Analysis of the Potential Arc and Its Influencing Factors of Transmission Line

主要针对输电线路潜供电弧及影响因素进行分析。首先介绍了有关潜供电弧的基本概念及潜供电流特点;然后从理论的角度分析了特高压同塔多回输电线路的特点,同塔多回线路的特点均可能导致线路潜供电流增大,降低单相重合闸成功率;最后简单列举了其他影响潜供电弧熄灭的因素。

In this paper, the potential arc of transmission lines and its influencing factors are introduced. Firstly, the basic concept of the potential arc and the characteristics of the potential supply current are introduced. Then, the characteristics of the UHV transmission line on the same tower are analyzed theoretically. The characteristics of the muhi-circuit lines on the same tower may lead to the increase of the line potential , Reducing the success rate of single-phase reclosing. Finally, other factors that influence the extinguishment of the potential arc am briefly listed.
