摘要(Abstract)：
在微机型保护装置中,广泛采用计算软件实现主变压器纵差保护中某侧电流的移相,由此带来了差动TA二次接线极性的问题。简述了RCS-985主变压器比率差动保护的基本原理,对保护调试方法以及差动TA二次接线方式作了细致分析。
In microprocessor-based protection device,calculation software has been widely applied to achieve one side current phase shift for longitudinal differential protection of main transformer.It results in the problem of differential TA secondary connection polarity.This paper introduces the basic principles of RCS-985 main transformer percentage differential protection.The method of protection commissioning and differential TA secondary connection mode are analyzed in detail.
