摘要
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 prob- lem 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.
