1 概述
RCS-985RS/SS采用了高性能數(shù)字信號(hào)處理器DSP芯片為基礎(chǔ)的雙CPU硬件系統(tǒng)，裝
置有獨(dú)立的啟動(dòng)CPU作為整機(jī)起動(dòng)元件，該起動(dòng)元件在電子電路上（包括數(shù)據(jù)采集系統(tǒng)）
與保護(hù)CPU完全獨(dú)立，動(dòng)作后開(kāi)放保護(hù)裝置出口繼電器正電源。
RCS-985RS/SS適用于中小型汽輪發(fā)電機(jī)、水輪發(fā)電機(jī)、燃?xì)廨啺l(fā)電機(jī)等發(fā)電機(jī)機(jī)組，
并能滿(mǎn)足電廠自動(dòng)化系統(tǒng)的要求。
RCS-985RS/SS發(fā)電機(jī)保護(hù)根據(jù)相似保護(hù)功能分開(kāi)，相對(duì)獨(dú)立的原則，將主保護(hù)、后
備保護(hù)、異常運(yùn)行保護(hù)合理分配到兩個(gè)裝置中，共同提供一臺(tái)發(fā)電機(jī)所需要的全部電量
保護(hù)。

2 保護(hù)功能配置及典型配屏方案
對(duì)于一臺(tái)發(fā)電機(jī)，配置兩個(gè)獨(dú)立的保護(hù)裝置 RCS-985RS 和 RCS-985SS，每個(gè)裝置均
有獨(dú)立的出口跳閘回路。RCS-985RS 含有 3 路非電量保護(hù)，RCS-985SS 含有一個(gè)操作回
路（單跳圈或雙跳圈），非電量保護(hù)出口跳閘回路也完全獨(dú)立于電量保護(hù)。
