The invention relates to the technical field of substations, and particularly relates to a compact American-type substation, which comprises a high voltage chamber, a low voltage chamber and a transformer chamber, and is characterized by further comprising a terminal control chamber, wherein the high voltage chamber is divided into a high voltage switch cabinet and a high voltage wire incoming cabinet; the low voltage chamber is divided into a low voltage general switch cabinet, a low voltage feeder line cabinet and a compensation cabinet; the compensation cabinet is internally provided with a compensator; the terminal control chamber is internally provided with a microcomputer comprehensive protection device, a meter, a high voltage on-load voltage regulation device and a data transmission unit; the high voltage chamber, the low voltage chamber and the terminal control chamber are arranged inside the box body; and the transformer chamber is located outside the box body. According to the compact American-type substation, the structure is simple, maintenance and feeder line increasing are convenient, intelligent management is realized conveniently, the working process is reduced due to phase sequence adjustment, reserved space is reduced, the covered area is reduced, remote control, remote communication and remote measurement on electrical equipment can be realized, and remote power grid data acquisition, detection, control and other performance requirements by the user can be met.
