摘要
通过仿真某实际智能变电站进线段遭受雷击时,研究不同雷击点对站内雷电侵入波过电压的影响以及主变压器安装避雷器的必要性。结果表明,在防雷措施一定的基础下,主变压器附近安装避雷器能够有效地降低变电站母线、主变压器的过电压值。
By simulating the impact of different lightning strike points on the lightning intruding wave overvoltage at the entry point of an actual intelligent substation and studying the necessity of installing lightning arresters for the main transformer, it is concluded that with certain lightning protection measures, arresters installed near the main transformer can effectively reduce the over-voltage of the substation bus and main transformer.
