Because the ventilation plate 5, the wide plate 1, and the long plate 2 all have ventilation holes, the fan 7 blows the heat out of the transformer The heat dissipation inside the transformer casing can be completed. When installing the transformer casing, align the hollow rod 34 of the long plate 2 or the wide plate 1 with the slot 33 of the wide plate 1 or the long plate 2, and completely install the hollow rod 34 into the slot 33. Then insert the fixing rod 32 into the hole of the slot 33 and the hollow rod 34. Repeat four times at the four joints to complete the installation of the four corners. Then, align the threaded holes of the fixing frame 35 with the threaded holes of the wide plate 1 and the long plate 2, fix them with bolts 36, and then put the support frame 4 into the bottom to complete the installation. When inspecting, move the blocking rod 98 to the door lock casing 9 5, the door handle 94 can be pulled to open the door. After the inspection is completed, the door latch 93 is pushed back to the stopper 97. When the door latch 93 moves to the right, the stopper 97 and the stopper 98 will be pushed to the left. Because the left side of the stopper 97 and the stopper 98 is not blocked, the door latch 93 can be moved inside. When the door latch 93 moves to the right, the stopper 98 will be restricted by the door lock housing 95, so the door latch 93 cannot move. The door panel 91 can be locked, and the lock hole 99 can be used to place a padlock to lock the door panel 91, so that irrelevant personnel and animals cannot enter the transformer housing.
