[0025] In the related art, most transformers need to use clamping members to clamp and fix the iron core so that the iron core can be stably installed inside the transformer to ensure the stable operation of the transformer. However, most clamping members are made of metal materials. When the transformer is operating, the clamping members are easily affected by the magnetic field generated by the transformer to generate a certain amount of eddy current, which affects the operating efficiency of the transformer to a certain extent and increases the energy consumption of the transformer; at the same time, under the action of the eddy current, it is easy to cause local overheating of the transformer, reducing the performance stability and service life of the transformer. To address the above problems, this application proposes a fixture structure 100.
[0026] Please refer to Figures 1 to 3 , in an embodiment of this specification, the fixture structure 100 includes a hoop member 10 and a fixing member 30. The hoop member 10 is provided with a surrounding space for the iron core 200 to pass through. The hoop member 10 is used to surround and clamp the outer peripheral side of the iron core 200; the fixing member 30 is connected to the hoop member 10, and the fixing member 30 is used to abut against the top surface of the iron core 200 and clamp and fix the iron core 200. Among them, the material of the hoop member 10 is a carbon fiber composite material, and the material of the fixing member 30 is a carbon fiber composite material.
[0027] It can be understood that the iron core 200 can be an integral structure formed by stacking multiple sheet materials or multiple block materials, so that the integral structure formed by the iron core 200 can have a top surface, a bottom surface, and side walls connecting the top surface and the bottom surface. The side walls can be set as the outer peripheral side of the iron core 200. In a transformer, it is usually necessary to use the fixture structure 100 to surround and clamp the iron core 200, and use the connection between the fixture structure 100 and the transformer housing to realize the installation and fixation of the iron core 200 on the transformer, effectively avoiding the shaking of the iron core 200 during transportation or use of the transformer, preventing the iron core 200 from spreading or deforming, and ensuring the stable and reliable operation of the iron core 200.
[0028] In this application, the fixture structure 100 can utilize the hoop member 10 to form a surrounding space that conforms to the shape of the iron core 200, enabling the hoop member 10 to provide a surrounding space for the iron core 200 to pass through, so that the hoop member 10 can be arranged to surround the outer periphery of the iron core 200, and the hoop member 10 can abut and clamp at least two opposite side walls of the iron core 200, achieving the clamping and fixing of the iron core 200 by the hoop member 10 in the horizontal direction. By using the fixing member 30 to abut against the top surface of the iron core 200 above the iron core 200 and making the fixing member 30 cooperate and connect with the hoop member 10, the clamping and fixing of the iron core 200 by the fixing member 30 in the vertical direction is achieved. Furthermore, the fixture structure 100 can be utilized to ensure the stable assembly of the iron core 200 on the housing of the transformer and prevent the iron core 200 from shifting during transportation or use. Among them, the hoop member 10 can be configured as a ring-shaped sleeve, multiple profile bars connected end to end, or a U-shaped hoop with an opening and closing member on one side, etc., and the fixing member 30 can be configured as a ring-shaped sleeve, a U-shaped clip, or a bundling wire, etc. In a transformer, the fixture structure 100 can be connected and fixed to the wall surface of the transformer housing by using the hoop member 10, or can be connected and fixed to the wall surface of the transformer housing by using the fixing member 30, or can be connected and fixed to the wall surface of the transformer housing by using both the hoop member 10 and the fixing member 30 at the same time, so that the transformer can utilize the fixture structure 100 to stably assemble the iron core 200 in the transformer housing and ensure the stable and reliable operation of the iron core 200 in the transformer.
[0029] At this time, by manufacturing the hoop member 10 from a carbon fiber composite material and also manufacturing the fixing member 30 from a carbon fiber composite material, the insulating physical properties of the carbon fiber composite material can be utilized to effectively avoid the influence of the magnetic field of the transformer on the fixture structure 100 and generate a certain amount of eddy current, thereby preventing the eddy current generated by the fixture structure 100 from affecting the power operation of the iron core 200, avoiding the increase in the operating energy consumption of the transformer and local heating, and ensuring the stable and reliable operation of the transformer. Moreover, the hoop member 10 and the fixing member 30 formed by manufacturing with carbon fiber composite materials have high mechanical properties, can meet better requirements for support stiffness, ensure the stable clamping and fixing of the iron core 200 by the fixture structure 100, and improve the structural stability and reliability of the fixture structure 100.
[0030] In related technologies, when a transformer uses clamping members such as steel to surround and fix the iron core 200, it is usually necessary to use insulating parts to be installed between the clamping members and the iron core 200 to achieve electrical isolation between the clamping members and the iron core 200, prevent current from acting on the housing of the transformer through the clamping members, and ensure the overall structural protection of the transformer. However, the setting of insulating parts will result in a relatively large overall occupied space of the clamping members and the iron core 200, and thus the overall structural volume of the transformer is relatively large.
[0031] Therefore, the fixture structure 100 made of carbon fiber composite material can utilize the physical property that the hoop member 10 and the fixing member 30 are insulated by themselves, reduce the setting of the insulating member between the fixture structure 100 and the iron core 200, which is beneficial to better reduce the occupied space of the fixture structure 100 and the iron core 200, and better realize the miniaturized design of the transformer structure. Moreover, the hoop member 10 and the fixing member 30 made of carbon fiber composite material have smaller weights, which is beneficial to better reduce the overall weight of the transformer, facilitate the transportation and installation of the transformer, and further improve the practicability and reliability of the fixture structure 100.
[0032] In an embodiment of the present specification, by making the hoop member 10 and the fixing member 30 of the fixture structure 100 made of carbon fiber composite material with high insulation and physical properties, the hoop member 10 and the fixing member 30 can stably clamp and fix the iron core 200. While restricting the horizontal movement and vertical lifting of the iron core 200 in the transformer, it can also effectively prevent the fixture structure 100 from generating eddy currents due to the magnetic field action of the transformer, effectively avoiding the increase in energy consumption and local heating of the transformer; at the same time, there is no need to set insulating materials between the fixture structure 100 and the iron core 200, effectively reducing the occupied space of the fixture structure 100 and the iron core 200 in the transformer, and further better reducing the overall structural volume of the transformer, realizing the miniaturized design of the transformer, and improving the practicability and reliability of the fixture structure 100.
[0033] Refer to Figure 2 and Figure 3 , in an embodiment of the present specification, the hoop member 10 includes two clamping beams 11 and two connecting structures; the two clamping beams 11 are arranged at intervals and are respectively used to abut against the opposite two side walls of the iron core 200; one connecting structure connects one ends of the two clamping beams 11, and the other connecting structure connects the other ends of the two clamping beams 11; the two connecting structures and the two clamping beams 11 enclose a surrounding space.
[0034] In this embodiment, the hoop member 10 may include two clamping beams 11 and two connecting structures. The length of the clamping beam 11 may be set to be greater than the horizontal length of the iron core 200, so that both ends of the clamping beam 11 can be exposed outside the iron core 200. By using the two clamping beams 11 to abut against the opposite side walls of the iron core 200 at intervals and using the connecting structure to fix both ends of the two clamping beams 11, the two clamping beams 11 can be moved closer to each other under the action of the connecting structure, realizing the clamping effect on the iron core 200 in the horizontal direction and preventing the iron core 200 from spreading. Among them, the connecting structure may be a buckle structure for clamping the two clamping beams 11, or may be a strap structure for bundling the ends of the two clamping beams 11, or may be a screw structure passing through the ends of the two clamping beams 11, etc. Both the clamping beam 11 and the connecting structure can be made of carbon fiber composite materials, so that the fixture structure 100 can better avoid being affected by the magnetic field of the transformer, ensure the clamping and fixing of the fixture structure 100 to the iron core 200, and further improve the practicability and reliability of the fixture structure 100.
[0035] Refer to Figure 2 and Figure 3 , in an embodiment of the present specification, the connecting structure is a first screw 13. The first screw 13 passes through the ends of the two clamping beams 11, and the nuts and bolts of the first screw 13 respectively abut against the two clamping beams 11.
[0036] In this embodiment, the connecting structure may adopt the structure of the first screw 13. One end of the first screw 13 may be provided with a nut, and the other end of the first screw 13 may be connected with a detachable nut. Both the first screw 13 and the nut can be made of carbon fiber composite materials. Furthermore, by opening through holes at the ends of the clamping beam 11, the first screw 13 can pass through the through holes at the ends of the two clamping beams 11, and the nut of the first screw 13 is abutted against one clamping beam 11, and the other end of the first screw 13 is connected with the nut to realize the fastening effect on the two clamping beams 11, ensuring the stable clamping effect of the hoop member 10 on the iron core 200 in the horizontal direction, and further improving the structural stability and reliability of the fixture structure 100. Among them, the hoop member 10 can use two or more first screws 13 to connect and fasten at the same end of the two clamping beams 11, which is beneficial to better improving the overall structural stability and reliability of the hoop member 10 and realizing a better clamping effect of the fixture structure 100 on the iron core 200.
[0037] Refer to Figure 2 , in an embodiment of the present specification, weight-reducing grooves 111 are respectively provided on the opposite sides of the two clamping beams 11 facing away from each other.
[0038] In this embodiment, the clamping beam 11 can be arranged with one side wall closely abutting against the outer periphery of the iron core 200, so as to better increase the contact area between the clamping beam 11 and the iron core 200, and better improve the clamping connection stability and reliability between the hoop member 10 and the iron core 200. By arranging a weight-reducing groove 111 on the side of the clamping beam 11 facing away from the iron core 200, that is, by respectively arranging weight-reducing grooves 111 in a concave manner on the sides of the two clamping beams 11 facing away from each other, the clamping beam 11 can be arranged in a structure similar to a C shape. Furthermore, the overall structure of the clamping beam 11 can be better simplified, which is beneficial to better reducing the production materials of the clamping beam 11, better reducing the production cost of the fixture structure 100, and further improving the practicability and reliability of the fixture structure 100.
[0039] Referring to Figure 1 and Figure 2 , in an embodiment of the present specification, the fixture structure 100 has an up-down direction. The fixture structure 100 includes two hoop members 10. The two hoop members 10 are arranged at intervals in the up-down direction. The hoop member 10 is provided with a connecting rod 15, and the connecting rod 15 connects the clamping beams 11 of the two hoop members 10.
[0040] In this embodiment, the direction perpendicular to the surface of the transformer housing for installing the iron core 200 can be set as the up-down direction. By arranging the fixture structure 100 with two hoop members 10, the two hoop members 10 can be arranged at intervals in the up-down direction. Furthermore, one hoop member 10 can be arranged adjacent to the top surface of the iron core 200, and the other hoop member 10 can be arranged adjacent to the bottom surface of the iron core 200, which is beneficial to better surrounding and clamping the iron core 200 under the action of the two hoop members 10, realizing a better clamping and fixing effect on the iron core 200 in the horizontal direction, and further improving the structural stability and reliability of the fixture structure 100. Among them, the distance between the two hoop members 10 can be set according to the structure such as the winding in the middle of the iron core 200. The two hoop members 10 can be arranged close to each other on the premise of ensuring the avoidance of the middle structure of the iron core 200, so that the fixture structure 100 can achieve a more stable clamping and fixing effect on the iron core 200.
[0041] Referring to Figure 1 and Figure 2 , in an embodiment of the present specification, the fixing member 30 includes a pressing plate 31 and a second screw 33. The pressing plate 31 abuts against the hoop member 10 and is used to abut against the top surface of the iron core 200; the second screw 33 passes through the pressing plate 31 and the hoop member 10 and connects the pressing plate 31 and the hoop member 10. The nut or screw cap of the second screw 33 abuts against the pressing plate 31.
[0042] In this embodiment, the fixing member 30 can use the pressing plate 31 to abut against the top surface of the iron core 200. The width of the pressing plate 31 can be set to be greater than the width of the iron core 200, so that both sides of the pressing plate 31 can be exposed outside the iron core 200 and located above the hoop member 10. At this time, a connecting rod 15 or a block structure can be arranged on the side of the pressing plate 31 facing the hoop member 10, or the two sides of the pressing plate 31 can be bent so that the pressing plate 31 can abut against the hoop member 10, so that there can be a certain force transmission relationship between the fixing member 30 and the hoop member 10, realizing a better clamping and fixing effect of the fixture structure 100 on the iron core 200.
[0043] In some embodiments, by using the second screw 33 to connect the pressing plate 31 and the hoop member 10, the end of the second screw 33 facing away from the pressing plate 31 can be connected to the housing of the transformer, so that the fixing member 30 can stably press the iron core 200 against the housing of the transformer under the fastening action of the second screw 33 on the pressing plate 31, realizing the stable assembly of the iron core 200 and preventing the iron core 200 from moving in the vertical direction. At this time, a nut can be arranged at one end of the second screw 33, and a detachable nut can be connected at the other end. The second screw 33 can pass through the housing, the hoop member 10 and the pressing plate 31 from bottom to top, and the nut of the second screw 33 can abut against the housing, so that the nut of the second screw 33 abuts against the pressing plate 31 and fastens the pressing plate 31; or, the second screw 33 can pass through the pressing plate 31, the hoop member 10 and the housing from top to bottom, the nut of the second screw 33 abuts against the pressing plate 31, and a nut is used to connect the second screw 33 on the housing and abut against the housing to realize the fastening of the pressing plate 31, further improving the overall structural stability and reliability of the fixture structure 100.
[0044] Among them, both the pressing plate 31 and the second screw 33 can be made of carbon fiber composite materials, so that the fixture structure 100 can better avoid being affected by the magnetic field of the transformer and ensure the stable clamping and fixing effect of the fixture structure 100 on the iron core 200.
[0045] Refer to Figure 1 and Figure 2 , in an embodiment of this specification, a first limiting groove 311 is provided on one side of the pressing plate 31. The inner wall of the groove of the first limiting groove 311 is used to abut against the top surface of the iron core 200. First flanges 313 are respectively provided on opposite sides of the pressing plate 31. The first flanges 313 abut against the hoop member 10, and the second screw 33 passes through the first flanges 313.
[0046] In this embodiment, the pressing plate 31 can be recessed on the side facing the iron core 200 to form a first limiting groove 311. When the pressing plate 31 fixes the iron core 200, a part of the top structure of the iron core 200 can pass through the notch of the first limiting groove 311 and be located within the first limiting groove 311, so that the top surface of the iron core 200 can abut against the inner wall of the groove of the first limiting groove 311. Thus, the first limiting groove 311 can better play a role in limiting and clamping the iron core 200, which is beneficial to better restricting the movement of the iron core 200 in the horizontal and vertical directions, and further improving the clamping and fixing effect of the fixture structure 100. At this time, the opposite sides of the pressing plate 31 can be bent outwards respectively to form first flanges 313, which can be used to abut against the hoop member 10, and the second screw 33 passes through the first flanges 313 and the hoop member 10, so that the fixing member 30 and the hoop member 10 can better contact and transmit force with each other, realizing a better clamping and fixing effect of the fixture structure 100 on the iron core 200, and further improving the structural stability and reliability of the fixture structure 100.
[0047] Refer to Figure 1 and Figure 2 , in an embodiment of the present specification, the fixing member 30 further includes a support plate 35. The support plate 35 is arranged at an interval with the pressing plate 31 and abuts against the hoop member 10. The support plate 35 is used to abut against the bottom surface of the iron core 200, and the second screw 33 passes through the pressing plate 31, the hoop member 10 and the support plate 35 in sequence.
[0048] In this embodiment, the fixing member 30 can also use the support plate 35 to abut against the bottom surface of the iron core 200, and use the second screw 33 to pass through and connect the pressing plate 31, the hoop member 10 and the support plate 35 in sequence. The pressing plate 31 and the support plate 35 can be used to clamp the iron core 200 in the vertical direction, realizing a more stable installation and fixing effect of the fixture structure 100 on the iron core 200. In addition, when the fixture structure 100 installs and fixes the iron core 200 on the shell of the transformer, the support plate 35 can be used to stably support and isolate the iron core 200 from the shell, avoiding direct contact between the iron core 200 and the shell. At the same time, the support plate 35 made of carbon fiber composite material can realize a certain insulation effect between the iron core 200 and the shell, effectively avoiding electrical contact between the iron core 200 and the shell, and ensuring the overall structural stability of the transformer.
[0049] Refer to Figure 1 and Figure 2 , in an embodiment of the present specification, a second limiting groove 351 is provided on one side of the support plate 35. The inner wall of the groove of the second limiting groove 351 is used to abut against the bottom surface of the iron core 200. Second flanges 353 are provided on the opposite sides of the support plate 35 respectively, and the second screw 33 passes through the second flanges 353.
[0050] In this embodiment, the support plate 35 can be recessed on the side facing the iron core 200 to form a second limiting groove 351. When the support plate 35 fixes the iron core 200, a part of the bottom structure of the iron core 200 can pass through the notch of the second limiting groove 351 and be located within the second limiting groove 351, so that the bottom surface of the iron core 200 can abut against the inner wall of the groove of the second limiting groove 351. Furthermore, the second limiting groove 351 can better play a role in limiting and clamping the iron core 200, which is beneficial to better restricting the movement of the iron core 200 in the horizontal and vertical directions, and further improving the clamping and fixing effect of the fixture structure 100. At this time, the opposite sides of the support plate 35 can be bent outwards respectively to form second flanges 353, and the second flanges 353 can be used for the second screw 33 to stably pass through and connect the hoop member 10 and the pressing plate 31, ensuring the stable assembly of the fixture structure 100 and further improving the structural stability and reliability of the fixture structure 100.
[0051] In addition, the second flange 353 can abut against the hoop member 10. By using the mutual contact between the second flange 353 and the hoop member 10, better force transmission between the fixing member 30 and the hoop member 10 can be realized, ensuring a better clamping and fixing effect of the fixture structure 100 on the iron core 200, and further improving the structural stability and reliability of the fixture structure 100.
