DETAILED DESCRIPTION

[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the directional words used, such as "upper" and "lower", are usually defined based on the drawing direction of the corresponding drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, specific orientation structure and operation, and therefore cannot be understood as limiting the present disclosure. "Inside" and "outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0028] As a first aspect of the present disclosure, Figures 1 to 4As shown, the present disclosure provides a cable fixing frame 100 for a box-type transformer, comprising a supporting structure 1 and a fixing structure 2, wherein one end of the supporting structure 1 is used to be connected to a concrete base 200 located below the box-type transformer, and the other end of the supporting structure 1 is connected to the fixing structure 2, the fixing structure 2 comprises a plurality of fixing members 21 for supporting cables 300, the fixing members 21 are used for passing the cables 300, and the cable fixing frame 100 is suitable for being arranged below the box-type transformer along the gravity direction.

[0029] Through the above technical solution, the fixing member 21 can fix the cable 300 on the fixed structure 2, the fixed structure 2 is connected to the supporting structure 1, and the supporting structure 1 is connected to the concrete base 200 located below the box-type transformer, thereby connecting the cable 300 to the concrete base 200, so that the gravity applied to the cable 300 is borne by the cable fixing frame 100, reducing the gravity applied to the cable 300 connector and the busbar of the box-type transformer, preventing the cable 300 connector from loosening or the busbar from deforming, and reducing the failure rate of the box-type transformer.

[0030] Alternatively, if Figure 3 As shown, the fixing structure 2 may further include a fixing rod 22, both ends of which are connected to the supporting structure 1 respectively, and a plurality of mounting holes 221 are formed on the fixing rod 22 at intervals along the length direction of the fixing rod 22, and a plurality of fixing members 21 are connected to the fixing rod 22 through the corresponding mounting holes 221, and the fixing members 21 and the fixing rod 22 can enclose to form a fixing hole 23, and the fixing hole 23 is used for the cable 300 to pass through, so as to fix the cable 300 on the fixing rod 22. A plurality of mounting holes 221 corresponding to the fixing members 21 are provided on the fixing rod 22, and the cable 300 is fixed to the fixing rod 22 through the fixing members 21, and a plurality of cables 300 can be fixed on the fixing rod 22 at the same time, so that the cable fixing frame 100 can meet the fixing requirements of a plurality of cables 300 in the box-type transformer.

[0031] Optionally, there may be multiple fixing rods 22, which are spaced apart along the width direction of the fixing rods 22, and each fixing rod 22 is formed with multiple mounting holes 221. Multiple fixing rods 22 can fix multiple cables 300, which can further improve the accommodation capacity of the cable fixing frame 100.

[0032] The present disclosure does not limit the specific structure of the fixing member 21. In an embodiment provided in the present disclosure, Figure 2 and Figure 4As shown, the fixing member 21 includes a pressing plate 211 and a connecting member 212. Through holes 2113 are formed at both ends of the pressing plate 211. The connecting member 212 is inserted through the through holes 2113 to fix the pressing plate 211 on the fixing rod 22. The pressing plate 211 is suitable for covering and pressing the cable 300. The connecting member 212 passes through the through holes 2113 and the mounting holes 221 in sequence to connect the pressing plate 211 with the fixing rod 22, so that the inner diameter of the fixing hole 23 is smaller than the outer diameter of the cable 300, thereby fixing the cable 300 on the fixing rod 22. In addition, the use of the pressing plate 211 to fix the cable 300 can also increase the contact area between the fixing member 21 and the cable 300, thereby reducing the pressure between the fixing member 21 and the cable 300, and preventing the cable 300 from being damaged or broken due to excessive local force while ensuring the fixing effect of the cable 300.

[0033] Optionally, the connecting member 212 may be a bolt and a nut, one end of the bolt sequentially passes through the through hole 2113 and the mounting hole 221 and is connected to the nut. The use of the bolt and the nut as the fixing member 21 can also adjust the distance between the pressing plate 211 and the fixing rod 22, thereby adjusting the aperture of the fixing hole 23 to accommodate cables 300 of different sizes.

[0034] In another embodiment provided by the present disclosure, the fixing member may have an arc segment, the arc segment may be combined with the fixing rod to form a fixing hole, the inner surface of the arc segment is used to fit the outer surface of the cable, and the two ends of the arc segment are respectively formed with external thread segments, and the external thread segments can pass through the mounting hole and connect with the bolt. The use of an integrated fixing member can reduce the difficulty of installing the fixing structure, and the arc segment that matches the shape of the outer surface of the cable can limit the position of the cable along the extension direction of the fixing rod, thereby further limiting the degree of freedom of the cable, so that the cable is fixed more firmly.

[0035] In order to further improve the fixing effect of the fixing member 21, optionally, as Figure 4 As shown, the pressing plate 211 includes a connected matching section 2112 and two connecting sections 2111. The two connecting sections 2111 are respectively connected to the two ends of the matching section 2112. A through hole 2113 is formed on the connecting section 2111. The matching section 2112 is constructed as an arc-shaped plate. The inner surface of the matching section 2112 is used to fit with the outer surface of the cable 300. The matching section 2112 and the fixing rod 22 enclose a fixing hole 23. During the fixing process, the two ends of the matching section 2112 are connected to the fixing rod 22 through the connecting section 2111. The inner surface of the matching section 2112 fits with the outer surface of the cable 300. The shape of the inner surface of the matching section 2112 matches the shape of the outer surface of the cable 300, which can limit the position of the cable 300 along the extension direction of the fixing rod 22, thereby further limiting the degree of freedom of the cable 300, so that the cable 300 is fixed more firmly.

[0036] Alternatively, if Figure 2 As shown, the fixing structure 2 may further include a buffer pad 24, which is used to be arranged between the inner surface of the matching section 2112 and the cable 300. Since the cable 300 has a large deadweight, the cable 300 is fixed by the matching section 2112 and the fixing rod 22. After a long period of use, the outer surface of the cable 300 is easily squeezed and deformed by the matching section 2112 and the fixing rod 22 under the action of gravity, affecting the electrical safety of the cable 300. By arranging the buffer pad 24 between the inner surface of the matching section 2112 and the cable 300, the pressure of the matching section 2112 on the outer surface of the cable 300 can be reduced, thereby extending the service life of the cable 300.

[0037] Alternatively, if Figure 3 As shown, the support structure 1 includes at least two support frames 11, and the two support frames 11 are arranged at intervals along the length direction of the fixing rod 22, and the two ends of the fixing rod 22 are respectively connected to the two support frames 11. The two support frames 11 are respectively supported at the two ends of the length direction of the fixing rod 22, so that there is space on the fixing rod 22 to arrange multiple cables 300. At the same time, supporting the fixing rod 22 on both sides can improve the stability of the fixing rod 22 and reduce the probability of the fixing rod 22 falling off due to force.

[0038] Here, it should be noted that the fixing rod 22 can be bolted or welded to the support frame 11, and the present disclosure does not limit this.

[0039] In one embodiment provided by the present disclosure, Figure 3 As shown, the support frame 11 includes a connecting rod 111, a supporting rod 112 and a reinforcing rod 113. The connecting rod 111 is used to be fixed on the concrete base 200 located below the box-type transformer, one end of the supporting rod 112 is connected to the connecting rod 111, and the supporting rod 112 is used to support the fixed structure 2. The reinforcing rod 113 is arranged obliquely, and the two ends of the reinforcing rod 113 are respectively connected to the supporting rod 112 and the connecting rod 111. The obliquely arranged reinforcing rod 113 can provide additional support for the supporting rod 112, so that the connection between the supporting rod 112 and the connecting rod 111 will not be broken due to the excessive weight of the cable 300, thereby improving the stability of the supporting structure 1.

[0040] The present disclosure does not limit the specific materials of the support structure 1 and the fixed structure 2. In one embodiment provided in the present disclosure, the connecting rod 111, the support rod 112, the reinforcing rod 113 and the fixed rod 22 are all angle steels. The angle steels can be used to form various load-bearing components according to different structural requirements, that is, the support frame 11 and the fixed rod 22 are formed by splicing and combination. In addition, the angle structure enables the angle steel to have good supporting strength. Under the same supporting strength, the angle steel is lighter, consumes less material, and saves costs.

[0041] As a second aspect of the present disclosure, the present disclosure provides a box-type transformer assembly, including a box-type transformer, a concrete base 200 and the above-mentioned cable fixing frame 100 for the box-type transformer, the box-type transformer is installed above the concrete base 200, a wiring room is provided in the concrete base 200, the cable fixing frame 100 is installed on the wall of the wiring room, and the cable 300 is fixed to the cable fixing frame 100.

[0042] The cable fixing frame 100 is installed in the connection room under the box-type transformer, so as to provide support for the cable 300 from the bottom of the box-type transformer, thereby reducing the force exerted by the cable 300 on the busbar and the cable 300 joint due to its own weight, preventing the busbar from being deformed and the cable 300 joint from being loosened, thereby extending the service life of the busbar of the box-type transformer and reducing the failure rate.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0045] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
