摘　　要：为开展电气机柜的地震概率安全分析(PSA),利用抗震能力与条件失效概率之间的关系和抗震鉴定试验数据,通过地震易损度的对数正态分布特性开展了电气机柜的概率易损度评价,得到某电气机柜的抗震能力中值为0.75g、随机性对数标准差为0.21、不确定性对数标准差为0.50及高置信度低失效概率(HCLPF)值为0.23g。该评价方法对电气设备的地震易损度分析具有借鉴作用。In order to carry out the probability fragility analysis(PSA), the probability fragility evaluation of a electrical cabinet qualified by testing was conducted based on the relationship between anti-seismic capacity of the component and the conditional failure probability, and also the lognormal characteristics of the fragility model. As a result, the median value of capacity(0.75 g), logarithmic standard deviation of random(0.21), logarithmic standard deviation of uncertainty(0.50) and high confidence and low probability failure(HCLPF) value(0.23 g) were obtained. The analysis method presented in this paper provides reference for successive seismic probability fragility analysis of electric equipment.
