线路型金属氧化物避雷器10年运行分析

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

作为全国较早在10kV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。

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 10 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.
