摘要
介绍了分布式故障诊断装置的技术原理及功能特点。该装置利用分布式行波定位技术,在特高压输电线路遭受雷击、风偏、异物等影响发生故障跳闸时,能够诊断故障发生位置,帮助确定故障杆塔;同时通过分析故障电流波形,可判别故障类型,有效提升故障巡检工作效率和输电线路运维水平。
The technical principle and functional characteristics of distributed fault diagnosis device was introduced.Using distributed traveling wave location technology,the device could diagnose the fault location and help determining the fault tower when the UHV transmission line was tripped due to lightning stroke,wind deviation,foreign body and so on.At the same time,by analyzing the fault current waveform,the fault type could be distinguished,and the efficiency of fault inspection and maintenance level would be effectively improved.
