（9）滅磁斷路器選擇時需考慮發(fā)電機的強勵電壓、勵磁線圈的時間常數(shù)、放電電阻及斷開強勵電流的能力。
10.1.1 斷路器的作用
高壓斷路器在正常運行時用它接通或切斷負(fù)荷電流；
在電氣設(shè)備或線路發(fā)生短路故障或嚴(yán)重過負(fù)荷時，由繼電保護裝置控制其自動迅速地切斷故障電流，切斷發(fā)生短路故障的設(shè)備或線路，以防止擴大事故范圍。
10.1.2 斷路器的功能
斷路器開斷電路時，充分利用交流電弧電流每半周過零一次自然熄弧的特點，加強去游離使電弧不再復(fù)燃。其介質(zhì)強度恢復(fù)主要由斷路器滅弧裝置和介質(zhì)特性所決定。
系統(tǒng)電壓恢復(fù)過程可能是周期性的或非同期性的。取決于被開斷電路的參數(shù)。
