摘要
针对山区微波站屡屡发生的雷击而影响正常的通信电路，文章从雷电危害形成的原因和途径上阐述了直击雷危害、雷电反击危害、雷电感应危害、绕击雷和球形雷危害的范围和形式，并提出了这几种雷电方式的具体预防措施，经过对实践的总结和理论分析，说明有效的防雷措施必须是一个包括接地、均压、屏蔽、泄放4个方面的完整系统。
In view of the microwave station repeatedly struck by lightning in mountain areas, from the point of the forming and ways of lightning strikes, the scope and the form of straight lightning strike harm, counter-attack lightning harm, lightning induction harm and sphere lightning harm are elaborated in this paper, and several concrete ways of prevention measures are proposed. The practice and the theoretical analysis shows that the effective anti-lightning measures must be an entire system, which includes the earthing, voltage averaging, the shielding and discharging.
