摘　　要：随着电力系统向高效、智能化方向发展,输电电缆避雷器的稳定运行成为保障电网安全的关键,但环境因素、雷电冲击以及过负荷运行是导致其故障的主要原因。鉴于此,基于对输电电缆避雷器运行故障的深入分析,探讨在新形势下加强运行状态监测的必要性和价值,全面分析明确监测指标、系统设计及监测效果,提出一套完善的避雷器状态监测和故障预警系统,以为提高输电电缆避雷器运行效率和电网整体安全性奠定一定理论基础。With the development of the power system towards high efficiency and intelligence,the stable operation of transmission cable lightning arresters has become the key to ensuring the safety of the power grid.However,environmental factors,lightning strikes,and overload operation are the main causes of their failures.In view of this,based on in-depth analysis of the operational faults of transmission cable lightning arresters,this paper explores the necessity and value of strengthening operational status monitoring in the new situation,comprehensively analyzes and clarifies monitoring indicators,system design,and monitoring effects,and proposes a comprehensive lightning arrester status monitoring and fault warning system to lay a theoretical foundation for improving the operational efficiency of transmission cable lightning arresters and the overall safety of the power grid.
