Document Type and Number:
WIPO Patent Application WO/2022/186448
Kind Code:
A1
Abstract:
The present invention provides a noise/vibration reduction device for transformers. An inner space (12) may be formed inside a tank (10) constituting the exterior of a transformer. A noise/vibration reduction device (20) may be installed on inner surfaces of tank side walls (14) constituting the outer surfaces of the tank (10). The reduction device (20) may include a plurality of support members (26, 28, 30) installed between a plurality of through-hole plates (32, 34, 36), whereby a first space (38), a second space (40), and a third space (42) may be formed between the through-hole plates (32, 34, 36) and the tank side walls (14). A first through-hole (32'), a second through-hole (34'), and a third through-hole (36') may be formed in the through-hole plates (32), (34), and (36), respectively. By varying a diameter (D) and a length (T) of the through holes (32', 34', 36') and a distance (L) between the respective through holes (32', 34', 36'), noise having different frequencies may be removed from each of the through-hole plates (32, 34, 36).
