        摘 要:針對(duì)西北某省微地形區(qū)域近年來(lái)頻繁發(fā)生風(fēng)害跳閘的情況,通過(guò)收集風(fēng)偏、倒塔、異物短路等故障發(fā)生時(shí)的氣象條件、環(huán)境信息等,對(duì)該區(qū)域2010—2017年所發(fā)生的風(fēng)害故障進(jìn)行了統(tǒng)計(jì)分析,研究了各類型防風(fēng)害措施的優(yōu)缺點(diǎn),并根據(jù)不同風(fēng)害類型的特點(diǎn)提出有針對(duì)性防風(fēng)害措施及建議,為輸電線路防風(fēng)害工作提供參考。
        關(guān)鍵詞:輸電線路;微地形;風(fēng)害故障;防治措施

        Abstract: Aiming at the frequent occurrence of wind damage tripping in micro terrain region of certain northwest province in recent years, according to the collection of meteorological conditions and environmental messages when the faults such as windage yaw, surge tank and foreign short circuit etc happened, this paper carried out statistic analysis of wind damage faults happening from 2010 to 2017 in the region and studied on the relative merits of various types of wind damage prevention measures. According to the characteristics of different types of wind damages, this paper proposed the countermeasures for wind damage and suggestions, which provides references for the transmission line wind damage prevention work.
        Key words: transmission line; micro terrain; wind damage fault; prevention measures
