AI Technical Summary
The noise of existing dry-type transformers mainly comes from magnetostriction and mechanical vibration. Existing passive noise reduction methods cannot effectively suppress noise generation and have poor noise reduction effects.
A dry-type transformer enclosure based on a damping structure is adopted. By setting a floating damping counterweight box and spring seat on the base, combined with buffer pads and elastic supports, vibration is passively absorbed twice and actively canceled once. The weight of the damping counterweight box can be adjusted to adapt to different transformer power.
It significantly attenuates vibration and noise transmission, reduces noise levels in building structures, and is adaptable to different transformer models and operating power.
