The inner wall of the electrical cabinet 1 is provided with sound insulation cotton 11, and the sound insulation cotton 11 is used to block the propagation of internal noise of the electrical cabinet 1 to the outside.

[0024] The noise reduction sliders 5 are respectively connected to the outer arc surfaces of the guide columns 3 in a vertical sliding manner, and the noise reduction sliders 5 are respectively fixedly connected to the adjacent mounting plates 4. The noise reduction sliders 5 include a cylinder 51, a sliding disc 52, a sliding column 53, an air hole 54 and a sealing rubber pad 56. The cylinders 51 are respectively located on the left and right sides of the mounting plate 4. The interior of the cylinder 51 is horizontally slidably connected with the sliding disc 52. The outer arc surfaces of the sliding discs 52 are provided with sealing rubber pads 56. The sealing rubber pads 56 fit the inner arc surfaces of the cylinder 51. The sides of the sliding discs 52 close to the mounting plate 4 are provided with sliding columns 53. The sliding columns 53 respectively pass through the give-way holes on the surface of the cylinder 51 and are fixedly connected to the mounting plate 4. Air holes 54 are provided at both ends of the outer arc surface; the noise reduction slider 5 also includes a guide ring 57 and a rubber ring 58. The guide rings 57 are respectively arranged on the outer arc surface of the cylinder 51, and the inner arc surface of the guide ring 57 is provided with a rubber ring 58. The inner arc surface of the rubber ring 58 is respectively fitted with the outer arc surface of the guide column 3; the noise reduction slider 5 also includes a buffer spring 55, and the buffer spring 55 is respectively arranged between the side surface of the sliding disk 52 and the inner wall of the cylinder 51 to reduce the impact caused by the movement of the sliding disk 52.

[0025] The working principle of the utility model is as follows:

[0026] When the electrical cabinet is in use, the electrical cabinet is connected to the external power through the terminal block 6, and the circuit breaker 7 and the air switch 8 provide intelligent protection for the electrical circuit, and the circuit is disconnected in time when there is a problem with the electrical circuit; during the operation of the intelligent electrical cabinet, the sound insulation cotton 11 is used to block the propagation of the internal noise of the electrical cabinet 1 to the outside, and the filter 9 is used to filter out the noise signal and the interference signal, so as to automatically reduce the electromagnetic noise during the operation of the distribution cabinet;

[0027] At the same time, the mechanical vibration caused by the operation of the components of the power distribution cabinet will be transmitted through the sliding column 53, causing the sliding plate 52 to slide in the cylinder 51, pushing the air inside the cylinder 51 to be discharged from the air hole 54. Because the aperture of the air hole 54 is small, the speed of gas discharge is slow, causing the air pressure inside the cylinder 51 to change. The change in air pressure is used to block the left and right movement of the sliding plate 52, providing left and right shock absorption for the mounting plate 4;

[0028] At the same time, the mechanical vibration caused by the operation of the components of the distribution cabinet will be transmitted by the sliding column 53 and the cylinder 51, causing the guide ring 57 to slide on the outer arc surface of the guide column 3. During the sliding process of the guide ring 57, the rubber ring 58 contacts the conical arc surface of the conical ring 10. Under the top pressure of the conical ring 10, the rubber ring 58 is deformed. The greater the movement of the guide ring 57, the greater the deformation of the rubber ring 58, and the greater the friction force on the movement of the guide ring 57, which blocks the up and down movement of the guide ring 57, provides vertical shock absorption for the mounting plate 4, and reduces the transmission of vibration noise during the operation of the distribution cabinet from multiple directions.

[0029] It is worth noting that the circuit breaker 7, air switch 8 and filter 9 disclosed in the above embodiments can be freely configured according to the actual application scenario. The circuit breaker 7 can be a C80 model circuit breaker, the air switch 8 can be a DZ47-63A2P model air switch, and the filter 9 can be a FN431 model filter. The external controller controls the operation of the circuit breaker 7, the air switch 8 and the filter 9 using methods commonly used in the prior art.
