Abstract

The invention discloses a power distribution box, which comprises a box body. A ventilator is installed at the bottom of the box body. A refrigerator is installed inside the ventilator. There are ash inlet holes at both ends of the ash trough. The ventilator includes an air inlet and an air outlet. Net A, a vertical filter B is installed behind the air outlet, and a slanted downward baffle is installed at the lower end of the filter B. Both the filter A and the lower ends of the filter B have ash outlet holes, the ash outlet holes and the ash inlet holes connected. Its advantages are: the present invention increases the flow velocity of the air by installing a ventilation pipe at the bottom of the box body, which is convenient for cooling; the refrigerator is installed at the bottom, which can play a heat dissipation function, and at the same time, the refrigerant can be recycled, saving the cost of the refrigerant. Dosage; by connecting the filter screen with the dust tank, the dust inside the filter screen can be disposed of 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...
