一种输电线路接地故障自动定位装置
摘要：
本发明涉及一种输电线路接地故障自动定位装置，所述输电线路连接在变电站主变压器出线侧，每条输电线路由三相总线构成，且每条输电线路上设有若干个节点，所述定位装置包括一连接在所述主变压器母线侧的信号源设备、若干个分别挂接在所述每条输电线路的每个节点处的每相总线上的故障显示器、若干个分别设置在所述每条输电线路的每个节点处的架空子站和一信息处理中心系统。本发明使运行人员能及时、准确地掌握输电线路的安全情况，节省抢修时间，提高工作效率，大大降低了线路故障所带来的经济损失和社会影响。
摘要（英）：

The invention relates to an automatic positioning device for grounding failure of a power transmission line. The power transmission line is connected with the outgoing wire side of a main transformer of a substation, respectively consists of a three-phase bus and is respectively provided with a plurality of nodes. The positioning device comprises a signal source device connected with the bus side of the main transformer, a plurality of failure displays respectively connected with each phase bus at each node of each power transmission line in a hanging way, a plurality of overhead sub-stations respectively arranged at each node of each power transmission line, and an information processing center system. By adopting the automatic positioning device, operators can promptly and accurately know the safety situation of power transmission lines, the repair time can be saved, the working efficiency can be increased, and the economic losses and social effects caused by line failure can be reduced greatly.
