摘要
通过综合分析每一种故障选线方法的优缺点得出了如下结论:基于暂态信号的检测原理灵敏度远远高于基于稳态信号的检测原理;暂态信号检测法不仅适用于中性点不接地系统,而且适用于中性点经消弧线圈接地系统及间歇性电弧接地故障;随着微电子技术的发展,接地故障产生的暂态信号可以很容易地被记录并利用复杂的数字算法进行处理,所以暂态信号检测法必将得到越来越广泛的应用.
Several conclusions are obtained by synthetically analyzing all the single-phase earthed faulty feeder selection methods： firstly, detection methods using transient signals have better sensitivity than that using steady state signals; secondly, transient signal based detection methods are not only applicable for neutral isolated system, but also applicable for Peterson coiled systems and intermittent arc earthed faults. Lastly, with the developments of modern microelectronic techniques, the transient signals generated by single-phase earthed faults can be easily recorded and processed by complicated digital algorithms hence, transient signal based detection methods must be more applicable in.the future single-phase earthed faulty feeder selection devices.
