5) three-line parallelism
三线平行
6) parallel lines
平行线路
1.
Based on the safety of pilot zero sequence direction protection, the ground faults in parallel lines are discussed.
着眼于纵联零序方向保护的安全性,探讨了平行线路区内区外各种接地故障,研究发现,对于两侧均无电气联系的平行线路,纵联零序方向保护一定误动;对于一侧或者两侧有电气联系的线路(包括部分平行),是否误动取决于两者间联系是磁强于电还是电强于磁;对于一侧共母线的系统,此时纵联零序方向保护其实是安全的;对于同杆并架线路,纵联零序方向保护的安全性亦能得到保证。
