Outdoor power distribution cabinet having cooling and dehumidification function

Abstract

The invention discloses an outdoor power distribution cabinet having a cooling and dehumidification function. The outdoor power distribution cabinet comprises a cabinet body and a cabinet door, wherein the cabinet body and the cabinet door are connected by a rotation shaft, an elastic sealing layer is arranged around the cabinet door and is arranged on the cabinet body in an embedment mode, an inverse V-shaped top cover is arranged at the top of the cabinet body, heat isolation layers are arranged on outer surfaces of the cabinet door and the cabinet body and the inverse V-shaped top cover, awaterproof support is connected to the bottom of the cabinet body, an isolation layer and a water absorption layer are sequentially laid in the bottom of the cabinet body from bottom to top, a temperature sensor, a humidity sensor and an air absorption hopper are arranged in the cabinet body, a pipeline connected with the air absorption hopper penetrates out of a side wall of the cabinet body, enters a cooling water tank and finally returns to the power distribution cabinet through the side wall of the cabinet body, a moisture absorption cavity, a drying cavity and a cooling cavity are sequentially arranged in the pipeline, the temperature sensor and the humidity sensor are used for detecting temperature and moisture in the cabinet, the moisture absorption cavity, the drying cavity and thecooling cavity are used for sequentially performing moisture absorption, drying and cooling on a gas, and the automatic cooling and dehumidification function of the power distribution cabinet is achieved.

Description

Technical field [0001] The present disclosure relates to an outdoor power distribution cabinet with cooling and dehumidification functions. Background technique [0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art. [0003] As an important part of the power system, the power distribution cabinet guarantees the continuity and safety of power supply due to its normal operation, so it plays an important role in modern industrial production and life. [0004] Existing large-scale power distribution cabinets are generally installed outdoors. Due to the rain and the erosion of outdoor humid air, not only will the life of the internal components of the power distribution cabinet be reduced, but also safety risks will be caused to the power distribution cabinet. In addition, because the outdoor power distribution cabinet is in the open air for a long time, under the influence of the exter...

AI Technical Summary

Problems solved by technology

[0004] Existing large power distribution cabinets are generally installed outdoors. Due to rain and outdoor humid air erosion, it will not only reduce the life of the internal components of the power distribution cabinet, but also cause safety hazards to the power distribution cabinet.

And because the outdoor power distribution cabinet is in the open air for a long time, under the influence of the external environment, especially in the case of direct sunlight in summer, the internal temperature of the power distribution cabinet rises sharply, coupled with the heat generated by the operation of internal devices, it is easy to cause the distribution The burning of components in the electric cabinet poses a safety hazard to the transmission of the entire power grid
