[0040] As mentioned in the background section, the transformer bushing is usually arranged on the tank of the transformer, so as to connect the coil winding in the tank with the terminal of the transformer bushing. The transformer bushing is fixedly connected with the tank through a flange and bolts, and a sealing gasket is arranged between the transformer bushing and the tank to enhance the air tightness and avoid the penetration of insulating oil into the tank.

[0041] However, during installation, one person needs to hold the bushing and align the mounting holes on the flange with the mounting holes on the tank, and another person needs to lock the bolts, so that at least two persons are needed to fix the transformer bushing on the tank, and the installation efficiency is low.

[0042] In view of the above problems existing in the prior art, the present application provides a bushing auxiliary installation structure, a transformer and a vehicle. The bushing auxiliary installation structure comprises a support member and a limiting assembly. The support member is used to abut against a box body of the transformer, and the support member has a limiting hole for accommodating part of the bushing. The limiting assembly is arranged on the support member, at least part of the limiting assembly corresponds to the limiting hole, and the limiting assembly is used to detachably connect with at least part of the bushing corresponding to the limiting hole, so as to fix the bushing on the box body. By abutting the support member against the box body, physical support is provided for the bushing. The limiting assembly is arranged on the support member and detachably connected with the bushing, so as to preliminarily fix the bushing on the box body. In this way, the function of auxiliary fixing of the bushing is achieved, so that the subsequent installation and fixing of the bushing can be completed by only one person, thereby improving the efficiency.

[0043] Hereinafter, an exemplary application scenario of the present application is introduced.

[0044] The bushing auxiliary installation structure provided by the present application can be applied to the transformer, so as to be used for auxiliary installation of the transformer bushing, such as the transformer on the bullet train. Specifically, the bushing auxiliary installation structure provided by the present application can achieve the function of auxiliary installation of the bushing, so that the subsequent installation and fixing of the bushing can be completed by only one person, thereby improving the efficiency.

[0045] Hereinafter, the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. Hereinafter, the embodiments of the present application will be described with reference to the drawings.

[0046] Referring to Figure 1 The bushing auxiliary installation structure 10 provided by the embodiments of the present application comprises a support member 100 and a limiting assembly 200.

[0047] The support member 100 is used to abut against the box body 30 of the transformer, and the support member 100 has a limiting hole 110 for accommodating part of the bushing 20. The limiting assembly 200 is arranged on the support member 100, at least part of the limiting assembly 200 corresponds to the limiting hole 110, and the limiting assembly 200 is used to detachably connect with at least part of the bushing 20 corresponding to the limiting hole 110, so as to fix the bushing 20 on the box body 30.

[0048] It can be understood that, referring to Figure 5As shown, the bushing 20 can include an insulating sleeve 21, a conductor 22, a first terminal 23 and a second terminal 24. The conductor 22 is arranged in the insulating sleeve 21, and the first terminal 23 and the second terminal 24 are arranged at two ends of the insulating sleeve 21 respectively and are electrically connected with the conductor 22 respectively. The box 30 of the transformer is provided with an outlet hole, the insulating sleeve 21 is inserted on the box 30 through the outlet hole, and the first terminal 23 is located in the box 30, so that the coil winding in the box 30 is electrically connected with the first terminal 23 and is sequentially led out through the second terminal 24 outside the box 30. The insulating sleeve 21 and the box 30 are fixed by the flange 25 and the bolts.

[0049] Referring to Figure 5 As shown, before assembly, the support 100 is abutted against the inner side of the box 30, and the first terminal 23 and part of the insulating sleeve 21 are located in the limiting hole 110 of the support 100. After aligning the fixing holes on the flange 25 with the mounting through holes on the box 30, at least part of the limiting assembly 200 corresponding to the first terminal 23 is connected, the limiting assembly 200 abuts against the support 100, so that the support 100 is fixedly abutted against the box 30, thereby preliminarily connecting and fixing the support 100, the box 30 and the bushing 20, and preliminarily fixing the bushing on the box 30, to facilitate the operation of locking the bolts subsequently. In this way, the installation and fixation of the bushing 20 can be completed by one person, thereby improving the efficiency.

[0050] After the bushing 20 is preliminarily fixed on the box 30 by the bushing auxiliary installation structure 10, the sealing ring can also be pressed tightly between the bushing 20 and the box 30, to avoid the shaking of the bushing 20 and prevent the dislocation and damage of the sealing ring.

[0051] Further, referring to Figure 5 As shown, the sealing ring and the flange 25 can be arranged on the outer side of the box 30, so as to avoid interference with the bushing auxiliary installation structure 10 and facilitate the operation. When the sealing ring is installed and pressed tightly on the outer side of the box 30 after the bushing auxiliary installation structure 10 preliminarily fixes the bushing 20 on the inner side of the box 30, the shaking of the bushing 20 can be avoided, thereby preventing the dislocation and damage of the sealing ring. When the bushing 20 and the box 30 are locked by the flange 25 and the bolts, the shaking of the bushing 20 can also be avoided, thereby improving the stability of the installation.

[0052] Of course, it can be understood that the bushing auxiliary installation structure 10 can also be arranged on the outer side of the box 30, i.e. the support 100 is abutted against the outer side of the box 30, and the second terminal 24 and part of the insulating sleeve 21 are located in the limiting hole 110 of the support 100, and then at least part of the limiting assembly 200 corresponding to the second terminal 24 is connected. In this way, the above technical effects can also be achieved, and further description is not continued.

[0053] Among them, at least part of the limiting components 200 corresponds to the limiting holes 110, part of the limiting components 200 may correspond to the limiting holes 110, or all of the limiting components 200 may correspond to the limiting holes 110. The embodiment of the present application does not impose too many restrictions on this.

[0054] The limiting assembly 200 is used to be detachably connected to at least a portion of the sleeve 20 corresponding to the limiting hole 110. After the sleeve 20 and the housing 30 are fixed via the flange 25, the limiting assembly 200 can be disconnected from the sleeve 20 to remove the support member 100 from the housing 30. Exemplarily, the detachable connection structure can be a threaded connection, a snap-fit ​​connection, or the like.

[0055] In summary, the sleeve auxiliary installation structure 10 provided in the embodiment of the present application provides physical support for the sleeve 20 by abutting the support member 100 against the box body 30. The limit assembly 200 is disposed on the support member 100 and is detachably connected to the sleeve 20 to achieve preliminary fixation of the sleeve 20 to the box body 30. This can assist in fixing the sleeve, so that subsequent installation and fixation of the sleeve 20 can be completed by only one person, thereby improving efficiency.

[0056] Reference Figure 1 and Figure 2 As shown, in some embodiments, the limiting assembly 200 includes a limiting member 210 and a connecting member 220 .

[0057] The limiting member 210 is arranged on the support member 100, and at least part of the limiting member 210 corresponds to the limiting hole 110. The limiting member 210 is used to abut against at least part of the sleeve 20 corresponding to the limiting hole 110, and the connecting member 220 is used to connect the limiting member 210 with the sleeve 20.

[0058] In the above embodiment, the portion of the limiting member 210 corresponding to the limiting hole 110 is used to abut against the sleeve 20, and the limiting member 210 and the sleeve 20 are connected together through the connecting member 220, so that the support member 100, the box body 30 and the sleeve 20 can be connected in sequence.

[0059] Among them, reference Figure 1 and Figure 5 As shown, the limiting member 210 can abut against the first terminal 23 of the sleeve 20 , and the connecting member 220 connects the limiting member 210 and the first terminal 23 to achieve a detachable connection between the limiting assembly 200 and the sleeve 20 .

[0060] Exemplarily, the connector 220 may be a bolt thread structure, a snap-fit ​​structure, a latch structure, a clamping structure, etc., and the embodiments of the present application do not impose too many restrictions on this.

[0061] Reference Figure 1 andFigure 2 As shown in some embodiments, the limiting member 210 is provided with a first through hole 2111 for accommodating part of the sleeve 20. The connecting member 220 is in abutment with the limiting member 210, and is used for detachable connection with the part of the sleeve 20 passing through the first through hole 2111.

[0062] In the above embodiments, the first through hole 2111 provided on the limiting member 210 can be used for accommodating the first wiring terminal 23 of the sleeve 20, so as to play a role of preliminary positioning. During installation, the first wiring terminal 23 of the sleeve 20 can pass through the first through hole 2111 on the limiting member 210, the connecting member 220 is in abutment with the side of the limiting member 210 away from the box 30, and then the connecting member 220 is connected with the first wiring terminal 23 passing through the first through hole 2111. In this way, the sleeve 20 can be preliminarily fixed on the box 30 in cooperation with the supporting member 100.

[0063] For example, the connecting member 220 can be a nut, a ring-shaped buckle or the like, and the connecting member 220 is in abutment with the side of the limiting member 210 away from the box 30, so as to limit the movement of the first wiring terminal 23 relative to the first through hole 2111.

[0064] Referring to Figure 1 As shown in some embodiments, the connecting member 220 is a nut.

[0065] In some embodiments, the connecting member 220 is a nut. Figure 1 and Figure 5 As shown in some embodiments, the first wiring terminal 23 of the sleeve 20 can be a wiring stud.

[0066] In the above embodiments, the nut is located on the side of the limiting member 210 away from the box 30, and the nut is threadedly connected with the wiring stud, so that the limiting member 210 abuts against the supporting member 100, and the supporting member 100 abuts against the box 30, thereby preliminarily fixing the sleeve 20 on the box 30.

[0067] Referring to Figure 1 and Figure 3 As shown in some embodiments, the supporting member 100 is provided with at least one mounting hole 120, and the limiting member 210 is arranged on the supporting member 100 through the mounting hole 120.

[0068] In the above embodiments, the mounting hole 120 is in communication with the limiting hole 110, and the limiting member 210 can be arranged on the supporting member 100 through the mounting hole 120, so that the limiting member 210 and the supporting member 100 can be conveniently detached and separated for storage.

[0069] Specifically, referring to Figure 1 and Figure 3As shown, two mounting holes 120 are arranged on the support 100, and two ends of the limiting member 210 are respectively inserted into the mounting holes 120.

[0070] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the limiting member 210 includes a main body part 211 and an extension part 212 connected with each other.

[0071] The main body part 211 is located in the limiting hole 110, a first through hole 2111 is arranged on the main body part 211, the extension part 212 extends to the outside of the limiting hole 110 through the mounting hole 120, and a limiting part 213 is detachably connected to the extension part 212, so as to limit the limiting member 210 on the support 100.

[0072] In the above embodiment, the main body part 211 of the limiting member 210 is mainly used for connecting with the connecting member 220 and the first wiring terminal 23, and the extension part 212 is used for penetrating through the mounting hole 120 of the support 100. The limiting part 213 is arranged on the extension part 212, which can be used to limit the limiting member 210 on the support 100, so as to avoid the limiting member 210 from falling off the support 100 through the mounting hole 120.

[0073] The extension part 212 and the main body part 211 can be an integral molding part, so as to facilitate processing, enhance the overall structural strength of the limiting member 210, ensure the stability of the preliminary fixation, and avoid breakage.

[0074] As shown in Figure 1 and Figure 2 The number of the extension part 212 can be two, and the two extension parts 212 are respectively located at two ends of the main body part 211, and the two extension parts 212 respectively extend to the outside of the limiting hole 110 through the mounting hole 120.

[0075] The limiting part 213 and the extension part 212 are detachably connected, so as to facilitate the assembly and disassembly between the limiting member 210 and the support 100, so as to timely repair and replace when the sleeve auxiliary installation structure 10 is damaged.

[0076] For example, the detachable connection structure between the limiting part 213 and the extension part 212 can be a threaded structure, a buckle structure, a bolt structure, etc., and the embodiments of the present application do not make too many limitations on this.

[0077] As shown in Figure 2 and FIG. 4, in some embodiments, the limiting part 213 and the support 100 have a first spacing, so that the limiting member 210 has a first activity space relative to the support 100.

[0078] In the above embodiment, there is a first distance between the limiting portion 213 and the support member 100, so that the limiting member 210 can move relative to the support member 100 along the length direction of the limiting member 210 to align with the first terminal 23 to reduce misalignment.

[0079] For example, the first spacing may be 10 mm to 20 mm. Specifically, the first spacing may be 15 mm.

[0080] There may be at least two limiting portions 213 . For example, as shown in FIG. 4 ( a ), there are two limiting portions 213 , which are located on the corresponding two extending portions 212 and outside the limiting hole 110 .

[0081] 4( b ) , there are two limiting portions 213 . The two limiting portions 213 are respectively located on the corresponding two extending portions 212 and are both located inside the limiting hole 110 .

[0082] 4 ( c ), there are two limiting portions 213 . Both limiting portions 213 are located on the same extension portion 212 . One limiting portion 213 is located inside the limiting hole 110 , and the other limiting portion 213 is located outside the limiting hole 110 .

[0083] Of course, in other embodiments, the number of the limiting portions 213 may be three, four, etc., and the arrangement thereof is the same as that of the two limiting portions 213 described above, which will not be further described here.

[0084] 4 ( d ), there may be one limiting portion 213 , which is provided on one of the extensions 212 . A positioning portion 214 is provided on the other extension 212 . The positioning portion 214 intersects with the extension 212 , and the size of the positioning portion 214 is larger than that of the mounting hole 120 .

[0085] Preferably, the positioning portion 214 is perpendicular to the extending portion 212 .

[0086] Reference Figure 1 and Figure 5 As shown, in some embodiments, the mounting hole 120 extends toward the direction close to the box body 30, and there is a second distance between the mounting hole 120 and the limiting member 210, so that the limiting member 210 has a second movable space relative to the support member 100, and the second movable space is located in the extension direction of the mounting hole 120 toward the box body 30.

[0087] In the above embodiment, when the sealing ring is assembled, the limiting member 210 can be moved in the second movable space to compress the sealing ring and prevent the sealing ring from being out of the groove and misplaced.

[0088] Exemplarily, the second distance can be 3mm~5mm. Specifically, the second distance can be 3mm.

[0089] Referring to Figure 1 and Figure 2 , in some embodiments, the extension part 212 has a second through hole 2121, and the limiting part 213 is arranged in the second through hole 2121.

[0090] In the above embodiments, the second through hole 2121 can be used to realize detachable connection of the extension part 212 and the limiting part 213, so as to facilitate operation.

[0091] Exemplarily, referring to Figure 2 and Figure 5 , the limiting part 213 can be a bent segment structure, which is arranged in the second through hole 2121 to limit the limiting part 210 on the support part 100. The limiting part 213 can also be a bolt and a nut, which are matched by the bolt passing through the second through hole 2121 to limit the limiting part 210 on the support part 100.

[0092] Further, the end of the extension part 212 is provided with at least one fillet, which can reduce stress concentration and prevent damage to other components or operators during assembly.

[0093] Referring to Figure 1 and Figure 3 , in some embodiments, the support part 100 is provided with at least one third through hole 130, which is in communication with the limiting hole 110.

[0094] In the above embodiments, the third through hole 130 is arranged on the support part 100, and the operator can observe the surface insulation of the insulating sleeve 21 of the sleeve 20, whether the connecting part 220 is damaged, whether the limiting part 210 is bent and deformed, and whether the connecting part 220, the limiting part 210 and the sleeve 20 are connected in place through the third through hole 130.

[0095] In addition, the third through hole 130 can also play a role in reducing weight.

[0096] It can be understood that the at least one third through hole 130 can be one. The number of third through holes 130 can also be multiple, and multiple third through holes 130 are arranged at intervals on the periphery of the support part 100. The embodiments of the application do not make too many limitations on this.

[0097] Referring to Figure 1 and Figure 3 , the support part 100 can be a cylindrical structure, and the number of third through holes 130 is 18, which are arranged in three layers, each layer having six third through holes 130 to form a ring array arrangement.

[0098] Exemplarily, the bottom surface diameter of the cylindrical structure can be 90mm ~ 110mm, the height can be 90mm ~ 100mm, and the diameter of the third through hole 130 can be 10mm ~ 15mm. Specifically, the bottom surface diameter of the cylindrical structure can be 98mm, the height can be 95mm, and the diameter of the third through hole 130 can be 12mm.

[0099] Exemplarily, the limiting piece 210 can be a rectangular body structure, the length can be 110mm ~ 130mm, the width can be 15mm ~ 20mm, the thickness can be 3mm ~ 6mm, the diameter of the first through hole 2111 can be 25mm ~ 35mm, and the diameter of the second through hole 2121 can be 5mm ~ 10mm.
