[0032] In this embodiment, the first bracket 31 and the second bracket 32 are both semicircular concentric ring structures, and are rotatably connected therebetween (see Figure 2 and Figure 3), forming a bracket structure that can be folded along the middle position; the bracket assembly 3 is folded before being placed in the isolation transformer box, and then unfolded after being placed in the isolation transformer box, which facilitates the installation and arrangement of the bracket assembly 3.
[0033] Furthermore, a plurality of first positioning members 33 corresponding to the support assembly 2 are disposed at the lower end of the first bracket 31 ; and a second positioning member 34 corresponding to the support assembly 2 is disposed at the lower end of the second bracket 32 .
[0034] In this embodiment, three first positioning members 33 are provided at the lower end of the first bracket 31, and a second positioning member 34 is provided at the lower end of the second bracket 32 (see Figure 2 and Figure 3 ), thereby forming a positioning plane with four positioning points, and the upper end of the support component 2 is provided with a connecting structure corresponding to the above four positioning points, so that after the bracket component 3 is placed on the support component 2, the two can be connected and positioned.
[0035] Furthermore, the first positioning member 33 and the second positioning member 34 are both hollow steel pipes.
[0036] In this embodiment, the first positioning member 33 and the second positioning member 34 are both made of a hollow steel pipe with an inner diameter of 5 mm and a wall thickness of 0.5 mm. The first positioning member 33 and the second positioning member 34 are sleeved on the upper end of the support component 2, and the position of the support component 2 is fixed by the hollow structure of the steel pipe.
[0037] Furthermore, the support assembly 2 includes a plurality of support rods; the plurality of support rods are vertically arranged at the upper end of the base frame 1; the first positioning member 33 and the second positioning member 34 are detachably arranged at the upper end of the support rods.
[0038] In this embodiment, the support assembly 2 includes four support rods, and the positions of the four support rods at the upper end of the base frame 1 correspond to the positions of the first positioning member 33 and the second positioning member 34 (located on the same projection plane in the vertical direction), so that after the bracket assembly 3 is placed on the support assembly 2, the four support rods can be inserted into the hollow structures of the first positioning member 33 and the second positioning member 34 respectively.
[0039] Furthermore, the support rod is a stainless steel pipe.
[0040] In this embodiment, the support rod is made of a stainless steel pipe with an outer diameter of 4 mm, and the top of the stainless steel pipe is inserted into the hollow structure of the first positioning member 33 and the second positioning member 34 to achieve a fixing effect between the support assembly 2 and the bracket assembly 3; the cable of the isolation transformer can be coiled on the stainless steel pipe and fixed with a cable tie to achieve the storage and sorting effect of the isolation transformer cable;
[0041] In addition, the support rod can be designed with different heights according to the different specifications of the isolation transformer box. For example, when the height of the support rod is 200mm, the transformer may be soaked in water only when the water inflow into the isolation transformer box exceeds 200mm.
[0042] Embodiment 2
[0043] like Figures 4 to 6 As shown, this embodiment provides an isolation transformer box, including: a box body 4 and a box cover 5, and also includes a bracket structure; the box cover 5 is installed on the box body 4; the base frame 1 is arranged in the box body 4.
[0044] In this embodiment, when the bracket structure is placed in the box body 4, the base frame 1 is first placed at the bottom of the box body 4, and then the bracket assembly 3 in the folded state is placed on the upper end of the support assembly 2 and unfolded. Under the overhead effect of the support assembly 2, the bracket assembly 3 is located at a certain height position in the box body 4, and the isolation transformer is placed in the box body 4 so that it is located at the upper end of the bracket assembly 3. Therefore, the isolation transformer is suspended in the box body 4 through the bracket structure to prevent the isolation transformer from sinking to the bottom and being soaked in water; the surface of the box body 4 is anodized, and the box cover 5 is installed on the box body 4 to protect the isolation transformer in the box body 4.

[0046] In this embodiment, two primary wire holes 61 are provided on the box body 4, and a silicone plug 62 and a wire lock 63 are provided in each primary wire hole 61. The cable of the isolation transformer extends from the primary wire hole 61 to the outside of the box body 4. The silicone plug 62 and the wire lock 63 can seal the gap between the cable and the primary wire hole 61 to prevent moisture from entering the box body 4.
[0047] Furthermore, a ground wire connector 71 and at least one secondary wire hole 72 are also provided on the box body 4 .
[0048] In this embodiment, the ground wire connector 71 is welded on the side wall of the box body 4. The ground wire connector 71 has a wiring hole.
