The utility model relates to the technical field of transformer oil recharging, in particular to an automatic oil recharging device for a transformer, which comprises an oil conservator, an oil level gauge, an oil tank, a control unit, a motor, an oil pump, an oil inlet pipeline, an oil outlet pipeline, an electromagnetic valve, a heating device and a temperature detection device. The device is reasonable and compact in structure and convenient to use, and when the control unit receives an over-low oil level signal sent by the oil level indicator, the control unit automatically controls the motor to drive the oil pump to extract transformer oil from the oil tank and supplement the transformer oil to the oil conservator until the over-low oil level signal is relieved; when the control unit receives an over-high oil level signal sent by the oil level indicator, the control unit automatically controls the electromagnetic valve to be opened to discharge redundant transformer oil in the oil conservator into the oi
