Abstract：Under the guidance of the“dual carbon” goal，the demand for fast reactive power regulation of the new power system is becoming increasingly prominent，and the condenser，as an important reactive power support equipment，is dificult to effectively improve its reactive power response speed and operation efficiency due to the limitation of the voltage resistance of the body in the past.The stator of an ultrahigh voltage direct-mounted condenser with a target capacity of 3O Mvar 35kV was taken as the design object，and the key designs such as cable winding and non-magnetic teeth were adopted to realize the direct connection between machine and network. Secondly，the stator cooling structure was designed，and the three-dimensional physical and mathematical models of fluid-heat transfer were established，the heat transfer law in the solution domain was revealed，and the related factors and changes affcting the thermal distribution were explored.The above research provides a research basis for the stator heat dissipation structure of ultra-high voltage direct-mounted condenser，and has certain universality in the research of cable-based winding motor system.

Keywords： ultra-high voltage condenser； cable winding； non-magnetic gear; cooling structure;thermal distribution
