摘要
根据设计规范对线路绕击跳闸率进行计算,计算过程中综合考虑风速的因素,并对考虑风速前后的计算结果进行比较分析,给出了大风区500 kV输电线路防雷击的措施.
In this paper,the trip-out rate with shielding failure was calculated according to the standard method.The calculation results of considering pre-and post-wind speed were analyzed and compared,and the mesures based on the aboved comparation were provided for 500 kV transmission lines in the area with gale to prevent lightning strikes.
