摘　　要：本文针对同忻煤矿10kV变电所存在的接地故障查找不方便等现状,提出了利用暂态分析,配合多CPU构架的新装置改造方案,改造后无论是实接地还是瞬时接地故障的判断准确性都有了大幅的提高,该方案能够提供更多的采样数量和精度。因此,具有一定的实践性,也可以为类似变电所提供参考。This paper is aimed at overcoming the difficult in finding the ground fault in10 kV substation in Tongxin Coal Mine, and puts forward a new device reconstruction plan with the use of transient analysis and multi-cpu framework. After the reconstruction, the judgment accuracy of both real and instantaneous ground fault is improved greatly, which can provide more sampling quantity and precision.Therefore, it has certain practicality and can provide reference for similar substation.
