Power distribution cabinet with good preheating effect

Abstract

The invention discloses a power distribution cabinet with a good preheating effect. The cabinet comprises an outer cabinet; fixing buckles are fixedly connected onto two sides of the outer cabinet; vent holes are formed in one side of the outer cabinet; a dustproof net is arranged on the surface of the vent holes; a fan is fixedly installed on the other side of the outer cabinet; a connection component is fixedly connected inside the outer cabinet; one end of the connection component is fixedly connected with an inner cabinet; and the surface of the inner cabinet is movably connected with a cabinet door. According to the power distribution cabinet with the good preheating effect, a refrigerator, a drying box, a conveying pipe, air exhaust holes, and an air inlet are adopted; the effect ofthe refrigerator, the air inlet introduces hot air inside the inner cabinet; the hot air is cooled by the refrigerator and thereafter is dried through the drying box; the dried air is discharged through the conveying pipe and the air exhaust holes in the surface of the conveying pipe; and therefore, the air in the inner cabinet can be replaced and cooled, temperature balance inside the inner cabinet can be ensured, the temperature inside the inner cabinet can be prevented from becoming so high to cause damage, and the service life of equipment can be prolonged.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a power distribution cabinet with good preheating effect. Background technique [0002] The power distribution cabinets in the prior art are generally made into airtight boxes for dust prevention. The components in the electrical cabinets will generate a lot of heat during operation, which will cause the temperature in the airtight power distribution cabinet to rise, and the temperature inside the cabinet will rise. Exceeding the standard directly affects the safe and stable operation of the equipment. Moreover, the overheating problem is a continuous development process. If it is not controlled, the degree of overheating will continue to increase, and it will have a great impact on the performance of the insulation and the life of the equipment.
