Abstract

The invention relates to an anti-backflow ventilation panel for a power box, which includes a ventilation panel body, the ventilation panel body includes a frame body and a plurality of air guide plates installed in the frame body, and the two ends of the air guide plate are fixedly connected to the frame body , the air deflectors are arranged at intervals up and down; the air deflectors include an airflow introduction plate and an airflow exportation plate, the introduction plate is inclined downward relative to the frame, the outlet plate is parallel to the surface of the frame, and the upper and lower adjacent introduction plates There are lead-in grooves between them, and lead-out grooves between adjacent lead-out plates; the upper surface of the lead-in plates has an anti-backflow plate inclined toward the lead-out plates, and guide holes are evenly distributed on the lead-out plates.

Description

Technical field: [0001] The invention relates to the field of explosion-proof electrical technology, in particular to a ventilation plate used in an electric box. Background technique: [0002] At present, most of the power transmission and transformation facilities installed outdoors in the power system adopt a box-type structure, that is, a power box. The box body of the power box is generally provided with a heat insulation layer to prevent sun exposure, and an air duct is provided inside, and a ventilation plate is provided at the vent of the air duct to prevent safety problems caused by untimely heat dissipation of the power facilities. The traditional ventilation panel adopts the louver structure, and its disadvantage is that it cannot fully realize the functions of waterproof, dustproof, heat insulation, etc., resulting in problems such as water ingress, dust accumulation, and small animal invasion at the vent. Invention content: [0003] In view of the above-menti...
