Power distribution cabinet with dust removal device

Abstract

The invention provides a power distribution cabinet with a dust removal device. The power distribution cabinet comprises a cabinet, an electrical apparatus element is arranged in the cabinet body, suspended hoods are arranged at the upper end in the cabinet body and on the two sides in the cabinet body, the suspended hoods are connected to air draft fans through air pipes at the rear ends of the suspended hoods, filter screens are arranged in the air pipes, and dust recovery boxes are arranged on the filter screens. The suspended hoods are arranged in the cabinet body, the air draft fans are used for removing dust in the cabinet body, the situation that the dust is attached to a circuit to cause a short circuit is avoided, the interior and exterior of the cabinet body are detected through smoke and dust detectors, the air draft fans are automatically started to work, the working life of the power distribution cabinet in the working environment with a large amount of conductive dust is prolonged, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, and more specifically relates to a power distribution cabinet suitable for working environments with a lot of smoke and dust. Background technique [0002] Distribution cabinet, a box in which voltage appliances are placed. Collectively referred to as the power distribution center. They are centrally installed in the substation of the enterprise, and distribute the electric energy to the lower-level power distribution equipment in different locations. Because the power distribution cabinet needs to be used in various environments, and the dust in some environments is conductive, it is easy to short-circuit the circuit in the power distribution cabinet when it enters the interior of the power distribution cabinet, causing damage to the power distribution cabinet. At present, for the above situation, closed or explosion-proof electrical facilities are usually installed outside the power...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a power distribution cabinet suitable for a working environment with a lot of smoke and dust. The dust entering the power distribution cabinet is absorbed by the suction hood arranged inside the cabinet to prevent it from adhering to the power distribution cabinet. In the circuit, it solves the problem that the power distribution cabinet is not tightly protected against dust
