Abstract

The invention discloses a noise reduction and elimination type box-type substation shell. The shell comprises an outer shell, a top cover, a supporting base and supporting legs, the top cover is fixedto the top of the outer shell, the supporting base is fixed to the bottom of the outer shell, heat dissipation holes are formed in the supporting base, the top cover and the supporting base enclose the outer shell into a closed box-type structure, and the supporting legs are fixed to the bottom end face of the supporting base; the outer shell is formed by sequentially connecting four wallboards,a movable door is connected to any wallboard, a sound absorption patch is bonded to the movable door, each wallboard comprises a sound attenuation layer, an electromagnetic shielding layer, a vacuum layer, a heat dissipation layer and an outer protection layer which are sequentially arranged from inside to outside, and the sound absorption layers, the electromagnetic shielding layers, the vacuum layers, the heat dissipation layers and the outer protection layers are fixedly connected with one another. The noise reduction and elimination type box-type substation shell is simple in structure, reasonable in design, high in overall structure compactness, good in sound insulation and noise reduction performance, high in heat dissipation efficiency, high in use safety and good in market application prospect.

Description

technical field [0001] The invention relates to the technical field of noise reduction devices for electric appliance casings, and more specifically relates to a noise-reducing and sound-absorbing box-type substation casing. Background technique [0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device, which are prefabricated indoor and outdoor compact power distribution equipment arranged in one according to a certain wiring scheme. Since the substation is equipped with high and low voltage switchgear, distribution transformers and other equipment, these equipment will emit noise during operation, especially the transformer, which generates extremely noise, and the noise of the transformer mainly comes from three sound sources: Cores, windings and coolers. The reason for the noise of the iron core is that under the action of the alternating magnetic field of the silicon steel sheet of the iron cor...
