10kV配网的防雷技术与应用

Lightning Protection Technology and Application of 10kV Distribution Network

配电网的供电可靠性是生产生活中的一个重要指标,不但影响工业企业生产用电和居民生活用电,而且影响电能质量和社会效益。而雷雨天气跳闸率较高,每年雷击跳闸占10kV配电线路跳闸总次数的10%以上,影响了线路供电可靠性。基于此,本文针对目前的配电网系统,提出了相应的防雷措施,以期提供参考。

The power supply reliability of distribution network is an important indicator in production and life,which not only affects the electric power utilization for production of industrial enterprises and living of residents,but also affects the power quality and social benefits.However,the tripping operation rate is relatively higher in thunderstorm weather,and the annual tripping operation due to lightning stroke accounts for more than 10%of the total tripping operation times of 10kV distribution lines,which affects the reliability of line power supply.Based on this condition,this paper proposes corresponding lightning protection measures for the current distribution network system,for reference.
