Abstract

The invention discloses a power distribution cabinet for a humid and dusty outdoor environment. The power distribution cabinet comprises a cabinet body, wherein a water tank is arranged at the bottom part of the cabinet body, is connected to a cold water main pipe through a water inlet pipe and is connected to a return water main pipe through a water outlet pipe; a serpentine cooling pipe is arranged in the water tank; an outlet end of the serpentine cooling pipe communicates with the cabinet body; a processing tank is arranged at the top end of the cabinet body; a cooling fan, a dust removal device and a drying device which are sequentially connected through a pipeline are arranged in the processing tank; an inlet end of the cooling fan communicates with the cabinet body; an outlet end of the drying device is connected to the inlet end of the serpentine cooling pipe; a controller is also arranged in the processing tank; a temperature sensor is arranged in the cabinet body; the temperature sensor and the cooling fan both are electrically connected with the controller; a humidity sensor is also arranged in the cabinet body; and the humidity sensor and the drying device both are electrically connected with the controller. The power distribution cabinet can normally work in the humid and dusty outdoor environment; and the application range is wide.

Description

technical field [0001] The invention relates to a power distribution cabinet, in particular to a power distribution cabinet used in humid and dusty outdoor environments. Background technique [0002] The electrical control system is inseparable from the power distribution cabinet, which accommodates various control switches and electrical components, realizing the centralized control and protection of the electrical system. The electrical components in the distribution box will continue to generate heat during the working process. If the heat dissipation of the distribution box is not good, the temperature in the distribution box will be too high, which will not only affect the normal operation of the electrical components in the distribution box, but also shorten the power distribution. The service life of the electrical components in the box, and sometimes it will cause the insulation aging of electrical coils and lead wires to cause breakdown, burnout, etc., especially in...
