摘　　要：针对电力系统在历次地震中破坏的状态，通过对主要高压电气设备、高压变电站电气主接线系统、变电站系统以及电力网络系统的抗震可靠性分析计算，对电力系统地震灾害的特点进行了分析。在此基础之上，提出了提高电力系统抗震可靠性的措施和建议。In this paper, the characteristics of the damage of electric power system in previous earthquakes are discussed. According to the results of analysis and computing, the seismic reliability of high-voltage electrical equipments, high voltage substations and the high-voltage electric power network are discussed. On the basis of distinguishing features of the electric power system,some of reference suggestions on improving aseismatic capability are presented.
