[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] <Example 1>

[0026] like Figure 1-Figure 2 As shown, the transformer box provided in the embodiment of the present application includes a box body 100, two frame bars 200, two first door panels 300, a second door panel 400 and a positioning cylinder 800, wherein the box body 100 is a container for storing and installing the transformer, and the box body 100 is surrounded by multiple side panels 110 and a top panel and a bottom panel, and one of the side panels 110 of the box body 100 has an opening 700, through which the relevant components of the transformer can be installed into the box body 100.

[0027] In this embodiment, the frame strip 200 is a long strip structure, and the frame strip 200 can be understood as a structure similar to a door frame. Two frame strips 200 are arranged on both sides of the width direction of the opening 700, and the length of each frame strip 200 is greater than the length of the opening 700. The first door panels 300 are arranged one-to-one with the frame strips 200, and the two first door panels 300 are respectively hingedly connected to the corresponding frame strips 200, so that the two first door panels 300 can close the side panels 110 of the box body 100 in a flat opening manner.

[0028] The area of ​​the second door panel 400 is larger than the area of ​​the opening 700 of the box body 100, and the second door panel 400 is hingedly connected to the bottom end of the opening 700 of the box body 100. Specifically, a hinge 900 is provided on the box body 100, and the hinge 900 is provided below the opening 700. The second door panel 400 is also located outside the two first door panels 300, and the second door panel 400 can perform a secondary seal on the opening 700.

[0029] like Figure 2As shown, a vertical slide groove 600 is provided on the surface of the vertical side wall of the second door panel 400, and a T-shaped column 500 is elastically connected in the vertical slide groove 600. Specifically, a coil spring is provided in the vertical slide groove 600, one end of the coil spring is fixedly connected to the wall surface of the vertical slide groove 600, and the other end of the coil spring is slidably connected to the horizontal section of the sliding T-shaped column 500, so that the T-shaped column 500 can move up and down along the position of the vertical slide groove 600.

[0030] Preferably, the upper and lower ends of the outer surface of the first door panel 300 may be provided with convex strips 210, and correspondingly, the inner surface of the second door panel 400 may be provided with a slot 430 used in conjunction with the convex strips 210. When the second door panel 400 is attached to the first door panel 300, the convex strips 210 of the first door panel 300 are located in the slot 430 of the second door panel 400, thereby reinforcing the connection stability between the two.

[0031] In this embodiment, the positioning cylinder 800 is a cylinder disposed on the box body 100, and the positioning cylinder 800 is disposed beside the opening 700, and the axis of the positioning cylinder 800 is perpendicular to the surface where the opening 700 is located. When the second door panel 400 is placed vertically on the ground and is in a fitted state with the first door panel 300, the T-shaped column 500 is located below the positioning cylinder 800. Therefore, in actual use, the T-shaped column 500 can be slid upward in advance and the spiral spring can be squeezed so that the bottom surface of the vertical section of the T-shaped column 500 can abut against the positioning cylinder 800, thereby achieving the function of fixing the second door panel 400.

[0032] In the transformer box and dry-type transformer provided in the embodiment of the present application, two frame bars 200 are symmetrically arranged at the opening 700 of the side plate 110 of the box body 100, and each frame bar 200 is hingedly connected to a first door panel 300, and the first door panel 300 can perform a first seal on the opening 700. The second door panel 400 is hingedly connected to the bottom end of the box body 100, and the second door panel 400 is located on the outside of the first door panel 300. The vertical side surface of the second door panel 400 is fixed to the positioning cylinder 800 through a T-shaped column 500, thereby achieving a second seal on the opening 700. The above structural design can simplify the traditional installation method. At the same time, the use of a multi-sealing method can also improve the sealing of the box body 100 to prevent rainwater from entering the box body 100, thereby affecting the performance of the transformer.

[0033] In some implementations, a groove 410 is provided on the inner surface of the second door panel 400, and a plurality of rollers 420 are provided in the groove 410, and the rollers 420 can rotate at a fixed point in the groove 410. When it is necessary to transport the relevant components of the transformer to the inside of the box 100, the second door panel 400 can be rotated to a position overlapping the ground, and then the relevant components are placed on the rollers 420, so that the components are transported to the box 100 by rolling, thereby simplifying the traditional transportation process.
