医院病房楼雷击风险评估

针对医院病房楼的特殊结构,用IEC62305-2《雷电灾害风险评估》的评估方法对其进行雷击风险评估。风险评估的结果显示,雷击风险主要来自雷击建筑物及相连线路造成的内部系统失效所引起的,需要采取三级浪涌保护,使人员伤亡损失R1风险值降低到容限值以下,并通过对经济损失R4的计算,得出该方案是经济合理的。

Lightning Risk Evaluation on Hospital Ward

Aiming at the special structure of the hospital ward, and its lightning risk was assessed using the method from IEC 62305-2 risk assessment for lightning disaster. The results showed that the lightning risk is mainly caused by system failure of the buildings and their connection lines when they are struck by lightning. It need to use 3 level SPD to decrease the casualties loss （R1 ） to an acceptable range, and calculate the economical rationality of the program by counting the economic loss （R4）.
