摘　　要：雷击会造成牵引变电所停电,从而影响电气化铁路的运行。借鉴风险管理思想,提出牵引变电所雷击灾害风险评估的方法:通过确定变电所各部分雷击危险区的面积,考虑防护措施对雷击概率的影响,对雷击可能造成的损失进行风险评估。通过对铁路鹰厦线上某一牵引变电所进行的雷击灾害风险评估,验证了方法的可行性。Lightning often causes power failure in traction substation and thus affects the operation of electric rail- ways. A risk assessment method of lightning disaster is pro- posed in this paper for the traction substation by referring to the risk management concept. Through identifying vari- ous parts of lightning danger zone and fully considering the impact of protective measures on the lightning strike proba- bility, the risk assessment of lightning damage may be taken. An example of risk assessment of lightning damage for the traction substation on Yingtan-Xiamen Line is quo- ted to verify the feasibility of the method.
