Abstract
Description
Technical Field
[0001] This utility model relates to the field of busbar tap technology, and in particular to a busbar load tap that can replace a copper-aluminum plug box. Background Technology
[0002] In modern power transmission and distribution systems, busbars are widely used in switchgear and bus trunking systems due to their ability to carry large currents and their compact structure. As components for collecting and distributing electrical energy, load tapping devices are required to distribute current from the main busbar system to various power consumption units or secondary distribution lines. Currently, a common method is to use copper-aluminum plug-in boxes to achieve the connection from the main cable to the busbar and the extraction of current.
[0003] However, existing copper-aluminum junction boxes have revealed some shortcomings in practical applications. When multiple cables need to be tapped, these cables lack an effective organization and fixing structure after entering the junction box, resulting in the cables being randomly stacked or crisscrossed inside the box, causing the internal wiring to be very messy.
[0004] This chaotic cable layout not only makes the installation process time-consuming and laborious, but also seriously affects the later operation and maintenance. When it is necessary to inspect or replace a certain cable, maintenance personnel find it difficult to quickly and accurately identify and operate the target cable, which greatly increases the difficulty of maintenance and safety hazards. At the same time, it also makes the internal structure of the enclosure unclear and unsightly.
[0005] Therefore, this utility model proposes a busbar load tap to replace the copper-aluminum plug-in box, in order to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems existing in the technology of using copper-aluminum plug-in boxes as busbar load taps, such as messy internal cable routing, unclear structure, time-consuming and labor-intensive installation, and difficult subsequent inspection and maintenance, this utility model aims to provide a busbar load tap with an improved structure that can effectively solve the above problems and replace the copper-aluminum plug-in box.
[0007] This utility model provides a busbar load tap to replace the copper-aluminum plug box, including: a cable trough; a transfer box fixedly connected to the cable trough; and a cable fixing vertical beam fixed inside the transfer box.
[0008] The busbar load tap also includes a fixing plate, a busbar connector, a connecting plate, and a busbar plate.
[0009] The busbar connector is fixedly connected to the fixing plate, the connecting plate is fixedly connected to the busbar connector, and the busbar plate is fixedly connected to the connecting plate, forming a clear and complete current transfer path.
[0010] Furthermore, the connecting piece is connected to the cable trough by bolts and nuts. This combination method ensures that the entire current transfer assembly is firmly fixed to the foundation structure, thus ensuring the stability of the structure.
[0011] Preferably, the busbar load tap also includes a cable fixing crossbeam, which is fixed between the cable fixing vertical beams and is used to cooperate with the cable fixing vertical beams to separate the introduced cables.
[0012] Preferably, the cable fixing vertical beam and the cable fixing horizontal beam together form a grid structure for separating cables. The structure can effectively separate and organize multiple introduced cables, making the cable arrangement clear and avoiding cable tangling and mutual interference.
[0013] Preferably, the cross section of the cable fixing beam is a U-shaped groove structure. This structure facilitates the placement and positioning of the cable, allowing it to be stably fixed within the grid structure and preventing it from falling off.
[0014] Preferably, both the connecting piece and the busbar connector are sheet-shaped or block-shaped conductors, and they are stacked on top of each other. This stacking method makes the overall structure more compact and facilitates centralized connection and fixation.
[0015] Preferably, the connecting piece and the busbar connector are connected and fixed by bolts and nuts. Specifically, the bolts pass through the stacked connecting piece and the busbar connector and cooperate with the nuts to clamp and fix them. This connection method ensures the robustness of the mechanical connection and the reliability of the electrical connection.
[0016] Preferably, the fixing piece is a conductive metal piece, one end of which is used to fix the conductor part of the external cable, and the other end is overlapped and fixed to the busbar connector, serving as a transition component for the introduction of current from the cable to the adapter structure.
[0017] Preferably, the busbar load tap is provided with multiple fixing plates, multiple busbar connectors, multiple connecting plates, and multiple busbar plates, which are connected one-to-one according to the current path to meet the current transfer requirements of multi-phase cables or multi-circuit circuits and realize the synchronous distribution of multiple currents.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model, by setting up cable fixing vertical beams and cable fixing horizontal beams, together form a grid structure for separating cables, which solves the problem of messy cable routing and unclear structure inside the plug-in box in the prior art, and achieves the technical effect of making the cable arrangement neat, the overall structure clear and beautiful, and facilitating installation and subsequent maintenance.
[0020] 2. This utility model replaces the traditional copper-aluminum plug-in box with a complex structure by setting a clear current transfer path composed of a fixing plate, a busbar connector, a connecting plate, and a busbar plate. It solves the problems of complex structure and inconvenient maintenance of plug-in boxes in the prior art, and achieves the technical effects of simplifying the structure, making the current path clear, ensuring reliable connection, and facilitating maintenance.
[0021] 3. This utility model integrates the cable management structure and the current transfer structure into the transfer box, which solves the problems of chaotic cable management and current transfer functions and large space occupation in the prior art, and achieves the technical effects of compact structure, clear function, convenient installation, and improved safety and reliability of power distribution system.

[0031] Please refer to Figure 1 , Figure 3 and Figure 4 A fixing plate 7 is provided in conjunction with the busbar load tap. The fixing plate 7 is a conductive metal sheet. One end of the fixing plate 7 is used to fix the external cable, and the other end overlaps and is fixed to the busbar connector 6. The busbar connector 6 is fixedly connected to the connecting plate 3. Both the connecting plate 3 and the busbar connector 6 are sheet-shaped or block-shaped conductors and are stacked on top of each other. The connecting plate 3 is connected to the cable trough 1 by the cooperation of bolts 4 and nuts 5. The bolts 4 pass through the stacked connecting plates 3 and the busbar connector 6 and cooperate with the nuts 5 to clamp and fix them. The busbar plate 10 is fixedly connected to the connecting plate 3, thereby forming a complete current path from the external cable through the fixing plate 7, the busbar connector 6, the connecting plate 3 to the busbar plate 10.
[0032] like Figure 2 and Figure 4 As shown, cable fixing beams 9 are also fixed between the cable fixing vertical beams 8 inside the junction box 2. The cross section of the cable fixing beams 9 is a U-shaped groove structure. The cable fixing vertical beams 8 and the cable fixing beams 9 together form a grid structure for separating cables. The structure can separate and fix the introduced cables in an orderly manner, ensuring clear cable arrangement and avoiding mutual entanglement and interference.
[0033] As a preferred embodiment, in order to achieve orderly separation of the cables, such as Figure 2 and Figure 4 As shown, cable fixing beams 9 are fixed between the cable fixing vertical beams 8;
[0034] As a preferred embodiment, in order to facilitate the placement and positioning of the cable, the cross section of the cable fixing beam 9 is preferably a U-shaped groove structure, in which the cable can be accommodated.
[0035] In a preferred embodiment, the cable fixing vertical beam 8 and the cable fixing horizontal beam 9 cooperate with each other to form a grid structure for separating cables, so that multiple cables can be separated in different grid spaces, avoiding cable confusion and cross-interference.
[0036] As a preferred embodiment, in order to ensure good conductive contact and a compact structure, such as Figure 3As shown, both the connecting piece 3 and the busbar connector 6 are sheet-shaped or block-shaped conductors, and they are stacked on top of each other for centralized fastening and current transmission.
[0037] In a preferred embodiment, in order to achieve reliable mechanical fixation and electrical connection, the bolt 4 passes through the stacked connecting piece 3 and the busbar connector 6 and engages with the nut 5, thereby clamping and fixing the connecting piece 3 and the busbar connector 6 together, ensuring the tightness of the connection and the reliability of electrical conductivity.
[0038] In a preferred embodiment, the fixing piece 7 is specifically a conductive metal piece, one end of which overlaps and is fixed to the input end of the busbar connector 6.
[0039] As a preferred embodiment, in order to adapt to the switching requirements of multi-phase cables or multi-circuit circuits, this embodiment is provided with multiple fixing pieces 7, multiple busbar connectors 6, multiple connecting pieces 3 and multiple busbar pieces 10, which are connected one-to-one according to the current path, for example, corresponding to the current path of different phase lines, so as to realize the synchronous switching and distribution of multiple currents.
[0040] Working principle: During installation and use, the external cable is first introduced into the junction box 2. The cable is separated and arranged through a grid structure composed of cable fixing vertical beams 8 and cable fixing horizontal beams 9. The U-shaped groove structure of the cable fixing horizontal beams 9 facilitates cable placement. Then, the conductor end of the cable is fixedly connected to the fixing plate 7, and the current is transmitted from the cable to the fixing plate 7. Since the fixing plate 7 overlaps and is fixed to the busbar connector 6, the current is then transmitted to the busbar connector 6. The busbar connector 6 and the connecting plate 3 are stacked on top of each other.
[0041] The cable is clamped and fixed to the cable tray 1 by bolts 4 and nuts 5, and the current is then transmitted from the busbar connector 6 to the connecting piece 3. Finally, the connecting piece 3 is fixedly connected to the busbar piece 10, and the current is transmitted to the busbar piece 10 through the connecting piece 3, and then distributed to each power consumption point by the busbar piece 10. Through the neat arrangement provided by the above cable fixing components and the clear transfer path formed by the fixing piece 7, busbar connector 6, connecting piece 3 and busbar piece 10, the problems of messy cable routing and unclear structure inside the copper-aluminum plug box in the prior art, which lead to difficulties in installation and maintenance, are effectively solved.
