Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Oil-filled cable terminals require the filling of insulating oil during installation, therefore they are typically installed vertically. If the terminal is horizontal, the insulating oil will be difficult to fill, and leakage is possible. Consequently, the installation of fully dry-type cable terminals on brackets suitable for oil-filled terminals is significantly limited and difficult to manage. For example, the weight of high-voltage cables, coupled with the presence of terminal components, makes it difficult to erect the cable terminal before assembling it with the bracket.

[0034] The dry-type cable terminal has a top at one end and a bottom at the other; the top has components such as a tightening ring, a pressure cap, and a top cover; the bottom has components such as a connecting flange and a supporting insulator.

[0035] Reference Figure 1 and Figure 5 As shown, a fixing bracket for cable terminals according to an embodiment of the present invention includes a frame assembly 100, a first support frame 200, and a second support frame 300.

[0036] The frame assembly 100 lies within a first plane; a first support frame 200 is connected to the frame assembly 100 and lies within a second plane, which is perpendicular to the first plane. The first support frame 200 has multiple first connecting holes 201, which are distributed circumferentially within the second plane. The structure of the first support frame 200 is as follows: Figure 2 As shown.

[0037] The fully dry cable termination can be parallel to the first plane, that is, parallel to the frame assembly 100. The cable termination is passed through the first support frame 200, and its position is adjusted so that the bottom of the cable termination is within the first support frame 200. Bolts are then passed through the first connecting hole 201 to fix the cable termination to the first support frame 200. For example, the connecting flange of the cable termination mates with the first support frame 200 and is connected by bolts.

[0038] The second support frame 300 is connected to the frame assembly 100. The second support frame 300 is located in a third plane, which is parallel to the second plane. The second support frame 300 is provided with a plurality of second connecting holes 301, which are distributed circumferentially within the third plane. The structure of the second support frame 300 is as follows: Figure 3 As shown.

[0039] When designing the mounting bracket, the distance between the second support frame 300 and the first support frame 200 can be determined according to the dimensions of the cable terminal to be installed, so that when the bottom of the cable terminal is fixed to the first support frame 200, the top of the cable terminal is located at the second support frame 300. Similarly, the top of the cable terminal is also connected to the second support frame 300 by bolts, and the second connecting hole 301 provides a mounting position for the bolts.

[0040] It is important to understand that since fully dry cable terminals do not require internal insulation oil filling, they can be placed at an angle. During installation, the frame assembly 100 can be placed horizontally first, with the first plane parallel to the horizontal plane, facilitating worker adjustment of the relative position between the cable terminal and the first support frame 200 or the second support frame 300. Furthermore, the bottom of the cable terminal can be connected to the first support frame 200 first, followed by the top of the cable terminal to the second support frame 300. To facilitate cable terminal installation, the second support frame 300 can also be designed to connect to the frame assembly 100 via bolts. After the bottom of the cable terminal is installed, the second support frame 300 can be passed through the top of the cable terminal, completing the connection between the second support frame 300 and the frame assembly 100, as well as the connection between the second support frame 300 and the top of the cable terminal.

[0041] Furthermore, in order to improve the structural strength between the second support frame 300 and the frame assembly 100, the second support frame 300 and the frame assembly 100 can be fixedly connected, for example by welding.

[0042] At this time, in order to facilitate the installation of cable terminals, it is understood that the frame assembly 100 includes a first frame 110 and a second frame 120. Both the first frame 110 and the second frame 120 are located in a first plane. The first frame 110 and the second frame 120 are spliced ​​together. The first support frame 200 is connected to the first frame 110 and the second support frame 300 is connected to the second frame 120.

[0043] In the above embodiment, after the bottom of the cable terminal is fixedly connected to the first support frame 200, the second support frame 300 is passed through the top of the cable terminal, and the second frame 120 is spliced ​​with the first frame 110 to complete the assembly of the frame assembly 100. Subsequently, the installation between the top of the cable terminal and the second support frame 300 can be completed.

[0044] It is understood that the frame component 100 also includes a third frame 130, which is located in the first plane. The third frame 130 is spliced ​​with the first frame 110 and the second frame 120 respectively, and the third frame 130 is located between the first frame 110 and the second frame 120.

[0045] The frame assembly 100 is divided into a first frame 110, a second frame 120, and a third frame 130. Besides facilitating the connection between the first support frame 200, the cable terminal, and the second support frame 300, it also helps to distribute the stress on the frame assembly 100. Especially when the distance between the first support frame 200 and the second support frame 300 is long, resulting in an excessively long frame assembly 100, if the frame assembly 100 only includes the first frame 110 and the second frame 120, and the first frame 110 and the second frame 120 are connected by bolts, then the bolts at that point may be subjected to excessive stress, leading to structural failure. After adding the third frame 130, the third frame 130 can be set between the first frame 110 and the second frame 120. Then the frame assembly 100 has bolt connection points between the first frame 110 and the third frame 130, as well as bolt connection points between the third frame 130 and the second frame 120. Increasing the number of bolt connections can distribute the stress of the frame assembly 100 to each bolt connection point, reducing the risk of structural failure at the bolt connection points.

[0046] It is understandable that the first support frame 200 includes multiple plates 210, which are connected end to end and arranged in a square shape.

[0047] The first support frame 200 is assembled from multiple plates 210, which facilitates the transportation of the fixed bracket. A single plate 210 occupies less space than a complete first support frame 200, and multiple plates 210 can be stacked for transport. Upon arrival at the installation site, the plates 210 are assembled to form the first support frame 200. The square first support frame 200 formed by assembling the plates 210 provides good structural strength. It should be understood that the individual plates 210 can be assembled using bolts or welded to enhance structural strength; however, welding hinders subsequent disassembly and maintenance. Preferably, the multiple plates 210 are connected by bolts.

[0048] It should be understood that the second support frame 300 can also adopt the same structural design as the first support frame 200, that is, the second support frame 300 can also be assembled using multiple plates.

[0049] It is understood that the first support frame 200 is provided with two first stiffening plates 220. The first stiffening plates 220 are located at the corners of the first support frame 200, and the two first stiffening plates 220 are connected to the same side of the first support frame 200, which is the side where the first support frame 200 is connected to the frame assembly 100.

[0050] Since the first support frame 200 is used to connect the bottom of the cable terminal, it is subjected to greater forces than the second support frame 300, making it more prone to deformation. Providing a first stiffening plate 220 on the first support frame 200 strengthens its structural strength and reduces the risk of deformation.

[0051] It should be understood that, if necessary, the second support frame 300 can also be equipped with a similar stiffening plate structure. Furthermore, to facilitate adjustment of the installation position of the cable terminal, a positioning plate can also be provided on the second support frame 300. The positioning plate is used to limit the position of the top of the cable terminal, specifically, it can limit the top cover of the cable terminal.

[0052] It is understood that a plurality of second stiffeners 230 are provided between the first support frame 200 and the frame assembly 100, and the second stiffeners 230 are located at the corners formed between the first support frame 200 and the frame assembly 100.

[0053] It is important to understand that during cable termination assembly, the frame assembly 100 can be placed horizontally, i.e., the first plane is parallel to the horizontal plane, facilitating the adjustment and installation of the cable termination. After the cable termination is installed, the frame assembly 100 can also be adjusted to other orientations for installation and fixation. For example, the frame assembly 100 can be installed and fixed vertically, i.e., the first plane is parallel to the vertical plane. In this case, the second and third planes are turned to be parallel to the horizontal plane. Both the first support frame 200 and the second support frame 300 are subjected to bending moments. To enhance the structural strength of the first support frame 200, multiple second stiffening plates 230 are provided, located at the corners formed between the first support frame 200 and the frame assembly 100.

[0054] Similarly, in order to enhance the structural strength of the second support frame 300, a stiffening plate structure similar to the second stiffening plate 230 can be provided, which is used to set at the corner formed between the second support frame 300 and the frame assembly 100.

[0055] Reference Figure 4 As shown, it can be understood that the system also includes a cable support assembly 400, which is connected to the frame assembly 100. The cable support assembly 400 is located on the side of the first support frame 200 away from the second support frame 300. The cable support assembly 400 has a support surface that is parallel to the first plane.

[0056] Reference Figure 6 As shown, when installing the cable terminal, the frame assembly 100 is placed horizontally, and the cable is connected to the bottom end of the cable terminal. The cable support assembly 400 can be used to support the cable of the cable terminal, reducing the stress on the first support frame 200 during installation.

[0057] It is understood that the cable support assembly 400 includes a third support frame 410, a diagonal brace frame 420, and a support plate 430. The third support frame 410 is connected to the frame assembly 100. The support plate 430 is fixed to the side of the third support frame 410 away from the frame assembly 100. The support surface is located on the plate surface of the support plate 430. One side of the diagonal brace frame 420 is connected to the support plate 430, and the other side of the diagonal brace frame 420 is connected to the frame assembly 100. The plane where the diagonal brace frame 420 is located intersects the plane where the third support frame 410 is located.

[0058] The third support frame 410 can be perpendicular to the frame assembly 100, acting as a column. The diagonal brace frame 420 intersects with the third support frame 410, thus acting as a diagonal brace. As long as the support plate 430 is parallel to the first plane, the support surface on the support plate 430 can support the cable. Furthermore, when the frame assembly 100 is divided into a first frame 110, a second frame 120, and a third frame 130, a fourth frame can also be provided. The fourth frame is connected to the first frame 110, and the third support frame 410 can be fixed to the fourth frame. It should be understood that in some embodiments, a cable fixing clip can also be provided on the support plate 430 to clamp and fix the cable.

[0059] Understandably, the cable support assembly 400 is generally used to provide auxiliary support for the cable during cable terminal installation. When the frame assembly 100 is installed vertically, as... Figure 7 As shown, the cable support assembly 400 no longer serves to support the cable, so the cable support assembly 400 and the frame assembly 100 are preferably connected by bolts. After the cable terminal is installed and the frame assembly 100 is placed vertically, the cable support assembly 400 can be disassembled for subsequent reuse.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
