From presentation, transformer imposes impact to surrounding environment mostly in the form of noise jamming（Also even have ambient vibration to make
People does not feel like oneself）, for its administer 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 of so improvement is unsatisfactory, and not only cost is larger, and is related to equipment
Radiating, transform measure, therefore in engineering practice, its effect is often inconspicuous.
Dry-type distribution transformer vibration is one of its noise source and noise transmission path, draws currently for distribution transformer
Send out structural vibration to be less subject to pay attention to, from reduction vibration equipment to reduce the Synthetic science and engineering of its quadratic noise and structure borne noise
Journey practice is more rarely seen.
