Vibration and noise reduction device of transformer

Abstract

The invention relates to a vibration and noise reduction device of a transformer. The vibration and noise reduction device comprises polyurethane buffers (1), intermediate partition plates (2), vibration reduction rubber pads (3) and C-shaped steel-channel frames (4) which are sequentially connected from bottom to top, wherein the polyurethane buffers (1) are fixedly connected with the ground, one side of an opening of each C-shaped steel-channel frame faces the vibration reduction rubber pads (3), the vibration reduction rubber pads (3) are embedded into the C-shaped steel-channel frames (4), and a transformer base is fixedly arranged on the other sides of the C-shaped steel-channel frames (4). Compared with the prior art, the vibration and noise reduction device has the advantages that dual vibration isolation modes are adopted, the mechanical vibration of the transformer is reduced, the influence of the vibration and the noise of the transformer on a surrounding environment is reduced, and meanwhile, the service lifetime of the transformer is also prolonged.

Description

technical field [0001] The invention relates to a noise reduction device, in particular to a transformer vibration reduction and noise reduction device. Background technique [0002] A transformer is a common electrical device, which generally includes a casing, an iron core, a coil and transformer oil arranged in the casing. With the increasing scale of urbanization in our country, the number of transformers and other power transmission and transformation equipment installed in urban and rural residential quarters and commercial areas is also increasing day by day, and most of the power transmission and transformation equipment such as transformers are directly placed in residential quarters or very close to the residence. place. However, the transformer is prone to the following problems during operation: 1. The transformer often produces serious environmental vibration and noise pollution problems during operation; noise. This directly affects the normal life of the re...

However, the transformer is prone to the following problems during operation: 1. The transformer often produces serious environmental vibration and noise pollution problems during operation; noise

However, the existing sound insulation cover or the vibration isolation material installed under the transformer foundation still has the disadvantages of unreliable structure and insufficient effect, and the method of reducing the magnetic flux density of the iron core will greatly increase the cost of the transformer, which is not economical.
