Vibration isolation and noise reduction system of dry-type transformer

Abstract

The invention relates to a vibration isolation and noise reduction system of a dry-type transformer. A dry-type transformer body is elastically connected with the inner wall of a sound insulation box through first vibration reduction mechanisms and second vibration reduction mechanisms; each first vibration reduction mechanism comprises a fixed sleeve, a first telescopic rod, a first vibration reduction spring and a top seat, the first telescopic rod is fixedly connected with the fixed sleeve and the top seat, and the first telescopic rod is sleeved with the first vibration reduction spring; each second vibration reduction mechanism comprises a supporting bottom plate, a second telescopic rod, a second vibration reduction spring and a supporting top plate, the second telescopic rod is fixedly connected with the supporting bottom plate and the supporting top plate, and the second telescopic rod is sleeved with the second vibration reduction spring; the number of the first vibration reduction mechanisms and the number of the second vibration reduction mechanisms are both two. With the vibration isolation and noise reduction system of the dry-type transformer adopted, the technical problem that the vibration isolation and noise reduction effect is poor due to the fact that the operation means in the prior art is single, limited easily and lack of high efficiency can be solved.

Description

technical field [0001] The present application relates to the technical field of transformers, in particular to a vibration isolation and noise reduction system for dry-type transformers. Background technique [0002] During the working process of dry-type transformers, a lot of noise is likely to be generated due to various reasons, for example: 1. High voltage will cause over-excitation of dry-type transformers, and the sound will increase and sharp, which will directly and seriously affect the noise of dry-type transformers; 2. The resonance of the fan, casing, and other parts will produce noise, which is generally mistaken for the noise of the dry-type transformer; 3. Poor installation will aggravate the vibration of the dry-type transformer and increase the noise of the dry-type transformer; 4. The operating environment affects the dry-type transformer. Unfavorable environment will increase the noise of dry-type transformers by 3dB to 7dB; 5. The leakage magnetic field ...
