摘要
输电线路是输送电力的“动脉”,各地区新建大量的输电线路工程,向用户提供更加完善、优质的电力服务,这对促进社会经济发展、提高人民群众生活质量、满足工业生产需要有重要的意义。但输电线路投运使用受到复杂环境、恶劣运行条件等因素影响,运行稳定性较差,相间短路、高阻、单相接地等故障问题时有出现,存在安全隐患。鉴于此,为保障输电线路运行安全,以输电线路在线监测、故障诊断作为切入点,详细阐述技术的实践应用方法,以供参考。
Transmission line is the“Artery”of power transmission,a large number of new transmission line projects in various regions to provide users with more perfect,high-quality power services,it is of great significance to promote social and economic development,improve people’s quality of life and meet the needs of industrial production.However,the operation of transmission lines is affected by complex environment,bad operating conditions and other factors,the operation stability is poor,inter-phase short circuit,high resistance,single-phase earthing fault problems occur from time to time,there are security risks.In view of this,in order to ensure the safety of transmission line operation,this paper takes on-line monitoring and fault diagnosis of transmission line as the cut-in point.
