At the same time, transformers can also be used to isolate high voltage systems to ensure the safety of people and equipment;

[0003] For example, the shell structure of a transformer disclosed in the utility model with authorization announcement number CN219267417U has changed the traditional phenomenon of fragile texture and adopted a high-strength shell for reinforcement. It will not crack or break when encountering collision with external objects, and the service life of the shell will not be guaranteed. In order to better inspect and repair the internal structure of the transformer and replace parts in the future, it is necessary to disassemble the transformer shell. However, the existing transformer shells are mostly integrated structures, so it is not convenient to disassemble them later. Auxiliary tools are needed for disassembly, which is not only time-consuming and labor-intensive, but also not practical. Utility Model Content

[0026] Specific working principle:

[0027] First, the transformer body 21 is fixedly installed on the upper surface of the base 1, and then the shells symmetrically distributed on both sides are laterally moved. When the connection between the two shells needs to be achieved, the lateral force applied to the shells on both sides is released, and then the reverse force generated by the deformation of the first spring 4 will pull the guide block 5 in the opposite direction, so that the guide block 5 slides laterally along the cross bar 3, and then the guide block 5 drives the first shell 6 installed on its top to move laterally. Similarly, the second shell 15 on the other side also moves laterally, and the two shells move toward each other. Then, when the first shell 6 moves laterally, it will drive the extension rod 7 to move synchronously and input it into the adapter groove 17 opened on the top side wall of the second shell 15. When the extension rod 7 is completely input into the inner side of the adapter groove 17, the reverse force generated by the deformation of the second spring 8 will push The locking block 9 is then input into the inner side of the locking hole 18 at one end of the locking block 9, so as to realize the preliminary connection between the two shells. At the same time, when the locking block 9 moves, the auxiliary slide plate 10 will be driven to move accordingly, so as to improve the stability of the locking block 9 during the movement and prevent it from being offset in position. When the second shell 15 moves laterally, the card strip 19 will be driven to slide along the card slot 11. When the card strip 19 moves to a certain position, the protrusion 20 will be input into the inner side of the groove 12, so as to further realize the snap connection between the two shells. At the same time, when the two shells are connected, the sealing gasket 14 will be input into the inner side of the sealing groove 16, so as to improve the sealing of the connection between the two. Since a plurality of heat dissipation fins 22 are evenly distributed on both sides of the transformer body 21, the plurality of heat dissipation fins 22 provided in combination can achieve the purpose of efficient heat dissipation.
