The invention discloses an oil-immersed transformer based on a cooling protection device in the technical field of oil-immersed transformer equipment. The oil-immersed transformer comprises a shell. Arecycling water tank is arranged at the bottom end of the shell. Supporting legs are symmetrically arranged at the left and right of the bottom end of the recycling water tank. Two movable plates arearranged in the inner cavity of the shell in a sliding mode, and the two movable plates are respectively located on the upper and lower sides of the inner cavity of the shell. When the transformer isin use, a water curtain is formed on a cooling water curtain, the internal temperature of the shell is rapidly decreased through the water curtain and a negative pressure fan based on the principle of heat absorption during water evaporation, and thus, the transformer body is cooled. The cooling environment protection effect and the electricity saving effect cannot be achieved by other cooling equipment. Water loss can be
