摘　　要：介绍了RCS - 915A型微机母线保护装置采用的反应工频变化量自适应加权式差动保护新原理的构成及其实现方法 ,并对装置在母线运行方式变化和各连接元件电流互感器变比不一致时能自动调整和具有母联死区保护等附加功能、保护装置现场应用中电流互感器极性检查方法、隔离开关位置报警时应采取的措施和母线运行方式发生变化时应注意的问题进行了阐述。It is mainly introduced in this article that the differential protection's new principle's configuration and appliance, and the principle, which is adopted by RCS-915A numerical busbar protection, is of response to operating frequency's change in adaptability and with additive right. And some other things about RCS-915A are also discussed in the paper, such as how it adjust automatically itself after that operation of busbar has changed or the transformation ratio of some connected elements to busbar are different from others, and it's additional function about protection in dead zone of busbar. In addition, the paper talked about how to check the transformation ratio of current transformer at work, and which way should be used when the isolating switch alarmed, and some problems which probably appeared after the operation of busbar has changed, and so on.
