Abstract

The invention provides noise reduction equipment for a transformer. The noise reduction equipment for the transformer comprises a cover, a noise reduction material and the transformer, wherein the noise reduction material is arranged on the outer wall surface and / or the inner wall surface of the cover; and the cover covers the transformer. Because the cover covers the transformer and is provided with the noise reduction material, the noise reduction material absorbs noises, the noises generated by the transformer can be reduced effectively and are stored in the cover, noise transmission is avoided effectively, the working mute property of the transformer is improved, and noise pollution is reduced. Moreover, the noise reduction equipment for the transformer has the advantages of simple structure, convenience in operation and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of noise reduction equipment testing, in particular to a noise reduction equipment used for transformers. Background technique [0002] The noise of the distribution transformer is caused by the vibration of the iron core caused by the magnetostriction of the silicon steel sheet, and the electromagnetic attraction caused by the magnetic flux leakage between the joints of the silicon steel sheet and the laminations. [0003] At present, according to the characteristics of the transformer spectrum, noise transmission, attenuation, etc., the noise of the power distribution room is studied with transformers, transmission channels, sensitive points, etc. noise. [0004] In the noise reduction treatment of the power distribution room, the noise reduction materials are generally arranged around the transformer. Through the sound absorption and sound insulation of the noise reduction materials themselves, the rever...
