摘　　要：以曾多次遭雷击的某自动气象站为例,分析自动气象站雷击损坏原因,结论是直击雷防护方法不当、信号线缆未采取屏蔽措施、地电位不均衡;提出直击雷防护改造、增加线缆屏蔽和合理布置接地装置的防护措施。Based on the examples of certain automatic meteorological station damages caused by lightning stokes several times, the analyzed causes for damages from lightning stoke due to improper direct lightning stroke protection methods, absence of signal cable shielding measures, and non-equilibrium ground potential. This thesis also puts forward precautions including the reformation of direct lightning stroke protection, the addition of cable shielding measures and the appropriate arrangement of grounding devices.
