在汶川大地震中,变电站的大量电气设备受到了破坏.作为变电站的一种主要设备,断路器的抗震性能需要进行研究.根据地震中断路器的实际破坏情况,采用220 kV单极瓷柱式断路器的足尺寸真型试件进行了地震模拟振动台试验研究.通过测定其在不同地面运动输入作用下设备关键部位的加速度、位移、应变等主要参数,研究了此断路器设备结构的动力...
Many substation equipments were damaged during Wenchuan earthquake.The seismic behavior of circuit breaker,main component of substation,should be studied.In this paper,shake table tests on a real full size circuit breaker are carried out to study the seismic behavior of the equipment.Seismic responses of accelerations,displacements and the strains of the key parts of the equipment are measured under different ground motions with different levels of peak ground accelerations.These parameters are used to anal...
