| 摘要: |
| 通过对微机保护的重合闸逻辑回路进行分析,指出早期微机线路保护的重合闸逻辑存在的问题,并针对问题提出改进措施和注意事项。同时,在目前微机保护已被广泛采用的有利条件下,故障分析应充分利用微机保护中的事件记录,尤其是多个相关保护装置间事件记录的相互配合,从而作出全面客观的分析。 |

| Abstract: |
| Reclosing logic of some microcomputer-based relay protections are analyzed. Some pro-blems of early line protections are pointed out,and countermeasures and notices are presented. As the microcomputer-based relay protections have been widely applied,its event records should be fully used for fault analysis. Especially the mutual remedy of event records of multi relating protections helps for comprehensive and objective analysis. |
