Outdoor anti-condensation control cabinet

Abstract

The invention provides an outdoor anti-condensation control cabinet comprising a top shed which is arranged on a cabinet body, the cabinet body and ventilation windows which are arranged on two sides of the cabinet body. The bottom part of the cabinet body is provided with a heating device. The top shed adopts a double-layered top shed structure, wherein an upper top shed adopts a heat insulation material inclined top structure, and a lower top shed adopts a grid structure. The cabinet body is externally painted with light color scheme paint, and the internal wall is coated with paint with high hydrophobicity. The ventilation windows arranged on the two sides of the cabinet body are vertically arranged, and ventilation openings are provided with filter screens. The heating device adopts a constant heating type low-power heating element. Besides, a disconnection and shorting alarm device is installed. The control cabinet can withstand outdoor natural environment effects like sunshine, rain, snow, etc. A hot-pressing natural ventilation method is adopted, and a heater is arranged inside the control cabinet so that air temperature inside the cabinet is enhanced. Meanwhile, natural ventilation is additionally supplemented and external dry air is led into the cabinet so that air humidity inside the cabinet is reduced, condensation is avoided and electrical elements inside the cabinet are protected.

Description

technical field [0001] The invention relates to a control cabinet, in particular to an outdoor anti-condensation control cabinet. Background technique [0002] For equipment such as high-voltage circuit breakers and combined electrical appliances that operate outdoors, condensation will occur in the local control cabinet due to factors such as outdoor humidity and large temperature changes, which will lead to damage to the secondary components in the cabinet, short-circuit of the terminal block, and damage to the control cabinet itself. Corrosion of steel parts and other issues will pose hidden dangers to the safe operation of the main equipment. [0003] Patent application number 201220250203.2 in the prior art is an anti-condensation switchgear, which only has an exhaust window on the side of the cabinet, and the hot air rises with water vapor, and then condenses on the top of the cabinet, so there is no anti-condensation design on the top. The condensation device will no...
