【摘要】 为降低变压器噪声给人们工作和生活带来的影响,通过对合肥某小区地下室干式变压器分布情况的研究,得出变压器的振动通过地板,墙柱所产生的固体声是造成居民困扰的原因。通过对变压器进行主动隔振,大大降低变压器结构噪声的传播对居民的影响,并通过振动测量法对变压器隔振前后的振动情况进行对比,达到理想的效果。更多还原

【Abstract】 In order to reduce the dampening effect that transformer noise brings people,research dry-type transformer distribution in an underground chamber of a Hefei residential district and find that solid-borne noise transformer vibration generated through the floor and wall column is the arch-criminal that harass the district residents.Based on the vibration isolation to transformer,reduce greatly the structure noise of transformer.Through the vibration measurement method,make contrast analysis of before and after Vibration condition and achieve the desired effect.更多还原
