Noise reduction and shock absorption device of transformer

Abstract

The invention relates to the technical field of transformer noise reduction and shock absorption, in particular to a transformer noise reduction and shock absorption device which comprises a shell and a door plank, the front end of the shell is rotationally connected with the door plank, and the shell comprises a rectangular box, first sound absorption sponge, a sound transmission plate, a fixing column, a cylindrical spring, a guide column, a supporting plate, a rubber plate and an extrusion block. Through cooperation of the shell and the door plate, the transformer is positioned, when the transformer works, vibration generated when the transformer works is buffered so as to achieve the purpose of noise reduction and shock absorption, vibration force is decomposed while buffering is conducted, vibration borne by the shell is reduced, the service life of the shell is prolonged, and the shock absorption effect of the shell is improved; meanwhile, noise generated when the transformer works is absorbed, the noise generated when the transformer works is reduced, and in the noise reduction process, the noise makes contact with a sound absorption part and is absorbed by means of the reflection principle.

Description

technical field [0001] The invention relates to the technical field of noise reduction and vibration reduction of transformers, in particular to a noise reduction and vibration reduction device of a transformer. Background technique [0002] Transformer is a static electrical equipment used to transform AC voltage and current and transmit AC power. Its working principle is to change the voltage through the electromagnetic induction of the primary coil and the attached coil. It can change the voltage, the current, and the Impedance can be changed, so it is widely used in grid construction. [0003] The transformer will vibrate during use, and the vibration will generate large noise. Therefore, it is necessary to carry out noise reduction and shock absorption treatment on the transformer. The traditional shock absorption method is to buffer the vibrating transformer through buffer parts. Frequent vibration causes buffering. The life of the parts is reduced by frequent stress,...

[0003] The transformer will vibrate during use, and it will generate a lot of noise when vibrating. Therefore, it is necessary to reduce the noise and shock of the transformer. The traditional shock absorption method is to buffer the vibrating transformer through buffer parts. Frequent vibration leads to buffering. Part life is reduced due to frequent stress and will reduce the cushioning effect of cushioning parts
