| 摘要: |
| 分析了常用的备用电源自投装置存在的无法判别是线路故障还是母线故障故造成母线失电的缺陷．提出了通过分析在母线失压前运行的进线电源的电流值是否大于最大负荷电流，判断是否为母线故障的解决方案。 |

| Abstract: |
| The normal automatic bus transfer equipment cannot determine the bus power loss is caused by line failure or bus failure,which is analyzed. A solution to it is presented,in which the entry line current before power cutoff is analyzed,if it is bigger than the maximum load current then the bus power loss is caused by bus failure. |
| Key words: automatic bus transfer,defect,solution |
