摘要
介绍了零序电流和对地电场的计算在故障定位中的判据应用,在此基础上设计了一种具有在线监测和通信功能的新型故障指示终端。该故障指示终端分为采集单元和汇集单元两部分,对其结构做了详细的分析,并介绍了两者在配电线路的配置原则,采集单元将采集的数据及故障告警信息传送给汇集单元,汇集单元处理数据并通过GPRS通信方式将数据上传给监控中心,实现远程监控和智能故障自动定位。
This paper introduces the application of the zero sequence current and the calcand designs a new fault indication terminal witli on-line monitoring and communication functions. The fault indication termacquisition unit and collecting unit. And the princip)le of configuration of the two is introduced in the paper. The acquisition unit sends the col-lected data and fault alarm information to the collection unit. The data of t!ie collection unit are processed and uploaded to the monitoring center by GPRS communication, achieving remote moni tor ing and intel l igent faul t automat ic positioning.
