Embodiment 1

[0047] like Figure 1-Figure 3As shown, the substation noise monitoring and noise reduction system includes a casing 1, the top of the casing 1 is provided with a top cover 2, at least one side wall of the casing 1 is provided with a soundproof door 7, and both the casing 1 and the top cover 2 are It is made of epoxy resin sound-absorbing board, which not only can soundproof, but also has the advantages of insulation. A plurality of sound-absorbing boards 3 are rotatably arranged on the inner side of the casing 1. The outer side wall of the sound-absorbing plate 3 is provided with an arc-shaped clamping plate 5, the arc-shaped clamping plate 5 is detachably arranged on the rotating shaft 4, the arc-shaped clamping plate 5 and the rotating shaft 4 are in clearance fit, and a plurality of sound-absorbing plates 3 are provided. It is two layers, the sound-absorbing panels 3 of the two layers are staggered, and there is an overlapping part between the two adjacent sound-absorbing ...

Embodiment 2

[0053] like Figure 1-Figure 3 As shown, this embodiment is based on Embodiment 1, and the sound-absorbing panel 3 is an arc-shaped panel concave toward the housing 1 .

Embodiment 3

[0055] like Figure 1-Figure 3 As shown, this embodiment is based on Embodiment 1, the fixed beam 10 is a hollow structure, and the inner side of the fixed beam 10 is filled with sound-absorbing columns 11; Sound-absorbing layer and electromagnetic shielding layer, the material of the sound-absorbing layer is glass wool or pearl cotton, and the material of the electromagnetic shielding layer is conductive rubber, EMI conductive foam lining material, metal EMI lining material or wave absorbing material.

[0056] In this embodiment, by setting the sound-absorbing column 11, the material of the sound-absorbing column 11 is glass wool or pearl cotton, which can improve the sound-absorbing effect of the top cover 2. The outer layer includes a sound-absorbing layer and an electromagnetic shielding layer in turn, which can make the electromagnetic field emitted by the inner coil of the transformer in the substation unable to penetrate and spread out, preventing the electromagnetic fi...

Abstract

The invention discloses a substation noise monitoring and noise reduction system and method. The substation noise monitoring and noise reduction system includes a casing, the top of the casing is provided with a top cover, and at least one side wall of the casing is provided with a soundproof door. The casing and The top cover is made of sound-insulating material, and the inner side of the shell is rotated with multiple sound-absorbing panels. The multiple sound-absorbing panels are arranged in two layers. There is an overlapping part between them, the sound-absorbing board is detachably arranged on the inner side of the shell; a plurality of sound-absorbing top plates are detachably arranged on the inside of the top cover, and a noise monitoring module is set on the outer wall of the shell and the top cover, and the noise The monitoring module is connected in communication with the controller, and the controller is connected in communication with the terminal. The invention solves the problem that the existing built-in sound-absorbing layer and sound-absorbing shell cannot partially replace the sound-absorbing material according to specific conditions, and cannot monitor to realize timely noise reduction.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a substation noise monitoring and noise reduction system and method. Background technique [0002] With the development of economy and the acceleration of urbanization, the electricity load in urban areas continues to increase, and there are more and more substations in urban areas, and the distance from residential buildings is getting closer and closer. High noise will affect nearby residents. [0003] There are more and more complaints about environmental pollution caused by transformer noise, and noise reduction treatment is required. The noise reduction methods used in substations mainly include setting sound-absorbing layers on the inner wall and top of the substation or setting up a shell with sound-absorbing function on the outside of the substation. Since the sound-absorbing materials used in the sound-absorbing layer have a certain service life, the n...
