感应过电压对输电线路耐雷水平的影响

Influence of the induced overvoltage on lightning resistance level of transmission line

对于室外架设的输电线路和电线杆等设施,雷电发生时产生的感应过电压所造成的输电线路问题不容忽视,而感应过电压现象的出现还会对输电线路的耐雷水平产生影响,造成长期损伤。文章从计算的角度分析了感应过电压对输电线路耐雷水平的影响情况,分析了感应过电压的影响因素,提出了感应过电压现象的控制办法,旨在提高输电线路的耐雷水平,降低感应过电压的影响。

For facilities such as transmission lines and utility poles erected outdoors,the transmission line problems caused by the induced overvoltage generated when lightning occurs cannot be ignored,and the appearance of the induced overvoltage phenomenon will also affect the lightning resistance level of the transmission line,causing long-term damage.This paper analyzes the influence of induced overvoltage on the lightning resistance level of transmission lines from the point of view of calculation,analyzes the influencing factors of induced overvoltage,and proposes a control method for the phenomenon of induced overvoltage,aiming at improving the lightning resistance level of transmission lines and reducing induced overvoltage.influence of voltage.
