description The utility model discloses an air type ring main unit. The air type ring main unit comprises a cabinet body. The whole cabinet body is closed. An air inlet pipe is arranged at the lower part of one side of the cabinet body; an air outlet pipe is arranged at the top of the cabinet body; a lower partition plate and an upper partition plate are arranged in the cabinet body; the lower partition plateis arranged above the air inlet pipe and provided with ventilation holes. An upward protruding part is arranged in the middle of the upper partition plate, and a ventilation opening is formed in theside face of the protruding part. By means of the technical scheme, dry air can be blown into the box bodies through the external air supply device, ventilation and heat dissipation are achieved, themultiple looped network box bodies can be connected in parallel or in series, and relatively-closed air circulation is achieved. Dust and moisture in the air are effectively removed, the ring main unit is enabled to be in a goo
