Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to cable tray supports, cable support mechanisms and power equipment. Background Technology

[0002] Transformers play a vital role in power systems, and their normal operation directly affects the stability of the entire power grid. During transformer operation, a large number of cables need to be laid. These cables are typically used to connect electrical equipment on the high-voltage and low-voltage sides to ensure the transmission and distribution of electrical energy. However, due to the large number and length of these cables, a lack of proper support and securing can affect the safe operation of the transformer and the entire power system.

[0003] Currently, cable support mechanisms are commonly used to support and fix cables. These mechanisms include brackets and cable trays. During installation, workers first need to mark the bracket positions on the transformer tank cover according to the design drawings and then weld the brackets one by one according to the markings. However, positional deviations may occur during the placement and welding of the brackets, reducing the straightness of the arrangement of multiple brackets. This deviation makes it difficult to align the mounting holes on the cable tray with the mounting holes on the brackets, increasing installation difficulty and even affecting the stability of the cable tray.

[0004] Therefore, there is an urgent need for a cable tray support, cable support mechanism, and power equipment to solve the above problems. Utility Model Content

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0050] This embodiment provides a cable tray bracket, a cable support mechanism, and electrical equipment. The electrical equipment includes a transformer and a cable support mechanism. The cable support mechanism is installed on the transformer, and the transformer's cables are housed within the cable support mechanism. The cable support mechanism not only facilitates the safe and orderly laying of cables but also prevents cable damage due to factors such as compression, friction, or moisture, thereby ensuring the stable operation of the entire electrical system.

[0051] The following describes the specific details of a cable support mechanism, using the example of a cable support mechanism used to support the cables of a transformer. It is understood that in other embodiments, the cable support mechanism can also be applied in other scenarios requiring cable support, such as power equipment including reactors and cable support mechanisms, where the cable support mechanism supports the cables connected to the reactor, etc.

[0052] The cable support mechanism includes a cable tray and a cable tray bracket. The cable tray bracket is mounted on the transformer and also on the transformer's tank cover. The cable tray is mounted on the cable tray bracket, and the transformer's cables are installed inside the cable tray. The cable tray has mounting holes for securing it to the cable tray bracket. It should be noted that the cable tray can be any type of existing technology.

[0053] like Figures 1-5As shown, the cable tray support includes a support assembly 100 and a positioning assembly 200. The support assembly 100 is provided with a mounting part 111 that cooperates with the cable tray. The cable tray is mounted on the mounting part 111. The positioning assembly 200 includes a connecting plate 210, a first pipe fitting 220, and a positioning rod 230. The connecting plate 210 is elastically connected to the support assembly 100. The first pipe fitting 220 and the positioning rod 230 are coaxially arranged on the side of the connecting plate 210 away from the support assembly 100. The side wall of the first pipe fitting 220 is provided with an observation port 221. The end of the positioning rod 230 away from the connecting plate 210 is flush with the end face of the first pipe fitting 220 and is located within the field of view of the observation port 221. When the construction personnel place the support component 100, they can visually observe through the observation window whether the positioning rod 230 is aligned with the marking point on the oil tank cover (i.e., the part to be installed 111), ensuring the accuracy of the entire cable tray bracket installation position. On the one hand, this ensures the positional accuracy of the installation part 111 on the support component 100, that is, the coaxiality of the installation part 111 and the installation hole on the cable tray. On the other hand, in the scenario where multiple cable tray brackets support cable trays at the same time, it can ensure the straightness of the arrangement of multiple cable tray brackets, thereby ensuring the accurate and firm installation of the cable tray. In addition, the positioning rod 230 is fixed on the connecting plate 210, and the connecting plate 210 is elastically connected to the support component 100, which can also absorb the vibration and stress generated during the welding process to a certain extent, improving the welding quality of the support component 100.

[0054] Optionally, such as Figure 1 As shown, the observation port 221 is located at the end of the first pipe fitting 220 away from the connecting plate 210 (i.e., the observation port 221 is located at the end of the first pipe fitting 220), which makes it easier for construction personnel to see the alignment status of the positioning rod 230 with the marking point more intuitively, thus improving the convenience of construction.

[0055] Optionally, such as Figure 2 and Figure 3 As shown, the observation port 221 can be a slot located at the end of the first pipe fitting 220, providing a wider field of view and improving the convenience of observation. In this embodiment, the slot is a U-shaped slot, with two U-shaped slots symmetrically arranged radially along the first pipe fitting 220. This facilitates construction personnel in checking whether the positioning rod 230 is aligned with the marking point from different angles, effectively reducing construction errors and improving installation efficiency.

[0056] In one embodiment, the observation port 221 can be a through hole, which avoids the local stress concentration problem that may occur after the first pipe 220 is slotted, so that the first pipe 220 maintains higher strength and improves the long-term load-bearing capacity of the support assembly 100. Optionally, the through hole can be set in the middle of the first pipe 220 to maintain the overall strength of the first pipe 220, reduce stress concentration, and improve the long-term load-bearing capacity.

[0057] In another embodiment, a slot and a through hole can be opened on the side wall of the first pipe fitting 220. The slot is used to provide a wide field of view, so that construction personnel can visually check the alignment of the positioning rod 230 with the marking point from different angles, while the through hole helps to alleviate local stress concentration and improve the overall strength and long-term load-bearing capacity of the first pipe fitting 220.

[0058] Optionally, such as Figure 3 As shown, in this embodiment, the positioning rod 230 is a positioning pin, that is, the lower end of the positioning rod 230 has a pointed tip, which makes it easy for the positioning rod 230 to be aligned with the marking point. In other embodiments, the lower end surface of the positioning rod 230 can be a plane, which helps to improve the stability of the positioning rod 230.

[0059] Optionally, the support assembly 100 includes a support plate 110 and a second pipe fitting 120. The mounting part 111 is disposed on the support plate 110, and the second pipe fitting 120 is connected to the support plate 110. A shock-absorbing structure 300 is provided inside the second pipe fitting 120. The connecting plate 210 is elastically connected to the support assembly 100 through the shock-absorbing structure 300. The shock-absorbing structure 300 enables the positioning assembly 200 to float axially and radially in the second pipe fitting 120, absorbing some of the impacts and vibrations generated during installation, reducing stress concentration caused by thermal expansion during welding, and improving welding quality and service life.

[0060] like Figure 1 As shown, the mounting portion 111 includes at least one circular through hole. Based on the precise positioning of the support assembly 100, setting the mounting portion 111 as a circular through hole ensures that the mounting holes on the cable tray align with it, thereby improving the processing convenience of the support assembly 100 and reducing manufacturing costs. Optionally, in this embodiment, the support assembly 100 is provided with two circular through holes. In other embodiments, the specific number of circular through holes can be flexibly set as needed, and is not specifically limited here.

[0061] Optionally, such as Figure 4 As shown, the support plate 110 is provided with an annular groove 112. One end of the second pipe fitting 120 is embedded in the annular groove 112, and then the second pipe fitting 120 is firmly connected to the support plate 110 by welding. The annular groove 112 ensures the accuracy of the installation position of the second pipe fitting 120 and ensures a more secure connection between the second pipe fitting 120 and the support plate 110.

[0062] Optionally, such as Figure 5As shown, the damping structure 300 includes a sliding plate 310, a first damping component 320, a third pipe 330, and a second damping component 340. The sliding plate 310 is slidably disposed within the second pipe 120 along the axial direction. One end of the first damping component 320 is connected to the sliding plate 310, and the other end elastically abuts against the support plate 110 along the axial direction of the second pipe 120. The third pipe 330 is disposed on the side of the sliding plate 310 away from the support plate 110. One end of the second damping component 340 is connected to the outer wall of the third pipe 330, and the other end elastically abuts against the inner wall of the second pipe 120 along the radial direction. This provides elastic buffering and damping effects for the positioning component 200 in the axial and radial directions of the support component 100. After welding, when the cable tray support is subjected to vibration in different directions, the damping structure 300 can buffer and absorb the force, reduce the impact directly transmitted to the welding point, and prevent fatigue cracking of the weld.

[0063] Optionally, such as Figure 5 As shown, the first damping component 320 includes a first rod 321 and a first elastic element 322. The first rod 321 is axially mounted on the sliding plate 310 along the second pipe 120. The first elastic element 322 is sleeved on the first rod 321, with one end abutting against the sliding plate 310 and the other end abutting against the support plate 110. The first damping component 320 has a simple structure, enhances the axial buffering capacity of the cable tray support, and improves the seismic and impact resistance of the cable tray support. Furthermore, when subjected to external forces or welding thermal expansion and contraction, the first elastic element 322 can provide axial flexible buffering, reducing stress concentration at the weld and preventing structural deformation or cracking due to welding stress.

[0064] Optionally, such as Figure 5 As shown, the second damping component 340 includes a second rod 341 and a second elastic element 342. The second rod 341 is radially disposed on the outer wall of the third pipe 330 along the second pipe 120. The second elastic element 342 is sleeved on the second rod 341, with one end abutting against the outer wall of the third pipe 330 and the other end abutting against the inner wall of the second pipe 120. The second damping component 340 has a simple structure, enhances the radial buffering capacity of the cable tray support, and improves the seismic and impact resistance of the cable tray support. Furthermore, when subjected to external forces or thermal expansion and contraction during welding, the second elastic element 342 can provide flexible buffering in the radial direction, reducing stress concentration at the weld and preventing structural deformation or cracking due to welding stress.

[0065] Optionally, at least two sliders 311 are provided radially along the sliding plate 310, and the side wall of the second pipe 120 is provided with a slide rail 121 corresponding to the slider 311. The slider 311 and its corresponding slide rail 121 are slidably connected, which can provide guidance for the sliding plate 310 to move along the axial direction of the cable tray support, ensure the stability of the movement of the sliding plate 310, and thus improve the buffering effect in the axial direction.

[0066] Optionally, in this embodiment, the slide rail 121 is a sliding hole opened along the axial direction of the second pipe 120. In other embodiments, the slide rail 121 can be a sliding groove opened along the axial direction of the second pipe 120.

[0067] Specifically, the assembly process of the cable tray support provided in this embodiment is roughly as follows:

[0068] First, multiple second damping components 340 are uniformly fixed to the outer wall of the third pipe 330 through welding process, and the third pipe 330 is slidably welded to the sliding plate 310. Then, the first damping component 320 is welded to the upper surface of the sliding plate 310 to form a damping structure 300, which can effectively absorb and disperse the vibration energy from the transformer and cable tray.

[0069] Then, a connecting plate 210 is welded to the upper part of the first pipe fitting 220, and a positioning rod 230 is pre-welded to the center of the connecting plate 210 to form a visual positioning component 200. To ensure the integrity of the structure, the visual positioning component 200 is firmly welded to the second damping component 340, that is, the connecting plate 210 is welded to the lower end face of the third pipe fitting 330.

[0070] Finally, the second pipe 120 is fitted over the shock-absorbing structure 300, and the sliders 311 on both sides of the sliding plate 310 are slidably connected to their corresponding slide rails 121. The upper end of the second pipe 120 is inserted into the annular groove 112 of the support plate 110, and the second pipe 120 and the support plate 110 are welded to form a transformer bridge support with vibration reduction and visual positioning functions.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
