The invention relates to an oil changing device for a hydraulic station and belongs to the technical field of hydraulic pressure. The oil changing device for the hydraulic station comprises an oil outlet pipeline communicating with an oil outlet of a hydraulic station oil tank as well as a clean oil changing loop and an execution loop which are branched at the tail end of the oil outlet pipeline; an oil return pipeline is arranged at an oil return port of the oil tank; the oil outlet pipeline, the clean oil changing loop and the execution loop are connected and controlled to be opened and closed through a rotating reversing valve; and the oil return pipeline communicates with the oil return end of the clean oil changing loop and the oil return end of the execution loop respectively. The oil changing device is added on the basis of an existing hydraulic station hydraulic loop, self-circulation cleaning can be performed on original hydraulic oil, old oil pumping and new oil changing can also be conducted, the o
