摘　　要：煤矿电网中性点非有效接地系统单相接地故障电流小且稳态特性不显著,检测难度大。为提升矿区内单相接地故障诊断效果,提出了一种利用5G传输的电缆绝缘监测方法。介绍了所提出的双端同步监测方法的结构和关键技术,以及在三相电缆模型上进行的仿真验证,分析讨论了该方法在实际测量中可能引起误差的因素。Single-phase grounding faults occurring in coal mine networks with ineffectively earthed neutrals have low fault current and insignificant steady-state characteristics,and thereby are hard to detect.Aiming at improving diagnosis effect of single-phase grounding faults in mining areas,a cable insulation monitoring method which utilizes 5G transmission is proposed in this paper.The structure and key technologies of the proposed dual-end synchronous monitoring method,as well as simulation verification carried out on a three-phase cable model,are described.The factors that may cause errors when applying the method to actual measurements are analyzed and discussed.
