Description

Technical Field

[0001] The utility model relates to the technical field of laminated busbars, in particular to a laminated busbar used for an energy storage distribution cabinet. Background Art

[0002] Laminated busbar, also known as laminated busbar or composite copper busbar, is a multi-layer composite structure connection bar, which can be regarded as the highway of the power distribution system. Compared with the traditional, bulky, time-consuming and troublesome wiring method, the use of composite busbar can provide a modern, easy-to-design, fast-to-install and clearly structured distribution system. It is a high-power modular connection structure component with repeatable electrical performance, low impedance, anti-interference, good reliability, space saving, simple and quick assembly. Composite busbars are widely used in power equipment such as energy storage distribution cabinets.

[0003] However, the stacked busbars in existing energy storage distribution cabinets are usually a whole plate structure. When connecting more cables, multiple stacked busbars need to be installed, which takes up more space in the energy storage distribution cabinet. If more connection end holes are opened on a single stacked busbar, the heat dissipation efficiency of the stacked busbar will be affected. Therefore, it does not meet the existing needs. In this regard, we propose a stacked busbar for an energy storage distribution cabinet. Utility Model Content

[0026] The connecting conductive shaft 2 is fixedly mounted on the upper end of the insulating mounting plate 1. Six laminated busbars 5 of different specifications are installed on the outside of the connecting conductive shaft 2 through a card slot. The laminated busbars 5 are installed so that they are connected to the connecting conductive shaft 2 through the card slot. The staff can rotate the laminated busbars 5 according to the use requirements to expand the laminated busbars 5. The six staggered laminated busbars 5 can be used to connect more cables in a limited space and facilitate the heat dissipation of the device. When connecting multiple cables, only one needs to be installed, so that the device only needs to be installed on one side, which greatly reduces the installation strength of the staff and makes the device more practical. The upper ends of the six laminated busbars 5 are all provided with matching bosses 6. The upper end of the connecting conductive shaft 2 is provided with a fastening insulating end cover 7. The fastening insulating end cover 7 is connected to the matching boss 6 through a card slot. The outer side of the laminated busbar 5 is provided with an arc-shaped connecting portion 16. The installation of the arc-shaped connecting portion 16 can increase the contact area between the device and the air, which is beneficial to the heat dissipation of the device. At the same time, the device can be installed with more cables, enhancing the practicality of the device.

[0027] An insulating ceramic plate 9 is arranged on one side of the outside of the fastening insulating end cover 7. A mounting groove 10 is arranged on the upper end of the insulating ceramic plate 9. A thermometer 11 is fixedly installed inside the mounting groove 10. The thermometer 11 can detect the temperature of the device when it is working, which is convenient for the staff to know the use of the device and make the device more humane. Dust scraping triangle strips 15 are fixedly installed on the front and rear ends of the laminated busbar plate 5. The installation of the dust scraping triangle strips 15 allows the staff to rotate the laminated busbar plate 5 when installing the device, so that the dust scraping triangle strips 15 can scrape off the dust on the upper end of the laminated busbar plate 5 to prevent the dust from affecting the connection between the cable and the device.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An insulating ceramic support foot 13 is installed on one side of the lower end of the laminated busbar plate 5. Installing the insulating ceramic support foot 13 can support heat conduction, prevent the laminated busbar plate 5 from tilting, and effectively extend the service life of the device. The insulating ceramic support foot 13 is fixedly connected to the laminated busbar plate 5, and an anti-sway top screw 14 is installed inside the insulating ceramic support foot 13. The anti-sway top screw 14 is connected to the insulating ceramic support foot 13 by threads. Six mounting holes 3 are arranged inside the insulating mounting plate 1, and bottom fixing screws 4 are installed inside the six mounting holes 3. The upper ends of the laminated busbar plate 5 and the arc-shaped connecting part 16 are provided with connecting end holes 12, and several connecting end holes 12 are arranged. The arc-shaped connecting part 16 and the laminated busbar plate 5 are arranged as an integrally formed structure. Ten dust scraping triangle bars 15 are arranged, and the fastening insulating end cover 7 is fixedly connected to the insulating ceramic plate 9. The upper end of the fastening insulating end cover 7 is installed with a top fixing screw 8, and the top fixing screw 8 is connected to the connecting conductive shaft 2 by threads.

[0029] Working principle: When in use, the staff installs the device inside the energy storage distribution cabinet, and then uses the bottom fixing screws 4 to fix the insulating mounting plate 1 to the energy storage distribution cabinet. The staff then rotates the laminated busbar plate 5 to scrape off the dust with the dust scraping triangle strip 15 on the outside of the laminated busbar plate 5. The staff then connects the cables to the connection end holes 12 through terminals and screws according to usage requirements. Finally, the staff adjusts the angle of the laminated busbar plate 5 so that the cables are offset from each other and evenly distributed outside the device. The staff then uses an inner hexagonal wrench to tighten the anti-sway screw 14 and uses an outer hexagonal wrench to tighten the top fixing screw 8 to fix the position of the laminated busbar plate 5. The device installs the laminated busbar plate 5 so that it is connected to the connecting conductive shaft 2 through a slot, so that the staff can rotate the laminated busbar plate 5 according to usage requirements to expand the laminated busbar plate 5. The six offset installed laminated busbar plates 5 can be used in a limited space. More cables can be connected and the heat dissipation of the device is convenient. When connecting multiple cables, the device only needs to install one, so that the device only needs to be installed on one side, which greatly reduces the installation strength of the staff and makes the device more practical. Installing the arc-shaped connecting part 16 can increase the contact area between the device and the air, which is beneficial to the heat dissipation of the device. At the same time, the device can be installed with more cables, enhancing the practicality of the device. Installing the thermometer 11 can detect the temperature of the device when it is working, which is convenient for the staff to know the usage of the device and make the device more humane. Installing the dust scraping triangle bar 15 can enable the staff to rotate the laminated busbar plate 5 when installing the device, so that the dust scraping triangle bar 15 can scrape the dust on the upper end of the laminated busbar plate 5 to avoid the dust from affecting the connection between the cable and the device. Installing the insulating ceramic support foot 13 can play a role in supporting heat conduction, prevent the laminated busbar plate 5 from tilting, and effectively extend the service life of the device.
