摘要
文章对高压电缆运行过程中常见的缺陷和故障问题进行了阐述,对现行检测方法进行了分析和探讨,并提出基于频域阻抗谐振模型的高压电缆现场检测技术及故障快速定位方法。在某供电局实际应用证明,该方法有效缩短了高压电缆缺陷检测的时间,显著提高了电缆故障快速定位的能力,对高压电缆安全运行提供了重要的技术保障。
In this paper, the common defects and faults in the operation of high voltage cables are described, and the current detection methods are analyzed and discussed. A field detection technology and a fast fault location method for high voltage cables based on frequency domain impedance resonance model are proposed. The practical application in a power supply bureau proves that the method effectively shortens the time of defect detection of high voltage cables, significantly improves the ability of fast fault location of cables, and provides the important technical guarantee for the safe operation of high voltage cables.
