摘要
电力设备遭受雷击是无法避免的。为降低雷击产生的过电压和过电流,以保护各类电子设备,阐述了如何为调度自动化系统规划雷电防护分区和确定雷电防护等级,以及如何将被保护设备分类,从而配置合适的浪涌保护器的具体方法。最后指出,只有采用综合防治,才能将雷害减少到最低限度。
Lightning strikes on electric power equipment are inevitable. To reduce the ensuing excessive voltage and current so as to safeguard the electronic equipment, this paper elaborates on the method about programming the thunderbolt shield subarea, determining the thunderbolt shield grade, sorting out the protected equipment and then configuring suitable surge protective device （SPD） for the dispatching automation system. It is concluded that lightning damage can only be minimized by taking comprehensive protective measures.
