Oil-immersed transformer overload monitoring method and related equipment

The invention discloses an oil-immersed transformer overload monitoring method and related equipment. The method comprises the following steps: acquiring load current data of a transformer; judging whether the transformer is in an overload state or not based on the load current data; when the transformer is in the overload operation state, basic data of the transformer are monitored, and whether the transformer meets an overload preset operation condition or not is judged based on the operation data; if the transformer meets the preset operation condition, operation data after preset time is predicted based on the operation data, and monitoring and prediction of the overload capacity of the oil-immersed transformer are completed; and when the operation data after the preset time exceeds the overload preset operation condition, outputting alarm information. According to the invention, accurate monitoring and prediction in overload operation of the oil-immersed transformer are realized, and the defects of exten
