摘要
并联间隙又称招弧角间隙或引弧角间隙,目前已被广泛地应用于输电线路防雷中。采用ATP软件对典型的220kV同塔双回杆塔建立了线路模型以及绝缘子先导闪络模型,在2~4个并联间隙的不同配置方案下,分别计算线路的单回及双回闪络耐雷水平,得到了最优配置方案。计算结果可作为同塔双回输电线路的防雷设计和运维的参考依据。
Parallel gap namely arcing horn gap is a common grooming type of lightning protection measures.The paper uses ATP simulation software to establish the typical tower structure model of 220 kV double circuit transmission line and insulator string flashover model,calculates the lightning withstand level of single loop and double-circuit line flashover with different parallel gap configuration options,and obtains the optimal configuration strategy.The results provide reference for the design and operation of double circuit transmission line.
