The invention relates to a self-healing method for a transformer respirator moisture absorption device and belongs to the accessory field of transformers. The method is characterized in that a two-wayswitchable respirator composed of first and second silica gel tanks, an electric switching valve and a two-way breathing valve is arranged on a gas path connecting a transformer oil pillow with the outside; firstly, a gas path of the first silica gel tank is turned on; when the moisture in the first silica gel tank exceeds the threshold, switching to a gas path of the second silica gel tank is performed; the silica gel in the first silica gel tank is heated and regenerated; when the moisture in the first silica gel tank returns to a predetermined value, heating of the first silica gel tank isstopped, and the first silica gel tank enters a standby state; when the moisture in the second silica gel tank exceeds the threshold, switching to the gas path of the first silica gel tank is performed; and the silica gel in
