Alternating-current low-voltage power distribution cabinet

Abstract

The invention discloses an alternating-current low-voltage power distribution cabinet. The cabinet comprises a cabinet body; the cabinet body is hinged to a cabinet door; a damping base is arranged atthe bottom end of the cabinet body; a vertical shaft is arranged at one corner of the upper part of the cabinet body; the vertical shaft is sleeved with a dust sweeping brush capable of swinging around the vertical shaft; a component chamber I is arranged at the upper part of the inner side of the cabinet body; a push-pull door is arranged at the opening end of the component chamber I; a component chamber II is arranged in the middle of the cabinet body; a plurality of vertical supporting frames are arranged in the component chamber II; a plurality of limiting holes are formed in the verticalsupporting frames; the vertical supporting frames are connected with a transverse supporting frame through bolts; the lower part of the transverse supporting frame is connected with an L-shaped component placing plate; a damp-proof room is arranged below the component room II; and an activated carbon adsorption net is placed in an interlayer of the damp-proof room. The cabinet has the advantagesthat the structure is compact, the anti-collision performance is good, the back design prevents the cabinet from being damaged due to collision with a foreign object in a carrying process, the cabinethas a drying function, the functions are relatively diversified, and the requirements of use can be met.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an AC low-voltage power distribution cabinet. Background technique [0002] The AC low-voltage power distribution cabinet is suitable for the power distribution system of power users such as power plants, substations, factories and mines with AC 50Hz, rated working voltage 380V, and rated working current up to 3150A, as power conversion, distribution and distribution of power, lighting and power distribution equipment. for control purposes. The AC low-voltage power distribution cabinet is a new type of low-voltage power distribution cabinet designed in accordance with the principles of safety, economy, rationality and reliability according to the requirements of the superior in charge of the Ministry of Energy and the majority of power users and design departments. The product has high breaking capacity and dynamic thermal stability. it is good. The electrical scheme is flex...

AI Technical Summary

Problems solved by technology

It can be used as a replacement product for low-voltage complete switchgear, installed and used indoors, and the altitude of the place of use can reach 2000m. However, in the existing technology, the general coefficient of the power distribution cabinet is relatively low, which directly leads to the construction efficiency. Not high, the anti-collision and moisture-proof performance of the power distribution cabinet shell is poor, and the components in the power distribution cabinet cannot be well protected, and most power distribution cabinets do not have a separate location for the cooling device, which is different from the electrical components Set together, easy to mess up and inconvenient to maintain
