摘要
根据小电流接地系统发生单相接地故障后 ,各线路上零序电流间的动态平衡关系 ,建立选线判断依据。给出了 MLN98小电流系统接地选线装置的硬件、软件框图及使用效果。
After single phase earth fault occurs according to small current eart hed system,dynamic balence relation between zero sequence current in circuits,ju dgement basis of selecting lines is founded.Hardware and software block diagrams of the selected equipment of MLN98 small current earthed system effect are give n.
