Abstract In view of the characteristics of high speed electric railway with heavy load and strong volatility, this paper establishes a mathematical model for the dynamic over-load protection, based on the heat balance different equation, to determine how temperature increases with the change of the protection traction transformer’s current, and the intelligent traction transformer over-load protector are designed with the setting method based on typical load curve. Through the analysis of actual load of traction transformer, the results show that the method can make full use of the transformer overload capacity and reliably protect the transformer from insulation aging caused by overheating.
