摘　　要：讨论了高压变电站１（１／２）电气主接线系统的抗震可靠性计算方法。针对这种接线形式的特 点，提出应当按网络系统计算系统的可靠性，并提出了３种可靠性分析准则，以计算系统的可靠性。实例分析表明，具有１（１／２）电气主接线系统的变电站，虽然各个电气设备的抗震可靠性不是很高，但 其主接线系统的抗震可靠性可以比单个设备的可靠性高得多。This paper discusses the analysis of seismic reliability of breaker-and-a-half configuration of high voltage substation. According to the characteristic of this kind of configuration, three kinds of conditions to analyze the reliability of electrical network of substation are given. The results of case studied show that the seismic reliability of break- er-and-a-half configuration is very high, though the reliability of each electrical equipment is not very high.
