The invention provides an underground pulse transformer structure based on high-temperature superconducting magnetic energy storage and a principle design method, and belongs to the technical field of pulse power. The pulse transformer is characterized in that the pulse transformer structurally comprises a refrigerating machine, a transition connecting rod, a fixed insulating sleeve, a sealing ring, a control module, an external drill rod, an elastic insulating layer, a Dewar layer, an insulating fixed clamping sleeve, a transformation module, a fixed chuck, a high-voltage cable and the like. According to the underground pulse transformer structure and principle design scheme based on high-temperature superconducting magnetic energy storage, a traditional transformer wound by an iron core is replaced by a high-temperature superconducting air-core pulse transformer, and a superconducting inductor is used for replacing a capacitor for energy storage in the aspects of energy storage and output; the transformer i
