南网同走廊多回线路运行维护措施研究

Research on Operation and Maintenance Measures of Multi-circuit Lines in Common Corridor of China Southern Power Grid

介绍了同走廊多回线路的定义,给出了南方电网500kV及以上电压等级交直流输电线路同走廊区段的分布情况。对雷击、污秽、覆冰、山火、外力破坏、地质灾害等常见同走廊多回线路风险隐患的排查及处理措施进行了探讨,提出了南网同走廊多回线路的运行维护措施,可为相关行业标准的制定提供参考。

The definition of Multi-circuit Transmission lines in common corridor was introduced and the detailed distribution of common corridor segment of 500kV and above AC/DC transmission line of China Southern Power Grid was provided.For lighting, dirty, ice coating, forest fire, force damage and geological disaster, investigation and treatment measures of hidden danger of common corridor were discussed. The operation and maintenance measures of multi-circuit lines in common corridor of China Southern Power Grid was proposed, which could provide reference to the development of relevant industry standard.
