摘要：Structural vibration and noise of indoor substation is getting more and more extensive attention. The 110kV urban indoor substation and its associated building are taken as the research object. The vibration and noise signal of testing points are acquired in the building and transformer room. Time domain analysis and frequency analysis for the test data are carried out. By test and analysis, vibration and noise characteristics are obtained. The transformer vibration and its noise were transmitted with obvious attenuation in the structural floor slab. The vibration transmission into the lower floor slab is higher than that of into the higher one. If the floor is far from the transformer room, the vibration and noise and the low frequency characteristic are weak and thus the attenuation is no longer significant. It is necessary that indoor substation equipment of vibration and noise transmission can be controlled.
