摘要
架空输电线路受到雷击会对电力设备造成损伤,影响电力系统正常运行,因此加强架空输电线路防雷至关重要。对110 kV及以上高压架空输电线路雷击产生的原因进行分析,制定有效的防护措施以减少雷击跳闸事件,增强线路的耐雷性能,确保安全稳定供电。
Overhead transmission lines will be damaged by lightning strike,affect the normal operation of power system.Therefore,it is very important to strengthen lightning protection of overhead transmission lines.Therefore,it is necessary to analyze the causes of lightning strike on 110 kV and above high-voltage overhead transmission lines,and formulate effective protection measures to reduce lightning trip events,enhance the lightning resistance performance of lines,and ensure safe and stable power supply.
