摘　　要：目前的架空绝缘导线防雷击断线装置一般使用穿刺式高压电极进行断线,容易出现穿刺不当或过多穿刺而造成断线等问题。文章提出一种新型无间隙式防雷击断线装置,该装置由避雷器和非穿刺式高压电极组成。由于高压电极非穿刺设计、绝缘导线放电点定位不确定,根据概率比较原则绝缘配合方法设计出非穿刺式高压电极最佳位置。本实用新型的防雷击断线装置能在不损坏架空绝缘导线的情况下有效地屏蔽短路电弧,从而避免了架空绝缘导线断线事故的发生。The existing overhead insulated conductor lightning strike disconnection prevention device generally uses piercing high-voltage electrode for disconnection,which is prone to problems such as improper piercing or too much piercing and causing disconnection.The paper proposes a new type of gapless lightning breakage prevention device,which includes lightning arrester and non-punctured high-voltage electrode.Due to the non-puncture design of the high-voltage electrode,insulated conductor discharge point positioning uncertainty,according to the probability comparison principle insulation with the method to design the non-puncture high-voltage electrode optimal installation position.The utility model of lightning strike disconnection device can effectively shield the short-circuit arc without damaging the overhead insulated conductor,thus avoiding the occurrence of overhead insulated conductor disconnection accidents.
