The invention discloses a transformer heavy gas action setting method based on surging oil flow acceleration, which comprises the following steps: applying external excitation sources with different degrees to an oil way pipeline to generate different surging oil flows; flow velocity signals of transient oil flow are collected based on a flow velocity sensor, and flow velocity curve graphs of different surging oil flows are generated; collecting a gas relay baffle corner signal based on the gas relay, and generating a baffle corner curve graph under different surging oil flows; based on the flow velocity curve graph and the baffle rotation angle curve graph, the acceleration values and the change trends of the corresponding surging oil flow when the heavy gas action just occurs under different surging oil flows are analyzed and compared, and the acceleration setting value of the surging oil flow when the heavy gas action occurs is determined; and judging whether a heavy gas action occurs or not based on the a
