Fault diagnosis processing system of distribution transform monitoring terminal and diagnosis method of system

The invention relates to a fault diagnosis processing system of a distribution transform monitoring terminal and a diagnosis method of the system, and belongs to the technical field of operation safety of the power distribution network. The system comprises the distribution transform monitoring terminal, a prepositioned collector, a processor, a memory, a diagnosis machine, an instruction generator and a man-machine interaction interface. The fault attribute of a device is found according to the type of the collector, the attribute of the distribution transform monitoring terminal and the data attribute of the device of the distribution transform terminal, a hypothesis scheme is selected according to the fault attribute to solve concrete problems in fault identification, and a clustering algorithm is used to carry out cluster analysis and fault determination on data of an electric energy terminal. The system and method are applied to onsite fault elimination of the distribution transform monitoring terminal,
