Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of the Chinese Patent Application No. 202323213443.2 filed on Nov. 24, 2023, which is hereby incorporated by reference as if fully set forth herein.

FIELD

The present disclosure relates to the technical field of power supply, and in particular to a prefabricated alternating-current integrated power module.

BACKGROUND

According to conventional power distribution solutions, a medium-voltage power distribution device, a transformer device, a low-voltage power distribution device and an uninterruptible power supply are independent components that are not interconnected with each other and are only physically placed together. These devices have different appearances, and cabinets cannot be connected with each other based on the frameworks of the devices. Electrical energy transmission can only be performed between devices via cables, resulting in a large footprint, a long on-site delivery time period, and difficult maintenance and repair. In addition, according to the conventional solutions, uninterrupted maintenance and repair on the uninterruptible power supply are usually not supported. For specific scenarios, such as a power distribution system of a bank and a power distribution system of an important data center, a power outage may cause a catastrophic consequence, resulting in financial losses and a significant impact on customer service and operations. Therefore, the limitations of the conventional power distribution solutions are particularly apparent in these scenarios.
