Embodiment 1

[0047]Such asFigure 1-Figure 3As shown, the substation noise monitoring and noise reduction system includes a housing 1, a top cover 2 is provided on the top of the housing 1, at least one side wall of the housing 1 is provided with a soundproof door 7, and the housing 1 and the top cover 2 are both It is made of epoxy resin sound-absorbing board, which not only has the advantages of sound insulation, but also has the advantages of insulation. A plurality of sound-absorbing panels 3 are rotatably arranged on the inner side of the housing 1. Specifically, a rotating shaft 4 is arranged on the inner side of the housing 1. The outer side wall of the sound-absorbing board 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 arranged There are two layers, the two layers of sound-absorbi...

Embodiment 2

[0053]Such asFigure 1-Figure 3As shown, this embodiment is based on Embodiment 1, and the sound-absorbing board 3 is an arc-shaped board recessed toward the housing 1.

Embodiment 3

[0055]Such asFigure 1-Figure 3As shown, this embodiment is based on Embodiment 1. The fixed crossbeam 10 is a hollow structure, and the inner side of the fixed crossbeam 10 is filled with a sound-absorbing column 11; the sound-absorbing board 3 and the sound-absorbing top board 9 both include from the inside to the outside. The sound-absorbing layer and the electromagnetic shielding layer are made of glass wool or pearl cotton, and the material of the electromagnetic shielding layer is conductive rubber, EMI conductive foam lining, metal EMI lining 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. By combining the sound-absorbing board 3 and the sound-absorbing top board 9 The outer layer includes a sound-absorbing layer and an electromagnetic shielding layer in turn, which can make the electromagne...

Abstract

The invention discloses a transformer substation noise monitoring and noise reduction system and method. The transformer substation noise monitoring and noise reduction system comprises a shell, wherein the top of the shell is provided with a top cover, at least one side wall of the shell is provided with a sound insulation door, the shell and the top cover are both made of a sound insulation material, the inner side of the shell is rotatably provided with a plurality of sound absorption plates, the plurality of sound absorption plates are arranged into two layers, the two layers of sound absorption plates are arranged in a staggered mode, an overlapping part is arranged between every two adjacent sound absorption plates arranged in a staggered mode, the sound absorption plates are detachably arranged on the inner side of the shell, and a plurality of sound absorption top plates are detachably arranged on the inner side of the top cover; and the system further comprises noise monitoring modules are arranged on the outer shell and the outer wall of the top cover, the noise monitoring modules are in communication connection with a controller, and the controller is in communication connection with a terminal. The system solves the problems that an existing built-in sound absorption layer and an existing sound absorption shell cannot locally replace sound absorption materials according to specific conditions, and monitoring cannot be conducted to achieve timely noise reduction.

Description

Technical field[0001]The invention relates to the technical field of power facilities, in particular to a substation noise monitoring and noise reduction system and method.Background technique[0002]As the economy develops and the process of urbanization accelerates, the electricity load in urban areas continues to increase, and there are more and more substations in urban areas, and the distance to residential buildings is getting closer. The transformers in the substations will generate Higher noise has an impact on nearby residents.[0003]There are more and more environmental pollution complaints caused by the influence of transformer noise, and noise reduction treatment is required. The noise reduction methods used in the substation mainly include the installation of sound-absorbing layers on the inner wall and top of the substation or the outer shell of the substation with sound-absorbing functions. Because the sound-absorbing materials used in the sound-absorbing layer have a ce...
