An outdoor ring network cabinet

Abstract

The invention discloses an outdoor ring main unit. According to the key points of the technical scheme, the outdoor ring main unit comprises a box body; a box door is hinged to the box body; the top of the box body is provided with a box top; the box top comprises a ventilation plate connected with the top of the box body; a top plate is connected to the upper side of the ventilation plate; side plates are connected between the two ends of the ventilation plate and the top plate; an air suction hole communicating with the interior of the box body is formed in the middle of the ventilation plate, and an air suction fan is arranged on the upper side of the ventilation plate; the two ends of the ventilation plate, facing the side plates, extend out of the box body and air outlets are formed in the extension parts; a plurality of supporting bars arranged at intervals are arranged at the bottom of the box body; a bottom air inlet is formed between the adjacent supporting bars at the bottomof the box body; and side air inlets are formed in the two sides of the box body. Air flows into the box body from the bottom air inlet and the side air inlets, absorbs heat, is sucked into the interior of the box top by the air suction fan, and then is discharged from the air outlets to complete circulation flow of the air, so that the heat dissipation performance of the box body is greatly improved.

Description

technical field [0001] The invention relates to electrical equipment, in particular to an outdoor ring network cabinet. Background technique [0002] The ring network cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It has the advantages of low price, improved power supply parameters and performance, and power supply security. The ring network cabinet generally includes a cabinet body, a cabinet door, and electrical components installed inside the cabinet body. When it is used outdoors, it will be placed in the box body. thermal and aesthetic effects. [0003] The Chinese patent with the publication number CN108110642A discloses an outdoor ring network cabinet, which includes a rectangular cabinet body. The top of the cabinet body is equippe...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned ring network cabinet is convenient for heat dissipation through the setting of several ventilation holes, and through the setting of the dustproof arc cover, dust and rainwater are prevented from entering the interior of the cabinet from the ventilation holes, but the following technical defects still exist: the air enters and exits from the ventilation holes Taking away the internal heat of the cabinet, the heat dissipation effect is poor for the space above the ventilation holes. If a large number of ventilation holes are opened, the protection performance of the cabinet will be greatly reduced, which needs to be improved.
