Problems solved by technology
[0003] However, in the existing metal-enclosed low-voltage power distribution cabinet, because the installation frame is set inside the switch cabinet, the field of view of the entire installation frame is poor, and the operating range of the staff is narrow, which makes it difficult for the staff to operate when installing or maintaining instruments and components on the installation frame. Uncomfortable, and some power distribution cabinets have sparks and spontaneous combustion due to the large number of internal components or excessive local temperature due to short circuit. If the fire cannot be extinguished in time, it is very easy to cause large economic losses or casualties

The invention relates to the field of power distribution cabinets, and particularly relates to a low-voltage power distribution cabinet. The low-voltage power distribution cabinet comprises a cabinetbody, an assembly framework, a dust removal mechanism and a cooling mechanism, wherein the cabinet body is divided into a power distribution chamber and a dedusting cooling chamber by a separator plate, the assembly framework used for installing a low-voltage power distribution element is installed in a power distribution room, the assembly framework slides back and forth through a driving mechanism installed in the power distribution room, and the dust removal mechanism and the cooling mechanism which are used for removing dust and cooling gas in the power distribution room are installed in the dedusting cooling chamber. The assembly framework in the low-voltage power distribution cabinet provided by the invention is high in openness, so that workers are facilitated to install or maintaininstruments and elements on the assembly framework conveniently; and meanwhile, when the low-voltage power distribution cabinet spontaneously combusts, an air bag is punctured, so that fire extinguishing gas leaks, the concentration of oxygen in the low-voltage power distribution cabinet is reduced, and the extinguishing efficiency of the fire extinguishing gas on flames and sparks is improved.
Description
Technical field [0001] The invention relates to the field of power distribution cabinets, in particular to a low-voltage power distribution cabinet. technical background [0002] The rated current of the low-voltage distribution cabinet is AC 50Hz, and the rated voltage is 380v, which is used for power conversion and control of power, lighting and distribution. This product has the characteristics of strong breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicability, novel structure, etc. The power distribution cabinet is a massive parameter in data, which generally requires the switchgear, measuring instruments, protective appliances and auxiliary equipment to be assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage power distribution cabinet. During normal operation, the circuit can be turned on or off by means of manual or automatic switch. The power distribution ca...
