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.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a centralized charging cabinet. Background technique [0002] As environmental problems become prominent, many countries around the world have formulated policies to support the development of electric vehicles, and the supporting electric vehicle charging systems have also been continuously improved. [0003] figure 1 It is a schematic structural diagram of a charging system in the prior art. Such as figure 1 As shown, the charging system includes a distribution station, a switch box, and charging equipment. Among them, the 10kV high-voltage power is connected to the 10kV switch box, and the 10kV switch box is connected to the 10kV / 0.4kV distribution station through a connecting line. The station includes multiple transformers, and the charging equipment includes multiple rectification units. The transformers are connected to the rectification units one by one. The ...
