| 摘 要： | 为了满足某些１１０ｋＶ线路式内故障时全线速动的要求，对原有ＬＦＰ－９４１型微机保护软件稍加移动，增加了顺序重合闸方式实现全线速动的功能，产生了ＬＦＰ－９４１Ｊ型保护，在１１０ｋＶ线路广泛使用微机保护的情况下，该项改进具有较大实用价值。

| Abstract: | This paper analyses the principle of the sequential reclosure and discusses its application to fast tripping for faults occurring at any point of series-connected 110 kV transmission lines. The above mentioned scheme has been accomplished by the advanced microcomputer-based protection LFP- 941J. |
