The invention relates to the technical field of power system operation and maintenance, and discloses a power distribution network load transfer method considering the oil temperature of a transformer, a power distribution network comprises a low-voltage-class transformer substation and a high-voltage-class transformer substation, and the load of the low-voltage-class transformer substation is powered by the high-voltage-class transformer substation; establishing a load transfer optimization model according to the topological structure of the power distribution network, wherein the load transfer optimization model comprises an objective function, a system operation constraint and a transformer oil temperature constraint; and according to the load transfer optimization model, transferring the load of the low-voltage-class transformer substation to another high-voltage-class transformer substation for power supply. The method solves the technical problem of how to ensure that the power grid bearing capacity and
