摘要
高海拔、高雷电日地区电力线路,应根据具体情况有针对性地采取防雷击措施。分析了该地区某220kV线路的雷害情况以及雷击故障因素,提出了降低杆塔接地电阻、装设合理线路避雷器、加强线路绝缘配置等防雷措施,有效防止了线路雷害。
According to local condition,lightning protection measures are selected intentionally for lines in high altitude areas and on high lightning damage dates.Lightning damage and factors to lightning caused faults for a certain 220 kV lines of this area are analyzed.Lightning protection measures including decrease of tower grounding resistance,proper installation of lines arrester,increase of lines insulation coordination are provided.Those measures are effective to prevent the damage from lightning.
