The power distribution cabinet comprises apower distribution cabinet body and two cabinet doors rotationally connected to the power distribution cabinet body. A padlock is mounted on the adjacent sides of the two cabinet doors; heat dissipation windows are formed in the two sides of the power distribution cabinet; chutes are formed in the two sides of the top and the bottom in the power distribution cabinet; rotating shafts are fixedly connected to one sides, far away from the padlock, of the two cabinet doors; sliding blocks are rotationally connected to the two ends of the two rotating shafts; rotating grooves are formed in the twoends of the two sliding blocks; when the power distribution cabinet is overhauled, after the padlock on the cabinet doors is opened, the two cabinet doors are opened in a rotating mode until the cabinet doors are parallel to the two sides of the power distribution cabinet, the cabinet doors are pushed into the power distribution cabinet along the chute, and therefore the situation that the cabinetdoors are blown by external wind to affect overhauling operation of workers and even injure the arms of the workers can be completely avoided.
