The invention belongs to the field of power equipment control, relates to a transformer management technology, is used for solving the problem that potential safety hazards exist in the mode that an existing transformer monitoring and management system adopts a unified and fixed threshold value to judge the operation state of a transformer, and particularly relates to a transformer monitoring and management system based on big data analysis. Comprising a monitoring management platform, and the monitoring management platform is in communication connection with an operation analysis module, an early warning module, a service life analysis module, a storage module and a controller. The early warning module comprises a red signal lamp for indicating emergency power failure, a yellow signal lamp for indicating abnormal operation and a green signal lamp for indicating normal operation; the operation state of the transformer is detected and analyzed in real time through the operation analysis module, and the operation coefficient is calculated through the operation parameters of the transformer, so that the transformer is protected, aging acceleration caused by excessive use of the transformer is prevented, and the service life of the transformer is prolonged.
