摘要
社会经济的发展,我国的电力行业有了很大进展,电力电缆建设也在不断增加。电力电缆故障定位对维护电网安全稳定运行具有重要意义,是电力维护工作的关键环节。本文首先分析准备阶段措施,其次探讨电力电缆外护套及其故障原因,最后就电力电缆外护套的故障定位及监测技术进行研究,从而有效提高了配电电缆的安全稳定运行能力,满足了社会对电力安全可靠供应的需求,降低了用户的停电损失。
With the sustained growth of the social economy,China’s power industry has made significant progress,and power-cable infrastructure continues to expand.Accurate fault location in power cables is a critical link in power maintenance,directly safeguarding the secure and stable operation of the grid.This paper first analyzes preparatory-stage measures,then examines the outer sheath of power cables and its failure mechanisms,and finally investigates fault location and monitoring technologies for the outer sheath.The proposed approaches effectively enhance the safe and stable operation of distribution cables,meet society’s demand for reliable power supply,and reduce outage losses for end users.
