Abstract

The invention relates to a silencing device which is suitable for the technical field of electric power systems. The silencing device is arranged at a ventilation opening of a main transformer chamber of a transformer substation. The silencing device comprises a resistive silencing element and a reactive silencing element. The resistive silencing element and the reactive silencing element are arranged side by side, the reactive silencing element is close to the interior of the main transformer chamber of the transformer substation, and the resistive silencing element is far away from the interior of the main transformer chamber of the transformer substation; and the reactive silencing element comprises two perforated plate groups arranged side by side and a metal blind plate, each perforated plate group comprises a plurality of perforated plates arranged side by side, a resonant cavity exists between any two adjacent perforated plates, and the metal blind plate is arranged between the two perforated plate groups. The silencing device can reduce noise generated by the transformer and reduce the noise influence on residents.

Description

technical field [0001] The present application relates to the technical field of power systems, in particular to a noise reduction device. Background technique [0002] With the rapid development of my country's economy, the development of power system is becoming more and more perfect. There are more and more applications of transformers, so that transformers have become an indispensable part of the power system. During the normal operation of transformers, a lot of noise is usually generated, causing sound pollution and affecting the normal life of residents. [0003] In the traditional technology, it is usually used to improve the civil wall part of the main transformer room where the transformer is placed, so that it can meet the design requirements of sound insulation and noise reduction. [0004] However, the noise generated by the transformer will still be transmitted through the vents of the main transformer room, affecting the lives of residents. Contents of the...
