Description

Technical Field

[0001] This article belongs to the technical field of bus ducts, and specifically relates to a parallel distributed large-capacity sliding rail bus system. Background Art

[0002] With the rapid popularization and iterative updates of AI technology, the global AI wave has begun to surge, and more and more data centers have begun to transform into AI intelligent computing centers. The demand for electricity in AI intelligent computing centers far exceeds that of general data centers. The original large number of small and medium current data center bus ducts on the market cannot carry the high current demand of 800-1250A. In the face of future market demand, it is necessary to upgrade and develop a data center bus duct with higher current carrying capacity.

[0003] In order to facilitate connections, most of the existing data centers use center-split rail bus ducts to facilitate the expansion of plug-in boxes and quick adaptation and connection. However, the PE grounding bars in the existing center-split bus ducts are usually set inside the bus duct, which will greatly compress the internal space of the bus duct, resulting in the bus duct being able to withstand currents that are not particularly high, and therefore cannot carry high-load currents. Summary of the invention

Two parallel-arranged single-channel busbars are connected through an intermediate connection component, and a jumper design is set at the end and each connector to maintain current balance, ensuring balanced current distribution in the system and preventing single-phase overload. The parallel distribution design can also support a double-row plug-in box design, effectively meeting the needs of ultra-large data center loads of more than 80kW per cabinet.
