摘　　要：阐述在电力电缆间歇性故障的状态监测中,采用SSTDR技术的电缆故障在线监测方法。以10kV交联聚乙烯电缆的状态监测为背景,建立了用于电缆故障分析的等效电路模型,探讨基于神经网络对电缆局部老化的诊断。实验结果表明,当电缆长度在100m以内时,检测率达到90%以上,诊断效果较好。This paper describes an online monitoring method for cable faults using SSTDR technology in the condition monitoring of intermittent faults in power cables.Based on the condition monitoring of 10kV cross-linked polyethylene cables,an equivalent circuit model for cable fault analysis is established,which discusses the diagnosis of local aging of cables based on neural networks.The experimental results show that when the cable length is within 100m,the detection rate reaches above 90%,and the diagnostic effect is good.
