[0044] The staff then pulls up the pressure plate 35, which drives the stop rod 37 to move upward and causes the moving rod 39 to slide in the sleeve 38, thereby releasing the stop rod 37 from the stopper at one end of the fastening rod 33. Then, pulling the fastening rod 33 will stretch the spring 34 and cause the fastening rod 33 to disengage from the lock 31, disconnecting the fastening rod 33 from the pressing rod 30, and then lifting the pressing rod 30 to disconnect the connection between the base 29 and the pressing rod 30, thereby facilitating the staff to remove the voltage transformer protective shell 9, thereby facilitating the voltage transformer itself inside the voltage transformer protective shell 9. The body is replaced, and then the voltage transformer protection shell 9 is placed on the support plate 7, and the pressing rod 30 is installed on the base 29. At the same time, the fastening rod 33 is loosened. Under the reverse force of the spring 34, one end of the fastening rod 33 will extend into the lock 31, thereby realizing the fastening of the fastening rod 33 to the pressing rod 30. At the same time, the pressing plate 35 is loosened, and the moving rod 39 is moved downward in the sleeve 38. At the same time, the stop rod 37 is moved downward and stopped on one side of the fastening rod 33. At the same time, the pressing plate 35 presses the top of the pressing rod 30, thereby facilitating the installation of the voltage transformer.

[0045] Then, starting the motor 22 to reverse will cause the support plate 7 to drive the voltage transformer protective shell 9 and the voltage transformer protective cover 10 to move into the cabinet 1, and at the same time, the plug-in rod 16 will move down and insert the plug-in rod 16 into the inside of the plug-in slot 19, thereby improving the stability of the voltage transformer protective shell 9 and the voltage transformer protective cover 10 during movement, and improving the transmission smoothness of the voltage transformer protective shell 9 and the voltage transformer protective cover 10; at the same time, the cabinet door 2 is flipped over and the cabinet 1 is closed. This design avoids the staff from replacing the voltage transformer body inside the cabinet 1, thereby improving the efficiency of disassembly and assembly of the voltage transformer body.
