The invention provides a centralized charging cabinet, which comprises a charging cabinet body, an isolation transformer and at least one charging unit, wherein the cabinet body is internally providedwith an isolation area and a charging area; the isolation transformer is arranged in the isolation area; the at least one charging unit is arranged in the charging area; each charging unit is electrically connected with a secondary winding of the isolation transformer through a plurality of first connecting structures; and the plurality of first connecting structures are located in a back area ofthe charging area. According to the centralized charging cabinet, the isolation transformer is arranged in the isolation area in the charging cabinet body, the charging unit is arranged in the charging area in the charging cabinet body, centralized layout of the isolation transformer and the charging unit is achieved, and the space utilization rate is increased. The charging unit is arranged in the charging cabinet body, and the design requirement of a charging unit shell can be reduced. In addition, the charging area is divided into the back area and the front area, a power line, which connects the isolation transformer and the charging unit, is arranged in the back area which is not likely to be touched, high-voltage area isolation is achieved, and the safety of the centralized chargingcabinet is improved.

    本发明提供一种集中式充电柜,包括:充电柜体,其柜体内部设置有隔离区和充电区;隔离变压器,设置在隔离区内;至少一个充电单元,设置在充电区内;其中,每个充电单元通过多个第一连接结构与隔离变压器的副边绕组电连接;且多个第一连接结构位于充电区的背面区域。在该集中式充电柜中,将隔离变压器设置在充电柜体内部的隔离区,将充电单元设置在充电柜体内部的充电区,实现隔变压器和充电单元的集中式布局,提高空间利用率。将充电单元设置在充电柜体内,能降低充电单元外壳设计要求,另外,将充电区分为背面区域和正面区域,并将隔离变压器与充电单元连接的功率线置于不易接触到的背面区域,实现高压区隔离,提高集中式充电柜的安全性。
