[0080] The box-type transformer is placed outdoors, and the box body 100 is easy to be collided from outside or eroded by hail and other extreme weather, which may cause the box body 100 of the box-type transformer to be deformed, and the deformed box body 100 cannot effectively protect the transformer body in the box body 100.

[0081] In view of the above technical problems, in the utility model, please see Figure 5 and Figure 6The protection device of the box-type transformer further comprises a roof 400 and a first damping mechanism 500.

Thus, the deformation of the box body 100 caused by the external force acting on the box body 100 can be prevented, so that the box body 100 is protected, and the transformer body in the box body 100 is effectively protected.

[0083] In some embodiments, referring to Figure 5 and Figure 6 the hole wall of the guide hole 511 is provided with a first limiting portion 512, and the other one of the sliding piece 510 and the guide 520 is provided with a second limiting portion 521 limited between the first limiting portion 512 and the hole bottom of the guide hole 511.

[0084] In the embodiment, the second limiting portion 521 is limited between the first limiting portion 512 and the hole bottom of the guide hole 511, so that the second limiting portion 521 is always in the guide hole 511, and the sliding piece 510 and the guide 520 can be prevented from being separated.

[0085] In other embodiments, referring to Figure 5The roof 400 comprises a connecting piece 410 and a protection plate 420 connected to the opposite sides of the connecting piece 410 in a slanting manner, and the first damping mechanism 500 connects the connecting piece 410 and the box body 100; the protection device of the box-type transformer further comprises a second damping mechanism 600, and the second damping mechanism 600 connects the protection plate 420 and the box body 100.

[0086] In the embodiment, the protection plate 420 is inclined from top to bottom, so that rain or snow falling on the protection plate 420 can be guided out of the protection plate 420, so as to prevent the rain or snow from accumulating on the protection plate 420.

[0087] By arranging the second damping mechanism 600, the second damping mechanism 600 connects the protection plate 420 and the box body 100, so that the connecting points between the roof 400 and the box body 100 are increased, and the connection between the roof 400 and the box body 100 is enhanced; and the second damping mechanism 600 has a damping function, so that the deformation of the box body 100 caused by external force can be prevented, so as to protect the box body 100, and further effectively protect the transformer body in the box body 100.

[0088] It should be noted that the second damping mechanism 600 can have the same structure as the first damping mechanism 500, and details are not repeated here.
