| 摘 要： | 由于变压器中性点零序微机保护编程很灵活，因而，变压器中性点零序微机保护的电流互感器(TA)接线和整定的方式也很多．为此，分析变压器中性点零序微机保护各种接线的优缺点及其整定，强调变压器保护与系统保护配合时应注意的问题。最后介绍了变压器110kV侧旁路代路运行时的几种处理方法，以确保系统的安全运行。

| Abstract: | The programming for computer-based transformer neutral zero-sequence protection is very flexible, which diversifies the wiring and setting modes of current transformers of the protection. In this paper, the merits and demerits of various wiring modes and the setting of the protection are analyzed, matters needing attention in the cooperation between transformer protection and system protection stressed. At last, several treating methods for operating by-pass switches as transformer 110 kV-side switches are presented to ensure the safety of the system. |
