摘 要:針對西北某省微地形區域近年來頻繁發生風害跳閘的情況,通過收集風偏、倒塔、異物短路等故障發生時的氣象條件、環境信息等,對該區域2010—2017年所發生的風害故障進行了統計分析,研究了各類型防風害措施的優缺點,并根據不同風害類型的特點提出有針對性防風害措施及建議,為輸電線路防風害工作提供參考。
關鍵詞:輸電線路;微地形;風害故障;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
