The counterclockwise rotating force applying rod 213 will drive the insertion rod 212 to rotate inside the threaded hole, and the insertion rod 212 rotating inside the threaded hole will gradually disengage from the insertion hole. When the insertion rod 212 is completely out of the insertion hole, the force applying rod 213 drives the circular sleeve 210, the rotating shaft 206 and the extrusion plate 207 to rotate counterclockwise. The extrusion plate 207 will rotate and drive the force-bearing plate 208, the movable ring 203, the shielding bar 1 204 and the shielding bar 205 to move. At this time, the opening size of the ventilation hole can be understood by the position of the circular block 3 in the ventilation hole. After the size adjustment is completed, rotate the force applying rod 213 clockwise until the insertion rod 212 re-enters the insertion hole. When the installation environment of the transformer JP cabinet is cold, just repeat the above steps in reverse. In an environment with a large temperature difference, the heat dissipation efficiency of the transformer JP cabinet is guaranteed, and the use effect of the transformer JP cabinet is improved.
