摘要：

Research on the characteristics of UHV negative lighting discharge process in tower-line air gap is of great significance to the lightning protection of UHV transmission lines. Based on the physical mechanism of negative discharge in long air gap, a simulation model of UHV negative lightning discharge is established. According to the UHV negative discharge model, the relationship between the development speed of the leader, lightning current wave front time, gap length and breakdown voltage in the physical process of lightning development is studied and analyzed. The analysis results discuss the influence of the development speed of the positive and negative polarity leader on the simulation calculation, and the relationship between wavefront time, gap length and breakdown voltage is obtained through fitting.
