[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0041] Please refer to Figure 1-Figure 7 The double-door structure 100, the transformer box 1000 and the box-type transformer substation provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.
[0042] refer to Figure 1 , Figure 2 as well as Figure 6 The double-door structure 100 is applied to a transformer box 1000 in a box-type transformer substation. The double-door structure 100 includes a door frame 110, a first door panel 120, a second door panel 130 and a protective panel 140; wherein the first door panel 120 includes a first door body 121 and a first bending panel 122 connected to each other, and the second door panel 130 includes a second door body 131 and a second bending panel 132 connected to each other;
[0043] The first door body 121 and the second door body 131 are both connected to the door frame 110. The inner side of the bend of the first bent plate 122 forms a limited cavity 125. The second bent plate 132 is used to be accommodated in the limited cavity 125 when the door is closed. The protective plate 140 is connected to the first bent plate 122 and simultaneously abuts against the door frame 110 and the second bent plate 132.
[0044] During operation, the first door body 121 is used to drive the first bending plate 122 and the protective plate 140 to rotate relative to the door frame 110, and the second door body 131 is used to drive the second bending plate 132 to rotate relative to the door frame 110. By accommodating the second bending plate 132 in the closed state in the limiting cavity 125 formed on the inner side of the bend of the first bending plate 122, dust and impurities can be prevented from passing through the gap between the two door panels; the protective plate 140 connected to the first bending plate 122 simultaneously supports the second bending plate 132 and the door frame 110, thereby protecting the gap between the two door panels and the door frame 110 and preventing excessive dust and impurities from passing through and causing dust accumulation in the inner cavity of the transformer box 1000.
[0045] It is worth noting that the first bending plate 122 and the second bending plate 132 respectively have at least two angled parts, thereby forming a bending structure. The limiting cavity 125 formed on the inner side of the bend refers to a semi-enclosed inner cavity enclosed by the angled part of the first bending plate 122.
[0046] In this embodiment, the sides of the first door body 121 and the second door body 131 that are away from each other are connected to the door frame 110 through hinges or hinges, so that the first door body 121 and the second door body 131 can rotate relative to the door frame 110, thereby making the double-door structure 100 open or closed. Specifically, when the box-type substation is performing normal substation operations, the double-door structure 100 is in a closed state; when the box-type substation is undergoing maintenance and servicing operations, the double-door structure 100 is in an open state.
[0047] It is worth noting that when the door is closed, the first door body 121 and the second door body 131 are side by side, and the second bending plate 132 will be accommodated in the limiting cavity 125; when the door is opened, the first door body 121 and the second door body 131 will move away from each other, and the second bending plate 132 will also be separated from the limiting cavity 125 and at the same time be separated from the first bending plate 122 and the protective plate 140.
[0048] refer to Figure 2 and Figure 3 In order to improve the anti-theft performance of the transformer box 1000, at least one of the first door 121 and the second door 131 is provided with a lock opening 150.
[0049] In this embodiment, the locking opening 150 is only opened on the second door body 131; of course, in other embodiments of the present invention, the locking opening 150 may also be only opened on the first door body 121, or the first door body 121 and the second door body 131 may both be provided with a locking opening 150, and multiple locks may be installed at the same time to improve safety.
[0050] refer to Figure 4The protective plate 140 includes a first section 141, a second section 142 and a third section 143. The first section 141, the second section 142 and the third section 143 are all connected to the first bending plate 122. The two ends of the second section 142 are respectively connected to the first section 141 and the third section 143. The first section 141 and the third section 143 are both located on the same side of the second section 142. In addition, the end of the first section 141 away from the second section 142 is higher than the end of the first section 141 close to the second section 142.
[0051] In the above technical solution, by limiting the structure of the protection plate 140, the protection plate 140 can better play a protective role between the first bent plate 122, the second bent plate 132 and the door frame 110. The first section 141 is tilted to guide the small particles of impurities gathered on the upper side of the first section 141 so that they can fall off the protection plate 140 under the action of gravity.
[0052] refer to Figure 6 and Figure 7 A first recess 1225 is formed at the end of the first bending plate 122, a second recess 1325 is formed at the end of the second bending plate 132, the protective plate 140 is connected to the first recess 1225 and abuts against the second recess. By respectively providing the first recess 1225 and the second recess 1325 on the first bending plate 122 and the second bending plate 132, the first bending plate 122 is connected to the protective plate 140, while the protective plate 140 can abut against the second bending plate 132, thereby ensuring the protection level.

Specifically, the first notch 1225 is opened at the end of the first sub-plate 1221, and the first notch 1225 is spaced from the second sub-plate 1222 and the third sub-plate 1223.
[0054] In this embodiment, the first bending plate 122 is made into a U-shaped structure, so as to form a limited inner cavity to accommodate the second bending plate 132. The gap between the two door panels is blocked by the cooperation with the second bending plate 132 to prevent excessive dust and impurities from entering.
[0055] refer to Figure 7The second bending plate 132 includes a fourth sub-plate 1321 and a fifth sub-plate 1322 which are vertically connected. The fourth sub-plate 1321 is connected to the second door body 131. The fourth sub-plate 1321 and the fifth sub-plate 1322 are both used to be accommodated in the limiting cavity 125 in the door closing state, and the protective plate 140 is supported by the fourth sub-plate 1321. Specifically, the second groove is opened at the end of the fourth sub-segment, and the second notch 1325 is spaced from the fifth sub-segment.
[0056] In this embodiment, the second bending plate 132 is made into an L-shaped structure, so that it can be accommodated in the limiting cavity when the door is closed and cooperate with the first bending plate 122, so that dust and impurities that tend to pass through the gap between the two door panels can be blocked on the outside, so as to avoid dust accumulation in the inner cavity of the transformer box 1000.
[0057] refer to Figure 4 Figure 6 and Figure 7 In order to improve the convenience of opening and closing the door panel, the first door panel 120 also includes a first inclined plate 123, which is connected to the upper side of the first door body 121, and the end of the first inclined plate 123 away from the first door body 121 is lower than the end of the first inclined plate 123 close to the first door body 121; and the second door panel 130 also includes a second inclined plate 133, which is connected to the upper side of the second door body 131, and the end of the second inclined plate 133 away from the second door body 131 is lower than the end of the second inclined plate 133 close to the second door body 131.
[0058] In this embodiment, the angle between the first inclined plate 123 and the plane where the end face of the first door body 121 is located is 45°, and the angle between the second inclined plate 133 and the plane where the end face of the second door body 131 is located is 45°; of course, in other embodiments of the present invention, the sizes of the above two angles can also be 15°, 30°, 60°, 75°, etc., and the specific angle sizes are not limited.
