摘要
文章旨在提升电力电缆的使用安全性和稳定性.通过总结电缆的常见故障和成因,采用了阻抗法和行波法两种故障定位技术,对电缆芯线故障进行了分析,比较了这两种方法的优缺点.结果表明行波法在故障定位的精确度和适用性方面,尤其在长距离电缆故障定位中,优于阻抗法.行波法能更有效地定位故障点,减少故障诊断时间.采用适当的故障定位技术可显著提高电缆故障的诊断精度,从而增强电缆的运行安全性和稳定性.推广行波法的应用能够为电力系统的维护提供更为可靠的支持,促进电力行业的长期稳定发展.
Abstract
Cables are important components in the power system,undertaking the important task of transmitting electrical energy.however,due to various factors such as design,aging,and external damage,cables are prone to various faults during use.in order to improve the safety and stability of cable usage,this study combines past experience to summarize common faults and their causes in power cables.based on this,two fault location methods,impedance method and traveling wave method,are proposed and analyzed.The advantages and disadvantages of these two methods are analyzed.Finally,taking cable core wire faults as an example,the precise diagnosis and location methods of cable faults are studied in order to facilitate this study,promote the long-term stable development of the power industry.
