摘　　要：针对部分变压器差动保护装置提供的接线组别不能满足现场实际情况的问题,提出一种不同接线组别下通用的二次接线方法,可以在不改变变压器保护装置的基础上,通过改变二次接线端头标号及将极性端所有接线形式转化为12点接线或11点接线,满足现场可能出现的各种接线情况,具有普适性。Aiming at the problem that the wiring groups provided by some transformer differential protection devices cannot meet the needs in some substation,a general secondary wiring method under different wiring groups is proposed.This method can convert all wiring groups into 12-point wiring or 11-point wiring by changing the terminal label and polarity of the secondary wire without replacing the transformer protection device.It can meet various wiring conditions in substation and has universality.
