Among them, the top of the first bracket 100 in the vertical direction abuts against the bottom of the outgoing line box 300, and one side of the first bracket 100 in the first horizontal direction is connected to the box wall 400 of the transformer; the top of the second bracket 200 in the vertical direction abuts against the bottom of the first bracket 100 in the vertical direction. It can be understood that the bottom of the second bracket 200 in the vertical direction can be fixed on the base supporting the transformer or at an installation position such as the ground. Among them, the box wall 400 of the transformer can be the box wall 400 of the transformer oil tank. Among them, the a direction in the figure is the vertical direction, the b direction is the first horizontal direction, and the c direction is the second horizontal direction. The vertical direction, the first horizontal direction, and the second horizontal direction are perpendicular to each other.

[0048] In this embodiment, one side of the first bracket 100 in the first horizontal direction is connected to the box wall 400 of the transformer, and the top of the first bracket 100 in the vertical direction abuts against the bottom of the outgoing line box 300, so that the first bracket 100 forms a support for the outgoing line box 300, and the top of the second bracket 200 in the vertical direction abuts against the bottom of the first bracket 100 in the vertical direction to prevent the first bracket 100 from deforming, so that the support structure has a high structural strength, thereby ensuring the stability of the outgoing line box 300, effectively preventing the outgoing line box 300 from deforming and breaking, and the support structure occupies a small space.

[0049] Exemplarily, the included angle between the second bracket 200 and the first horizontal direction is 60° - 120°, for example 90°, to ensure that the second bracket 200 has a good support effect on the first bracket 100.

[0050] In this embodiment, continue to refer to Figures 1 to 3As shown, the first support 100 includes a first frame body 110 and a second frame body 120.

The first side of the second frame body 120 in the first horizontal direction is connected to the box wall 400 of the transformer, and the top of the second frame body 120 in the vertical direction abuts against the first frame body 110. Among them, the top of the second support 200 in the vertical direction abuts against the bottom of the first frame body 110 in the vertical direction. Exemplarily, the second frame body 120 can be first connected to the box wall 400, then the first frame body 110 is placed between the second frame body 120 and the wire outlet box 300, and finally the first frame body 110 is supported by the second support 200, which is convenient for assembly. And the top of the second support 200 in the vertical direction abuts against the bottom of the first frame body 110 in the vertical direction, which can share the force exerted by the wire outlet box 300 on the second frame body 120 through the first frame body 110, so as to reduce the acting force of the second frame body 120 on the box wall 400. And the second support 200 directly acts on the first frame body 110, which can make the support structure have good structural strength and ensure the stability of the wire outlet box 300.

[0051] In a feasible implementation manner, along the first horizontal direction, the second side of the second frame body 120 abuts against the second support 200, which can effectively improve the structural strength of the support structure.

The second frame body 120 is arranged corresponding to the first frame body 110 one by one. The bottom of the first frame body 110 in the vertical direction abuts against the top of the second support 200 in the vertical direction. Compared with the design of one first frame body 110, the design of at least two first frame bodies 110 can disperse the supporting force of the first frame body 110 on the wire outlet box 300 and effectively ensure the stability of the wire outlet box 300. And the second frame body 120 is arranged corresponding to the first frame body 110 one by one.

In addition, the bottoms of all the first frame bodies 110 in the vertical direction abut against the tops of the second support 200 in the vertical direction, that is, the second support 200 is designed as an integral structure, which effectively ensures the structural strength of the support structure.

[0053] In this embodiment, referring to Figure 1 and Figure 4As shown, the first frame body 110 may include a first upper support plate 111, a first lower support plate 112 arranged at intervals in the vertical direction, and a first reinforcing plate 113 provided between the first upper support plate 111 and the first lower support plate 112.

One side of the first upper support plate 111 facing away from the first lower support plate 112 abuts against the wire outlet box 300, and one side of the first lower support plate 112 facing away from the first upper support plate 111 abuts against the top of the second frame body 120 in the vertical direction. While ensuring the structural strength of the first frame body 110, a lightweight design of the product can be achieved.

One side surface of the first upper support plate 111 facing away from the first lower support plate 112 is attached to the bottom surface of the U-shaped plate 310 to ensure the stability of the wire outlet box 300. Among them, the first upper support plate 111 can be an arc-shaped plate.

While ensuring the structural strength of the second frame body 120, a lightweight design of the product can be achieved. Among them, the second upper support plate 121 is perpendicular to the vertical direction, and the second lower support plate 122 is arranged at an angle with the second upper support plate 121.

[0056] Exemplarily, the dimension of the first end plate 123 in the vertical direction is larger than the dimension of the second end plate 124 in the vertical direction.

[0057] Exemplarily, the second end plate 124 can abut against the second bracket 200 in the first horizontal direction to further improve the structural strength of the support structure.

[0058] Exemplarily, the second upper support plate 121 and the second lower support plate 122 are located between the first end plate 123 and the second end plate 124, so that the second frame body 120 has a relatively high structural strength.

The isosceles trapezoidal frame enables the second bracket 200 to have high structural strength and realizes the lightweight design of the product. Among them, the long bottom plate 220 can be fixed on the base for supporting the transformer or at an installation position such as the ground.

[0062] Exemplarily, the second bracket 200 is arranged at an angle with the first horizontal direction, and the range of the angle can be between 60° and 120°, such as 75°, 90° or 105°, to ensure the stable and reliable support of the second bracket 200 for the first bracket 100.

Among them, a plurality of third through holes 102 through which the third screw connection member can pass are arranged at intervals in the vertical direction on the first end plate 123, the fixing plate 600, and the base plate 510.

[0067] Exemplarily, the reinforcing member 500 includes a base plate 510 and flanges 520 disposed on both sides of the base plate 510 in the vertical direction. The two flanges 520 are welded to the box wall 400 of the transformer, that is, there is a gap formed between the base plate 510 and the box wall 400.
