摘要
广东地区的输电线路运行存在一些特殊问题,如雷电活动强烈、雷击跳闸率高,台风和强降水影响显著,线路防污形势严峻,电网密度大、同塔共架线路多等。文章分析了广东电网2006年110kV及以上输电线路运行情况,重点讨论线路防外力破坏、防雷、防污、掉线与掉串、合成绝缘子及电缆线路运行等几个方面的问题,提出了针对性的反事故措施。
There are some special problems.for power transmission line operation in Guangdong Power Grid, which is caused by influence of environment and climate, such as strong lightning activities, high ratio of lightning trip-out, typhoon and rainfall, serious situation of line anti-fouling, big density of power grid, multi-lines on the same tower etc.. The paper analyzed the operation condition of 110 kV and the above transmission lines in Guangdong Power Grid in 2006, discussed the problems in some aspects such as the line to guard against the damage of outside force, prevention of lightning faults, anti-fouling, operation of composite insulator and cable line, and put forward the measures for anti-fault.
