【摘要】 高压隔离开关在分闸时,动触头撞击静触头致使设备产生剧烈振动。针对这种冲击产生的振动,提出了一种较为有效的方案——带有位移放大器的减振器,其中耗能弹簧采用具有超弹性和耐腐蚀的形状记忆合金。与已有方案比较,设计的减振器能取得显著的减振效果,改善设备的振动现象,减振效果明显。更多还原

【Abstract】 When the single arm pantograph A.C.H.V.disconnector is opening,because the moving contact impulses the stationary contact,the equipment vibrates violently.The paper presents a valid plan——a damper with displacement amplifier.The damper uses shape memory alloy as the reduction member.This damper can absorb shock obviously.The plan is proved to be effective by a real example.更多还原
