The invention relates to the technical field of leakage check of transformer oil tanks, and specifically relates to an air pressure leakage check method for a transformer oil tank. The method comprises the following steps of: (1) utilizing a flange hole or a screw hole formed in a tank cover to connect an air pressure meter and a breather pipe joint; (2) sealing the whole transformer oil tank, opening an inflation valve and filling oil-free and water-free compressed air in the oil tank till the air pressure reaches 10-15kPa; (3) brushing a leaking stoppage solution on sealing bonding wires from top to bottom when the pressure reached in the step (2) is changed in 8-10min, and making a to-be welded marker with chalk at each checked place where bubbles come out; and (4) if a sealing test shows that no place has leakage, proving that the transformer oil tank is qualified; otherwise, welding and repairing the transformer oil tank after pressure is released. According to the method provided by the invention, the oil tank is filled with compressed air for checking whether the oil tank has a leakage phenomenon.
