Description

Technical Field

[0001] The utility model generally relates to the technical field of container structures, and more particularly to a power distribution cabinet and a container. Background Art

[0002] Energy storage containers currently shipped to North America use AC480V / 60Hz power systems, which differ from those in China. The North American power grid operates at AC110V / AC220V, resulting in inconsistent voltage levels for lighting, fire protection systems, junction boxes, and liquid cooling units. These voltages range from AC110V to AC220V, requiring a step-down transformer to convert the local voltage to the required voltages for the equipment (AC110V or AC220V). In the market, each independent step-down transformer is typically placed separately in the electrical compartment, with one for each specification. This takes up space within the compartment and creates a complex layout. The power distribution cabinet integrates the entire energy storage container's power distribution system. During operation, the temperature inside the distribution cabinet and the energy storage container can rise, posing a fire hazard.

[0003] Therefore, it is necessary to provide a power distribution cabinet and a container to at least partially solve the above problems. Utility Model Content
