Power engineering distribution box and use method thereof

The invention belongs to the technical field of electric power engineering, and particularly relates to an electric power engineering distribution box and a use method thereof.The electric power engineering distribution box comprises a box body and a working part body, and the interior of the box body is connected with the working part body through bolts; a temperature sensor is fixedly mounted in the box body, and a servo motor is fixedly mounted at the bottom of the box body; when a temperature sensor monitors that the temperature in the box body rises, a signal is transmitted to a servo motor, so that the servo motor is started, the servo motor drives a sleeve plate and a rectangular frame to move together through a lead screw, meanwhile, fan blades electrically connected in the rectangular frame start to rotate, the fan blades suck cold air outside the box body into the rectangular frame through round holes, and the cold air in the box body is cooled. And then the air is conveyed into the box body through
