| Zusammenfassung: | The utility model discloses a traction transformer based on natural ester insulating oil, which comprises a shell and a voltage regulating winding arranged in the shell, and the shell is also filled with the natural ester insulating oil. The voltage regulating winding is wound on the single-phase double-column transformer body structure iron core and is arranged in pair with the main winding of the single-phase double-column transformer body structure iron core; oil ducts are arranged on the inner side and the outer side of the voltage regulating winding, and natural ester insulating oil passes through the oil ducts. The traction transformer adopts the natural ester insulating oil, and the voltage regulating winding is redesigned for the natural ester insulating oil, so that the traction transformer adapts to the characteristic of high viscosity of the natural ester insulating oil, and the problem of environmental pollution caused by mineral oil can be avoided.
