摘要
通过对云南某供电区域多年的运行数据进行分析,发现配电变压器因雷击损坏的比例较高,为降低配电变压器的雷击故障率,保证用户的正常用电,重点从三方面进行了分析研究并采取配电变压器防雷击保护措施。
Through analyzing the data of Yunnan power supply area for many years, the result is that the power distribution transformer has a higher proportion of lightning damage. In order to reduce the lightning failure rate of the distribution transformer, the normal power supply of the user is guaranteed.
