技术领域 technical field
本实用新型涉及一种避雷针，特别是一种安装在输电线路上的避雷针。 The utility model relates to a lightning rod, in particular to a lightning rod installed on a transmission line.
背景技术 Background technique
目前输电线路防雷方式众多，比如架设避雷线，使用避雷针，降低杆塔接地电阻等等，但是从这些技术的使用情况看，效果并不明显，电网的雷电跳闸率居高不下。雷电事故主要是由雷电绕击造成，尤其在山区，据统计，绕击雷电事故所占比例偏高，雷电绕击是由于屏蔽系统的引雷能力不够造成的。而目前电网采用的普通避雷针普遍存在引雷能力不足，不能高效防绕击的问题，而且目前的普通避雷针保 At present, there are many lightning protection methods for transmission lines, such as erecting lightning protection lines, using lightning rods, reducing the grounding resistance of towers, etc., but judging from the use of these technologies, the effect is not obvious, and the lightning trip rate of the power grid remains high. Lightning accidents are mainly caused by lightning shielding, especially in mountainous areas. According to statistics, the proportion of lightning shielding accidents is relatively high, and lightning shielding is caused by insufficient lightning induction ability of the shielding system. At present, the ordinary lightning rods used in the power grid generally have insufficient lightning guiding ability and cannot effectively prevent shielding, and the current ordinary lightning rods protect
护范围也较小。 The range of protection is also smaller.
