线路型金属氧化物避雷器10年运行分析

作为全国较早在110kV及以上架空输电线路应用线路型金属氧化物避雷器（MOA）的单位之一，自1997年初开始与清华大学合作进行理论研究，并在110kV珠西线作试验挂网运行到现在已整10年。总结了线路型金属氧化物避雷器10年来的运行情况，通过分析其防雷效果，进一步证实了线路型避雷器在提高架空输电线路耐雷水平，有效降低线路的雷击跳闸率方面的效果是明显的，同时提出应用及运行方面的经验及注意事项。

Analysis on Operating of the Line Type's MOA in 10 Years Period

As the early applying unit of line type's MOA used in 110kV and above overhead line,since 1997 early it carried on theory studying with Qinghua University,and put 110kV Zhu-xi line as a testing to operation,it's 10 years long from it to now. Summing up the its operating condition in l0 years period and analysis its lightning-proof effect,furthermore approve,that it can be increased the level of lightning-proof and reduced tripping percentage by lightning strike,the effect is obvious,its application, experience in operation and proceeding to be attention are advanced in this paper.
