| 摘 要： | 在变电站中，户外高压断路器的安装多采用细长的机座和支柱瓷套结构。由于外力作用、断路器的固有频率与地震频率接近．从而导致应力增大，断路器发生故障。现介绍国内外有关资料中，对断路器在外力作用下的支架、横梁和支柱瓷套等部位进行抗震动态应力的计算方法。

| Abstract: | Generally, installation of high voltage outdoor circuit breaker in power stations is based on slim support and supporting porcelain. Due to external force, the inherent frequency is quite near to earthquake frequency resulting in boosted stress and fault occurred in the circuit breaker. The paper introduces a calculation method for anti-earthquake dynamic stress on support, beam and supporting porcelain under external force in a circuit breaker. |
