The utility model belongs to the field of power transformers, especially relates to an intelligent assembly of an integrative power transformer. A main LED, a state monitoring LED, a neutral point current transformer merging unit, a process level network switch and a hard pressure plate in non-power protection are mounted in a frame of a cabinet of the intelligent assembly, and measurement, monitoring, controlling and protection on the transformer are realized. An installing plate is arranged on the other side of the cabinet. A transformer cooling control system is arranged on the installing plate. The transformer cooling control system comprises a current transformer, a voltage supervision relay, a breaker, a contactor and a motor starter arranged on the installing plate. A swing door is arranged on the cabinet of the intelligent assembly. A LED lamp, a button, a change-over switch and an ammeter are arranged on the swing door, used for monitoring and controlling on the transformer cooling control system. The external information of the intelligent assembly provided by the utility model follows the IEC61850 protocol, standardization modeling is performed on the information, hence connecting with a secondary apparatus in a transformer station and various body state monitoring apparatuses is convenient.
