Problems solved by technology

[0003] For this problem, the current method is to reduce the noise as much as possible by improving the insulation material between the silicon steel sheets and the sound absorption capacity of the transformer shell; however, the improvement in this area is limited by the existing materials and processes, and it cannot Obtaining superior results, at present, the noise near the transformer is still very loud, seriously disturbing the residents

Embodiment Construction

[0014] The present invention will be further explained below in conjunction with the drawings and embodiments:

[0015] in figure 1 In the illustrated embodiment, a housing 2 surrounding the transformer 1 is included. The housing 2 leads out a sound guide tube 3 which leads into a cellar 4.

[0016] Since the sound pipe 3 connects the housing 2 and the cellar 4, whenever the noise inside the housing 2 is reflected to the sound pipe 3, it will be guided into the cellar 4 along the sound pipe 3 without being reflected. The noise to the sound pipe 3 will eventually be reflected to the sound pipe 3 through multiple reflections from the inner wall of the housing 2 and finally be introduced into the cellar 4; of course, the noise that has been introduced into the cellar 4 may also be possible Through reflection, the sound guide tube 3 is guided back to the housing 2 again. However, since the mouth of the sound guide tube 3 has a very limited size relative to the walls of the cellar, the...

Abstract

The invention provides a noise reduction system of a power transformer. The noise reduction system of the power transformer comprises an outer shell which surrounds the transformer, wherein a noise leading pipe is led from the outer shell, and the noise leading pipe is communicated into a cellar. Preferentially, tuning forks are distributed in the noise leading pipe at internal along the pipeline axis, and the natural frequency of each tuning fork is 50HZ. The noise reduction system of the power transformer can eliminate noise of the transformer to a large extent, and improves the living environment of residents nearby the transformer.

Description

Technical field [0001] The present invention relates to the field of power facilities, in particular, to a transformer noise reduction system. Background technique [0002] Power transformer is a kind of basic equipment of power facilities, generally iron core transformer is used, and its power is very large. Since the iron core transformer obtains the voltage transformation effect through the alternating magnetic field, and the iron core of the transformer is stacked by silicon steel sheets, when the magnetic field in the iron core alternates at a frequency of 50 Hz, the silicon steel sheets are magnetostrictive As a result, continuous vibration will occur at a frequency of 50 Hz, resulting in a low noise, which seriously affects the daily life of residents around the transformer. [0003] For this problem, the current method is to reduce the noise as much as possible by improving the insulation material between the silicon steel sheets and improving the sound absorption capacity...
