摘要

低压脉冲法可以有效定位电缆中故障点，并对故障点类型做出判断。但是传统的低压脉冲法存在需要人为干预分离脉冲和无法直观确定故障点位置等问题，为解决该问题，本文首次提出将时间反演技术用于低压脉冲电缆故障定位。本文首先介绍了该方法的原理并阐述了相关计算步骤；然后通过仿真证明了该方法可以在无需人为识别脉冲的前提下有效确定电缆中的故障点，并对该故障进行类别辨识；最后在实验室中对105 m交联聚乙烯电缆制作局部缺陷，并用本文方法进行测试，实测结果证明了时间反演技术用于低压脉冲电缆故障定位的可行性和有效性。

Abstract

The low-voltage pulse method can effectively locate the fault in the cable and judge the type of the fault. The traditional low-voltage pulse method needs to separate the pulse artificially

and it is difficult to directly locate the fault in the cable. In order to solve this problem

the time reversal technology is introduced in low-voltage pulse method for locating the fault. Firstly

the principle of the proposed method is introduced and its calculation process are given. And then

the simulation results prove that the proposed method can effectively locate the fault in the cable and judge the type of the fault without human intervention. Finally

in the laboratory

the proposed method is tested in a 105 m XLPE cable with a local defect. The measurement results confirm the feasibility and effectiveness of the proposed method.
