[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Example

[0033] See appendix Figures 1-2 As shown, this utility model discloses a transformer protection device, including a transformer body 1 and a protective door structure. The transformer body 1 has a maintenance facade 11, and the protective door structure covers the maintenance facade 11 to open or close it. The protective door structure includes an upper door panel 2, a first side door panel 3, and a second side door panel 4 used in conjunction. The first side door panel 3 and the second side door panel 4 are arranged opposite to each other, with their ends, which are far apart, pivotally connected to the two sides of the maintenance facade 11, and their ends, which are close together, abutting against each other through a first limiting member. One end of the upper door panel 2 is pivotally connected to the upper part of the maintenance facade 11, and the other end abuts against the first side door panel 3 and the second side door panel 4 through a second limiting member.

[0034] In the protective door structure, the cooperation of the upper door panel 2, the first side door panel 3, and the second side door panel 4 not only ensures the opening and closing function of the maintenance facade 11, but also limits the positional relationship of the upper door panel 2, the first side door panel 3, and the second side door panel 4 in the closed state through the setting of the first limit member and the second limit member, ensuring the closing effect of the maintenance facade 11 and thus ensuring the protective effect. The upper door panel 2 is pivotally connected to the upper end of the maintenance facade 11, and the first side door panel 3 and the second side door panel 4 are pivotally connected to the two sides of the maintenance facade 11 respectively, so that the upper door panel 2, the first side door panel 3, and the second side door panel 4 do not interfere with each other during the opening process, and make it easier for operators to apply force from different directions to open the maintenance facade 11, improving the convenience of operation.

[0035] It should be noted that the maintenance facade 11 is usually equipped with multiple components. Operators need to conduct daily inspections and maintenance of the components on the maintenance facade 11. Therefore, the protective door structure can close the maintenance facade when not inspecting or maintaining to eliminate potential production hazards, and can also quickly open the maintenance facade when inspecting or maintaining.

[0036] To prevent operators from directly contacting components on the maintenance facade 11 after the protective door structure is opened, in some embodiments, see Appendix Figure 2 , 4 As shown, a transparent viewing window 5 is also provided on the transformer body 1. The transparent viewing window 5 is parallel to the maintenance facade 11 and close to the protective door structure. When the maintenance facade 11 is closed, the transparent viewing window 5 is located inside the protective door structure. The transparent viewing window 5 facilitates observation of the maintenance facade 11 while avoiding safety hazards caused by operators directly contacting the maintenance facade 11 (such as discharge of components on the maintenance facade 11). Furthermore, the transparent viewing window 5 is fixed to the transformer body 1 by an angle steel frame 6.

[0037] In some embodiments, see Appendix Figures 2-3 As shown, the upper door panel 2 includes an upper panel body 21 and a U-shaped side panel 22 formed around the edge of the upper panel body 21. The second limiting member is provided along the lower edge of the U-shaped side panel 22, and includes a U-shaped insertion block 23 arranged around the edge of the U-shaped side panel 22. The U-shaped insertion block 23 is connected to the U-shaped side panel 22 through a connecting plate 24. The upper ends of the first side door panel 3 and the second side door panel 4 are provided with slots 7 that are adapted to the U-shaped insertion block 23. When the maintenance facade 11 is in the closed state, the U-shaped insertion block 23 can be inserted into the slots 7 of the first side door panel 3 and the second side door panel 4.

[0038] In the upper door panel, the U-shaped side panel 22 allows the upper door panel 2 to form an abutment relationship with the first side door panel 3 and the second side door panel 4 on the vertical plane, which facilitates the limitation of the positional relationship of the upper door panel 2, the first side door panel 3, and the second side door panel 4 in the closed state by the second limiting member. The cooperation between the slot 7 and the U-shaped plug block 23 allows the first side door panel 3 and the second side door panel 4 to limit the position of the upper door panel 2, thereby preventing the upper door panel 2 from opening in the closed state.

[0039] In some embodiments, see Appendix Figure 3 , 5As shown, the first limiting member comprises a cooperation extension 31 and a side cover body, the cooperation extension 31 is arranged on the side of the first side door plate 3 facing the second side door plate 4, and the side cover body is arranged on the second side door plate 4 and can cover the cooperation extension 31 when the maintenance facade 11 is in the closed state. The cooperation between the cooperation extension 31 and the side cover body 4 can limit the positional relationship between the first side door plate 3 and the second side door plate 4 in the closed state, and the side cover body can inhibit the opening of the first side door plate 3 in the closed state due to the covering of the cooperation extension 31.

[0040] It can be understood that, when the maintenance facade 11 needs to be opened, the second side door plate 4 is first opened to remove the positional limitation of the side cover body on the cooperation extension 31, at this time, the second side door plate 4 also removes the positional limitation on the upper door plate 2; then the first side door plate 3 is opened, at this time, the first side door plate 3 removes the positional limitation on the upper door plate 2; finally, the upper door plate 2 is opened to completely open the maintenance facade 11; similarly, when the maintenance facade 11 needs to be closed, the upper door plate 2, the first side door plate 3 and the second side door plate 4 should be closed in sequence.

[0041] Further, referring to the drawings, Figure 5 As shown, the cooperation extension 31 comprises a cooperation plate, one end of the cooperation plate is integrally formed with the first side door plate 3, and the other end is bent to form a bent plate 311 away from the maintenance facade 11; the side cover body is provided with a containing groove for containing the bent plate 311. The cooperation between the bent plate 311 and the containing groove can limit the cooperation relationship between the cooperation extension 31 and the side cover body.

[0042] In some embodiments, in order to further limit the positions of the first side door plate 3 and the second side door plate 4 in the closed state, referring to the drawings, Figure 4 As shown, the angle steel frame 6 is provided with a frame insertion strip 61, and the first side door plate 3 and the second side door plate 4 are each provided with a frame insertion slot matched with the frame insertion strip 61; when the maintenance facade 11 is in the closed state, the frame insertion strip 61 is jointly inserted into the frame insertion slots of the first side door plate 3 and the second side door plate 4. Further, the frame insertion slots are located at the lower end portions of the first side door plate 3 and the second side door plate 4.

[0043] In some embodiments, the upper door plate 2, the first side door plate 3 and the second side door plate 4 are all pivotally connected to the maintenance facade 11 through hinges to ensure the smoothness of the opening and closing of the upper door plate 2, the first side door plate 3 and the second side door plate 4.

[0044] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application, and any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
