From in presentation, transformator imposes impact mostly in the form of noise jamming to surrounding（Also it is even to have ambient vibration to make
People does not feel like oneself）, for its improvement often pay close attention to noise air borne, part power supply department frequently with traditional sound absorption, every
Sound measure carries out Noise Control, and the effect so administered is unsatisfactory, and not only cost is larger, and is related to equipment
Radiating, transform measure, therefore its effect is not often obvious in engineering practice.
Dry-type distribution transformer vibration is one of its noise source and noise transmission path, is drawn currently for distribution transformer
Send out structural vibration to be less subject to pay attention to, from reducing vibration equipment reducing the Synthetic science and engineering of its quadratic noise and structure borne noise
Journey practice is more rarely seen.
