摘要;现有架空绝缘导线防雷击断线装置一般使用穿剌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。文中提出一种非穿刺型防雷击断线装置,分为带间隙和不带间隙2种类型.根据概率比较原则绝缘配合方法,分别设计出2种非穿刺式高压电极的最优安装位和间隙距离。
Abstract: The existing lightning protection and discomnection devices for overhead insulated conductors generally use piercing high-voltage electrodes for disconnection, which can easily lead to problems such as improper or excessive piercing, resulting in disconnection.'The article proposes a non piercing lightning proltection wire breakage device, which is divided into two types: with gaps and without gaps.Based on the principle of probability comparison, the optimal installation positions and gap distances for two types of non piercing high-voltage electrodes were designed for insulation coordination methods.
