試驗(yàn)概述編輯
繼電保護(hù)裝置是實(shí)現(xiàn)繼電保護(hù)功能的設(shè)備，就是指能反應(yīng)電力系統(tǒng)中電氣元件發(fā)生故障或不正常運(yùn)行狀態(tài)，并動(dòng)作于斷路器跳閘或發(fā)出信號(hào)的一種自動(dòng)裝置。它主要包含著下列主要的環(huán)節(jié)：①信號(hào)的采集，即測(cè)量環(huán)節(jié)；②信號(hào)的分析和處理環(huán)節(jié)；③判斷環(huán)節(jié)；④作用信號(hào)的輸出環(huán)節(jié)。
在電力系統(tǒng)中，如果一次系統(tǒng)*，而保護(hù)發(fā)生了誤動(dòng)，那么將影響對(duì)用戶(hù)的可靠供電，若重負(fù)荷線(xiàn)路發(fā)生誤動(dòng)跳閘，還有可能引起系統(tǒng)振蕩事故，破壞系統(tǒng)的安全穩(wěn)定運(yùn)行；如果一次系統(tǒng)發(fā)生了短路故障，但保護(hù)拒動(dòng)，將擴(kuò)大事故范圍，甚至損壞電力設(shè)備。為了使保護(hù)真正起到對(duì)電力系統(tǒng)的保護(hù)與控制作用，必須使保護(hù)整體處于良好的運(yùn)行狀態(tài)，使得各相關(guān)元件及設(shè)備特性?xún)?yōu)良、回路接線(xiàn)正確、定值及動(dòng)作特性正確。所以必須加強(qiáng)對(duì)保護(hù)的檢驗(yàn)質(zhì)量。
