[0031] The present application provides a clamp structure.

[0032] Please refer to Figures 1 to 4 In an embodiment of the present application, the clamp structure is applied to a transformer 10, the transformer 10 includes a transformer body 100 and an outgoing line structure connected to the transformer body 100, the clamp structure includes a fixing member 210 and a wire fixing member 220, the fixing member 210 is used to be fixedly installed on the transformer body 100, the wire fixing member 220 is used to fix the outgoing line structure, at least one of the fixing member 210 and the wire fixing member 220 is provided with a mounting hole, the fixing member 210 and the wire fixing member 220 are connected through the mounting hole, and the mounting hole is configured as a strip-shaped hole 211.

[0033] Specifically, the transformer body 100 includes a core and a winding wound on the core, and the core is generally made of silicon steel sheet to reduce eddy current loss. The winding includes a high-voltage winding and a low-voltage winding. After the external current flows into the low-voltage winding of the transformer 10, it is converted into high-voltage current through electromagnetic induction, and the converted high-voltage current is output through the high-voltage winding, so as to realize the conversion of high voltage; or after the external current flows into the high-voltage winding of the transformer 10, it is converted into low-voltage current through electromagnetic induction, and the converted low-voltage current is output through the low-voltage winding, so as to realize the conversion of low voltage. The outgoing line structure includes a high-voltage main lead 320 and a high-voltage tapping lead 330 connected with the high-voltage winding, and further includes a low-voltage copper bar 310 connected with the low-voltage winding.

[0034] The fixing member 210 is used to be fixedly installed on the transformer body 100, and provides a mounting point for the wire fixing member 220, so that the wire fixing member 220 can be kept relatively fixed with the transformer body 100, thereby being able to fix the outgoing line structure, preventing the outgoing line structure from loosening due to vibration and the like during operation, affecting the electrical performance or causing safety hazards.

[0035] At least one of the fixing member 210 and the wire fixing member 220 is provided with a mounting hole. Both the fixing member 210 and the wire fixing member 220 can be provided with mounting holes, and the two are connected by fasteners; or one of the fixing member 210 and the wire fixing member 220 is provided with a mounting hole, and the other is provided with a protrusion that passes through the mounting hole; or the fixing member 210 is provided with a mounting hole, and the wire fixing member 220 is configured as a bolt that passes through the mounting hole and is pressed against the outgoing line structure by a nut.

[0036] The mounting hole is configured as a strip-shaped hole 211, so that the fixing member 210 and the wire fixing member 220 have a certain adjustment margin during installation, and the relative positions of the fixing member 210 and the wire fixing member 220 can be better adjusted to compensate for the deviation of the fixing position of the fixing member 210 from the transformer body 100, or the error of the processing size of the fixing member 210 and the wire fixing member 220, or the size deviation of the winding of the transformer body 100 after winding, so that the fixing member 210 and the wire fixing member 220 can be more flexibly connected together, thereby reducing the assembly difficulty of the fixing member 210 and the wire fixing member 220. In addition, the installation position of the wire fixing member 220 can also be adjusted according to the position of the outgoing line structure to avoid stress on the outgoing line structure, thereby optimizing the wiring process.

[0037] The technical solution of the present application configures the mounting hole as a strip-shaped hole 211, so that the fixing member 210 and the wire fixing member 220 can be effectively connected while having a certain adjustment margin, which can compensate for assembly errors and size errors of parts, thereby reducing the assembly difficulty of the fixing member 210 and the wire fixing member 220.

[0038] In an embodiment, referring to Figure 4 and Figure 6 , the length direction of the fixing member 210 is the first direction, the width direction is the second direction, the strip-shaped hole 211 is arranged on the fixing member 210 and extends along the first direction or the second direction.

[0039] Without loss of generality, the wire fixing member 220 is connected to the side of the fixing member 210 away from the transformer body 100, the strip-shaped hole 211 is arranged on the fixing member 210, and when the wire fixing member 220 is connected to the fixing member 210, the mounting hole of the wire fixing member 220 is more easily aligned with the strip-shaped hole 211 of the fixing member 210, thereby further reducing the assembly difficulty of the fixing member 210 and the wire fixing member 220.

[0040] The strip-shaped hole 211 can extend along the first direction (the length direction of the fixing member 210) or the second direction (the width direction of the fixing member 210). When the fixing member 210 is installed on the transformer body 100, the first direction can be consistent with the horizontal direction to adjust the relative position of the wire fixing member 220 and the fixing member 210 in the horizontal direction; the first direction can also be consistent with the vertical direction to adjust the position of the wire fixing member 220 and the fixing member 210 in the vertical direction; or the first direction can form an angle with the horizontal direction to adjust the position of the wire fixing member 220 and the fixing member 210 in both the horizontal direction and the vertical direction.

[0041] In other embodiments, the strip-shaped hole 211 is arranged on the wire fixing member 220.

[0042] In an embodiment, referring to Figure 4 and Figure 5 , the strip-shaped hole 211 extends along the first direction.

[0043] The strip-shaped hole 211 extends along the first direction, and the length of the strip-shaped hole 211 is greater, which can provide a larger adjustment range to facilitate large displacement adjustment.

[0044] In an embodiment, referring to Figure 5 , the strip-shaped hole 211 extends along the first direction, and a plurality of strip-shaped holes 211 are arranged along the second direction.

[0045] The wire fixing member 220 can be adjusted in the first direction through a single strip-shaped hole 211 or in the second direction through a plurality of strip-shaped holes 211, so that the fixing member 210 and the wire fixing member 220 can have adjustment margins in multiple directions, further reducing the assembly difficulty of the fixing member 210 and the wire fixing member 220.

[0046] In an embodiment, referring to Figure 6 and Figure 7 , the strip-shaped hole 211 extends along the second direction.

[0047] The strip-shaped hole 211 extends along the second direction, which can provide a more accurate adjustment range and is suitable for scenes requiring fine adjustment.

[0048] In an embodiment, referring to Figure 6 and Figure 7 , the strip-shaped hole 211 extends along the second direction, and a plurality of strip-shaped holes 211 are arranged along the first direction.

[0049] The wire fixing part 220 can be adjusted in the second direction through a single strip-shaped hole 211, or can be adjusted in the first direction through multiple strip-shaped holes 211, so that the fixing part 210 and the wire fixing part 220 can have adjustment margins in multiple directions, further reducing the assembly difficulty of the fixing part 210 and the wire fixing part 220.

[0050] In an embodiment, referring to Figures 1 to 3 , the length direction of the fixing part 210 is the first direction, and the width direction is the second direction. The fixing part 210 is provided in multiple, and the multiple fixing parts 210 are distributed along the second direction.

[0051] The multiple fixing parts 210 are distributed along the second direction, which can improve the stability and reliability of the connection between the clamping part structure and the transformer body 100, and can also improve the stability and reliability of the connection between the fixing part 210 and the wire fixing part 220. The multiple fixing parts 210 are distributed along the second direction, and more fixing parts 210 can be installed on the transformer body 100, and the selection range of setting different numbers of fixing parts 210 is larger.

[0052] In other embodiments, the multiple fixing parts 210 can also be distributed along the first direction.

[0053] In an embodiment, referring to Figures 1 to 3 , the wire fixing part 220 extends along the second direction, and one wire fixing part 220 is locked with multiple fixing parts 210 through fasteners.

[0054] One wire fixing part 220 is locked with multiple fixing parts 210 through fasteners, and the fixing part 210 and the wire fixing part 220 form multiple-point fixing, which can improve the stability of the connection between the fixing part 210 and the wire fixing part 220, and ensure that the wire fixing part 220 will not loosen due to vibration or other external forces during operation. Multiple fixing points can ensure that the stress between the wire fixing part 220 and the fixing part 210 is more uniform, avoiding local stress concentration, thereby reducing the risk of structural damage. Moreover, adjacent two fixing parts 210 and the wire fixing part 220 form a fixing area, and the two fixing parts 210 have a limiting effect on the outgoing line structure, so that the outgoing line structure is difficult to separate from the fixing area at both ends of the wire fixing part 220, thereby improving the fixing effect of the wire fixing part 220 on the outgoing line structure.

[0055] In other embodiments, the wire fixing part 220 can also be provided in multiple, and the multiple wire fixing parts 220 are connected one by one with the multiple fixing parts 210; or one wire fixing part 220 is connected with one fixing part 210.

[0056] The application further provides a transformer 10 comprising the clamp structure, the specific structure of which is described in the above embodiments, and the transformer 10 adopts all the technical solutions of the above embodiments, so that all the beneficial effects brought by the technical solutions of the above embodiments are achieved, which will not be repeated here.

[0057] In an embodiment, referring to Figures 1 to 3 , the clamp structure is provided with a plurality of clamp members 230, the length direction of the fixing member 210 is the first direction, the width direction of the fixing member 210 is the second direction, the clamp members 230 extend along the second direction, the fixing member 210 is arranged on the clamp members 230, and the clamp members 230 are arranged on both sides of the transformer body 100 in pairs to clamp the transformer body 100.

[0058] At least two clamp members 230 are arranged close to the upper end of the transformer body 100 and are arranged on both sides of the transformer body 100 in pairs, and the two clamp members 230 are connected by a screw rod to clamp the upper end of the transformer body 100; at least two clamp members 230 are arranged close to the lower end of the transformer body 100 and are arranged on both sides of the transformer body 100 in pairs, and the two clamp members 230 are connected by a screw rod to clamp the lower end of the transformer body 100. The fixing member 210 is arranged on the clamp members 230, and the fixing member 210 is arranged on the side of the clamp members 230 away from the transformer body 100 without loss of generality. Of course, in other embodiments, the fixing member 210 can also be connected to the lower side or the upper side of the clamp members 230.

[0059] In an embodiment, referring to Figure 8 , the clamp member 230 comprises a first body portion 231, and first flanges 232 are formed by folding the two side edges of the first body portion 231 in the width direction away from the transformer body 100, and the fixing member 210 is connected to the first flanges 232. The design of the first flanges 232 improves the structural strength of the clamp member 230. The clamp member 230 is simple in structure and easy to process.

[0060] In another embodiment, the clamp member 230 can also be in the form of a flat plate.

[0061] The fixing member 210 is simple in structure and easy to process.

[0062] In an embodiment, referring to Figure 2 and Figure 4 , the fixing member 210 is in the form of a flat plate, the fixing member 210 is arranged opposite to the first body portion 231, and the two side edges of the fixing member 210 in the first direction are flush with the first flanges 232 and are connected to the first flanges 232.

[0063] In another embodiment, referring to Figure 1 and Figure 5The fixing member 210 is flat, and is arranged opposite to the first main body 231. The two side edges of the fixing member 210 in the first direction protrude from the first flange 232 and are connected to the first flange 232.

[0064] In another embodiment, referring to Figure 3 and Figure 6 The fixing member 210 includes a second main body 212. The two side edges of the second main body 212 in the first direction are folded towards the transformer body 100 to form second flanges 213. The second main body 212 is arranged opposite to the first main body 231. The second flanges 213 can be stacked on the first flange 232 and connected to the first flange 232, or the edges of the second flanges 213 can be connected to the edges of the first flange 232. The design of the second flanges 213 improves the structural strength of the fixing member 210.

[0065] In another embodiment, referring to Figure 3 and Figure 7 The fixing member 210 includes a second main body 212. One side edge of the second main body 212 in the first direction is folded towards the transformer body 100 to form a second flange 213. The second flange 213 is stacked on the first flange 232 and connected to the first flange 232.

[0066] In an embodiment, referring to Figure 1 The plurality of clamping member structures include a first clamping member structure. The outgoing line structure includes a low-voltage copper bar 310 arranged corresponding to the first clamping member structure. The low-voltage copper bar 310 is arranged on the side of the fixing member 210 away from the clamping member 230. The first clamping member structure further includes at least one reinforcing plate 240. The reinforcing plate 240 is arranged on the clamping member 230 and is spaced apart from the fixing member 210 along the length direction of the clamping member 230.

[0067] The low-voltage copper bar 310 is used to connect the low-voltage winding of the transformer 10 and the low-voltage end of the external low-voltage power system, so as to introduce the low-voltage current into the low-voltage winding of the transformer 10. The wire fixing member 220 includes a third main body. The two side edges of the third main body in the first direction are folded towards the transformer body 100 to form third flanges. The low-voltage copper bar 310 is arranged on the side of the fixing member 210 away from the clamping member 230 and is clamped between the two third flanges, so as to fix the low-voltage copper bar 310. In other embodiments, the wire fixing member 220 can also be arranged in a sheet shape.

[0068] The low-voltage copper bar 310 is arranged in a substantially plate shape. The wire fixing member 220 has a better fixing effect on the low-voltage copper bar 310, and the number of the wire fixing member 220 is less than that of other outgoing line structures (the high-voltage main lead 320 or the high-voltage tapping lead 330), so that fewer fixing members 210 can be arranged.

[0069] The reinforcing plate 240 is arranged opposite to the first main body part 231 and is connected to the first flange 232 to reinforce the structural strength of the clamping member 230. The reinforcing plate 240 can be arranged at intervals at both ends of the clamping member 230, and the fixing member 210 is arranged between the reinforcing plates 240 at both ends; or the reinforcing plate 240 can be arranged at intervals alternately with the fixing member 210.

[0070] It is worth mentioning that the fixing member 210 is provided with a strip-shaped hole 211, so that the area of the fixing member 210 as a whole is increased, thereby the fixing member 210 also plays a role in reinforcing the structural strength of the clamping member 230, so that the reinforcing plate 240 can also not be arranged on some clamping members 230, thereby not only reducing the arrangement of the reinforcing plate 240, but also reducing the welding points formed by welding the reinforcing plate 240 and the clamping member 230, thereby simplifying the surface treatment process of the clamping member structure as a whole.

[0071] In an embodiment, referring to Figure 1 and Figure 2 , the clamping member 230 and the wire fixing member 220 extend along a second direction, and the fixing member 210 is distributed along the second direction and is provided with a strip-shaped hole 211. The strip-shaped hole 211 of the clamping member structure arranged close to the upper end of the transformer body 100 extends along the second direction, and the strip-shaped hole 211 of the clamping member structure arranged close to the lower end of the transformer body 100 extends along the second direction.

[0072] In an embodiment, the low-voltage copper bar 310 is arranged close to the lower end of the transformer body 100. The outgoing line structure further includes a high-voltage tapping lead 330 and a high-voltage main lead 320. The high-voltage tapping lead 330 is a wire connected to different taps of the high-voltage winding inside the transformer 10. The connection end of the high-voltage tapping lead 330 to the transformer body 100 is arranged on the same side of the transformer body 100 as the low-voltage copper bar 310 and close to the upper end of the transformer body 100. The connection end of the high-voltage main lead 320 to the transformer body 100 is arranged on the opposite side of the transformer body 100 and close to the upper end of the transformer body 100. The high-voltage main lead 320 is used to connect the high-voltage winding of the transformer 10 and an external high-voltage power system to transmit the converted high-voltage electrical energy of the transformer 10 to the next power distribution link. Of course, the high-voltage current of the external high-voltage power system can also be introduced into the high-voltage winding of the transformer 10 through the high-voltage main lead 320, converted into low-voltage current through electromagnetic induction, and then led out to an external low-voltage device or system through the low-voltage outgoing line structure.

[0073] The above only describes exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
