[0002] When arranging the wiring layout of the energy storage system busbar cabinet, the power distribution part often faces the need to arrange dozens or even hundreds of terminal blocks. Taking the most commonly used model ZDU-2.5 as an example, arranging all the terminal blocks on the panel requires arranging them in at least two or three rows or even more, which makes it difficult to install the terminal blocks at the back. Workers cannot directly visually observe the status of the terminal blocks at the back, affecting the installation efficiency. In addition to the problems brought by the large number of terminal blocks, the existing busbar cabinets are also accompanied by a large number of miniature circuit breakers, which are larger in size and need to be manually opened and closed. Therefore, when arranging the layout, not only the rationality of the wiring needs to be considered, but also the operation and maintenance of on-site operators need to be facilitated. For the busbar part, 24 clusters or more clusters of cables need to be connected. Each cluster needs to be equipped with a fuse, and enough operable space needs to be left between the fuses. The numerous components and cables make the limited space inside the cabinet more compact. Therefore, a reasonable and efficient wiring layout design is crucial. Therefore, it is crucial to invent a busbar cabinet that can improve the production and installation efficiency, be compatible with the needs of different clusters, and is conducive to the standardized design of the cabinet body.
