【摘要】 本文从唐山地震中少油断路器的实际震害出发,分析其破坏机理,建议采用迭层橡胶垫进行底部隔震,以提高它的抗震能力。本文还扼要介绍了断路器及其减震体系的振动台试验结果,并与理论计算进行了比较。试验和理论分析均表明用橡胶垫进行底部隔震有显著的减震效果,可以在实际工程中使用。更多还原

【Abstract】 In this paper, the destruction mechanism of circuit breakers (with not much oil) are analyzed, based on their damage field investigation during the Tangshan earthquake of July 28, 1976. The rubber cushion is proposed to be an element for shock isolating at the base. The vibratior test results of circuit breaker with vibration absorbing system(on vibration table)are presented and compared with those obtained by calculation. These results indicate that it is effective to use rubber cushion for shock isolating at the base.更多还原
