摘要

并联间隙作为一种疏导型的防雷方式

存在结构简单、安装方便、经济性好等诸多优点。传统的并联间隙由于有较大的短接距离

会导致雷击跳闸率的升高

且电弧发展路径具有不确定性。文中提出一种基于电弧运动特性和表面场强分析的新型并联间隙设计思路

并进行了仿真分析和验证性试验

结果表明该方法是可行的。

Abstract

As a distributary type of lightning protection

parallel gaps have simple structure

easy installation

good economy

and many other advantages. The traditional parallel gap due to the large short distance

can lead to lightning trip-out rate increases

and the arc movement path is uncertain. A new design of parallel gap design based on the characteristics of arc movement and surface field strength is proposed

and the simulation analysis and verification test are carried out. The results show that the method is feasible.
