Abstract： Highaltitude power transformer isan important partofpower transmission.This paperanalyzes its structure andtest differences，which is of great significance for energy development and construction.Through analyzing the characteristics of high-altitude environment， this paper introduces the infuence on the internal structure and shapeof power transformer intheaspects of the air gapand insulator ininsulation factors，andfuel tank size，cooling method and cooling method of heat disspation factors.It analyzes the differences between high altitude power transformers used in national standards such as GB/T1094.2-2013，GB/T1094.3-2017and GB/T1094.1-2022 and those used under normal conditions in temperature rise test，outer insulation air gap and outer application withstand voltage.
