The application discloses an overload automatic switch strategy making method for a dedicated transformer terminal and relates to the technical field of automatic control of dedicated transformers. The overload automatic switch strategy making method adopts an overload judgment rule containing a judgment branch one and a judgment branch two. The judgment branch one identifies a conventional electrical overload based on an overload current multiple and an equivalent thermal current. The judgment branch two identifies an implicit temperature overload based on real-time temperature. The overload grade from a pre-warning grade to a short-circuit grade is determined in combination with a reverse time limit time, and a corresponding switch control strategy is matched. The method effectively avoids the defects that a single current judgment cannot reflect thermal inertia, distinguish false disturbances and cover implicit overloads. Through multi-dimensional coupling verification and hierarchical disposal, the method not only filters false actions caused by short-time impacts, but also accurately captures thermal accumulation overloads and temperature overloads, thereby guaranteeing power supply continuity while avoiding damage to equipment caused by overloads.
