Anti-condensation apparatus for switch cabinet in limestone powder station section

The invention discloses an anti-condensation apparatus for a switch cabinet in a limestone powder station section, and belongs to the anti-condensation technical field of switch cabinets. The anti-condensation apparatus for the switch cabinet in the limestone powder station section comprises a blocking apparatus and a ventilating apparatus, wherein the blocking apparatus is connected with the ventilating apparatus; the blocking apparatus comprises a bottom layer and a fireproof insulating layer; the bottom layer and the fireproof insulating layer form a U-shaped cable trench; and the ventilating apparatus comprises a rainproof cover and a silk screen object. According to the anti-condensation apparatus for the switch cabinet in the limestone powder station section, even if a small amount of vapor enters the cable trench, the water vapor can be discharged completely before the water vapor enters a power distribution room; and meanwhile, the interior of the cable trench can be kept dry at any time to ensure the
