本发明提供的电气柜内的防潮装置主要是利用PTC发热体和微电机风扇结合,向柜体内部吹热风,烘干电气柜内部因天气原因而粘附的水滴和潮气。相比现有的防潮装置,本申请中的防潮装置采用气体,更加均匀和柔和,烘干效果更好。送风口设置栅栏网能够阻挡安装箱内的部分灰尘进入柜体内部,从而影响柜体内部元器件的功能。热风出口设置栅栏网,同样有过滤灰尘的作用,也能够使热气分散均匀。安装箱设置于电气柜的外侧,不占用柜体内部的空间。设置罩壳和送风支管,不仅能够集中风力,而且能够将风力有效地送到不同的位置,防潮效果更好。汇集腔室能够集中风力,和喇叭状的出风部相配合能够增强热风出口的风力,快速赶走湿气,防潮效果更好。The moisture-proof device in the electrical cabinet provided by the present invention mainly utilizes the combination of the PTC heating element and the micro-motor fan to blow hot air to the inside of the cabinet to dry the water droplets and moisture adhered to the inside of the electrical cabinet due to the weather. Compared with the existing moisture-proof device, the moisture-proof device in this application uses gas, which is more uniform and soft, and has a better drying effect. The fence mesh at the air supply port can prevent part of the dust in the installation box from entering the inside of the cabinet, thus affecting the functions of the internal components of the cabinet. The hot air outlet is equipped with a fence net, which also has the effect of filtering dust and can also disperse the hot air evenly. The installation box is arranged on the outside of the electrical cabinet and does not occupy the space inside the cabinet. Setting the cover and the air supply branch pipe can not only concentrate the wind force, but also effectively send the wind force to different locations, and the moisture-proof effect is better. The converging chamber can concentrate the wind force, and cooperate with the trumpet-shaped air outlet to enhance the wind force at the hot air outlet, quickly drive away moisture, and have a better moisture-proof effect.
