Problems solved by technology

In addition, the environment of the test site is complex, and the instability of the microphone during installation and array movement will cause deviations in the position of the microphone. Therefore, it is necessary to control the test position of the microphone to ensure that the position of the microphone is accurate.

Abstract

The invention discloses an array for positioning and identifying a noise source of a transformer, comprising: a pair of vertically arranged support rods; a diamond-shaped telescopic mechanism arranged between the pair of support rods; The corners are respectively connected with a pair of support rods; the rhombus telescopic mechanism can slide up and down along the pair of support rods; the two ends of the telescopic rods are respectively connected to the other two opposite corners of the rhombus telescopic mechanism; the telescopic rods are parallel to the pair of support rods Setting; multiple sensors are installed equidistantly on the telescopic rod; when the distance between the pair of support rods increases, the rhombus telescopic mechanism drives the telescopic rod to compress; when the distance between the pair of support rods When it becomes smaller, the rhombus telescopic mechanism drives the telescopic rod to extend. The invention is convenient to assemble and disassemble, and is easy to carry.

Description

technical field [0001] The invention relates to the field of noise source location, in particular to an array for location and identification of transformer noise sources. Background technique [0002] At present, the noise emitted by the continuous operation of high-voltage, large-capacity large-scale power transformers has a serious impact on people's normal life and work. Therefore, it is necessary to locate and identify the noise source of the transformer, so as to take corresponding measures to achieve noise reduction. Due to the characteristics of transformer noise and the complexity of the test environment, it is necessary to test as close to the transformer as possible. Therefore, the near-field acoustic holography method is used to locate and identify the noise source. During the test process, due to the large number of transformers to be tested, the dimensions and specifications of each test surface are different, and the test plan (microphone spacing and test step...
