Abstract

The invention provides a noise reduction device for a transformer, comprising: a cover body; a noise reduction material, the noise reduction material is arranged on the outer wall surface and / or the inner wall surface of the cover body; a transformer, and the cover body is arranged on the outside of the transformer . Since the cover is placed outside the transformer and the noise reduction material is provided on the cover, the noise generated by the transformer can be effectively reduced through the sound absorption of the noise reduction material, and the noise is contained in the cover, thereby effectively avoiding noise. Spread, improve the quietness of the transformer, and reduce the noise pollution. At the same time, the noise reduction device in the present invention also has the characteristics of simple structure, convenient 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...
