Moistureproof and dehumidifying power distribution cabinet

Abstract

The invention discloses a moistureproof and dehumidifying power distribution cabinet. The power distribution cabinet comprises a cabinet body, a cabinet door and a power system arranged in the cabinetbody, the cabinet door is divided into two rotating plate structures with the same size; a heat exchange tube is embedded in each rotating plate structure; the top of the cabinet body is fixedly connected with a solar cell panel. A cavity is formed in the top wall of the cabinet body; the top of the cavity is fixedly connected with a conductive layer, the conductive layer is electrically connected with an impeller, the cavity is connected with a piezoelectric plate, the piezoelectric plate is electrically connected with a thermal conductive rod of a semiconductor structure through a conductive rod, the two ends of the thermal conductive rod are connected with the cabinet door and an insulating shell in the power system respectively, and the thermal conductive rod is made of thermoelectricmaterials. The power distribution cabinet has the advantages that when a large temperature difference occurs between the cabinet door and an insulating layer in a power system, an impeller rotates, on one hand, dry air is introduced, on the other hand, the temperature difference between the cabinet door and the insulating layer is reduced, and the insulating performance of the insulating layer isprevented from being reduced under the condensation effect.

Description

technical field [0001] The invention relates to the technical field of electric facilities, in particular to a moisture-proof and dehumidification power distribution cabinet. Background technique [0002] The power distribution cabinet is the collective name of the motor control center. It is generally divided into power distribution cabinets and lighting distribution cabinets in terms of categories. Among them, the metering cabinet is the final equipment of the power distribution system. The power distribution cabinet is used when the load is relatively scattered and the circuit is less When working, distribute the electric energy of a certain circuit of the upper level power distribution equipment to the nearby load and provide protection, monitoring and control for it. [0003] The power distribution cabinet is prone to moisture when it is in use. The main reason is that the internal contacts and electrical components of the electric cabinet will generate local heat when ...
