[0032] The protective member 4 includes a protective shell 41 installed on the surface of the transformer body 2, a folding door 42 is installed inside the protective shell 41, and two groups of folding doors 42 are provided. The two groups of folding doors 42 are connected by magnets. Connecting rods 43 are fixedly connected to both sides of the protective shell 41, and bolts 44 are movably sleeved inside the connecting rods 43. The bolts 44 are threadedly connected to the bottom plate 1. The protective shell 41 is connected to the bottom plate 1 through the bolts 44. A moving part 45 is installed on one side of the protective shell 41 and away from the folding door 42. A guide member 5 is provided on the top of the protective shell 41. The transformer body 2 is located on the surface of the bottom plate 1, and the mounting plate 3 extends to the bottom of the bottom plate 1. The protective shell 41 can make the transformer body 2 waterproof, dustproof, anti-collision, and anti-animal. The setting of the bolts 44 can fix the protective shell 41 on the surface of the transformer body 2. A circular array of heat dissipation holes is opened on both sides of the protective shell 41 to facilitate the heat dissipation of the transformer body 2.

[0033] The movable part 45 includes a limit block 451 fixed on the surface of the base plate 1, and a pull rod 452 is movably sleeved inside the limit block 451. One end of the pull rod 452 and the end away from the limit block 451 is fixedly connected to the protective shell 41. A ring-shaped array of magnetic blocks 453 are installed on the surface of the pull rod 452 and the end close to the protective shell 41. An iron block 454 is installed on the inner side of the limit block 451. The magnetic block 453 and the iron block 454 are symmetrical to each other and are magnetically connected. The connection between the two can position the protective shell 41 when the protective shell 41 is separated from the transformer body 2.

[0034] The moving part 45 also includes a sleeve 455 fixed on the surface of the base plate 1. The sleeve 455 is provided with two groups and is respectively located on both sides of the protective shell 41. A sliding rod 456 is fixedly sleeved inside the sleeve 455. A spring 457 is sleeved on the surface of the sliding rod 456. One end of the spring 457 is fixedly connected to the sleeve 455. The spring 457 and the sleeve 455 are provided in two symmetrical groups to make the protective shell 41 more stable when moving.

[0035] A slider 458 is movably sleeved on the surface of the slide rod 456, one end of the slider 458 is fixedly connected to the other end of the spring 457, and a connecting plate 459 is fixedly connected to the surface of the slider 458.
