Power distribution box

Abstract

The invention discloses a power distribution box comprising a box body. The bottom part of the box body is provided with a ventilator which is internally provided with a refrigerator. The lower end ofthe ventilator is also provided with a dust collection tank. The lower end of the dust collection tank is provided with a slide rail. The two ends of the dust collection tank are provided with dust inlet holes. The ventilator comprises an air inlet and an air outlet. The air inlet is installed on the right side surface of the bottom part of the box body. The air outlet is installed on the left side surface of the top part of the box body. A vertical filter screen A is installed behind the air inlet. A vertical filter screen B is installed behind the air outlet. The lower end of the filter screen B is provided with a downwardly tilted baffle plate. The lower ends of the filter screen A and the filter screen B are provided with dust outlet holes which are communicated with the dust inlet holes. The advantages of the power distribution box are that the ventilation duct is installed on the bottom part of the box body so that the flow velocity of the air can be accelerated and cooling canbe facilitated; the refrigerator is installed on the bottom part so that the heat radiation function can be realized, the refrigerant can be recycled and thus the use amount of the refrigerant can besaved; and the filter screens and the dust collection tank are connected so that the dust in the filter screens can be processed in time.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a distribution box. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. Because the distribution box is closed outdoors, its waterproof performance is good, but its heat dissipation performance is poor. After a long period of use, the distribution box is prone to overheating, which will damage the parts in the box, cause a short circuit accident, and reduce the practical performance. , affect the normal work of the original and increase the maintenance cost. Contents of the invention [0003] The object of the present invention is to provide a power distribution box with good heat dissipation effect and anti-theft for the deficiencies of the pri...

AI Technical Summary

Problems solved by technology

Since the distribution box is closed outdoors, its waterproof performance is good, but its heat dissipation performance is poor. After a long-term use of the distribution box, it is easy to overheat and damage the parts in the box, resulting in a short circuit accident and reducing the practical performance. , affect the normal work of the original, increase maintenance costs
