    Scheme of Avoiding Override Trip in Mine Underground

      摘要
    • 摘要: 根据煤矿井下供电系统的实际情况,提出了一种基于电流纵联差动保护原理的防越级跳闸方案,能够很好的满足井下对可靠性、安全性和连续性的要求。

       

      Abstract: According to the actual situation of mine underground power supply system,this paper proposes a new scheme to avoid override trip based on the current longitudinal differential protection,which can fulfill the requirements of reliability,safety and continuity in underground well.
