Abstract

The invention relates to a technique of decreasing the noise of transformers in transformer stations, in particular to a device for decreasing the noise emission of power transformers and a method thereof. The device comprises an elastic part (2) and a solid metal ball (3), the elastic part (2) is fixed on the surface of a transformer (1), and the solid metal ball (3) is fixed on the end of the elastic part (2). The device can convert the kinetic energy of the vibration of the transformer into elastic potential energy and thermal energy in order to reduce the energy of the vibration of the transformer, so that noise emission is decreased; moreover, the structure of the device is simple, the production cost is low, the device can be directly used on conventional transformers, transformers do not need to be altered, and mounting and maintenance costs are reduced as well.

Description

technical field [0001] The invention relates to a transformer noise reduction technology in a substation, in particular to a device and method for reducing the noise emission of a power transformer. Background technique [0002] The transformer in the substation is the main noise source of the power grid system. In order to reduce the noise emission of the transformer and avoid the sound pollution of the substation to the surrounding residents, the power grid enterprises invest a lot of money to treat it. After the noise reduction facilities are completed, there are many inconveniences to the daily operation and maintenance of the transformer. In order to reduce the noise emission of the transformer and reduce the investment, and facilitate the daily operation and maintenance of the transformer, the present invention is studied. Contents of the invention [0003] The purpose of the present invention is to provide a device and method for reducing the noise emission of power...
