Abstract

The invention relates to the technical field of power distribution cabinets. The invention relates to a power distribution cabinet with a noise reduction structure, which comprises an inner frame. Theouter side of the inner frame is sleeved with an outer frame. Sound absorption plates are arranged on the inner wall of the outer frame and the outer wall of the inner frame; a sealing plate is arranged at an opening between the inner frame and the outer frame; a vacuum cavity is formed among the inner frame, the outer frame and the sealing plate; a leather plug is inserted into the surface of the outer frame; a sleeve is arranged on the surface of the outer frame; the outer side of the sleeve is sleeved with a protection head; and a finger clamping plate is arranged on the surface of the protection head. The power distribution cabinet with the noise reduction structure has the beneficial effects that the power distribution cabinet with the noise reduction structure adopts a double-layerframe structure, the two layers of sound absorption plates are additionally arranged in the cavity between the two frames, the sound absorption plates are prevented from being exposed to the outer side and damaged, the space between the two frames is vacuumized, the sound insulation effect of the frames is improved, and noise generated by working of electric devices in the power distribution cabinet is reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a noise reduction structure. Background technique [0002] The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively dispersed and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. Power distribution cabinet refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, mainly including high-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic Reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices, and high-volta...
