| 摘 要： | 给出了基于随机地震动模型的高压断路器抗震可靠性分析方法。通过建立高压断路器及其隔震体系的有限元计算模型，分析了在断路器底部瓷套管根部加设叠层橡胶垫后的动力性能，分析中利用随机地震动模型，充分考虑地震动的随机作用，给出了四类场地土条件下结构的地震响应均值和标准差；利用一次二阶矩理论计算得到高压断路器的可靠度，给出了各场地土条件下的震害率曲线。结果表明不同场地土条件下隔震垫的减震效果有所差异。

| Abstract: | A seismic reliability analysis method is put forward based on the stochastic earthquake model in the paper. The dynamic performance of high voltage breaker with the layered rubber isolation is analysed. The mean and standard deviation of the seismic responses of the breaker under the different site conditions are gained based on the stochastic earthquake model. Then its seismic reliability is calculated by the FOSM, and the fragility curves of the breaker are built. The shock reduction effect of the isolation is different under the different site conditions. |
