摘要
安装线路避雷器已公认为线路防雷的有效措施。线路避雷器的产品结构包括有间隙避雷器及无间隙带脱离器的避雷器,指出了线路有间隙避雷器在绝缘配合、放电特性上存在一定问题。介绍了多家公司开发的线路无间隙(带脱离器)避雷器的安装结构,其降低过电压效果明显,并且线路无间隙避雷器必须是免维护的。
It is one of the most effective lightning protection measure to install line surge arrester. The product structure of line surge arrester contains line surge arrester with gaps and line surge arrester without gaps and with disconnector, and some questions are pointed out on insulation coordination and discharge characteristic of line surge arrester with gaps. The instrallation structures of line surge arrester without gaps and with disconnector developed by many company is introduced, the effect of decreasing over-voltage is obviously and the line surge arrester without gaps must be non-maintenance.
