摘要： The present disclosure provides a centralized charging cabinet, including: a charging cabinet, provided with an isolation area and a charging area therein; an isolation transformer, provided in the isolation area; and at least one charging unit, provided in the charging area, where each of the charging unit is electrically connected to a secondary winding of the isolation transformer through a plurality of first connection structures, and the plurality of first connection structures are located at a back region of the charging area. In the centralized charging cabinet, the isolation transformer is provided in the isolation area inside the charging cabinet, the charging unit is provided in the charging area inside the charging cabinet, which realizes a centralized layout of the isolation transformer and the charging unit and improves the space utilization. Disposing the charging unit in the charging cabinet can reduce a design requirement of a casing of the charging unit. In addition, dividing the charging area into the back region and the front region and disposing a power line connecting the isolation transformer and the charging unit at the back region that is not easily accessible, thereby achieving high-voltage area isolation and improving safety of the centralized charging cabinet.
