[0037] Oil-immersed transformers usually require a pad structure to be set at the bottom of the transformer core to support the core and facilitate the lifting and installation of the core. The pad structure includes but is not limited to a pad for supporting the core, a pad for installing the pad, and an insulating plate for isolating the core and the pad. The existing pad structure will install the pad through a bolt structure, a slot-type clamping structure, etc. When using the above method, holes or slots will be opened on the pad before installation. Not only does it have many installation steps, but it is also difficult to install and the efficiency is low during the actual installation process.

[0038] For the above questions, please refer to Figures 1 to 3As shown, an embodiment of the present specification proposes a foot structure 100 for supporting the iron core 4 of a transformer. The foot structure 100 includes a base 1, an insulating member 2 and a support member 3. The base 1 is provided with a frame structure 12. The frame structure 12 is provided with an installation space 123. The installation space 123 is configured to install the iron core 4 of the transformer. The insulating member 2 is provided in the installation space 123. The insulating member 2 is configured to be located between the base 1 and the iron core 4. The support member 3 is provided in the installation space 123 to be configured to support the iron core 4.

[0039] In this embodiment, the pad structure 100 is used to support the iron core 4 of the transformer. The pad structure 100 is connected, abutted, or limitedly installed to install the iron core 4 of the transformer. The pad structure 100 includes a base 1, an insulating member 2, and a support member 3. The base 1 is the main supporting component of the pad structure 100. The base 1 can be a substrate, a base, a base frame, etc. Preferably, the base 1 is a plate structure to reduce the space occupied by the pad structure 100 and is suitable for a flat area.

[0040] At the same time, the base 1 is also used to install and place the insulating part 2 and the support part 3. The insulating part 2 is used to isolate the iron core 4 and the base 1 of the transformer. The insulating part 2 can be an insulating board, an insulating pad, an insulating blanket or other structures. The material of the insulating part 2 can be a composite laminated cardboard, an epoxy resin board, a glass fiber board or a rubber board, etc., which is not limited here. The support part 3 is arranged on the base 1, which is used to support the base 1. The support part 3 can be a support plate or a support block. Preferably, the support part 3 is a support block with multiple steps, and the multiple steps formed on its surface are used to abut the multiple sharp corners of the iron core 4 to achieve stable support for the iron core 4.

[0041] In this embodiment, the base 1 is provided with a frame structure 12, and the frame structure 12 is a structure formed by connecting one or more of a plate structure, a column structure, a strip structure, a rib structure, a sheet structure, and a rod structure. For example, a plurality of plate structures are connected to each other, or a plurality of column structures are connected to each other, or a plurality of rod structures are connected to each other to form the frame structure 12, or a plate structure and a rod structure are connected to each other to form the frame structure 12, or a rod structure and a strip structure are connected to each other to form the frame structure 12, which is not limited here.

[0042] It can be understood that by using the above-mentioned basic structures such as plate structure, column structure, strip structure, rib structure, sheet structure, and rod structure, a closed or semi-closed frame structure 12 can be formed, and an installation space 123 can be formed inside the frame structure 12. The installation space 123 can be the entire internal area enclosed by the frame structure 12, or it can be a partial area enclosed by the frame structure 12.

[0043] It can be understood that the installation space 123 provided in the frame structure 12 is used to install and place the iron core 4 of the transformer, and is also used to install and place the insulating member 2 and the support member 3, and the transformer core 4 is supported by the support member 3. Specifically, the insulating member 2 is limited in the installation space 123, and the insulating member 2 abuts against the surface of the base 1 for installing the frame structure 12, so as to achieve insulation isolation between the transformer core 4 and the base 1 and the installation area. At the same time, the support is also limited in the installation space 123, and the support member 3 is provided on the side of the insulating member 2 facing away from the base 1, and the side of the support member 3 facing away from the insulating member 2 is used to support and abut the iron core 4 of the transformer.

[0044] It can be understood that by setting up a frame structure 12 and setting up an installation space 123 in the frame structure 12, the insulating member 2 and the support member 3 can be directly limited and set in the installation space 123, and the positions of the insulating member 2 and the support member 3 are limited and fixed by the frame structure 12 to keep the position of the insulating member 2 relative to the base 1 and the support member 3 relative to the base 1 fixed. At the same time, when the transformer core 4 is set in the installation space 123, the insulating member 2 and the support member 3 located between the two can also be limited and fixed by the transformer core 4 and the base 1 to keep the transformer core 4 and the pad structure 100 as a whole stable.

[0045] Compared with traditional screw connection and slot connection methods, the present application does not require the opening of screw holes or slots on the insulating part 2 and the support part 3, thereby reducing the manufacturing difficulty and reducing the manufacturing size of the insulating part 2 and the support to reduce the possible interference of the support part 3 with the multi-level sharp corners of the transformer core 4, while also reducing the difficulty during installation and effectively improving the efficiency of the production and installation of the pad structure 100.

[0046] The pad structure 100 provided in this specification is used to support the iron core 4 of the transformer. The pad structure 100 includes a base 1, an insulating member 2 and a support member 3. The base 1 is a structural support component of the pad structure 100, which is used to install the insulating member 2 and the support member 3. The base 1 is provided with a frame structure 12, and the frame structure 12 is provided with an installation space 123. The installation space 123 is configured to install the iron core 4 of the transformer. The insulating member 2 is provided on the base 1 and limited in the installation space 123. The insulating member 2 is configured to be located between the base 1 and the iron core 4, and the support member 3 is provided in the installation space 123. The support member 3 is configured to support the iron core 4. By providing the frame structure 12, the insulating member 2 and the support member 3 can be directly placed in the installation space 123 formed by the frame structure 12, and the insulating member 2 and the support are limited by the frame structure 12, so as to simplify the structure of the pad structure 100, and simplify the installation process of the insulating member 2 and the support member 3, reduce the installation difficulty of the pad structure 100, and improve production and installation efficiency.

[0047] See Figure 1 and Figure 4 In one embodiment of the present specification, the support member 3 includes a support surface 31 and a side surface 32 connected to the support surface 31 . The support surface 31 is configured to support the iron core 4 , and at least part of the frame structure 12 abuts against the side surface 32 .

[0048] In this embodiment, the support surface 31 provided on the support member 3 is a surface away from the side of the insulating member 2, and the support surface 31 can be a plane, a curved surface or a plurality of stepped planes. The support surface 31 abuts against the iron core 4 of the transformer to support the iron core 4 of the transformer. At the same time, the support member 3 also includes a side surface 32 connected to the support surface 31. On the basis that the support surface 31 is a plane, the plane where the side surface 32 is located is perpendicular to the plane where the support surface 31 is located, that is, the area where the side surface 32 is located is a plurality of vertical surfaces surrounding the support surface 31, which can be a front side surface 32, a rear side surface 32, a left side surface 32 or a right side surface 32, etc., wherein at least part of the area of ​​the side surface 32 abuts against the frame structure 12.

[0049] It can be understood that at least part of the frame structure 12 abuts against the side 32 of the support member 3, that is, the side 32 of the support member 3 is always in abutment with the frame structure 12, thereby ensuring that the support member 3 can be applicable to frame structures 12 of different structural forms, and the support member 3 is always limited in the installation space 123, so that the support member 3 can be directly installed in the installation space 123 of the frame structure 12, and the support member 3 can be directly limited, thereby ensuring the stability of the position of the support member 3 and the iron core 4 relative to the support member 3.

[0050] See Figure 1 In one embodiment of the present specification, the base 1 includes a pad 11 and a frame structure 12, the pad 11 forms a mounting plane 111, and the frame structure 12 is arranged on the mounting plane 111; the insulating member 2 is arranged on the mounting plane 111, and the support member 3 is arranged on the side of the insulating member 2 facing away from the mounting plane 111.

[0051] In this embodiment, the pad 11 is a plate-like structure, and the pad 11 forms a mounting plane 111 so that the frame structure 12 is set on the mounting plane 111, and the frame structure 12 and the mounting plane 111 together enclose an installation space 123. The insulating member 2 is arranged in the installation space 123 and abuts against the surface of the pad 11 facing the frame structure 12, and the support member 3 is arranged on the side of the insulating member 2 facing away from the mounting plane 111.

[0052] The cam 11 is provided with a plurality of support members 3 on the support plate 11, and the support members 3 are connected to the support plate 11 by the plurality of support members 3.

[0053] In the present application, the insulating part 2 and the support part 3 are limited and fixed by setting a frame structure 12, so that the insulating part 2 can be completely laid on the installation plane 111 of the pad 11, and then the support part 3 is placed on the surface of the insulating part 2 and limited in the installation space 123 of the frame structure 12, thereby avoiding the mutual abutment between the insulating part 2 and the support part 3 in the traditional installation method, and also avoiding the slot connection between the insulating part 2 and the support part 3 and the pad 11, thereby effectively reducing the installation difficulty of the pad structure 100 and effectively improving the production and installation efficiency.

[0054] See Figure 1 and Figure 2 In one embodiment of the present specification, the frame structure 12 includes a support plate 121 and a limiting member 122, the support plate 121 is arranged on the base plate 11; the limiting member 122 is connected to the support plate 121 and / or the installation plane 111, and the support plate 121 and the limiting member 122 enclose a mounting space 123.

[0055] It can be understood that the support plate 121 is the main supporting component of the frame structure 12. The support plate 121 is arranged on the pad 11. The support plate 121 is a plate-like structure. The plate surface of the support plate 121 can be perpendicular to the installation plane 111 of the pad 11, or it can be parallel to the installation plane 111 of the pad 11. Among them, the support plate 121 is connected to the pad 11 on the one hand. The support plate 121 can be fixedly connected to the pad 11, such as integral molding or welding, or it can be detachably connected, such as bolt connection, plug-in, etc. On the other hand, the support plate 121 can also be used to connect with the limit member 122 to fix the limit member 122 and form an installation space 123.

[0056] At the same time, the limiting member 122 can be a limiting plate, a limiting block, a limiting rod and other structures. The limiting member 122 can be directly set on the pad 11, or it can be only connected to the support plate 121, or it can be connected to the pad 11 and the support plate 121 respectively to form a frame structure 12 alone or together with the support plate 121. The limiting member 122 is set in the side area of ​​the pad 11. If the pad 11 is a rectangular pad 11, it has a longer length direction and a width direction perpendicular to the length direction, and the length of the pad 11 in the width direction is less than the length of the pad 11 in the length direction. The side area is located at the side of the pad 11 along the length direction.

[0057] It can be understood that by arranging the limit members 122 at the side of the pad 11, on the one hand, the plate width of the support plate 121 can be directly adapted to the width of the pad 11, which facilitates the direct installation of the support plate 121. On the other hand, the number and size of the limit members 122 can be changed to adapt to the length of the pad 11, and the size of the frame structure 12 can be reasonably set to accommodate transformer cores 4 of different sizes.

[0058] In one embodiment of the present specification, the limiting member 122 includes at least one of a limiting rod, a limiting plate, a limiting strip, and a limiting piece; it can be understood that the structure and form of the limiting member 122 are not limited, as long as it can form a frame structure 12 with the support plate 121, or it itself can be combined to form a frame structure 12, and can limit the insulating member 2 and the support member 3. The structural member is within the protection scope of this application, such as the limiting member 122 is a limiting rod, the limiting rod is a rod-shaped structure, one end of which is connected to the support plate 121, and the other end is connected to the pad 11, or it is connected to the pad 11 through multiple limiting rods to directly enclose the frame structure 12; or the limiting member 122 is a limiting plate, one side edge of the limiting plate is connected to the support plate 121, and the other side edge of the limiting plate is connected to the pad 11, so as to jointly enclose the frame structure 12; the limiting strips, limiting pieces and other structures such as limiting blocks, limiting ribs, etc. are the same and will not be repeated here.

[0059] Of course, the frame structure 12 can also be a structure including at least two of the above-mentioned limiting rods, limiting plates, limiting strips, limiting pieces, limiting blocks, and limiting ribs, such as staggered limiting strips and limiting rods to form a frame structure 12 of a frame structure, or in a direction perpendicular to the installation plane 111, the bottom is connected to the pad 11 with a limiting plate or limiting piece structure, and the upper part is connected to the limiting plate or limiting piece with a limiting rod or limiting strip structure, so that the bottom can more completely limit and fix the insulating part 2, and the upper part limits the side 32 of the support part 3, so as to simplify the frame structure 12 and reduce the use of materials for the frame structure 12 on the basis of ensuring the limiting fixation of the insulating part 2 and the support part 3, thereby simplifying the foot structure 100.

[0060] See Figure 1 and Figure 5 In one embodiment of the present specification, the insulating member 2 is an insulating plate, which is laid on the mounting plane 111, and the side wall of the insulating plate perpendicular to the mounting plane 111 is in contact with the support plate 121 and the limit member 122 at the same time; the support member 3 is provided on the side of the insulating plate facing away from the pad 11.

[0061] It can be understood that the insulating member 2 is a plate-like structure, and the insulating plate can be completely laid on the installation plane 111 and limited in the installation space 123, so that the insulating plate is perpendicular to part of the side wall of the installation plane 111, and can simultaneously abut against the surface of the support plate 121 and the surface of the limiting member 122, so that the frame structure 12 formed by the support plate 121 and the limiting member 122 can directly limit the installation of the insulating plate, effectively reducing the difficulty of installation and improving installation efficiency.

[0062] At the same time, the support member 3 is arranged on the side of the insulating plate facing away from the pad 11, so that the insulating member 2 and the support member 3 that originally needed to be connected to each other by clipping can realize the assembly of the pad structure 100. Now the insulating plate can be directly placed in the installation space 123, and the support member 3 can be directly placed on the side of the insulating plate facing away from the pad 11 to realize the assembly of the pad structure 100. There is no need for the insulating member 2 and the support member 3 to be aligned and abutted, and it is only necessary to limit them by the frame structure 12, which effectively reduces the difficulty of installation and improves the installation efficiency.

[0063] See Figure 5 In one embodiment of the present specification, a clearance groove 21 is provided on the edge of the insulating plate, and at least part of the groove wall of the clearance groove 21 abuts against the frame structure 12 to limit the insulating plate.

[0064] It can be understood that the limit member 122 is arranged on the side of the pad 11 along the length direction, and in order to ensure the compactness of the structure, the side wall of the limit member 122 facing away from the installation space 123 and the side wall of the pad 11 perpendicular to the installation plane 111 are maintained in the same plane, that is, the limit member 122 is aligned with the side of the pad 11. Based on this, when installing the insulating board, a clearance groove 21 is provided at part of the edge of the insulating board to avoid the limit member 122, so that the insulating board can be completely laid in the installation space 123, and the insulating board can be pressed against the limit member 122 through the groove wall of the clearance groove 21, and against the support plate 121 through the other side walls of the insulating board, so as to realize the installation and limitation of the insulating member 2 by the frame structure 12, thereby improving the installation firmness and convenience of the insulating member 2.

[0065] See Figure 2 and Figure 3In one embodiment of the present specification, the frame structure 12 includes a first frame 1a and a second frame 1b, and the first frame 1a and the second frame 1b are arranged at an interval; the foot structure 100 includes two support members 3, and the two support members 3 are respectively arranged on the first frame 1a and the second frame 1b.

[0066] In this embodiment, the first frame 1a and the second frame 1b are spaced apart on the pad 11, and the above-mentioned installation space 123 is formed between the first frame 1a and the second frame 1b. The transformer core 4 is arranged in the installation space 123, and the first frame 1a and the second frame 1b are respectively arranged on both sides of the transformer core 4. The pad structure 100 includes two support members 3, and the two support members 3 are respectively arranged in the installation space 123 formed by the first frame 1a and the second frame 1b to support the two side areas of the transformer core 4.

[0067] Specifically, two clamps 13 are spaced apart on the pad 11. The two clamps 13 are used to support and abut the iron core 4 of the transformer. The support plates 121 in the first frame 1a and the second frame 1b are respectively connected to the two clamps 13, so that the first frame 1a and the second frame 1b are spaced apart from each other.

[0068] It can be understood that the first frame 1a and the second frame 1b are two parts of the frame structure 12 and are arranged at intervals along a straight line so that the two support members 3 located in the first frame 1a and the second frame 1b can support the two side areas of the transformer core 4, thereby maintaining the stability of the transformer core 4, wherein the structures of the first frame 1a and the second frame 1b can be the same or different, and the first frame 1a and the second frame 1b are both supported by the above-mentioned support plate 121 and the limiting rod, limiting plate, limiting strip, limiting piece, At least one of the limiting ribs is connected in combination to be used for limiting the placement of a support member 3. At the same time, one end side wall of the insulating plate abuts against the first frame 1a, and the other end side wall of the insulating plate abuts against the second frame 1b, and the first frame 1a and the second frame 1b are limited in the clearance groove 21 formed on the end side wall of the insulating plate, so that the insulating plate is completely limited in the installation space 123 by the first frame 1a and the second frame 1b, reducing the installation difficulty of the insulating plate and the support member 3 and improving the installation efficiency of the insulating plate and the support member 3.

[0069] See Figure 2 and Figure 3 In one embodiment of the present specification, an escape space 1c is formed between the first frame 1a and the second frame 1b, the escape space 1c is connected to the installation space 123, and the escape space 1c is used to escape the iron core 4; two support members 3 are arranged on both sides of the escape space 1c.

[0070] It can be understood that an avoidance space 1c is also formed between the first frame 1a and the second frame 1b. Since the transformer core 4 includes multiple levels of parts with different sizes and specifications, and the central area has a larger structural size, an avoidance space 1c is set between the first frame 1a and the second frame 1b to avoid the transformer core 4 so that the transformer core 4 can be confined in the installation space 123. At the same time, in order to adapt to the structural characteristics of the transformer core 4 that gradually decreases from the middle to both sides, the limiting members 122 of the first frame 1a and the second frame 1b facing the transformer core 4 are also inclined, so that the height of the first frame 1a and the second frame 1b relative to the pad 11 is gradually reduced from the support plate 121 to the end facing each other, thereby facilitating the direct installation of the support member 3 and the core 4, and can play a good limiting and fixing role for the support.

[0071] The present application also proposes a transformer, which includes an iron core 4 and a foot structure 100. The support member 3 in the foot structure 100 is used to support the iron core 4. The specific structure of the foot structure 100 refers to the above embodiment.
