠有效的。 |

| Abstract: |
| The bus-bar voltage failure is the most important starting condition of the automatic back-up power supply device.The bus-bar PT-breaking may effect the voltage acquisition, so the most automatic back-up power supply device equipment the PT-breaking detection function. In this paper, the judgment and treatment methods of the existing automatic back-up power supply device is analyzed firstly. Then, it discusses the existing problems and gives the corresponding technology improvement measures. The test and running experience show that the improvement measures is effective and reliable. |
