摘　　要：根据2014—2021年《中国电力年鉴》和各级政府电力部门官方网站资料,建立了全国变电站基础数据库。在损失评估研究模型中考虑了六氟化硫气体绝缘变电站以及敞开式空气绝缘变电站房屋建筑结构变化的影响。根据中国内地5个地区的六氟化硫气体绝缘变电站数量占比,建立其比例模型。基于六氟化硫气体绝缘变电站高压开关设备原型结构的模拟地震振动台试验以及汶川地震案例给出其经验易损性模型。根据中国内地4个地区的房屋建筑结构比例更新了敞开式空气绝缘变电站房屋建筑易损性模型,从而建立了新的地震损失研究模型。最后给出了中国内地地区以县(区)为单位的变电站在遭受Ⅶ~Ⅹ度地震破坏时的灾害损失、损失密度及损失比图。According to the China Electric Power Statistical Yearbook(2014-2021)and the data from the official websites of the electricity departments at all levels,a nationwide fundamental database of the transformer substations in Chinese mainland is established.The influence of the gas insulated substations and the variation of the substation s structure was involved in the damage assessment model.According to the proportion of the gas insulated substations in 5 regions in Chinese mainland,a model of the proportion of the nationwide gas insulated substations is established.Based on the simulated shaking table test of the high-voltage switchgear prototype structure of the gas insulated substation,and the results from the case study of the Wenchuan M S8.0 earthquake in 2008,an empirical vulnerability model of the gas insulated substation is given.Based on the proportions of the structure of the air insulated switchgear substations in 4 regions in Chinese mainland,the vulnerability model of the air insulated switchgear substations was updated,resulting in making a new assessment model of earthquake-caused losses.Finally,the earthquake-caused loss,the loss density and the loss ratio of the transformer substations subjected to the IntensityⅦ-Ⅹearthquakes in the counties and districts in Chinese mainland are given.
